[neonixie-l] Nixie Clocks

2016-07-12 Thread Roddy Scott
Hi Folks and thanks for inclusion into the group! I got started with Nixie tubes when I built a large Steam Punk lamp for my daughter's birthday last year and it looked kind of lacking in the middle, that is when I discovered nixie tubes. I added a little IN-12A kit to it and I have been hooked

Dalibor, As an expert on the materials used in the manufacture of nixie tubes, would you recommend any method of cleaning or neutralizing the corrosion of the pins and seals? Is there any chemical that could neutralize the chemical reaction of the pins which would slow down the proces

Thought y'all might be interested in my conversion of a 1971 Singer/Friden EC1117 nixie tube calculator into an Android controlled date/time clock with arbitrary digit display. This will probably make more sense after watching a demo of it in operation here: https://www.youtube.com/watch?v=mib

It is possible, the cathodes are usually stainless steel and they do not get poissoned on air. Once the stack is mounted and sealed in new tube, it is necessary to do ageing procedure again.. Dalibor 2016-07-12 21:16 GMT+02:00 Charles MacDonald : > On 16-07-12 02:13 PM, Dalibor Farný wrote: >> >>

Hey, I just bought the Blue Dream and fully assembled it. I've ran through all the soldering points and they appear to be ok. But when I plug it in, nothing happens. There doesn't seem to be any trouble shooting guides or help of the like so I turned here. Anyone have a good suggestion where to

Hi Jeff, I guess it is a leak along one of the pins, dumet seals can corrode (it is a copper plated nickel-iron wire). I would be interested to do a leak test on a helium leak detector. Of course if you can miss the tube. Just a very small (tiny tiny!) amount of air is enough to ruin the balanc
