My gosh those tubes are a dream!!! 😱

Hey that car is beautiful! 😱

That's an impressive project, thanks for posting!

It's beautiful! Thanks for sharing! :-)))

I actually don't have an answer, i think local supply stores are the best choice in Italy... but a good plywood is quite rare here and very expensive.

Awesome project! 💪

It's strange, I can read them on my android phone. Maybe it's a compatibility matter, if you could tell me your email address I send you the picture.

yes, I agree with you!

I don't know, they probably double the size.

There isn't. Connections are very simple: connect battery to both circuits, and a switch to cut the power. The audio jack from the radio goes then in the socket of the mini speaker.

Thanks Bob! 🙏

So cool

My gosh, I'm happy for you, and the ring is a beautiful small art piece!

I have the same exact lathe! Awesome job!

I think that you have the most fervent imagination! I admit that this project could be improved, maybe with a plastic pipe for hydraulic home system instead of used glasses, but it's a beginning! 👍

That's great! I am interested in a deeper understanding how you connected the battery and the controls to the motor.

It's beautiful and well done! 👍

Thanks Jessy! I'm happy you found it, after all this years! 😁

Can't wait to see it! ;)

Beautiful! I love the suns! 😆

I believe that an hand saw, a drill, some screwdrivers will be enough. Maybe an hammer too.

Oh, thanks, that's a good advice.

That's really precise, artistic, and so beautiful!! Well done, it's a great activity for an art class.

This is realisation, you must look the instructable about project! Now I add the direct link in the first step.

I followed your advice and updated the ible with new version PSU!

I added links to ebay seller!

I also prefer reuse and recycling more than 3D printing, but I like so much 3D modeling too.I'm sorry I'm unaware of the 3-pin plug purpose..

I glued the display from inside, with a little bit of hot glue.I don't know what are those connectors... I wondered too.I'm not sure the circuit is protected, but I should check... same thing about overheathing. There is a good review on youtube, you could find answers there.

Well done! I've always desired to build my own oven!

It's really tiny!

My gosh, it's such a great project to teach programming, gcode, excel, and so much else! I personally don't like much the pipes solution as it occupies a lot of space, but you made an incredible machine.

I can't wait to see your design! It will be awesome with batteries!

That is a very useful board, as you said many times a 16x2 lcd display is not needed, and an old school 7 segments led display is great! Furthermore it's more compact and suitable for small devices. Well done!

Ouch! Yes, you're totally right! That's a terrible mistake!! I'll fix it ;-)Ampere times hours is the electrical capacity, like how much energy is contained in a battery.Thanks!

Yes, exactly, the stability is great, due also to good rubber feet. My little nephew asked me if the case was magnetized! ;-)

Yes, they would be handy. I tried to make a device similar to a professional power supply and I preferred these.

Because it's a personalized power supply! ;-)But I wrote in the ible that I didn't have a small brushless fan, and I will use it for sure in next version. This motor is undoubtedly too noisy!

Awesome and really useful project! I also teach online and I would have had this before!

I'm teaching physics in middle and high Waldorf schools. I had to show experiments, write descriptions, discuss the process, and I obviously try to remain always visible to students. Sharing screen is not always the better solution, since my face will be probably seen quite small. Your transparent board will be great! And mirroring the screen will solve the difficult to write backwards! Yes, please let me know how it will work.

Well done!

Awesome project! Congrats for the prize!

I fear that soldering will heat batteries too much, it's surely harmful to li-ion cells, I'm not sure about other chemistry...

beautiful! As for the labels, you can transfer toner from a laser print to your console with an iron, then remove the paper in water.

that is a huge project! Congrats for all your efforts and goals! What about the fail to align optics? Can you tell us more, or maybe I missed something...Thanks!

Anyway i think that naked eye will see more colours in the spectrum, since camera sensor has probably a narrow range.

It's a beautiful project! I made an optical spectrometer for my physics class, with no camera. The camera is great for a class!

Awesome science experiment!

Did you find answers to your questions? I also built a li-ion battery pack with a BMS for a drill, but I'm not sure how the BMS will charge it... May I use a laptop PSU? The voltage is right (about 19V) but what about the current?Thanks!

Woha! And i simply LOVE fractals!

your wife was surely happy, this is a noble purpose for 3D printing!

beautiful work, thanks also for talking us about your mistakes :-)

that's a lovely present!

It's really beautiful!

My gosh this is gorgeous! It really seems a big little vintage light bulb!

It works with a few milliamps, 200 or less 👌

Look at the Arduinix project made by Jeremy Howa and Brad Lewis, I spoke about it in step 1. That project uses two drivers, but I wanted to try with only one, so my multiplexing is faster, a little too much, but it works quite good. On the code you can see that it only lights a single nixie for a bunch of milliseconds. Total consumption should be the same..

Haha si sono italiano! 😁You're probably right about wood-glue on rubber and metal, it wouldn't adehere permanently, I think some glue like uhu could work.
