[nonpedal] Baby Ten Sequencer
« on: May 21, 2014, 02:46:56 AM »


Ten step sequencer, selectable from 1 to 10 steps, with reset in, clock in, and manual step and reset. CV out, and gate out :) Had to do some farting about with the Reset input circuitry.



Mechanically, this one wound up being a bloody pig. I spent more time getting the pots and switches on and then wiring it up than I did soldering resistors in. The board is backwards because I forgot to mirror my drill holes for the faceplate, so it was either drill the very expensive faceplate, or mount everything Lovetone style.

Not to mention everything is too damn close together. The pot markings are because I'm out of good 1900H knobs. Almost out of 3.5mm sockets, too.



This is what the other side of the board is like. I pinched the IC's for my final version, and didn't socket the transistors on the final one either (no vertical headroom.)

Still, everything is a learning experience! Now I know for the next board :)

Very cool Alan. I also did a PCB layout for this sequencer (although mine isn't eurorack mounted).

Have you seen this: http://www.arturia.com/evolution/en/products/BeatStep/intro.html

Gives you a step sequencer and will also do Midi-CV conversion. It's eurorack compatible too.

Looks sick Alan!  I gotta build something like that.

looks funky

just out of interest, does everything now work in reverse due to the flippage?
