iPhone Battery Charger / Tester Breakout and HDQ Gas Gauge Stats

Troubleshooting iPhone problems can be a daunting task sometimes considering how complicated they are. It’s easy to overlook the simple things and on occasion you may replace parts that don’t need replacing. Batteries are no exception. I have seen technicians often replace batteries when they may not necessarily need to be or ignore the fact that they could be the cause of the issue at hand. To remedy this I designed a basic iPhone battery charging breakout board system. The system can charge a battery, has the option for expansion to support newer/other batteries and breaks out the battery status pins which can be read from a microcontroller or some other means. It consists of 6 battery connector boards (iPhone 4, 4S, 5, 5S/C, 6, 6+) and a main charging board.

Expanded Zipit Bottom Case: my first 3D printing adventure

3D printers have been around for quite a while now. When I first read about them I had a million ideas for things I could make. Unfortunately the introductory cost and learning curve were too much to bear. My 3D buzz wore off and the world continued on perfecting the new technology. It’s 2016 now and after seeing this article on Hackaday about a low cost, decent quality beginner 3D printer, I decided it’s about time I do something with 3D printing. That brings us to the Zipit. The original batteries for it are not available and finding a suitable replacement is not easy either. Let’s make a replacement bottom case for the Zipit with more room for a bigger battery.

Troubleshooting & Reviving Single Cell Batteries

There’s a lot of hubbub on the internet about charging Lipo batteries and how dangerous it can be. It can be, but if you take some precautions it’s perfectly safe. Charging Lipos safely typically requires specialty IC’s to ensure they don’t explode. All devices with Lipos (smartphones, tablets, laptops, etc) have these charging chips built in to protect the device and the consumer from an oops. The batteries themselves also contain a protection IC. The IC’s are great but can be over protective. I often get phones and tablets for repair with “bad” batteries that just need a little coercion into working again.
