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

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

libre laptop 3d print run 90% done
by Luke Kenneth Casson Leighton 18 Jan '16

18 Jan '16

holy cow there are *twenty five* separate parts in the laptop's casework. that's just nuts. if someone had said to me, "yeah you're gonna be making a 3d printed laptop, you'll need to do it in 25 separate parts" i would have said, "naah, you're having a laugh - surely it doesn't have to be that complex" which in the past has been my cue to run like hell from any project whenever someone uses the phrase "surely it doesn't neeeeeed to be as complex as alll thaaaat"... :) anyway i'm nearly done - i just have the touchpanel holder to redo, and the battery, pcb1 and keyboard tray supports that run off of it. the parts are all trimmed / adjusted (some details in the join points are just too small to be able to 3d-print accurately with filament), so i should be able to begin assembly in a day or so. fuuun. l. --- crowd-funded eco-conscious hardware: https://www.crowdsupply.com/eoma68

laptop casework, jz4775 cpu card, fosdem 2016
by Luke Kenneth Casson Leighton 15 Jan '16

15 Jan '16

hi folks, right. i've moved on to re-printing the 3d casework of the laptop, most of that will be in higher-temperature ABS. i'm about 50% the way through that, so another 2-3 days and i'll have an assembled prototype. some bamboo 1.5mm plywood panels are arriving from a U.S. supplier (the only one in the world that sells online 1.5mm bamboo!) are arriving shortly. the jz4775 cpu card, it turns out that digikey sent the wrong PMIC. bizarre story: the ACT8600-QJ162-T became popular in the past few months because of a smartwatch that was developed in china using the ingenic jz4775 reference design. so the formerly popular ACT8600-QJ601-T suddenly became UNpopular, leaving the world's last remaining supplier as being digikey. so, that's a china-made PMIC, which got shipped to the U.S. (customs-charge), got shipped back to china (customs-charges), then provided by the agent to the factory, then the factory put it on the PCB, then they sent that to me (customs charges)... and then it turns out to be the wrong f*****g IC. naturally it took a whole lot of shouting at digikey to get them to do a full audit of the stock of ACT8600-QJ601-T PMICs, but i've placed an order for replacements - to be sent directly to me - and will be putting those on when they arrive. also, only 1 out of the 6 PCBs happened to _not_ have solder-bridges under the DDR3 RAM ICs, so i've ordered some replacement DDR3 RAM and will be having a go at putting on 78-pin BGAs with the IRDA solder station. it'll be fun to try. ok.... correction: it'll be fun to succeed. also even though it's short notice i'm looking to go to fosdem 2016 because i happen to be in den haag at the moment, it's only a train ride to brussels after all. i'll be bringing along the completed laptop prototype if anybody would like to see it. l. --- crowd-funded eco-conscious hardware: https://www.crowdsupply.com/eoma68
