Welcome to Tenka Labs

Tenka Labs is an exciting new company that develops innovative STEM toys for Makers ages 8 and up (see our recent media coverage). Our first product, Circuit Cubes, are electronic building blocks that bring kids' creations to life. They were built from the ground up to fully integrate with all major brands of building blocks, but can also be used with any materials kids can imagine — from vintage toys to recycled milk cartons. Circuit Cubes teach the basic fundamentals of electronics. Their unique, semi-transparent design enables kids to literally see the connections they make when they light an LED, power a motor, or activate a switch. Circuit Cubes can also be used vertically, horizontally, and diagonally to accommodate any design. Circuit Cubes were designed by STEM educators and FIRST LEGO League coaches, Nate and John.



Our Story

Co-founders Nate MacDonald (right) and John Schuster met while working at a Marin County, CA, school district. Nate was teaching math and offering an elective STEM course to middle school students, and John was hosting “lunch and learn” events to teach kids circuitry. (His “real” job was in the district’s IT department.) Determined to better engage their students, they teamed up to find the best ed-tech toys for understanding circuits and how they work. After reviewing a number of electronic kits — and even hacking some to create the quintessential teaching tools they envisioned — Nate and John decided the only course was to make their own. A crude early design was launched at Maker Faire Bay Area 2014 and their first company, IgnitED Learning, was born. (The name was later changed to Tenka Labs, “Tenka” meaning “ignited” in Japanese.) John soon quit his job in order to concentrate full-time on prototyping the set of electronic tiles that eventually became Circuit Cubes. A year later, Nate ended his teaching career to devote himself full-time to designing a toy line that is as much fun to use as it is educational.
