Some comments regarding the charger article:
This was a good learning exercise but not a design that others should copy, yet. But it is good to see someone building something and making the effort to lay out a PCB.
User's need to be aware of apple's bastardized chargers as chargers you see in stores may be standards compliant or apple bastardized and they rarely tell you which and this can lead to some unpleasant surprises. You can tell which by cutting a USB cable so you can probe the 4 USB leads with a multimeter. A short between D+ and D- means you have a real charger. Resistor dividers between V+ and GND on D+ and D- mean you have a non-standard charger. And neither is another form of non-standard charger with no signalling. If you have an apple charger which can be opened and resealed (or which you plan to use the bare board), you can fix it by removing the offending voltage divider resistors and shorting D+ and D- with a solder blob or jumper.
