  • The former US distributer for Sarantel was Jim D Gray & Associates http://www.jdgagps.com/. When Sarantel went out of business, they bought as much stock as they could to support their customers. As of Jan 2015, they had a small amount of parts left and can build up equivalent antennas.

  • For most of the Intro to Arduino and Wearable Electronics classes I've taught, installing the drivers (including FTDI) has been the biggest obstruction to getting new students started. Particularly on older Windows machines. I finally started requiring students to bring in their personal computers to ensure they'd have access to help while they install it.

  • technically you can power an arduino with 5V directly into the 5V pin. BUT it is risky. There is no input protection on the 5V pin so you risk damaging your arduino if you run external power into it.

  • 0 Ohm resistors are very commonly used in professional engineering design. They typically have two purposes - 1) you can change the resistor value later if desired. Or, 2) you can use the location as a machine-populated jumper. Then you can save money manufacturing PCBs by designing a board that does several different things, but some features are only enabled if the assembly specifies including that 'resistor'.

No public wish lists :(
