I still have the Forrest Mims III Radio Shack "555 Engineer's Mini-Notebook" somewhere in my basement. And rumor has it that Sammy Hagar can't drive 555 because his car just isn't fast enough!

5:55 video released on May 5th, as per description :)

For something feeling like a fairly specific IC, I remember seeing many projects that use it throughout the years in wacky ways - and seeing it makes me happy to know that the sentiment for this little piece is shared.

Built an atari punk console using these with my late father. Still have it hanging on my wall in a shadow box.

I recently dug one out to use as a hardware shutdown timer to power off an rpi's PSU once it has presumably halted without having to resort to a dedicated MCU for the task.

Oh god I feel old. I remember being an excited schoolboy thinking how magic this was when it debuted.

I also remember being amazed, and did a forehead slap, when an old army bomb disposal man explained how, what I thought was an innocent device, was used by the IRA in bombs.

Ha. When I was a teenager I used to build 555s into timers for the same purpose using a no PCB rats nest construction.

Though surprising the family at dinner with a small explosion was a much more innocent purpose.
