Mandy, I am your father…

I could turn this post into a commentary  about the importance of doing a thorough literature search, and despite how thorough you think your literature search is, it is not thorough enough.  Alternatively, I can make some Star Wars references; let’s go with that.

Soon, my wife and I will buy our first home.  My wife and I just bought our first home.  I have been looking at videos on how to paint rooms and found myself looking at periodic-table wall-art.  I came upon this website which was coincidentally published one year ago today.  Until now, I had not seen an RGB blinky-light periodic table besides Mandy, and it appears as if Mandy was coming to life just as apaf1 (send me your real name and I’ll edit, if you wish) was completing his project.  What does that mean for Mandy?

Happy Holidays – from Mandy

I am teaching Mandy to sing (sort of).  Here’s Mandy playing along to Carol of the Bells in what may be the worlds “first” Periodic Table spectrum visualizer.  Now, before we blow up the Twitter sphere with allegations that Mandy belongs on the Top Ten List of Most Infamous Lip Syncing incidents, I’m not claiming that this is live.  Mandy wasn’t designed to do real-time spectrum analysis (she’s a Periodic Table, after all) but I wanted to see if some geeky visualizations would be possible.  So, I created my own version of Carol of the Bells (written in Sonic-Pi) and then analyzed the audio file using Mathematica, which has a neat function, SpectrogramArray[], that provides easy access to the frequencies in an audio file.  I then binned the frequencies into 118 buckets – one for each element on the periodic table, and converted the intensities into colors (blue for high amplitude, red for low amplitude).  I probably should have thought a bit more about which elements should display which frequencies, but time was running short so I simply made the heavier elements have the lower frequencies.  In any case – enjoy.
