An Electronic, Battery-less Dice

A Microcontroller, AVR Tiny13 based electronic dice, that does not use any battery or any normal power source. Instead it derives its power from a voltage generator based on the Faraday principle using a coil wound over a tube and a magnet inside the tube. To use the dice, just shake the circuit a few times and it produces a random number between 1 and 6 and displays it on the LEDs. Background music: Por Una Cabeza by Carlos Gardel.

Sure. But a real die isn't electronic either.

You should take that thing to an airport.

[dhananjaygadre]

@lerikhkl Yes! They get freaked out. But I can't take it in my carry on baggage any more. Haven't had any problem with my checked in luggage till now though.

post the schematic for all your projects they are good

how fast is your crystal oscillating?

[dhananjaygadre]

Its using an internal RC oscillator of 128 KHz

It's an Argentinian tango call "Por una Cabeza" (for one head).

By the way, when you say "terrorist", Do you really believe that you're funny?

[FlyByPC]

Cool idea!

[mondalaci]

Masterfully done, kudos for ya!

[neeb001]

A real die requires no batteries...
