Hello, as the video is two years old I hope you'll see my question: I do a lot of recovery to avoid buying components that can still be used, however I have no idea where, or rather in what type of device, I can find these transistor npn bc547, could you tell me when devices doomed to destruction / waste I can find please, as it would be to try I do not want to buy a bag of several of these transitors. I also see that you use this other component (220 muh inductor) for this type of manufacture. Can we find any in devices and if so, in which ones (always with the idea of reusing components that would be destroyed if not recovered) and don't LEDs need a resistor in this type of assembly? Thanks in advance
You can use any type of components from anywhere. Yes the BC547 can be used. 220muh inductor maybe you can find from computer Power supply boards.
@EDISON_SCIENCE_CORNER thank you for taking the time to reply and thank you for the information. ;o)
Good idea
Yes
Superb keep rocking 👍
Thanks broo
Does it have to be round charging outer shape.?
No
@EDISON_SCIENCE_CORNER Thank you, I wanted to make a product that needs a rectangle & I can make the corners soft bend & not a hard 90 squared edge / corners. Please have a great rest of your day...
Would you be willing to make a video showing different shapes that work but to address things like, how hard the corners can be before the current flow is decreased or in danger of creating hot spots that may cause fire or damage to items when used in inventions. Would love to see that & i think others may to if your willing to & can afford to create that. Alot of use can't afford R&D & by you making content, you get the on going youtube revenue, supporters, likes & we get to know valuable research and development info while watching another awesome video. If not,, it's cool, i can ask another youtube channel.. @EDISON_SCIENCE_CORNER
@@freespacejunkremoval you can make it rectangular but reduce the centre diameter or else the power will be too low
But can you boost the range of the leds
What range
I just randomly found you over instagram, i always wondered if i could make my own wireless Led with some small inductors, thanks for showing me its possible! Great Video!
Only one question: how did you change the circuit in the end for brighter glowing leds?
Thanks. I didn't changed the circuit i just decrese the size of the big coil.
If i want to increase the distance between the coil and the led, what should i do? Increase number of turns or increase the diameter of the coil?
Increase the number of turns, decrease the diameter ❣️
@@EDISON_SCIENCE_CORNER ok. I will give it a try
Increase the flux mind you your radial range will also decrease as you decrease the diameter meaning the LED will have less horizontal distance above the coil.
You attached the led straight on to the inductor? No need for capacitors?
No not necessarily
Good
😍
This is amazing instruction that I can actually use for my project! Thank you so much brother.
Ps, I will place the metallic material which has 2.5mm thickness, between the battery coil and transmitter. Will it would be still works in that condition?
I have no idea about that . We have to check that
can you tell me this transistor model name
Bc547
Hello! Amazing work!! I want to try this myself for gunpla. Can I use a bigger capacity battery like a 18650 lithium battery 3.7v. If so, would I need to change some components? like the resistor?
You can use but you have to change the resistor
Super sir
💖
Thank you very much, this was so helpful! ❤
👍😊
whats the resistor for? it only overheats for me
To limit current
Did you took inductor from 9w led smps? I tried the with inductor of led bulb but its power is too low but work well ! And instead of joule thief can we use 555 ic to power the coil?
No I bought new inductor. Yes you can try with 555 circuit
@@EDISON_SCIENCE_CORNER online or offline and where I can buy inductor cores in offline market
@@EDISON_SCIENCE_CORNER thanks
the circuit for the oscillator looks oddly familiar... oh! it's an adaptation of the classic joule thief.
Yes that's correct
I've never thought to try it for this. although i've used a toroid with an extra winding to make 100ish volts to run a neon from a single AA. @@EDISON_SCIENCE_CORNER
Does the led light up if you hold it near a 230v electric power cord?
No bro
Awesome! Greetings from Mexico.
Thank you from india
Also do you have an example for 12V? Or another option, I would have to bring 12V photovoltaic, one-to-one, through a window or thin wall(camper)?
