    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 :(
