Russell Jones from New Jersey wrote in with his cool-looking LED lamp:

I had a bunch of BNC right angle, straight, and T connectors, so I decided to make another lamp.



I didn’t want to purchase anything for the lamp except the polycarbonate diffuser rods, which is McMaster #8571K44. The 5/16″ diameter rods were cut to length and a 3/16″ hole was drilled through the center to fit over the LED.



The individual blue LEDs have a 68 Ω resistor soldered in series, and a 5V power supply to the entire thing with the center as the positive rail. Wiring LEDs in parallel can be a bad idea, so the resistor is out of necessity. The LEDs were sanded down to size with a dremel. Click the pictures to make them big.
