Solar Cricket – finally, I get to build something…

Solar Cricket, from MAKE magazine

It’s been a busy year so far – lots of stuff going on, and precious little time to build anything.

A couple of months ago however I was asked by my buddies at MAKE magazine to put together an interesting little project. A solar powered chirping cricket – that uses solar energy to maintain the charge on a 9v battery, and then starts “chirping” once night falls.

As well as using the solar panels to keep the 9v Lithium Ion battery charged, they are also used for the light detection routine. The project also features the excellent JeeLib library to manage the low power sleep routines.
