diy throttle quadrant

[flak1962]

guys does anyone have links for electronic parts for a diy throttle quadrant

 

analog  potentiometers ,usb interface board etc 

uk suppliers 

thanks,fancy trying this now after a successful switch board build

I found several suppliers of components including a 3-turn pot that I used for throttle. Fun and challenging at the same time.

For make a throttle quadrant you need:

 

 1 - An USB controller, the most popular of the self options is (as linked by Dagowoodyt):

Leo Bodnar BU0836A - control 8 axes, 32 buttons, 1 POV HAT (can use as more 4 buttons).

Derek Sphere Designs DSD 12 - control 5 axes, 32 buttons, 1 POV HAT (can use as more 4 buttons).

 

Or you can use low cost ($5) Arduino PRO Micro, STM32F130 clones flashing then with MMJoy2 and FreeJoy firmware respectively.

Both control 8 axes, up to 128 buttons, POV HAT (not use if 1 or more).

 

2 - A sensor for translate the Quadrant lever movement in electric signal, being the more easy to get an potentiometer.

 

However hardly you will find the correct potentiometer, the "joystick" potentiometer, that differ from ordinary potentiometer in the "effective electric angle", odinary potmter have 270, 300º of "effective electric angle", "joystick" potentiometer have 30 to 60 or 90º of "effective electric angle".

 

A Quadrant (Throttle, joystick, rudder pedal) have limited angle movement - perhaps 90º (a typical joystick is ~20+20º), so you want a potmter that match as best as possible this angle.

 

An example, 251B12T104A2NB used in T.16000M twist axis.

Instead potmtr can use a Hall Sensor, in DIY assembly or ready to use version.

Example (a 60º "effective electric angle model): https://br.mouser.com/ProductDetail/BI-Technologies-TT-Electronics/6127V1A60L5?qs=sGAEpiMZZMs0JOhy9PM0UT2KuCf1H3wX0A4NJp8zcxs%3D

 

Or more advanced sensors, like TLE5010, AS5600, KMZ-41 based (GVL224 MagRez, Rel4y sensor....)

 

3 - Extra buttons  - press or toggle, Rotary Switch, Encoder, HAT (4/5 way switches). 

 

4 - The physical parts of the throttle, a box, support for axis levers, etc... that, depend on your DIY skill and tools can make with metal (e.g. aluminum sheets), wood, plastic... or 3D printer parts - you don't need own a 3D Printer, can use 3rd part printer service near you, look at 3Dhubs.

 

Finally, being new in this area, best to do is "inspire" in someone job, maybe adapting for your needs, available materials.
