ATtiny13 MCU powers DIY digital dice kit

A new Atmel-powered DIY digital dice kit recently surfaced on eBay. Designed and sold by eBay member “applemount,” the DIY digital dice kit features Atmel’s ATtiny13¬†MCU, front and center.

Aside from the ATtiny13, additional key components include:

  • 1 – Lead-free professionally printed circuit board (2″x2″)
  • 7 – Red LED’s
  • 1 – Battery holder
  • 1 – Button switch
  • 1 – CR2032 battery (included)

“Push a button and the die will display a random number from 1 to 6 just like a dice! [The kits are] great for board games. [Plus], you get a free CR2032 battery with each kit!” applemount wrote in a description posted on eBay.

“[The kit] uses advanced on-board entropy collection to generate real random numbers. Soldering is required, [although] each part is clearly labeled on the printed circuit board for easy assembly.”
