Sometimes I miss the smell of soldering. I get to solder a little but not much when connecting the few wires that are used. The CPU is a standard part you get when buing Texas very inexpensive $30 development kit. For the sensors only 6 wires are used vcc,gnd,data in to the Zigbee, a snooze wire and two wires for differential ADC input. The ADC wires are connected to 10 mOhms measuring resistors. The software takes care of both ways of connections to the resistor. For the receiver part I expect to have connections for data and sleep from the Zigbee, a single button input and a wire activating a relay for power to the display.
