Here's some video of the Dekatron and the tubes I took at the weekend.

Analogue

It's push for analog!

Nice link, I was actually taught from that AP (Air Publication). I did like the old analogue stuff. ICs left me cold.

My favorite circuit of all time is the pentode phantastron, found in many old radars. I particularly like the fact that you can only fully explain how it works by using -ve to +ve (actual electron flow) rather than the conventional +ve to -ve.

My grandfather gave me a physics book from his schooldays and it did state that electrickery went from -ve to +ve.

I didn't think that was going to help me pass any exams, so politely ignored the rest of the book.

Goodness me, I thought I was the only person who found that sort of thing interesting.

They are pretty aren't they?

I've got a ratemeter with some in & it's gorgeous

Ooooo.

The tubes spin?

That's novel.

ok so the tubes don't spin, the little glowing light does. Smart arse.

You'm trailing parenthesis is outside the [/url] thingie, old chap.

Wtf?

It's a conspiracy

I reported that bug to vBulettin ages ago

I saw the Witch Dekatron at the Computer Museum this weekend. That's a nice early computer with those wonderful clicking noises and spinning dekatron tubes.

What?
