tomu is a fingernail-sized computer that is easy to swallow

i’m a huge fan of single board computers, especially if they’re small enough to swallow. that’s why i like the tomu. this teeny-tiny arm processor essentially interfaces with your computer via the usb port and contains two leds and two buttons. once it’s plugged in the little computer can simulate a hard drive or mouse, send midi data, and even blink quickly.the tomu runs the silicon labs happy gecko efm32hg309 and can also act as a universal 2nd factor security token. it is completely open source and all the code is on their github.
i bought one for $30 and messed with it for a few hours. the programs are very simple and you can load in various tools including a clever little mouse mover maybe to simulate mouse usage for an app and a little app that blinks the lights quickly. otherwise you can use it to turn your usb hub into an on-off switch for your computer. it’s definitely not a fully fledged computer there are limited i/o options, obviously but it’s a cute little tool for those who want to do a little open source computing.one problem? it’s really, really small. i’d do more work on mine but i already lost it while i was clearing off a desk so i could see it better. so it goes.
