Researchers from Rice University have recently published the results of their work on graphite-based mass data storage and reprogrammable gate arrays in a major step towards making graphene-based ...

OAK RIDGE, Tenn., August 27, 2010 -- Technology developed at the Department of Energy's Oak Ridge National Laboratory that extends the life of light-emitting diode lamps has been licensed to LED North ...

A modification of the current-control circuit in a low-voltage LED system allows use of a chopped supply voltage to modulate the LED intensity. The circuit prevents inrush current to the decoupling ...

Given the low costs and extensive applications that could be possible with flexible paper circuit boards, we've seen many ideas for their production, from printing with silver ink to embedding chips ...

Frank Hertel’s project: three individually dimmable LED lights. (Frank is the master of recycling; the wooden mounting pedestals are the panels from a decommissioned ATI console!) Thanks for your ...

This is a very simple LED dimmer circuit which has 2 transistors, 1 resistor and 2 potentiometers. Typical segment displays LEDs consume around 25 mA for each segment and should be limited to this ...

LONDON (Alliance News) - Graphite exploration company Stratmin Global Resources PLC Thursday said it has completed of the first full shift of production using its new processing circuit and has ...
