I've got too many ideas and too little time. I suspect others may feel the same about themselves. However, there may be some of you who have more time than ideas, and you folks can probably make people happy by bringing to life some extra otherwised unused ideas. So, let's dump some ideas here, whether complete or half-baked, and let others run with them. Sound good?
I'll start with these:
Idea: I'd like to see someone build a pedal using macaroni art for graphics (with alphabet pasta labels).
Idea: I'd like to see someone build a pedal named Resting Bitch Face (my wife used the phrase recently, and it struck me as awesome :icon_razz:).
QuoteI'd like to see someone build a pedal named Resting Bitch Face (my wife used the phrase recently, and it struck me as awesome :icon_razz:).
I'd like to see a pedal named "Muff Squeezer" in honor of Donald Trump.
Idea: I'd like to see someone build "The Cagey Bee's Pi":
https://www.diystompboxes.com/smfforum/index.php?topic=120975.msg1134727#msg1134727
low pass filter around 220hz -> sub octave generator
high pass filter around 165hz -> big muff clipping circuit
blend (bypassed by switching octave-out jack)
some sort of tone stack
inspired by a two-piece metal band I saw
breadboarded but I quickly gave up trying to troubleshoot. Will give another stab at it
Idea: How about a pedal with aesthetics and construction inspired by one of these?

These fuzz names are just terrible :icon_lol:
I had an idea for a pedal to be called Log Arrhythmia which would use log - antilog generation but it would be terrible for anything with more than one note at a time because of intermodulation. It still might work on a theremin.

Yeah, once fuzz became muff in the 70s it has been downhill.
Any pranksters out there? There might be enough time for you to design and build one of these musically unuseful ideas before April 1st (and, yes, I did at one time fully intend to unleash both of these upon the unsuspecting world :icon_twisted:):
1. The Swear Jar: an envelope detector triggers the replacement of the normal audio with a 1kHz "bleep" (optionally a different, more musical frequency). Bonus points for a remotely-activated design, especially one that could work with a microphone.
2. The B♭us (B flatus), or more discretely named, Beef Lattice: Notch filters remove B♭ frequencies and a farty sound of corresponding magnitude is inserted.

A Burst Box clone!

my version of an enveloped tremolo. Speed up or speed down.

Could be fun to implement one of those record/playback modules and have pre-recorded swear words inserted into the signal path at sporadic intervals.
Build an overdrive using instrumentation opamps.

Idea: An op amp circuit that saturates with modulated power rail voltages. (I suppose it doesn't have to be an op amp, but it was an op amp datasheet that sparked the idea.)

Maybe. Depends on the shape and frequency of your modulating signal, I suppose.

I did something like this, only the opamp acts as the power rail:

I did exactly this with a slightly warped definition of modulation...
Basically connected a resistor to the power supply of an MXR micro amp (modded for extra gain). Classic "dead battery" circuit.
As the output changes, the circuit uses more power and therefore the opamp's supply changes with respect to the output signal. Just on the verge of oscillation you can get an octave down effect!
I could make a demo...
do it up, caveman!

Threw one of these together to replicate the intro to One of These Days on the strat while using the tremolo arm.
3rd Floyd reference of the day here for me.
the intro is two basses, gilmour on one side, waters on the other. beaucoup binson echorec applied!!
the tremolo part i bet it would work tho ;)

Woah interesting! I've tried recreating many of their effects - even a backwards wired wah for the end of Echoes. I've gotta look into that a bit more.
It was when I was first messing with LDRs. I had a friend frantically switch the lights on and off with the fuzzed up signal going through only an LDR on breadboard. Must have looked like a poltergeist from the outside. Eventually I threw one together with a tremolo circuit but parted with it.

Sounds like you more or less manually did what my Creaky Floor circuit does (see the second demo video in particular):

It isn't a pedal so there :P
Ah call it HUGE KNOB and literally have a really giant knob...
I'm now thinking if I should use a 1590A and put a giant knob on it. Boost pedal or something.
The largest knob I can get is about 50mm... big enough? (Ordered a 45mm knob together with pedal parts stuff, i realized a 1590A is only 36mm and this is going to be so comically oversized)

My DIY guitar stuff didn't happen until 2001, when I wanted to build a Freddie Fuzz clone because Scott Henderson used one and I liked his sound. I got it working the day my daughter was born, Oct. 20. Ever since then I've been messing with one thing or another except for a couple of years when I was going thru death of my parents, etc.
I didn't start playing guitar until I was 20 years old, taught myself that as well as this electronics stuff. I learned enough to be dangerous, I'm certainly not any kind of guru.
Idea (a very rough beginning of an idea, anyway):
If I remember correctly, this water cup effect in Jurassic Park was made using a guitar string attached to the underside of the car dashboard.
Could such a water ripple be used to control some sort of guitar effect, thus bringing the movie effect full circle?

Thinking more of a reverb tank only its using water ripple with some kind of vibration transducer attached to the bottom of the tank and a vibration sensor in the half full water tank yada yada use it as a reverb tank :icon_mrgreen:
I've been meaning to tweak this in spice, build, and tweak further for several months now. Maybe someone can beat me to the punch and see how it turns out:

I am tired of all the hum / buzz / power line noise issues. Someone build a complete pedalboard set that uses fibre optics to connect one pedal to another and the guitar and amp too. Positive supply Fuzz Face versus negative? Nobody will care anymore and there will be no need for polarity inverters for the power supply. The charge pump market may tank but the sound will be better. In fact, I bet you could do an awesome fuzz with phototransistors if you used both bias and light control. Hey, steal that one!

