Bought a prison laptop on eBay. Thought it should be just some generic laptop with a clear shell, turns out it's actually a bit more than that. Out of the box you get a laptop that basically doesn't do anything other than asking for the password. It doesn't have hard drive so obviously there is no operating system loaded. You can not even easily install your own because there is no USB port at all:

Quick weekend project: I have many LCD modules in my drawer. When I am feeling stressed out/ burnt out, I would just randomly pick one from the drawer and try to make it work. So, today I have got this small LCD module, with no datasheet or any documentation: The backside of it, no identifiable LCD controller or driver chip. The connector has 25 pins. Searching the model number showed me that the manufacturer has gone bankrupt more than a decade ago, and it's being used on some data terminals, with a resolution of 160x128.
