@perrow.. why the pin 4 connection?...

I misread Adriano's post and haven't had time to correct myself. Pin 4 of the IC needs to be either removed or at least bent so it's not connected. I've updated the image with a note about this. Reload if you don't see it.

On the other hand, I fixed it in ... [drumroll] ... the next version :) Even moved the rate led ground to the edge of the board.

i used a standard 5mm red led with a 5k ldr....and i get fast trem out of it...

How do I measure an LDR? Since their resistance is dependent on light. Thanks

now thats a great question....i measured mine in indoor daylight no direct sun.....i didnt try it in the dark..hmmm..
but i got 4.5k..so i figured it was a 5k..but!.....

i just measured the diy vactoral and it read 80k now that its wrapped in shrink...so i guess it must be 100k or something..not sure on the
tolerance of these though!...!!!!my bet is it is 100k...

I think with some searching (admittedly this subject may be a broad search and could take a while) I read a thread a few months back by R.G. or someone of simmilar experience explaining how to measure them accuratley... have a check atleast.

Oh and by the way, really nice design, I love 2 knob designs, now it just needs a toggle switch to do something  :icon_mrgreen: that's my favourite kind of pedal layout.

cheers scruffie..yeah i'll take  look...

yeah id like a simple toggle on it...just to on/off the depth !...and get choppy.

I just wired this thing up, but i think i have a short somewhere ,because after flickering then getting very bright, i think i fried my led... :icon_surprised:
oh ,well- i'm gonna try and get it working tonight and i'll report back...
i saw your tiny panner and i may have to try that as well... just hope i didn't kill my chip, but the 555 i have is rated for up to 18v so i think it should be fine..

You mean, like the switch for "in line"/"bleed" :)

I leave it for someone else to show a way to use the depth pot for both modes, cause I can't see a way. Just maybe there's a way to switch the pot between bleed controller and parallel with the ldr (I think that was deemed as good alternative for depth, wasn't it?).

hi gil, yeah the 555 should be fine, yep led's they are easy to pop..ha ha..
had no problems with mine though!.im using a 9v battery at the moment...havent tried it on my psu...!!!!!

@pelle. yeah i too was looking at having a simple toggle on the depth, rather than a stomp, just my preference!
cool layout you've done though, nice one!..

hi paully.
light dependant resistor...shine light in it and it reacts...so the led flashes into it..ok.
same as this..

this one sounds great too!!

@adriano..sorry forgot about that one too!. :icon_redface:...did you still have a clicking noise with it?..

@searoad. checkout youtube ' how to build a synth'...its pretty basic but i cant remember the details of it at the moment ok...
its a '74hc14 chip!...ldr and a pot..the light theremin!.

The next one on the coming week...I have to say I experienced some volume loss with the TT - maybe we can say it's better to boost the signal somehow...

did it lose level when boxed with a switch?....

a buffer was suggested early on, on this...maybe just a single transistor boost  stage ...

before or after though?..or both...what would you suggest?..or even a dual opamp!!!...hmmmm...

I would say tack on an lpb at the end. Simple, low parts count, good gain recovery.
