tiny tremoloOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO

[Der Groovemeister]

My voltages are about the same. Pot in place of the 2.2K: still ticks at any voltage. Removed ldr: still ticking. Hi bright led: still ticking

[deadastronaut]

thats weird man......i dont know what to suggest... if the voltages are the same etc..

i dont know how it could still tick without the ldr either......


so how are you wiring the audio without an ldr?...

[Der Groovemeister]

Without the ldr its straight thru. in to out.

[deadastronaut]

@servaas, have you tried this on breadboard first...?

i just dont get why that is....ive been trying my best to find a way to get mine to tick..ironically...but it only will with the higher voltage...hmmmm.......

if i dont make a connection to ground with the other leg of the ldr it ticks like mad....is it being grounded..silly question i know!..

all my grounds are tied together...power and signal...


has anyone else got this problem...i'd be interested to know.......


ive even just tried this circuit..its a fade in /out led circuit, i rigged up the led/ldr and i added the essential 2.2k and it doesnt tick either....

have you a clear picture of it...just out of curiosity?..

[pazuzu]

@pazuzu..man that was a while back now!...i remember someone on here sending me an email, saying that one of my projects were being discussed...and would i care to join in..so i did!..and have been on here ever since.. .

you're my favorite member.

seriously though, someone needs to give you an award for this tremolo. it's epic on my breadboard. also really cool with the beginner boost built right into the circuit.

[Der Groovemeister]

I don't have a breadboard. I know: silly!
I built it on vero from the last layout you posted. I always use star ground. Just got an idea: what if i try shielded signal cables? I'll try that.
Picture maybe later...

[deadastronaut]

@pazuzu...thanks man!..  does your tick at all on your bboard?..



@servaas, yep invest in a breadboard,2 jacks and a dc socket and fix em permanently to ya board...i have 3 large boards setup this way for different projects..and tinkering...i couldnt get by without them!.

i bread everything before i commit to building...saves money and time and if you like it box it..if ya dont pull it all off...

i dont know about shielded wiring on this, but it may help,.....btw out of curiosity...what guitar are you using?..single coils...humbuckers...i'm using an ibanez rg470 humbuckers!..




yellow tip in/ blue tip out....

i like this setup i can use my board straight away as a pedal...i should put a bypass switch in there too ideally to hear unity etc..., but i never get round to it..



@all.

ive been working on a fading led version with a wah circuit, so we get a sine wave too...more flowing etc...just add 1x2n3904...

the basic ts555 fader circuit is this..

http://dl.dropbox.com/u/7464107/led%20fader.pdf

heres a soundclip of the fader tremolo..no depth control just speed...would be a nice tiny addition to any pedal with just one knob..very smooth sweep..

i turned the gain on full on my mixer at the end of the clip  so you can hear that it doesn't click..

Very very nice Rob! 
I'll be building this or something very like it next week as soon as the parts arrive.
I may even build it into an old wah shell and make the speed foot controlled.
It won't be tiny any more but still

[deadastronaut]

sounds like a  cool idea!..

i wish i had an old empty wah case to play about with...

http://dl.dropbox.com/u/7464107/led%20fader.pdf

I've been looking for something just like this that can fade in and out. Good find Rob! 

[deadastronaut]

yeah its a great little circuit...less choppy etc...lots of possibilities for it...

Yep, it's sat on my breadboard now waiting to be abused!   

[deadastronaut]

ha ha,...abuse away.....

[vendettav]

so what LDR should i get>?

[deadastronaut]

get one that has 1MEG dark resistance...should be ok..

[deadastronaut]

the tiny trem seems like is going to have be slightly bigger...

gurner warned about this a while back..(i know)......its a great trem..but now i'm getting fussy...

when the speed is increased the volume drops....especially when distorted....arghhhhhhhhhhhhhh.....

heres a soundclip....full depth...just adjusting speed ok...nothing else..

http://dl.dropbox.com/u/7464107/voltest.wav

hmmmm....looks like theres going to have to be some kind of buffer/boost  or 'compensator' circuit in there.....arghhhhhhhhhhhhh


edit:..thinking about it...(over dinner)...why not just whack a boost in there and have it as a boost pedal too... switchable...2 birds with one stone....and 2 pedals in one....thinking aloud!...hmmmm

It doesn't seem to drop the volume that much.  Some, sure, but not too badly.  Considering the simplicity of the circuit, I'd leave it as is really.

[deadastronaut]

yeah joe i agree, its great..especially on clean stuff..nice n subtle..... but its very noticable with pre dirt......and i quite like the fast hard stutter too..but needs just a bit more poke to it......hmmmm... i'll have a think.

[artifus]

how about just a resistor in the bypassed signal to compensate?

*edit* don't let it get much bigger - minimal modular building blocks are the way to go. also, if you like dirt and stutter have you played with 4093 cmos gated fuzz? 386 driving a 4093 with one cap and one pot. like this.

[mrsuspend]

How about a simple boost and a dual pot simultaneously raising the volume as the speed increases?
