So how am I going to trigger the brake light now that I cut the mount for the switch off?
Hopefully with one of the extra neat things I have in mind for this build.
I adjusted the bracket I cut off for the brake light switch to fit on the other side of the frame:
It's new job will be to hold the new proximity sensor for the brake lights:
The cool thing about this is that there won't be any moving parts or even contact of any kind... notice the clearance:
Part of the reason why I went this route is to clean up the outside of the frame... it's almost totally hidden from the side.
I will have to build a controller for this, but I was planning on doing that anyway. It has a pretty tight tolerance, so the brake light will engage relatively quickly once the pedal is pressed. Since this switch is normally closed, and opens when the pedal moves away, my plan is to use a pull-up pin that is activated in the up position - so when the switch is closed, the pin is low/grounded, and the brake lights come on. The benefit to this is that it will have a fail safe in that if the switch fails or the pedal doesn't line up for some reason, it will fail in the brake lights on position. I figure looking like I'm braking is better than actually braking with no brake lights.
Here's a video of the sensor in action - you can see the indicator light on the sensor turn on/off with the pedal movement.
