yyeahh... there's a whole stack of that >> the boards i want to do another run in the next few weeks, wookey, so >> if you'd like to buy some you'd be most welcome. i don't want to get >> too many done in case they need modifications. they're only >> single-sided 2-layer 1.5mm thick so are "bog standard" i.e. dirt >> cheap. i think this time i'll get them made up rather than do the >> component assembly myself. > > I am interested, but I was a little put off by the prices you listed > last time at $120-150 per board and 3 boards. a qty 5 figure is $1700 for the CPU Cards (including components and assembly). a qty 5 figure for these 2-layer single-sided PCBs is going to be waaay less than that. i'd put a guess of around $60 for PCB1, $50 for PCB2 and $50 for PCB3. massive difference - just because of using simple 2-layer and 1.5mm. the $120-150 was because i was using eurocircuits. i think it was around that much for PCB1 (qty 2). i'll get everything done in china this time. > I don't call that 'dirt > cheap'. That's $430 + screen+keyboard+panel+printing, which is a > little more than I want to pay for just 'mucking about'. i added up a rough MOQ 200-1k figure today and it came out to a BOM of around $190, excluding assembly costs. which honestly isn't that big a difference from the qty5 figure. > I could > afford it but a) I'm tight and b) I don't like buying electronics > unless I'm fairly sure I'm going to get decent use out of it (all that > eco-thinking). good for you! so the question becomes: is it worthwhile for you to spend the time as an early adopter, to help "prove the concept" - i'm pretty sure it'd be possible to find a home for the end result (i have to give one to dr stallman for example). > And ultimately a 2G RAM laptop is 'toy' these days, > because 'browsers'. *sigh* tell me about it... bear in mind this is only a 1366x768 LCD. > So I was waiting to see if the upgradability > aspect looked likely to actually solve this issue, and I have a pile > of other half-started projects so don't _actually_ need any more :-) > haha > So, er. 'maybe' :-) How much and when? let me work it out more accurately, likely timeframe 2-3 months. i'd like it to be before 2 months as i'm leaving den haag end of march. >> so if someone can confirm whether this is true or not, i'll >> re-prioritise the allwinner A64 board back to the top of the TODO >> list. > > Karsten Merker explained this at some length after my talk (he has a > pine).
