As I was going back over my previous update on my visit to Shenzhen, it suddenly hit me: everything I've done over the past five years - the entire EOMA68 design ethos - is vindicated by this one visit to Huaqiang Road. Read the full update.
This update is about being in Shenzhen for the past few days, during their October National Holiday. In summary, I know now why it's been so damn difficult to get anything done from outside of China: it's the incredibly poor internet access. Read the full update.
Summary of the past ten days and updates on several threads. Read the full update.
We’re staying with a friend in Hong Kong as we oversee progress on the laptop's PCBs. The revised EOMA68-A20 was submitted for prototyping and may actually be ready within under ten days. Enquiries are still outstanding for tracking down a S5P6818 Reference Design. Read the full update.
Here’s an update on the past couple of eventful weeks. A plan of action (in development) has been started in a bugtracker, flights are booked to HK, we're doing the t-shirts before we leave, we dealt with the DDR3 RAM upgrade and sent it off for prototyping estimates, we sorted out revision 1.4 of the Microdesktop layout, and we spent an enormous and disproportionate amount of time dealing with Wikipedia. Read the full update.
The past week was an amazing rush, passing and exceeding the funding target with your help, and even now it's still climbing. Read the full update.
This update lays out the roadmap for the EOMA68 project and what the future holds for modular, eco-conscious, libre computing. Read the full update.
The Free Software Foundation (FSF) posted an article on August 10, 2016 entitled "Support the Libre Tea Computer Card, a candidate for Respects Your Freedom certification." Read the full update.
I asked David if he would write a guest update about his experiences of dealing with an older laptop. The complexity of the design contrasts greatly with that of the EOMA68 15.6" Laptop Housing. Read the full update.
Hello! I have three bits of news for you. Read the full update.
Albert, who only joined the arm-netbook mailing list a few short weeks ago, has been helping with the keyboard firmware. He's very kindly made a short video of the STM32F072 providing AZERTY (French) keyboard support, which he wrote. Read the full update.
After running the libreoffice, printing and web browsing updates with associated videos on Parabola-Arm GNU/Linux-libre, the performance was less than modest. In complete contrast, when running the exact same programs under Devuan, the difference in speed is staggering and so noticeable as to be worth doing a separate update. Read the full update.
People have been asking what the web browser performance is like on a $7 dual-core A20. Here's an honest appraisal and some tips. Read the full update.
We've added a geek-friendly T-Shirt to the options: this quick update covers the sizes and colours Read the full update.
I am delighted to be able to announce that the Cedrus fully-GPL-compliant accelerated video encode/decode libraries work out-of-the-box on the EOMA68-A20 Libre Tea Computer Card: 1920x1080 at 60fps (1080p60) works great, full-screen. As the CEDAR Reverse-engineering is an FSF High Priority Project this is a big deal. Read the full update.
We've just done a show on Free TalkLive here in Keene, NH, see the video from the studio. Read the full update.
We've been asked to demonstrate LibreOffice, Gimp and also took the opportunity to show printing (in this case using a networked HP Laserjet). Read the full update.
We asked on the mailing list if people could come up with examples where EOMA68 could be used by people with more computing experience to make it easier and less costly for them to support friends, family and clients. What we weren't expecting was an actual real-world scenario to occur during the campaign. Read the full update.
Lilyana and I are having great fun at the moment, crashing boats, submarines and satellites thanks to gcompris running on the Libre Tea Computer Card. Read the full update.
This is a quick - and very honest - demonstration of the Sugar OS of OLPC fame running on an EOMA68-A20 Computer Card. Read the full update.
Thanks to everyone's help we reached an important milestone yesterday evening: USD $50,000 from over 500 pledges. Read the full update.
We're adding two new OSs to the pre-installed option: Devuan and Fedora 24. These are now available (look right and scroll down), and we will be evaluating more OSs, including in particular SUGAR and FreeBSD. Read the full update.
One of the ideas for EOMA68 Cards that's been in the cards (pun intended) for some time is a Pass-through Card. The possibilities for this Card are really exciting, so we decided to add it during the campaign. Read the full update.
