Why educators choose us

Designed for classrooms. Proven since 1996.

Every decision in the Mr Circuit system — from the breadboard to the lesson plan — was made by a teacher, for teachers. This isn't a hobby kit with a curriculum slapped on. It's a complete instructional system.

32 individual experiment kits — one per concept
The MC1-SET isn't one shared lab. It's 32 separate, individually-bagged experiment kits — one for every experiment in Lab 1. Every student builds something different at the same time. No waiting, no sharing, no kit rationing. And because every kit is reusable, the cost works out to a few dollars per student per year — a real number you can put in a curriculum budget request.
"My students are more engaged than they've been in years. They're actually building circuits — not just watching me build them."
— CTE Teacher, California
No soldering. Safe for every student.
Solderless breadboard design means zero open flames, zero burned fingers, and no liability concerns. Students as young as 4th grade can use the kits independently.
Full curriculum included — printed + digital
Every kit ships with a printed lab manual and access to the online platform: flipbook lessons, video walkthroughs, quizzes, and printable student certificates.
Reusable for years — not a one-semester kit
Components unplug and snap back. Students rebuild, swap circuits, and experiment freely without consuming parts. Most classrooms get 3–5 years of use from a single MC1-SET order.
A few dollars per student. Real budget numbers.
The MC1-SET is $164 for 32 reusable experiment kits. Across a class of 30 students over 3 years, that's around $1.80 per student per year.
Direct support from Gary — the person who built it
There's no support ticket queue. Email or call Gary directly. He's been answering teacher questions since 1996 and knows every circuit in the kit by heart.
