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 ...

Used in a variety of timer, pulse generation, and oscillator applications, the 555 was designed in 1971 by Hans Camenzind. A favorite for many engineers, the 555 is still in widespread use due to its ...

In this project, I'll make a small circuit capable of controlling a servo, it is a servo tester made out of a 555 timer IC. In the process of making this circuit, we'll make a pcb design for it. This ...

The venerable 555-type timer makes an effective driver for power MOSFETs, but you have to understand the drive situation when selecting the correct variation of the basic timer. This idea shows how ...

Sometimes simpler is better — when you don’t need the the computational power of an onboard microcontroller, it’s often best to rely on a simple circuit to get the job done. With cheap Raspberry Pis ...
