Simple triangle-wave generators have a weakness in that the waveform of their output signal normally cannot be modified. The circuit presented here makes it possible to smoothly alter the waveform of ...

A solar generator’s capacity is measured in watt-hours, and it can give you an idea of how long you can power devices. Higher-powered devices eat up more capacity, thus draining the battery faster.

The circuit of Figure 1 generates sinusoids down to very low frequencies with distortion in the region of 3% or less, yet has no feedback or gain-stabilizing components because none are needed. It ...

This is a very simple square wave generator circuit built with IC 74LS00 that can generate square signals with frequencies between 20 Hz and 1 MHz. Its stability is good enough for most applications.

A portable generator is one of those things you don’t much appreciate until you need it, whether that’s during a blackout following a storm or when your devices die on a camping trip. Fortunately, ...
