Arduino Fuel Gauge: A few months ago, I hit a pot-hole while driving my 1974 Dodge Dart and my fuel gauge immediately went to “E.” For a split second I thought I lost all of my fuel! My father-in-law suggested I drive backwards over the pothole to fix the gauge. It didn’t work. I researched […]
Assemble the Supercap Racer kit and make a new toy that’s fast, unpredictable, and fun to build.
Build a pulse-sensing headband that flashes an LED array in time to the beating of your heart. You’ll scratch-build your own perfboard Arduino, assemble the Open Heart LED display, and learn how to use the AMPED pulse sensor. It’s the next best thing to wearing your heart on your sleeve.
This year I decided to opt out from the boring practice of buying standardized Halloween costumes for my kids and instead build costumes myself. This Instructable is for the one I built for my son. I hope it is interesting not only because it is cool and unusual, but also as fun reading about different […]
This project requires knowledge of woodworking, metal working, simple electronics, and access to a lot of parts. It runs off a battery and CO2. The CO2 tank is carried in a rolling backpack. A quick-release hose connector permits the gun to be carried without a tether, and allows quick CO2 tank swaps as needed.
This guide will describe the steps required to build Skull Ball, a DIY interactive game using a teensy microcontroller and a Sharp IR sensor to count ping-pong balls being thrown into a plastic cup mounted in a plastic skull. I built this project in about 5-6 hours the week of my company Halloween party as […]
For this variation on the original Trippy Nightlight an inexpensive (> $2.50) USB AC charger provides a traditional nightlight plug-in-the-wall form factor. To simplify the main circuit board I removed the download circuitry from the board and instead programmed the PICAXE 08M microcontrollers on a separate breadboard. Instead of a quartz crystal, two Jell-O snack-size […]
