Flight Simulator - Throttle Quadrant/Pedestal - 737 inspired

thingiverse

This is a throttle quadrant inspired by the Boeing 737. Some basic electronics and programming knowledge are required to setup the Arduino code. Here's a video of the quadrant working in P3D with the PMDG 737: https://www.youtube.com/watch?v=VfrzoQfWrCE **FUNCTIONALITIES** * Speedbrakes (up, down, flight detent, axis) * Two-axis throttle control (with detent for reverse thrust) * Flaps (0 to 40) * Gear (up, down, off) **REQUIREMENTS** * 3x 100mm M3 or M3.5 threaded rods * 6x nuts (same diameter as the rods) * 2x M5 bolts for clamping * Rubber bands * 5x potentiometer * 1x Arduino with native USB capabilities, such as the Pro Micro (recommended), Leonardo **WHAT TO PRINT** * 3x separator.stl * 2x throttle_separator.stl * 1x flaps_separator.stl, gear_separator.stl, speedbrake_separator.stl * 4x lever_base.stl * 2x throttle_lever.stl * 2x throttle_lever2.stl * 1x flaps_lever.stl, gear_lever.stl, speedbrake_lever.stl * 2x label.stl * 1x label_small.stl * 6x spacer_big.stl * 15x spacer_small.stl * 2x clamp.stl **ASSEMBLY** General guidelines: 1) You must **first** assemble the potentiometer + levers + separator for each lever 2) The spacers go in the threaded rods. See the image on where to put them 3) The rubber bands connects the lever base to the custom lever for each control and provide the "spring" loaded action 4) The potentiometers must be fixed with the potentiometer nut into each specific separator 5) label.stl and label_small.stl must be super-glued to the specific separator 6) Print and cut the labels.png file and glue them to the label 3d printed part. The order of assembly goes as follow: Clamp Separator Speedbrakes levers + small spacers Speedbrakes separator Label glued to speedbrakes separator + big spacers Throttle separator Throttle levers + small spacers Separator Throttle levers + small spacers Throttle separator Label glued to flaps separator + big spacers Flaps separator Flaps levers + small spacers Separator Gear levers + small spacers Gear separator Label small glued to gear separator Clamp Finally, add the nuts to each threaded rod in order to clamp everything together. Also add the two M5 bolts to the clamp part and use it to fix the whole assembly to the table. **SOFTWARE** Click the link below to download the .ino file: https://www.fergonez.net/files/throttle.ino Wiring a potentiometer to an Arduino is very basic, so I'm not going into detail here. See the Arduino tutorials for that. Each potentiometer must go into an analog port of your Arduino The code below uses the joystick USB library, so it will appear as a regular USB game controller in Windows. Throttle and speed brakes are mapped as axis and the gears and flaps are mapped to button presses (one button to each detent). You will probably have to change the Arduino code in order to properly map everything based on your own potentiometer readings. They are all under the *CALIBRATION* section of the code. You may also have to change the analog inputs your are using for your potentiometers. Hope you enjoy this project! KR, Fergo
