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 – ...

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 ...

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 ...

This is a simple LED driver circuit using two 555s and a pair of NPN/PNP transistors to drive several LEDs meant to outline a small sign. Designed with my son for a St Patrick's Day project, in KiCAD.

This project demonstrates a simple LED flasher/blinker circuit using a 555 timer IC in astable mode. It's ideal for electronics beginners and includes PCB design files, a schematic, and a bill of ...

Three new Star Simpson’s Circuit Classics boards have arrived at the Adafruit online electronic store in the form of the Dual-LED Flasher, the Stepped Tone Generator, and the Bargraph Voltage ...

If you’ve ever been concerned about privacy in a rental space or hotel room, you might have considered trying one of the many “spy camera detectors” sold online. In the video after break [Big Clive], ...
