its an Harmonic Perculator

Good work.

Which schematic did you use and which transistors?

Its the latest revision schematic drawn by various board members here. The transistors are OC76, 2N1613 and the diodes are OA5.

oh and i just tested it, delicious fuzz

Here's my latest project.  It's milled on a CNC mill from a block of aluminum.  Spent 10 minutes on the buffing wheel with it and I think it's going to turn out better than anticipated!  This will house a BMP with switchable transistors.  I've like it both with 5089's and with 3904's so I'm adding a 4-way rotary switch.  Not sure what I'll use the other 2 positions for yet.  Maybe input caps, unless I run across a better idea....

Well...I finally did it...I went and screwed it up!    I was too impatient to wait and bring it in to work tonight to drill it on the bridgeport. I attempted it with my 1/2" hand drill....One of the LED holes walked on me.  Still gonna look sweet though!  I'll have to come up with something to distract the eye away....lol  Pics tomorrow of the finished project!  I decided against the muff.  I just don't think I'll use it.  Instead I'm doing a double pedal with a '77 OD-250 and a Gus NPN boost.  I've been using that combo quite a bit lately and it just seemed to make sense to me...   

Coming soon.....the SNAKE EYED BEAVER OVERDRIVE!

It's my highly modified BSIABII. You can hear it here.

very very nice sound  .... any chance of getting the modified value ?

Some gut shots this time. A further developing of idea presented in this tread.
An LDR based tremolo with tap tempo, 4 waveforms and "beat divider" function - the actual trem rate can be 1,2,4 or 8x the tapped period.

And here, still in debugging/tweaking stage, a 4 stage PWM tap tempo phaser:

Very impressive!
Do post some photos when it's finished and some soundclips please!

[birt]

that looks really neat. congrats

The Trem proto is almost ready:

during the LFO tests i recorded a sample showing how does the different waveform sound, a sine, hypertriangular, triangle and square:
LFO sample
There is a DIN5 socket, i called it "Tap Link". It's a feature allowing to link more pedals together and synchronize the tempo in all of them. Only the "root" tempo is synchronized, so each pedal can have its own Beat Divider setting, for example, a trem runs 4x a tapped tempo, and phasing 2 x slower.
This link is optically isolated to get rid of ground loops, something similar to midi interface sending only "taps" between pedals.

bad news about the drill walking.....

like you I have machines at work I can do my machining on, ranging from a simple bridgeport to 5-axis CNC mills but to avoid the "walking 1/2" drill" problem follow these basic tips, its simple bench fitting skills.  Mark out hole, centre punch it, this is important.  centre drill it,  pilot say with a 1/4" drill then drill full size.  you should be able to get a hole within 0.005"-0.010" of desired position and it wont skate across the job.  Sorry if thats sucking eggs for you but it might help others.  even using a pillar drill I would at least punch and spot the hole first

i had a couple of non stomp circuits i was going to be using frequently and i had bought a bunch of old microsoft mice to make footswitches out of, so i built them into the mice:

  No Rat's on your pedalboard?

nope only mice

The Snakeyed Beaver Overdrive is done.  Or as done as it's going to get.  (Almost...have to get more decal stock and label the knobs properly)   My second attempt at waterslide decals didn't turn out any better than the first...But heck....the art doesn't make it sound any better right? (I'll just keep telling myself that)  The light reflecting on the polished enclosure isn't helping matters any.  Laying flat in a normally lit room it looks quite a bit better.

I wanted to try and etch this enclosure, but I'm still experimenting with laser printer/ photo paper transfers.  I'm getting there, but it still needs work yet.

This is a '77 OD-250 on the left and a Gus Smalley NPN Booster on the right.  Hooked up in series.  It works better than I'd hoped!  The Booster puts the OD250 right over the top just where it needs to be for soloing.

My drill walking screwup yesterday was fixed last night.  I made a press fit brass bushing, milled a 1/2" hole where my screw up was (in the right location this time!) and pressed in the bushing.  Fit my LED bezel and LED into it and epoxied.  Turned out better than I thought it would.


Anyways...here it is in all it's nasty newbie glory!   I'll hopefully have some sound clips after our gig tomorrow night.  We're doing a live recording for a demo.

  Some gut shots this time.
  You betcha- takes alotta guts to try pulling off a complex stunt like that !
  A further developing of idea presented in this tread.
  looks like that kinda stuff's really good for you, moderation aside.
  An LDR based tremolo with tap tempo, 4 waveforms and "beat divider" function - the actual trem rate can be 1,2,4 or 8x the tapped period.
  What a handy thing to take along for your LFO to play with ! [looks tricky.
  Kudos Builder Mahn. Just viewing what's on that board [top-mount OA's with legs wired 'quick-hot' it looks like, a packed situation on double sided board...
  I would hate to run out of oil or take a wrong turn on a long trip like that, it looks like you had to design then try some of your own new charts, it'd take some serious study to become a trustworthy guide for that adventure.

  DIN5 it, Uber Cool concept, we expect to hear various sound samples/applications.
  Optically Isolated?

Thank you
This is not the first proto I had the analog part tested in previous versions, then i wrote a completely new code for the uC including tap tempo and all that stuff.
Recently i  decided to take away the four waveforms from the trem, the log(sin) sounds the best to my ear. Instead of four different waves the pot will allow to change the bit resolution of the LFO wave. From a pure hypertriangular, through more stepped wave to square/impulse. I think it will be more interesting and usable.

Optically Isolated?

I used an optocoupler, each tap taps the tempo in the pedal and additionally turns on the diode in the optocoupler in other pedals. That way it works like tapping the tempo in all pedals at the same time. I wanted not to add another ground loop via tap-link cables, so the connections are isolated.

Ok, here's another proto from the world between analog and digital:
Bit Crusher
knobs from the left are:
Output level
Telephone filter - from bandpass telephone filter to full range
Resolution - actually regulates the ADC speed, gives a  ring modulation type sounds
Crush - amount of the bit mess in sample.





But i think the SOUND SAMPLE is more interesting
Gradually, a Crush parameter is increased, then the telephone filter is at max, at the end the Resolution goes doooowwwnnnn...

dont like paint jobs? yes?

[moro]

I've had these Luciboxes for a while and I finally got around to putting effects in them.

Beautiful. Where are the knobs on the CE2 from?

[darron]

hipshot has some knobs like that, as well as some other REALLY cool products. browse their site is you haven't seen them: http://www.hipshotproducts.com/cart.php?m=product_list&c=25

they are cheaper on this site which also has cool stuff: http://www.guitarpartsresource.com/guitarknobs_hipshot.htm

[ambulancevoice]

greatest, most amazing like paintjobs ever
my jaw litterally dropped when i viddied them, seriously
