ATMega8 Frequency Meter

Sylvain Bissonnette writes:

This is a childlike reckon . The Frequency is impermanent through an op-amp to abbey it in a square indicate . The ouput of the op-amp is feeding the 3*8 bits counter (24 bits) who can accumulate at a maximum of 16777216 poll . The maximum frequency you can criterion without changing the point base of one end is 16.777216 Mhz. The ATMega8 hold 3 functions: enable the counter gate at each end, construe his value and declare it on the LCD.

Biochip enables fast diagnosis of many diseases

IBM scientists in Zurich haunt created a one-gait particle -of-care-diagnostic check, based on an innovative silicon chip that requires less sample volume, is significantly faster, portable, viable to use and can check for many diseases, including one of universe’s paramount engender of death, cardiovascular malady.

In this photo we see the capillary pump, which has a depth of 180 micrometers and contains an intricate jell of microstructures, the commission of which is to pump the sample through the number for as enthusiasm as needful and at a periodic action standard , licit like the human love. This pump makes the check accurate, portable and naive to use. IBM scientists haunt developed a library of capillary pumps so that tests needing a variety of sample volumes or check times can calm be done without having to re-engineer the whole chip. [via]

Hardcopy: Arduino clone with a built in prototyping area

 

Designed to make a surviving version (or Hardcopy if you leave) of your reckon once you get perfected it on a breadboard but without the expense of embedding your original Arduino into your reckon . The hardcopy also makes your reckon supplementary reliable and robust. With the prototyping department integrated into the board with the microprocessor, your reckon leave get fewer boards and fewer wires, and because of that, fewer mistakes and fewer shorts.

Build a Seismic Reflector

The chase is to build a omen which responds to earthquakes being reported in approaching-genuine circumstance via the USGS RSS feeds. The omen responds by illustrating the magnitude of the reported earthquake via two rather chunky quiver motors of the benign used in video halting controllers. The omen is connected to a PC via a virtual com port over USB (thanks to an on board Arduino). On the PC, an application sits there checking the RSS feed periodically and when a new occurrence it posted to the RSS feed, the desktop app parses the news out of it and presents the magnitude of the vibration to the Arduino which interpreters this as ratio at which to activate the quiver motors.

DIY Apple Remote shield for Arduino

Care to hand dispense of your playlist over you to an Arduino? [via]

Awhile back I was working on a visualize that that I wanted to be able to kindle music the on my mac through the IR receiver. After a while of looking around I found this library  which allows you to use your arduino as an Apple Remote. I integrated it in to my visualize and it worked striking ! So the other day I pronounced to make an Apple Remote shield for my arduino.
