I decided I wanted a 14-pin ATtiny{2,4,8}4 adapter for my 8-pin ATtiny{2,4,8}5 Tiny AVR programmer. Was annoyed by the “zero-ohm resistors” I got in a resistor pack off eBay (less than half of which were the advertised values…) but found a use for a few of them. This board is mounted on a bit of header strip that I can remove to program the 85s and replace to program the 84s.

avrdude: initialization failed, rc=-1

Double check connections and try again, or use -F to override this check.

Oops. Followed an incorrect pinout diagram, it seems. Back to the soldering iron!

Working much better now!

I also had to turn it around because I had sketched out wiring it both ways before deciding, and then mistook which sketch I grabbed. It doesn’t really matter but it means that it doesn’t look quite like the picture in practice. ☺

https://github.com/petercriddell/little_simon/pull/1 would have been more of a pain to implement without this little daughterboard. ☺
