Edit Reason: Bolded Smoke Test

Electronics I
Where's my damned small screwdrivers?
So, After completing the physical assembly of the OneUP, I had to start the Electronics.
A little bit of background: I had pulled the power supply out of the kit sometime during my year hiatus, and wired up the 3-prong plug and plugged it into a socket, and then ran the multimeter across each of the two rails. Sure enough, they each showed 12V.
So, I got home with this printer, and the EPLATE (as it is called in the BOM, the Instructions refer to it as EBOTTOM). I had left the power supply at home, and so could not assemble it at build night.
I bolted down the power supply and RAMPS 1.4 board, as directed in the instructions. Then, I attached the FANBRACKET to the fan, and installed that sub-asembly.
This is when the lull between my finishing the OneUp physical construction and completing the project happened. First, I could not find my small screwdrivers. I did have a pretty small screwdriver in my car, but I was dealing with multiple crises with that car, and it was at the shop. Also sandwiched in there is a trip that I took. I am several entries behind in my build logs (at the time I write this, I have not published the Chassis Sub-Assembly and Final Assembly log entry, yet. Although it is written. I write the entries in a text editor before I ever log on to fabric8r.com.
Anyway, I eventually got my car back, and I use the small screwdriver in there to finish wiring up the power supply with the RAMPS board.
The fan had a really long wire on it, terminating in a plug. The instructions had me directly wire the thing to the power supply. Out came the wire cutters. I shortened up the fan sub-assembly's wire and removed the plug with one snip. Then some splitting, and stripping, and I was ready to wire in the fan.
It was actually kind of a pain in the tukkus to wire in the fan wires. The power lines to the RAMPS board are rather thick wires, while the fan wires were very thin. They didn't want to share the same screw terminal.
Smoke test: What many people do not know is that modern microelectronics run on smoke. If the smoke gets out, the electronics stop working.
No, really. They run on smoke. Have you ever seen something microelectronic billow smoke and still work afterward? Case closed.
Anyway, it was time for the smoke test. I plugged in the electronics board, and hoped it did not produce smoke. The fan started running, an LED on the RAMPS board flashed a little bit, and no smoke. Successful test!
Time to wire it up to the printer.
Well, okay, not really...
