After the success of my first nixie clock made out from a rosewood block, I decided to lose no time and to carry on with the next one.
As some of you guys already know, or imagine, lately I'm indeed a little bit addicted to nixie-mania.
I've bought many nixie tubes on eBay, and I experienced in electronics so to build my own high voltage power supply and then the ultimate nixie clock circuit.
Digits for this clock are nice rounded and fully transparent IN-4 tubes, the same I used in the first model, but as I previously announced, I aligned them vertically, so to read from top to bottom hours, minutes, and seconds. Indeed you will see the undeniable influence of Max Pierson's vertical clock.
I guide you now through the full process to make your own unique nixie clock.

WARNING: this circuit raises the voltage to deadly 300V so you must avoid to touch contacts while working, I'm not kidding, please BE CAREFUL!

Step 1: the case and start point

Although I was looking for a nice wood case to use as clock case, when I found this ancient wood handrail piece I suddenly pictured the awesome nixie clock it would become.
I didn't have the camera with me, and I drilled the handrail at once, so I can't show you the intact piece. I used 30mm drill bits as for the previous clock, then I cured the wood with woodworm poison since there were some holes in it.

<p>Love vintage approach. I recently made a binary clock from an old (circa 1948) Speed Graphic large formate camera. Turned it into a projector by placing led binary clock in back at film plan. Projected image is redirected by mirror at 45 degrees to optical access onto moderately etched glass. Sorry it's upside down.</p>
very nice! I love it!
<p>I was wondering what the cabinet is on Step 20. The on with the 10 drawer chest. Much appreciate your time and effort in these instructable.</p>
oh, it's the wardrobe I've put in the livingroom, it has 60 drawers in total and they're very convenient to keep project stuff and tools ;)<br>it was made originally for a shirts and neckties shop in Milan Gallery
<p>How to programmer RTC ??</p>
<p>Really m8, that is pure art! :D<br>Congrats on the design and how it all worked out! <br>Really unique and amazing! Bravo!!!</p>
grazie! troppo buono! ;)
<p>You can hang on cable a weight and warm up a little by hair dryer. Then let it to cool down.</p>
nice thought!
<p>this is beautiful.</p>
thanks!!
<p>I love this design, now I know what I'll be doing this weekend, thanks for sharing!</p>
all in one weekend? :-O <br>did you make it? ;-)
<p>Is there a full B.O.M. ?</p>
it's the same of my first nixie clock, plus diode D5<br><br>PS: I made another nixie clock, the huge one, go to read that instructable too, which is the newest one. a fourth clock is on the way
<p>make the cable straight by attaching a thin wire to it.</p>
Gorgeous!
<p>thanks!</p>
<p>congrats, never seen before clock like this, i wish that witch clock!</p>
<p>thanks! I'm planning to make some kit if someone needs it :)</p>
<p>This is awesome. Have you sold this anywhere like eBay? I noticed that the power brick was euro. Have you made an American (120 Vac) version?</p>
Thanks! I still have my nixie clocks, I'm planning to sell them in future.<br>I live in Europe and I don't need a 120V power brick PSU, but the modifying process is the same.
<p>This is brilliant :), Vote For you :)</p>
<p>Thanks!</p>
<p>I am so glad you won :), Congratulations !!!</p>
<p>And I'm so glad you liked my project :-)</p>
<p> <br> <br></p><p class="MsoNormal">Hi andrea biffi</p> <br> <br><p class="MsoNormal"> </p> <br> <br><p class="MsoNormal">This nixie clock looks really fantastic, puristic in its <br>design with clear lines and the classical form oft this ancient handraill. <br>Nothing disturbs the view to the fascinating nixie tubes counting the time. <br>It&acute;s your style!!!</p> <br> <br><p class="MsoNormal"> </p> <br> <br><p class="MsoNormal">Especially the vertical &bdquo;position of time&ldquo; seems to be a <br>symbol of a &bdquo;countdown&ldquo; of life. Absolutely great!!!!</p> <br> <br><p class="MsoNormal"> </p> <br> <br><p class="MsoNormal">I am deeply impressed about this harmonic arrangement an the <br>wish to build also a vertical nixie clock rises inside me........</p><p style="margin-top: 0.0px;margin-right: 0.0px;margin-bottom: 10.0px;margin-left: 0.0px;font-family: Arial , Helvetica , Verdana , Tahoma , sans-serif;font-size: 15.0px;border-right-style: none;border-bottom-style: none;border-left-style: none;background-image: none;">Five stars for the idea, the documentation, the brilliant workout and I am convinced that you are already a winner with this project (voted;-))<span class="Apple-style-span" style="display: inline;float: none;"> </span></p> <br> <br><p class="MsoNormal">Take a bow</p> <br> <br><p class="MsoNormal">Yours Aeon Junophor</p> <br> <br><p class="MsoNormal"> </p> <br> <br> <br> <br><p class="MsoNormal"> </p> <br> <br>
<p>Dear Aeon,</p><p>I'm really happy that this clock came out so harmonic. Next one will probably be more steampunk style!</p>
<p>*cough cough* I think I may have caught your Nixie-mania bug. I'd love to make one that displays a full GPS string, but that is well beyond my skill at the moment, so I'm hoping to learn from your projects. Thanks!</p>
<p>ouch, there is only one solution to recover health, just make the more nixie displays you can!</p>
<p>Yay! Its fixed :D Awesome project Andrea. Well documented! (subbed) and voted! :-)</p><p>Now lets hope you become a finalist! X (fingers crossed ;-))</p>
<p>tThanks hunter!!</p>
<p>No problem! You did a awesome job! :D</p>
just awesome!
<p>Awesome job! The case is so beautiful!</p>
<p>I still have so much to learn (from your projects too!)</p>
<p>It is so beautiful! Voted :) </p>
<p>:-) too kind</p>
<p>To straighten the cord you could try stretching it taut for a day or two, or folding a cloth over it and ironing it.</p>
<p>I will try the ironing, thanks!</p>
<p>Love those nixie tubes!</p>
<p>me too! ...did you already understand that? ;-)</p>
<p>This is so so beautiful! Great work as always :D</p>
<p>Thanks Jessy! such comment makes me proud :D</p>
<p>Wow this is really impressively documented! Just wondering but what is that really cool tool on the first picture of step 17? Is it just a fancy looking screw driver?</p>
<p>That tool is a gimlet, and it is used for starting holes for screws ,or making holes in thin materials.</p>
<p>Ahhhh! I think i've seen those around before, thanks!</p>
