We’re happy to see Arduino enthusiasts championing the use of smaller hardware when the need for a full-blown ATmega-based board just isn’t there. [Chris] has been doing just that, using ATtiny85 chips in his projects. But he’s tired of hooking jumper wires to flash the sketches. He finally got around to etching this ATtiny85 programming adapter.
If the project is not pin hungry, an ATtiny85 can run Arduino sketches without the need to port the code. The best news is that the Arduino board you used to prototype the project can be used as the programmer for the standalone chip. Here that’s a Boarduino, and [Chris] laid out a double row of female pin headers for quick plug-in. To the right you can see the DIP socket for the target chip. Although this works perfectly well, we would have liked to also see the inclusion of a 2×3 AVR ISP programming header which could be used with the full range of AT chips.
