Can anyone who's made this post some close-up pictures of the electronics and how they connect? I'm a total newbie at this and want to get it right. Thank you so much!!

Hi, I just finally wired mine together and am so happy to see it finally come together. One question I have is that I'm only getting purple and orange LED's cycling, and no other colors. Any idea what I need to adjust to get to the other colors? I'm also getting it spinning the new color in, in sort of a rotating wheel of LED's, rather than a pulse. Any idea what I did wrong?

You didn't do anything wrong, it seems I uploaded the wrong code file. I don't have the code I wrote for the rainbow cycle anymore, although I believe it was copied from the rainbow function from the neopixel strandtest code. If you are comfortable with programming Arduino you can find the strandtest code online and modify the code that I uploaded.

No worries, I appreciate the response. I actually reached out to Reddit and a kind person helped me out with it. I've uploaded it here (although I'll remove it if you're uncomfortable for some reason) just in case someone else comes by and needs it.

Thanks again for responding, and posting this project in the first place!

Thanks for the new link! Very helpful. The orb is already printed and turned out great.

Hi Working on this great project with my daughter. The link for the push on / push off switch does not work any more. Can someone share a particular switch that you used so I know it will fit properly? Thanks!!

I replaced the broken link with a working one. For reference the switch is 8 x 8mm. You may be able to find a better deal on the switch from another website so don't feel like you need to use the website I linked.

If you are able to modify the stl file you could make it work with a different size switch if you want.

Hi ! This model is insane, I'm trying to build my own but I'm not good in electronic... Do you have a schema of the circuit you've built ? Thank you :)

By the way, what have you used to print the transparent diffusers ?

I do not have a circuit diagram but I did include a photo in the gallery that shows all of the electronics wired together.

I printed the diffusers in a translucent white ABS material.

I'm kind of new to electronics so this might be a dumb question, but why did you use a capacitor for the lights?

This model is absolutely fantastic by the way.

The capacitor serves as a buffer to filter out potential voltage spikes and protect the LEDs from frying.

Comments deleted.

I apologize if this seems like a really stupid question, but how do you have 4 wires soldered to the capacitor?

The capacitor is wired in parallel with the LED strip. The two red wires are soldered to the positive terminal of the capacitor and the blue/green wires are soldered to the negative terminal.

The walls are not a constant width. Are you interested in the minimum thickness or maximum thickness?

Maximum, please? my teacher wants to know.

The maximum wall thickness is approximately 20mm and the minimum is approximately 4mm.

Also, do i have to do anything, like scale the button files? Because in the stl files, they look as though they are larger than the shell

No, everything should be scaled to the correct size (notice the grid size in the stl preview)

Hey there, I'm a bit new to 3d printing, this model may or may not have been the last straw for me to pull the trigger. Just wondering how this (the main shell) is printed do you just have supports everywhere and then have a ton of cleanup? or is there a particular angle that makes it easy. Really itching to print this.

I suppose that it depends on what slicer you use to prepare the model. I printed the model in the default orientation and there were a decent amount of supports to remove (see attached images). I oriented the model so that most of the supports were inside the model to preserve the quality of the outer surface.

How did this go for you? I got all my prints done, got all the electronics finally, and have been working with spot putty to even out the layer lines and make this as prefect as I can. But I have zero experience with electronics whatsoever, so all this new stuff is a bit daunting. I anticipate frying a whole lot of stuff before I finally get this right.

This is excellent! I have printed all the parts (nice work, by the way!) and the electronics are on their way.
However, I have no experience with arduino. Do you have a sketch/sample file you could upload for the LED program?
Thank you!

Hey there. I've uploaded the .ino (arduino code file) to the thing files. The code is pretty simple and just cycles through the colors of the rainbow. I've also linked a helpful article in the thing details which explains how to to get started with programming the LED's in arduino.

Awesome, thank you! this is very helpful.

That would be wonderful!

See my response to DANQUISH. I've added the code file and a helpful article about programming the led's in arduino. Hope this helps.

What did you do to smooth it out or did it print like that?

I printed it in ABS and then vapor-smoothed it with acetone. You lose the crispness of the edges but you get a nice glossy appearance. I wish i'd taken photos before I painted it...

