I am still collecting information, before I can make a precise estimate, but
please expect >> 10k €.
One part is that this needs a new stencil, production preparation (there is one
person sitting
one day to fill the component feeders) and the production run itself. Which
would be 1 day
renting operator persons plus machine operation time. And someone has to test
and potentially
fix all the devices. This will be somewhere between 5k € and 10k €.
Another major factor in this calculation is that due to the delay and our
problems there is now
the Librem 5 ready for preorder at 599 USD.
This makes it unlikely that there are still enough Openmoko friends who prefer
to buy a GTA04A5
board at the planned price of 444 € or a complete Letux 2804 at 584 € plus VAT.
This price was
calculated to cover all cost under the assumption that everything goes well
(with some reserve
for problems - but this has already been used more than completely).
So a more realistic price would be 244 € for a GTA04A5 board and 384 € for a
complete
Letux 2804. The production is ca. 60-70 boards limited by the remaining
components. So this
means another ca. 13k€ is missing because of this effect.
If we find a gratuitous donator covering the additional cost (and risk that it
will fail again),
we could give it a try to build the final batch of devices. We could even
invite the donator
to participate and watch the production run.
Thus, a rough estimate is that in total it is ca. 1% of what Librem 5 has
collected... Or
one 10-pack of Librem 5 + 30 inch Monitors.
So if someone wants to donate or knows someone :)
