Handbrake for Sim Racing

thingiverse

Handbrake A handbrake to use in driving games. The picture of the assembled design gives an idea how everything fits together. Putting it all together inside the small enclosure wasn't easy. All parts don't need to be printed. For example, M5 or M6 threaded bars can be used for different axles instead. In addition to the printed parts you'll need some M6 threaded bar, M6 nuts, some screws and something for the handbrake lever. I used a piece of 25mm pipe with holes drilled for the axles. That was from a leftover clothes rail. Original FreeCAD files of the design are included. I didn't use any Assembly module for FreeCAD, so almost all parts are created in the same file. PCB A simple PCB for PIC18F2550 and supporting components was designed using Fritzing and ordered from Fritzing Fab. The device connects to a computer via USB and presents itself as a USB keyboard or an analog game controller. The device is also powered by its USB connection. The design fits this PCB, barely. It's not easy to get the PCB in its place. Schematic and Fritzing file are included. Software If implemented using the given schematic, only software component required for this project is the PIC firmware written in C. The device can act as a standard USB keyboard or game controller recognized by Windows. So no extra drivers are required. I haven't finished my firmware yet. I have only made the minimum to read data from the device to see that everything works. Print Settings Printer Brand: Ultimaker Printer: Ultimaker 2 Rafts: No Supports: No Resolution: 0.2mm Infill: 20% Notes: Design has been made so it should require any extra supports to print.
