    tulip apparently.

    "When are you going to tidy this tulip up?"
    "Have you bought more tulip?"

    "Oh no, not more tulip!"

    Pint glasses, stolen from pubs. Got about 80 or so in my collection, each of them with a unique label/brand on

    I did hear someone on tha radio at the weekend, saying that although genius-level masters at anything are very rare indeed, "ordinary" masters of most skills are much more common than people think, and will work for much less than people might expect. And, he added, success belongs to those who realise that.

    Books, especially science fiction novels.

    I wanted to build a 40MHz one* out of Practical Television but, as ever, never got around to it.

    *It used your bog standard VCR97 of immortal memory, and a distributed amplifier using EF184 valves to get the bandwidth.

    The usual homemade scopes of the era had difficulty reaching 5MHz.

    I still have 3 or 4 VCR97/ACR13 tubes in the loft.

    In fact, it's in this:

    Practical Television Circuits : R.E.F. Street : Free Download & Streaming : Internet Archive

    The distributed amp is on page 338.
    VCR97 naturally
    EF80s I should think.

    Out of a book, or perhaps cobbled together from various articles + books, depending on what I had or could get from the surplus shop. Can't really remember: it was just about the date that book was published.


    I did it for a school physics project, and got an A. I also showed the Lissajous figures (compounded, clipped, and phase-shifted) to the Art teacher and he said I should put them in for a project in Art too. I never did, shame, it would have been nice to have combined the Two Cultures in one project.

    My pride was creating a proper s-buffer implementation so you didn't have to depth-test every pixel, but pre-built a set of pixel runs as you processed polygons, before rendering all those runs. Avoided a z-buffer entirely if memory serves... it was probably 17 years ago so I forget the details but it was my first real proud achievement in programming.
    I too did all that stuff a few(make that 25+) years ago in 68000 and 8086. I'm now doing the same thing with an ARM :-)

    Btw, VGA "Mode X" ftw!

    A lot of my interest and ability with computers is a result of using them, or wanting to use them, to investigate really interesting stuff. Which I still do from time to time but it's not my day job unfortunately.

    I only ever had one, but I did build it myself. I made it graph transistor gain. But the Lissajpous figures were much more interesting.

    The last time I had a ride on the Keighley and Worth Valley Railway I bumped into a former colleague who was a guard on the train.

    I could certainly see the appeal of renovating old machinery.

    As Ian Fleming put in it one of the Bond books (The Man with the Golden Gun?), one of the points of being really rich is that you can afford a full size train set.
