Building an LED Hula Hoop From Scratch
I'll save you a read if you don't care about details. Long story short - buy yourself a quality hoop from Hyperion. Save yourself the trouble of doing this, because frankly, the results we obtained were not that impressive. We spent around $800 in materials by the end of this project and ended up with a heavy, bulky, large, cumbersome hoop that broke after 10 minutes. Seriously - just get a good hoop from a pro.
Our final result, starring my girlfriend Amanda:
It broke shortly after this video. We tried to make a wireless one after this, but didn't have much luck. I eventually said screw it and bought a professional hoop for Amanda.
Here are some shots of when we were building it.
Matt and I measuring LED's... and drinking.
Matt is a whiz with hardware. I just hold things and ask dumb questions.
Working on the code:
You can see the code we used on Github - I'm warning you, this is bad code. https://github.com/pengii23/myledhoop.com
It's an assimilation of a bunch of LED scripts we (pengii23 and I) found floating around by other people who had attempted making a hula hoop.
It's really, really bad to go back and read this stuff.
You've been warned.
Yup, really. On the plus side - look at that video up top! Lovely.
The moral of this article: Don't do it yourself. Buy one from Hyperion. Seriously. You'll love it, and it won't suck like the one you'll build.
