Thanks @Majenko, I'm gonna solder those joints. from your comments at the bottom: I don't have a regulator on hand and I was wondering if I could use the equation here learn.sparkfun.com/tutorials/voltage-dividers to use as sort of a rough regulator...would that be unsafe...I guess i'll solder and then try again just to make sure it wasnt a connection

Not for power, no. Logic signals only.
