Time for something a little more advanced. Direct Port Manipulation. Normally when using Arduino software, the actual logic behind changing the values in pins is abstracted away with digitalRead and digitalWrite. Now, for most people that’s just fine. But it has some limitations. For one, it is a little slower than might be practical for […]

This head is a reading lamp which can be adjusted for direction of lighting, and dimmed as required. This Instructable combines Arduino programming, some simple electronics, carving with hand and power tools, mechanical control and a bit of woodwork. Apart from the Arduino and a few components it is mostly made from reclaimed materials. I

This guide details how to build a simple electricity energy monitor on that can be used to measure how much electrical energy you use in your home. It measures voltage with an AC to AC power adapter and current with a clip on CT sensor, making the setup quite safe as no high voltage work
How to build an Arduino energy monitor – measuring mains voltage and current Continue Reading
This is a Modification of an electric wheelchair. I called it “Buggy” for two reasons. #1 My kids can still ride it around because I left the seat intact. #2 I haven’t programmed anything for a long time. I plan to create “jobs” for it in the near future. I welcome any input. Keep in
FOBO is the fourth prototype from Project Biped. It is a 3D printed, self-contained, statically balanced, bipedal robot. It has 8 DOF (degrees of freedom) and can walk around its environment and avoid obstacles using an ultrasonic range sensor. All of the designs, instructions, source code, and parts lists are provided for free. FOBO was

I have watched the availability of high power (>10W) LED’s jump over the past year or so and… drop in price. I came across some very inexpensive 10W white LED’s from Deal Extreme that were in the $3 dollar range and put out 900lumens, which is more than a 60W incandescent bulb. I immediately thought

A homemade thermostat attachment for a crock pot (or other electric heating device). It can be used to precisely control the temperature of the crock pot for things like yogurt fermentation. Why Making yogurt is fun. It is also way cheaper than buying it. You can make yogurt on the stove or in an oven,

The CatBot is an autonomous laser toy for your cat. You may say “But Joe, isn’t the laser pointer the best toy for the lazy cat owner?” I’d have to say no, the CatBot takes one step further. Using two servos, an Arduino and a cheap $3 laser you can provide your cat with endless

Introduction: As a group, we feel that everyone should be able to enjoy the things they love to do despite their limitations. Our project is designed to enable people who are unable to use their legs to operate the pedals of a piano and to be able to do so by simply attaching a

The Luna Mod Looper, basically lets you record a sequence using a potentiometer to control the pitch of the note, and then play it back and add affects. Ever since I saw videos of the Luna Mod being played, I wanted to build my own. However, the project required a picaxe microcontroller, which I have
