in 2022 i put an arduino in an altoids tin with a gas station usb power bank and had it run bitlash on an oled. i used the space really inefficiently by breaking out the pins in the weirdest way possible, there was interference on the connection to the oled module that made it fail to initialize half the time, and the battery would automatically shut off after like 60 seconds if there wasn't a phone plugged in. i added a little usb keyboard emulation cause it was an atmega32u4 but it kept crashing or something. also i designed and ordered a custom pcb for the keyboard but then i went and bought an m5stack one cause once i saw the bag of all the tactile switches and put a few of them on, i realized i didnt wanna do all that surface mount soldering myself lmao this was what i had before i knew what a flipper zero was i wanna do a version 2 of this though cause like its so cute its just a little guy. i love altoids tin computers theyre literally snack sized
