And it's sold already. I wonder who if it was someone from here?

Probably - Pete knows about this thread as we've been exchanging emails today

Ive followed the instructions shown but when i test for 170v between ground I only get 12v. Playing with the dial doesnt change the voltage as well, any ideas?

I felt the need to melt some solder this evening so I've just started. I won't be taking pictures of every joint but here's the first three components in place.
Sam, I've not looked at the circuit diagram yet so I've no idea what point you're at. If you can't suss it, I'd suggest emailing Pete ([email protected]) as it's probably something staightforward.

Check for short circuits, make sure that you've soldered all the dioes in the right direction (they only go one way) and make sure that the LM7805 and IRF630's are the right way round.
Also, did you forget to insert the microprocessor and/or is it correctly soldered in place?

I'm definitely going to give this a go. Looks like fun 
. Will be good practise as well.

Muppet award for me........................Didn't insert the micro-processor
Doh!
Doh!

It's a slower procedure than I expected, some of those pads around the resistors are indeed very small as are the ones around the two bugs.
Anyway, I've got the PSU stage built, tested and set up to 169 volts and now I'm off to bed. I should be able to do some more tomorrow and then that'll be it until the weekend.
/edit - Sam, doh!

Feek, i know it's only three diodes (well, it was when i first wrote this 
), but that soldering looks pretty much perfect
Would it be worth having an '****Official Electronics Thread****', do you think? There's certainly been a lot of interest in this one project alone... i've got the beginnings of a new project in my head - a switchable AM/FM/SSB radio. Potentially with an alarm. Should get me back into the swing. Can't find much on simple radios (after a very quick look) - a lot seem to just be extensions on the MK484 which i can't help but feel is cheating a bit.
"How to make a radio:
Step one: Buy a radio
Step two: ???"
We'll see how it goes

I love the look of these, I really want to make 1, there's a few here which look amazing, expensive, but so worth it:

Not sure i like the LEDs at the bottom of the tubes tbh, kind of detracts from the whole point of having nixies in the first place
Soldato
That's true, I see what you mean, I just kinda like the glass look with them sitting on top, able to see the electronics through it.
I wonder if you could do these but take away the LEDs from the circuit and replace them or just simply bridge over the connection gap with a wire and by-pass having them at all.

It would probably be easier (and cheaper) to use a completely different kit and just design your own enclosure for it
Soldato
I'll have a shop around and see if there's 1 similar to that enclosure, really like that 1.

I recon an official electronics thread would be a good place to start. I would still be going now if I didn't take my soldering iron run out of gas to go bed. Who knows maybe the thread would get so popular a sub forum may be needed?
we could just rename this thread "*** Official Electronics Stuff Thread ***"?
Hehehehe, at least it was the very very simplest problem to rectify
Looking Good Mr Feek
