Re: Team 116 OI Adapter board

So that design restriction forced me to come up with the ribbon cable design, which I like a lot. My design ideas and plans went through many iterations before the board reached the form it is in now.

Among other things, I originally thought I was going to put some type of connector on each switch and pott, then I realized that was totally unnecessary, and would create unnecessary work later to prepare the switches and potts. Then I was going to use screw-terminal blocks, but that would require a screwdriver to use, and screws can loosen. Then I decided on the spring connector blocks, because they don't require tools, and they don't loosen.

Thanks for the tips on making PC boards. That could come in handy.

We thought about making our own PC boards, but it would require lots of jumper wires to achieve a single-sided design, and a double-sided design is a lot harder to do by hand. Also, there would have been 120 holes to drill in each board to mount all the parts (now down to 112 holes, with the removal of the LEDs, but still a lot of precision drilling).
Can't you just use a CNC mill with an itty-bitty drill bit?
