Maybe it's easier 3 speakers, a basic speaker directly for the STM32F (when using only the STM32F) and two good speakers, connected to the CM108H, when you use the EOMA68 (in this case the speaker of the STM32F would not work). ___ arm-netbook mailing list arm-netbook@lists.phcomp.co.uk http://lists.phcomp.co.uk/mailman/listinfo/arm-netbook Send large attachments to arm-netb...@files.phcomp.co.uk

If I use SSD2828, possibly I could never do it. In addition, FRIDA has given me a good screen (IPS, 4.5inch, 480x854, and RGB 18-bit) with resistive touch panel for a good price ($9.5). Perhaps the problem is that the MOQ is 5000 units, but if I want to do ZEOMA, that should be the minimum selling amount, as the costs of injection molds for plastic are also high.

Yes, our idea is to support all that. I still keep my GP32 and GP2X, I'm a fan of retro games and emulators.

I also prefer libre games, but the quality of these games are usually low (projects are very small and without money, I understand it and I'm not criticizing that games). My idea is similar to the idea of Luke, when you go to download a proprietary game, you will be warned that it is a proprietary game and its consequences. In my opinion, the problem of libre software is not the existence of proprietary software. The problem is that developers barely get economic benefits doing libre software.

My idea is that this freedom allows you to install what you want. For example, if you want, you can install a completely libre OS (like Parabola OS) or you can install a proprietary OS (like Windows, if there is a EOMA68 compatible in the future). On the other hand, my idea is to focus on a EOMA68-A20 with GNU/Linux OS (Debian perhaps?). Would be sent without any proprietary software. When you turn on it (first time), the OS will ask if you want to download the proprietary drivers for the GPU and if you want to activate the repository with proprietary software (such as proprietary games or emulators). I would also like to offer a EOMA68-A20 card with Parabola OS and other with Android OS.

[Arm-netbook] Block Diagram - ZEOMA - Handheld Games Console
Hello everyone. I suppose many of you know the handheld games console project based on EOMA68 (the provisional name is ZEOMA). The website (it is outdated (the images are also outdated), when the project is more advanced I'll update) (thanks to Peter Bouda) is: http://www.ubrew.it/ The features of the console are: - 4.5 inch 480x854 IPS screen. - Resistive touch panel. - DPad + A B X Y buttons + R button + L button + 2 Analog triggers + 2 Analog Joystick (with push button) + Start + Select + Home + Vol +/- + 2 extra buttons. - 4000 mAh battery. - Stereo. - MicroSD slot. - USB 2.0 Host. - MicroUSB (for charging). - STM32F072 for controls. - AR9271 WIFI. I have done a small block diagram you can see here: http://george.the-petries.co.uk/shared-write-access/eoma/Block%20Diagram%20ZEOMA/Block%20Diagram%20Console%202.0.jpg I have placed the datasheets of the components here: http://george.the-petries.co.uk/shared-write-access/eoma/Datasheets%20ZEOMA/ I have no prior experience designing schematics and PCB, but I will try to do my best. If I have any questions, I will ask you. I will publish all the schematics and PCB under GPLv3+. If anyone have any suggestions or improvement, I appreciate it. Thanks to Luke for all his help.

As you can see on the web, there is a design of the case of the console, however, this design is obsolete. I have no idea about design. Javier is who is doing the design of the case. He is very busy, but is working on it in their little free time. When he has done the design of the case, I will try to do the design of the PCB (with the help of Luke). Then we will have to make changes in the case and the PCB so that everything fits. Peter has made the website. I think he also wanted to make the code of the STM32F to make the controls works. I hope that if everything goes well, in the future Peter can help us in this task.

From the comments, I see that people think that Allwinner A20 is less powerful and more expensive than Raspberry 3. There is another who says to launch an EOMA-68 with an Atom (or CoreM). I suppose CoreM is not possible by high consumption. I think that people are not very concerned that Intel, or Windows, or NSA spy on them. They prefer a very powerful processor, although it is not free and spy on them. Usually people think they do nothing illegal with their computers, so people do not care that others spy on them.

Re: [Arm-netbook] crowdfunding page is live
Good luck, Luke! If the project is oriented to any public, perhaps I would do it more user-friendly. Perhaps it may be interesting to add a video like this: https://www.youtube.com/watch?v=jNR4zKqa6vI in the campaign but simpler. For example, put the EOMA-68, turn on, and run the graphical interface. Is there any possibility of an EOMA-68 A20 with Android or RemixOS? Perhaps for the general public it is more friendly/well-know than GNU/Linux. It would also be interesting to put sketches or drawings (more user-friendly) explaining the EOMA-68 concept. Perhaps it can be also interesting set goals (if given money is enough). For example, develop an EOMA-68 with Intel x86 with Windows and/or GNU/Linux if it is possible. ___ arm-netbook mailing list arm-netbook@lists.phcomp.co.uk http://lists.phcomp.co.uk/mailman/listinfo/arm-netbook Send large attachments to arm-netb...@files.phcomp.co.uk

The problem is that if you sell a few units will not have money to make more EOMA-68 (or devices) and will also be difficult to attract more investors. For example, Aaron sold slow and left the project. And in addition to paying the hardware, you have to pay salaries for people who develop software, advertising, and so on. So you need a lot of money. I guess you maybe think the community develop the software, but if you sell little units, it is difficult to attract the scene. For example, only devices that sell a lot like Raspberry have a good scene. > > > Perhaps it would be interesting to establish requirements for > > software and minimum hardware requirements as did 96boards. > > no. absolutely not. ok, clarification: the standard defines the > minimum hardware requirements, in terms of what interfaces MUST be > provided (even if they're lower speed). > > but software-wise: how can you define minimum software requirements > for a pass-through card? you can't. how can you define minimum > software requirements for an FPGA-based card? you can't. > > the whole point of the exercise is that there should be a *range* of > CPU Cards. i've discovered a $3.50 SoC from Ingenic that has 128mb of > built-in RAM. it's possible to create a 2-layer PCB based around it. > total BOM could well be around the $8 mark. > > ... should i define "minimum software requirements" that exclude the > possibility of creating such a low-cost CPU Card? hell no!! > > now, if that $3.50 SoC happened not to have the required SD/MMC > interface, or happened not to have 18-pin RGB/TTL which could do > 1366x768, or anything else, *then* it automatically gets excluded. I understand what you say. I mean that much variety can confuse non-expert people. For example, a classification. Can anyone buy an EOMA-68 destined for a router and put it in a laptop? Not now.

I remember when EOMA-68 would be sold in stores and you could put it on any kind of device. It was a very good idea, but very difficult to do (at least without the money of a big company). The problem is that people will be reluctant to buy a computer with Allwinner A20. Even the people will be reluctant to buy a computer without Windows or Linux (x86).
