In the upcoming Open Circuits from No Starch Press, authors Windell Oskay, co-founder of Evil Mad Scientist Laboratories, and ... Take the humble LED filament light bulb, ...

The “two flashing led” circuit is designed for 9 Volts but it works at lower voltages too. In this design we used red leds but by changing the series resistors R1 and R4 you can also use different LED ...

The resistance between B1 and B2, when the emitter is open-circuit is called inter-base resistance. The 2N2646 is the most commonly used version of the ... The discharge of C2 is followed by its ...

LED driver outputs may also be damaged or destroyed by short circuits. Most LED drivers include built-in safety features, including thermal shutdown, as well as open and short LED detection. However, ...

For a 45-meter RG-58/U cable, the LED will flash at f1 = 1.67 Hz. When an open circuit is introduced at L2 = 25 meters from the IC, the LED will blink at about f2 = 3 Hz.

In production, this may be replaced with a zero Ohm resistor. The open circuit protection circuit shown utilizes R9, causing it to serve an additional function, in conjunction with Zener diode D2. In ...

LED Circuit Diagram – LED strobe has independent delay and duration High-brightness LEDs, with independent delay and duration, find use in a visual-inspection application. This circuit is not complex, ...
