Circuits without soldering!

What began as a group of weekend builders and teachers coming together to create easy-to-use projects has now grown into a company with a passion for creating fun and practical educational products and kits.  Founded in 2012, Brown Dog Gadgets now offers educational products and do-it-yourself kits as well as consumer retail products. Equipping everyone from young 3rd-grade learners to experienced mountain climbers; Brown Dog Gadgets offers a wide variety of products tailored around alternative energy. We supply our customers with the freedom to explore life with their favorite gadgets by their side, thus reducing the world’s dependence on traditional power sources.

This organization is another by educators for educators which is AMAZING!  They are by STEM Educators for STEM Educators.  STEM is their focus.  However, we feel they should say STEAM because many of their sets incorporate the arts.  Their kits and projects are designed to unlock creativity in all students.

Crazy Circuits Bit Board Classroom Sets can be sold with or without the micro bits.

These Crazy Circuits Bit Board Classroom Sets expand the power and functionality of Micro:Bit significantly.   This kit covers topics such as circuitry, programming, logic, design, sewable technology, art, and design.

Creating a project from scratch can be difficult for the casual builder. Finding the right directions, the right parts, and the right tools—all at the right price—can be a major hurdle.  This kit solves all these worries.

The Bit Board micro:bit™ adapter classroom line was designed as a complete classroom solution for teaching programming with micro:bit’s graphic interface alongside the Crazy Circuits™ component platform. Teachers, you will save time by having supplies and a curriculum that takes little to no prep.  No need to worry that you will run out of ideas because Brown Dog’s curriculum is always being updated and aligned to NGSS standards for easy integration into any new or existing curriculum.

Take the guesswork out of Micro:Bit lesson planning and creation. Brown Dog curriculum and lesson plans focus on teaching students the basics of Micro:Bit programming while also having them create more complicated code in order to learn HOW different parts interact. They take parts such as distance sensors and show how to manipulate servos, 7 segment displays, speakers, and LEDs to show readings. Our goal is to inspire and engage students, not just teach them how to write lines of code.

*Computer(s) are required but not included.