How would you go about that in practice? S/PDIF? That can do two channels of PCM data. Somewhat short-haul; limited to 10 meters/~30 feet. Then, would you do the effects in digital form? Or convert back to analog and use good, ol' fashioned circuits to perform the heavy lifting? This could mostly be done right now with off-the-shelf components, so it's not a far-fetched idea.

I may be wrong, but I think amptramp meant analog light modulation, without ADC-DAC.
That's going to be a lot harder.
Has anyone ever built a pedal inside a hollowed-out book?
I have an old biscuit tin in the shape of a book. Too big for a pedal and too thin for standing on. I was going to turn it into an amp or a cigar-box guitar. Right now it's languishing on a shelf looking like, well, a book.

The charge pump market may tank but the sound will be better. In fact, I bet you could do an awesome fuzz with phototransistors if you used both bias and light control. Hey, steal that one!
How would you go about that in practice?
</snip>
The MIDI interface did exactly that about 35 years ago. Everything is coupled via opto-isolators to avoid ground-loops and hum problems. And for exactly these reasons - it would have been nightmare otherwise. Admittedly it doesn't run at audio rates, but the principle is good at least. I guess the bandwidth of fibre optics is where it wins over simple opto-isolators, but I wouldn't be sure sure it couldn't be done with simple photo-transistors until I'd proved otherwise.

Has anyone ever built a pedal inside a hollowed-out book?
Yes, i did!
Was a very basic fuzz, using a sziklai pair consisting of a Si and a Ge transistor.
I later rehoused it because of noise issues

How would you go about that in practice? S/PDIF? That can do two channels of PCM data. Somewhat short-haul; limited to 10 meters/~30 feet. Then, would you do the effects in digital form? Or convert back to analog and use good, ol' fashioned circuits to perform the heavy lifting? This could mostly be done right now with off-the-shelf components, so it's not a far-fetched idea.
I may be wrong, but I think amptramp meant analog light modulation, without ADC-DAC.
Correct, I did mean a fibre optic analog interface. There are circuit designs that use an optoisolator for the output and an optoisolator for the feedback in an op amp circuit with the LED's in series so the signal fed back is similar to the signal fed to the next pedal in the chain.
(https://www.electroschematics.com/wp-content/uploads/2015/03/Linear-DC-Signal-Opto-Isolator-Schematic-550x351.jpg)
The difference I would like to see is the LED in the transmit side and the receiving optotransistor in the other with a fibre optic connection between them.
I had an idea that popped into my head about a month ago. It's hard to believe that serious drugs were not responsible for this. What about air stomp boxes for use when playing air guitar? You could have a whole range of pedals; fuzz, distortion, overdrive, reverb, chorus, flanger, wah, etc., etc. This could be expanded to a whole range of accessories; air picks, air straps, etc. And you heard it here first!

I could make tons of these! :icon_razz: I would worry that I would eventually get very lazy doing so, however, because no one could see where I cut corners in construction. That lack of accountability would be my downfall. :icon_frown:
IL300 was the usual choice for output+feedback optocouplers if you want to go further. Could be nice for a compressor or something.
I fear the analog optical transceivers are not linear enough (may be a feature, not a bug!) for general use. Also, fiber is kinda fragile for road use.

I want to do a Big Muff in dead bug style and call it Bug Muff.
I would like to see a cavity resonator drum.
Using the usual dimensions of a drum, this would be an oscillator in the VHF or UHF frequency band. You would have an envelope detector for each resonant frequency (a drum has resonances that are Bessel functions of the zeroth order) and a divider that would bring the frequencies down from the order of a hundred MHz to the audio band. The resultant frequencies would be multiplied by the envelope and you would recover a drum sound, all without the need for a microphone, avoiding the direct feed of ambient sound (except as it affects the drum skin). The drum would have a conductive layer on the sides and conductive film on the skin.
To get a snare drum, the snare could be laid beside a rigid conductor and charged to a high voltage. The movement of the snare would induce a voltage based on V dC/dt. In this case, the varying capacitance is what induces the voltage.

You can get photosensitized circuit boards that you expose with the pattern you want. Why not enclosures? You take it to your dark room, set up the etch pattern you want on a projector, expose the box and drop it in the etch chemicals. No toner, no transfer, no repurposed steam iron, just an enclosure that you drop in acid when you are satisfied with the image. Someone on this site with photography equipment should try this.

Photography equipment is a flea market / antique store / estate sale item now. Or you could use a projection display showing a jpeg of the image you want to see on the enclosure.
You could perhaps print an image onto clear film and use that as a photomask as well. I think I've seen silk screening setups created like this (but it was many years ago, so the details are hazy).
Instead of using etching to decorate enclosures, there are miniature sandblasting guns used to etch glass. Some enterprising individual will start using this to manufacture enclosures using rubber or vinyl templates. Need more etch depth? Just press the trigger a little longer. Need bas relief? These things do that.

It's x5 PT2399's arranged at the 5 points of a pentagon star. Reading clockwise, each delay inputs the angle from the left and outputs to the right. One delay is chosen for signal input mix, and another (could be the same one) for output mix. The audio will travel through all 5 in turn and back again endlessly. Arrange path in anticlockwise direction for Death Metal.

