The purpose of building this circuit is to create a LED flasher with alternating sequence from the two LEDs where the operation is based on the functionalities of a 555 timer integrated circuit. 555 – ...

Unwieldy as it may appear, the LED flasher can be operated in the field by a team of just two people, meaning module testing can take place with the panels left in situ an attractive proposition for ...

The circuit in Figure 1 allows you to verify fiber-optic strands, especially in cases in which a link goes through several patch panels. It uses two high-intensity LEDs that you can see at the far end ...

Recently I converted the parking lights/turn signals and the taillights/turn signals in my 1956 Chevrolet to LEDs. The good part is they are really bright; the bad part is now the turn signals won't ...
