Downing's OUYA Portable: COMEPLETED! Last Post Update

Post by Downing »

Hey guys! I've been away from Racket Boy for far too long! Coming back with a new mod!

Yup, decided to bite the bullet and make myself an OUYA portable. Why? Isn't it kinda pointless? Why not get a smart phone? Yes I understand it's pretty pointless as there are other options out there, but honestly, I like my OUYA. I like what it stands for and I like a lot of the games on it. On top of this, I also had a lot of left over parts, including an HD 7" Screen and batteries from my original Cross Plane prototype, as well as a couple Cross Plane cases which I wanted to use up.

So I figured why not, it's not gonna cost much and I think I'd actually play this portable as I'm in love with Final Fantasy III and Pin Ball Arcade.

With that said, on to the progress!

So this is what a Cross Plane case front looks like when it comes off the 3D printer. Because 3D printing isn't nearly on par in terms of quality with circles and clean openings, I make a file from the original and leave .0625 holes in place of the button, screen and speaker cuts. This allows me to have accurate starting points when it goes onto the CNC machine which does an amazing job making perfect cuts.
Image

This is what the case looks like after the entire case has been filled and sanded. This has to be done because the gaps in between the strands of the 3D printed casing will show up if it's not done this way. Pain in the ass, and if it weren't for the fact that all the screw posts and mounting layout in terms of a structural integrity didn't make assembly so much more secure, I probably would just still stick to vacuum forming. But that is enough to justify the cosmetic work that needs to be done. After it's filled and sanded, I then spray on a few coats of the Rustolum Filler/Primer which takes care of all the small imperfections.
Image

And here it is after the machining process. You will notice though, I screwed up pretty badly with the Dpad because when I calibrated my machine, I made the stupidest mistake I've made in awhile. When you calibrate this machine, essentially you take a ruler, and set the center of the end mill on a starting line, tell the machine how far you want to move it and then tell it how far it actually moved. This way it can calculate the step of the motors and everything is good to go. Well, the machine works in millimeter units. I grabbed the wrong ruler which was in standard 1/32nds of an inch. Well, as you can imagine, that didn't go over so well and the D-Pad was cut 2mm too small and 2mm too high on the face. So, I had to cut out a replacement face plate and frankencased the plate into the face of the case. I also engraved the OUYA logo into the face as you can see, but I had to make the logo manually in SolidWorks. I think it came out alright for that.
Image

After that was complete, I sanded the whole thing down, found the imperfections that weren't cut out by the mill and filled them in place. Tonight when I get home from work I'm going to sand down the face again, hit it with another coat of primer and it should be ready for painting.
Image

Now, some of you may notice that Ben Heck did an OUYA portable a few weeks ago (I know Gman did as his printing style on his latest project is very reflective of it) that looks very similar in size and shape. However, I hold a strong belief that Ben may have borrowed the idea from The Cross Plane and our OUYA semi-portable we made from it.

So with that, I stand by the notion that I'm not copying him as I in fact had this in place well before he did. :lol:

Now as far as the guts go, most I already have, but my good friend RDC is working on a break down and schematic of the OUYA controller and working on a way to make the controller run off the Bluetooth module and not have to shove the whole controller board in there. We're working on a making a breakout board for the module so soldering right to the module won't be necessary and all the components that are needed to run it can be centrally located. So far he has everything traced and now just needs some testing but it's coming along nicely.

Lastly, the back of the case from the original Cross Plane had cutouts for the control paks that wasn't needed here. As such, I'm having Hail print me a re-worked back half which I should hopefully have in the next week or so, depending on how much he's dragging his feet. :XD So that will be the next step in terms of case work when that arrives.

More updates will be coming soon, so keep an eye out!

Progress!

