About getting the pcb:
I used batchpcb to make the board, but I hadn't set up the option where people can buy my board yet. I'll see if I can do that okay? I can't make any promises though. (my parents might not let me)
The parts are:
6 595 shift registers
2 2803 sink drivers
32 330ohm resistors (could be smaller)
6 16 pin sockets, with built in capacitor (from electronics goldmine)
2 18 pin sockets
Arduino stackable headers (I got 4 8pin ones, then cut them.)
Optional:
Right angle headers
2 jumpers/shunts (to select either manual control of the enable and clear pins of the 595s)
If you don't want this option, just solder a wire between the middle and outer connections.
About my age:
Yep, I am only 13. (14 soon this summer)
Ps I haven't gotten a chance to film the sequencer, but I have made an awesome cardboard and hot glue enclosure! I really like the finished product, it really gives a made-this-myself feel.
Pps I haven't filmed it yet because I don't have a FireWire cable to connect my dads video camera, and I can't hold it up to my built in iSight camera like I did in the first video.
