LED flasher circuit 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 ...

how does the 555 flasher circuit works? The IC is connected as a astable multivibrator with a duty cycle of about 10%. In figure 1 the LED will be ON for a short period of time and OFF for a longer ...

Even though there are other ways to blink a LED and other ways to make an oscillator, [Eric]’s circuit is about as simple as it gets. [Thanks, fede.tft] ...

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 ...

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 ...

This is a very simple but useful project, strobe navigation lights for rc airplanes, or you can adjust the flashing time and ...

BMW LED turn signals review.Replacing the Stock Bulbs Replacing the stock Osram 5009 amber 10W bulb — at least on the F 800 S — is a piece o’ cake. Remove the one Phillips head screw in the rear of ...

Figure 2 shows the current-voltage waveform of the circuit. Here are a couple of other examples. For a 5-V, ±5% monitor, set R1 = 121 Ω and R3 = 301 kΩ.