I shoved most of a pro darkroom into my attic 20 years ago. It's still there and, the older I get, the heavier it seems to be so it'll stay there. My wife says that if I put anything else up there, the house will be so top heavy it'll turn over in a light wind.
There is electric up there and it's pretty dark.. Might be worth a play

You'd probably *have* to do it that way... photoresist (like this (https://www.aliexpress.com/item/100g-Photoresist-Anti-etching-Blue-Ink-Paint-for-DIY-PCB-Dry-Film-Replacement/32598402032.html?spm=a2g0w.10010108.1000001.12.83597b47UoqO7S)) requires UV light, which would require an enlarger lens FAR more expensive than, say, a laser-etching setup.
(edit) It's probably also easier that way... enclosures are neither big-enough nor small-enough to be worth mucking-around with an enlarger, even if any old lens would do.
I'm not sure if that photoresist is burly enough for enclosures, but it's certainly worth a try.
Hmm. This one has piqued my interest. I can convert an enlarger head to UV if necessary and my optics were top of the range back in the day.
Before going down that route however, I'm going to run a series of tests on the effective resilience to etch chemistry to various, easily created photo chemical compounds. Sulphides, selenium, silver, gold etc. There are also some compounds in my ancient notebooks which are unnamed but interesting. I have an old print made with one of these which certainly resists ferric chloride but it will be a bit of a bugger to recreate and then, only if the raw chemicals are still available.
One thing a can guarantee to produce though. The granddaddy of all smells. The missus might stop this project. She has no interest in returning to that ;)
One thing to keep in mind is that negative and positive photoresists work differently on shiny surfaces. I seem to recall (jeeze that was a long time ago) when we were making ICs, that positive resist was used for aluminum and platinum (negative resist was used for silicon oxide).
The trypophobes will hate me for this, but I'd like to drill an enclosure with a bunch of randomly scattered countersunk holes, glue a sheet of lighting gel to the inside and light the innards of the resulting pedal from the inside with a dim glowing light.
Alternatively, I'd like to paint an enclosure matte black with a bunch of very tiny planetarium star holes all over it, lit internally in white.
(Although I said that I would like to do these things, by posting it in this thread I am really trying to encourage someone else to make these things a reality. :icon_wink:)

Imagine that thing plugged into your pedal board :icon_lol:
We have had a couple of decades of electric toothbrushes powered by an internal NiMH battery that is charged by placing the toothbrush on a charging stand. The charging stand contains the primary of a transformer and the toothbrush contains the secondary with a rectifier to charge the battery. This would be great for a pedal - an AC charging stand and you remove the pedal from the stand to use it. Since there is a huge gap in the primary to secondary magnetic path, there is no possibility or saturating the transformer and since the pedal is removed from the charger and runs on an internal battery, there is no power supply hum when in use. No more ground loops from external power supplies.

While I appreciate the idea, the practicalities seem to have completely defeated the manufacturers of electric toothbrushes. Perhaps they're better at the "toothbrush" part than the "electric" part, or perhaps they're sly old types who have heard of "built in obsolescence"? No electric toothbrush I've ever owned has managed to stay charged for more than a dismally short period. I think they don't bother with a decent charging circuit and it shortens the battery life maybe? They seem ok when they're new, but six months in and it goes flat quicker than a smartphone watching youtube videos.
Perhaps with a decent charging circuit and lithium batteries it might work better. Who knows? Perhaps when we get the tech sorted, we can cut a deal with the toothbrush manufacturers!
I'd like to see somebody invent a mesh pocket for the bottom plate of hammond-style boxes. It would have a flexible mesh on one side and velcro on the other side. You could slip the bottom plate from an enclosure into the pocket and screw the plate back onto the enclosure and you would have a velcro surface that doesn't ruin the bottom of your pedal. The mesh side could be similar to this.

There's loads of examples with the flickery-light part, but I've never seen one with sound effects!
Here's just one example, with a ton of other extra features to boot:
https://hackaday.io/project/11796-avr-vs-pic-the-case-of-the-candle
The trouble with sound on stuff like this is that it's totally underwhelming because of the tiny size. I once designed a Doctor Who style sonic screwdriver sound chip for my young nephew. It generated a selection of interesting noises that could feasibly be opening, laser drilling, melting, etc etc if you had some imagination. The bit that stumped me was getting enough volume and sound quality out of something that would fit into a small hand-held device.
It might be nice if it didn't do anything until you stamp on the foot switch, whereupon it catches fire and smoke starts to billow out of it. I mean, we've all made pedals like that, right?...
Edit: a funny smell would be good too - that distinctive 'magic smoke' smell we all know and love.

Yes, fed to the output...I like it. So rather than the "expected" effect, you get something broken. Bonus points if you get a few bits of chopped and distorted input signal into the mix.

Yes, but I wouldn't want it to sound broken, per se. Perhaps it should work as expected but also sound subtly ablaze.
There's another band name someone could use: Subtly Ablaze. :icon_lol:
Ok, so you're thinking more of a "smoking hot fuzz" or a "steaming pile of distortion", whereas I was thinking more of a practical joke in pedal form..or perhaps a visual gag for the gigging guitarist. One way to get talked about would be to have your pedal catch fire during your solo, and then have to rapidly switch to something else. Of course, the audience wouldn't know this was actually a part of the show.
Still, I think either version is a brilliant idea. I'd love to have time to muck about with such a thing, but it seems a bit unlikely unfortunately.

