If you like tabletop gaming, there’s a good chance you use dice of some sort. It can certainly be fun to roll cubes around on the table and see what comes up, but why not take things into the electronics age with this “Shake me like a Polaroid Dice Kit?”
It uses an ATtiny85 microcontroller with a vibration sensor, and is programmed to generate a pesudo-random number from 1 to 6. On the other hand, if you’re somewhat paranoid, perhaps you would only want to use your own electronic die. who’s to say that your competitor didn’t reprogram it to show a certain number if you shake it in a secret sequence?
Though custom electronic dice might not be accepted in Las Vegas casinos, the Rcs27 store has a few more tricks up its sleeve, including this clever LED name badge. Not only can you write on it with an erasable or permanent marker, you can also print your own translucent label to identify yourself. It seems like a great way to stand out at a trade show, or perhaps also if you get together with people who are very bad with names!
