ThermoNixie - the making

For as long as I can remember, I have loved nixie tubes. I asked my father the other day and he said that I was fascinated with them as a child. About 6 months ago I found some neat nixie modules on eBay (from former Soviet Union). The module includes a nixie tube (0-9 digits), a binary decoder chip, and they are stackable. I bought several and they sat for a while.


I knew I would have some extra time over the holidays and planned to get this idea moving forward. I purchased a small power supply that buck-boosts 9-12V to 200V as this is needed to power the tubes.

So I wired one up...

Vid linky

Some people make clocks, I wanted to make a temp display. I knew of various special character tubes (deg C, Hz, omega, etc); I ordered a few of those as well. I had to de-soldier a digit display tube and install the special character tube (to display the degC character). Then I decided to include a leading + or - sign, I had to order a different special character tube and repeat the de-solder/tube swap scenario.


I prototyped using an Arduino however I am now using a stand alone micro-processor with a temperature sensor. I wrote an averaging algorithm to damped the change rate. This "averaged" data is shifted for proper display and sent to a couple of registers. Once the registers are full, the data is sent to the nixie tube modules. The included decoders covert the incoming binary numbers and light the proper segments.

My components are still on breadboards.


I am in the process of designing component placement and I will properly mount a single circuit board. The outer cover is from an old Apple ][ floppy drive I built the inner tray using a bandsaw, dremel and a brake. Still thinking about painting that portion.



I am thinking about future expansion. Mainly mating a temperature sensor with a driveway solar light (for power) and using a small Xbee radio transceiver to periodically send outside temp data to this box (I will have to add an Xbee to this box as well to receive).

I used some of the material given to me to do this:


Raw stock from a generous Kirk!








Going to replace this crap rack and fit this space.

Some of the WORST welds I have ever seen, but they should hold for my application.

I plan on adding a shelf for the fridge, and another on top to put my assorted nuts and bolts. The left is open for the compressor, and on the right will go my SS tool box on the bottom.

Izzat galvanized or are we welding with a flux core wire feed?

Both! I ground off the galvanized parts, and welded outside in a breeze, plus I held my breath and stepped back after each pass to avoid breathing in the fumes.

Still, flux core welding, and lack of experience, makes for some ugly welds. The only good looking welds didn't have much penetration.

Just amazing...i always love the clocks...never see before the temperature sensor...;)

Can you give me some lighs on this...i mean...in material...how much can cost to make a small clock for my desk? do you have any idea?

Nixie tube clock kits are available on eBay an the internet. Generally a kit will run about $100 and normally do not include the tubes. 4-6 tubes from Russia or Ukraine will probably be another $25. Soldering can be a bit of a pain without prior skill or a good soldering station.

Did you notice the engine valves for axle/wheels?

I can't wait to post the finished product! That one is already sold.
