This project box is an all weather self contained low maintenance long duration tool. For what, I’m not really sure yet.
Powered by the sun it stores energy in two NiMH 1.2V C size batteries that in turn drive a Maxim max756 DC-DC step-up converter giving 3.3V or 5V under 40X picaxe microprocessor control from which to operate.
A 433MHz transmitter sends data to the receiving project box that displays information on large character 2x16 backlight LCD. Both boxes use PICAXE-28/40 Proto Board (AXE022) and small breadboards.
