Adding a remote control switch to nearly any project is easy with these small keyfob-based RC relays. They are very inexpensive (<$20) and offer such options as MOMENTARY and TOGGLE operation as well as multiple relay channels to control. However, from what I found, these units require 12VDC to operate properly. This article explains how […]
My cats like to jump on furniture and shed their fur, which ends up on my clothes. To stop them, I’m using a Monkey Couch Guardian. I made it from one of those old-fashioned cymbal-banging toy monkeys, modified with an inexpensive Arduino microcontroller and a proximity sensor. Now when a cat jumps on a table, […]
Connect a shirt pocket “amplified listener” hearing aid with an in-car FM transmitter, and you’ve got a wireless bug. Tuck them inside a hollowed-out book with the mic concealed by the dust cover, and you’ve got a covert listening device that you can leave lying around or on a shelf near a surveillance target. Then […]
In this project, we’ll turn a MAKE MintDuino microcontroller and a Mintronics Survival Pack into a replica of retro electronic memory games like Simon and the Tandy Pocket Repeat game sold by RadioShack in the 1980s. It’s amazing how fun and addictive this simple game is, and it’s a great way to learn about integrated […]
Last year we ran a cool CoasterBot build project and contest on MAKE. We had dozens of awesome entries, from the most basic to the quite elaborate. This Make: Project shows you how to make just about the simplest CoasterBot imaginable. From here you can add new sensors and features and build on the basic […]
The Luna Mod is an easy and fun instrument that will have you making great-sounding loops in no time. Rather than sampling input like a traditional loop station, the Luna Mod synthesizes its own sounds, and you play it using two knobs and one button.
