DiSEqC-Tester allows to test DiSEqC-Switches that uses 1.0 or 1.1 protocols. (DiSEqC-Switches with 2.0 and 2.1 protocol have backwards compatibility with 1.0 & 1.1 respectively and also may be tested). The device every second sends command “Switch next port”. [more]
The PSoC Range Finder is a simple, inexpensive ultrasonic distance meter that requires only the PSoC device, two 40-kHz ultrasonic transducers, two resistors, and two capacitors. Typical applications include positioning for robotics, generic distance measurement, and liquid-level measurement without contact. [more]
This project is a 2 channels amp meter. Those channels are completely isolated up to 2000 volts.It provides auto detection for AC or DC current. The main part of this project is the current sensor ZMC10 a cool DIP 14, which supports up to 10 A. The current is measured inside by hall effect sensor and display data using a graphic LCD of the read current and max peek value, DC or AC [more]

This device is a small monitor attached to the hand, which can be worn 24 hours a day for continuous monitoring, strikes us as having the potential for extreme usefulness. The monitor works differently than regular old blood pressure cuff, using a method called pulse wave velocity, which measures the pulse at two points along an artery. Built by a team of engineers at MIT.The team’s first project was a ring that measures pulse rate and the amount of oxygen present in the blood. After developing the ring, Asada decided to move on to blood pressure sensing, which offers even more valuable information about a patient’s health.[more]
TiltStick is a small acceleration sensing device in form of a USB stick. It’s using a two axis acceleration sensor to measure acceleration (caused e.g. by motion and tilt). The device is emulating a USB joystick and can thus be used in conjunction with any USB equipped host (e.g. a standard PC or the Nokia N8XX family) without any special drivers. [more]