Magic smoke with a funny smell? It sounds like you have found a use for the stash of selenium rectifiers I have. I remember blowing one of these on a December 15 of one year. I switched everything off, opened the window and went out to ride my bicycle for a couple of hours. No way I was going to keep that in even though it was cold and damp out. This would have been around 1964 give or take a year and the unit that blew was a General Electric television. Really nasty aroma.
It occurred to me that the technology in those smoking-replacement electronic vapers must be pretty similar to the model trains. But going into a vaping shop and asking them if they've got vaping liquid with the smell of magic smoke is likely to lead to something different from the desired result in this instance!

Cheap vape kit from which to harvest the vaporizer...

I used to love the smell of the smoke units in some of the Tri-ang trains I had as a kid. Seuthe I think is the maker of those (if I spelt it right).
The acrid smell from burning electrics I always assumed, was from the insulating varnish/lacquer like on coil windings which was Shellac based? Anyway, you can get that as button polish?
I seem to remember Lionel "smoke fluid" from the 60s to be light machine oil. I've heard model railroaders talk about using olive oil too.
Keep in mind that vaporizers are meant for very low duty cycle useage, but there are now numerous sources of DIY vaporizer rebuilding materials from which you can wind an appropriate heater for continuous duty.

not a black LED that lights up black when it's on ? (i.e. paint an LED and don't wire it up)
I would like to see a pedal labeled:
"My name is not important, and I'm not going to tell you what it is."
(my brother has my copy of the Hitchhikers Guide to the Galaxy, so I can't fully verify the quote)
Bonus points for adding a "Slartibartfast" label on the bottom or inside of the pedal.
Here's an easy one that I've always wanted to do but never could get around to it: Fuzz Face but built with TO-3 package power transistors and 1/2 watt resistors and 500V caps, with a clear cover and internal LED lighting so you can see the huge parts all mad science-y and stuff. Power transistors because they come in low hFE for ideal Fuzz Face tones. Bonus for huge knobs and a telegraph key or huge blade switch for the bypass.
Fuzz or booster pedals built with parts not made for linear/audio duty, like UJTs, SCRs, Triacs, Thyristors, etc.

A new member posted one about 6 months ago. It was a novel idea (but it was a bit finicky in terms of adjusting to get desired effect).

I always wanted to find some way of fusing the sound of my guitar with the sound of a dial up modem, think it would sound pretty far out but i lack the computer know how
That's easy. Just find a .wav file of a dialup modem sound, use an audio editor to fade it out, then load it as a reverb impulse into an IR Convolution plugin.
You know, that actually might make a fun experiment for this weekend... :icon_eek:
Stay tuned... :icon_twisted:

Idea: Build a pedal with a model train smoke generator inside. A glowing orange light plate (or orange lit knobs) would be good to add to this too. :icon_twisted:
Pass the smoke between an LED/Photoresistor pair to get true random modulation for a Phaser/Flanger/Chorus/Tremolo/whatever. The smoke would have to be pretty thick and/or dark to really work though...
Or two photoresistors for stereo... :o

I just searched the forum and YIPES there are quite a few threads about abusing phototransistors and optoisolators. If I weren't due for work in the morning, I'd have a lot of reading to do right now. As it is, it'll have to wait for the weekend. :icon_cool:

There were a few fakes as well :icon_mrgreen:,

OK, one more idea, and this comes from a combination of ideas and accidental discoveries that I'll explain in a second paragraph. The idea is:
A bass fuzz/distortion where you run the input through a high-pass filter that does a smooth transition from low to high (like an RIAA curve but tuned for bass frequencies instead of a "knee" at a certain frequency), do the fuzz/distortion/overdrive effect, then run the output through a low-pass filter that is the opposite of the input.
The idea is that it only distorts the top end, but on a smooth curve so you avoid the low-frequency 'fart bass' sound that you can normally get from simply plugging a bass into a distortion pedal, but retaining the sweet singing sustain of the higher harmonics, all from one box. This is akin to what most folks try to achieve with bi-amping, but the idea is to simply do it in one box.
Backstory: Many years ago, a friend of mine bought a Rickenbacker bass for quite cheap because something was wrong with the bridge pickup, and asked if I could fix it. I opened it up and found a very small value cap on the pickup output. I took that off and ran the output straight through. It sounded better, but still very thin and low output, so I concluded that he had a bad pickup. Well, I had it for about a month, so I played it fairly often because I figured it would be the only time I ever got to play a genuine Ricky. One day I had the idea to run the bass through an external phono preamp I had laying around, to at least boost the bass a bit. To my great surprise, it sounded like a DREAM. The perfect balance of growl and hum, even when playing finger-style. That got me thinking that maybe there was some heretofore-unseen Mojo going on in the frequency translation, and that's why I perceived guitar and bass as having more "presence" when listening to a recording from vinyl, as opposed to the same recording on tape or CD (first noticed on the song "Michelangelo's Penis" by Arsenal. I had both vinyl and tape; an A/B comparison confirmed what I thought I was hearing). So I got the idea to put a RIAA encoding curve on the front end of a distortion circuit and a reverse RIAA curve (like the "phono" input on most common stereo sets) on the back end might get me some sweet Mojo and set my sound apart from the then-current crop of dirt box clones. Later I realized this was also very similar to how Craig Anderton's "Vintage Effects De-Hisser" worked, but that's about as far as I ever got with the idea, so any takers are welcome to it. :icon_cool:

