@labria Interesting. I am preparing an order at Digikey to replenish my parts stock and had a look on my 555. Only two left and I can't remember when I bought it. Could be 20 years ago, maybe longer. I can't remember when I used one last time in a project...

It's somehow sad because it is such a monument of IC history and it's great to hear it's not obsolete.

People, use more 555!

New video (also the final one for this year)! I found a strange Hi-Fi component on the side of the road and am taking a closer look at it.

Built my first little 555 astable timer today ⏱️⚡
Just a humble LED blinker, but it feels like magic when the circuit comes alive.
Maybe this is the start of my journey into electronics and 8-bit retro computing.
