DIY: Li-Poly battery charger project
A 'short' project; convert a lipo charger into an arduino controlled system with a nicer display and 16bit a/d converters for voltage and current monitoring. Lots of useful features and open source, when its done.
A lot of time being spent crafting a color display style that is useful for the application and still fits in the 30k arduino program size limit. It also has to poll for values, update the screen adn control some devices (digital pot, relay, buttons).
The display is a $5 (!) tft display that is 1.8" and uses ST7735 chipset protocol, which is somewhat common (SPI based); 160x128
