Who is this kit for?

Based on our experience, an 11-year-old kid should be able to assemble a Ringo kit with a tiny bit of help from an adult. Estimated build time: 5 hours.

Building the Ringo kit is just the beginning.

After that, you’ll spend numerous hours creating your own games and apps and experimenting with hardware.


What you’ll learn with Ringo

  • how to solder properly
  • what are the basic electronic components and what are their functions
  • what are microcontrollers and some basics of digital electronics
  • how to program a microcontroller in C++, Python and other
  • how a basic mobile phone works


Ringo needs tools

You’ll need some basic tools and equipment for assembling your Ringo

  • regular soldering iron (nothing super expensive is required) and some solder
  • diagonal cutter pliers
  • regular screwdriver
  • some solder
  • a piece of insulating tape or some super-glue

Or you can buy a kit with a tool pack already included.
