Cheap (still unpolished) timer

Post by jpswensen » Thu Mar 15, 2018 9:27 am

I see there are plenty of people who have made DIY timers, so maybe this is redundant. Our pack recently got a nice new extruded aluminum track, but didn't want to spend the money on a timer that year. So, being a roboticist and tinkerer I decided to build them one. I am still working on polishing the documentation, making an official PCB design, publishing the 3D printed parts for various tracks, etc., but it has now worked for 4 races without a single problem.

We basically don't have a LED finish line, but project the GUI up onto the wall with a projector.

Currently everything we have is at
https://github.com/jpswensen/SunnysidePWDTimer

The (really bad) documentation is at
https://github.com/jpswensen/SunnysideP ... umentation

Future plans:
1) Handle more than 4 lanes
2) Use the WIFI capabilities of the microcontroller to not have to plug in over USB
3) Handle heats, dens, etc.

Edit: As opposed to our video, we have no plans of ever charging for this.

This is pretty cool! Where in the docs would I see the assembly schematic?
