Where to buy "KeyWiz"?

Yeah,  you're right, too early in the morning.  56 inputs, what was I thinking.  I hit post, and then immediately realized my error.  At least it wasn't a work e-mail to my boss :).  I will e-mail you in a few minutes with the layout.  The layout is not that bad for mame actually.  But the price is right.

Dougmeister:
Ok.  Finally ready to order, but...

Where do I buy 22 gauge wire for this project?  How much do I buy?  Is 22 ga the right size?

SirPeale:
LOL...I'll have some more the same time I get the disconnects.

Dougmeister:
Timing is half of life, isn't it?

I'll just scrounge some wire up around here.  Thanks anyway!

Where - Someone posted a link on the forum for a reasonable website for this.  Not sure if GGG has it.  Bob Roberts does.  www.allelectronics.com used to be I think they discontinued it.  Radio Shack if all else fails.

Amount - You need twice (power and ground) the distance from each switch to the encoder.  (A little less than twice because you can "chain" the ground wires from one switch to the next in a loop).  Plus extra for slack/mistakes, etc.

Size - Stranded is usually preferred over solid, but either will work.  Also in case you don't know lower (numerical gage is thicker wire).  Look under your car - Internal dash wiring is 18-22 gauge - The wire coming off the alternator is probably 12-14 gage - The wires off the batter are probably 2-4 Gauge.  22-Gauge is usually picked because it's thick enough to be easy to work with but thin enough to be inexpensive.  20 or 18 is fine as well if you can't find 22.  Lots of people use DB25's for swappable panels and the internal wire for that is usually 28 or 32 gauge.  It works (especially going to screw terminal blocks), but I wouldn't want to put crimp connectors on it if I could avoid it.  OTOH, you could wire your panel with 10-gauge wire, but it would be expensive, less flexible to bend around corners, and wouldn't gain you anything (overkill).
