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 ...

Yes, for me, it’s nostalgic to think about my favorite LED Driver LM3909 from NSC! This ubiquitous chip is very smart in that it stores up energy in a timing capacitor and then switches it in series ...

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 ...

They look for all the world like any other LED, though embedded in the plastic dome is an integrated circuit to do all that flashing work. There was a time though when a flashing LED was something of ...

LTspice is a free version of spice from Linear Technology, and it is delightfully easy to use, intuative, and seems to work rather well. Note, there is a flasher version 3 Current through component ...

It is a pretty common first project to use an Arduino (or similar) to blink an LED. Which, of course, brings taunts of: you could have used a 555! You can, of course, also use any sort of oscillator, ...

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 ...
