The magnificent seven


I am afraid a bit about these gray-coated and silver-coated plastics. My 200LX is not coated at all and is made of quite friction-resistant plastic. However, after long time of putting it in and out of pouch every day its edges became visibly smoother and polished, loosing its brittle texture. Coated Pyra's casing may end similar way and unfortunately the solution there is to make plastic of the color as close to coating as possible to minimize wear visibility.
The friction wear is always the same: Increases with pressure and distance of slide, decreases with material hardness.
 
I think that is about thermal capacity. You flatten the peaks.
Yes, that is how a non-radiating heatsink works, and is a good fit for sporadic tasks maybe up to things like video transcoding (providing you don't batch convert a lot of long files), but games where you can tweak the settings to use as many resources as possible, and then play for extended periods - that's when throttling kicks in eventually.

Now this an efficient ARM core rather than an x86 chip which has needed a heatsink since it hit 16MHz or so, and significantly more efficient than the one in my Pandora (which could develop a detectable hot spot if stressed for long periods), but at the same time massively more powerful than that.

Whether we get any appreciable radiation and convection of heat away by heating the SD card cages remains to be shown, and likewise whether we get any appreciable extra boost time by using them as extra sinks. But that's the best we can get with the revision 1 PBCs and case, so to that extent we'll get what we get.

So exciting times await while we find out how far we can push this chip and for how long.

Plastic-enclosed SBCs always rely on connectors as heat sinks, because they allow radiation as well as natural convection of heat to the outside without heating the well-insulated case.
The most important thing for that to work is the thermal bond between the SoC and the connectors, which is normally done with the solder joints and (thermal) ground planes inside the PCB, but is not so easy with a separate CPU Board.

Besides that, almost all SoCs that support NEON or have a good GPU are able to overheat without a fan.
 
Have IV bags of oil in the fridge and whenever you expect lots of heat, you set up a drip for your Pyra.

Ok, paint it from inside. We will talk about stuck keys later.
The oil drip would help with that, too.
 
Guess there is a point to that silver solder anyhow…
The main point to tin/silver/copper solder is that old lead/tin alloy solder is outlawed by ROHS requirements in new builds of electronics since the mid 90s I think. It will get slightly hotter than old leaded copper without distorting or melting, but the addition of silver and copper is specified to melt at a lower point than more pure tin solders.

I guess what you wrote was more of a joke judging by the ellipsis, but it may be worth considering that actually the pure copper ground plane is going to be a better conductor of heat (as well as electricity) because it its valence electrons.
 
Obviously I was talking about "user" level plastic paints, not professional as you show. Anyway you still have the keyboard issue :). If 0,1mm of coating affected the correct functionality, guess what could happen if you apply a layer of paint (and as you know, because you seems to know a lo of plastic paint, 1 layer is not enough for a good paint).

The only way is to see if we can dye the clear/white case, if not, plastic paint is not a realistic solution (only if you want to have a dirty and unuseful pyra).


at 2:45 into this video Bill shows how to tint a clear visor using synthetic fabric dye.

this is the video on tint visors he referenced.
 
Well, the aluminium surrounds have the logos already cut out, so they won't help for a custom design, would they?
Yeah, well I'm still waiting for some lid parts from you, so i can run some tests to make custom aluminuim and Resin parts. The idea is to exchange the whole thing. so the really intresting part would be to have the Logoplate not glued into the lid.
I have now access to a makerspace with a CNC mill, which is able to mill aluminium, so some test parts of the lid (could be fails from the mold, as long as the logo part is in the correct measurement)

However, we should wait for news like Totoro does...

It's not been 2 months, and especially not 2 months (TM) since the last news update; this is it and it was posted almost two weeks ago on the Tuesday. I agree that feels a bit of a gap after the last news of prototype units booting and supposedly being sent out to prototype level developers, but as I said in the weekly thread, hopefully it just means he plans to do a video next and has been too busy to do that for the past 12 days.
 
Sorry for being a bit off topic:

Is there any plans to use the newly release Debian 9 "Stretch" instead of Debian 8 "Jesse" ?
It would be nice to have more up to date libraries and things ...