Sanded the filler down and got everything nice and even. I'm really pissed I screwed up that d-pad, but for what it is, it's turning out ok.
Image

I hit it with another round of primer which is looking decent but I think it's going to take one more round of drying and sanding with another coat of primer before I hit it with the paint, especially around the d-pad as that's standing out a bit more than I'd like it to.
Image

While that was drying, I cut the buttons from the controller and got the PCBs ready for when the case is. You'll notice an extra button on the right side, or I should say an extra tact. That's not going to be used as there simply aren't that many buttons on the OUYA controller. The big button on the left is going to be the controller on/sync button and the plain grey one is going to be the OUYA power on/off. I'm going to need to use a mini rocker switch for the main power because the screen and controller need to have a kill switch, but the OUYA runs off a momentary on/off so if you hold the switch, it turns off. This is why two switches are necessary for this portable when a screen that's running off the same power source is being used.
Image

Anyway, excited about the progress so far and will have more updates after this is done drying.

Looking sweet. Don't sweat the D Pad it looks great. Cool to see posting of mods done by OP, will check back for updates.
Let my legs shake me to sleep, and don't wake me when I sweat on my sheets.

That didn't stop you from making the SNES with built-in controller screens. :P

Ok, Small update.

Got the front half painted this morning. The shots show it shortly after it was painted so once it dries and I get the clear coats on it, I'll take another picture. The D-pad ring stands out more than a white guy in an Asian strip club...It sucks but not much I can do about it now. It's not bad really, but I just couldn't seem to get it to blend as nicely as I wanted, even after several coats of primer and sanding. Oh well...it's for me anyway so screw it.
Image

Normally though a few clear coats will help but the imperfection will still be there. I'm thinking before I clear coat this though, I'll try and fill the OUYA logo with some white paint to make it pop a little more than blend. Not something I've tried before (syringe painting) but I'll give it a go!
Image

Lastly today, I got the HDMI cable wired up. Taking my lesson from my first attempt, I used SATA cable for the data lines that needed shielding, 30 AWG wrapping wire for the additional shields and controller wire for the power, hot line and clock lines.
Image

I'm going to try and hit the case with a few clear coats tonight which means I can start assembling the front half tomorrow. It's coming along nicely I'd say.

Been a very productive morning, aside from the fact my basement flooded this morning... :( Nothing too bad as it was expected so I got everything of importance moved, but I've been working with wet feet all morning...yay for electronics and water!

Anyway, on to what you really care about.

This is the case top after three clear coats. I just read that Bungle likes the Krylon clear coat. While I agree I like that, I must say that Rustoleum Clear Coat Enamel is the best clear coat I've ever used. It dries quick, is very finger print and scratch resistant and applies very nicely. The only downside is while it's scratch resistant, it's not "dent" resistant, meaning because it dries but remain flexible, it will leave impressions if say a piece of plastic from a dremel or something applies pressure. That sucks and it happened to me this morning as well...blah. Also again, I'm not happy with the D-pad and how that turned out, but oh well at this point.
Image

So I got to start mounting parts into the case today. Everything fit together nicely. Looks like a jumbled mess in there, but really it's not that complicated.
Image

And here is the front face completed! I did mention that I was going to try and paint the OUYA logo to make it pop with some white paint. Well, what I actually did was scrape the paint out of the logo cuts and because the plastic is so thin where the cuts were made, I LED back-lit the logo with 4-5mm white LEDs that will turn on when the system does. I think that's going to look awesome!
Image

So I'm about as far as I can go now until I get the back case half from Hail and the breakout board from RDC. I'll of course work on wiring what can be wired up on this half, but for the most part I should be just about done with the front face. More to come soon!

Just a pic that shows my home-made HDMI cable working as it should! Done right on the first try at that!

Image

Sweet! I'm liking how this LED back-lighting is working out! Not my best soldering on the inside but it's secure and holding steady so I'm gonna go with it!

Image

Image

Still debating if I want to add a couple more to kind of fill in the dark spots but I'm not sure it would be worth the battery time, though really I have no intention of sitting on the thing for over 4 hours.
