Since we just learned that Star Wars: Episode VII started filming yesterday (it’s really happening!), it seems like a great time to look at another lightsaber build. Instructables user agent036 used plumbing parts for the hilt and took apart a toy lightsaber for the blade. Between a sink drain, a plumbing extension tube, some wire, and other odds and ends, he made a hilt that looks much more realistic than anything you see on toy store shelves. Before you dive into wiring, piece the hilt together is pretty straightforward:
The Pop-Up Drain, and the Extension tube. These two parts are magic. Just sticking the one on the other looks like a light saber. What I did was I removed the plastic and brass rings from the drain, and then wrapped a bunch of rubber bands around one end to build it up so I could squeeze the extension tube on and have it stay. There are lots of ways to do this, I just had a pile of rubber bands handy. You could use gaskets or taper or whatever. Now unscrew the bottom tube from the drain to make it easier to get into it.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
