DIY Wireless Charging Cool Light [Copy link]

 

While on vacation at home, I used old components and materials to DIY a simple and cool lamp with wireless charging.

Materials used:

• Fake fruit earphones wireless charging box
• 3V LED Light Board
• 20 ohm resistor
• Toggle switch
• Transparent plastic snack jar
• Strong all-purpose glue

Production process:

The production process is very simple. Disassemble the wireless charging box of the fake fruit earphones, keep the wireless charging part and the battery (be careful not to break the magnetic isolation sheet), connect the LED light board to the battery through a toggle switch and a resistor, and dig a hole for the switch on the snack can. Finally, fix it with super glue.

The LED brightness can be adjusted by connecting a resistor in series. The smaller the resistance, the higher the brightness, and the shorter the battery life. Using a 20 ohm resistor, a 400mAH battery can work for more than 6 hours.

I couldn't find the LED touch control chip at the moment, otherwise I could make a touch-dimming LED lamp, which would have a better effect and wouldn't require digging holes.

The base plate in the second picture is so big, maybe it is recycled?

Yes, I bought most of them online, the cost is very low
