This guy is making real things,and he even answers to questions to explain his projects.for that reason.I subscribe.

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.

All these fun little projects on youtube make me want to invest in some tools lots of tools

your presentation skills are getting better. nice little project.

That looks great! Excellent strobing effect! 🚨👍🏼

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.

Its fantastic! Many thanks!

If I gonna use this in a 2v led strip what value of capacitor and resistor will I use?

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?

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?

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

superb tutorial..thanks a lot.

Ideal para la moto y chau relé gracias por el vídeo.

Must be tray to make this ideas. Love it 👍 and Thank You 🙏

COOL . SIMPLE E MUITO BEM EXPLICADO E MONTADO . PARABÉNS . VALEU

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

Good content bro, love from kerala

Bloody fantastic thanks

good evening you liked the green led. great videos happy New Year

Great job brother. .

Wow , you are very generous giving us all those informations (meaning all your projects).For an 50 W (maximum) led outside projector with sensor, what modification should I do?Thanks.

Thanks! I subscribed

Perhaps we could skip making music videos and actually explain stuff by talking?

Oscilador por saturación a ruptura o vavalancha, ¿es cierto? Buen video, gracias.

Very simple and nice

hi. I need this strobe light but powered by a 2s lipo, 8,4 v fully charged. It will work? Thanks

Avalanche breakdown. Nice illustration.

A very nice work. I have a question! Can we burn more than one led diode with this circuit or a different circuit? Thanks.

Great, is it what I was looking for, how many LEDs can be connected to this system? How many volts does it work with?

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.

Awesome idea

saved it for watch later bro nice!

Can be use for RC PLANE nice 👍

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

Nice video! Can you explain how transistor switchs on and off without variation of potential on its gate?

Wonderful...Thank u...

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

Always connect the negative terminal from the supply first to the circuit :-)

Nice video, thanks :)

Muito bom! Very nice! Sp Brasil , obrigado. Thanks!

What if I want to have a super bright strobe? Can you do a video on that?

Can i use it for 9v ?. and im gonna add 3 LED's at the same time , it will work ?.

The ultimate transistor burning machine.

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.

Us Motorcycle guys need help with these. Can you use the clear LED and focus it with a lens so we can put this on the front of our bikes for visability.

How to increase / decrease the time between two flashes?

Nice!

' that nice idea... can do that work with 6 volts batterys... dont need 12 volts... what size of LED 3mm or 5mm... what BC547 to do with middle pin between C and E

perfect man

How many LEDs do you support?

Good job, any simple project for pulsing led ?, thx

What is the resistor values for Red, Yellow, Blue and White LED's?

Im using 12v led what is the resistor ohm should u use

Great

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.

Mantap kreatif

Hey, the music is repetitive and annoying. Every dam video has the same distraction. But good work 👍

Hi can you please help to make a Butter Churner using bidirectional motor?

fantastic

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?

Bought an airplane to take that transistor out and complete this video tutorial

அருமை....

how does it works? without triggering base?

thenks bro nice

how many leds can be used in this circuit?

Now i am going to make my own home made plane with strobe light😅

It would have been nice if you had explained why it works.

Nice job

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

hahaha great job😀

Thanks 🙏 for the reference

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..?🤔

What are the specs on the LED? 5V? 12V? How many mA?

12v light use kr skte hai....

It didn't work in tinkercad circuit design, can someone help? I'm new to Transistor circuits and I used a PNP transistor and copied the exact circuit. The LED anode is attached to the emitter of the transistor. Anyone have advice.

Nice video Make video with 5w led flasher with 12 v dc input

For 5 v supply resistance used?

Hocam bu devreye otomobildeki 12 volt bağlarsak olurmu veya sonuç ne olur

Wow esta genial maestro.!!

What are the materials? is it easy to do?

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

Can i use 12v led smd instead of single led 3v

very nice 👍👍👍👍

I like the old Method by using a Voltage Multiplier Circuit, then you can flash a LED even with a AA/AAA (rechargable) Battery

Did it work for 12volts led?

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

Nice video

how can I make one for 5 V input ?

just for one LED?

This will work perfectly on my Airplane ✈️ models. Can you please show me how to make the same thing but a double strobe ? Shown on the ends of the wings of a 747-8 Jumbo.

Good for bikes and scooters with 12v

4 led lagau to support kr jye gaa?

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 !!

Mạch chớp này rất hay

This led strobe can connect to bike?

Nice project

i try this Strobe after work today :-)

What changes need if we want to add 50 led

Can anyone here how the set up would look like if I wanted to use more LEDs, for example 5 or even 10 without having to make the whole thing over and over again. I want to make a warning light for a gate.
