Physicists at Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have created a compact laser that emits extremely bright, short pulses of light in a useful but ...

This circuit is very useful while checking/operating counters, stepping relays, etc. It avoids the procedure of setting a switch for the required number of pulses. By pressing appropriate switches S1 ...

Picture a beaded string curtain, but one in which every bead is a tiny light, called a “voxel” or “LED neuron.” By switching these lights off and on in different combinations, the bead curtain becomes ...

When you need to create simple pulses and don’t have a pulse generator, you can often substitute a function generator. By using a function generator’s triggered burst function, you can create pulses ...
