Category: Inside Circuits Views: 5286 Rank: 10 That Circuit is an advanced bicycle lighting system which will power your lights and also charge four NiCd batteries while you running in the streets, for keeping the lights on while the bicycle is stoped. Its fully automated without any switches.  You can not even use any PCB for that circuit. Datasheet file1: Click here to download BUZ10A.pdf datasheet.

Related circuits Lamp II is a household lamp. When the switch is in the center position, the lamp is operated on half-wave rectified ac; the ef A relay and two diodes are all tliat is needed the relay performs the job of a buzzer so no annunciator is required. When the lights are left on, but the ignition is off, the normally closcd relay contacts are in series with the relay coil. That means the relay interrupts its own power each time... Using an NEC70083, this 1296-MHz amplifier delivers about 17-dB gain and around 1- to 1.5-dB noise. It is constructed This circuit is useful if you need a low-energy flashing alarm. The 200 to 400-dc supply should have enough internal resistance to charge the 0.5 capacitor between flashes, about 2 or 3 time constants, which means about 500 kQ to 1 for a 1-s rate. This circuit will enable a CMOS logic chip, such as a 4017 decode driver, to control a string of Christmas lights or Simple Field Strength Meter Ii Circuit This simple field-strength meter provides a cheap way to monitor an amateur radio or CD transmitter (or even an antenna system) Quality FM-TV micro transmitter 40-200 Mhz This Transmitter can be powered by a battery 9V (not more than 12V). You can connect your music source where the microphone is or use a simple condenser microphone. The range of signal can reach 400 meters in open air. The wide range of frequency is up to you. Tune it at FM band (88-108) or TV... Using an Intersil ICL8038, this function generator generates frequencies from 1 Hz to over 80 kHz.
