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.Transistor 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 ...70 Interesting Circuits Talking Electronics
12v LAMP DIMMER Here is a 12 volt @ 2 amp lamp dimmer that can be used to dim a standard 25 watt bulb by controlling the duty cycle of a astable 555 timer oscillator.1 200 Transistor Circuits Talking Electronics
INTRODUCTION This e book contains 100 transistor circuits. The second part of this e book will contain a further 100 circuits. Most of them can be made with components from your "junk box" and hopefully you can put them together in less than an hour.Power Control techlib
Basic Lamp Dimmer. Lamp dimmers using traics can be quite simple, nothing more than a potentiometer, resistor, capacitor and triac with a built in diac.LED (Light Emitting Diodes) Circuits Electronics ...
LED (Light Emitting Diodes) Circuits and Tutorials 1.5v LED FLASHER: This is a very basic little circuit built around the LM3909 IC. A list of components and values is included.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.Ion Chambers techlib
Introduction These "ion chambers" are nothing more than a bare wire stuck through a hole into a metal can! No special gas or sealing is required.LED flashers, Line powered LEDs, LED Traffic lights
AC Line powered LEDs The circuit below illustrates powering a LED (or two) from the 120 volt AC line using a capacitor to drop the voltage and a small resistor to limit the inrush current.Bowden's Hobby Circuits
owden's Hobby Circuits. A small collection of electronic circuits for the hobbyist or student. Site includes 100 circuit diagrams with text descriptions, several electronic calculators, links to related sites, commercial kits and projects, newsgroups, and educational areas.
