[neonixie-l] Re: mason jar numitrons

[Mark Moulding]

I built some huge fake "Nixie" tubes for a Burning Man project using empty 
two-liter plastic soda-pop bottles, with the digits formed using EL 
(electro-luminescent) wire.  EL wire need about 100 volts or so, but AC at 
around 1 kHz.  The frequency can be critical to get good brightness, and 
also significantly affects the life (although this was only for a two-week 
project, so I didn't care much).

I ended up making a software-controlled inverter power supply, then using 
sensitive-gate high-voltage SCRs to switch the excitation voltage to the 
various digits.  They looked great at night (but were invisible in daylight 
- a fundamental problem with EL wire).  The trickiest part was threading 
the digits (which were supported on coat-hanger wire) through the necks of 
the bottles; I cheated a bit by cutting a slit on the back side.

I hope I misunderstood, but elitist attitude?? That's a bit harsh regarding 
what I said. I did finish my 'rant' with the statement each to his / her own. I 
meant that. I did nothing more than voice a point of view without personal 
judgement. Why go there?

I had recently one of my projects (a numitron clock) featured in Nuts & Volts:

 

http://www.nutsvolts.com/magazine/article/September2016_Numitron-LED-Clock

 

this project was entirely done in assembly.

Sorry, my choice of the word hate was intended to be somewhat tongue-in-cheek.  
 I'm relatively tech agnostic in terms of projects, although as a relative

Atmel tech.  In the past though, I've done stuff on the Arduino, and then

haven't actually done of my own PCBs yet though, so I'm still a piker.

 

Hats off for your use of assembly, I haven't done any assembly since my

I generally agree on the 'good old stuff', but I make an exception for the 
wireless Raspberry Pi. You literally get a full-blown Linux environment 
that; put inside the case and never need to plug-in a cable, or open it up 
to make enhancements. Just login remotely, recompile, and reboot. You dont 
even need to set the time; it's automatic (as long as  internet service is 
alive..)

I do plan to retrofit 2 of my other clocks currently with FPGA's to run on 
Pi's.someday

 It's not so much the Arduino ( though I don't have a lot of time for that, 
especially when it's the
first word of a project description), but the that you have this nice display 
with an ugly fat cable
going in to an ugly box.

> I realize the Arduino makes an easy target, but why the hate?

 

Ah, I’ll go out on a limb (BTW, “hate” is probably a bit strong), but from my 
perspective it’s an old phart thing. The Arduino is so hyped up, it reminds me 
of Harley Davidson motorcycle owners. They seem to think theirs is the only 
one, the best, nearing cult status. On FleaBay they even advertise things like 
capacitors as “for Arduino” just to get the hits. Yes, I’m an old phart, and I 
still like to do things the hard way. To me, building a project is, or at least 
should be, more than plugging in shields and loading prepared libraries. I like 
to understand what I build, and put it all together myself. I still use 
assembly language for smaller projects. Since the nixie community is very much 
about old technology I assume there are probably a few more who feel that way.

 

But each to his / her own……..

I checked FleaBay, and I saw a lot of them advertised as 12V, 1W. 5 of them for 
around $2. Not too bad, worth ordering a few to play with.

Yes - you can run them at lower currents - you may start to get less uniform 
brightness at some point, but you could PWM them

Typical spec is 55-60v forward voltage,. max current 10-15mA

I suppose dimming would be done as with any LED, preferably by means of PWM?

I did play with these about 3 years ago, since then shorter filament strips 
have become available for half-segments.
