solder so many wires)<\/li>\n\n\n\n<li>Change layout of power supply (currently the screens brightness will dim if you turn the speaker volume up to loud)<\/li>\n\n\n\n<li>Find buttons with less travel for the D-Pad (the cross plate moves to much and can slightly dislodge the 1&#215;4 flat plate underneath it)<\/li>\n\n\n\n<li>Move volume pot-meter a couple of millimeters to the left (just for visual)<\/li>\n\n\n\n<li>Change i2s to mono output, (thought i could do it in software, but i should have done it on hardware by (theoretically) adding a 634k\u03a9 on SD_MODE to 3v3 on
