1.5 volt led flasher,that mean the led will work and flash with single
1.5 volt battery and to make this possible you need to build small skeleton circuit with 2 transistors.
1.5v led flasher,With one AA battery will blink 1 year
one question for u - why you make such videos, when u don't provide proper schematic diagram for making this projects, im asking you this question bcoz i had already disliked the video.
@@Rachitkivines Listen carefully to the audio - freeze frame if necessary and learn to draw schematics as shown - will be most helpful in building your own knowledge and experience. Cheers.
@@MichiganPeatMoss why make so much effort, when he can show the schematic on the full screen without any problem, it will be better to everyone to understand easily, not everyone is that brilliant to understand such complex circuits.
Works great. Thanks! I watched this so many times, I have developed a Russian accent!
Your schematic is wrong. You show +1.5v and -1.5volt. That is 3 volts. You need to show +1.5volt and 0 volt connection.
Oh god ! U waited 1 year to make this video 😂😂😂
All you folks that says is a really great circuit, what do you intend to use it for? I have a black cat with a black mat that I stand on when I do work in the kitchen, and I'm going to put around my kitty's neck using 1.5 v hearing aid batteries. I'll make a little collar for him.
Next I'm thinking of making him a device that When he lays down behind me when I'm doing dishes, it'll beep so I don't step on him.
1.5v hearing aid abttery has a lot smaller capacity. For me it worked only 4 days- after that light became dimmer . Turns out it has only 26mah, while ordinary 1.5v battery has about 1000-1600
Put it on a helium balloon and send it up. New UFO 😀
One of the first video I watch in TH-cam ,Amazing
scheme is not pretty clear to understand, and hard to see where you solder LED contacts, but thanks a lot for a cool circuit working with battery! (most vids on youtube is flashers working with 12V dc power supply)
-LED
-100k Ω
-2 x 1k Ω
-22 Ω
-10μF, 470μF, 10 nanoF
-npn transistor 2N3904
-pnp transistor 2N3906
-AA battery (working with accumulator 250mAh 3.7v as well )
BOOM done! Thanks!
Exactly what I was looking for, cheers.
Wow! I must make some of these! 😁👍
in schematic you used 22ohm resistor but verbaly 47 ohm registor.
Hi. I have made the circuit also but is flashing very fast. I have changed everything but cannot reduce flash rate. I put also a comment to this video with detailed description. Can you advise me if you know ? Thanks
Change your capacitor to get your desire flashing speed
I love this gadjick 😍😍😍😍
wow charming art thanks
I made one that flashed a white led for 2.5+ years on a single AA Battery and only one transistor.
Please can you post the Schematic. It's not clear in the video.
Because he's a troll.
How is it 1y when base current is 6mA
hi can i ask you a question ? if you have time ?
Please make a 3.5 volt plane light at home
What's with the spasticated diagram
At least he has a diagram.
Very good 👍
He is not showing the video in a straightforward way with necessary circuit diagram and components.He is showing his lab set-up unnecessarily.It not needed.
This works, I have built the circuit. But I don't know if it will last a year?
Did it last few months ? How is it 1y when base current is 6mA
Wow for 3 years. ...nice
*Nice video*
I looking for a blinker but only I can see are flashers.
At 2:41 you used a blue led but then used a green one at 2:44. Why?
my experience: this circuit works only for 6 month
Still a long time
I love this!
Bro can you make 5 led with speed controller blinker. Thank you
Nice one
great video but i need one for a 5v rc receiver cxan you plz make one for us RC PLANE ppl
I solder it same as you but it’s not work😓 what is the voltage of your LEDs ?
Can i ask you some questions about this
Its not complicated as it looks
Can I use bc547 and bc557 transistor ?
My cricuit work with 4v what can i do ?
Can u make more simple circuit using 3.7V battery and blinking delay of 5sec, which works for 1year? Plzzz🙏
I will try it
@@Hacktuber well if u add ldr in circuit then it will last for 2 yrs!!!😀
please explain patiently
Try with joule thief flasher ONLY ONE TRANSISTOR
But you need to do a coil with a lot of spins.
Sir please give me one flaser.
plz bro send its circuit diagram
O Some project ☺☺
Nice brother
Thanks for sharing
No problem
That's another thing you showed the scheme
Hi. I need your help regarding the flash rate of the circuit. I have made it with a clear red led and it is flashing very fast 1flash/1.5-2 seconds. I have changed the 100uF capacitor to 330uF; 470uF; 1000uF; 2200uF but the flashing rate remain the same = very fast. After that I changed the transistors and in the RC oscilator the 10nF capacitor + 1K resistor values several time with other values, but no good result. Where can be the problem ? How can be reduced the flashing rate ? For example 1flash/5sec . Thanks. ( PS : The Joule thief version of 1.5V led flasher is very simple and you can change the flash rate only changing the big capacitor. )
@Jack Luck Thanks for feedback. I have changed everything also the 47 ohm resistor ( 22 ohm on his paper ) but cannot control de flash rate. It is very fast to have 1flash/ 1.5seconds. This circuit has no tolerances to play with flash rate. I have made also the other type of 1.5v led flasher : Joule thief + one BC 547 transistor and it is working very nice. Simple circuit and you can control the time between the flashing only changing the big capacitor.
@Jack Luck I think that is the only way to change the flash rate : change the load. If you will use only 1 pcs of 5mm led the flash rate is very fast. This is too fast for me. I have good results with Joule thief version. On You tube is a guy who made it to work 4 years with one 1.5V battery.
@Jack Luck th-cam.com/video/_t6qip8HKyw/w-d-xo.html
change 10uf cap to 20uf or 30uf for slower flashing rate
please make led blink 10 years circuit
You will need very power efficient LEDs and transistors.
@@ElectroGuruji this is the circuit I am curious to see it inside the resin
seems to be the same common led th-cam.com/video/DOajZVz8n6o/w-d-xo.html
Use D battery, will blink 10 years
Mantap dan keren 😎😎😎😎😎😎
This part very nice #;)
cool

First yo Indian
Can we use 555 timer?
555 Timers run in the 5 volt range.
Self blinking LEDs already available. 😐 But if you want to test different capacitors, build this circuit. Otherwise, buy self blinking LEDs... 😐
Yeeeee, this is big brain time
That's true, but the forward voltage of LEDs is too high for a single 1.5V battery. This circuit also acts as a small boost converter by charging and then switching the two caps in series to achieve the higher voltage.

Please reply me
He wont
Yes as soon as i find use for this crap i'll make one. :-)
Why are you even here? Wasting time watching the video then taking the time to comment on how you wasted your time.
Update on these?
