    Hi All,
    After using my custom handbrake for a while I'm thinking about making a few of these to sell. Would anyone be interested, and if so what does the community think I should be selling them for?


    The standard potentiometer USB handbrakes with loads of slop in the mechanism go for £70 ish.

    My "Pro" version has the following features:

    Upgraded oil impregnated sintered bronze bushings and shoulder bolts to take all of the slop out of the lever

    It uses 50kg load cell technology with 1024 bit precision.

    It comes with a user changeable selection of springs to vary the travel for a given force.

    The lever can be aligned vertically or horizontally.

    The brass parts are turned by me on my lathe, the loadcell assembly is a custom design of my own creation, as is the Arduino code.

    It appears as a single channel Arduino joystick ️ on PC, which channel it uses can be customised on request. I've been using Z rotation.

    Let me know what you think, if there's enough interest and it's economical for me to make a batch I'll look into buying the parts to make a few.

    Any constructive thoughts, or pre-orders lol ;-), would be much appreciated.

    All the best,
    Barry M
