Let us assume you somehow are able to get the battery bank into the computer's cabinet. Let us say, you use an usb port on the usb battery bank to both charge the usb battery bank and power supply the pc card. In order to power the pc card, you would have an usb cable connecting the power bank and the pc card. I have no power banks. Looking around, it appears power banks have a port for getting charged and one for power supplying devices. In general, are you sure, you cannot charge a power bank and simultaneously have it power supplying a device? If the power bank can be charged and power supply a device simultaneously you would connect another usb cable from the charger which charges the power bank to the power bank. Else if the power bank gets empty, you would remove the usb cable connecting the power bank and the pc card. Then connect an usb cable from the charger of the power bank to the power bank. I suggest to use a https://www.att.com/chargers/att-42a-dual-usb-low-draw-universal-wall-charg… if you want to charge the power bank and turn on the pc card at the same time. One usb cable from the charger to the power bank. One usb cable form the charger to the pc card. > > Tor > > -- > Tor Chantara > http://www.fineartmarquetry.com/ > 808-828-1107 > GPG Key: 2BE1 426E 34EA D253 D583 9DE4 B866 0375 134B 48FB > *Be wary of unsigned emails* > Stop spying: http://www.resetthenet.org/ > > > > _______________________________________________ > arm-netbook mailing list arm-netbook(a)lists.phcomp.co.uk > http://lists.phcomp.co.uk/mailman/listinfo/arm-netbook > Send large attachments to arm-netbook(a)files.phcomp.co.uk

EOMA68 card news
by Nick Hardiman 12 Jun '17

12 Jun '17

Where should I look for news about EOMA68 card production? http://rhombus-tech.net/ home is out of date. https://www.crowdsupply.com/eoma68/micro-desktop/updates has May’s update about 3D printing, I guess for the micro-desktop and laptop. http://lists.phcomp.co.uk/pipermail/arm-netbook/ has plenty of threads, mainly kicking ideas around. Thanks, Nick

https://www.youtube.com/watch?v=zXwy65d_tu8 It was very informative. A lot of the technical matter I did not understand. Can you explain: 23.04 The 2 lowermost boxes? What is a stepper? What is fuse? 25.15 The 4 lowermost boxes? 27.35 It appears there is money. 31.21 Alex Bradbury has said, it is difficult to verify, you get the hardware, you were told, you would get. 46.31 I agree.

I have reflected on that. What I write now is not directed against you or your crowd funding. It is in general about crowd funding. It seems crowd funding is some form of workaround about buying an item. I have no knowledge about court decisions in this field. I could imagine due to consumer law, a court would rule it a common purchase.

I disagree. Firefly writes "open source hardware platform". I find my interpretation legitimate. You are not backing up your interpretation with arguments. My argument is, they say it is open source. Then everything has to be open source if no reservations are stated. > > it's a common enough mistake. > > > I have found no reservations about the mali gpu > > source code or the pcb cad files.

I do not believe playing nice with the manufacturers will show a great rate of successes. Rather if big numbers of people would coordinated act like I do, some impact might show. There is no reason to not try both path simultaneous. Some people play nice.

You have a tendency to magnify the impact of one persons actions. Do you actually believe, that me writing manufacturers and making demands, right or wrong demands, has any impact on the situation of libre software? Do you think acer in any way takes notice? No. If half a million people in a short period of time hammered acer with demands, then there might be some impact. Previously you told me, that putting pressure on manufacturers should be done. Then I discarded what you said. I have reached to another point of view. Maybe coordinated campaigns, which are not being done now, might show some results. It can mobilize libre software people.

intel pc card
by ronwirring＠Safe-mail.net 01 Jun '17

01 Jun '17

Intel has made a pc card. https://www.youtube.com/watch?v=jlBtqeNykEc Probably intel will allow only intel inside pc cards. Even more they will maybe build in mechanisms to stop peripheral electronics from accept non intel pc cards. If the intel pc card peripherals get a marked and they can be modified to run with lkcl's pc cards, that could be a gain for his pc cards.
