Some 1.5 v LED flasher circuits are available on the internet and we like to present you four of them. The flasher circuits below operate on a single 1.5 volt battery. The circuit on the upper uses ...

This circuit was designed to provide that continuous light lamps already wired into a circuit, become flashing. Simply insert the circuit between existing lamp and negative supply. Especially suited ...

[Eric Wasatonic] had a box of SWB2433 transistors that he had very little information about. In order to discover their properties, he fired up his curve tracer to compare these transistors with more ...

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 ...

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 ...

A $246.00 LED Replacement for Four $1.81 Bulbs? Why Not?! So all of you cheap BMW Airhead guys who visit a junkyard just to grift a valve cap from a wreck because 25¢ for a new one is too much — this ...

With cycling safety in mind, I bought a pair of low power red LED things that replace the bungs in the end of drop handlebars. They are a neat way to get a bit of extra visibility – and to give a ...
