It's very nearly a thing

A project log for Darktimer

A countdown timer for use when you can't have any light. Multiple sequential timers stored in EEPROM, with coded beeps to indicate events.

After a few months of competing priorities, I have finally cut the case and installed some of the bits and pieces. The correct buttons just arrived this morning, so I can take out the placeholder buttons and actually wire up the fully-functional Darktimer v1.

Minimal testing suggests the code works fine with the power-saving features turned on -- primarily turning off pieces of the processor which aren't being used. I haven't measured current consumption yet, but now that I"ve got the code blown onto the Arduino Pro Mini, I expect it to be much lower.

The project page is more or less done, and can be previewed here:

Once I have the prototype fully built up, I'll be taking pictures and finalizing the project page. Looks like v1 is code-complete, and the first prototype is only an hour or two from being finished.