I played around with that idea in the early 90's. It has it's pros and cons. The Ibanez Modern Fusion MF5 (The "lady bug" pedals with the metal case) used that method. The Boss BD2 kinds of does that as well. The same idea inspired the Barber Drives. I have a vague memory of Barber using the RIAA curve as an example!
> a high-pass filter ....fuzz/distortion/overdrive effect, then ... low-pass filter
I'd done that. In a different field with different technology.
I needed talk-back in a BIG hall, only to the stage. I was studying directivity. I had space for a big cardboard horn. But no money. I used essentially a car-door speaker, but the horn and chamber boosted bass and cut treble. I took a $13 cassette player and high-passed the mike amp. If you talked soft, the complementary slopes made "flat" 600-3000Hz, what you need to communicate. If you talked loud, the consonants clipped before the vowels, so intelligibility stayed high and it did not hurt the ear.
Similar tricks were used in ham radio long ago. "Tone" was not a key thing, just "reach".

Note, the one thing missing from mine is the "rediculous hype" text.
What I have always dreamed of doing was to add white text with the same font to mine, but mine was going to simply read "half horse hype" instead.
Although I plan to live forever (so far so good)*, I don't think I'll achieve my dream personally, so I'm hoping someone else will create a "half horse hype" pedal to make my life more complete.
I did figure out the font, but I'll have to find the file with my draft version of the labeling to tell you what it is. I do remember that I had to mess with the kerning to get it just right.

I know this wouldn't quite give white lettering, but I have access to an industrial laser that I use for my artwork, I would be more than happy to engrave that on the box for you. I could get it all the way down to the bare aluminum which would give a nice silver-ish look.

Is it possible to switch the delay time of a PT2399 circuit on the fly between T and 2×T?
I have a crazy idea for a creepy tremoloish reverbish circuit with half-speed, octave-down repeats. It would consist of three parallel, time-staggered stages, each stage performing something like this:
Mute delay output.
Set delay time to T.
Unmute delay input.
After time T elapses,
Mute delay input,
Set delay time to 2×T
Unmute delay output.
After time 2×T elapses,
Repeat all of the above steps.
(Put more simply: Record some audio, play it back half speed, repeat.)
The second stage would do the same steps, but would start at time T.
The third stage would do the same steps, but would start at time 2T.
(Thus, at any given point in time, one of the stages is recording, and the other stages are somewhere in their half-speed playback.)
I should probably draw a timing diagram to better explain it.
Let's just ignore the edge effects of the switching for the time being. It's not at all meant to sound like a pure octave down circuit (glitchy is ok). :icon_wink:

Well, you would need to make it loud, obnoxious, and you don't necessarily need to link the input with the output... You can connect the output to an "alternative" input that sounds nothing like the original signal.

Resting Bitch Face is indeed a great Fuzz name. But the Orange Squeezer is already taken and what other color would you give the Muff Squeezer? Maybe white. Very white, almost translucent. Like alabaster. Well, as long as the enclosure is very stable and the circuit is genius. Needs a Covfefe knob, though.

I see two problems with this - colour matching [where to find that orange?] and the sculpting needed on the quiff. and as far as doing the hair on a boris - no.
It's really quite simple. You make Trump hair out of cotton candy, and you make Boris hair out of candy floss. :icon_wink:

Sockets that require no soldering/removal for quickly testing different values/parts. Just plug them in, test your parts then unplug the sockets. Granted you can just insert components loose in a plated through PCB but it's awkward and prone to lose contact.
I tried to make some using really tiny magnets but they were just too weak to hold.
I think I understand now. Something like these test points but with a socket instead of the wire loop?

Oxidize the outside of the wheel, then convert that into an oil-can delay. This has the advantage, since it is already on fire, that when you stomp on it, the little burning lozenges will come out and set the stage on fire. The steam helps humidify the room which can be handy during winter, and if you're lucky you might even be able to brew up a small cup of tea with the hot water.
For more variation in the modulation signal, add microswitches at various points around a "Mousetrap" game, which is nothing more than a plastic commercialization of concepts developed by Rube Goldberg.

The switches could link to servo motors on the steam engine's valves via Bluetooth and be controlled by "an app" because of course.
A Xerox cylinder delay might be a better item than an oil can delay. The original Xerox copiers had a selenium-coated drum where the selenium was charged from a power supply and where light hit it, it discharged. A receive electrode that almost touches but is actually a capacitive sensor (like the videodisk players) would read the signal but could be placed at an arbitrary angle (which could be variable) from the spot where the light hits. Less mess than an oil can.

Believe me, if you have ever smelled the stench of a selenium rectifier shorting out and catching fire, you don't want fire anywhere near selenium. I had this happen with a television one time when I was young. I remember it being December 15 of that year and I just unplugging the television (which was in my bedroom), opening the window and going out and riding my bicycle for two hours in the cold of December in Toronto. By the time I got back, it stunk slightly less.
The idea came to me because we spent a couple of years making X-ray sensors out of thin-film transistor arrays of the type you see in LCD displays with a selenium coating that is charged and then discharges where it is exposed. Since you can read the TFT array as a sensor, even though the dynamic range was quite small for each scan, successive scans could give you a dynamic range of 120 db. We had a similar program with an LCD covered with selenium where exposure to X-rays would discharge the LCD locally and you would get an image which you could scan successively to get a large dynamic range. It didn't hurt that the lead researcher on the LCD project was this gorgeous girl from Finland.
We were partnered with Agfa to do this. Why did a film company want to fund a competing technology? As they said, since the paperless office uses more paper than ever, they thought they could sell more film in the filmless medical X-ray lab. You can't argue with that reasoning.

