I'm not really sure how this works? How are you reducing the thickness if you still have this giant protrusion that the controller is in?
Yeah I suppose I could have worded that differently huh...haha. What I meant was the overall thickness of the main body of the casing, where as if I didn't put the raised panels on the top of the casing, then the room for the button mounts and the screens thickness would have to be added to the thickness of the main body.

Thanks for pointing that out. Often times I know what I wanna say but what gets written down is something else entirly!

OK! So after a very very productive weekend, the casing is finished and the clear coat is hardening nicely. Though I'll admit that I still don't have the painting/finishing skills of others, I'm quite happy with how this has turned out regardless. Yes you can still see some scratches and component outlines, but this is the most beautiful case I've done to date so things are improving.

Anyway, I'll tell the rest through a picture log.

I reformed the control bezel because I wasn't liking the layout of how close the buttons were together. The big problem though was my drill bits attacking and snapping my plastic instead of drilling it. Well I found the answer to pretty much all my plastic hole drilling problems in the next photo. But as you can tell, the layout is much cleaner and more user friendly.
Image

This is what's called a stepper-bit. This one goes from 1/8th inch to 1/2. By starting a small centering hole with a regular drill bit, placing this one in the drill takes just little shavings of plastic away at once in increments, smoothly and gently. Get one of these and you'll never have problems with making drill holes again!
Image

The Screen and Control Bezel PVC cemented in place. For this, I placed these on before I cut out the back sides of them. This allowed me to draw an outline of both bezels and load up on the inside of the line, a lot of PVC cement. This in turn allowed for a solid bond to the surface without the need for massive amounts of filler to fill in the edges because the bezels are actually sitting on a solid flat surface. This is how it looked "After" applying the cement and cutting out the back. Not too shabby.
Image

The next two pics show the mounting system for the tact switches for the ABC XYZ buttons. Just little strips of styrene built up and super glued in-between layers to promise a tight and strong hold. The buttons will then be glued to the tact switch tips therefore preventing rotation and keeping them in place.
Image

Readjusted the alinement as you can see in the later pictures so the tact buttons will hit center. The two small buttons on the bottom left are for volume control, using that mini amp that Hail showed us in the Reference Section.
Image

The rest are all dark pictures of the paint job. I put three coats of Satin Krylon Fusion and three coats of clear. Once these harden it will prevent finger prints and hide some of the imperfections which are quite apparent, but still beautiful in my eyes!

This is where the rocker power switch is going. Was a tight fit and will be again now that there is a few layers of paint, but that will clear up with a bit of filing.
Image

And the top where the game is going to fit into the cart slot. Had to change my original design because of space issues, so the game facing the front now instead of the back is how it's going to work. But that's not a bad thing. I'm going to try and retro-fit the Genesis 3 doors into the system so the top isn't exposed when no game is in place, but we'll have to see if there is room.
Image

Anyway, all that's left is to wire up they system, tacts, batteries and mount the system securely in place. Have a feeling I'll be redoing the cart slot again though because of how my batteries need to be laid out, but we'll see where that lands next weekend!

Whoa that looks way better post painting! :shock:

Personally knowing how small the pcb is I would have aimed to make it even smaller but whatever.

Why? Smaller is not always better. Ref: Gameboy Micro. It looks like the width is kind of dictated by the controller button layout. I would much rather have a slightly larger system that I can comfortably play than have an uber tiny system that hurts my average sized hands to hold and doesn't work right because my thumbs keep kitting the wrong buttons.

Again, it comes down to what you have to work with. It's not just the mobo that takes up the space in a portable, it's all the other components that add up as well. I mean I could have made this much thinner if I'd decided to let the game jut-out at a right angle, but I wanted to have it internal. So right there you have the thickness of the mother board, the caps and chips of it (removed power switch so that's gone), then the thickness of the cart slot and the difference of the cart thickness itself with is about 1/4".

Batteries, control boards, tact switches, screen, speakers, power switches and wire all take up space which most times is constrained down to the 16/th of an inch. I admit that I might be able to shrink it down a bit more but honestly, for having everything internal, the overall thickness (including the bezels) is 1-3/4".

I made the Nimbus II about a 1/4" thinner than that, but the cart was sticking out at a right angle. Everything here is enclosed and the case should close up nicely. Hoping anyway because I hate getting to the end only to have to fight with closing the damn thing because of wires and other addional thickness' that weren't considered in the plan.

Small update.

Got the D-Pad and the ABC XYZ buttons mounted as well as the screen. Forgot to take pics of the inside, but not much had changed other than how I mounted the tact switches on the D-pad. Not particularly feeling the tactile feedback from the D-pad as it feels like I need to push the rocker down into the case before it trips the switch. However if this is the fact, it will be an easy fix just to add spacer between the d-pad and the tact switch as those are not glued to each other like the buttons are.

Here's a pic. Started wiring the battery as well, just have to connect the 4 cells to the protection circuit. Did manage to send 8.145V at 2000mAh through my finger and up my arm though. When you take apart these BP-915 batteries at 2000mAh, they are rectangle cells, not round like in Bac's video. And, the are wrapped in a conductive foil. Well I didn't know that and by slight accident I touched the flat battery pad to the foil with my finger, made a spark and swore like a sailor!

Anyway, I put it down after that and figured I'd screw with that another day.

Here is the pic of progress so far.

The gameboy micro failed not because of its small size but because of the pathetically small screen.

Well, I don't really see how they could have put a larger screen in there.

Thanks for all the tips and pictures. Really interesting. Funny too.
I´m sure this will inspire others to venture into the world of console creation!
I´d like to make a Portable Saturn with a huge screen some day. I´ve modded several thing, but have never gone as far as this.

Nope and that's the best part. Put the time in and you can always push yourself to go just a bit farther! That's what I love about this hobby! Anyway,

Didn't make much progress tonight, but I redid the D-pad and now I think it's too tight...finding this sweet spot is becoming a bit of a pain. Though there is enough free space so the D-pad can move a bit, I'm just concerned that when I'm pushing one direction, it might trigger another one inadvertently. We'll see though.

I also cut the hole out for the charger jack and mounted that in place.

Now I'm working on actually mounting the cart slot to the inside of the casing instead of the actual Sega PCB. This will allow for a finer adjustment when I permanently mount it because when it was glued to the PCB, I could only adjust so far before the board itself would hit the side of the case and not allow for the game to be properly alined.

The system will still sit on top of the cart like it did before and the room underneath will now house the controller PCB and the batteries. Trying to wire this as smart as possible because I hate going to close up the system and because of the wires it ends up being another take-it-apart and try again deals. Here are a couple of pics.
