Here is a circuit that will output a PWM wave good for varying the speed of a DC motor. Why is this not going to work? How would you fix it? The 555 timer can’t handle that type of load, and it is not ...
Several years ago [Michael Davis] built a charge controller for his wind turbine and published his construction plans online. This build became quite popular, especially among people that live in ...
LEDs find their way into applications that range from high-end video displays to low-end lighting applications. Designers often need only some of the functions of a dedicated LED driver but can’t ...
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 ...
