Sure you can use LDR’s, potentiometers and buttons to generate sounds, but what about strings? When I began thinking about an Arduino string instrument, I realized what I wanted to create was a soft potentiometer. I found my inspiration from Hannah Perner-Wilson’s Fabric Potentiometer http://www.kobakant.at/DIY/?p=543. Step 1: Parts Step 2: How it Works Each string is […]

Working with the interaction design team, a bunch of us at Teague have been tinkering with measuring water, analyzing usage data in realtime to affect behaviors, and storing it to see patterns over time. At the heart of the exploration was a need to cheaply measure water from the tap. Water meters vary quite drastically in price

Have you ever wanted an ultrasonic tape measure, like this Stanley? (See picture). Well, I have but then I am a Lazy Old Geek. I don’t really need one but I thought I’d try to make one. And naturally, I thought of an Arduino. August 2012 update: I just found out the software used in

This Frankenstein Laser Cutter was built out of an old scanner and printer. The whole thing evolved around the instructable of Groover and his ‘Pocket Laser Engraver’. This is a Making-Of. Although a lot, if not everything, of the mechnical construction requires ingenuity I tried to document the complete build process as much as I

This is my first in a series of more advanced Arduino tutorials. Now that we’ve covered the basics in tutorials 1-10 (you have watched them all right!?), it’s time to start pursuing some more complex projects! In this episode, we’ll utilize an SD card shield from cooking-hacks.com to create a datalogger. First, I’ll walk you

The Memsic 2125 (datasheet) is a two-axis accelerometer capable of measuring acceleration up to plus or minus 2g. It has a simple digital interface: two pins (one for each axis) emit pulses whose duration corresponds to the acceleration of that axis. By measuring the length of that pulse, in microseconds, using the Arduino’s pulseIn() function,

After a break of around two decades I’ve recently started building a model railway. One of the issues I’ve faced is trying to work out how fast I should be running the trains so that their speed reflects reality given the scale at which they are modelled. I’m guessing the details won’t interest everyone reading

Recently I was reviewing one of my oldest project, and decided to “refresh” previous design by taking full advantage of the new arduino Leonardo board. Based on AtMega32U4, which include PGA (programmable gain amplifier), oscilloscope’s analog front end doesn’t require external OPA this time, end could be build in 1-2 hours on prototype board, using

Have you ever wondered how migratory birds manage to have such an amazing sense of direction despite being so generally clueless? They can sense the Earth’s magnetic field with what is basically a compass built into their body. Wouldn’t it be cool to feel what that’s like? The following instructions are loosely based off of

Have you ever wanted to, without going out of your way to clock your processor, see how much stress your computer is under? With this project you will have a simple bar graph that constantly shows how much stress your computer is under. If the graph reads 0, your computer isn’t working too much. If
