[Bob] has been busy lately putting the finishing touches on three different projects that he plans on entering into the 555 Design Contest. His first entry is a low-power H-bridge, which can be use… ...

The 555 timer IC remains iconic and widely used. Let's explore its enduring appeal through simple, fully tested 555 projects. No programming required!

[R-B] designed a 555 timer circuit to scan a keypad. Keypads are common interfaces for small projects and require row and column scanning by a microcontroller. [R-B’s] setup allows you to reduce ...

If you survive… look forward to more unreleased 555 timer projects from me, such as: A 555 timer-based human heart pacemaker A 555 timer for a spinal-cord RC-controlled rabbit ...

A timer-controlled doorbell device has been developed using two 555 timer ICs in monostable mode, combined with a relay ...

Chris Gammell from the blog The amp hour and Analog Life is running a 555 timer IC design contest. EDN’s Mike Demler wrote it up on his blog yesterday. So Mike or Chris asked me to do a mention on ...

An astable 555 multivibrator circuit, where the timing characteristics are determined by the interplay of an inductor, resistor, and diode.

Hans Camenzind is well known for the design of the 555 timer, but he accomplished much more in his lifetime. A restless entrepreneur, he was constantly looking for the next project that would keep ...
