Hello everyone!

 

I’m new to this group and this is my first post.

I’m looking forward to design & build a particular project with Nixie 
display, but since I’m really not an expert and just starting, I would very 
much appreciate your help & feedback. I do have some specific questions (in 
the end), but if you look at project goal & design principles and think of 
better way to do things – please comment as well!

 

*Project goals:*

A Raspberry PI controlled Nixie display, with some additional LED 
indicators for weather conditions. Nixie display will be used to display 
the time or temperature or humidity, depending on settings.

Main assumptions:

1. 6 lamps: IN-19V ("+"/"-"), 4 x IN-14 ("0" - "9" + 2 dots), IN-19A 
("C"/"%") 

2. Ability to control Nixie brightness (by Raspberry PI) 

3. LED RGB back-light under each tube, with color & brightness controlled 
(by Raspberry PI)


The look I want to achieve:


 

*Design principles:*

1. As much as possible – use the components available on the market. I’d 
like to avoid designing PCBs, avoid designing custom circuits, minimize 
soldering, etc. I understand I’ll have to do those things to some extent, 
but being a newbie, I want to minimize room for failure or issues. 

2. A single visible power supply for the whole thing, from 230V AC outlet, 
driving all 6 nixies (180V, 30mA), Raspberry (5V, 3A) and the LEDs.

3. All components should be ideally driven by Raspberry I2C bus interface, 
using which I could control separately: displayed value of each tube, 
brightness of each tube, color & brightness of each LED. I think this is 
the easiest and most versatile approach (but again – looking for 
confirmation / other suggestions)

 

*Questions to start with:*

1. Are there any available to be purchased components, which you could 
recommend, fulfilling above design principles & goals? Right now, I have 
the Raspberry & the tubes, but nothing “in between” J

2. Do you think my idea of controlling all components via I2C bus is a good 
idea? I want to go for the easiest and most versatile approach.

3. Are there anywhere existing sockets for IN-14 / IN-19 tubes? Or will I 
have to solder to tubes to whatever components I select?

 

Thanks a lot for your help!
