A simple fm radio transmitter circuit which covers frequencies from 88 to 108 MHz. It is built with 3 transistors: BC109, BFR91A and BFR96S. It is quite stable and the output power is around 200 mW.

This sensitive FM radio tuner is the right circuit for hobbyists who want to build their own tuners instead of buying a “plug-n-play” finished product. The fm tuner circuit is designed with only 3 ...

A team of biologists and engineers has developed a 'rapid and tunable post-translational coupling' for genetic circuits. Programming living cells offers the prospect of harnessing sophisticated ...
