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.

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.

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