Schematic and PCB layout CAD files
by Arun Isaac 01 Feb '22

01 Feb '22

Hi, Are the schematic and PCB layout CAD files for the EOMA68 computer card and the various housings available for download? I'm wondering if I can fabricate some of the housings on my own using a CNC mill. Hence, my interest in them. Sorry I had to ask. I searched very hard through the crowdsupply page and the rhombus-tech site, but couldn't find them. Thanks, Arun.

Deja vu

Hi luke, Linus (not Torvalds), mentions every project but yours when discussing this "lap dock", a laptop without internals to which you dock a device, such as a phone, or raspberry PI. It's known as the Nextdock2. https://www.youtube.com/watch?v=SIJAEcOL6sI It never ceases to amaze me how many copies of your project I come upon online. I almost think it is a great idea. :D Sincerely, David

How about an opensource nuclear reactor?

Dear luke, Such a project might not be ligament (I'm not a physicist), but people seem to be taking it seriously. As of this writing 2 of the files are still missing "PRIMARY LOOP" and "STEAM TURBINE". https://www.open-100.com/ David

$ available: python programmers needed on LibreSOC
by Luke Kenneth Casson Leighton 05 Mar '20

hi folks i need some help with the chip layout, it would particularly well suit a student or someone needing part time income. the actual layout is quite straightfoward to do, if you have ever done PCB Layout it is pretty much exactly that... except it is done as a *python* program. you call a *function* to place an adder block, rather than use a GUI, and then view the results *in* a GUI in order to review them. here is one of the experiments, which will need significant tidying up: https://git.libre-riscv.org/?p=soclayout.git;a=blob;f=experiments5/doAlu16.… it is however "functional" and demonstrates the principle of routing smaller blocks then placing them and routing the larger block. this hierarchy needs to be about 2 maybe 3 levels deep, around 100 "blocks" which will need careful discussion. no *actual* "hardware" experience is required, it is simply "call this function to put stuff here, call the routing function, save the file, move on to the next block". anyone interested or know anyone who might be, do get in touch or pass this on to them. thx! l. -- --- crowd-funded eco-conscious hardware: https://www.crowdsupply.com/eoma68

Could you explain the details of the 3D mesa driver you need?
by David Niklas 05 Mar '20

05 Mar '20

Dear luke, I've been very curious about this, but I've waited until you were stuck in some place before asking so as not to busy you. I'm not arrogant enough to say I'll create the 3D mesa driver or even go beyond theorizing, but I'm very eager to learn. 1. How do we know when it works? Is there HW or an emulator system we can use? 2. How do we know it's fast enough? What do we benchmark it with? 3. What exact APIs do you want implemented? 4. Do you want it in assembly with C and/or C++ bindings or in one or both of C/C++? 5. Are there any special assembly instructions that this will need? If there's anything else you think would be useful, do tell. Thanks, David

haven't seen updates for a while and I wondered if its still being released, the eoma68 laptop. :/ I would appreciate some updates you know. If its okay. Sorry, if this sounds demanding, I am sure your running into your share of barriers.
