1995 Rover 220 Coupe Turbo Pictures

There's a mix of photos here, as some of them (the private plate) were taken from the original advert for the car. The later ones were during my ownership.

1992 Rover Metro GTi Pictures

These pictures were taken a long, long time ago (1999?) with a very early digital camera (not even 1MP resolution), so hence they are really quite crude quality compared to anything available now!

OO Gauge Train set and scenery

So this is a surprise Christmas present (2019) for my wife. She had told me that she always wanted a train set when she was a child, and had to settle with playing with her cousins set instead.

I ended up buying a Bachmann Digital branchline starter set (Class 25 diesel and two period-correct passenger carriages) as well as a freight engine (Bachman Class 57 diesel in Freightliner colours; her dad worked for BR and then Freightliner):

I also bought an extended loop of track, plus additional bits and pieces to put together a more complex setup.

Z180 Mark IV Single Board Computer

There is a thriving community of enthusiasts who design and build their own computers from scratch, not just buying ready-built parts, but laying out pcb's, writing the firmware etc.

Check out:

A few years back I thought I'd have a go at assembling my own system from some of the designs on that site. I chose the Z180 Mark IV, a turbocharged variant of the venerable Z80 8bit processor with a memory management unit, 512KBytes of RAM, a multi-slot backplane and modern(ish!) storage, keyboard and display support.

DIY Spraybooth

Since the move to the new office, I haven't been able to do any painting of models, as I had no way of using either spraycans or my airbrush. IN the previous office the size of the desks meant I could have a fairly ghetto setup with a huge cardboard box that I could spray into. Although I had no extractor, at least the paint (mostly) didn't go everywhere.

There are plenty of (cheap to very expensive) spray booths out there, including a very common one (under £70) that does pretty much everything I want:

However, the problem with this design is that the air is extracted out of the back of the unit. This means that you need quite a sizeable depth of desk to use it on. I don't have that:

I have a maximum of 75cm, front to back, and not a lot of free workspace to have something like that permanently in-place. What I needed to do was to build something like that, but that would fold-down even smaller, and with a top-mounted extractor to leave me without the depth issues whilst it is in use.
