The sincerest form of flattery
by Mike Leimon 17 Sep '16

17 Sep '16

I saw this link today and thought to myself that it looked awfully familiar.... http://liliputing.com/2016/09/closer-look-kangaroo-notebook-modular-pc-syst… While I am hoping their pilot program is successful (because modular and upgradeable laptops is a great idea), this whole implementation appears to be proprietary from top to bottom and without any concern for libre usage. I suppose the other positive aspect to this (assuming the product takes off for them) is that there will a larger … [View More]

EOMA68 Libre laptop PCB2

http://rhombus-tech.net/community_ideas/laptop_15in/news/EOMA68_Libre_15.6i… quick update, i had to go back to using the 640x480 camera as the casio camera belongs to chris. i look forward to making an EOMA68 camcorder. ironically it'll need a full processor actually inside the Housing (probably something like an allwinner R8) as it needs to be able to do full HD video encode *on-board*. not enough bandwidth to get videos out of USB2 otherwise. --- crowd-funded eco-conscious hardware: https://www.crowdsupply.com/eoma68

Briefly plugged EOMA68 on Hacker News

On an HN thread about disabling the Intel ME (management engine), someone mentioned Talos and Novena as backdoor-free alternatives. So I put in a good word for EOMA68. https://news.ycombinator.com/item?id=12489544 Matt

[libreplanet-discuss] EOMA68 and freedom in digital technology

sorry, i'm receiving this as digest mode, from libreplanet, and haven't been watching it (or the other lists cc'd). i'll try to recreate the cc set of lists, apologies in advance if this doesn't get through to all of them. also, please be aware that i'm leaving for HK in about 10 hours time and it's an extremely long flight, so i'll be offline for at least the next 2 days. also i'm adding arm-netbook (needs subscription) because i'd like to make people on that list aware of this discussion, … [View More]which appears to have been ongoing for some time. >> I disagree.

RAM
by Vincent Legoll 13 Sep '16

13 Sep '16

Hello, and apologies if this already has been talked about, I tried to find previous discussions on ML archives, elinux & rhombus sites. It looks like the DRAM will be standard DDR3, has low power DDR3 been studied ? Too expensive ? No available init code ? I ask because some other ARM boards differentiate themselves from the other one by using LPDDR3 and that has much better power consumption characteristics, and so do not heat as much. The regular DDR3 ones (in certain cases have a … [View More]

Housing idea: screenless laptop
by Matt Campbell 13 Sep '16

13 Sep '16

Hi, It occurred to me that for blind people, who use a screen reader such as Speakup or Orca, a laptop housing without the screen or the touchpad would be quite convenient. And if this housing used the same battery as the regular laptop housing, it would last longer because there's no screen. To the engineers on the list, how difficult would it be to modify the current laptop housing to remove the screen and touchpad? I suppose there are two ways to go about removing the touchpad: either … [View More]

how to use the stand-alone cables
by chadvellacott＠sasktel.net 13 Sep '16

13 Sep '16

Regarding the offerings on the page at "Crowd Supply"- To use one of the computer-cards as stand-alone, with the cable-set offered for that purpose, do I just- (1) buy "a smartphone / tablet 2A USB-OTG Charger (which is easily found at any store these days including Walmart or Asda’s)", (2) connect the 3-way cable to (a) that charger, (b) the computer-card, and (c) the HDMI-cable, (3) connect some HDMI-screen to (a) the computer-card and (b) the HDMI-cable? Where or how … [View More]

by "Resin" (versus "PLA"), is meant what? ABS?
by chadvellacott＠sasktel.net 13 Sep '16

13 Sep '16

Considering which "PFY" lap-top housing to choose. On the page on "Crowd Supply", for the "PFY" lap-top housings, most of the options involved "PLA", but one was rather "Resin". I imagine that by the former is meant "Polylactic acid" <https://en.wikipedia.org/wiki/PLA_polymer>. But that is listed under "Resin Identification Code" 7 <https://en.wikipedia.org/wiki/Resin_identification_code#History> so seems to itself be considered a kind of Resin. [Rats, an ambiguity.

"zombie" campaign
by chadvellacott＠sasktel.net 13 Sep '16

So, as mentioned in my list-message "Sorry to Luke (and others)", I have some questions. This message is just to give context for the questions. The questions are regarding the campaign on "Crowd Supply". I HAVE NOT YET SENT MY ORDER AND PAYMENT. But from a private reply from Luke (quoted next below), I guess that we have SOME more time. I will number the "e"mails of questions, as to priority for me deciding whether and what to back, with #1 as top priority for me. (This … [View More]
