This stunning piece of art is [Emily Velasco’s] take on the Atari Punk Console. It’s a freeform circuit that synthesizes sound using 555 timers. The circuit has been around for a long time, but her ...

在非稳态555多谐振荡器电路的经典配置和大多数变体中，定时特性都是基于电容器的充放电。不过，可以认为，由于电容器的指数电压与电感器电流在性质上相似，因此后者可以作为555的替代定时元件。 在非稳态555多谐振荡器电路的经典配置和大多数变体中 ...

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 ...

In the classic configuration and most variants of the astable 555 multivibrator circuit, the timing characteristics are based on the charging and discharging of a capacitor. However, it can be argued ...

The 555 timer IC is an integrated circuit (chip) which is used in a variety of timer, delay, pulse generation, and oscillator applications. 555 Signals and Pinout (8 pin DIP) Figure below shows the ...

自 1972 年推出以来，555 定时器 IC一直在市场上广泛使用。在 IC 技术编年史中，那是恐龙时代。这种基本未改变的 IC 已经生产了很长时间，目前仍有十几家厂商提供这种芯片。我找不到具体的数字，但我怀疑每年仍有数百万人在使用传统和新设计。那么也许是 ...

Save guides, add subjects and pick up where you left off with your BBC account. The 555 timer is a versatile integrated circuit (IC) that can control timing in electronic circuits. It's one of the ...

[Kenneth Finnegan] took the focus of a great design and redirected it to solve his own problem. What results is this lead acid battery charger based on the 555 timer. It’s not a top-of-the-line, all ...

Hans Camenzind, the designer of the popular 555 timer IC died this week in Silicon Valley. He was 78. My condolences to his family and friends. Hans came to the U.S. from Switzerland in 1960. He ...
