Assembling tiny SMD components by hand is one of the most challenging parts of PCB manufacturing. Some components, especially 0201-sized parts, are so small that accurately placing them with tweezers ...

KISS FFT converts a time-domain signal (a series of samples from a microphone, ADC, accelerometer, etc.) into the frequency domain, revealing which frequencies are present and how strong each one is.

Tony Goacher] has worked with a lot of cheap brushless DC motor controllers built in China. They can be very cost-effective, ...

There are plenty of radios you can buy that pick up MW and SW bands if that’s what you’re into. Or, you can follow [mircemk]’s example, and whip one up yourself instead. The build employs an ESP32 as ...

Frequency combs are light sources with a spectrum that comprises a series of sharp, equally spaced lines. The frequencies of these lines are known to a very high degree of accuracy, which makes ...

f = frequency = number of waves produced by a source per second, in hertz Hz. T = period = time it takes for one complete vibration or oscillation, in seconds s. A boat at sea bobs up and down as ...
