ANALOG AMP METER CLOCK- An Elegant timepiece marks the hours with needle meters – By Gene Scogin… Several years ago I had the idea of making an analog clock that used voltmeter-style needle gauges rather than a standard dial. A few weeks ago I finally made one, using an Arduino board and 3 current meters […]
Make a device that identifies dangerous liquids by analyzing light – By Eric Rosenthal… After air travel security banned bottled water and baby formula, I began wondering why they didn’t use a device to determine the contents of liquids. If a liquid was detected to be safe, security could allow it on the plane. Spectrometers […]
Yesterday afternoon, a whoop of excitement resounded throughout the Maker Shed — currently under construction at Maker Faire Austin — as we cracked open boxes of Getting Started with Arduino, fresh from the printers. There’s nothing that beats that feeling of seeing the results of so much hard work and devotion in physical form. The […]
From the MAKE Flickr photo pool If you should accidentally disable the reset pin while programming an AVR chip, you’ll lose the ability to rewrite to it using common ISP programming devices. To make the chip writable once again, you’ll need a ‘high voltage programmer’ that runs off of 12V. With an Arduino and some […]
Create Digital Music’s Michael Una posted a nice roundup of Arduino sound synth projects, including Octopusss circuit bend seen above and even one from myself :) There’s definitely a lot of interest interest in this area of Arduino dev, which makes sense considering the platform was developed with artists in mind. I’m sure we’ll be […]
Bit-music loving Arduino users – I ported (and modded a bit) one of the Noise Toy programs over to the lovely and talented Arduino platform. Just add a couple of momentary switches to pins 8 and 9 and connect stereo audio to 3 and 4 – you’re done. Loud Objects’ code proved quite fun to […]
Arduino polishes up its navigation skills via an inexpensive compass sensore component – A small digital compass based on hall effect is connected to an Arduino 10000 board. The logic in the board turns on and off leds depending on direction. There are 4 leds, one for each in N,S,W,E. When two leds are ON […]
