Re: New Case - Pi Flavours -

They will probably barely break even with that amount after paying up for the EDM work needed to make that many sharp corners and slants. The basic tooling costs would readily give 5-figure pricing even without the quite unconventional mold design required.

Re: Yet another bloody alu case

It's supposed to be heavy. Anything you don't need a crane for is too light and may fall off the table. This is a compromise as I still don't have a traverse crane in my living room. My wife doesn't want one there for some reason. Maybe if I get her a good enough chocolate box for christmas, the cas...

Yet another bloody alu case

So heres what I scrambled together this evening: http://i.imgur.com/Qqtygl.jpg http://i.imgur.com/Q6rq4l.jpg Still full of would haves, should haves and could haves (and a zeroing bummer) but it seems to work well for now. The second one will be glorious :roll: Those ports just seem to be slapped on...

Nice!
Now put a stainless steel, laser cut pi logo on top and get machining :)

Re: Coolblock extra's!

Hi there, Were you planning on using a slitting saw on the fins or going with a really small endmill? I've made some heatsinks for the thing too. The first one is pictured lower down in this thread: http://www.raspberrypi.org/phpBB3/viewtopic.php?f=29&t=5823 I just can't get the rpm out of my machin...

Re: Short Crust Case

Wow, this must be one of if not the nicest case I've seen. I bet it will cost some good money, though as there seem to be some additional steps with the manufacturing compared to purely molded, two part cases. Any chance of getting a look at the bottom side of the case? Namely, the SD card slot side...

Re: Minimal Mac Pro-esq case

It's a macally G-S350SUA 3.5" HDD case.
I've seen it on amazon and newegg for around 37-40 USD.

There are a lot of nice 3.5" HDD cases out there and a tray to fit a Pi and a 2.5" HDD in the space would be cool to have.

Re: Ram Heatsinks

That's actually just a mockup; it's not mounted at all. It will be mounted with screws from the top so one can use spacers under it to still be able to mount the board using the holes. It hits the audio jack so I can't even get it straight on and a few components on the board are higher than on the ...

Re: Ram Heatsinks

I'm seeing stall medium between the parts as the problem, not just the direct thermal transfer in air. Air will always be moving, although very little, when temperature differences are present in a system. Still, I'm not saying it's a bad idea, just that, at least for me, the controlled enough envir...

Re: Ram Heatsinks

You will not be able to cram in anything that isn't in a really miniature syringe into that space. Thermal paste isn't even such a good thermal conductor that this would even be worth the effort. Silicon based pastes have a k of somewhere around 0,5-0,8 which isn't anything to cheer for. As a compar...

Re: RPI goes hiking - rugged composite case

I got the Neutrik connectors today so I seem to have solutions both for bringing out SMA connectors for GPS and WiFi. They're not quite what I had hoped for, though. Somehow I had gotten the idea, that they could be locked in in some manner. Using these connectors give rise to an other problem too; ...

Re: RPI goes hiking - rugged composite case

Yes, I/O should be carried trough a screw-on type military connector, which is a investment one has to make. The "duct" in the middle is there just to fit one of these and to protect it against direct blows. USB and video are mainly secondary priorities for on-site diagnostics. A networking interfac...

RPI goes hiking - rugged composite case

Hi, I am working on a case for outdoor use on robots and to be worn on a backpack. I am considering using a composite top case with a large aluminium plate as a bottom lid, doubling up as a heatsink for the pi. The basic idea is to make something that resemles a military "manpack" / radio transceive...

Re: Aluminium case, Barch Designs?

Has anyone found a rugged case for robotics use with a high IP-class?
We are talking close to military field spec here but with some cheaper connectors.

I have my own CNC equipment but I wouldn't want to tie up time on machines dedicated to high volume work.
