EOMA68 Libre laptop PCB2
by Luke Kenneth Casson Leighton 16 Sep '16

http://rhombus-tech.net/community_ideas/laptop_15in/news/EOMA68_Libre_15.6i… quick update, i had to go back to using the 640x480 camera as the casio camera belongs to chris. i look forward to making an EOMA68 camcorder. ironically it'll need a full processor actually inside the Housing (probably something like an allwinner R8) as it needs to be able to do full HD video encode *on-board*. not enough bandwidth to get videos out of USB2 otherwise. --- crowd-funded eco-conscious hardware: https://www.crowdsupply.com/eoma68

On an HN thread about disabling the Intel ME (management engine), someone mentioned Talos and Novena as backdoor-free alternatives. So I put in a good word for EOMA68. https://news.ycombinator.com/item?id=12489544 Matt

sorry, i'm receiving this as digest mode, from libreplanet, and haven't been watching it (or the other lists cc'd). i'll try to recreate the cc set of lists, apologies in advance if this doesn't get through to all of them. also, please be aware that i'm leaving for HK in about 10 hours time and it's an extremely long flight, so i'll be offline for at least the next 2 days. also i'm adding arm-netbook (needs subscription) because i'd like to make people on that list aware of this discussion, which appears to have been ongoing for some time. >> I disagree. There is simply nothing you can compare this project to. We >> are achieving results that can't be demonstrated via any other means. If >> we could get here some other way at a lower cost with the same long term >> impact I would have gone that route. > > See what Olimex has been doing for years then. you're aware that olimex operates as a criminal cartel, from shipping GPL-violating A10 bootloaders and kernels provided by Allwinner, back around 2011/2012? you're also aware that with the sole exception of the olimex laptop's PCBs the only thing that they provide is auto-generated PDFs *from* the schematics source code... not the actual schematics and certainly not the PCB design files? > They're also coming up with a laptop design. ... where they've taken off-the-shelf china-sourced (proprietary) casework: i started the GPLv3+ casework project for the EOMA68 15.6in laptop housing *two years* ago as a completely and fully libre project. you can verify that by looking at the git commit logs. tsvetan has caused a hell of a lot of trouble for the EOMA68 project and has sponged off of the resources of a *lot* of people. he truly doesn't understand the word "libre". at all. also, the A64's processor - which tsvetan is using for the olimex laptop - requires a proprietary early-bootloader. in fact, the first A64 SDK that came out was an absolute mess, comprising several GPL violations in both the early-bootloader, the u-boot source *and* the linux kernel. the SDK was even exclusively distributed over a chinese illegal filesharing network (this is an "official" released SDK from allwinner!) over a considerable period of time, pine64 and the sunxi community worked to eliminate as many of those GPL violations as they could, but Allwinner insisted on keeping the early-bootloader proprietary. so at present the A64 is classified as a "non-libre" processor. that it's the basis of the olimex laptop tells you everything you need to know. to tsevetan's credit he is doing his best as he understands it, but there's nobody taking him to task on the things that matter to software freedom. he's happy to take your money even if it means selling you product that requires proprietary software. he's *less* happy to then *invest* that money into helping solve the issues which create all the problems that go *with* proprietary software. now, whilst tsevtan is making money selling you hardware that requires non-free components to operate basic functions, i've put my foot down and said NO, i will NOT sell GPL-violating product. i don't care if that means it's harder to deliver ethical products, i'll deal with that on an ongoing basis, but here's the thing: it means i've established a reputation for setting some ethical rules *AND STUCK TO THEM*. > I agree that you went steps further than most before, but this is > incremental improvement, not something truly new and groundbreaking compared to > what existed before. hmmm, an interesting perspective, which i feel may be based on not being aware of the sheer overwhelming number of issues being tackled (all at once). yes it's "incremental improvement" but it's a MASSIVE stack of MULTIPLE "incremental improvements", all done at once. *nobody* has tried to do that before. not Dell, not Olimex, not IBM - *nobody*. for example you compare the EOMA68 Housing to the olimex laptop. the olimex laptop's casework is proprietary (the EOMA68 Housing's is GPLv3+ libre-licensed). so automatically you can see that it's nowhere near being a legitimate comparison. >> The issue is your looking at one thing.

RAM
by Vincent Legoll 13 Sep '16

13 Sep '16

Hello, and apologies if this already has been talked about, I tried to find previous discussions on ML archives, elinux & rhombus sites. It looks like the DRAM will be standard DDR3, has low power DDR3 been studied ? Too expensive ? No available init code ? I ask because some other ARM boards differentiate themselves from the other one by using LPDDR3 and that has much better power consumption characteristics, and so do not heat as much. The regular DDR3 ones (in certain cases have a heat problem and have to be down-clocked to operate properly whereas the LP ones don't... On the same subject of heat dissipation, some boards use a layer of the pcb just below the soc to act as a heat spreader by having a copper area that is not used for signals, and it looks like this is effective, because other boards that don't have it endure heat problems. I had a look at EOMA PCB pictures, but I lack knowledge to definitely tell if there is such a copper layer provisioned. Thanks And Luke, don't overwhelm yourself into burn out. -- Vincent Legoll

