Start with their age and their interests. For younger builders, Beep Boop needs no building at all, and Codee 2.0 and Bit 2.0 are short, friendly first builds. Older kids, teens and adults tend to enjoy the bigger builds — Bit, ByteBoi, Wheelson or one of the music kits. Think about what they’re passionate about — gaming, robots, music, space? Each product page lists its own recommended age, which is the best guide. If you’re unsure, a CircuitMess gift card lets them pick for themselves.

All our kits are designed for beginners, so no prior experience is needed. Codee 2.0 and Bit 2.0 are the gentlest starting points, and both are assembled with the screwdriver supplied rather than a soldering iron. Every kit comes with clear, step-by-step instructions. Note that the Wacky Robot Bit Expansions are not building kits — each pack is a ready-to-use game token and trading cards for a Bit console, which is sold separately. See Wacky Robot Bit Expansions — Frequently Asked Questions.

Beep Boop suits the youngest — it arrives assembled with nothing to build. After that, Bit 2.0 and Codee 2.0 are the quickest builds and need no soldering. Larger kits like the Bit console carry a higher recommended age, but younger children often manage them happily with a grown-up helping. Check the recommended age on the product page for whichever kit you’re considering.

Teenagers are in a good spot for most of our range. Bit, ByteBoi, Clockstar, Jay-D, Synthia, Chatter, the Mars Rover and Wheelson are all more involved builds, and most of them introduce coding as well. Pick by interest — gaming (Bit or ByteBoi), music (Jay-D or Synthia), robotics (Wheelson or the Mars Rover), wearable tech (Clockstar, which they build themselves), or communication (Chatter). The NASA Artemis Watch 2.0 is the wearable option for someone who would rather code than assemble: it arrives fully assembled and ready to program.

Plenty of adults build our kits. Any of them work, but the more complex ones tend to be the most satisfying: Wheelson, the Mars Rover, Synthia, Jay-D, Clockstar or ByteBoi. If the point is the finished object rather than the building, the NASA Artemis Watch 2.0 comes assembled and can be coded straight away.

A bundle is a good hedge — it packs several different projects together, so there is usually something that lands. Otherwise a CircuitMess gift card leaves the choice to them.

Bundles pack several projects together and usually cost less than buying the same kits separately — good if you want to cover a few different STEM topics or keep someone busy for a while. An individual kit is the better choice when you already know the recipient is into one specific thing. What’s in each bundle is listed on its own page, so check there before you buy.

No prior experience is needed. All CircuitMess kits are designed with beginners in mind, and we provide step-by-step instructions for the assembly and, where it applies, the coding.

Yes. They’re written step by step with plenty of illustrations, and there are online build guides, coding guides and tutorials on Resources if extra help is needed. You can also message us here, or email [email protected], and we’ll talk anyone through a stuck step.

Orders are dispatched within 48 to 72 business hours. Transit after that is usually one to two weeks, but it varies by destination and can be longer if the parcel goes through customs, so we can’t guarantee a delivery date.

Because of that, if the gift is for a particular day, order well in advance rather than close to it. We ship from seven regional warehouses — in the EU, the US, Canada, Saudi Arabia, the UK, China and Australia — and your order goes out from whichever one is nearest to you. If you have a deadline, message us here before ordering and we’ll tell you what is realistic.
