Strictly speaking, a Theremin uses a pair of antennae that act as capacitors in a specific R/C circuit. Looking at ...

Little Laser Trip Wire circuit presented here can detect movement of people or objects while passing through the laser beam and trigger security alarms as alert signals to those concerned. What is ...

Their circuits are built from two laser beams, one that creates a horizontal sheet of light to act as a circuit board, and another vertical laser that traces out the path of the circuit.

Newport has developed a diode laser current driver circuit with noise characteristics that it says are as much as 10 times lower than currently available.

Recent projects that used inkjet printers to print multi-layer graphene circuits and electrodes had the engineers thinking about using it for flexible, wearable and low-cost electronics.

Networking specialist ADVA has joined an initiative that aims to speed up data center interconnect (DCI) technology by embedding lasers into silicon chips. The four-year collaborative project, called ...

As demand for next-generation semiconductor chips grows, a team of researchers has succeeded in laser-drilling the world's tiniest circuit board holes, measuring a near-inconceivable 3 micrometers ...
