Automotive Projects

Several projects are underway, but are pretty low priority time-wise.

  • Remote sensor. Measures two 12V sensor inputs (digital on/off) and ambient temperature. Communicates with remote inquiry source using RS-485. (RS-485 is a single pair, differential, bidirectional serial communications hardware standard.)
  • Display. Gathers data from remote sensor(s) using RS-485 hardware and software polling protocol. First usage would be for measuring speed and fuel injector modulation to calculate and display miles per gallon consumption rate. Intended to fit a 1" x 2" available panel space on one of my existing vehicles, which due to a manufacturer software bug does not deliver the data needed for commercial MPG indicators (1998 Ford Ranger).
  • LED flasher for fake alarm indicator. Flashes an LED when ignition power is off. Low power consumption.
