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.

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.
@acmefixer15 жыл бұрын
@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.

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?

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

@@JamilKhan-hk1wl Not necessarily. Even a 5V supply is enough to burn your components and damage your board.
@@imtheroboart not if there is current limiting resistors
Jamil Khan Wait, you’ve never seen a resistor flash-fry? 🤨
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.
Not on a BC547, it's opposite of a 2N2222 from what I've seen online.
Wow esta genial maestro.!!
Nice video
I tried this circuit on bread board. Didn't work. Checked connections again and again. What could be the problem? FYI i am applying 9 V instead of 12 as mentioned in the diagram / video
how does it works? without triggering base?
How to increase / decrease the time between two flashes?
4 led lagau to support kr jye gaa?
No work is small. Happiness is similar if we succeed in making small projects or big rocket.
Any problem of changing Supply volt... Can use 3.7v, 7v, 9v, is it work correctly...? Plzzz rplyy
12v led use kr skte hai....
How many LEDs do you support?
Bought an airplane to take that transistor out and complete this video tutorial
Bohat aala
I have all the parts and hooked up. No strobe effect. Followed instructions as indicated on your KZhead video. Please advice as to what I'm doing wrong. Very much like to have a few of these to light up my model StarTrek Starships. Thanks for your time, Jim.
Ok, you've done alright, now just increase the input voltage to about 13.5 to 14 volt.
I figured another way. Put the 150 ohm in place of the 3.3k. Then removed the 150 ohm and put a 75k in it's place to run off of 12v.
Im using 12v led what is the resistor ohm should u use
I like the old Method by using a Voltage Multiplier Circuit, then you can flash a LED even with a AA/AAA (rechargable) Battery
Can u give the link for that video
Wow
Now i am going to make my own home made plane with strobe light😅
Thanks for the Video. I wonder how the circuit works when no power is on the Base of the transistor,so the citcuit between C and E is open permanently.. can you help me understand? Greetings
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
@@TechIdeasAG Thank you very much:-) that helped me :-)
Hocam bu devreye otomobildeki 12 volt bağlarsak olurmu veya sonuç ne olur
Thank you for the video. I am nubie in electronics, I tried and did like what you showed, but it worked only if I touch the led's plus pin with one of the multimeter needle. May I ask what seem to be the problem?
Check the soldering if you do not have much experience in soldering .Erratic behaviour of the circuit is possible in case of wrong or loose connection.
@@chetananam475 ok. Will try again from start. Thank you.
Total cost kitni padegi bro if i use 3 watt led bulb
As a gift to all Amateur and Professional Electronics artisans, working boardless has advantages. Minimalist designs are beautiful. I wonder only why force 12V on us ?? 6V or less won't work ?? A pair of Crafters wire bending pliers might be a GODsend. Two pair even better.... one smaller, one larger ?? Another tip ... the Weller pen version of soldering iron works nicely with EXACTO BLADES.... cutting shapes and openings in plastics, shall never be gory. Be Careful... Cuts and Cauterizes too !!
Superb!👍
My led bulb is so fast blinking
Increase the capacitor value
Kya ispe 2 led chalegi ek saath ??
Hey how can I blink my 220f tail lamp like the same way, can I use the same circuit directly to a12 volt dc battery of my bike..?🤔
Use realy
I really like your ideas. How to do a circuit like this with 15 reds LED and 12v supply? Thanks
Not possible
Would your circuit work with a super bright white LED? I want something that can be seen in sunlight to light up a drone in the sky. Is it do-able? Thanks.
Nope, it will not work in your condition
@@TechIdeasAG Thanks.
Hi can you please help to make a Butter Churner using bidirectional motor?
how many leds can be used in this circuit?
