Todbot makes an interesting suggestion Analog meters are hard to use in hardened environments. If you’re showing data from digital sources, why not use a digitally-controlled analog meter? laser cut acrylic meter face & needle, tiny 25mmx12mm $3 servo, and arduino. – Servos as meters on Flickr MotorShield for Arduino Kit
An Arduino, model bulldozer, servos, and sensors can be hacked together to make a sub-$100 robotics platform, appropriately named Ard-e. While certainly nowhere near as fancy as this Wall-E replica, the price is right and the Arduino’s got a huge body of pre-existing code for working with sensors that the aspiring roboticist can build upon. […]
From the MAKE Flickr photo pool Flickr user [fluxa] put an Arduino board to work outputting control voltage to a DIY SoundLab synthesizer. While the PC software has yet to be released, the Arduino code is pretty straightforward – using a pulse width modulated output through a simple resistor/capacitor filter. – CVAirSequencer Project on Flickr […]
Kyle writes – A friend of mine wanted a bitcrusher/samplerate reducer pedal for his guitar — I thought “you could probably do that with an Arduino”. The quality turned out surprisingly reasonable. I’ve released the code, which sets up the pins on an Arduino for doing 10-bit DSP at reasonable sample rates The design includes […]
Instead of waiting around for a faster Arduino to be released, Zach of NYCResistor is developing his own – I’m in the process of porting the Arduino environment to the atmega644 for a skunkworks project I’m working on. This chip is awesome because it has 4x the flash (64k vs 16k) it has 4x the […]
Dhananjay Gadre wrote in from New Delhi with news of “GuGaplexing”, an update to the tried and true technique of Charlieplexing. GuGaplexing introduces a set of transistors into the mix to double the number of LEDs you can address: The transistor pairs are so arranged that they provide an out of Vcc/2 at the output […]
Here’s a helpful library that allows one to add simple IR control to projects The library implements the NEC IR protocol, so set up the universal remote for any NEC device (TV, DVD, VCR, …) and the 32-bit codes should be received. The example sketch provided just prints out IR codes as they’re received, so […]
