I like the concept but don't like the hardware.
The processor is slow and the peripherals are a joke.
The laptop case has only one Micro SD-Slot and 3xUSB 2.0 (2 are internal).
If they would have used better hardware it might be a lot more interesting for me.
hiya askarus, thanks for replying - i answer about the peripherals in some detail in
http://rhombus-tech.net/crowdsupply/#questions, "I'm missing Ethernet and SATA on EOMA68, what about power consumption?". one correction: there's 2 Micro-SD card slots (one on the computer card, one on each of the laptop and the micro-desktop housings).
basically it's about what one person (me) can design and make on a *reasonable* budget (around $30k over 18 months) that can *reasonably* be claimed to be Eco-Conscious as a result. you can in no way claim that a design is eco-conscious if you spent $0.25m or above on it, can you?
by sticking to a 15 Watt budget i was able to use a bq24193 *single-cell* charger IC as opposed to having a much more complex hardware casework design housing a dual, triple or quadruple-cell battery, as well as having fans, metal and heatsinks to cope with a 20 to 25 Watt budget, which creates a mass compounding "cascade" effect. all that's gone with a simple single-cell charger IC.
if the laptop were to have even *one* extra USB port, it would need to be added by way of an extra 4-port USB Hub (more components), but worse than that it would take the laptop over the 15 Watt budget (2.5W per USB port). that would mean going into dual-cell territory as well as heat-sinks and fans, now you're into mechanical failure territory as well as cleaning issues down the line.
... start to make sense?
regarding the processor: it's efficient! for what it is it's damn good, and it can definitely be said to be "Good Enough" as in the whole "Good Enough Computing" thing - more on this in the white paper on ecocomputing that i wrote,
http://rhombus-tech.net/whitepapers/ecocomputing_07sep2015/
but it's missing the point of upgradeability to say that the processor's slow: you can *ALWAYS UPGRADE LATER*. that's the whole point of the exercise. pop out the old Computer Card, put in a new one - $50 to upgrade instead of $300+ and throwing the old laptop into landfill.
also, if you know of any faster processors that are available, that you would like to see put into EOMA68 form-factor, PLEASE TELL ME! i am looking for more to put on the roadmap because i am committed to this project for the next 10 years. but, let me give you a run-down of some of the ones that i've evaluated already, here we go:
- Mediatek SoCs: GPL-violating. Require NDAs. Fairphones got into seriously embarrassing trouble over selling a product that they couldn't provide people security updates over. what's the point of having an eco-conscious product if it has to go into landfill because it's dangerous for its end-users security and privacy??
- Freescale's iMX6: too costly ($36 for the quad-core!!) and it's an older 40nm design using ARM Cortex A9s that runs at around 4.5 watts (excluding PMIC and memory which are about another 1.5 watts), plus start-up requires something mad like 4 amps (!) EOMA68 has a hard limit of 5 watts, so as to not need fans or special heat-sinks.
- Texas Instruments OMAP4 series: Cartelled. Requires NDAs. If you're ordering a million and above you can gain access to it. Below that you have to be "evaluated" or referred to companies that will charge $0.25m and above for "design" work.
- Texas Instruments AM series (that's in the various Beagleboards): not good enough. 1ghz Cortex A8 is lower performance than the A20. They're also massively expensive for what they offer. And they use PowerVR graphics which is just... don't do it.
- RockChip: GPL-violating. Require GPL-violating NDAs. Require $100k "BSP" fees. There is however one person who managed to get round these problems by paying *only* $5k - Tom Cubie. Tom's team designed the Radxa Rock and it has full PCB and CAD files available for the Quad-Core RK3188. It doesn't have HDMI output, but it is at least a quad-core 32-bit SoC and i will be looking at this one, next.
- AMLogic: GPL-violating DESPITE BEING A USA-BASED COMPANY NOW. AMLogic cost me a large customer by embarrassing me due to their blatant GPL violations. I will never deal with them ever again.
- Qualcomm: HAHAhahahahaha https://news.slashdot.org/story/16/...o-guide-to-crack-android-full-disk-encryption AAAAhahahahaha https://hardware.slashdot.org/story/15/12/08/214239/qualcomm-faces-antitrust-charges-in-europe
- Actions Semi: can't get in touch with them (no response)
- Intel: Require NDAs. No BSPs. And, to cap it all, they just shut down their Smartphone and Tablet division, terminating the production of things like the Z37xx series which were used in those compute-stick PCs (that were 10 to 15 watt anyway!!!). Basically Intel's had it, but it will take a while for them to notice because they have such a large amount of cash reserves. also their SoCs are $21 which goes a long way to explaining why they shut down the division.
- RISC-V (aka LowRISC): nice idea, but the devil is in the *interfaces* not the *cpu type*. they don't really know how to make a good SoC
- Broadcom: hypocritical beyond belief. Telling kids that they can educate themselves so far but NO FURTHER because you may run ARM code no problem but if you want to view MP4-encoded media you have to PAY the "REASONABLE" fee of $2.50, what kind of message does that send to kids? broadcom is a greedy company that's only interested in profit.
- NVidia: the Tegra series is around 10-15 watts peak. The GPU requires something like EIGHT AMPS. there's no way that's going into a 5 watt (absolute max) computer card. Plus they won't let individuals at the BSPs (board support packages).
