Hey, remember I was mentioning 0-ohm resistors yesterday? Here's one!pic.twitter.com/0O8S0Uzf75

So, the keyboard, the reason we're here... It uses a flat flex connector, since it's directly on that transparent material that all cheap terrible keyboards are. 11 connectors.pic.twitter.com/ATwgnq7hEz

You can see a bit through the back that there's separate pads for each button, so I can already guess how this works. It's two flexible plastic layers, with contacts on each, which touch when you push them down.pic.twitter.com/rPjgzWPab4

Here's the fun part, though: when you look at the top, there's no gap here... they put this together and glued it on. There's really no way to remove this that doesn't destroy it. So I can't just look at the button matrix and reverse it, unless I want to buy another otter.pic.twitter.com/XqrreIMwLA

But hey, we can do educated guesses and then test 'em. We've got 4 rows, 7 columns. Hmm, what does that add up to? oh, yeah, 11... this is just a simple matrix.pic.twitter.com/XU9vmwCFhI

But I'll need some way to connect to this thing. Now, normally they just do that horrible flat-flex-to-PCB press fit thing, but here there's actually a really simple answer to the "how do I connect to this" question...pic.twitter.com/jMs8huX0Dz

I've got the connector right here. I just need to desolder it from the board.pic.twitter.com/CfYCTHsLZU
