Input and output airflow I guess?

Two fans?

Yeah haha, I know its way over kill but I had one of the fans in another case I designed and I didn't have anything else to do with it. Plus more air flow never hurts.

Yeah that's right! In through the top and out the back.

My MiSTer case is a bit oversized, and I'm not finished assembling it yet, but you can see it tucked inside before I put the last cover panel in the front: Note, the back of my MiSTer case will have six dresser drawers in the back for clothes, and a small cabinet space for shoes and sundries...the side panels open like doors and the drawers will pull out the side.

Airflow is limited, but there is a decent volume of space around it to prevent heat soak.

Looks good and a nice idé to turn it into a "The MiSTer DreSSer" (i think i would make a sticker/paint that name on it).
Did you cut the plywood yourself or is it a kit?

I used the router path for Moon Patrol from Classic Arcade Cabinets, generated a list of circle centers and radii from the corner along with starting and ending lengths along the edges, and re-derived the outline on the plywood, laying a straightedge along the tangents. I then clamped down jigsaw guides offset to those lines, cut the profile for each straight, then cleaned up the corners and edges with a router. The first side took about 5 hours, and the second one took about 45 minutes...I just used the router to copy it like a key at the hardware store!

It was actually rather fun to layout and a little stressful on cutting to make sure I didn't encroach into the profile, but it was really satisfying!
There isn't a single screw in the frame, either...it's all dowels and biscuits!

The entire frame is free-standing without the side panels. The drawers will go in the openings at the top, bottom, and just underneath the control panel mounting platform. The hardware installation is obviously unfinished in this image - no keyboard will be necessary and the power supply will be mounted on the ceiling of that section.

I finalized my SNAC Board.
And as I have enough space in the case i simply put it inside , between the two USB Adapters.
Mega Drive and SNES Controller are working well

This is f'n awesome!!

Maybe a complete run down is in order? (well except for the proprietary .stl files of course, if you don't want to share)

[Edit] I mean what's the size of that LCD panel, specs, where'd you get it, speakers etc. Details man, details!

Thanks!
About the screen, it's an iPad screen with a controller board you can find in Aliexpress or ebay. Some info in this thread:
viewtopic.php?p=6344#p6344
I will make adjustments to the 3d model, it's not finished yet.

Very cute! what kind of PSU are you using? It looks like that black box up top is a step up or step down converter? I have an iPad screen I'm building and a MiSTer I've finished, and I'm using a 12v 60w power supply to power the screen (12v x 2-3a = 24-36w), and it also goes to a 12v -> 5v 5a step down converter that powers the MiSTer and a little amp for speakers.

A couple questions: are you using the "digital" speaker outs from the LCD driver board (the little four pin JST connector)? Is the volume just controlled through the OSD? I want to preserve my headphone out on the board, but I also want hardware volume control for the speaker, so I'm using a tiny amp with a volume control. And you don't happen to have a pinout (or know how to work out a pinout) for the little remote control for the board, do you? It's a weird shape and tough for me to mount, so I thought I might make my own, but I don't know completely what I'm doing with that. I assume momentary switches going to ground or 5v would work?

I'm using a 12V 3A power supply. Yes, the black box is a step down converter (12V to 5V)

Yes, the speakers are connected directly to the 4pin JST connector of the screen controller board. The volume is great! The vol up/down is controlled through the OSD, it can always be refined in the MiSTer OSD (Core Volume). It would be great to find a way to have hardware buttons to control it, I've searched for it but I haven't found anything. If somebody comes up with something, i will be more than happy to include it.

About the controller, i'm designing my own board (my first time designing a pcb!) to include the MiSTer on/off switch and the three MiSTer buttons. To learn about the pinout of the board you can check it with a multimeter in continuity mode. This is what I found. Pin8 would be the closest to the CN1 text on the board. I've switched pins 5 and 6 to maintain the same order of the buttons and the order of the icons in the screen's OSD. (For example if you check my first picture, you'll see the green and yellow cables are switched. With the board I'm designing this won't be necessary)

You’re the best! Thanks so much for the control diagram; it makes perfect sense. For your volume control: it isn’t buttons, but what about just a stereo 10k audio pot? You have me thinking I don’t need my extra amp, and that’s what I’m planning on doing. I know normally your volume pot comes pre-power amp, but it’s such low wattage that I doubt it matters here.

Beautiful work

I'm a sucker for "all-in-one" designs, and this one is very clean! Excellent use of display, and the custom PCB is a really nice way to stay tidy. Inspiring work!

Derick2k wrote: ↑Sun Oct 25, 2020 2:54 am After seeing so many great cases I decided to jump in and put one together. All off the shelf parts with some acrylic mounting plates I cut. I didn't want to solder much/remove headers, etc..just wanted to do it quickly, if I would have gone with a custom wire job I could have put it in a much smaller case, a bit more neatly. Went a large 120mm fan, very quiet while moving massive air, didn't make sense to pay almost the same price for the smaller 40mm fan from Noctua. Now to actually turn it on, hopefully, it doesn't go up in smoke

I love your design what is the make and model of the case ?

AluMiSTer looks fantastic need more details

It's the new aluminium case Porkchop Express (misteraddons.com) has just started selling, I just finished putting mine together.

This looks ace!
...but no provision for the BlisSster board unfortunately

my case.

Now that is pure art, using a custom pcb in that gamecube casing, nice work!

Ok, that's about the coolest thing I've seen

Are you selling them or making the gerbers available?

This is our arcade table. Usually it has a Raspberry Pi sitting inside it, but I've been using the MiSTer with it recently instead. I haven't quite figured out *where* to put it - so it's actually sitting on the floor just out of shot. Usually the Pi sits in the shelf area under where the monitor sits, but it's not big enough to store the MiSTer safely.

The table is cobbled together from bits and pieces that we had laying about a couple of years ago.
The base is an IKEA Lack side table, with a big hole cut out for a Philips 22" monitor. I took the bezel off it as it had silly touch buttons that had failed anyway, and it made it a much nicer shape to fit.
The buttons and sticks were some "zero lag USB encoder" kit found on Amazon, and were surprisingly better quality than I expected.
Annoyingly, the monitor only has DVI and VGA sockets, so I'm using an HDMI to DVI connector at the moment as I don't have the Analogue I/O board. It also means no sound either - for the Pi, I've got a small USB speaker that just connects to the audio out port. For added fun, the viewing angle is best when it's upside down...

Other cobbled bits I have for the MiSTer is an old Maplins wireless keyboard, an Amazon basics USB hub, and a USB WiFi dongle taken from one of those old Tesco Technika "smart box" things that used to be everywhere. That also seems to work better than expected!

Hello mike, nice case and nice colors! please may i know what filaments have you used?
thanks

Hello!

Here is my MiSTer installed in a cheap chinese Mini-ITX case, along with 3d-printed front & back panels.

• The metal case is sturdy, only front & back are 3d-printed plastic
• All connections go out from the back
• A couple USB connections in front for good radio signal
• Uses some random old USB hub
• No I/O board
