Converting A Lame Tron Toy Into A Cool Halloween Costume Prop


Instructable user [cubeberg’s] daughter saw Tron:Legacy earlier this year and decided right then and there that she wanted to dress up as Quorra for Halloween. Being the awesome dad he is, he decided to make her costume himself, and hit the stores in search of an Identity Disc to complete the look.

The toy was pretty underwhelming, and lacked the lighting that a proper Tron prop should have. He figured he had the skills to make it a bit better, so he gathered some tools, a bunch of LEDs, and set off for his workshop. He gutted the disc, cutting out any extraneous bits of plastic he could find. He wired up 64 LEDs between the disc’s inner and outer ring, which he controls using an ATmega 328 paired with a Max7221 display driver.

He doesn’t show any pictures of what the toy looked like beforehand, but the final product looks great. We bet that his daughter is pretty pumped for Halloween to roll around – we know we would be.

  1. Nothing impresses me more than a man that wants to spend quality time with his daughters. As a man with two daughters, I can appreciate just how awesome daughters are. Too few don’t. :(

    He could have just used LightTape though; that’s what they used in the movie.

    It’s not terribly cheap but the result would knock the crap out of what LEDs can do.

    that said, I fully respect this, and I wish one of my daughters had asked to be Quorra for Halloween. I probably would have used LEDs also.

      1. The deluxe model has 8 leds, a speaker , two switches, what appears to be a mic and a controller hidden in a blob of plasic. power is from a 6 lr44 button cells.

        I had a few ideas, like make it into an electronic tamborine, or possibly program somesort of game. And it would be cool to add different color leds so the lights can change color..

  2. We did this at Harford Hackerspace 9 month ago (before the movie even came out). I submitted it to HaD but they never posted it. I’m curious as to why that is? Was it because the original article was hosted at channel9 and not instructables?

    I’m happy to see that a few people have taken our plans and made their own version of the tron disc. We have since updated our disc with a Netduino Mini and an accelerometer from a knockoff wii nunchuck.

    1. Did you ever post an update of the project? I’d love to see your final version, but I can’t find anything on other than the initial version with the standard Netduino. Details about the accelerometer addition would be fantastic.
