Well then I just have to cross my fingers that the 3d printed holes come out very nicely.

Has anyone tried using a sliding Potentiometer instead of a microswitch, to gradually slow down the vehicle and thus not cause any drifting? The Wingnut can push the protruding knob and reduce the voltage to the motor instead of switching off the power.

Clever idea, I have never tried it. The issue I see with that, is when you are gradually introducing your braking force, its not going to actually help you, it will hurt you at the very end of the run. Think about it: your car will be going faster right before the final mechanical stopper engages than if you immediately cut power, which kinda defeats the purpose.

The Potentiometer will gradually reduce the electrical Power, and should only slightly increase the braking force. Since this is a slide Potentiometer, the arm of the wingnut can be positioned to hit the Potentiometer when the vehicle speed needs to be reduced.

I've been trying to work out a formula for my car. I found the degrees of turning per cm, and multiplied it by the cm that I want then divide by 360, I used the degrees/cm based off of a .2mm off 12m run, but if I use that for a 9m run, it comes up 45cm short? Any ideas why

any tiny error in your calculation could have easily multiplied so you have to make sure your numbers are exact.

Also, calculate all the true values experimentally. Each part has some tolerance, and these build up, and make your theoretical calculations inaccurate.

I'd like to implement adjustable steering in my buggy for next year. So in the video below, Nestor revealed his secret of caliper steering.

Would I be able to use this kind of steering without the electronic caliper?

Its the same thing as the threaded rod steering thing, its just implemented thru the pillow block instead of the entire chassis as a whole

Dial calipers are not electronic.
