DIY ATtiny45/85 ISP Header

ATtiny ISP header in practice

A quick weekend tip for a change, I thought to share a nice small soldering project will make programming ATtiny45 and ATtiny85-based projects a flash:

Basically I took a piece of veroboard, soldered some extra long pin headers on the bottom so it will form a tent of sorts above a ATtiny45/85 attached to a breadboard project. Then I soldered a 6-pin header to attach the ISP programming cable to, and used short pieces of jumper wire to route the header pins to correct ATtiny85 pins.

Now whenever I need to flash a ATtiny45/85 project sitting on a breadboard, I can just put this on top of that and never need to look up the pin layout again!
