Our kits are made for learning new STEM skills. We're providing you with materials, instructions, and ideas, but it's up to you to build it and code it yourself. We strongly believe that once you make something with your hands, you're not only accomplishing something new, but also learning sought-after skills.

We have two product lines. One is for kids, and it includes STEM toys for ages 7+. The other product is for teens & adults. It consists of products for ages 11+, 14+, as well as more advanced kits for adults.

You will learn all the essential STEM skills that could define your future. You'll learn everything from electronics and robotics to coding and problem-solving.

We offer a variety of kits. You can build robots small and big, gaming consoles, AI-powered cars, smartwatches, and much more. For full product list, visit our official store.

We ship worldwide, so you can get a kit no matter where you are.

 

You get free tracked shipping on orders over $96 (€96 in the EU, to a pickup point). On orders below $96 (€96), shipping is $15, or €7 to an EU pickup point and €10 to an EU home address.

 

Saudi Arabia, the UAE, Qatar and Kuwait are the exception: orders there ship by express only, at $40, or $20 on orders over $96.

 

We ship from seven regional warehouses: in the EU, the US, Canada, Saudi Arabia, the UK, China and Australia. Your order goes out from whichever one is nearest to you. If you have any questions about import charges, please check this article.

No. But now you can buy whichever CircuitMess STEM kit you want and you'll even find bundles to get more kits at once while saving money. If you still have an active CircuitMess subscription, you will get all the STEM boxes you have subscribed to. After that, you'll be able to buy each product separately or in a bundle.

If you have one of our subscriptions you can manage it here.

You can access anatomy, build, coding, and usage guides on our learning platform, CircuitMess Resources, under the Guides section. All our projects are open-source, and additional product details are available on our GitHub repository. If you still can't find the answer you're looking for, you can always reach out to us at contact@circuitmess.com, and we'll be happy to help!
