I love LED chasers. A bunch of LEDs neatly turning on and off on a precise timing – lights running one way, then the other way… It’s relaxing, soothing, and hypnotic. There are so many LED chaser/scanner/sequencer circuits out there; some are made with discrete transistors, some based on logic ICs, and more and more […]

The kit contains the electronic parts required to make a drum kit. This includes the circuit board, resistors, diodes and pins. You supply the Arduino and the material to make the actual drum pads. Below you will find easy instructions for making traditional-looking drum pads, but you could also stick the piezo elements (the parts […]

LED throwies are cheery glow-dots you can make in seconds from simple components and stick to any ferro-magnetic surface. But that’s just the beginning — here’s how to hack and modify them. First make a basic LED throwie, and chain them up into big throwie “bugs.” Then learn to hack the throwie with an On-Off […]

This word clock has a lot of small steps that add up to a moderately difficult build. You’ll be building three circuit boards, possibly making (or modifying) a frame, soldering SMD parts and playing around with finicky die-cut stickers. However, the end result can be very satisfying. If you’re concerned about doing some of these […]

The Mintronics: Menta is a unique Arduino-compatible microcontroller kit. It features a handy, on-board prototyping space and is specifically designed to use the included mint tin as an enclosure! This makes it perfect for logging applications and on-the-go development. The prototyping area is perfectly sized for one of our mini breadboards (not included) so you […]

Crystal radio technology has been around for many years. This “bottle radio” take on a crystal radio requires no power source, operates on the power from radio waves, and receives signal from a long wire antenna. As radio stations slowly move away from the AM band, the “window of opportunity” to experience this remarkable technology […]