I have no experience with electronics, but I just want to be able to do two things with this orb: Make it light up and make it hover. I've already found an instructable on the latter part (http://www.instructables.com/id/Electromagnetic-Floater/), but I was wondering if you could point me in the direction of a way to provide light without all the fancy gubbins. I'm guessing I'll need some strip LEDs in place of the RGB ring but that's all I've got.

On a related note, I'm making a mold to cast the diffusers in clear resin. I feel like that would be a more accurate display and have a better look to it. Info on the mold-making: I'll be using Ooomoo 30 (50ml of both parts A and B for a total of 100ml, by my calculations) to fill a 3.5" x 3.5" x 0.5" foamcore tray that has a diffuser hot glued to the bottom flat-side down. It's just going to be a one-part mold and I don't think the angles are acute enough to warrant having to cut the piece out; the silicone should just stretch enough that I can pull it free.

I thought of making the model hover, but never got around to it. If you get it working you should definitely post a "make" with pictures, i'd love to see it.

As far as lighting goes: if you want to simplify the electronics as much as possible I would recommend going with battery powered LED's, you'll probably need a few LED's per ring (4-6 minimum). You may need to modify the CAD file to fit the batteries and LED's. You'll likely need to modify the electronics housing to fit the batteries you are using, and you may need to deepen the grooves that the LED rings sit in in to accommodate the size of the LED's you choose.

You certainly could make a mold of the diffuser. My only concern with using a clear resin is that it may not diffuse the light very well and you may be able to see the individual LED's. I'm interested to see how it turns out.

I see you are using a 3,7V Battery but the leds say that they need around 5V.

Can they work with just 3,7V?

Yeah, mine worked fine. I think the rings I actually used are these ones I found on ebay. They're cheaper but they work the same.

Thanks! You are being really helpful!

Hi there,

I have a quick question on the "diffuser." Did you print that part in a translucent color or paint it? I am wondering how the light would show through the diffuser if painted. Just finished printing all my parts and moving on to the paint.

I printed it in white ABS. The light might not show through well if painted so I recommend printing it in white, that way you can make it any color by changing the LED color.

How did you painted it so nice? Spray?

It looks really cool, i hope you throw it to the people you hate lol

The gold and silver are spray painted. The black is the natural color of the ABS plastic (i masked it off when painting). Someone with advanced painting skills might be able to add some weathering effects and color variation to it but I kind of like the clean appearance.

Thanks! i will make one soon.

Could you possibly post a couple good images of how you have your adafruit circuit? I'm fairly novice with the actual electrical engineering stuff, but if I have good reference images I can manage.

My print is done, and all of the components for the electronics are on the way. It would be amazing if you would share diagrams or anything related to how to do that bit. Thanks in advance.

Can I print this with my 15x15x15cm printer?

Yes, the outer diameter of the sphere is 9cm.

have you considered using a trinket to control the leds?

Yes, the LED's are currently controlled by a Pro Trinket 3V.

my mistake. i meant the mini trinket

it's what i've used in my iteration of the zenyatta orb.

Ah, I see. I suppose that would have worked just as well as what I used. The smaller size is nice... it did get a bit cramped for space inside the ball with all of the electronics.

yup. i ran into that same issue. mine may be a bit smaller internally compared to yours. and the buttons i have are nice and all, but ultimately take up alot of internal space.

I started the new one now and made a nice stand for it. Just waiting on the list for electronics THANKS!

What LED's did you use can you send a link?

I used four 16 NeoPixel rings. I'll upload the part files and electronics list soon.

I printed this already will I have to re print the orb itself? I really want mine to have lights it looks so good!

Yeah, sorry. I made a lot of changes to the design to allow it to accommodate the electronics so you'll need to print the new part files.

OK no worries Will the electronics fit inside everything and not be seen? also whats the time on upload? I want to work on this ASAP :)

Yes, the electronics are contained inside the sphere and cannot be seen from the outside.

I just uploaded the part files so you can start printing. I'll post a list of the electronics I used later.

Awesome I am printing the new one now, let me know what electronics you used.

I've added a list of the electronics I used to the model description.

Hey thanks for the list! A little pricey then I assumed for everything. Is there Soldering involved or is it plug and play?

There's quite a bit of soldering involved, this is definitely an advanced project and not really plug and play. You can source the components from other locations with lower prices if you can find them (I found less expensive LED rings on Ebay, just be sure that they are compatible with the micro-controller.) Good Luck!

This is a really high quality model dude, it prints well!
