Not been online much since I was travelling to the UK - sorry to hear this John, it can't be much fun sitting around bored. I hope that 2017 is a much better year for you.
Couple of things I could suggest if you are very bored, although not sure if this is of interest to you.
Grab yourself a secondhand X52 Pro flight control system for a PC and learn how to fly (if you can't already) with DCS world. They have a Spitfire addon which requires you to fully master the plane. A complete startup procedure is required (fuel pump, priming, ignition coils, etc etc). My girlfriends father learnt to fly with this sim, we bought him some flight time at the local airport and on his first go up he only needed slight corrections on landing. Maybe this would be something to look forward to after the year is up? I'm about to buy a new 1080 Nvidia card so I can hook up a VR headset, I'd happily donate and ship you my Nvidia 970 GTX if you need a graphics card

Another idea it to buy a cheap desktop 3d printer, couple of hundred quid or less, and design up some models or useful bits. There are lots of existing designs on the net you can adapt, pretty interesting learning curve.
You could sign up to an online course and learn something new: https://alison.com/ https://www.udemy.com/
You can also learn Raspberry Pi - plenty of cool things to look into https://thepihut.com/
