Transistors Qi Since the 270 ps capacitor is charged at this time, it forces the pin 1 terminal below the supply common value; consequently, the LED volt drop is greater than the supply voltage value! Practical LM3909 circuits Figure 2.18 shows the Figure 2.17 1 V5 flasher circuit redrawn in a practical configuration.Each circuit is built around the same integrated circuit operating as an astable multivibrator, or clock. Six different projects are created with only slight changes in circuit design. Furthermore, even if the project isn't altered at all, its function can be.changed simply by redefining what the project is. For example, in Figure 1.15a, is the circuit an LED blinker? A modelrailroad crossing indicator? An emergency flasher for joggers? An attention getter to place on your cap? A tester for 555 ICs?Though LEDs (lightemitting diodes) are commonly used as everything from panel indicator lamps to the tiny flashers on sun visors, many technicians continue to find them somewhat mysterious. This article describing two simple LED circuits should remove some of The flashing—LED circuit depicted in Figure 3 might be used to indicate the location of offstage emergency equipment such as fire extinguishers and first aid kits.

RETAIL $104.95 PART # 20500027 DUAL LOAD Suppose you are in a building and suddenly you are plunged into darkness as a result of power loss through fire or accident; how do you go about locating emergency exits or switches or fire extinguishers, etc? The obvious answer is to fit each of these points with its own permanently operating and ultrareliable.batterypowered flashing LED 'beacon' unit. To be commercially viable the unit must be very cheap, be able to operate from a standard 1.5V battery even when it is near the PROJECT OF THE MONTH BY FORREST M. MIMS Many highbrilliance lightflasher circuits have been published over the years in this and other electronics magazines. Almost every one of these flashers has employed power transistors or SCRs, components which require heat sinking and careful circuit design. Figure 1 shows an ultrasimple flasher circuit that 1 recently built around an FRL4403 flashing LED, with only a few additional components. It will flash at a typical rate of 3 196 latch/decoder/driver, BCDto7seg ment display, 135 LED, 163 pulsed relay,.330 relay driver oscillator, 357 relay driver oscillator, variable frequency, 357 TTL, 173, 173, 414 TTLgate, 165, 165 voltage comparator, DTL or TTL driver, 243 voltage comparator, RTL or high current driver, 242 DS1386/DS1486 watchdog Timekeeper, 142, 142 DS1620 digital thermometer/thermostat, 144, 144 E electronic shutdown circuit, 387 emergency lantern/flasher, 358 ExclusiveNOR gate, Defroster operative when conditions require it.
