Fwd: Funding ideas
by Luke Kenneth Casson Leighton 15 Jul '19

15 Jul '19

---------- Forwarded message --------- Date: Sat, Jul 13, 2019 at 4:51 PM Subject: Funding ideas To: Luke Kenneth Casson Leighton <lkcl(a)lkcl.net> Hey. Sad to say I had little progress on my "Why EOMA for crypto" article/promo campaign but at least I have some ideas to share. 1. Education What is a good susbtance for education? Something open and available. You can't teach and study the making of computers on closed Intel hardware and software. You can use open platforms like OLPC or Minix but most of them have a drawback - they are either purely academic/educational, or unpopular/unsuccessful in the wild. With EOMA and Libre RISC you (as an educational institution) can have both: something that is open down to the bone and can be a great learning substance for studens, _and_ something that is a real commercial product in the wild. The idea is to grow partnerships with schools/unis/academia (and possibly win some grants). For EOMA there are potential strategic benefits - it will be very hard to kill something that generation(s) have studied in schools/unis. If your random geek neighbor can fix or upgrade your device I'd call it a win. 2. OSS funding platforms Recently I ran across some OSS funding movements emerging in the crypto space. One is called Gitcoin. It is a general bounty platform for funding open source. Recently they had quite a lot of overlap with Ethereum https://gitcoin.co/blog/radical-results-gitcoins-25k-match/ Another one is GitHub - they recently integrated a sponsorship system that allows to fund individual developers. Repository admins can now increase visibility of funding options for their open source projects via the FUNDING.yml file, which currently supports GitHub Sponsorship, Patreon, Open Collective, Ko-Fi, Tidelift, Community Bridge, as well as custom URLs. https://help.github.com/en/categories/supporting-the-open-source-community-… https://help.github.com/en/articles/displaying-a-sponsor-button-in-your-rep… I'm sure there are other such platforms. The common thing is they all look how to match donors with workers. 3. Grants from specific crypto treasuries Zcash Foundation grants is just one example. This is obviously not general and is Zcash specific. Since the focus is Zcash, I guess they might need clear understanding what will Zcash gain - in our case this is a non backdoored, fully auditable, cheap device that allows one to run a light crypto wallet and that you can easily carry around. Example funded initiative: https://zengo.com/zcash-foundation-funds-research-project-by-kzen/ The above idea applies to any cryptocommunity that might be interested in cheap and trusted computing device. It also applies to Decred - we now have a platform where anybody can pitch an idea to stakeholders, run a vote and possibly get funded. Like 10 or 20 initiatives have already been funded. They were all specific to Decred, but I hope that the understanding of importance of hardware will grow and stakeholders would approve some joint funding for decent projects like EOMA. 4. Meta: reuse existing research The problem is not new. This guide has collected various approaches and case studies: https://github.com/nayafia/lemonade-stand Feel free to share this to anyone who might advance these ideas.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Dear luke, list, As both luke and I are interested in chip fabrication I'm dropping this email with a link to a story on a SW tool that is designed to help improve designs based on how exactly a foundries process works. Luke, the wording in this article looks very carefully chosen in places. I'm totally in the dark as to why; e.g. "...the platform that analyzes yields enables secure collaboration between the foundry and customer." It's not free software so it might be interesting to try to find something similar offered by the community. Or maybe we'll have to roll our own eventually. https://www.anandtech.com/show/14613/synopsys-to-accelerate-samsungs-7nm-ra… David -----BEGIN PGP SIGNATURE----- iQIzBAEBCAAdFiEEL2N7+xWmVOJDQxWGm3XCrhg2YP8FAl0fkxQACgkQm3XCrhg2 YP9+tw//QiPvROIL3w1015q4PQY/P5yuWW0udlHNG6gO2PZH5uG5mUwaAyOuf3tC zX1MMK+dLdYfsXDDh7su8XLNObuEZC7GCeTq+16qwUdPwbtgy2m4LxbInPOvOE5Q FWnpaluD0RFgBtUDnFEhQcewTsI4xNgbj669NRikrEYysUxxSsIOcRShbFgWIXgi D4swIshef1Nh7Bc0Rl8FAgY0sWGxHSuTPiaFVce/DFSWIJ/b82PCVyJPWNvAjai+ VjX6IwKTADHaeNQzYAL84kuYXUg4cs3xTJ4kLbLfpgBKHrx+EgJcIPcinyc4+d9b 2nd6yvN/+0QQW+OSv1a3Fc+nvZXKAOvBW3VVIsfD50qFE2Lc7OZG5GbUSe2u/wvy +USS5dgzmZkQTGn66Plq51Hwsle2462hH1GIliyR3okZ+G+FWGAlRU4EHZy1GUVN jJgNojjbBX0nEJUzJS66rPQL/WLIlOdzhS4GvGrr4DA6wLm7ZRFbDBEFcFcbHKVw uPaC6HPeXDxFX82HbwrwbOOoVEwCQHUUbQloRC1N8rcDZqeZUfFnfXnazsFhb8gs 10p62JzcEFezCprMfpJj8d3ZsCF9Hezx59BOfExP0ddw8iJJlz1wbkY7vhOjnyb+ xaIDjrA9EE7dmlZ7IpeKoEHoX2K2WOnF3CEJHJVyuy4X0BMiMao= =bCLy -----END PGP SIGNATURE-----

