Blinking LEDs!

[ezdays]

Blinking LED's are not that new. I had bought a batch of them a good 15 years ago along with some other surplus parts. I seem to remember though, that they were the larger, T1 3/4 size. I didn't have a use for them, so I sold them to an electronic dealer at a slight profit. They apparently sold well since he called me later on and wanted to buy more. And yes, they do have a flashing circuit in them an so they do require a constant voltage source like most any circuit.
