As I'm cheap I was originally going to just breadboard the "Arduino as ISP", then I remembered I had a scrap Arduino Nano with a blown 5V regulator. As the programmer will always be on USB by definition, this would do for a more permanent solution.
After building it based on the tutorials with one slight modification (there is a jumper on the RST cap so it can be disconnected for programming) I realized it would be a bit fragile for repeated use with all the little wires.
That's when I spotted that the little 3cmx7cm board I used fits almost perfectly in an empty pill bottle.

I used a 22uF cap for the reset not 10uF, as that's the closest I c
