LED Watch Chip Goodness
🕑 Added 2020-09-27 08:31:42 +0000 UTCRemember that Chinese sourced TI clock chip that we decapped with Antoine? Not fake at all tells me Ken Shirriff. But does it actually work? It sure did not when I put it on my HP board. One simple way to find out. Chinese sourced TI chip, 1970's HP bubble LED, proto board, and a bit of fun reverse engineering as this chip is completely undocumented. 2.5V power, kooooontakt! Result is beautifully vintage! Video should be out soon.

I remember when Radio Shack sold the assortment packs of components and it was not uncommon for those bubble LEDs to be included.
