I have good news from Spain: the atben/atusb PCBs have been delivered.
The next step will be to take them to the SMT fab and get them
populated with components.

I hope we'll get some pictures of the PCBs later.

Now, there is one item that's still undecided, and that's the case.

One option would be to just ship the naked boards and leave wrapping
them nicely completely to everyone's imagination.


Another option would be to cover them with some sealant that will
protect them against anything but extremely rough handling. The
following materials have been suggested:

- Silicone (caulk)

- sugru (a fortified silicon), http://sugru.com

- resin (polyester, epoxy, etc.)

Silicone and particularly sugru is easy to handle, which would make
it possible to ship the devices with just a sachet of the sealant,
for application by the user. Sugru and silicone are available in
reasonably small portions.

Silicone and probably also sugru can be removed without residues, so
a damaged cover could be replaced, the board can be reworked (e.g.,
to add an antenna socket), etc.

A resin would offer better mechanical resistance but would be
difficult to remove.


Another possibility would be to make a real plastic case. Cristian
Paul did some early experiments with 3D printing. Joachim examined
a USB stick to see if an existing case could be reused. Victor is
thinking about designing a new case for injection molding.

What all three approaches have in common is that they would add
significant production overhead and it would take some more time
to make/find and debug those cases.

A proper plastic case would offer the best mechanical protection
and the most professional appearance. One could also select/design
it such that it can be disassembled.


A two-phase approach would also be possible: bundle boards with
silicone or sugru and ship them soon, see how things go, and then
consider developing a proper case.

Opinions ?
