case and I/O panel ideas

Postby Newsdee » Fri Nov 03, 2017 12:28 am

I found out recently about a MiST clone that changes the layout to add a few video out options (RCA Composite, S-Video, RGB, VGA). I thought it was a neat idea so I started to wonder about something like that for MiSTer via a custom I/O board.

Certainly it's doable but It would be better if we could house it in some kind of standard case, so we don't need to 3D print a case (just the front and back panels with opening). Perhaps the I/O panel of a Nano-ITX would work? But I'm not sure if there is enough space in the case for the DE10 Nano and cables to make pass-through connections (e.g. HDMI).

Anyway these are just thoughts at this point; here's a rough mockup of what I was thinking:

Basically something like this with a custom I/O shield (and custom front panel somehow).

Some of the connectors wouldn't be on the I/O board though, for example the HDMI, Ethernet, and UART USB would just need to be pass-through connected to the DE10 board. This adds some costs for a tiny cable and custom part for the I/O panel, but I suppose it's easier to install without desoldering anything on the original DE10 board?

And this is the board I was mentioning earlier:

I think, it's better to put MISTer into some retro case like Amiga 1200.
Otherwise you may find some tiny case in radio shack or similar store and make required holes.

Making a breakout board will be too expensive because of size and used male-female connectors. Also size of the whole construction will be huge without any extra added functions.
At least with retro case it will look like retro replica. With this ITX case it will look like face-less brick.

Since MiSTer is DIY project, it's up to user decision which case to use :)

Is there a way to connect the Amiga 1200 keyboard without the Keyrah?

Some time ago i've posted picture of converter i've made in MiST forum. It uses A500 keyboard board + arduino micro. The whole construction makes USB keyboard from A1200 keyboard.
Keyrah's firmware is buggy.

I like Newsdee's suggestion for a standardized case. Makes sense. But it should remain a case and not a new project imho. I like Sorgelig's approach to MiSTer and his effort to standardize the daughter boards as much as possible. It makes it easier to design cases in the first place and also helps troubleshooting quiet a bit.

Not to worry though - all input is welcome and every case, be it retro console, retrofit or new design, adds something to the MiSTer project. I personally like my cases small and functional. Also I guess for an increasing number of hobbyist 3D printing is the easiest method of obtaining the designs of others. Therefore I plan to release updated fronts for my case as well :P

I'm planning on purchasing a mistier soon. I love the idea of more analogue outputs such as composite and svideo, and component. I'd just love to hook it up to my crt tv. I have a hdmi adapter to composite but its very picky with resolution and adds a bit of input lag, at least with my laptop. so i'm hoping this is my solution for retro gaming on my crt with out the actual systems.

This is a perfect on/off switch for the DE10-nano board, 2.1x5.5mm Connector Switch Power Cable on Ebay:

Updated only $1.68
https://www.ebay.com/itm/DC-12V-1A-2-1x ... 2749.l2649

I know this is not really belong here but I don't know where to post it.

It's good, but far from perfect. It won't switch off the PSU itself.

Me too, although the switch is quite big.

Recently i've bough the case for my RPi. It's NESPi - a wonderful case!
If it could be 5 mm wider and 10 mm longer, then it would be possible to fit DE10-nano inside. Actually it's possible to fit in current size but it will require to remove all NESPi PCBs which makes the case not so attractive.
What is really good in this case - it has its own HUB and Ethernet extender.

Is there other similar case for RPi with such breakout board? It could be a candidate for MiSTer case if it's big enough to fit.

found this very interesting Lego NESPi case: https://www.andrerinas.de/tutorials/nes ... ction.html
I wonder how to get those Lego parts. Is there a place to order exact lego parts?

Maybe the breakout board can be bought separately? And then a case could be designed around it.

You cannot buy it separately. It's a custom part made exactly for this case. Eventhough you will get the board (actually it's 4 PCBs!), how you will make the same quality case? 3D printing doesn't provide good quality.
I think it's possible to buy 2 cases and make one longer case :) But it will be too expensive and it will be a challenge to glue 2 parts nicely.

I found one Lego store in my city where it's possible to buy bricks separately. I will visit it and see if it possible to construct a good case.

I was also think of doing a Lego case too, but with the hollow one (Lego technic) to improve the air flow.

The board is 68.6*107mm

This AliExpress seller offer lot of choice in fake Lego:
Here is the bar/brick which will match the length 8*128mm:
https://www.aliexpress.com/store/produc ... 0e37K17LAd

Here is the bar/brick which will match the width 8*80mm:
https://www.aliexpress.com/store/produc ... 0e37K17LAd

The width might need shorter bar/brick at certain places to accommodate the different I/O:
https://www.aliexpress.com/store/produc ... bd1ffKHnvF
https://www.aliexpress.com/store/produc ... bd1fzIgFM2

The closet plate will not fit the width 80*128mm (you need an extra 16mm to fit the 2 bar/brick we will be short of 5 mm) :|
https://www.aliexpress.com/store/produc ... 0f8dQ1Ph76
may be a lot of those plates:
https://www.aliexpress.com/store/produc ... 5ecbki6M1D

Other plates might work, knowing that the SDram board and FAN need to be accommodated

This one seems to be perfect. It is around $10 on Ebay (Aluminum Project Box Enclosure Al Case Electronic DIY - 36.5x80x110mm (L*W*H))
Just need to cut it for SDRAM board and fan events.

https://www.ebay.com/itm/160949209282

This one is little bit bigger (150*105*55mm), still around $10 on Ebay:
https://www.ebay.com/itm/Enclosure-Case ... 0005.m1851

Or this one (External Size : 170 x 130 x 80mm/6.7" x 5.1" x 3.1"(LxWxH) - Internal Size : 160 x 120 x 70mm/ 6.3" x 4.7" x 2.7"(LxWxH)), still around $10 on Ebay:

I found the same as your second choice (150*105*55mm) :
http://www.ebay.com/itm/192244611153

It's almost the same price. And it has some room inside to put some stuff like :
Hub USB
Ethernet extender like this :
http://www.ebay.fr/itm/332137004761
The length of the cable must be shortened, so you have to rebuild the male side.

Sdcard reader (extender) so we can use full size sdcard
Something like this :
http://www.ebay.com/itm/142448597315
It may be possible to shorten the size of the band.

The hdmi port must also be deported.

I like this also, you can remove the top to have access to the different headers if need (110x95x55 $13):
