I’m currently building light sabers (and robot armies and image processing frameworks and visualization libraries, and..), and right now, I’m working at prototype IIb.
Prototype I used tape to connect a Nunchuk and toy sword, and wire to go to an Arduino that is connected to the PC with wires.
Lightsaber prototype II is based on a really cheap thing from Amazon. It will get a laser-cut case for a standalone Arduino Uno that talks to a Nunchuk (a 17€-movement sensor from Wii) via Serial Interface and to a IR helicopter. It has a battery case.
I’m currently writing down very detailed instructions on how to do this, and will post a series on this. Link one is here already. Meanwhile, I’m also working on Prototype III.
Prototype III will change to two Arduino Nanos (or a Raspberry Pi, I’m not so sure), include an XBee shield for wireless communication with the PC (Bluetooth seems to be a good bet, because I want to use the 2.4Ghz for a robot swarm someday), and two Nunchuks and touch sensors. Any IR communication will be done with the PC. I’m thinking about using a laptop battery – lasts forever, is relatively stable as a voltage supply), nice to charge, and fits into a sword. (But then, I’ll have to protect that battery. Don’t want an exploding sword.. although… the ideas I have 😉 )
I recently gained access to a laser cutter via the fablab in Munich.
Regular light saber designs are a bit unrealistic right now (but I’ll be moving to SMD, which will make things smaller and more comparable to the real technology), so I allow myself to be inspired by fantasy swords.
I am using plexiglass, and wood. I engraved this plexiglass panel with my logo. I then used some regular LEDs, and backlit the panel – like in this project.
I will include holes for just fixing the two plates together, and will be filling them with sugru.
Yeah, that’s my final update for today.
