Interfacing a RC radio to a microcontroller is a bit of a pain, especially if you want a lot of channels, because you have to time each channel’s output individually. An AVR only has one 16 bit timer with two compare channels, so either you can only use two channels at full resolution or you […]

About this project The Qduino Mini is perfect to embed in your electronics projects, it’s super small, inexpensive, has a battery connector & charger built-in, & a fuel gauge that can tell you when to charge the battery! The Qduino Mini is Arduino-compatible & 100% open source, hardware and software meaning that making and programming your […]

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 […]

In this instructable the main focus lies on the software which I’ve created – not so much on the hardware side. You needn’t to use a high- power led for this, you can use every RGB- LED you like. The “High Power RGB LED Moodlamp” is a high power rgb led lamp which can be […]

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, […]
