About, the rk processor.
by zap 22 Apr '17

22 Apr '17

something interesting I saw is that in the update picking a processor, it shows rk3188 as the rockchip processor you were going to reverse engineer. on the other hand, your rhombus-tech link shows that your looking at rk3288? Not to be annoying constantly, but I am curious are you looking at one or both? I appolgize if there is something I may have missed.

System 76 - Entering Phase 3
by Mike Leimon 21 Apr '17

Lyberta: > Couple of points that got my attention. They say Linux instead of > GNU/Linux. Open source instead of Free/Libre Software. They also > mentioned Ubuntu. This was enough to me to stop having any respect for > them. At least based on that post. While I understand what you are saying I don't see how having one of the most Linux friendly laptop manufacturers making a laptop based on the EOMA68 standard would be a bad idea. Let's say hypothetically, they decided to make the most awesome modular EOMA68 laptop possible, dual usb-c 3.1 and the works. Even if they did ship the system with a CPU card that was running Ubuntu on it, the whole EOMA68 standard works on the premise that if you can plug it in, it will work. Therefore, couldn't you just swap out out the CPU card and put any other compatible EOMA68 CPU card in there to enjoy the benefits of a well designed laptop and run your preferred distro instead? I understand that Ubuntu isn't your distro of choice (it isn't mine either) however, I think that there aren't many Linux friendly computing companies out there, let alone those that don't sell computers running anything other than Linux. I think that it is certainly important to have principles and to stick to them when possible however, when there seems to be as much common ground between what we want to accomplish and what they want to accomplish I am thinking it might be better to at least try working together than to hunt around for reasons to be divisive. Allan Mwenda: > Well i dunno, system76 would want to make the fastest card not necessarily the freest. I'm not so sure about this. I get the impression from reading some of their blogs and whatnot that they spend quite a bit of time and effort vetting the particular components they are putting into their systems to guarantee compatibility with their Linux distribution of choice. So while I do think they put some degree of importance into making sure that their systems have good performance, I do think they are aware of what having upstream driver support means for system components. I would agree that they would probably want to get the best performance out of a CPU card that they could however, I don't think that they would be too keen to do so at the cost of selecting a chip that didn't have some degree of upstream support. l: > i sort-of thought about this overnight, and i think you're right, > allan. the hardware they're selling is typically mid to high-end x86 > hardware [plus yes they talk about ubuntu] something like EOMA200 > would be a much better bet... but then so would many of the other > (industrial) modular standards for their needs. I suppose I still don't see the harm in bringing the EOMA68 concept up to them. The worst they could say is that they aren't interested. However, they could potentially be a pretty good ally. Also, I did notice that in the past few months they added a 96 core arm server to their lineup: https://system76.com/servers/starling Which means to me that they aren't completely wedded to solely x86 hardware. Even with their tendency to build higher end laptops and systems I think that an EOMA68 based laptop could easily exist within their line-up as an upgradable chromebook alternative (something priced in the $250-500 range). That would allow them to test the EOMA68 waters while at the same time allow them to build on and expand their higher-end line of x86 systems as well. I guess all I am trying to say is, that we won't know what a person or a company will do until we ask the question.

The R/Evolution... will not be Televised

There will be no binary blobs to spy on you, no nagware to pry your money from you, or a rootkit to pre-fit, like the BMG baloney that harmed the modern Army: CDs played in secret bases: Classified files sent to Sony.

The fish borrowed from Wenqing Yan's Fisheye Placebo. I'm sure it's modified enough to be fair use, but contacting them might be a good idea.

Personally, I like the super weird Linux problems. Can I have one of those malfunctioning alpha boards to try to figure out what's going on? I grant you that I've never worked on something quite this low level before, so I won't be solving it any time soon, but it would be worth looking into just so that we don't have this problem again (yes, I would like to learn how to create SBCs).

Fwd: Eurocircuits NEWS - Fantastic Q1-2017
by Luke Kenneth Casson Leighton 18 Apr '17

18 Apr '17

i don't normally like/forward this kind of stuff but just as a reminder, the shiny PCBs i did of the laptop were from this company. the pricing for the (very specific!) budget-end PCBs with 12mil vias, 10mil tracks and clearance and no green colouring was really *really* low cost, for europe: i was very surprised. also i was extremely impressed with the online viewer / gerber checker, it took a ton of hassle out of what would otherwise meant a manual process for them, which more than certainly is one of the reasons why they're affordable. l. --- crowd-funded eco-conscious hardware: https://www.crowdsupply.com/eoma68 ---------- Forwarded message ---------- From: Eurocircuits <euro(a)eurocircuits.com> Date: Tue, Apr 18, 2017 at 9:28 AM Subject: Eurocircuits NEWS - Fantastic Q1-2017 To: Luke <luke.leighton(a)gmail.com> PCB services <http://relay.eurocircuits.com/sendy/l/sVzVSf8nL8whQSbMX05zfA/NGzaHKIfCdeyt4…> | eC-Solutions <http://relay.eurocircuits.com/sendy/l/sVzVSf8nL8whQSbMX05zfA/iVQmtsRh7639Jh…> To: luke.leighton(a)gmail.com, 75 Katwijkstraat, 2585VM Den Haag, Netherlands Dear Luke Leighton Eurocircuits NEWS - Fantastic 1st quarter of 2017 The New Year 2017 took a high flight right from the start.

ZeroPhone

https://hackaday.io/project/19035-zerophone-a-raspberry-pi-smartphone Not exactly a netbook, but this looks like an interesting project. How much work would it take to create something like this using EOMA68? I know I would be interested in a device like that.

microdesktop case, laptop pcb1 and pcb2, etc.
by Luke Kenneth Casson Leighton 16 Apr '17

16 Apr '17

https://www.crowdsupply.com/eoma68/micro-desktop/updates/taiwan-micro-deskt… ok so i'm almost ready to send the laptop pcb1 and pcb4 off for prototyping, this gets about 20% the way towards getting the laptop done, but also is planned to be the basis of a new housing (an all-in-one PC) where sharing the exact same main PCB as in the laptop will cut costs of production of both. mark (van de borre): about the casework i've sent the DXF files off to a china prototyping company just so i can get something quickly. i don't expect them to be perfect first time, and to have do do another iteration. i'll want to do one last full systems test then the microdsktop v1.7 including casework can go into production. i haven't worked out if i have to do 2,000 of the corner pieces as 3D-printed or to get them injection-molded, at 2,000 pieces it *might* be worth doing as injection-molding. btw if anyone would like to see the gerber files for the three latest pcbs, they're here: http://hands.com/~lkcl/eoma/laptop_15in/pcb1/laptop_15in_pcb1_cam/ http://hands.com/~lkcl/eoma/laptop_15in/pcb4/laptop_15in_powerboard/ http://hands.com/~lkcl/eoma/microdesktop/eoma68_microdesktop_cam/ l. --- crowd-funded eco-conscious hardware: https://www.crowdsupply.com/eoma68
