Re: [neonixie-l] Re: Nixie driver problem when going over 170 VDC
Hi All, thanks all for this valuable comments. I see now that I should have studiedt more before creating the PCB. I really thought its just wiring the things together! I see that the arduinix layout is much cleaner, but does it fullfill all the arguments from Alex? I will take all this input in my version 2.

As others have said, your PC board layout may be correct for your net list, but it is completely wrong for a switching power supply. The Nixie power supply design by Nick DeSmith is a good one. Copy it exactly. When doing a PC board layout, the first thing to do is to move around all the parts so that the connecting lines are as short as possible. This takes a lot of time. I will typically spend a day moving the parts around to get a nice placement. After I do that, then the wiring part of the job only takes an hour. Also, be sure to use heavy traces for power. Those bypass capacitors next to the ICs are essential too. A PC board layout that looks pretty is more likely to work well than one with the traces spread nilly-willy all over the board. https://lh4.googleusercontent.com/-PsF8r0jvHEQ/UZDN7eiidtI/BH4/x_mkJRi4IPU/s1600/nixieclock_v1.1_Leiterplatte.jpg -- David Forbes, Tucson AZ -- You received this message because you are subscribed to the Google Groups neonixie-l group.

I have an other scematic, simulatet and it works in hardware. http://threeneurons.wordpress.com/nixie-power-supply/ Jens Am 15.05.2013 08:47, schrieb nix: Hi All, thanks all for this valuable comments.

[neonixie-l] Numitrons spotted?

[neonixie-l] Steampunk Spinner on eBay
Interesting to see if it goes anywhere: http://www.ebay.com/itm/140976925149 It's not my listing, and I'd say I have nothing to do with it, but I suspect I sold him the spinner kit, its based on. -- You received this message because you are subscribed to the Google Groups neonixie-l group.

Yes, Numitrons. In the USA, we had Panaplex displays in our gas pumps for many years. I spotted a couple the other day in a derelict station on a winding mountain road. I didn't pull over to extract them, though I imagine I could have. -- David Forbes, Tucson, AZ -- You received this message because you are subscribed to the Google Groups neonixie-l group.

I vaguely remember numitrons on gas pumps. I definitely remember 7-segment neon panaplex-like displays being used. They had those at the gas station I regularly used, for a couple of years.

[neonixie-l] Re: Numitrons spotted?
Theres a station out in the country not far from here that has the same pumps, they are made by gilbarco, and there are still some pumps with nixies in in this country. Magnetic flip 7 segments still sem to be the norm here, lcd's are creeping in slowly.
