ZipPi Power Supply

The MOSFET I wanted to use doesn’t provide much current at 5V. I’d seen the graph but my eyes had passed over it until Mat read it off, and then I understood what it meant and why it was important. And, y’know, why I should pay attention to the fact that graph is an upward curve. More voltage means more current – and I want to run the Pi at 5V through the USB power supply. It’ll protect it best, and allows for most flexibility. .7A is not enough.

Mat gave me the right sort of MOSFET, although he did insist on breadboarding it himself. I say I’m just teaching silicon to respect me.

Learning out of this: graphs are probably important. I should look at them or something.
