A longer USB cable (I cut the end of an old charger cable)
53 mm diameter ‘slim’ drink can.
Cut it into a 50mm high ring with a box cutter. Make sure the ends are flat and not bent. Watch out for sharp bits!
To Make:
Thread the USB cable through the side hole on the bottom. Make a knot in it so it cant be pulled out.
Solder the usb cable to the led strip. Test if the polarity is ok.
Cut the LED strip to length, along the dotted line on the back. I used enough to loop around the can three times for a bright but not too bright light.
insert the metal ring in the bottom part.
Stick the LEDstrip on the metal ring.
insert the Diffuser into the top part. Press it firmly in place. This is as tight pressfit!
Mate the top and the bottom parts. Rotate untill the metal ring is completely in its slot. Press firmly done.