The EOMA68-A20 Computer Card has been using the older u-boot and sunxi-3.4 kernels for some time. This update shows a recent mainline u-boot (2016.07) and a sunxi-next near-mainline 4.7.0-rc5 Linux kernel. Read the full update.
We're currently at Hope 2016 with Think Penguin here in New York, Seva Epsteyn kindly did a live video for us to show the computer card, laptop housing, and micro-desktop. Read the full update.
With Fedora 24, Debian, and Parabola already on the list, Devuan we felt was important addition to have, due to the "hassle-free" ethic inherent throughout this campaign. Read the full update.
In speaking with people on the mailing lists and various forums, we're getting a lot of questions from people new to the EOMA68 concept. After answering Nick's questions about how to set up ultra-low-power servers using EOMA68 Computer Cards, he had these kind words to say... Read the full update.
Over the years there's been quite a few innovative laptop projects out there, including from mass-volume suppliers: a bamboo laptop, a recycleable one, an engineer's laptop, and many more. In this update I'd like to go over them all as a way to distinguish the EOMA68 Laptop Housing, as well as illustrate how this project has learned from them all. Read the full update.
Fedora 24 is up and running on the EOMA68-A20 Computer Card! We have yet to pick a name for it (suggestions welcome) however it's still worthwhile letting people know about: a quick video demo is available. Read the full update.
I thought I'd share with you how amazed and delighted I am at some of the questions and debates that this project has raised. Read the full update.
Thanks to Albert for contacting us and agreeing to help out via arm-netbooks. He contacted me last week to ask if it the laptop would have AZERTY keyboard support. As this is a libre project, I explained to him the process, not realising that he was an embedded hardware engineer. Read the full update.
We've had a number of people, many of you electronics enthusiasts and makers, ask how to connect to the EOMA68 Computer Cards for use in your own electronics projects. We do have some GPIO pins on the Micro Desktop... Read the full update.
Thanks to Demon3D of the Reprap community we can show you a time-lapse video of one of the laptop's parts being 3D-printed. The video shows the back left base part, which, thanks to having internal arches that were modelled on those used in Gothic Cathedrals, is incredibly strong despite a wall thickness of only 1mm and an overall length of 160mm. Read the full update.
We've had a lot of people asking about alternative processors; a lot of suggestions on what we should be making available in EOMA68 form-factor, as well as quite a lot of criticism for only having a Dual-core ARM Cortex A7 1.2ghz. The list of checkboxes needed to be ticked for an ethical eco-conscious Computer Card is really quite long: no NDAs, full sources, no spying built into the hardware, reference designs available, datasheets, and much more, so we thought we'd take you through some of the top ones. We'll also put in some estimates for costs both in time and financial terms. Read the full update.
After ordering a slough of parts, including one of the obscurely-named On-the-Go Host-Charger cables which we finally found, we've been able to test and verify the two cables needed to turn any Computer Card into a standalone computer, without the need of either of the Micro Desktop or Laptop housings. We've added it as a pledge level to the campaign Read the full update.
We've had some people notice that there's no stickers, mugs, t-shirts and so on... Read the full update.
I thought it would be nice to do an assessment and give you some insights into how we came up with the pledge levels. The pledge levels have been based on a minimum order quantity (MOQ) of 250 units. Ordering PCBs and components is odd: there are fixed setup and teardown costs which don't change no matter how many PCBs you get made, and the components that are soldered to the PCBs can come in reels of 2,500 or trays of 100. Ordering a partial reel is so time-consuming and inconvenient it's just not worth it. All this basically means the smaller batch sizes are much more expensive per unit than larger batch sizes: ten times the cost is not uncommon. The problem is nobody would buy a $50 computer if it cost $500. That's where crowdfunding comes into its own. Read the full update.
While a Computer Card can certainly slot into the micro desktop and laptop housings, it can also be run on its own with the addition of a some basic cabling. Read the full update.
