The Pine people are sending a new keyboard, but said they won't replace the 
new one if it dies.

How hard is it to repair a Pine keyboard? Yifei is really good with a 
soldering iron

You can replace that regulator. But it's surface mount. I killed my keyboard

I've given up on the idea of surface mount soldering. I'll get Yifei to help 
me whenever I need such stuff done.
