Faraday For Fun: An Electronic Batteryless Dice

Step 10 Using the Batteryless Electronic Dice

Once the assembly is complete and the two tubes are secured together, the dice is ready for use. Just shake it a few times and a random number would appear. Shake it again and another random comes up. A video of the dice in action is here, also posted in this Instructables video:

The project is really cool, but u call it a batteryless dice. Real dice don't have batteries. Its a really cool idea, but what's the point when you can just use real dice?

It's cooler. And it's electronic and batteryless. Its not just batteryless.

-.- ... guess we'll call it batteryless electronic dice. as most of the things on this site the point is ... just doing it!

You could look at it this way: a traditional dice is batteryless. An electronic dice is not batteryless and this is a batteryless electronic-dice.

But no, a capacitor is a battery of sorts, so this is not batteryless

Respectfully, I know it has become popular to erroneously to refer to a battery, when they are completely two different items. Popular doesn't equal "battery of sorts", so this project use no battery. Yes it's "batteryless"
