We found this parking light circuit for automotive use in a Texas Instruments optoelectronics documentation. The Darlington transistor can be replaced by others in the TIP line.
This circuit is from a publication from the 50's. Inductive components are critical, and...
This simple two-transistor circuit used transistors from the 60s, having been found in a...
This circuit uses an oscillator that generates a signal of approximately 1450 kHz to test...
