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