We’re always on the lookout for fun and relatively easy electronics kits to recommend to those learning how to solder. This LED Shaking Dice kit (US$14.99) being sold at Think Geek looks like it fits the bill. And it meets one of our other criteria: it’s cheap! When you’re done with the build, you have a cool-looking random number generator that’s triggered when you shake it. It flashes away through its random number sequence, finally displaying a number of lit LEDs like the dots on an analog die.
