I've been playing with my dad's Onion Omega2+ this holiday period.
I've been so enthusiastic about the possibilities he's offered to give me one of the Onions, a dock, and a couple of Expansions and components so I can make more projects at home :) :) :)
I'm putting the finishing touches on a project inspired by your Crypto-monitor one, with it's own OLED display showing the price of SmartCash, Steem and Ethereum.
I really love the possibilities available with SBCs; in particular, the low cost for a ridiculous amount of computing power that will fit in a pocket is amazing. Anyone and everyone can afford a tiny little computer that they can experiment with all kinds of over-the-top programming on. It's great.
I was talking to a guy at the barbershop just a couple of days ago who was thinking about getting one of the new Samsung phones with a built-in projector for something like $600, and he looked a little perturbed when I asked him what he was actually going to use it for. And then I pointed out that he could have a Raspberry Pi, a portable projector, a decent keyboard, a small TV with HDMI interface, a nice-looking case, and still have $400 to get totally wasted on the next night – while still having enough computing power to hook up to TVs in hotel rooms or whatever mobile lifestyle you've got going on.
I look forward to hearing more about your experimentation with the Onion, though sad to say I am not the guy who is behind of the crypto-monitor SBC console. I believe that's @makerhacks . :)
That's actually a really good concern, and something I had to give a moment's thought to.
See, there's no hole in the bottom underneath the legs. I considered it, but it just seemed like making something of that order would be inviting some dimensionality problems when you went to line up the edge. It would be very unforgiving. And I may could have gotten around that with a sort of beveled lip, but I couldn't come up with a solution that I really felt happy with.
Instead, all the airflow is going to have to come from the sides. There are some really big openings in the sides – so that's not a huge burden, but it was a mild concern. Likewise, there are no openings in the top because of the way that the ports worked out.
If I were going back to make a second pass at this, I might really wrestle with some porting in the bottom, just to try and get a little bit of airflow coming in through those gaps at the ends of the legs, and maybe just a little bit of venting on the very top – even though there really is a lot of material to work with.
I almost feel like it would be more effective, if you really cared about excellent cooling, and weren't looking to go all the way to putting a 20 mm or 40 mm fan on the case – which could be done – to have the bottom plate CNC'd out of some aluminum and simply expect to heatsink through the PBC. Along with some of the readily available passive heatsinks to go on the memory and CPU, that would probably do all that you ever need.
I try and over kill the cooling because in summer in Southern California it can reach triple digits just in the house. The heat sinks would be a nice addition!
Yeah, Atlanta isn't exactly the usual place we think of when "easily cooled computational platforms" come up. Unless it's right now, when it's 27°F outside.
You can get some really nice large heatsinks for the Raspberry Pi, but I haven't needed them quite yet. If anything needs extra cooling, it's the motion controllers on my 3D printer – those things can find a way to overheat at the worst possible time.
There is a YouTube channel I think I've mentioned before which has a whole series talking about various cooling options for Raspberry Pi's. If you haven't seen it, you really should. It's pretty amazing.
Thank you. I would have much preferred to be able to upload the video without it being an entirely separate post to the blockchain, but there you go. Totally worth doing the experiment.
Looks good !

Made a repo on Github and all (still need to find time to write an article about it here on Steemit XS) : https://github.com/bockp/onion-coinmarketcap-project

Darnit, sorry for the mistake @makerhacks XS
But in any case your projects are interesting too XD

Awesome job on the vertical case! thanks for sharing, i bet this one will have better air flow

And look pretty awesome.
