LED chaser lights (or) sequential LED flasher circuit on a breadboard using 555 timer + 4017 IC and a few other components. The LED’s chasing rate can be adjusted using a potentiometer in place of 47K ...

A transistor tester can be a handy addition to your electronics workbench. This versatile transistor tester design, first presented a decade ago, enables you to quickly assess the functionality of NPN ...

It is often the case that you don't have all the components required to build a circuit that is developing in your mind. Or, perhaps the circuit you wish to develop uses dangerously high voltages and ...

[Collin Cunningham] over at Make recently wrapped up another edition of “Collin’s Lab” – this time around, the subject is breadboards. He starts off by discussing a common solderless breadboard, ...

Over the last year, the production of homebrew electronic badges for conferences has exploded. This is badgelife — the creation of custom hardware, a trial by fire of manufacturing, and a mountain of ...

Well, I must admit to being flabbergasted. I think I can say without fear of contradiction that my “flabber” has rarely been so “gasted.” The cause of my current state-of-gast was the rapturously ...