I think it would be cool to use something like this LCD "light valve" as part of a bypass indication for a pedal, perhaps hiding and revealing a backlit waterslide decal, perhaps with a cutout opaque decal on top.

So, I got my little LCD shutter and breadboarded 2x LM317T circuits. I want the shutter to fade and it turns out this all happens between 0 - 1.9v
Unfortunately, the circuits I've got only drop to 1v so I'm getting my fade but with only a small turn of the pot.
Better way of controlling the voltage 0-2v?
(https://www.stallibrass.com/images/kas/LM317.jpg)
Could you stick a diode or two from the LCD ground to the true ground? E.g. Bump its ground up by a diode drop or two?
Then you'd need a voltage between 1.3V and 3.2V to control the LCD. That might be easier to manage.
Thanks Tom, elegant suggestion. Unfortunately, not effective on the panel but I did find an interesting effect. Depending on the diode, the shutter operated in slow motion. Not what I want for this project but a useful observation. Will have to get some sleep before I can work out why it's happening
It's probably "zero" current. Use a pot from a 1.9V source. Got 5V? Use 150k fixed and 100k pot series.
Thank you Paul, 0 to 1.89 :)

A few more ideas:
1) a pedal with a coin slot. Should probably be a bit crusher or something else retro-video-game-like. Up to you whether the coin slot is functional.
2) A pedal in a Rubik's Cube.
3) a clean blend pedal that combines a picture of Mr. Clean with the exposed metal skull and red eye of The Terminator.

Brings to mind this anecdote (https://www.diystompboxes.com/smfforum/index.php?topic=118986.msg1109463#msg1109463). ;)
Just had the following brain fart:
a delay with envelope controlled delay time, such that loud is fast an quiet is slow. The envelope follower would need to be set with a fast attack and very slow decay, so that a single short chord would be followed by several echos with the delay getting longer with each echo. Might be interestingly spacey. Has anyone tried that? Does it exist commercially? I'm cut off from my breadboard for the foreseeable future but if someone is bored, I'd really like to know how that sounds. Would probably benefit from a bit of distortion and high cut on the echos for a degraded tape echo simulation. Probably best implemented with a PT2399.
Cheers,
Andy
You would get some weird pitch shifting as you change the delay (might be quite unmusical), unless you are planning to use a bunch of delay chips set to different delay times and cycle between them.

Yes, the pitch would droop progressively in the echos and they will not be very harmonious with the original signal. That's what I meant by "interestingly spacey". Letting the echo output and feedback run through a band pass should help keeping it from producing too much sonic mayhem.
Andy
Envelope-controlled <insert effect>. Sounds like the kind of thing Rich would (may have) come up with.
Would work better if the times change in a stepped fashion to get the delays without a constant pitch sweep. Not necessarily from the envelope, but an attack triggered staircase LFO that steps each complete delay cycle. That means counting the VCO clocks of your PT2399 for something like 44000 or whatever it is and increasing the delay each count. The works might be best done in a small MCU with a 74HC counter reducing the PT2399 clock out rate to a suitable speed for the MCU. The Attack trigger could simply be the input signal getting high enough for a logic threshold into an MCU pin.
QuoteHas anyone tried that?

doesn't this pitch shift dynamically? and wouldn't it become some sort of wall of differently pitched notes randomly flying through each other while being pitch shifter differently for every repeat, essentially creating a harsh noise wall?

It would not be a very universal effect that would sound "good" with many different input signals, for sure. Finger picking country licks would certainly become a dissonant ruckus. Bot for certain slow material like short single notes with lots of space between, I could see that sounding interesting. Still dissonant but interesting. No?

"i do believe i have seen similar graphics on acid tabs, really makes you think."
I kept the terrible font arrangement from the original (most visible in their orientation and placement of the 'N' in "NOT"). The 'D' and 'R' are not quite right, but good enough.
This should hopefully link to a PDF file with the SVG (I was having difficulty with my plain old SVG save:
https://drive.google.com/file/d/1gn8nm0wpDtrI0DFgKo6pfddymZcDM7UQ/view?usp=drivesdk
It should look like this if it renders correctly:

If it doesn't render correctly, various bits of the text will likely appear black, oddly sized, etc. (I think it is an issue of text not properly converting to paths or something; there should ideally be no fonts required in the file)
Now, if someone uses this graphic for anything, it will make my miserable quarantined life more meaningful. :icon_razz:
I like the "Do Not Microwave" warning on the packet. For people who have access to a microwave and are bored enough due to quarantine to just put anything in it to see what happens.
"Oxygen Absorber" is also not the worst pedal name I've read all day.

Set them up so that they control two different loops with different effects chains and make the switching back and forth random, but with tap tempo, so it always switches in time, you just don't know how many counts it will take.
I had the idea earlier to build a messy glitchy pedal around a discreet Schmidt trigger that feeds into a adjustable low pass filter or some sort then follow it up with a gain stage to make up for the volume loss in the filtering.
I don't doubt someone has done this already but it might sound cool. Maybe I'll breadboard it later.

