I uploaded a version of the russian-nixies.lbr (Eagle footprint library) here 
that has a corrected footprint. I added a footprint with pads for the female 
D-SUB pins that many folk seem to use as sockets. I'll add KiCAD files when I 
figure out how best to get them from the Eagle files!

By the way, does anyone have CAD files for the physical pin layout? e.g DXF

Re: [neonixie-l] Re: Mounting IN-18 tubes

2017-02-08 Thread Roddy Scott 
They are approximately 2mm thick. Laser cut, film covered, you need to push 
out the waste from the pin receptacles on them before inserting the pins. 

I have the Spectrum 1040 kit variation for Z568M tubes. Pete has a few 
different tube mounts for the Spectrum kit depending on which tube you are 
using.

Contact Pete and he should be able to supply the Plexiglass base parts for 
the IN-18 tubes.

If you wanted to make remote 'sockets' from them you could solder wires to 
the pins before mounting them and make a small dam around the plexiglass 
with tape and flood it with a little 2 part epoxy keeping the socket part 
of the pins clear of the epoxy. Then you would just need to put heat shrink 
on the connections.

Thanks. I ordered some pins.

Can anyone tell me the thickness of the acrylic disks that PV electronics use? 
I am about to order some acrylic pieces for something else so it would be good 
to get a few disk prototypes made.

I use socket pins soldered into the PCB. Yes, there's also a hole in the 
PCB for the nib.
The socket pins are low-insertion force, so it's very easy to remove the 
tube if necessary
0. Carefully bend any obviously misaligned pns. Be careful because the pins 
are very soft. Ignore the surface corrosion.
1.  Individually number each tube, and assign it to a specific PCB location
2. Insert socket pins onto the tube
3. Solder tube onto PCB. The socket pins are formed to the tube and that 
will minimize stress as long as the pins are not bent later on.
4. Remove the tube and carefully set aside.

After you're done, carefully insert the first tube, power-on, test, etc. 
Then insert remaining tubes

Lastly, a 3D printed collar is a nice final touch. It enhances the 
appearance, makes it slightly easier to insert tubes, and protects the 
socket pins from bending.

I was worried about that, too, when I made my latest clock



The socket scheme for the IN-18s is covered at my Improvised Socket 

 
page.


There are holes in the base, below those tubes, that match the tube pin 
arrangement, including nipple. But they are drilled well over sized to 
allow the sleeved socket pins pass thru, with no friction. The pins float, 
and there is just the slightest amount of friction against the base. A tube 
will, however, pull out, with only a few ounces of force. This does mean, 
that you have wire a large wiring harness.
