An LED as a light Sensor

How's that for dating myself!!!!!

Doesn't "dating oneself" lead to hairy palms?

Aparently so Joval, as far back as 1978 it says in the pdf i read, and their only just telling us now? BTW i hear Veet works well on them Palms, lol

Don't worry about dating yourself?... Remember the OC71 germanium transistor and the OCP71 photo transistor. They were the same device but the OC71 was covered in black paint and cost 10 times less than the OCP71 so we used to scrape the paint off! The manufacturers retaliated by filling the OC71 with opaque paste. We got around this by attatching the transistor by its legs into a spin dryer and driving the paste down away from the junction. Those were the days! John, PIC newby.

All,
Thanks for the comments!!! YOUNG WHIPERSNAPPERS!!!!
Yea, those were the days before the 2N nomenclature. Remember well the OCs and the transistor gain testers.

Everything else but lamps, HeathKit kits, first analog VOM... that's were the days


Argghhh we're all old now

Yes, I still have my Heathkit OS-1 oscilloscope. It was built and owned by the late ill fated Don Crowhurst around 1964. I marvel at these modern PICs, they would have made our lives so much easier :-)
