Reply to comment by AnthillOmbudsman in TIL in 1962 a General Electric engineer named Nick Holonyak developed the first LED light bulb capable of emitting visible red light. The same bulb was used in the 1964 stop animation animated TV special Rudolph the Red-Nosed Reindeer for Rudolph’s bioluminescent nose. by undergroundgeek

I think early LEDs were more commonly used as point illumination.

I have a 1978-model reciever that uses red LEDs for input indicators, but bulbs for lighting the meters and dial scale.

Reply to TIL that in an effort to save $43.5, the Canadian Mint mailed the dies of the new $1 coin via a discount courier over using an armored car- which were promptly stolen and have never been found. This would lead to the adoption of the Loonie design as an emergency replacement. by Padgriffin

I had heard it was deliberate. The plan was to use the Loon design all along, but there was public outcry to continue the Voyageur design from the old nickel and silver dollar back to 1935.

"Losing" the dies allows them to present it in a face-saving way. They really wanted to use the other design, honest for reals, but it got lost in shipment. Anyway...
