What others say about us

The best way to encourage creativity for kids and adults! Level of difficulty goes up with each box, but it's all well written down and easy to follow so 10/10

Daniel Robert, Netherlands

We have recently started subscribing to circuitmess stem boxes to replace another known brand. The difference is night and day. Circuitmess provides fun projects for kids to enjoy. We have completed two projects and are looking forward to the next one. Albert and the team are always on hand to support and provide help if you need it. Well done team.

Daniel, Great Britain

Excellent kit for introducing children to electronics. It lets them understand that technology can be crafted and not only consumed.

Imagine being able to build your own fully functional mobile phone, all while learning the basics of programming and electronics.
