Why should the minus sign be on the right?
There's no rule that says the numbers have to allign to the right side of
the display. Why not allign them to the left?
So instead of displaying -..1234 make it display -1234..
(the dots represent non lit tubes).

I found that single custom key caps are very expensive. Since I made only a
few of these calculators, I ordered complete sets with 104 custom key caps
(for an entire keyboard) at WASD.
The problem with that, is that these keys have different shapes (row 1-4)
and sizes.

Hello, I have been thinking about having a stab at a nixie calculator
myself! My stumbling block was the keys (specifically, the key caps). What
is your source for these?

Prusaslicer has a feature called ironing. After a little bid of sanding the
PLA top surfaces look quite ok.
There are also some pcb manufacturers that offer 3D printing with
interesting prices and nice finish.

I made the project available on github, but there is no way to build it. I
used the AP63203WU-7 and AP63205WU-7 voltage regulators. They were new,
cheap, easy to solder, and widely available. Now you have to wait until
March 2023 to get one, just insane ...

In case anyone is still interested, there is some work in progress to make
the project (IN-16 and IN-17 versions) available on github.
The original project was not suitable for sharing for various reasons. I’
currently assembling two new calculators to test the changes I have made to
improve
I’m cleaning up the firmware of the calculator and I have moved the code
for the calculations to a small separate library.
Actually, I would like to learn how to build unit tests and that’s the
ideal type of library to start with.
But I quickly found out that this is boring and not fun… so, no
I just spotted this one:
https://www.ikea.com/us/en/p/duktig-toy-cash-register-80256501/ maybe it
could be used as a base for those who want to build a calculator with fewer
digits?
I do not know what it looks like inside but it seems to be space enough for
the electronics.

The number of digits was determined by the maximum print area of my 3D
printer.
The software is still in progress, there are some features I would like to
add:
- switch between radians and degrees
- fixed decimals mode, right now there is only a floating mode
- padding mode with leading zeroes
I've just re-read this thread and really like the way that this project has
developed. I think I need to make one at some point. I have no idea how one
might go about programming a calculator but would love to find out about
it. I'm guessing that it took a bit longer than the 2hrs you'd

That's really cool! I have wanted to make a Nixie tube version of an HP-11
for years, but got stuck on the keyboard.
I have a box of +- tubes if you're interested.

No plans at all, sorry. I don't share or sell because I don't want to deal
with open hardware licenses and liability issues. Perhaps one day one of
the engineers on this forum may decide to create a professionally designed
calculator kit. I have no idea if there is a demand for such a kit,

Currently working on the B-5870 version, all digits and decimal points work
fine. I really like these nixies…
Any recommendation for the anode resistor value (170V)?
In the datasheet the anode resistor value is 7.5k, so I’m
This is the finished IN-16 version. I'll add some more clock modes with
date and some animations with the decimal points. That’s it!

For the keyboard I’m using a HT16K33 in a 3 x 9 matrix
The display board uses 5 cascaded HV5622 shift registers. Since the IN-17
has no dot, I had to use 3mm
These are some of the keycaps for the 'extended edition'... just kidding :-)

Thanks for your input, Richard. I don’t have access to a CNC device right
now, but such a router is on the top of my (maker) wish list.
I have found a place where you can define the text and color (no graphics)
of every keycap for an entire keyboard. So, basically you get 104 custom
keycaps
Many Many years ago (1980 ish) I was involved in what were known at the
time as Microcomputer Terminals. These were Z80 based machines running CP/M
which used serial Terminals (VDU's) for I/O. We created some software which
required custom key caps so I (as the junior!) was sent off with a bag
Made some progress with the case but I don't like the keyboard at all. I
designed a new keyboard with the standard functions. Any source for custom
keycaps that you can recommend?
Not sure about the acrylic for the display, maybe brown or gray...