... did i miss anybody out?
serious question although it's asked tongue-in-cheek - i really *do* need to know if, amongst this dog's-dinner catalogue of endemic industry-wide failures to Get With The Programme, there is even a glimmer of hope!
but does this give you some idea as to why i'm using the A20 for the first Computer Card? it's $7. not $21: $7. not $36: $7. we've bludgeoned Allwinner to give us the source code. it's well-supported now. it works, and it's extremely efficient. Even FreeBSD supports it for goodness sake!
https://wiki.freebsd.org/FreeBSD/arm/Allwinner. Fedora supports it, Centos 7 supports it, Debian supports it, ArchLinux supports it, Parabola GNU-Linux/Libre supports it - even L4Linux and L4Android run on it - that's a Micro-kernel based real-time OS which most people have never heard of - what more do you want??
anyway - that should give you some idea of what's been involved. i *really have* thought about this a lot - it's been five years after all - i've very carefully evaluated both the standard and the available SoCs, and threaded a path that nobody else has noticed, to bring you a pretty awesome concept, making it easier for people to make their own computers, repair them, upgrade them and much more. any questions let me know. and please, i really meant it about the SoCs - i *need* more to evaluate!

@onpon4:
Since I agree with WizardStan in all points I will spare you a lengthy answer.
I'm not saying, you shouldn't buy the product. I'm just saying, if you care for FLOSS you should be aware that it contains components that were created by violating the very essence of what FLOSS is about. And a RYF certificate would harm that awareness imo.
sulu: thank you for pointing this out. in my earlier reply (i'm just catching up here) i point out that there really isn't a lot of choice. i'm in touch with Allwinner, i have been for five years, and i can tell you that they're KEENLY aware of the harm to their reputation. but we have to be realistic. think about this: the computer you're using, is it entirely spyware-free? it's an intel or an AMD post 2009 or post 2013 respectively, right? so it's got that "remote management" feature, right? so should you boycott intel because of that? and is it okay to criticise one company writing the message from another company's privacy-violating device?
my point is: we have to be realistic and make use of what we've got as a stepping-stone to work TOWARDS what we want. my goal is to get to the point where i see a mass-volume FSF-Endorseable processor being brought into existence. i don't mind how that's done, but if nobody else tackles it I CERTAINLY WILL. i'm taking steps on that path already, starting with this project and pursuing other avenues at the same time. one of those efforts was several years ago, with this:
https://tech.slashdot.org/story/12/12/04/1748232/toward-an-fsf-endorsable-embedded-processor
when the A10 came out (and was then upgraded to the A20) i was the person who, behind the scenes, worked indirectly to get the source code out of allwinner. since then, the A20 has become one of the most widely-supported SoCs from a china-based company ever. even freebsd, l4linux and l4android can run on it. very few people have even *heard* of the l4ka microkernel project!
so, at least there aren't any GPL-violating blobs *now* in the A20, and we have the opportunity to talk to them - with some pointed words - about how to proceed. the VP is tearing his hair out, btw. he knows that his neck is on the line, legally and ethically. But he's dealing with a situation where there are multiple investors who have carved out their own "enclaves", they're competing *INTERNALLY* and he needs some serious help to get them in order. so i will be going over to help advise them. but i CAN'T DO THAT UNLESS THIS PROJECT IS FUNDED.
... start to see what's going on?
would you rather make a stand *against* something (by boycotting them for example) or would you prefer to show them that there's a better way?
example: pine64 should never have allowed Allwinner to get away with saying that the A64 boot loader is "proprietary" and has to be kept "secret". they should have said, "well if you're going to commit GPL violations and expect us to sell copyright-illegal products that on import to the USA could risk being impounded at customs and destroyed without recourse to insurance because it's a criminal act, we're going to refund everybody's money". THAT would have got Allwinner's attention. but they didn't do that, did they?
any questions please ask. this is a *genuinely* libre project for the hardware, software and discussion. there's nothing to hide, and nothing to be gained by secrecy.

Except that the whole point of the RYF certification is to promote The FSF's ideological purism.
-Neelix
NO.
i didn't really get it - i knew intuitively that there was a point but couldn't explain it well - until chris encouraged me to apply for RYF Certification on the Libre Tea Computer Card. chris' business model is basically "plug it it, it'll work". if you've ever upgraded a computer that has a non-free proprietary firmware blob for the WIFI, you'll be familiar with the concept of being DISCONNECTED in the middle of the upgrade because the version of the OS is now incompatible with the proprietary firmware, and now you're screwed. *this* is what chris makes money doing: he researches the hardware so that YOU DON'T HAVE TO (and is actively involved in getting firmware released including full sources from atheros for USB-WIFI 802.11n chipsets for example - see
https://www.fsf.org/news/ryf-certification-thinkpenguin-usb-with-atheros-chip)
the business model is therefore based around hassle-free products that JUST WORK. he doesn't *get* all the "my computer stopped working because i upgraded it" problems, and has many loyal and grateful customers as a result who are more than happy to pay a bit more money because it's not worth their time to use the cheaper stuff that everyone else buys (and then throws away in landfill when it doesn't work).
the point is: it's ***NOT*** about quotes ideology, it *REALLY IS* about real-world practical products.
when we applied for RYF Certification, Josh Gay explained to us that the problem with e.g. Debian is that the average end-user could "blindly wander" into this non-free "pain" world where hardware could fail (or spy on you) *WITHOUT WARNING THEM*. in other words, right there in synaptics package manager, there's a check-box "non-free". Debian doesn't give you *any* warning about the consequences of simply naively clicking that checkbox.
*this* is what the work of the FSF is about. it's *not* quotes ideology quotes religion quotes any-other-bullshit-you-want-to-make-up quotes
does that make sense?
so the eco-laptop is based around that same principle. EOMA68's tag-line is even "Just Plug It In: It Will Work". there's a whole stack of other benefits as well.
