I think everyone working with ribbon cables and non boxed headers will have plugged in the ribbon cable wrong, either upside down or offset by 1 pin, at some point. Usually no magic smoke escapes, fortunately.
Regarding the dodgy decimal on jmedved's board, ..
Mailbag galore.
Dave screws up and releases the magic smoke on the best mailbag item ever. Turns a light bulb on with his mobile phone, and goes underwater in a submarine.
And a cameo appearance by everyone's favorite.

cheer up Dave - try this http://ldd.lego.com/en-us/ Lego CAD !!! - so good to be a dad.
Too bad Lego removed the link to the Pick-A-Brick store. I have designed several things with LDD, but it's a bit of a gamble what colors are available. Really annoying when you selected some bricks and they turn out to be unavailable....

Have you tried bricklink.com?
This just popped in to my inbox: http://dx.com/p/usb-av-usb-power-current-voltage-tester-translucent-blue-silver-235090
USB power meter for $6.40 delivered. Arguably not as good but I found the timing interesting.
Looks interesting. I checked http://jmedved.com/usbamps , but looks like he doesn't sell it. I was thinking about to ask him, if maybe a Kickstarter project would be a good idea, but you can't compete with such a low price, at least not if it doesn't have some added value (any ideas?). Good for my USB device development.
