Running on Rays of Light and Off-the-Shelf Hardware
We have previously looked at how to make a wireless device live for years on one tiny coin cell battery. This time we up the game and make it live forever, using solar power and off-the-shelf hardware.
We build a prototype of our device and go through the technical details involved in designing for solar power. We use off-the-shelf hardware running the latest version of the Thingsquare ultra low-power software. Light does not provide a lot of power, so we need software that can make the most of it.
[...] There are many situations in which we would like a wireless network that lasts forever:
- Large-scale vineyard monitoring: keeping track of the vines that make up fine wines
- Checking up on those organic crops: believe it or not, agriculture is all about data
- Big city life: cities have parking spaces, trash cans, bus stops, trains and other urban necessities that need to be kept track of
- The great outdoors: knowing where cattle and livestock live their lives means farmers can save money
Sounds like a great project.

TOO BAD YOU CAN'T BUY a voodoo globe so that you could make the earth spin
real fast and freak everybody out.

In the grim darkness of the far future, a young string programming neural net will ask its fellow quantum programming nets while taking feedback on the kernel design, "Can we stop emulating the VT100 now?". To which, a senior would reply "0x4e6f2e0a" while a marketing AI will start a flame war saying "FTFY: 0x4e6f2e0d0a".
