aPionics uses the Raspberry Pi to drive external avionic instruments.

Cockpit instruments controlled by a Raspberry Pi.

Instrument Needles

Roof flashing makes a suitable material for making the instrument needles.

Instrument Housings

The housings are up-cycled food containers from the local deli. There are a few possible advantages to making stand alone gauges.

Possible Advantage

  • Can be used on a desk.
  • Later they could be installed into a panel.
  • Can be using the ones made while the next instrument is being developed.
  • If one instrument is lacking, it can be used while an upgrade instrument is being worked on.

Fuel Gauge

Inside of the fuel gauge, made for the DC-3

The inside of the fuel gauge is shown in the photo. The needle movement is accomplished with a hobby servo. The fuel tank selector switch takes advantage of one of the Analog to Digital Converter (ADC) that the TINKERplate has. The resistor, soldered to the rotatory switch is a simple voltage divider. Every used switch position is assigned a voltage level that corresponds to a specific fuel tank.
