Making a PCBMilling:
I milled my copper-coated board on the Modella mini milling machine. I used a 1/64" bit to cut out the traces, and a 1/16" bit to cut out the board itself. At first, I attempted to use the CAMIT tool, but it gave me a bad RML file. I am realizing more and more why some people prefer the directness and simplicity of the comand line over GUIs.
I have had quite a bit of practice soldering before, but never with surface mount components (SMDs). I did not do my first couple connections perfectly, but I eventually learned how to solder the SMDs quickly and securely. The really nice soldering irons with tiny tips that are actually hot helped enormously.
My board was successfully programmed on the first go and also was able to program an Arduino microcontroller.
