I drew one up that's a bit smaller than their vero (34x20) but that's still pretty huge! IMO, the wiring is much more organized (all on the two ends of the vero). mine also includes a 7660S voltage inverter to get the needed + & -9V. I also made mine with the depth and bias controls externally. I just need to go over it a few more times to triple check everything before i build it.
I just updated the layout, and built it so it's now verified. I was also able to make it a little smaller at 32 x 20 with no stand up resistors (it does have a zillion cuts and links though at 67 cuts and 35 links!)
if you copied the one that I posted earlier today, disregard it and use this newest one.
and nope. the ticking is barely noticeable, if at all. If you use TL061's for the LFO (IC1, IC2) it even has less ticking than the LM741's did, but they weren't bad at all.
having a scope it makes calibrating the shape control a lot easier.
I also made the speed control able to go a lot slower by replacing the 470n with two 1u's in parallel:
You could even add a switch with 470nF and 2uF caps.
I'll definitely build one.
I want to make a layout for Mictester version and if it comes out smaller enough I'll build one and compare it.
I've finished Mictester version and it works.
I've found some 2n3819 and I compare them to the 2n5457 & MPF102.
The 2n5457 were doing nothing and the MPF102 was the closest one.
I've used the 2n3819 at the end cause it sounded different.
I've done a new layout with the right pinout
