It uses an atmel and is meant for a Canon, but the design is ingenious.

Or this: http://cms.diodenring.de/en/electron...tervalltimerv2 ; based on 10F222, works with Canon, Nikon & the newer Pentaxs.

Planning to build one for my Canon 500D...

I started with a Canon A570is and CHDK but wanted to use the DSLR for its many advantages, built the diodenring timelapse but my brand new pentax K-x does not have the 2.5mm jack as my previous pentax K-100, stupid me I realized this AFTER building it so the only choice left was to build it using the IR sensor. Crossed many mails with Achim (from diodenring) he is a helpfull guy.

Regarding the HDR-jack I think this can also be implemented via IR, but not looked into it yet.

Regarding the program in this thread, I know the timing loop at the begining can be improved using a better way to count time. I could use some help there
