Flasher and Blinkers Light Flashing Circuits Electronics ...
Flasher and Blinkers Light Flashing Circuits and Tutorials This circuit is similar to the LED clock using12 neon indicator lamps instead of LEDs. It operates from2 high capacity ni cad cells (2.5 volts) which keep it going for a couple weeks.High power LED flashlight circuit with 1.5V AA battery
This high power LED flashlight circuit look like a torch by use on 1.5V battery only so it can be used. Since small so Easy to carry in various places. And also very bright as well. The technical information. Power supply : one 1.5V AA battery. Maximum current used 200mATransistor 101science
2. TYPICAL TRANSISTOR CIRCUIT This is a silicon transistor circuit showing typical voltage values.When the forward base emitter voltage is 0.6 to 0.7 V, the transistor is silicon. Germanium transistors will have a forward base emitter bias voltage of 0.2 to 0.3 V This is a silicon transistor because 2.6 base volts minus 1.9 emitter volts equal a forward bias of 0.7 volts indicating a silicon ...How to Build a Simple LED Driver Circuit
This circuit exploits the fact that transistors can function as current amplifiers in circuits. We use the transistor to supply the amplification necessary so that the LED can be driven.Sensitive Sound Activated LED | Circuit Diagram
The operating voltage of the circuit is 12 volt DC but you can also operate it with 9 volts. If you want to operate the circuit with 9 volts remove one LED from the 3 LEDs in each line and use 180 ohms resistor in the place of 68 ohms as shown in figure 2.LED flashers, Line powered LEDs, LED Traffic lights
Line Powered White LEDs The LED circuit below is an example of using 25 white LEDs in series connected to the 120VAC line. It can be modified for more or less LEDs by adjusting the resistor value.PINBALL: Repair Bally 6803 Pinball Games 1985 1989.
A concept that never really worked well, but that Bally obviously thought was a great idea, was the keypad input. Inside every 6803 game (except Escape from Lost World, Blackwater 100, Truckstop and Atlantis), there was a keypad with the numbers 0 to 9, A to F, and "enter", "keybd clr", and "game" buttoms.Microcontrollers, Analog, RF, and all three mixed. Cappels
Most projects can be assembled from readily available parts without the need for specialized equipment. My hope is that you will find these projects helpful, and at least be able to make use of some of the bits and pieces you will find among themTransmitter Circuits Electronics Tutorial and Schematics ...
