[mircemk] notes that the circuit would be more versatile with ... It’s probably not the most accurate frequency counter out there, and you’d probably want to calibrate it using a known-good ...

There’s a transformer for the linear supply, through-hole components, and an Intersil frequency counter on a chip. Everything is easy to get to and large enough to see.

Photonic technology can now be used to construct miniature sources of high-frequency radio waves that have exceptional spectral purity. In the early 1980s, researchers at NASA's Jet Propulsion ...

The allele frequency represents the incidence of a gene variant in a population. Alleles are variant forms of a gene that are located at the same position, or genetic locus, on a chromosome.

In the latest round of blasts, exploding walkie-talkies killed 14 and injured at least 450 people, according to Lebanon's ...
