This is a project that allows you to play around with switches and LED's. It's a reaction game ... for now, I am planning to make a settings/page button that allows you to play different game modes and stuff. But now it's geared toward an F1 style gameplay where the LED's close in on the center light and then they all go blank and it measures the time for you to let go of the "clutch" and hit the "accelerator". Maybe different racing types later?? I made this project as an intro into PCB's, circuits and soldering because it's my first physical project that I have done. I wanted to get into the hardware project and there was a nice guide, but no soldering guide so I get to do that on my own. So this is a bit later, and I added a battery compartment to it, it's now a mobile device and it doesn't have to be plugged in. I also am now planning to add a GT practice shifter to the code where you can practice shifting GT style. I also had to add 2 connectors so that I can solder the battery wires correctly.

Questions

How big is the EFidget PCB?

It measures 99.6 × 72.3 mm and has 2 copper layers, 1.6 mm thick.

What parts does the EFidget use?

22 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the EFidget KiCad files?

From the Awesome-XV/e-figet-pathfinder repository on GitHub, at the commit this page was made from: the board is eFidget.kicad_pcb and its schematic eFidget.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the EFidget design in my own project?

Its repository states no licence, so its author keeps all rights: ask Awesome-XV before reusing the design.
