This is my hard clipping diode custom design.  I played with a tl072 and clipping diodes until I liked the result.  This is its second enclosure. I call it the screaming monkey.  The eyes are the clipping diodes (yellow leds)  and lights up when it distorts.

LED's make good (buy leaky) photodiodes, so it would be interesting to see if the clipping level changes with light level or if strobe lights can modulate the clipping.  Nice looking unit!

Interesting.  I wasn't aware of that fact.  I'll do some tests with this.  Could be interesting to have strobe-induced clipping...  Lol.


Thanks for the compliment.  This sticker is why I re-housed the pedal: I just had to use them leds for eyes on the mad monkey!

I'll add some text in the future too.

I used to be in a company that manufactured avionics and we were having a difficult time trying to get infrared touch panels to work in direct sunlight.  Someone suggested we try green LED's to get away from the huge amount of infrared at altitude.  We built a touch panel with green LED emitters and receivers and green optical filters but we found the leakage current was high and varied from unit to unit and also increased with temperature to the extent that it masked the effect of illuminating it with green light.  Interesting idea and it did function in a narrow range of temperatures, but we never got it to work reliably over the full military temperature range and ambient light.

Have fun testing over temperature and with various amounts of ambient light - you might be able to induce interesting effects with a strobe light.

LED's have the same problem as germanium diodes and transistors - there is no passivation layer to trap the active semiconductor below the surface, away from surface leakage currents caused by contamination.  In the ordinary use of an LED, this does not matter.  You can grow an oxide on silicon that is impervious, so silicon leakage is very low.  Germanium oxide is conductive, so you are out of luck there.

My (quick)  reading on the matter seems to point that leds have narrowband photodetection.  I think the yellow ones would mainly read yellow light.

Here's my germanium fuzz face,  where the transistors are pulled from used old avionics equipment I got from a surplus a while back.

I don't have a stomp switch handy,  so I figure I could use the switch guard instead,  goes with the avionic-ness of the effect

it's got a nose like a proboscis monkey. or jimmy durante.

Love everything about it

I came up with a better (to me) OCD so I swapped the board out of my previous build for the new improved "Super Cod"
Wanna see it happen? Well, too bad cause yer gonna 

[Hatredman]

Not the right topic, but any soundclips?

What are de differences between this and the previous one?

[Ben Lyman]

not much different than my old "Super Cod"
This one has a 1n914, 1n270 and a 1nF cap instead of 2 1n4148's and a 10nF (or Mosfets) in the clipping section (or whatever you call that space between opamps)
I also scaled down the tone control to be more useable, no "mud to ice pick" range

My last build, etched enclosure, I suck at taking pictures.

Very cool, I like to use eyelet boards where possible also.

I've always been a huge fan of your work good sir. This pedal is no exception

[tubelectron]

Again and again, I always see amazing etched or painted finishing in that thread... That I can only admire, being still unable to achieve them ! Congratulations  ...

When not using old various equipment plates for odd-retro looks, I stick to laser engraved and cut plates, here on a clear grey box :





A+!

Some recent builds:

1) A stock Red LLama in a diy first-trail trapezium enclosure.





2) The Butt-Weiser: a jfet buf 'n boost circuit with toneknob to bleed off some bass.





Finish is just office-paper with clear plastic foil (the kind you use to protect the cover off a book) that is glued on the enclosure.
Kinda like making your own stickers.
The glue may be a problem. It tends to bubble the paper.

Use 3M spray adhesive and lacquer instead...
