Crazy Circuits

LEGO compatible modular electronics

Crazy Circuits is a non-soldering electronic learning platform that allows people to create circuits from almost any material they can imagine. Crazy Circuits are designed to pop onto LEGO bricks, enabling your creations to light up, move, and make noise. Use Crazy Circuits to construct paper crafts with conductive tape, use conductive thread for sewing, sculpt with conductive dough, and create art with conductive inks and paints. You can even upload Arduino sketches to the Crazy Circuits Touch Board. No matter what you make, Crazy Circuits brings it all together.

Crazy Circuits works on LEGO , paper, fabric, and tons of other materials.

What does it do?

We designed Crazy Circuits to interface with all kinds of systems and materials that are already in your home, classroom, or makerspace. Start with simple circuits comprised of a battery and LED, then add switches, buttons, and programming boards to integrate sound, motion, and interactive elements. The real fun comes when you combine Crazy Circuits with your own creativity. Make a light up t-shirt, a singing greeting card, or a treat dispensing robot the only limit is your own imagination.

At the heart of our most exciting projects is the Crazy Circuits Touch Board. The Touch Board is built around a Teensy LC microcontroller and features capacitive touch inputs. Any conductive material, from a cup of water to a potato can be turned into a touch sensor, no grounding necessary. We’ve made light up T-shirts, a conductive paint piano, a music visualizer, and we’ve got lots more ideas on the way. We can’t wait to see what you create!

Who is it for?

Crazy Circuits is a great tool for anyone trying to get into circuit design and basic programming. From a kid making paper crafts, to an engineer building LEGO robots, Crazy Circuits has something for everyone. If you promise not to swallow anything, Crazy Circuits is for you!

Features and Functions

Endless Compatibility

There’s no need to reinvent the wheel. That’s why Crazy Circuits is designed to be compatible with all kinds of systems and materials that you already have on the shelf. If you’ve got a LEGO collection, you’re already most of the way to an ambulance with flashing lights or a rocket with glowing engines.

Our programming boards are Arduino based so even novices have an easy time getting started. All you need is a computer Mac, PC, or Linux with a USB port. You can copy our code, edit it, write your own, or borrow from the hundreds of Arduino projects already shared online. The Crazy Circuits Touch Board can also be used as a USB keyboard. This functionality is great for creating game controllers or buttons that launch apps or execute keyboard shortcuts such as “copy” and “paste” commands.

Crazy Circuits is compatible with any conductive material you care to connect to. Some of our favorites include our nylon conductive tape, Squishy Circuits dough, Bare Conductive Electric Paint, and conductive thread, but you can use anything you like. Paper clips, aluminum foil, and even pipe cleaners make great wires and touch pads for Crazy Circuits.

Color Coordination

Despite Josh’s inability to differentiate red and green, each type of Crazy Circuits Chip is a different color depending on what it does.

Open Source

Crazy Circuits is available for free as open source hardware and software. Our GitHub repository contains information for dozens of parts, complete with gerbr files and DigiKey part numbers. If you want to make or order your own Crazy Circuits, you can, even the parts we aren’t manufacturing yet.

We want to support the same maker communities that give us ideas and inspiration for our own projects. We will always provide our code, instructions, and other project files for free on the GitHub. This includes everything from Arduino code for the Bare Conductive Paint Piano to the laser cutting files for the wooden NES Controller. Follow us on social media and check back often for new projects!

Create Your Own

In the Development section of our GitHub repository you will find guidelines for creating new Crazy Circuits parts, as well a KiCAD library and template. These are intended to help you make any component you want into a Crazy Circuits Chip.

Technical Specs

The guiding factor in Crazy Circuits’ design is their compatibility with LEGO bricks. Through prototyping we determined that a hole diameter of 4.98mm works best with the 4.80mm LEGO studs. This size allows for slight variations in manufacturing due to the somewhat loose fit, and gives a tight connection when used with our conductive nylon tape. Crazy Circuits are Lead Free/ROHS Compliant.

Crazy Circuits Touch Board

The Touch Board measures 5x10 “LEGO studs” or about 4x8 cm. At the center sits a TeensyLC microcontroller, which allows the Touch Board to function as a USB Keyboard and enables capacitive touch sensing, without the need for a grounding wire.
• 20 Input/Output pins
• 20 Digital Pins
• 11 Touch Pins
• 8 Analog Pins
• 8 PWM Pins
• Two each of Ground, VIN, and 3.3V pins
