Interesting.....I just tried this with a 2N3904 small signal transistor, a 220 uF capacitor and a 4.7K resistor, and it worked perfectly. My pulse interval is about the same as this video, but the flash duration seems shorter.(almost like a strobe) I never guessed, that a transistor would act like a relaxation oscillator, when current is applied in the reverse polarity across its emitter-collector junction. The capacitor varies between about 1.8 to 2 volts, the transistor drops about 3 volts from the time it reaches reverse breakdown voltage, to where it turns off again. You indeed need a 12 volt supply, to get to the avalanche voltage of the transistor. Much below that, the transistor won't reach the voltage necessary, to go into conduction. The base has to float. connecting the base to the emitter just turns the transistor on and leaves it on, connecting it to the collector never allows the transistor to enter into hysteresis. it just acts like a Zener diode. The base is very susceptible to outside interference. I recommend cutting the base lead off as close to the transistor body as possible, unless you want to use the transistor in another experiment.

"Thank GOD"🙏🏾, and thank you very much for sharing your support and time 😉 I see ALL the LEDs are flashing at the same rate 🙄 with the same amount of brightness 😁 Well done 👍🏿

No se si probaste el circuito, pero el esquema del vídeo no va a funcionar si no se alimenta la base del transistor para que circule corriente entre colector y emisor. La manera de mostrar en el vídeo de que los leds parpadean es porque debe de estar utilizando como fuente de alimentación un generador de frecuencia y es así como consigue la intermitencia de dichos leds.

This is exactly what I was looking for. I wanted to simulate the flashing in a salvaged End of Train Device (ETD) for a museum I volunteer at. The 1k resistor limits the input current to 12 mA for a 12 V battery. At that rate, it could run over a month on a 10 aH gel battery. Perfect!

The original flasher board was removed and I replaced it with a breadboard that has eight LEDs in parallel. Of course it's not as bright as the original. But it's bright enough to get people's attention and help tell the story.

For 9V battery should be reduced the resistor value or not ? Because light intensity is not so high like at 12V !

Your transistor is dead -thats why it works..For this circuit you dont need the transistor-It works without it-With working transistor it can NEVER work!

@pbs1516

4 жыл бұрын

You're wrong. The transistor is not dead and without it, the circuit wouldn't work : the LED would just glow constantly, the current being limited by the 1k resistor. It is a very unusual way to use a bipolar transistor, also because collector and emitter are reversed (which is done on purpose). I can give you more explaination if you want. However, the fact that it works doesn't mean that it's a good idea : it is in fact a very bad idea. Nothing limits the current excepted the LED dynamic resistance, the transistor one, and the capacitor equivalent series resistance. So you have a large current spike, which is very stressful for the transistor in this condition (as it has like 6-8V between its terminals, a few amps means a peak power of 10s of W!) And also for the LED, by the way...

Jule Rulez Hi! I insist : it works (I even built the circuit to be sure), and with a perfectly working transistor! I would be pleased to discuss that with you. If you're like me, you noticed two unusual things in this schematic : first the base is left open, and then, the collector and emitter pins seems reversed (as in this circuit, Vce will always be negative). We will come to the second point later, which will not change the operation principle, but only the numerical values. So just imagine that you have the same circuit, but with the emitter connected to the LED and the collector connected to the capacitor "+" terminal. A NPN transistor is basically composed of two (coupled) diodes, with their anodes tied together at the base (B), and their cathodes going on the collector (C) and the emitter (E). In that case, the base-emitter junction (BE) is forward-biased and will not stop current flow as long as the voltage is greated than ~0.7V. The BC junction, however, is reverse biased. If the CE voltage is low enough, no current will flow : this is the "normal operation" of the NPN transistor at Ib=0. But if you increase the voltage high enough, the BC junction will exhibit avalanche : a possibly high current will start to flow, exactly as in a Zener diode when you exceed the threshold voltage. If the BC and BE diodes were independant, the device in this mode would only clamp the CE voltage to Vavalanche + Vbesat (approx Vavalanche itself). Like a Zener diode, again. But the're on the same die! When the avalanche current starts to flow, it will significantly modify the behavior of the BE junction (already conducting, thanks to the leakage current of the BC junction before avalanche), and the global CE voltage will exhibit a steep and sudden decrease. The current increases while voltage decreases : this is a negative dynamic resistance behavior, needed in a circuit like this to obtain relaxation oscillations. When the current goes back to zero (because of the partial capacitor discharge), the avalanche stops. This phenomenon, with the voltage foldback (on threshold greater than off threshold) is sometimes referred as "open-base avalanche". In fact, in that case, the transistor works as a (bad and non-symmetric) DIAC! A simple DIAC has a three-layer, two-junction structure (for example NPN), like a bipolar transistor with open base. You can see it hidden in the datasheets, as you have generally two (or more) maximal "CE" voltages : Vceo (between C and E, open base) and Vcbo (between C and B, open emitter). They should be the same as BE is always forward biased (~0.7V)... But Vceo
