Look Mum No Wires - This 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 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 XKT-001 and it’s actually controlling XKT-333. आदित्य Aditya मेहेंदळे 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 square-wave. The duty cycle of the square wave is likely 44% - hence ““ (average) on this pin. --- If you’d like to help support the channel then I have a Patreon page: And if you’re shopping on AliExpress or Amazon then if you click on these links I will get a little bit of affiliate money: Aliexpress - Amazon - You can also join us on Discord here: And we’ve got an exciting new newsletter!
