Gauges conversions, photos, how I do it and system descriptions
Autopilot, which was halfway finished for a long time, has now been completed and tested. The problem was the pitch wheel assembly is a rather complex design with solenoids and resetting potentiometers I just could not figure out how to interface so I decided to strip everything and place 360° high-definition hall sensors on the […]
The 2 ADF radios on the control stand are now converted and ready for codeing. I had to replace all bulbs which takes some time as they are soldered to a flexible circuit board. Bulbs are 680 bulbs, by chance I had 80 new bulbs from a previous wrong order. VHF/NAV are next.
Meter Altimeter finished. Initially I tried a 1/10 geared stepper motor but that turned out to be too slow for any kind of quick descents. So I had to split the needles in two using one stepper motor per needle. Works perfectly. The QNH is set in the gauge itself not via a potentiometer. The […]
Finally the four DME indicators are completed & tested. So far I have completed 6 unites of which 2 are being used in the SABENA 707 sim in Brussels which I am helping to build up. I used 3 NEMA 8 stepper motors running at 1/16 steps. Position initialization done via light sensor. A rather […]
Finally started working on the 4x Bendix RMIs. These hat a specially made dial for Lufthansa. Now working on 12V stepper motors with 1/16 microstepping. More infos and video to follow
