- i'm thinking of putting the "pass through" card on the campaign, approximate pledge amount $40 (because in low-volume expected it'll be about a $20 BOM), that would turn the laptop housing into a battery-operated screen, keyboard and trackpad for any smartphone, USB-HDMI-dongle-PC, laptop or desktop PC. thoughts appreciated on that one.
Go for it !
I'm not aware of the cost you would have to bring it in before the campaign deadline (is it finished, tested, ready?), but if you can do it, don't doubt.
it's been planned for a long time, i can estimate the BOM (not a lot
- about $6 of components) it's the PCB manufacturing that will be a
bit more than usual if the quantities are small, even if it's a single-sided 2-layer PCB
No idea about those calculations. You said around $40 for the backer to get one, that sounds about right. Psicologically it's still more than half the price of a CPU card, and it doesn't carry SOC, RAM or storage. That may be countered with just publishing the BOMs of both the passthrough card and CPU card (if they aren't already). But even without that, $40 it's not so off the mark.
If it can be 30$ or 32$ you may sell more.
... yeahhh will think about it.
If it comes to $50 it starts to look too close to $65 (CPU card) or to $55 (desktop, but I'm not sure this is a valid comparison) and people might think twice. I can't calculate the point where the sales volume outweights the lower profit per unit. No idea.
you could put the pass-through card into the micro-desktop as well, that's the hilarious bit.
I'd even say ask for more PCBs than pledges to anticipate future sells, but it's not my own money I'm playing with so I'll refrain. I'm sligthly surprised by the small amount of laptop orders so far, and I haven't thought much, but I don't see the passthrough card+ desktop as even remotely as interesting as pasthrough card + laptop.
yeah exactly - look at the http://nexdock.com/cool-uses/ it becomes clear, oh, also, it looks like someone there found a WIFI HDMI adapter of some kind :)
Other components are unique (like female connectors instead of male or something) or can they be grouped with components for other rewards and so enjoy the price of larger orders ? I don't have an idea of MOQs, price/quantity intervals or anything.
nono, i can use the same micro-hdmi and micro-usb-otg as on the EOMA68-A20. getting hold of the cables for tablets and smartphones, have to look those up, can do it in another update, you need a micro-hdmi-to-micro-hdmi and micro-otg-to-micro-otg which i've never heard of so might have to be done as a multi-set of converters... ehh will work it out
Another factor is time. If it is ready to offer before the deadline it makes sense. If prototypes, testing and so on takes longer, then maybe it'll have to wait to future campaigns...
it's simple enough to do (about 20 components) but i feel comfortable explaining to people what's going on.
then again you've probably seen the USB-HDMI dongle PC connected to motorola atrix lapdock "version 1" instructables.... you can't use the version 2 as they DRM-locked it.
I haven't seen that. I don't really imagine what it is right now. Worth looking it up ? I lose interest when reading DRM...
the nexdock is more interesting
Whatever it is it can't possibly hold the promise to host a EOMA68 cpu card with someone's favorite SOC in the future, can it?

chris (havel) would you like to have a go at making something using that program you use? let's put it on the community_ideas page
