The True Meaning of Christmas
Sadly, as far as I am concerned, the church has this 180 degrees out of phase.
The true meaning of Christmas is not about baby Jesus, it's about parties, presents and celebration. In fact most people have got Christmas just about right when it comes down to it. It's the church, which hijacked a pagan festival, developed its own white lies around the festival and has to repaint it each year in an attempt to keep the facade up that has got it wrong. Even "Bible-Believing" churches can happily stand on their heads for the festive season; pointing out even simple falsehoods wins no prizes as a myriad of excuses for continuing the tradition come to the fore.

The shape of an electric field.
I got the slab like plastic piece in picture one from a charity shop. It's the base unit from a plasma ball and inside it has a battery powered high voltage, high frequency generator. Bit like a small tesla coil - although as far as I can see it's pretty much solid state. Any coils are hidden in a block of epoxy resin inside.I got it to try to make the violet ray work - which it did after a fashion and yesterday had a thought and wondered if it would make a small neon bulb glow as well. It does, quite nicely. The neon isn't attached to anything, although if you touch the wires the bulb glows brighter. In fact, if you touch the wires lightly you get a small arc of electricity in-between your finger and the wire which burns small holes in your skin.
I then was showing this to a friend who asked how far away it worked, and thoughts turned to plotting the effective range. These photos are the outcome of that thinking. The block is switched on in almost total darkness. The camera is set for 90 seconds (total) exposure and the neon bulb is waved around in the air above the block. What is revealed (unsurprisingly really) is a dome shaped field of energy above the block. I also measured the voltage from the neon's wire: 320 vac.
I'm going to use these bulbs as eyes in my bug sculptures. They also light up quite happily from static electricity. 150 are arriving tomorrow from an electronics wholesaler!

Edwardian Daleks
I find the resemblance between the automatic soldiers in the trenches and Daleks uncanny. I only wish I could actually get hold of a copy (Yes, I know I can pay large sums of money to some US citizen.) and see the detail in the drawing. The jpeg below that I found in several places on the web simply isn't detailed enough. The body shape, in particular the head and the cable/piping around the head particularly resonate Terry Nation's creation. I was reminded of the appearance of the Dalek in the last season with Winston Churchill.
Interestingly in this picture the armaments appear to be machine guns. I realise that this was hot technology at the time, but in other articles in the magazine a death ray either produced electrically or from radium is proposed. In fact there's another cover with walking tanks using radium dearth rays published a few months before hand.
Electrical Experimenter has been a fruitful source of both practical early circuits and edwardian speculative articles. If you look at the early editions they are grounded pretty much in fact, but as the magazine progresses it slips more and more towards speculation. Nevertheless, it's an eye-opening window into what the future was supposed to look like nearly a hundred years ago, and unlike many similar publications, the predictions are closer to what actually happened in some cases.

Thoughts on print buying.
Having said that I don't always use the cheapest printer and I don't spend hours shopping around. I tend to use people that I've had consistent good results from and from who I know I'll get a good result. Also I want as much automation as possible, I want to be able to upload files and get them in the print queue as soon as they are ready to go. I want the process to be predictable and repeatable. And I want guaranteed turnarounds.
*one of them lives here: http://www.printbydesign.co.uk/, and no, they haven't paid for this ad, nor are they expecting it to appear.
