The OriginsWhen we decided to throw a party in LA (which became know as The Gathering) I wanted it to be more than just free t-shirts and beer. Laser Graffiti popped to mind and I was glad that Ben was willing to take the lead on that project....
Arduino reads voltage from voltage divider with standard 10k resistor and NTC. Breathing causes NTC to change resistance which leads to voltage changes on divider. ATmega328 in Arduino reads voltage with ADC and passes data to LabView function. Function...
For a while had been wanting to experiment with having touchscreens around the house to add more home control options to a location. Having a smartphone and older iPod touches used as remote controls, I knew they aren't always within reach or easily...
GoalsThe goal of this project is to emulate the Canon 600EX-RT Speedlite (via it's IEEE 802.15.4 protocol) and interpret the commands from Canon transceiver so that the Paul C Buff - Einstein light can be controlled with the Canon gear.CyberSync CSXCV...
Mooltipass is composed of one main device and a smartcard.On the device are stored your AES-256 encrypted passwords. The smartcard is a read protected EEPROM that needs a PIN code to unlock its contents (AES-256 key + a few websites credentials). As...
So my son, [B] did the soldering work. His uncle help him mill out the inside of the car to fit the electronics. [B] Drilled the holes for the lights and then painted the car with little sisters help. We tested the code on the MSP430 launch...

A bendulum is topped with a weight. If you give the top a push, it sways back and forth periodically. The motion is much like a pendulum, except that instead of swinging rigidly from a pivot and moving the most at the bottom, the bendulum’s stem flexes...
I've done this project twice. The first keyboard completely died shortly after I made my spare. Unfortunately the new one's USB hub is less reliable. The keyboard doesn't get activated soon enough to send keypresses during booting... I've been...
IntroductionVaporization is done by off-the-shelf ultrasonic atomizers, either really cheap ones (the black ones in the picture below, 2.50 $ each) or some more rigid ones (the silver one, a Fogstar 300, 290 € each), air is moved by an array of...
