Is that the giant NE555V? Super chip even to this day!

I met Hans Camenzind (designer of the 555 under contract to Signetics) in the 70s when the company I worked for used some semi-custom ICs from his company (Interdesign). The 555 was incredibly popular .

It is. Well spotted.

Many years ago when I studied electronics in college our first project was a 555 based circuit which we had to design and etch a pcb for , I technically failed it because I shrunk the pcb down to the size of a small postage stamp , it was still the neatest job in the class by far . In some ways I kinda wish now I'd continued and gone on to technical college or university , still time I suppose . I do like the unstructured learning here , Id say its hard to find even colleges with the combined audio knowledge off all the contributors here .

Finally, a 555 that doesn't require an external driver transistor for high current loads! Looks like it might work well for pulsed current TIG welding.

You could wire it into the room to turn the lights on after your 'thinking time' is up.

I would instantly buy one without hesitation.
