 All electrostatic demonstrations require a cat and a Perspex rod.
Two:
 See how my knuckles are not crushed ?
Three:
 Well, duh.
Four:
 Need a bit more imagination than the other three.

Only a week behind with my posting. Relatively punctual.

Donna had a conference in Lisbon to go to. I had the painful duty of carrying the suitcases and amusing myself in the city for a few days.
I took a few ( pictures. )

This is only medium-well planished. But, camping next week, shame not to take a spork...
10g of 0.6mm Ti sheet, hammers. Fork tines came out a little graceless, but close enough for jazz.

All my forays into engraving have been rather troublesome, using push gravers or hammer & chisel.
A couple of weeks ago, I got myself a Magnagraver , and that has transformed the process. At least, the process of making lines is easier. Making the lines look like anything in particular is obviously still hard.
Anyhow, here is my first testpiece, on a bit of 15mm wide mild steel. As you can see, it is a traditional hunting scene:

Last week included a trip to the Computer History Museum in Mountain View, California. They have many fabulous things, and I suggest you all go there at once.
Here are a few highlights, from Babbage to Google:

I have, therefore, waxed my coat.
That should fool it.

This time, using a peroxide browning process on the steel:

More details here. I think I over-planished this one a bit, so the silver looks squishy. Must try harder.

These each held thirty gigabytes, before I got at them with my hammers:


Suprisingly stretchy stuff. The coating is much more durable than I was expecting, too. Nothing fell off or went flaky.

Here's my Saturday afternoon experiment, sticking silver to steel by the nunome-zogan process:

More pictures, and a bit of a writeup, are here: http://www.jarkman.co.uk/catalog/jewel/nunome.htm.
I'm frankly amazed that this process works as well as it does when done as badly as this. Now I just need to work out what to make with it that isn't just a test...

Dorkbot Bristol had a hat-hacking contest yesterday.
There was much entertainment of the usual sort, technical chitchat and swearing at computers, and a bit of actual constructional work. I made (well, half-made) a computerised hat with a compass sensor. None of the work was really very technical, just a lot of fiddly wiring-up of stuff.
It's kind-of finished now, and the full writeup is here, for those of you that enjoy masses of tangled wires: http://jarkman.co.uk/catalog/fripperies/compasshat.htm

Obviously, I am in favour. But still perplexed.

Yesterday, we played with the BronzClay(tm) that I gave D for Christmas. And today we fired it, with suprisingly good results (click for the album):
Working with it really is like working with ill-tempered Plasticine. You can squish it & roll it & generally shove it about, and then suddenly it is too dry and cracks in two. It was made to be worked by the swamp-men of Venus, with their steamy atmosphere and glabrous fingers. But humans can manage if they are persistent.
The astute reader will spot the textures of ray-skin and sea-urchin and machined Perspex in some of these pieces. Oh, and the shiny things are 5mm steel ball bearings which were fired in.
Firing is a bit long-winded - bury in charcoal, ramp at 250C/hour to 840C, hold for 2 hours, then cool. These bits have all been tumbled for half an hour to burnish up the surface a bit.

Well, we've spent most of the time since Christmas in bed, and not in a good way. As the upstairs heating broke on Christmas Eve, staying in bed has required two duvets and the occasional hat.
But the pall of plague is starting to dissipate now, and normal life is slowly resuming. By way of celebration, here's some of our festive manufacturing to feast your eyes on:

It's a B&B in a lighthouse with a Dalek. Who could ask for more ?
