Hey guys,
I'm building an inductive charger using Adafruit's Inductive Charging set (link below) to charge my Astro A50's. I've got it set up so that the 9V DC plug goes to a set of alligator clips which then connect a NO momentary switch, which then connects to the inductive transmitter. Last night everything was working fine, but today something went wrong. When I connect the pair of alligator clips and test the connection right with the momentary switch open there using a voltimeter, the voltage reads 9V. Then if I close the switch, the voltage drops to 0V, but spikes every couple of seconds to somewhere between .1V and .3V. Also, the headphones will power on from the current being sent to them, but apparently it isn't enough to keep charging it after that.
I can't for the life of me figure out whats making this happen. All wires are connected to the correct polarity, there aren't any shorts as far as I can tell, and I don't know what else it would be. As I said, everything was working perfectly fine last night. Does anyone have any ideas?
