Introduction Consider you are in a research lab that handles highly hazardous material. You don’t want anybody to enter the room, to even come close to the door. Or consider yourself doing something highly confidential in a room that you would like to know if someone is trying to get in. In all these cases, […]

Chlorine damage a gasket on the robot and cause the shorts of the electronics embedded. It is obviouslly out of warranty, and the manufactuer does not send me any information to repair it, moreover a new board will cost me more or less like a new robot, cause i’ve to sent it to a certified […]

Introduction Our final project is to design and build a portable blood pressure monitor device that can measure a user’s blood pressures and heart rate through an inflatable hand cuff. The device is consisted of three main parts: external hardwares (such as cuff, motor, valve, and lcd), analog circuit, and microcontroller. The anolog circuit converts […]

Several months ago I noticed the Attiny88.  It has several more I/O than the Atmega328, with an extra Port A  and PC7.  And unlike most of the other Attiny series, it has real SPI instead of USI, so libraries using SPI don’t have to be re-written.  At just 86c for qty 1, it is the […]

Observing the quantum behavior of light is a big part of Alan Migdall’s research at the Joint Quantum Institute. Many of his experiments depend on observing light in the form of photons—-the particle complement of light waves—-and sometimes only one photon at a time, using “smart” detectors that can count the number of individual photons in a pulse.

1. Introduction Brian Smith and Cem Ozkaynak, two Seniors enrolled in ECE 476 at Cornell University, seek to rekindle the mood of impending nuclear annihilation by distant ‘Evil Empires’ through the classic 1980’s video arcade sensation Missile Command. Given the harmonious state of international affairs today and the resounding love for America throughout the world, […]

The Geostationary Lightning Mapper (GLM) instrument for NOAA’s Geostationary Operational Environmental Satellite – R (GOES-R) completed development and testing and is now ready for integration with the spacecraft. The GOES-R satellite will be the first flight of this sophisticated lightning mapping instrument in geostationary orbit and will enable early predictions of intensifying storms and severe weather events.

In a bid to bring affordable solar technology to the market by 2017, IBM Research and Airlight Energy (Switzerland) have partnered to produce a solar parabolic dish that can concentrate the sun’s radiation by 2,000 times and convert 80% of it into useful energy. The system is said to be able to generate 12 kW […]

Introduction    Our project is an autonomous toy car that tracks a high pitched audio signal. Using two microphones, a microcontroller, and two DC motors on an existing remote controlled car and, we implemented our own control logic to detect high pitched 3.5kHz audio signals and drive the car. This project consists of both software […]
