I'm interested in the results of this, but I'd suggest holding off and posting this to HN (and elsewhere) when the task is done. At the moment what we've got here is a goal and a disassembled laptop with absolutely nothing hooked up to the Pi, which is not really that interesting.

I'd also suggest that sufficiently interesting stories about why you couldn't manage to do this would also be interesting. ("I couldn't ever get the adaptor"... probably not interesting. "So I had to 3D print it, which was harder than I expected."... interesting. "I tried for weeks to get the RPi working and it almost sorta worked but it was only in monochrome and I couldn't figure out why."... interesting, and probably enough to trigger other people to want to help!)
