Electronic Shaking Dice Soldering Project

Build and shake this fun Velleman MK150 DIY electronic mini kit. No need for a push button, this kit uses a roller ball switch and a pre-programmed microcontroller. Just shake it to activate and the 7 red LEDs slowly light to roll through number combinations. The last number combination flashes. A battery holder for the 3V battery is included and attaches to the PCB. The circuit has an auto power-off feature to save battery life.


  • Power supply: 3V-battery (not included)
  • Dimensions: 1.4" x 1.4" x 1.3"
  • Microcontroller-controlled
  • Auto power-off

Frequently Asked Questions

Q. Since this MK150 kit is out of stock (and I need them for May), what other kit is similar to this? I wanted to use this kit with a STEM group of elementary students! Thanks, Tanya


We highly recommend the MK102 for elementary students.

Q. how much would it be to replace the circuit board alone? And how much would it be to buy a rolling ball switch (shaking sensor) alone and where can I buy it?


Unfortunately, MK150 parts are not sold individually. If your MK150 falls under our warranty, we may be able to send you replacement parts free of charge.
