@@SixOThree capacitor charges itself through battery, and transistor consumes capacitor's energy and convert the electrical signal to turn on the led, as much long power is hold by capacitor, led will be "On", once capacitor is fully discharged led turns "off" and capacitor charges itself again, and the cycle continous to infinity, that's what we call "blinking of led" the purpose of resistor is to glow led without burning it

Is it possible using three or two light?

This 'negative resistance' oscillator uses the transistor's emitter to base in breakdown mode, which is to be avoided because it degrades the transistor. This circuit is never used in any mass produced equipment because the transistors are not tested and were not designed to be used in breakdown mode. It must be avoided to prevent damage.

@Acme Fixer: I don't think so. Assuming the LED chokes 2V, then breakdown voltage of the transistor is max 10V, so max current thru C-E is 70mA (limited by 150R resistor), not enough to kill the transistor.

03:05 I would suggest a 1N4007 in series with the 3K3 Ohm resistor sothat )I electrolytic capacitors could be safety used.

your presentation skills are getting better. nice little project.

Let me try to explain how it works. By RC = t, 3.3k resistor and 100u cap forms a time constant around 0.33s. When the cap just be charged, voltage of cap is lower than the acceptable reverse voltage of the VCE of the transistor. CE of transistor keeps open circuit then LED is off. However, once the cap voltage reaches over VCE, transistor becomes short circuit. It turns on the LED and also discharge the cap at the same time to complete one cycle operation. However, this circuit just works in high power supply voltage and the transistor may be damaged after a long time operation. To make this circuit more reliable, the transistor can be replaced by a zener diode, then using a NPN transistor which drives from the net between zener and LED to discharge the cap.

I agree with the zener diode. the transistor isn't doing much other than acting like a diode. base isn't being used switch it on/off.

I love the ideas and I really like it! Simpoe and easy! Thank you. But, is there a way to power on in 3v-3.7v battery? What changes will be needed?

Bloody fantastic thanks

Someone has probably already answered this I'm sure, but isn't this avalanche pulse generation? The transistor rapidly conducts current when the voltage across the capacitor reaches the collector-emitter avalanche voltage. I thought the capacitor in an avalanche pulse generator had to be small to keep the energy from causing the PN junction to fail? Does this having the emitter connected to the positive plate, instead of the collector, have something to do with keeping that from happening?

Thank you so much, it's thanks to you that I did what I wanted

Changing the value of the capacitor alters the time constant increasing or decreasing the rate of flash.

What does a resistor doing in the circuit ? I know it resist the current. But how is it helping the circuit ? i really wanna know

Collector is on the right side and emitter is on the left side; I think you need to switch the C and the E on the video. I never knew a transistor allows current to flow without any current to flow through the base.

That's a nice simple timer circuit. Let's see it on a little circuit board instead of this "mid-air" style of construction. It's kind of cute, but if I'm mounting three of these to my RC plane, I'm looking for stable mounting, not a floppy gob of parts. Or do you pot it in RTV for rigidity?

Working fine... someone please explain why the base terminal is not connected to the external circuit.

I had already contructed the circuit with VRs too instead of Resistors to observe the blinking effect and is working fine but very strange fact I could notice but couldn't find the exact logical reason behind the issue. When I use ordinary BC547 the circuit works fine but I used the same transistor from leading manufacturers the circuit even didn't start and each and everytime same result obtained. Can anybody let me know the reason??? Thanks in advance.

@@joeycarr1398 The circuit here only works with battery voltage above the transistors reverse breakdown voltage, which is something like 5V. (Note that the transistor is connected in reverse polarity on purpose for the circuit to work) Also the timing is highly dependant on the supply voltage. Thats why sawajiri100 suggest a different resistor value of 2.2K to still have a decent blink rate on a 2S battery. A 1S battery in the RC hobby world is one 3.7V cell LiOn battery, hence a 2S battery is 7.4V.

No work is small. Happiness is similar if we succeed in making small projects or big rocket.

Hola, ¿ Se puede hacer con una fuente de 5 voltios?, ¿que resistencias necesitaría?

What are the materials? is it easy to do?

If that cell is a Li Ion cell, it needs to have a bms chip to avoid excessive discharge which would risk explosion or fire. They can be had even for a single cell, and are very cheap. A couple of dollar "insurance policy" can avoid those risks.

actually the circuit abuses the negative resistance factor in all transistor to produce the blinking effect. Here a common NPN transistor is used. When Switched On the 3.3K resistor charges the 100uf capacitor until the voltage become high enough to get emitter-base junction to avalanche. At this moment the transistor turned on quickly and the capacitor discharged by led through 150ohm resistor, and when voltage across the leads fall, the current stops, then the capacitor again starts to charge through 3.3k resistor. Thank you

Yo nunca lo he implementado así que no sé cuanto tiempo podría funcionar. Los fabricantes no dan información acerca de este modo en las hojas de características. Yo creo que no es perjudicial a estos niveles y se puede hacer un cálculo térmico sencillo. Que yo sepa la conducción por avalancha no es destructiva si se limita la potencia. En este caso es fácil ver que la potencia es muy inferior a 40mW (suposición de que la tensión y la corriente fuesen máximas todo el tiempo lo cual no es cierto ya que son pulsos muy estrechos; parece que brilla más tiempo del real por el tiempo de respuesta de nuestro sistema visual). Estes transistores soportan muy holgadamente esa potencia. Si bien los picos podrían ser destructivos incluso sin aumento de temperatura, estos picos son de solo unos 4 mA. Por otra parte, he visto videos con niveles de tensión en torno a 100V con otros transistores claro, puedes invesigar...

I think that 12V supply charging the 16V capacitor and when it discharge the bulb is blinking. but durring charging there's no current flow through bulb because of resisters.
