Riveting complete


Does anyone know anything about painting PC fans? Do you have to dismantle them first?

Don't try to paint them whilst they are running...

Or do, if you have lots of other stuff you want to paint the same colour...

You may have hit upon an easier way of re-decorating!

I wasn't a big fan of the green, but as it is coming together, I am liking the contrast and combination.

This so needs one of these in the middle of each side IMO



Then of course you will have to make extra features to justify the bends...... Tongue  Undecided

Looking good.

This looks like an interesting project, Lord Pentecost.  I don't know if you're planning on doing anything with the keyboard, but I recently discovered that there's an outfit that still makes the old IBM-type Model M mechanical keyboards, but slightly updated (e.g. with a USB plug instead of the old 5-pin DIN connectors).  I just bought one recently for my own soon to be worked upon project.


That sounds interesting, I was thinking of buying the keys from datamancer http://www.datamancer.com/cart/datamancer-typewriter-keys-p-276.html expensive but I just can't face making 100 odd keys individually. On the subject of keyboards does anyone know if it would be possible to replace the number pad with a rotary dialer from an old telephone?


The rotary dialer is an analog device, it would require an analog to digital converter.
It would also be much slower than touch buttons due to the rotary action.
You may want to consider one of the smaller 60-66 key keyboards, some of the keys serve dual purpose.

I am not sure if this comment has since been touched upon but to clarify, the old telephone rotational dialing mechanism is not truly "analogue" it is a simple interrupter.  It would however need a separate program to interpret the signals, there may be a in-line device readily available for such a purpose.  Many signal inputs use a decoder such as a hall-effect   switch. I am not the one to advise you further but someone may even know the way to program the board to read the dialler or maybe rig an actual hall-effect switch to the dialler's shaft.  My knowledge of that type of thing is limited to the application of Difference Engines designed specifically for the Autokinetica.

Wood cladding for the sides







If anyone is wondering the brass strips are off a piece of restaurant furniture, they are the strips to slide your tray across at the counter.
