This simple circuit generates narrow pulses at about 700-800Hz frequency. The pulses, containing harmonics up to the MHz region, can be injected into audio or radio-frequency stages of amplifiers, ...

I have wanted to make a pulse generator for years. I know you can buy perfectly good ones, but not if you want non-overlapping outputs to drive the mosfets in synchronous-rectified dc-dc converters.

The generator circuit was designed to produce alternating square pulses with vibrations in different parts of the circuit. 4027 – a dual JK flip flop that has independent clock, set, and reset inputs ...

For a long time, I have thought that pulse generator outputs should not have adjustable amplitude and offset. Instead, they should have an adjustable top value and a separately adjustable bottom value ...

When working with hardware, whether a repair or a fresh build, it’s often necessary to test something. Depending on what you’re working with, this can be easy or a total pain if you can’t get the ...

If you want to get your hands dirty on a semi-evil electronics project, this DIY EMP generator is fun—if not a little dangerous—build to try. It won’t fry much, except at extreme short range, so you ...
