Just add an LM7809 voltage regulator, which will drop your voltage to 9V from any source between 12 and 35V. I think that the circuit doesn't work directly with 12V...

Un not sure, but in my opinion you can give a try. Actually it's pulsing current, maybe it will work..

Awesome! Thanks for your contribution!

Ouch i have no idea... I hope members will help you with this. It will be useful!

I'm not sure what you mean with "paper foam"... But it appears you can replace the entire gasket with not many problems, you just need the right size.

It's beautiful, well done! 👌

I'm happy you made it! Well done! This is a very good PSU!I'm not sure why your doesn't shut off... it should.Bye!!

Very good! 👌

IMHO the C shape is absolutely necessary 🙃I'm so happy you made it!!

this project is so useful for schools... I'll make it with my students, thanks!

Those circuits are awesome useful, but i suggest to follow instructions on their original website http://www.talkingelectronics.com/projects/50%20-%20555%20Circuits/50%20-%20555%20Circuits.html You'll find all informations there. This is not an instructable, as the author say it's only wasted time ;-)

thanks!

Dear Duncan, sorry for late answer. I'm really interested in your project, that will be cool. Cad drawings are attached to step 6, I think you could use those drawings. There will be no problem in sawing pieces with jigsaw. Let me know if I could help more.

I'm happy it's useful to you!

Hello Kjetil, I just realized it's you the first guy which congratulated with me about my first at all nixie project! 😀 Wow 6 years ago... That's great!

I remember that few years ago every project became a central topic for many members. Although staff was very active, I think that biggest part was made by the community itself, I feel that I myself reduced my involvement in community, and I try only to answer with decent time to comments on my ibles. But I know that it's not enough and I would like to extend this appeal to all community members (not to you who never stopped to be very participant and active).I built a pair of great friendship thanks to instructables community, and I know it has a good potential to connect makers and people across the world, but everyone of us has to work on that, and of course staff should provide a solid structure on the website which will help a lot. I promise that I will try to help as I could, start...

I promise that I will try to help as I could, starting with showing a picture of Aeon Junophor and myself discussing about how to rebuild instructables community ;-)

Sorry I was more active in Instructables community before, actually this teaching job hadn't left too much spare time to chat here. Anyway I'm teaching in Waldorf highschools, physics and technology.

It's strange, maybe some component heats up, or maybe there is a power loss... Try with a more powerful PSU, maybe 12V 1A. If that doesn't work you should look to some heat, but only on the low voltage part of the circuit, don't touch the high-voltage part!

Beautiful art, as always! Congrats!

I really love creations and gadgets from scraps as much I hate plastic toys and tools which pollute our planet!

I understand the need to compress images on the instructable page, anyway I agree with you that a better quality should be welcome, especially for diagrams. It happened that many people asked me to send bigger diagrams because they couldn't read numbers, nowadays some of them are used to have everything ready and they didn't click on the thumbnail to obtain the full res image.

I mean slice a cake... you can use a cutter, so to engrave a groove, maybe on both sides, then bending the CD you can brake it along the line.

My dear,it seems that you didn't get the aura of simplicity which blows gently around this project, but believe me, it's much more simple than you could think. Just make it, with toilet paper tube and the worst audio CD you still own, only your fingers to make the slot... No 3d printed parts, no prints, no technology and no concern at all, it will work great!

Your links are awesome! I still cannot believe there is so many people every day in the world examining light spectrum!

Thanks Aeon! You're projects rock too! 👌

Thanks Aeon! You're projects rock too! 👌

It's there!

Yes! It's really awesome! And kids love this too, they could learn amazing topics with very easy diy stuff! :-)I'm actually holding physics classes in Waldorf high-schools, and these projects are an essential part of teaching!

You're right... I couldn't take a good picture but today I will add a sketch!

Thanks Jessy, it's a tool set I built for my optics physics class, we observed many different lamps, it was great.

Thanks that will be super-useful!

It's beautiful Aeon! Well done!

And less than 2A...

It's strange... my only supposing is that your psu doesn't really give 3A, but less than that when there is a load.

It's awesome! And much larger than a Nixie clock! If you want to build a Nixie clock, I made some one ibles about that, you'll see that it's not expensive and difficult as you believe ;-)

Look at my ibles for making a Nixie clock. I love the in-4 tubes which are not more expensive than 4-5 $ each.. but you can buy cheaper very nice tubes for 2$ each... And you can learn to make yourself the PCB with not much money..

Start from here with only one Nixie tube:https://www.instructables.com/id/High-Voltage-Power-Supply-for-Nixie-and-Valve-Tube/

Measures are in one of the first schematics. You should not print the thumbnail. Enlarge the image with one click on it....

Thanks! That will be useful!

Thanks! That will be useful!

Thanks! I'm sorry but for now I cannot upload the SketchUp file.

Angle is not a precise value, you can change it in three positions. You can also make some measure on your body to find optimal angle for yourself.

Wooow it's awesome!

Hi Klaus! I got your message and answered you, I'm glad you liked my tutorial! Let's keep in touch!

Thanks! 😁

You're welcome!

:) i added link to Italian version in first step

You're right... I removed it for the moment, I'll try to make a better and working video. Thanks!

I'm glad you like it!

incredible project!

that's nice!!

beaufiful project and instructions!!

beautiful project!

WOW! That makes me proud, and it's exactly what I desired when I published this project. I made same path as your, I learnt a lot with the aim to make by myself a Nixie clock, i didn't knew much about electronics, and after one year or two I made this clock. And I felt in love with nixies! Congrats for your journey!

You're right, I used standard bamboo toothpicks!

Hi! I hope you managed to find the switch. Unfortunately I also had very problem finding other switches like that... I only had for of them. You should modify a similar switch to make it work... or use some cables to connect your switch to motherboard. Good luck

No it hasn't, not yet

No it hasn't, not yet 😉

A maker never becomes old, and neither his instructables ;-)You can use water colours but also acrylic ones, I think to remember they were water colours.

Beautiful! Really a cool project for a school workshop!

I love this clock! Awesome project I will try to make one for sure! Thanks!
