THE 555 FOR TODAY'S PROJECTS 
Become an expert on creating your own 555-based designs. 
 

In 1970, Signetics engineer Hans Camenzind designed the 555 programmable timer chip. Decades later, it’s still going strong as the world’s largest selling integrated circuit. I’ll explain the inner workings of the 555 and help make you an expert on creating your own 555-based designs.

YOU DON'T HAVE TO BE AN ENGINEER TO DESIGN YOUR OWN ELECTRONIC CIRCUITS

Do your own designs with a little direction.  

Most of you have at one time or another thought about designing your own electronics. The thing stopping many of you is the fact that you realize you’re not a “real” graduate engineer. Well, so what? You don’t have to have an EE degree to design. You can do your own design with a little direction. Here’s my approach to it, so you can give it a try.

LED CHASER/SEQUENCER CIRCUITS 
Light it up!

The LED chaser or sequencer is one of the most popular types of LED-driving circuits and is widely used in advertising displays and in running-light ‘rope’ displays in small discos, etc.

UNDERSTANDING HOW ELECTRONIC PACEMAKERS WORK 
See how to make things tick with this educational project. 

Get introduced to the field of biomedical engineering by learning the basics of how cardiac pacemakers work and seeing how to construct a primitive, functioning cardiac pacemaker using an Arduino microcontroller.
