What is needed for a USB lamp?
Making USB lamps
Disassembling a light bulb. For this you need to pry with a flat screwdriver white dome. It is glued and should gradually move away from your pressure. Remove the internal board, it’s more for us it will not be necessary, we will have it.
Making a hole in the base for the wire with a hot soldering iron. You can just drill a drill.
Skip the wire to power the light bulb.
We now need to build a very simple circuit to power the LEDs from USB - 5 V.
We do everything on a piece of plastic. I have a small brightness, but if you want to brighter - you need to do everything on an aluminum piece of metal. For better heat removal from LEDs.The resistance of the resistors can be adjusted and the power of the LEDs, and hence their heating.
We glue our collected fee to the bulb. Sticking on hot glue.
Now we are assembling a light bulb. Glass can be glued to super glue.
This is how the finished USB-powered lamp looks.
