tiny tremoloOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO

Tiny 5-component flanger?

ha ha....close, but no cigar!!!!....

Mojo in a box?

[guitarmageddon]

etched my box today..and a few pcbs..

the yellow speed led is going in the middle of the  atomic symbol...on/off red leds will be three little outer nodes...i love an led or 4..ha ha...

Thats a beautiful etch, and the design is so appropriate for such a small curcuit.

@perrow: ahhhh we have a winner!..ive been sussed!....got any soundclips?.....

@ben: thanks for the nice comments man, yeah it is very appropriate....i do love an etch...

Very nice box and board Rob. 
I need to find the time to get mine boxed up. It's been sitting there waiting for a couple of weeks now.

[deadastronaut]

cheers manny, am boxing it today, i let my brother loose with the drill on it...and he drilled the top leds holes bigger than i wanted...b.......d...

so now have to use 5mm leds on top...arghhhhh...oh well thats what i get for leaving him to it...and i'll certainly know when its on /off etc...

the rate led is still 3mm yellow though...it works best..i tried red/green etc..but they stole a bit of depth.....

ive tested the pcb through my breadboard and all is fine...layout on page 24..very very verified...

Any suggestions on the specs for the LDR? I don't use them often enough to know what works best in this kind of circuit. If I'm searching properly, Mouser doesn't carry any. I found some while looking at Futurlec, but wasn't sure which to order:

I'm excited to get this built. It looks like a really great, simple project. Thanks in advance!

@perrow: ahhhh we have a winner!..ive been sussed!....got any soundclips?.....

Can't take credit for it, it's frequencycentrals design, so you'll have to ask him for soundclips.

@Chris: I ordered from futurlec a week or so ago and went with "hell, for $0.25 each I'll order an array of ldr's and try 'em out". I don't know your budget constraints, but you might give that option some thought.

Perrow - That is likely what I'm going to do. The reason I asked was that I don't play guitar and was scouting around for a DIY tremolo for my brother (the recipient of many of my effects pedal related gifts). Thus, I'm unlikely to notice if it is as good as it could be.

Thanks for the help though! I really appreciate how helpful this forum's community is. So helpful, that looking and searching has managed to answer most all of my questions without even having to ask. Keep doing what you're doing.

This may have been answered earlier and I missed it, but why a 3mm LED for the rate indicator as opposed to 5mm?  Is it due to ma draw?  If so, wouldn't a low ma 5mm be just fine?  Mouser has them down to 1ma.

All of them should work with dark resistances > 1MΩ, but I think the light resistance determines the depth of the effect. You can always get one with lower light resistance and put it in series with a resistor or trimmer to fine-tune

built and done. behaves really well....doing video demo at the moment...

got to shorten the pot shafts...too long for the knobs..

[deadastronaut]

heres the demo video guys...

edit: now ive sorted this i may go back and revisit the dual tremolo.stereo panner again....hmmmm...sounded great on lead..moving around the mix..

Wow.


Just WOW !


I think I fell in love with this pedal....

[deadastronaut]

cheers man, yeah i love it.........

Quick question, how does this work? The input and the output are connected so wouldn't it just bypass your whole circuit? I think i'm missing some sort of valuable information and i'm probably going to look like an idiot .
Also can i request a non populated layout please. thank you.

The input and output are connected, but the LDR shunts signal to ground at a rate determined by the 555 LFO speed. Think of turning a volume knob up and down really fast.

what patrick said^

i'll try and get round to it soon ok...busy today.  or download diylc and copy it...ok.

its very easy to knock one up on vero for a quickie....

This is my version of the "final" design. Unverified as always
