The real core of engineering, in addition to technical expertise, is the ability to articulate the inevitable tradeoffs and pros/cons of design alternatives, and then weigh these relative to each ...

The design features a 555 timer simple application in which it manipulates the sequence of LED lighting. It is a low power that can last longer even with small energy source. The design features a 555 ...

Time will always be“of the essence” for professional engineers and amateur enthusiasts alike. This can certainly be said about the process of designing circuits involving Light Emitting Diodes (LEDs).

This custom circuit board picks up some of the pieces from a wall wart to drive a high-power LED. The basic concept is to keep the high-voltage components and swap out the low voltage ones for parts ...
