The great thing about building with gates is the crazy speeds you can achieve by using hardware directly (as opposed to working with simple microcontrollers). This 100 MHz frequency counter is a great ...

New software from Tenna Systems maps out the interference landscape by assembling telemetry data from existing radios, and allows jammers to be avoided — or targeted.

The Model 1856D, a lightweight frequency counter from B+K Precision, performs frequency measurements from 0.1-Hz to 3.5-GHz and can be used in both lab and service settings. The unit measures RPM and ...

The prescaler described here connects to the front end of a 100-MHz frequency counter to extend its coverage range to 10 GHz. The circuit is a far less expensive way to measure frequencies above 100 ...

Sometimes when you build something it is because you have set out with a clear idea or specification in mind, but it’s not always that way. Take [kodera2t]’s project, he set out to master the ATtiny ...
