I'm trying to make a life logging camera because the products sold for life logging is rediculously overpriced.
Basically, a lifelogging camera is just a normal camera with a rediculously long battery life and storage.
So I bought a Keychain "Spycamera" from China and I'm considering removing the 3.7V lipo battery and replacing it with a USB Power Bank(5V, 2A, 10Ah) so the camera would last a VERY long time. I'd put in a 16gb microsd and I calculated for the low resolution, I'd be 4GB/day or ~1.5TB/Year or ~100TB-150TB/Lifetime.....pretty good to be able to have a record of an entire life.
But I'm having an issue with the USB Power bank. It charges my phone just fine which means it is producing current, however when I try measuring the Power and GND pins of the Power Bank, it shows 5V, and basically 0A of current....No current at all!!!
I assume it has some sort of short protection but I've tried putting a 1K Ohm resistor in series and it's still 0A.
I took a microusb cable, plugged it in, and cut off the end to expose the Red and Black wire, measured the voltage, 5V and the current... 0.
I NEED the 2A or at least 1A...
I'm not sure what to do.
***btw. My power bank is http://www.ebay.com/itm/10000mAh-Du...815890?hash=item3aa3a84052:g:vc0AAOSwEetV76E4
I noticed that it has a list of compatible hardware....which is odd cus it's just a 5V usb power bank, it should seem so obviously that it should charge any device that having a compatability list is making me question whether it has some detector in there that only lets compatible hardware get current?...,
