I'm was going to be using the DS18B20. It's got 3 legs on it 1 of which is a ground that goes to the Arduino's ground plane. I though maybe I could share that ground too but by Chris' schematic the fan grounds all go through either a 10K resistor or through a 2N3904 transistor and I wasn't sure if that would work...
Which actually brought me to another question about that 10K resistor. All I have here is a huge 3W10K resistor, will that still work in that fan circuit?

Lol, ya the original was a bit small. I got my ampehol connectors in and a buddy of mine is a mechanic who works for highways has a crimper so I should be good to go. Although because the pins are removable, I think I can actually solder my wires on.
How's this pic for size:

Wow I missed a lot here.... sorry work has been stupid the last 6 weeks.
Looks like you've made some great progress. You can use BC549, that's what I'm using as well. Just remember that the pin orientation (collector, base, emitter) is different on the 2N3904 than the bc549/547.

Yeah... that pic was small. I ended up emailing it to Dom shortly after.

Hey, there he is!
Ya I did some googling about the differences between them all and found a page there that said the pins were reversed so I hooked them up right, whew. I'm not finished wiring that all up, but am working on it. Mounting it all on a breadboard. I'm pretty excited about the amphenol connectors, they look awesome and will work great! Thanks for suggesting them Chris and to Mike and Scubasteve for the input for helping make my decision.

Nice to see how everything is coming together! There's still a few things I would like to do to mine, but it's hard to find the time right now.
