    Wow! That's super impressive that you made this as a history major, I assumed you had a strong electronics/electric background.A couple more questions, you mentioned that you used a 2mm barrel jack, I think you meant to link to a barrel jack product, but your link was actually a power switch. What type of barrel jack did you use something like this (https://learn.adafruit.com/led-art-with-fadecandy/wiring-your-leds)? Also, I'm assuming any 10A5V power supply will work, but do you remember which one you used? Finally, do you have a circuit diagram that indicates where the capacitor would hook up to? (Btw cool idea incorporating the potentiometer into the device) Thanks for being so helpful in answering my questions!

    I'm just a little confused, because if it wasn't able to run via USB cord then you would have to buy a 5V 10A power supply in order to run it? In addition, I was wondering why you used a potentiometer and capacitor? And do you have any suggestions for what kind of SD card module to use, in addition, I'm assuming you're using the 5v/16MHz Arduino Mini Pro (https://www.sparkfun.com/products/11113)Sorry for all the questions, I appreciate you taking the time to answer them though :)

    Thanks for replying! How were you powering this before adding the external power source (the 5V)?
