laser tag-like game for bikes
what is this?
this is a laser tag-like game for your bicycle that lets you compete for points with a friend. basically, you strap some electronics onto your bikes and try to shoot each other with the sides of your bikes.
how do i build this?
you're gonna need the pcbs and the 3d-printed parts for the case. you can solder the components onto the pcbs as specified in the schematics/pcb files (note the values of the resistors!!) and putting the pcbs inside the cases. then you can close up the cases with 6mm bolts and feed your velcro strips through the back handles and you should be good to go!
note: please solder on the esp32c3's using the pin headers, otherwise there won't be enough space to solder in the resistors

| transciever |  |  |
what does it do/have?
- ir transceivers to do the laser tagging
- buttons and buzzers to send the signals to shoot and know when you're getting shot
- a central score counter
- communication with ESP-NOW
- a case for attaching the components to a bike with velcro
why does this exist?
i first had that idea a couple years ago and tried to implement it but kinda failed because i didn't supply enough power to the ir leds. but this one should fix it, especially in sunlight, since it now uses a transistor to power the leds. so this is basically me trying to redeem myself again :D

Questions
How big is the Warbikes transciever PCB?
It measures 34 × 69 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Warbikes transciever use?
10 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 Warbikes transciever KiCad files?
From the Milk-Cool/warbikes repository on GitHub, at the commit this page was made from: the board is kicad/transciever/warbikes-transciever.kicad_pcb and its schematic kicad/btn/warbikes-btn.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Warbikes transciever design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
