Anyone done a layout for Tim E's Simple Square Wave Shaper?

PCB, Vero, or perf, I'll take what I can get. I've got three weeks before I head OS for a holiday and I wanted to get a few things finished and out of the way. (Got to clean my building room for the house sitter). I've wanted to make this for a long time so if anyone can help me build it faster it would be appreciated.
Cheers.
Any reports on Chords through this thing? I remember reading a build report saying it was actually quite friendly towards them. My ukelele might have a new friend.

There's a layout in my site. I built it some time ago, but didn't had much time to play with it, since it was built to a friend.

This is one of my absolute favorite circuits, and I play it often. It loves chords, and has sustain for a week! Look in "Search" for "Tim Escobedo's Simple Square Wave Shaper" with my handle, for my review. It sounds so good, that my wife even likes it!

Want some REAL fun?

The SWS produces different tones by adjusting the ramp up and ramp-down time of the square wave.  If you replace both of the 500k attack/decay pots with a 500k foot-controlled pot (with 270k fixed resistors on each end), you can work it like a duty-cycle or PWM control

If you need your feet for other stuff, replace one of the pots with a photocell and an LFO driving an LED for automatic PWM-type sweep.

Thanks guys. I got it up and running on perf last night using marcos' layout. Yeah it loves the chords, so the uke loves it. I was thinking of replacing the 500k pots with either an envelope, or lfo controled vactrol. Or both. The uglyface 386 envelope control should do it. Its a bit rough and ready but it works a treat in the uglyface.
But I think I'll have to leave it till I get back from Japan. Now its working I can't stop playing with it, mods will have to wait. I plan on rehousing this in a big box (just a plastic one at the moment) and adding some filtering and maybe a bypassable octave section from the RM octavia. This could be the circuit I've been waiting for to add all those cookbook bits to. I think my wife will like this one too!

Great that you liked it. Tim circuits are very cool.
