- Hi there! In this video I will show you how to create your own wireless LED.
Iam using cd54 470uh smd inductor and 1nf smd ceramic capacitor for the receiver.
Working frequency: around 200KHz
transmitter coil inductance: 50uh
Induction distance is about 10cm for the red led. induction range may vary depend on the color of the LEDs

Excellent

For the transmitter, is it possible to use an arduino to generate the same effect as the circuit? I have the same smd 0805 components for making the LEDs (470uh and 1nf).
Can you make an 360 light with this ? Like you have yo add more smd.
Hello, I made the circuit, the z44 does not heat up at all and the circuit works great, but the 3525 gets hot, can you help me know where the problem is, or is there a way to make it not hot?
hello there can you please answer few of my question?
1. Can i use smaller inductor like cd32? Do the size affect to result?
2. Can i use another frequency like 180kHz? i mean changing the value of inductor and capacitor? And if i can what should i change?
1)Yes, you can use cd32 inductor but it may reduce the range.
2) Yes, you can use another frequency, Use LC calculator to find the value of inductor and capacitor.
@@ElectroRetro thank you for your answer, i wonder if i change the frequency so i must change value of C1, C2 L1,L2 and they must have them similar frequency right?
Yes,

@@ElectroRetro thank you so much, by the wae can u share the schematic? i cannot find the sg 3525 on altium and proteus :(

Hi there i try the circuit it worked but just few minutes before the mosfet is too hot and burned. Do you have any ideal about that?
What's your inductor value?
Try winding more coils on transmitter side.
See your odyssey comments for the above video
I use 12v source when plugged in, it drops to 4v, I don't know how to solve it
Check for any short circuits
@@ElectroRetro it still lights up the led no short circuit but I don't know why it's a bit weak should I wrap a few more turns of wire
@@luutrung786 Try it
@@ElectroRetro ok i will try it thank
what if i need 5v only?
Sg3525 wouldn't work at 5v.
