       I've really been wanting to write a tutorial for making Cantern Jr. bicycle lights out of tin cans, but i felt like the construction required too many specific materials and tools. I want people with even basic tools to be able to build them. So, as i build this Cantern Jr. tail light for my e-bike, I'm experimenting with a simpler way of constructing them. Instead of using a piece of aluminum plate cut with a hack saw or band saw and bent in a vise for mounting the LED inside the can, I'm using a scrap of another tin can, cut with tin snips, and bent into shape by hand. I think it's going to work just fine.

       Building one will still require a 3D printer, wire cutters/strippers, and a soldering iron, but at least I've eliminated the need for a saw an a piece of aluminum plate. I could probably eliminate the need for the 3D printer as well, but the light would be getting very jankily built by that point

       The headlight version of the Cantern Jr has a focusing lens for the LED and a clear plastic window to protect everything from the elements. This is a tail light though, and it  just needs to be visible to others, so I'm dropping the focusing lens and replacing the clear window with a diffuser made from a diffuser sheet from an LCD TV. It's very bright!

       @MLE_online does the can get very hot? I did some experiments with an aliexpress LED module and totally toasted it due to insufficient heatsink