Tim Escobedo's "PWM" is cool. Uses a CMOS Schmitt trigger, and the varying pulse width gives a somewhat similar effect to modulating the cutoff frequency of a resonant filter.

basically, when the footswitch position is "off", or clean signal passes through, the clock enable of the CD4017 is LOW, and so it keeps counting, 1, 2, 3, 4, etc.
when the footswitch is turned on, the clock enable is now HIGH, and so the CD4017 stops counting, and is stuck to whatever value counted. Since the CD4017 has 10 out pins, and only 1 of them is connected to the JFET-switching-system-that-controls-something, the chances are 1/10... I think the chances are *too* slim... 1/5 i guess?

I was kind of hoping that it would be the supposedly legendary "Fug fuzz". I think Josh Scott had it mentioned to him in one of the fuzz history Youtubes he did. I asked bassist Leland Sklar on his Youtube channel if he could ask Danny Kortchmar about it, since Kortchmar briefly played in the Fugs along with fellow guitarist Kenny Pine and Sklar said he would pass my question along to Danny, since they are now bandmates. I also asked Kortchmar on one of his YT channel videos, but no one has gotten back to me. It may have been something unique, made specifically for one or both of them, or it may have simply been an existing early version of the Guild Foxey Lady or Big Muff Pi that the maker told them was unique. If one listens to the guitar solo on "The Garden is Open" from their
Tenderness Junction album, there is a really nice wooly violin-like overdrive sound on the guitar solo (and yes, I know there is an actual violin solo in the song as well) that might be the sound of the reputed device. It was over 50 years ago, so I'm not expecting a flawless recollection by anyone. But it would be nice to know that either it's not a real thing or was simply a BMP with a couple different cap values that someone made for the guys.
Sorry for the let down, Mark. I hope your quest eventually yields some useful info. I had sadly never heard of the Fugs before I made my silly suggestion.

The Fugs started in 1964 in New York City and were famous for doing raunchy songs like "Do You Like Boobs a Lot" and "Coca-Cola Douche". NYC didn't really have much more going for it until the Ramones.

While they were known for raunchy and political songs, they were also one of the more literate bands. If you were an Egyptologist or student of Greek and Roman philosophy or poetry, there would be much for you in their lyrics. Politically astute as well. You might also remember their song "CIA Man" played over the closing credits of the Coen Brothers film "Burn After Reading".
They were not known for guitar anthems, but Kenny Pine had some killer solos now and then. His solo in "Crystal Liason" (their satire of "psychedelic music") is a keeper, very much in the vein of some of Todd Rundgrens's more emotionally wrought solos.

it uses DSP to analyse which notes and schales you are playing and every mistake/wrong note gets a heavy dose of reverb and delay to make it stick out even more

We'll call it the Jazzer's Friend...
I used to live near a church. Throughout November and December, a group of five kids used to play Christmas carols on the steps in front of it. On trombones. Five trombones! Five 12-14 year-olds honking the same three carols over and over each weekend, somehow seeming to play in 27 different keys and 8.5 tempos at once. I wonder what you pedal idea would do with that.
Andy
Oh my. I can imagine the mother of all autocorrect pedals taking five inputs at once with pitch and tempo correction and going to an amplifier capable of drowning out five trombones.

I can't remember where, but I recall reading a story about a famous (unnamed) guitarist getting into an argument with a sound tech, insisting that they mic his amp... the sound tech eventually acquiesced, set up a mic in front of the cabinet, ran a cable backstage, and stuck the far end into a cantaloupe.
So, cantaloupe DI box, anyone?

A DI box with integrated looper? The Cantalouper Box? Brilliant! That would actually be kind of useful for looping in things like reverb or cabsim that you may not necessarily want to have on your stage sound but don't trust the FOH engineer to get right.
Not a pedal but it would be cool if there was a breadboard which detected component values and placements, you hook it up to a computer with USB and when you're happy with a circuit you upload it and boom, a schematic appears. Man that would be sweet.

I could imagine such a system being created using computer vision techniques. Could readily determine which holes parts go in as you add them, assuming you keep the leads short. Could probably add resistor color code reading too, but you'd have to manually tell it what cap values and ICs you are adding. Creating a netlist at the end would be the easy part, relatively speaking
i currently have no breadboard space available, but i have been thinking about a device i call the character box.
it's basically a cascading of a bunch of BJT or Jfet gainstages and resistive dividers. first boosting 3x then reducing 3x and boosting and reducing etc... this would impart nonlinearities of the devices used, without really clipping. it would be an extremely subtle effect and good noiseless devices should be used but i think it can make a clean guitar sound 'warmer' and fuller due to a bunch of added harmonic content.

i did a report on that once, carbon comp resistors and tantalum's have no discernable ''character'', no inductance, in nonlinearities and other stuff going on at lower voltages (up to 25V) ceramic caps however are microphonic, their capacitance lowers with rising differential voltage, they act symmetrical however. i don't think any of those features makes a difference in tone. nonlinear behavior in transistors do however impart a bunch of harmonic content.

Random thought of the day:
Where are all the pedals with googly eyes on them? Should be dozens of them. I haven't seen any. :icon_eek: :icon_razz:
Has anyone tried controlling a BBD flanger or delay via a theremin-like antenna controlled oscillator? I recently monkeyd around with a CD4069 based Schmitt Trigger oscillator and noticed that the frequency changes in some settings when I got my hand near some wires on the breadboard. So I checked and sure enough, there are theremin designs out there that use the exact same kind of oscillator but tuned to kHz instead of Hz. It seems feasible to use that effect fo control a BBD with a copper plate by foot, doesn't it? If I had any time at all, I'd get right to it but I don't. I'm sure I'm not the first to come up with that idea. Is there a commercial pedal that does that? Have you guys tried?

