Yeah, still trying to find time to build an actual cockpit. | |||

|- | |||
|Getting an arduino to blink Morse Code | |||
|Just for the exercise. | |||
|Done | |||
|- | |||
|Getting an arduno to drive several meter movements through a 16 channel I2c PWM controller | |||
|eight meters in all: Fuel, Left & Right, Oil Pressure & Temperature, & 2 cdi indicators each with horizontal and vertical needles. | |||
| | |||

|Getting an arduino to drive a 28 BYJ 48 stepper motor | |||
|For the Altimiter | |||
| | |||
|- | |||
|Getting an arduino to drive a dual needle Stepper Motor | |||
|For the Chronometer? What about second hand? Take apart and re-design? | |||

|Getting an arduno to drivean x27-168 | |||
|Tachometer & Airspeed | |||
| | |||
|- | |||
|Build the Tachometer and Airspeed Indicators to Flightgear standard for C172P 1982 | |||
| | |||

|- | |||
|Build the altimeter | |||
| | |||

|Design and Machine Aluminum Bezels for Tachometer, Airspeed, etc. | |||
|Need: | |||
* Design in OpenSCAD | |||
* Machine on Tormach, Aluminum or Black Plastic or Composite Material. | |||
* Paint if Aluminum | |||
* Fixturing for Plastic needed. Central hole is large in comparison to remaining material. Material can deform in the revise. Needs to be attached at multiple point to something stable if machining as one piece. Just putting the blank in a vise won't work. | |||
| | |||
|- | |||
|Design Fixture for machining Prism and Flat lenses for Instrument Illumination. Figure out how to trim the square prisms as the desired shape. | |||
|Need | |||
* to hold a piece of plexiglass to be resurfaced at the correct angle as a prism | |||
* to hold the prisms in place so the outside edge can be machined. round for the flat lens and one of the prisms, complex shape for the prism. | |||
* Will laser cutter do for the outside machining? | |||
* Paint part of the edge of the prisms | |||
| | |||
|- | |||
|Machine and Polish Prism and Flat Lenses | |||
|Do the work on the tormach. | |||
| | |||
|- | |||
|Connect Altimiter, Tachometer, Airspeed, Fuel and Oil Gauges to Flightgear | |||
|Plan: | |||
* Use the Left Panel Shock Mount from the Cessna 172N I got for $50 on ebay. | |||
* Use the standard subscription mechanism, or poll the properties directly. | |||
* First cut, no calibration, let the indicators work of raw data. May need functions to do relative scaling of normed properties | |||
* Second cut, add calibration tables for the properties. | |||
* Third cut, provide a UI for calibration tables | |||
* Fourth pass, persistence for calibration tables and property paths. | |||
