You can create a release to package software, along with release notes and links to binary files, for other people to use. Learn more about releases in our docs.

“Instead of an Arduino, he could have done that with a 555 timer.” “Instead of a 555 he could have done that with two transistors.” “Instead of a few transistors, he could have done that with ...

From simple buzzers to an Atari Punk Console, the simple 555 timer chip is the foundation of a whole lot of interesting lo-fi synth projects perfect for beginners. [Steven] put together a great ...

In this list, we present a collection of exciting 555 Timer Projects that harness the power of the 555 Timers to create a diverse range of electronic devices and circuits. The standard 555 timer IC is ...

This project details the construction and observation of a simple crystal oscillator circuit designed to generate a clock signal around 16 MHz. The oscillator is built using a 16.000 MHz crystal, a ...

Whilst developing a simple scanning receiver, a need occurred for a ramp generator to provide a varying voltage to apply to the varicap diodes fitted to the variable frequency oscillator (VCO).

This Design Idea demonstrates a simple way to generate a multiphase clock signal, the frequency of which can be varied with minimal change in phase shift(s). The phase shift of the second output can ...
