Parts List

Just in case you're in the UK. :)

Schematics

PCB Gerber Files

This is the main PCB files in Gerber format ready to be built. This is Version 3.04 which resolved a design issue in Version 3.03 which required three bridging wires to link the 2.5 mm jack to the Transistor - doh!

Code

Arduino IDE Code - Intervalometer V3.2

Inside you'll find all the files you need. Once you've built the board, flash the RTC using the script enclosed, and then upload the actual Intervalometer code. :)

Gamble everything for love, if you are a true human being. Halfheartedness does not reach into majesty.
Thanks to Tjurik.
