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?
Great,but where do you calculate the required frequency of resonance of the coils? Without frequency matching the LEDs get a fraction of possible power
@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
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
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?
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.
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?
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?
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
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?
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.
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 ^^
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
@@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.
@@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?
