"It's a sequencer based on the Seku by Mauno Tuominen (link).
The whole thing started of as an idea to build a simple gate sequencer using only CMOS. I thought that by using just 2 4017 and some logic I could get it all to work. But after some trial and error - that just resulted in failure. I gave it up.. (The basic problem was that I never got it to reset at the right step. It was either to early or to late..) ..and decided to build the Seku instead.
I'm not sure I'm gonna get it all to work. But the LEDs light up fine (except for LED 6 and 16 which I have the wrong way around..). I'm gonna try the CV portion out tomorrow, and I hope I'm able to finish the gates aswell."
