Hollow Earth v2?

Alright.....

I posted the video sample and details of that Hollow Earth pedal I built a couple weeks ago on about 5 forums. It went slightly viral on a few others thanks to a few users. Anyways, interest in it has been a little overwhelming! So much so that I've convinced myself that I should build a batch of revisions of this to spread around.

Things I'd like to add/change:
-Eight to ten presets, all overwritable with your own shapes
(with LED digit display)
-Expression-in for the shaping
-Expression-out to "shape" other effects
-Rugged footswitch for record instead of the flimsy button
-Random mode
-Triggered envelope mode
-Sample input as waveshape
(the last one is a biiiig maybe)

After a 10-day break from this stuff to play jams/gigs, I started tinkering again. I got random mode mostly working, and I've started the preset saving bit. 8 pin DIP 24LC eeproms are a wonder!

    I came across the video for this by accident and am very happy I did! I would love to know if/when the Waveshape LFO would be available.

    unfortunatelly schematics won't do you much good as most of the work is done by the microprocessor, in code. do you have access to an AVR programmer and Bascom?

    Unfortunately no, but I find this interesting kind of stomp and I could buy a programmer for the chip if necessary.