You can use resistors /regulators
Wich two coils do i connect together the one that has alot of L or the one that has minimal L( i am confused by the circuit diagram🥶)
Both
Reducing the diameter and turning it slightly rectangular makes it powerful i think??
We have to check that
can i attach wires to the inductor legs, so the led is not directly on top of it?
Yes you can add like that
Could you help me? I’m trying to do the same thing but it’s not working for me. I made a short talking about it. You can see my set up
I can help you. Please check the video description, there are links to contact me
I wonder if this can be scaled up to be effective in say 1 meter X 2 meter applications.
Not possible
Why transistor opens or closes?
There is a constant voltage and there is no reason for transistor to open or close. single transistor oscillators don’t work this way.
There is a capacitance
How big can you go with this? Just need to make the coil about 5-10 inches and than I was going to buy the bulbs.
I dont know about that distance . It should work therotically
Oh I was reference the radius not distance of lights to the coil. Not sure if the bigger you go with the coil the more battery you need
im using bs 170 transistor and previously it used to work but now it isnt what should i do and deos the led have to have the same num of coils as the transmitter
Maybe your transistor got damaged.
The LED side should have a higher number than transmitter
@@EDISON_SCIENCE_CORNER how do i tell if my transistor is damaged?
Check the transistor using multimeter
Can we make this ring bigger then the size shown? so to cover more area. can we add voltage more then 1.5v and what is max limit?
It will increase the distance
You might need to shift to a MOSFET instead if you require high voltage
i wanna try this but i want to know if what if my source is 5v? any changes on the capacitors and all?
You can give 5v change the resistor
turn this as a wireless distance measurement device, directly read from the voltage level at the Hz frequency
Okay
Thank you very much for this tutorial it really help
And can you please explain why we're using that amount of resistor and what changes we need if we want to change the spec for example I want to make it 5v what should I do?
I used that resistor to decrease the base current if you want use this in 5 then connect a 1resistor in between your suppy and circuit
Sir adipoli
Thanks
I must've built this many. ways...I can't get it to work! :(
You have to use insulated wires, correct transistor , coil ratio etc.
@@EDISON_SCIENCE_CORNER finally got it to work…I used a 2222a npn and it worked! Tried many bc547’s to no avail. And, yes, did have proper pinout. Thank you for your response.
Is this working of Electro magnetic induction ??
Mutual induction
may let me know if I want to change the size of the transceiver and increase the distance.
You can increase the distance by increasing the size and increasing the number of turns
@@EDISON_SCIENCE_CORNERso would a smaller diameter + turns work better? I’d like to have my leds around 1 foot away while maintaining brightness
Bro make fm transmitter and reciver
Please
With Arduino uno
Will do bro
Apo namal eadhu copper diameter venamengail use cheyamoo ?
Yes bro use cheyyam
Can you make a commercial version of this wireless leds ??
What bro
@@EDISON_SCIENCE_CORNER can this wireless led circuit be made for commercial purposes??
We cant
You might be able to, but making something commercial usually takes a lot of work. Especially in safety regards and licensings or such. There are some commercial ones already I believe ^^
what happens if i use a 0.4mm wire ??
You will get the same result
What's the led name
Smd 0805
No its works only If i move the Wire
On - Not for all time whats wrong
Move the wire means
@@EDISON_SCIENCE_CORNER
i have a Transmitter Coil: 15 loop 15
Than I conncet "loop" to Plus
Transistor Bc547 Emitor to minus
Collector on coil
Basic ,too...
But nothing is happening
The transistor is Not defect and Not wrong placed , i test it:
-i conncet addly a LED on minus , than to battery.
- If i holt my Finger on basic and plus, the LED starts to glow
But my coil dosent make Induktion :(
Whats wrong -??? i build it - like this Video
Can you help me?
How the battery - and + , where ?
Please check the circuit diagram bro
കൊള്ളാം 👍👍
Thanks
does I need to be BC547?
Yes
@@EDISON_SCIENCE_CORNER ok
How can find the - +
Just connect no need to worry about that
220 uh inductor or what
Yes
