What is this?
In a nutshell, STEM Box is like a Netflix for electronics-makers and electronics-makers-to-be.
You'll get a unique DIY project every three months, with all the necessary components, booklets, and online tutorials.
Throughout your subscription, you'll learn about many technologies of the future, such as microcomputing, artificial intelligence, Internet of Things, cybersecurity, and more.
Is this meant for beginners or experienced makers?
Both!
All our kits are completely tailored to beginners and no previous knowledge is needed to assemble them. We have prepared fun step-by-step instructions which will guide you through the entire assembly process.
And if you’re already an experienced maker, you'll enjoy tinkering with our fully customizable open-source hardware & software.
Projects in STEM Box subscription are also suitable for all ages and you can use them as a fun parent-child learning activity.
Which subscription plan should I choose?
The difference between our 3 subscription plans is in the number of projects included.
When choosing a plan, bear in mind that the more projects you go through, the broader set of STEM skills & knowledge you'll obtain.
Plans also differ in the amount you'll pay for one box. If you subscribe to the one-box subscription, you’ll pay $99.99 per box. But, if you decide to get a plan with a higher amount of boxes, you’ll pay less per box.
What if I just want to to try out one box instead of commiting to a subscription?
We offer a one-box subscription plan, so you can try out STEM Box and simply log into your account to cancel if you wish to not renew. You can cancel your subscription at any time and at no cost.
So when do I get my first STEM Box?
Once you purchase your subscription plan, you'll get the first box delivered to your doorstep within 10 days.
After that, the new STEM Box projects will be shipped to you on a quarterly basis (every 3 months). We don't charge you any shipping costs, no matter where you are in the world.

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

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.

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