I'm interested in remixing and personalizing the case.  Are the STL files available for download?

You can download them from this location: https://ataribits.weebly.com/cv-nuc.html

 

This webpage has all the released files for the CV-NUC+ project (e.g., STLs, Gerbers, Schematics, ect.).

 

Please post some pics of what you come up with in this thread :)

^ Thanks for that.  I went to your page before but for some reason I couldn't find the link.  I think I'm getting more and more stupid with age 🤣

 

I'll definitely post my results, although it will be a while since my TBA kit is still being prepped before shipping.

No worries, I do stuff like that all the time 🙃

That would be great when you get to that point.

 

Lately I've been working on a new case design for the Atari version to accommodate a new upgrade board that's in the works. As I've been doing this, I've reflected back on the CV one and have been thinking that it would possibly benefit from some tweaks, but I simply don't have the time right now to get into it. So I'm very interested in what direction you go with this.

I'm still in the abstraction and initial stages.  Basically I'm thinking of mostly superficial aesthetic changes that include ColecoVision specific design elements.  It seems there should be some brushed aluminum at least on the front, but this may be too much silliness.

 

I looked up your 576-NUC+ upgrades and the new case design.  I like the new case design with the strong XL design elements.  What are the temperatures like with everything packed in there?

This a prototype of the new 576NUC+ case design in the works...

It picks up a little bit more of the XEGS style, but with a Dark VADER theme. The badge is designed as a separate print that inlays into the case front. I think it goes well with my mini black PS/2 keyboard sitting next to it 👍

Nothing silly at all about that. In fact it could be done in a similar way to what I did with the XE badge, only rectangular. And to give it a brushed metal look plus to tie it into the original CV style, perhaps a metallic sticker could be made that is applied to the badge, also sporting the CV logo of sorts.

And of course there are other design elements that could be added as well.

 

In some of my early imaginings I was thinking it should look a bit more 'Coleco'. Unfortunately by the time I got to doing the case design for the CV-NUC+ I was getting a little burned out and rushed that through to the finish line.

 

I don't know if this will help in your endeavor, but here are the 'blank' STL files that @Mr Robot shared, forming the basis of my first attempt at a CV-NUC+ case.  EDIT: they're contained in the ZIP along with the completed 576NUC+ case designs.

It's actually not bad at all, although I did put heat sinks on the Antic and GTIA graphics chips to be sure, since they always run hot (similar to the TMS chip).

 

The CV-NUC+ case gets a chimney effect from the cart port, and might even be fine without the upper diagonal vents.

^ Thank you, that will be helpful.

 

The part of the case photo that you cropped is really close to the minimum needed to convey the CV aesthetic. 

 

When I was looking at your blog and the video of the case I noticed how you did the badge.  I was considering that as a possible approach with a CV-NUC+ case but using one of the PLA "silver" metallic filaments.  I think it calls for some experimental prints.

I think those upper vent ridges are an integral part of the CV aesthetic.  It would definitely be easier to 3D print them as solid and without vents (easier to clean, too).  More experimental prints.  😀

 

(For some reason I mistyped "XL" styling when describing your new 576-NUC+ case.  It's definitely XE / XEGS styling as you kindly pointed out.)

 

Interestingly, your CV-NUC+ case looks a lot more XL.  I think a gray / black or cream / brown combo with those similar XL accents would definitely look good on the 576.  Your new case design is strongly XE and looks good as well.

Well there's a very good reason for that, because it was based upon the 576NUC+ XL LID Blank STL. I had 3 choices to begin with, and that seemed like the best of the 3, with the XE style not being a contender due to the slanted vents interfering with the cart.

I think on the original prints that @Mr Robot did he was using some similar colored filaments.

Yep that would definitely be a good approach to try 👍

I think I've got the last set of boards from Larry :)

Case printed (on trusty Voron 2.4 ;) )

Just started assembling (fast delivery of components from Digikey to NL).

Still waiting for a couple of parts from other sources (video, 554 and 4416 memory chips).

I hope it will go as easy as 576NUC+

The only thing is - I have no cartridges. Need to look at ebay or our local marktplaats.nl

Will post some pics once it will look more complete...

I thought I should post this here as well on my website.

 

!!! WARNING !!!  Not all SGM Physical Carts are guaranteed to work, although the equivalent digital download versions using an AtariMax Ultimate Cart often times will work.

 

This is something that came to light over the last 6 months. I and a fellow beta tester had run all the SGM game digital download tests via an AtariMax Ultimate SD Cart without any issues during the R&D development phase. But first one and then another end user discovered that a limited few SGM Physical Carts would not work (apparently they didn't pass the SGM test performed by the game). Obviously it's a timing issue between the physical and digital download versions, with the digital versions via the AtariMax cart usually working fine. If I knew specifically what that difference really is, there may have been a way to correct it possibly through a CPLD update. However I'm presently at a loss, and I'm obviously not going to rush out and purchase a bunch of physical SGM carts to find out, since I already spent a considerable amount to fund the R&D on this project.

 

As I mentioned only a 'few' SGM physical carts have not worked, so it doesn't appear to be a chronic problem. But I felt it only right to point this out to potential buyers and/or builders.
