If you don’t have any bomb-sniffing bees around to look for trance quantities of explosive gas, why not use your iPhone instead? That’s exactly what Jing Li and a team of researchers from NASA have done with their cell phone chemical sensor.
From the MAKE Flickr pool Charles is using an Arduino ethernet shield to send the rhythm of his heartbeat over a network in the form of OSC messages. Each beat is detected via a simple sensor comprised of an IR LED and phototransistor – The idea is that when your heart beats you have a […]
Aaron ALAI’s EMF detector project looked so simple and fun I had to give it a try!
This looks pretty interesting. Just got this info from Parallax PR: The CO Gas Sensor Module is designed to allow a microcontroller to determine when a preset CO gas level has been reached or exceeded. Interfacing with the sensor module is done through a 4-pin SIP header and requires two I/O pins from the host […]
Built with the LEGO NTX platform (plus PDA support processor), the Sundial Robot uses sensor data to calculate time of day the new/old-fashioned way – In operation, the robot rotates 360 degrees to calibrate the Compass Sensor. It then rotates in 5 degree increments, the light sensor is swept from vertical until the Touch Sensor […]
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 […]
As part of her research at the MIT Media Lab, Anita Lillie did some investigations of her own sleep habits recording motion sensor data via Arduino – I outfitted myself with sensors that would help me determine how my position changes over the course of a night’s sleep. I used three accelerometers as tilt sensors, […]
