Reading and Powering a Digital Dial Gauge

Harbor Freight offers a decent deal on a digital gauge that also communicates its reading (much like a Chinese calipers).

I built up an MSP430 based solution to retransmit this data via UART and externally power the dial gauge (eliminating the need for a button cell battery).
