A toolbox dedicated to Magnetoencephalography (MEG) and Electroencephalography (EEG) data visualization and processing.
The system will test an individual's blood alcohol level by analyzing the breath exhaled into system, in which the sytem will decide whether to let the individual start the car.
transformer balanced input and output with amplifier in between.
If you need more sensitivity than the 5mhz circuit this circuit provides about ten times more gain. It too is designed around an inexpensive plastic optical fiber detector.
This circuit is a simple broad band light detector that uses a very inexpensive IC and a PIN photodiode
circuit attaches a plastic fiber optic PIN photodiode assembly to a small box containing a small 3v battery and a standard standard BNC plug designed to be plugged into to the input of an oscilloscope with a 50 ohm termination resistor, can detect light p
designed around an inexpensive plastic optical fiber detector and provides quite much gain
