Making a custom flexible USB led
Building a flexible USB led. |
The USB connector provides 5 Volts. After selecting a led your own choice add a small resistor to limit the current. Shortened the legs of the led and added long red and black wires for power connection.
Led and resistor with red and black cable and flexible hose. |
A flexible oil hose (also available on Aliexpress) is used as a housing to make it flexible and stable at the same time. In this version i removed the connectors from the hose. It is also possible to change the hose length.
For the power connector i used also some USB connectors from Aliexpress, an USB connector from an old cable can also be used.

After soldering i pushed in the USB connector back in the hose. With the correct wire length the led will just pop out of the other end of the hose. With hot glue the USB connector is glued to the hose.
