Nokia N900 Necromancy

I have such fond memories of the Nokia N810.

I did my master’s thesis on that device. I had a custom hypervisor running a guest kernel, virtualized networking, and a buildroot userspace. I could SSH into the host N810, then SSH into the guest. I even virtualized the framebuffer at some point and got the “dancing baby” animation playing from the guest. It only ran at a couple frames per second, but it was _amazing_.

The only weird thing about it was that you couldn't charge a fully empty N810 with the micro(?) usb charger. It'd charge just enough to boot and then crash again, because it couldn't wake up far enough to negotiate a higher current with the charger.

Had to use a barrel plug to charge it.

Spent a very nervous and sweaty day figuring that out when I bought one used with no warranty or returns and it didn't boot properly =)
