Look Mum no wires These wireless LEDs will blow your mind

We re handling some wireless LEDs pretty amazing stuff. Again we re sponsored by I saw these LEDs on the Tested channel originally and decided that I had to have some. You can buy them here from Aliexpress (affiliate link): If you want to make your own LEDs then a 2. 2mH inductor and 220pF capacitor seem to work well you can see how to do it here: The mystery chip has been identified it s a XKT001 and it s actually controlling XKT333. आदतय Aditya महदळ Mehendale points out: The XKT333 looks suspiciously like a MOSFET. I suspect that the 6, 7 pin chip is, are the brains and the XKT333 s gate (pin 8) is driven by pin2 of this other chip with a squarewave. The duty cycle of the square wave is likely 44 hence (average) on this pin.
