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.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
