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 ...
Well, here’s a cooooool finding. Take any piece of electronic equipment you can think of and its circuits are powered by, yes, electrons. But a new experiment takes us one step closer to “atomtronic ...
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. The company also claims that the circuit ...
Kirchhoff's current law has been rewritten thanks to a three-port transistor laser developed at the University of Illinois, US. While the laws of physics weren't made to be broken, sometimes they need ...
A while ago, [Marco] mounted a powerful laser diode to a CNC machine in an attempt to etch copper clad board and create a few PCBs. The results weren’t that great, but the technique was promising. In ...
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 in ...
Scientists at EPFL and IBM have developed a new type of laser that could have a significant impact on optical ranging technology. The laser is based lithium niobate, often used in the field of optical ...
[Ben Krasnow] over at Applied Science was experimenting with cutting inexpensive ceramic sheets with his cheap CO2 laser cutter when he found that (just as expected) the thermal shock of the CO2 beam ...
Researchers in Oxford have demonstrated a chip-scale trapped-ion quantum logic IC that works with all-electrical drive and a magnetic field. Because it avoids the need for per-qubit lasers, it is more ...
