Not quite the same board as I have. Mine has a power switch and some sort of power connector mounted to it that shows out the back beside the USB connector.

I'll have to wait till next payday to get the power supply, unless the junk guy turns it up. He says there is some more stuff from the same source he hasn't sorted through yet, but he has his eyes open. That's how he found the other two spools of filament he gave me. One is white. The other florescent green.

This shop is quite a sight. His wife was sorting through a box of children's clothes. "Why do people do this," she laughed. "Here is a nice canvas tennis shoe, but only the left. How many size 3 boys do you know have only one foot?"

I went looking for an electric skillet I could use to reflow surface mount parts as mine had gone missing. He didn't have one, which is good because I found mine.
