Disassembling Apple’s diminutive inch-cube iPhone charger reveals a technologically advanced flyback switching power supply that goes beyond the typical charger. It simply takes AC input (anything between 100 and 240 volts) and produce 5 watts of smooth 5 volt power, but the circuit to do this is surprisingly complex and innovative.

Arduino quadcopter iPhone control:
This Arduino Quadcopter by Kyle Fieldus has iPhone Control, similar to the AR Drone you can tilt the phone to control the quadcopter. Touch OSC is being used to design the phone interface, there is also an Android version available. The system chain is a bit complex since the phone is sending the input data to the computer, the computer determines what should be done on the quadcopter and sends these commands to a computer tethered Arduino via USB. The computer tethered Arduino finally sends the commands to the quadcopter mounted Arduino via Xbee. All of the code and instructions will be made available as soon as this University project has been handed in and graded. You can see the first video here that was taken when the Xbee link between the two Arduinos was tested.

Here is a montage of photos that I took while modifying my iPhone 4s to build in wireless charging. There are wireless charging options out there such as the powermat system but they all involve slipping on a jacket around the iPhone. I wanted to internalize the technology so that the beauty of the iPhone is not hidden away! It’s taken a while to complete but it’s finally done.

This app is a must-have for anybody in the Tech industry and or people who like to do it themselves. The new updated RepairDB brings a modest library of service manuals to the table. Being the first and only app in the App Store covering LCD’s TV’s, Laptops, DLP’s and more.
Many repairs do not seem worth their while because too much time is spent searching for essential service information. The required information is often not available or needs to be ordered, costing time and money! Shorten your repair time, save time and money when searching for important information.
Since identical failures often occur at some point in a large percentage of a given model or product line, using our app, may help identify the problem and or a solution.
