circuit ideas
I've been working on a board LiPoly battery charger / buck/boost board. It uses the
MAX1555 single-cell LiPoly charging IC and the
TPS63001 3.3V fixed output buck/boost converter IC. I've received (from
OSH Park) and tested a first version of the board, and have put in the order for a second version with a number of improvements.
status: parts ordered
I'd like to create a low-cost energy monitor using
this current sensor from SparkFun. The idea would be to have only real-time output, probably over Bluetooth so it could be read using a computer or a smart-phone.
The problem with that design is that, as the current sensor is simply a transformer, it can only be clamped around a single AC wire.
status: ugh
I'd like to make an AVR ISP programming bed using
pogo pins, so I can program boards without having to solder on ISP headers. It would either just be a passive adapter type board, or possibly have all the programming circuitry on-board. If I did make it a full standalone programmer, I would most likely just use Adafriut's
USBtinyISP design.

Working on an ATmega328 based board with an RN-42 Bluetooth radio. The board will have a variety of inputs and outputs, and a straight-forward serial command set to control them, e.g. "setHigh,1\n", "getTemperature\n", "attach,getState,sw1,setState,led1\n".
status: thinking - will start with software
Been playing with
amforth; perhaps a forth based pocket pc type thingy.
