How will it work if its a U shape? Won't that completely expose the keyboard pcb?

If by 'completely expose' you mean the edge of the PCB on 2 sides will be exposed, then yes... Is there a problem there that you think needs solving?

The whole PCB is already exposed on the top in a sense since if you spill something on a Poker it goes right down onto the PCB. If it were a U shape the only difference would be that you could see the 2mm thick side of the PCB from two directions, but really that exposure wouldn't be that much of a problem at all.

Some people think it's cool to be able to see the insides like that, but for now I plan to do all four walls unless there's an issue with it.

That would make the pcb prone to dirt/dust - more-so than it already is and not to mention would make it look ugly (imo)

I would prefer not to see the pcb. Would look incomplete to me.

Is there any estimation on price yet? Or is it to early for that?

Metal = cheap. Labor cost = dunno. I'm getting this done Thursday though so you shouldn't have to wait long to figure out!

No worries just wondering if you had that figured out. Can't wait to see the result. With all the group buys I'm not sure if I'll have the dough but I hope so.

Somewhat... but it would also be really easy to clean as well.  No taking it apart and finding out just how much more dirt was in there than you expected when you go to clean it.

4 walls vs 2 walls the only material difference as far as i'm concerned is that there's no need to bond the edges together. cheaper labor costs, and will probably look better, as the welds will need to be sanded down to be palatable.

So what type of steel are you going to use and what thickness? Also, how are you planning on finishing it....paint, just clearcoat?

I honestly think that using something like 14ga 304 stainless and leaving it unfinished would be the best looking and most rugged. I would pay extra for that.

Also, I think four bends is the only way to go. Don't really need to worry about welds/gaps in the corners as long as the cuts are good (i.e. laser or plasma cut). I think the U-shape would look awful and cheap in comparison.

EDIT: I just noticed that you are planning on 3/16" thick steel...I'm interested to see how this turns out (I think it will be a bit too thick). Just so you know...the dimensions you listed with a 3/16" thick piece of steel will weigh in around 3.2 pounds.

Maybe I'll throw something together in Solidworks at some point.

Just my $0.02...

There should be a raised section in the middle of the case that supports the center of the PCB.

While I had my Poker it was the flex in the middle that made it seem inconsistent compared to any other mech.

Obviously you would have to buy some non-conductive tape or something to put on top of it...

can't do this. the case material will be conductive, and besides the bottom of the pcb is uneven due to both components and pins. what this will have instead is room to put a soft esd-safe mechanical coupler (read: a sheet of cushy nylon).

this would be awesome. if you do this, don't feel constrained to oneproduct's construction method. i believe i should have access to a 4-axis cnc on campus.

One of those non-slip mats would probably be best.

Having now thoroughly read the OP I can see that it's already been thought of :blabla:

Nice logo Bertross. Like I said, I don't think that they have anything that could engrave that into the metal, but I'll bring it along to check.

Is the conductivity that big of an issue? Seems like imsto's cases don't do anything to stop the PCB from touching metal nuts seated on the metal case. http://i4.photobucket.com/albums/y146/eddie84/OCN/Mech%20keyboard%20club/KBC%20Poker/Poker%20case/DSC06648.jpg

Those are the only places that the PCB touches.  Those parts of the PCB are designed to come in contact with the case.  If you were to put a ridge in the middle as was requested it would have to be carefully measured and placed so as to not come in contact with any of the solder or leads sticking out the back, nor with any of the plastic parts of the switches so that the PCB can lie properly.

a single ridge wouldn't help anyway. you need to mechanically couple the whole damn board to the case or it's always going to flex

no worries, I've neatened it up a bit, let me know if you need an illustrator file. Ill just email it to you. I have some ideas with its whereabouts to.

I reckon on the underneath, or a small KBC one where the TKL filco sits.

he would need a pretty high powered laser cutter to engrave. presumably he doesn't have access to one of these things, or it wouldn't be too hard to cut out the holes we want in the sheet

yeah true, was just an idea really. You could even do an insert cut on the bottom and get it engraved at a jewellers on a small trophy plaque or something like that.

Well, this was suppose to happen today but my friend didn't answer his email or texts, so I presume that he's somewhere over the Atlantic ocean or sleeping off jet lag since he was coming back from England today. Will let you know what's happening as soon as I speak to him again.

Okay, got to him today and brought it to one of the white collar guys in the shop who will be arranging production. Most likely not going to be doing the indentations so that the PCB can be screwed directly into the base of the case though unfortunately, so it will be more like imsto's version where the PCB rests on nuts. I'll probably have a prototype back late next week.

Also interested to see how this turns out.  I'm especially interested in yours because I feel that the sides on the vortex prototype are too short.