Housing idea: screenless laptop
by Matt Campbell 13 Sep '16

13 Sep '16

Hi, It occurred to me that for blind people, who use a screen reader such as Speakup or Orca, a laptop housing without the screen or the touchpad would be quite convenient. And if this housing used the same battery as the regular laptop housing, it would last longer because there's no screen. To the engineers on the list, how difficult would it be to modify the current laptop housing to remove the screen and touchpad? I suppose there are two ways to go about removing the touchpad: either it could just be replaced with empty space, or the keyboard could be moved to the front. In the latter case, how much smaller could the housing be made without removing anything inside (battery, space for a USB dongle, etc.)? Matt

how to use the stand-alone cables
by chadvellacott＠sasktel.net 13 Sep '16

13 Sep '16

Regarding the offerings on the page at "Crowd Supply"- To use one of the computer-cards as stand-alone, with the cable-set offered for that purpose, do I just- (1) buy "a smartphone / tablet 2A USB-OTG Charger (which is easily found at any store these days including Walmart or Asda’s)", (2) connect the 3-way cable to (a) that charger, (b) the computer-card, and (c) the HDMI-cable, (3) connect some HDMI-screen to (a) the computer-card and (b) the HDMI-cable? Where or how would I connect a key-board and a "mouse"? I do not remember reading anywhere that such could be directly connected to the "EOMA 68"-card, but perhaps I am forgetting something relevant about that standard. The "Intel Compute Stick" seems to use "Bluetooth" for those (https://en.wikipedia.org/wiki/Intel_Compute_Stick), and the "Chromebit" seems to add the possibility of "WiFi" (https://en.wikipedia.org/wiki/Chromebit), ... but how will Rhombus-Tech's stand-alone enable these peripherals? Eagerly, Chad. (:^)

by "Resin" (versus "PLA"), is meant what? ABS?
by chadvellacott＠sasktel.net 13 Sep '16

13 Sep '16

Considering which "PFY" lap-top housing to choose. On the page on "Crowd Supply", for the "PFY" lap-top housings, most of the options involved "PLA", but one was rather "Resin". I imagine that by the former is meant "Polylactic acid" <https://en.wikipedia.org/wiki/PLA_polymer>. But that is listed under "Resin Identification Code" 7 <https://en.wikipedia.org/wiki/Resin_identification_code#History> so seems to itself be considered a kind of Resin. [Rats, an ambiguity. (:^) ] So what is meant by "Resin", in the list of options? If the meaning is "ABS", then this comparison is relevant- <http://www.absplastic.eu/pla-vs-abs-plastic-pros-cons/> Ideally, I'd like something which is- (a) sturdy enough to let a clumsy adult use, and sturdy enough to gift to a child (even if the child is just starting to use a computer), (b) can be left in a hot car without deforming, (c) can be used in temperatures as cold as the parts can handle, without becoming brittle (any one for computing outside in fresh air, in winter?), (d) durable enough to last as long as the parts, (e) transparent, so that I can see the inner parts through the housing, (f) made from renewable materials, (g) safer during the 3D-printing. But I suspect that the "PLA"-option does not meet A to D as well as the "Resin / Black" does. I guess that then my decision is not so easy. Hoping to pre-"order" soon, Chad. (:^)

"zombie" campaign
by chadvellacott＠sasktel.net 13 Sep '16

13 Sep '16

So, as mentioned in my list-message "Sorry to Luke (and others)", I have some questions. This message is just to give context for the questions. The questions are regarding the campaign on "Crowd Supply". I HAVE NOT YET SENT MY ORDER AND PAYMENT. But from a private reply from Luke (quoted next below), I guess that we have SOME more time. I will number the "e"mails of questions, as to priority for me deciding whether and what to back, with #1 as top priority for me. (This is not to be pushy, just to inform you what can most help me personally.) (Actually, now I am thinking to buy the printed lap-top kit, plus the desk-top housing, plus the stand-alone, plus one or more libre-tea cards, plus the break-out board, plus the pass-through card.) (By the capitals, I did not mean to "shout". I just meant "emphasis". Do you prefer "emphasis" be marked not by capitals but rather *thus* or _thus_?) (Quotes below, might have minor changes, and might have additions enclosed by {}, and ~ for omissions.)

Clear and Translucent- so base-half is see-through, screen's half is "fogged"?
by chadvellacott＠sasktel.net 13 Sep '16

13 Sep '16

Considering which "PFY" lap-top housing to choose. One option listed was "PLA / Metallic Silver Base with Translucent Screen Assembly". One option listed was "PLA / Clear and Translucent". (a) So for the latter option, the base is the clear part, and the screen is the translucent part? (b) And by "Clear", is the meaning, "see-through", as in I could see the hard-ware components inside of the base, while typing at the lap-top? That'd be really nice, educational. (c) And by "Translucent", is the meaning, like privacy-glass and "frosted" bulbs and "fogged" glass? That sounds interesting. I am guessing that Translucent is offered because it looks nice or something. (d) But how so? What kind of a visual "effect" does the "Translucent" have that looks nice? Some of the answers might seem obvious enough to not even ask. But I like things to be really unambiguous, even if the cost involved is "only" 500.00 rather than 10,000.00 (;^). Hoping to pre-"order" soon, Chad. (:^)
