As technology advances, we get to see some interesting camera-related inventions. Engineers at the University of Michigan have recently presented a prototype of a wireless camera that can power itself indefinitely by light. It’s also less than a millimeter wide, so it can be hidden anywhere.
There are few things that get me more excited than radio technology (…at least for the time being; I will probably find another obsession in a month or two). Add to that off-grid power and photography, and you’ve got my attention.
This creative setup uses a Raspberry Pi, some extra wires, a BaoFeng UHF/VHF handheld radio (have a couple of them myself and love ’em), and some scripting to capture images, convert them to radio waves, and transmit them via slow-scan television (SSTV) to a remote location…all run off solar power.