Andy

that sound better, 'vinyl mode' as the name, and some cheap LP cut out on top of the enclosure.
it won't have any gain or loss, so its not going to have any pots or switches.
i have been thinking and i am going to add inverting opamp gain stages to cascade the non linearity the same way, not back and forth.
subtile filtering a-la bbe sonic maximizer, but on the cheap, with some bridge-t filtering clipping to slightly reduce some mids and add sparkle and bottom
(which is what the BBE essentially does, its an expensive, subtle mid-scoop, that's why it works better on bass and fully mixed music than on guitar. using it life will make you fade in to the mix a little bit and stand out less....)

You could make the enclosure out of an old record that gets heat formed over a 1590B or 1590A or whatever fits the circuit! If you need one pot, it could go through the center hole.

No one? Or did this just get buried under the googly eyes?
Andy
Would it be different than having the rate controlled via expression pedal with a pot?
Very different. I don't mean "control the LFO via proximity sensor". I mean "use the proximity controlled HFO directly to control the delay time of the BBD". For a flanger that would mean not having an LFO at all and just controlling the swoosh directly by foot. I'd buy that.
Andy

yeah, this got buried by googly eyes, i haven't heard of it, neither have i tried it...
would be fun, but a treadle has a sturdy surface to put your foot on to and a pivot for referencing musscle memory against, but a theremin has no sturdy surface to stand on and nothing to reference muscle memory against, since you are always moving around on stage.
its fun while you're sitting on a chair, but i have gig-jammed with the Zvex Fuzz Probe once, and it wast't fun to use on stage, while moving and rocking out, it doesn't support you like a treadle does, and it doesn't give you a fixed point like a fuzz does...
cheers, Iain
edit:
i think a piezo pressure probe is easier. both in using it and designing a circuit that
reliably works for an LFO
QuoteFor a flanger that would mean not having an LFO at all and just controlling the swoosh directly by foot. I'd buy that.
Ah, yes. I have digital effects that do that. They end up sounding a little like a weird wah pedal or VCF, but like I said, it's just code, not actual delay circuitry. I agree, I'd buy one! If it's not a million bucks.
Quotea sturdy surface to put your foot on to and a pivot for referencing musscle memory
+1. Also where many guitarists pick up the bad habit of propping their right hands up with their pinky
Thought about this just before sleeping...
some kind of tilt sensor worn on your head, controlling an expression pedal?
For example, a wah. When you bob your head up and down, the sensor "detects" the angle of your head and sweeps the filter to that certain position...
If what I'm saying is understandable... :icon_lol:

Those thoughts have given me another idea:
How about a slowly retracting pull string actuator/timer for an effect, like the kind on talking toys?

Bonus points for multiple, pseudo-randomly chosen effects.
Or, how about an overdrive that is activated by a lawnmower pull string?

Love this idea. Bending down to pull the string might get old. But, a foot switch to trigger it might work. As if the string was already pulled and tapping the switch would be like simply releasing the string.
or, a vintage sowing machine style treadle, that makes a heavy disk turn round and round, this disk is then connected to a leslie style drum, to be placed in front on any old single speaker combo amp!!
i thought this was an appropriate place for re-posting this idea:

if anyone has taken a look at the CA3130, it has a CMOS output stage.
we can use pin 8 (strobe and compensation) as the output pin if we regard the (-) and (+) inputs as having switched places. we can then use the CMOS stage as a stand alone gain stage, without feedback, to utilize its soft-clipping nature, just like CMOS inverters!
of course we bias the ''first half'' of the opamp so the CMOS stage's output is in the correct operating range.

cheers!
EDIT: the CA3130 and 3160 are both eligible for this trick.
am currently experimenting with a bridge tee filter in the feedback loop from pin 8/strobe, to pin 3/non-inv.
it can really do that desert rock sound, especially if the guitar's volume is dialed back and the gain at 8, it really does that pushed mid-range "not quite fuzz, not quite distortion" tone, and a woolly overdrive when the gain knob is dialed back.
cheers
edit: the CA3130 really likes a 20pF to 1nF capacitor in between pin 8 and 1, despite the implemented feedback loop trick also coming off of pin 8.

The De-Fib Rillator, obviously.
Taking the best of a few other ideas here and voicing them over something entirely contrary, I came up with The BoJo.
It's a distortion with a subtle modulating effect blended into ambiguous re-timing that's entirely similar but not to be confused for extended delay.
It boasts an output of 2/4 timing but legally requires an input of 3/4 or greater.
Anything it considers a mistake it gates and replaces with sympathetic white noise.
If you play a jazz chord it'll halve the supply voltage and chortle to itself.
There's an optional 'sanction control' to adjust these features but you can't afford it.
The idea seemed plausible at first, though having riffed on it for a while it's quite apparent that no consumer would benefit from investing in one.

Carrier current pedals. These have the input and output modulated onto an RF carrier at separate frequencies.
No more ground loops since the radio frequencies are capacitively or inductively coupled to the DC source. Your stomp switch would select whether the input or the effect output would be modulated onto the output carrier. Or different pedals could be switched in or out via a radio pushbutton switch. No more plugs and cables other than the power leads. All signals would be present at different frequencies on the power supply and you just set up each device to receive the frequency corresponding to the pedal that is driving it.
