OK, thanks. In that case, what is the path to a working pre-production prototype?
in the updates, nick. another one due out shortly.
OK, I see https://www.crowdsupply.com/eoma68/micro-desktop/updates/progress-physics-ta... It mentions micro-HDMI replacement, casework, and the pros and cons of buying equipment for sme DIY prototyping.
another one's out in a day or so, that's the one i meant
http://rhombus-tech.net/allwinner_a10/news/ shows PCBs from October.
yeah i keep meaning to update these
Somewhere in http://lists.phcomp.co.uk/pipermail/arm-netbook/2017-March/ is something about memory and resistance, but I can’t find it in my 5 minute search.
sorry. lots going on. basically i had to find the new HDMI connector, and test it, but at the same time i also had to find a new NAND IC. it's made even more complicated by the fact that the first new HDMI connector turned out not to be suitable and we had to find *another* one. each time that happens it's another $1.5 to $1.8k gone and about another 4-6 weeks gone doing the board design, board gerbers, waiting for 2 weeks for the PCB to be made, waiting another 1-2 weeks for the PCB to be assembled, waiting another week for it to be shipped to me, waiting another 3-15 days (or longer) for me to find the time (or equipment) needed to test it....
if there was enough funding i would simply have given these tasks to a contractor, paid them $10k-$20k and told them to get on with it. however it's simply not that simple or straightforward, and they would likely run into *exactly* the same sourcing issues... just with a cost overhead.
then there is the casework. i have to get a laser cutter and work out how to set up a jig.
all of this is - i believe - in the last update and the one coming out.
I get the impression EOMA68 is a jigsaw with many pieces. I hope it’s all coming together.
a huge one that starts off with a small centre then grows in layers, multi-dimensionally... yes :)
