[Bob] has been busy lately putting the finishing touches on three different projects that he plans on entering into the 555 Design Contest. His first entry is a low-power H-bridge, which can be used ...

One of the most common clichés around here is that a piece of equipment chosen for a project is always too advanced. If a Raspberry Pi was used, someone will say they should have used an Arduino. If ...

In this project, I'll make a small circuit capable of blinking lights, on its output we get a digital signal that we can use to turn on and off an external light like an LED. This circuit uses the ...

In this project, I'll make a small circuit capable of controlling a servo, it is a servo tester made out of a 555 timer IC.

The project was designed to build a frequency generator based on 555 timer that can be used as a body zapper. The project was designed to build a frequency generator based on 555 timer that can be ...

Anyone who has designed circuits using the 555 timer chip will, at some time have wished that it could be programmed for longer timing periods. Anyone who has designed circuits using the 555 timer ...

This file type includes high-resolution graphics and schematics when applicable. Paul Rako, Creative Director, Rako Studios Back in 2011, Jeff Hamilton contacted Bob Pease, asking for Bob’s experience ...

The 555 timer IC has been reinvented—again. Signetics introduced the enormously popular chip back in 1971, and it quickly became a big hit. Myriad application circuits have used it throughout the ...
