"Festipedia is dedicated to recording the history of the Festiniog Railway from the 19th Century to the present day. You will also find much detail on the Welsh Highland Railway." I hadn't realised quite how big the FR/WHR is now -- I need to find an excuse to visit at some point!

A collection of (mostly) commercial diesel shunters, with detailed articles about their mechanical restoration. I now feel less worried about the space my instruments and computers take up -- at least I don't have 17 railway locomotives to find homes for!

"I study the Digi-Comp II, a wooden mechanical computer whose only moving parts are balls, switches, and toggles. I show that the problem of simulating (a natural abstraction of) the Digi-Comp, with a polynomial number of balls, is complete for CC (Comparator Circuit)". A nice short example, with some interesting discussion on what the Digi-Comp can and can't compute and why.

90th IDPG Manuals edit / delete
A variety of US Army manuals. I came here via a link to the one on watch and clock repair -- but the manuals on how to run an army band (including instructions for violin repair and the instruction to avoid "violent, enervating jazz" when planning hospital concerts) are also fascinating.
