EOMA68 integration in to MLAB modular system.
by Jakub Kákona 28 Feb '16

28 Feb '16

Hello all, I am coming to this forum trough that page: https://www.youmagine.com/designs/libre-hardware-licensed-parametric-laptop… <https://www.youmagine.com/designs/libre-hardware-licensed-parametric-laptop… Thanks> Thanks very much for this great work! I am interested in EOMA68 project for several years. Althought I am currently using the ODROID boards in my projects - one example is radio meteor detection station: http://wiki.mlab.cz/lib/exe/fetch.php?media=cs:designs:rmds:rmds02d_station… This is a typical candidate of electronic computing device which needs occasional hardware upgrade or rapid firmware and configuration change.. Therefore I looking forward for moment when we could integrate the EOMA68 cpu card in our modular system http://www.mlab.cz/ <http://www.mlab.cz/ and> and after that in to related designs which already exists. Therefore you can count on me if there were a group order of EOMA68 cards or an crowdfunding campaign. We have a long term electronics design experience and quite good contacts to other electronics manufacturers here in the Czech Republic. I would like to ask if there were some subtask which we could help with? If none, I will continue to work on related problems such as open-source battery management and effective solar charging system for portable devices. But the cooperative development will be the best solution because there are huge tasks which we need to overcome. Uniform 3D printable laptop is one of the things which could bring together the open-hardware design community. I expected it even in case of Novena laptop, but they go to the different direction focused on performance needed for hacking. Kaklik

eoma68 laptop casework progress

hi folks sorry been extremely busy. i've managed to work out some superb settings for the mendel90, it's currently operating at *200*mm/sec, with a layer height of 0.15mm, and the prints are coming out with smooth walls most of the time. i'm deeply impressed with the mendel90, now - it's only taken me 18 months (!!) to get the right settings. the bamboo plywood is in place, successfully - i put a diagonal cut on each edge, and a matching groove into each piece of 3d-printed plastic, only about 0.8mm depth (it's supposed to be 1.4mm but it prints out at less than that) - and the panels hold perfectly. not only that but they hold sufficiently well that i decided to use them for structural support on the screen edge. the screen hinge has proved particularly tricky: it's quite a small piece, taking a huge load because it contains the friction hinge. turns out that if i jam the bamboo panel into it (and its neighbouring pieces), the screen hinge stays still under load. i'd previously tried all sorts of tricks to get the screen hinge to "lock" into its neighbouring pieces and it wasn't working: the plywood does a really good job. am still making minor adjustments, chewing through PLA like it's no tomorrow, photos to follow, then they can be sent to crowdsupply. l. --- crowd-funded eco-conscious hardware: https://www.crowdsupply.com/eoma68

tp-link's response to the FCC's new WIFI rules
by Luke Kenneth Casson Leighton 20 Feb '16

http://slashdot.org/submission/5574003/tp-link-confirms-wifi-freedom-is-dea… any chance people could click "+" on the "submission" button on this? the FCC's screwed up - ignored comments from a bunch of experts - and gone ahead "oh nooo nooo problemmm, nooobody will just lock down the entire embedded OS" and of course that's exactly what TP-Link has done, because it's the easiest thing to do. this applies to embedded boards just as much. it's now a legal requirement to DRM-lock the *entire OS* - kernel, bootloader, OS - *everything* - on embedded boards that happen to have WIFI modules on them. l. --- crowd-funded eco-conscious hardware: https://www.crowdsupply.com/eoma68

libre laptop early kits: planning
by Luke Kenneth Casson Leighton 14 Feb '16

14 Feb '16

ok, so in about 2 months i'll be doing a SMALL production run - absolute maximum of 20 units - of the latest revision EOMA68-A20 CPU Cards as well as putting together some 2nd revision laptop kits. it *might* also be the case - i have to check how many - that we have a sponsor (a 3d-printer company) for printing out the casework parts, primarily because these are exceptionally challenging parts and the sponsor would like to show that the quality of their printers is up to the task (which it is). certainly i am pushing the limits of the mendel90 which is in essence a significantly-improved reprap, as it is. at this very early stage i don't want to go above 20 units just in case i have to do modifications by hand to the PCBs - which, if it becomes necessary won't be hard (with the 2-layer single-sided boards): i just don't want to have to spend that much time. now, i'm *estimating* that the kits will be around the $EUR 400 to $500 mark, if we _can_ get to 20 then it may be less than that. i also have another sponsor who is prepared to buy some kits to sell, so that the per-unit cost can come down - we just have to see, based on who'd be interested. so... who's interested? l. --- crowd-funded eco-conscious hardware: https://www.crowdsupply.com/eoma68

well um i'm here.. an entire week early :) long story, but having booked the train tickets and hostel, nobody actually told me i was on the wrong day because of two separate and unrelated pieces of confusion / misprints! i decided rather than go back home to simply stay a week, having brought everything - soldering-iron, ruler, pliers, scissors, laptop, the works - with me all this way. 15kg suit-holding bag on wheels.... and in my infinite wisdom i decided that it would be an interesting experience to come to belgium on skates. with a 15kg wheeled bag. so, anyway, i'll be volunteering for setup on the friday, i have the laptop to demo, am registered for a lightning talk on saturday morning, this might change if there's a full hour slot available (i'm on short-notice standby). it'll be fun. the http://2go4.be is pretty good, the no 71 bus goes straight to ULB, there's a walk each end of about 250 metres... am enjoying the accidental circumstances... l. --- crowd-funded eco-conscious hardware: https://www.crowdsupply.com/eoma68
