Neat Instructables tutorial from allie.fauer! Would be a great addition to any Harry Potter themed costume.
One night about a month or so ago, I was watching an episode of The Big Bang Theory. In this particular episode, Howard and Raj were controlling their TV using a MAGIC WAND TV REMOTE!!!!!! Upon witnessing this sheer awesomeness, the preteen Harry Potter Fangirl inside of me had a minor heart attack.
Of course after seeing the episode, I did a quick google search to see if this Magic Wand TV Remote actually existed, and I came across the Kymera Wand. I was tempted to purchase this product, but decided against it. I had been wanting to learn how to work with Arduino for quite some time, so I decided that making my own Magic Wand TV Remote would be a great way to force myself to do just that.
In case you are not familiar with the Kymera Wand or the episode of The Big Bang Theory that I mentioned, a Magic Wand TV Remote functions without pressing any buttons. By waving the wand in different ways, different commands are sent to your television. I have programmed my Magic Wand TV Remote to turn the TV and cable on and off, control HDMI functions, and to turn volume and channels up and down.
