MiniPOV3: No lights turn on when powered on
I am requesting help on my MiniPIOV3 kit. It did not light after completing the kit and powering it on.
First, let me state, I have no electrical engineering experience and have never soldered. I have two children 5 and 7 and our family wants to join in on the maker movement. The kids were involved in every part of this kit effort except the poor soldering, which I take full responsibility for!
We used a lead free solder and a good quality iron from your store. From your tutorials I gathered that lead free is harder to work with, but with younger children I felt more comfortable with the lead free solder. After completing the kit we powered it on and none of the lights turned on. I did try another set of fresh batteries. Then, using a multimeter, I checked for continuity, by following the pcb tracings and found continuity a where, I believe, it belonged and did not identify any bridged connections. Though "not there yet" I figured I'd give you all of my information now in the case it later becomes necessary. I am using Mac OSX, a serial USB adapter from adafruit, no lights turned on at all when powered. I must confess that the last time I clumsily checked for continuity, I had powered it on and forget to turn it off. Perhaps, now I have really messed it up. Below are photos of the top and bottom of my kit. Thank you for the help.
