Thrustmaster T3PA Load Cell Brake Mod

The project was inspired by RamjetX, both the sketch and housing for the boards were made by him. I did two versions as the first version I was not happy with the foam that I used as it was really stiff requiring a lot of pressure on the pedal to reach 100%.

Purchase List:
Load Cell Weight Sensor 20KG 
HX711 module
Pipe insulation or similar
Mini push-button   
M3 & M4 screws vary based on the load cell version

Wiring Diagram: 
I made this wiring diagram to make it easier for soldering the wires as well as make sure you switch the resistor from 10Hz to 80Hz. You can add soldier at 80Hz instead of resoldering again. 

You will probably need a knob where the foam will be glued on. Ramjtex used a drawer knob but I couldn't find anything laying around. So I used the same knob that was designed for Ender 3 Printer. Just make sure you print it at 100% infill or it will break easily.

Load Cell V1:

In this version, I made two mistakes as I used a very hard sponge which made it very hard to push all way to 100%. The second thing when I printed the knob, I forgot to set the infill at 100% instead I had it at 20%.

Load Cell V2:
In this version, I changed to pipe foam insulation as it gives a better feeling and less pressure needs to be added to the pedal.
