This simple Mock Flasher LED simulates the indicator of a sophisticated Alarm system. It can be placed in doors, gates and vehicles to confuse intruders. The circuit is too simple using a Unijunction ...

This is a small size led flasher built with the 555 timer IC that is powered from 2 x 1.5V batteries. The circuit can be used as a flashing metronome, dark room timer, memo-reminder or other similar ...

An LED is commonly used as a "power on" indicator for many electronic devices. For the LED to produce discernible visible light in daylight, the forward-bias current needs to be in the moderate range ...

Maybe I shouldn’t be surprised, the led flasher modelled in LTspice works, just about as intended – nice crisp flashes at about the right rate. Seeing as everything is relying on Vbes and Vfs, the ...

Bypass diodes: The Zurich University of Applied Sciences has developed a new mobile LED flasher that can test module nominal power in the field, rather than in the lab. This flasher can also detect ...