Fwd: [eoma68 update] report back from factory on HDMI
by Luke Kenneth Casson Leighton 04 Jul '19

04 Jul '19

---------- Forwarded message --------- From: Luke Kenneth Casson Leighton <lkcl(a)lkcl.net> Date: Wed, Jul 3, 2019 at 8:16 AM Subject: [eoma68 update] report back from factory on HDMI Mike's staff began the PCB assembly of the run of 100, and had to stop at 36. 20 were ok: 16 of them, the HDMI connector refused to fit. The reason: the CNC machining on the edge of the PCB has not been done accurately enough: it's simply too ragged. The staff did some experimentation, cleaning up some of the edges in the cut-out with an xacto-knife: this did the trick, even though it is shaving something like 0.01mm off the ragged edge of the PCB. The left and right edges do not matter too much, however where the HDMI connector comes in close, it definitely does. Mike is going to talk to the PCB factory to see if there is anything that they can do in future, however with 1,000 PCBs already manufactured, the safest thing to do is probably to *hand-trim* that PCB edge, removing the burrs, on all 1,000 PCBs. Again, to reiterate, because I am still seeing evidence of "complaints" out there, from people who believe this should be easy: these are absolutely ridiculously tiny components and tolerances, and the budget on which it's being done is equally as frugal. 0.05mm on the edge of a PCB. 0.2 mm wide pins, with 0.2mm clearance between them. A "normal" Single-Board Computer product from any other well-funded Corporation would use large (Type A) HDMI, top-mounted, with plenty of tolerances and no need for the PCB edge to be accurately milled. Again, to reiterate: we do not know what will need to be solved next. Therefore, a production date simply cannot be provided, and that really is the end of the matter. Or, the answer is: the production date is "the production time plus the unknown time to solve unknown and unknowable future issues". Mike is sending me the 20 "good" PCBs so that I can test them here, to see if they are okay. The staff will continue with the rest by shaving the burrs on the PCB on every single one of the remaining 80 with an xacto-knife, before putting them through the production line. It is looking like I will need to do the testing of all 100 of this preliminary production run, here, at my home, in Taiwan.

eoma68 a20 card production
by Luke Kenneth Casson Leighton 30 Jun '19

30 Jun '19

(joshua appreciate you're busy with teardown, let's make this one short) Mike got back to me, his engineer completed the review of the BOM, and we managed to work out all of the information that had been lost by Mike's long standing manager quitting with no notice. The BOM still had components in it from the RTC, Ethernet and ONFI NAND, and we had had to change 10uF 0805 to a pair of 0603 4.7uF - all 12 or so of them - when there was that shortage caused by Apple, last year. All of this was *supposed* to be documented as part of the pre-production runs that cost USD 2500 a shot, so that the longer runs are far less risky because a short trial run is supposed to prepare the engineers for the longer one. We cannot keep doing that, it takes 2 to three months each time, so we have to take the risk and go straight to QTY 100. This is just how it is. Patience is required. Success happens by solving each unknown and unknowable issue that comes up. However, it would be appreciated if people would accept that this is not something that cannot be predicted, neither what might happen next nor how long it will take. Continuously asking "when is shipping going to happen" the answer is, always and will always be: until we have actual finished product ready to put into the hands of the shipping agents, we don't know and we can't know. It really is as simple as that. L. -- --- crowd-funded eco-conscious hardware: https://www.crowdsupply.com/eoma68

EOMA68 Computing Devices Update: 2.7.5 Cards Under Way, NLnet, and Intel Compute Card
by Paul Boddie 06 May '19

06 May '19

Hello, Thanks once again for another update on the progress being made with the different boards: https://www.crowdsupply.com/eoma68/micro-desktop/updates/2-7-5-cards-under-… It must be frustrating to encounter production issues (with the Micro Desktop), but I imagine that such things are only avoidable with enough experience of the relevant processes. I suppose that the only way to deal with them is to take the lesson along for next time, pretty much as is noted in the update. Meanwhile, it sounds like the computer cards are waiting for components before being assembled, so we should remain hopeful that their production is more straightforward. It will be interesting to read the next update, certainly. Paul
