Looks very good!<br>
<br>
If i'm not mistaken, Tesla used a similar extruded aluminium box
for some electronics module next to the VMS.<br>

<div>I thought you might be interested in seeing some early
pictures of the prototypes for the vs basic hardware we've
been working on with the China team.</div>
<div><br>
</div>
<div>Some notes:</div>
<div><br>
</div>
<div>
<ul class="MailOutline">
<li>The design uses a metal rectangular "tube" style case,
customised for us and cut to the width of our board. The
case ends up about 7cm x 6cm. Labelled end-plates will
go on, with cut-outs for the various connectors. The
original design called for this to be black in colour,
and we're still deciding on that (as the silver doesn't
look bad and will be mostly covered with a black sticker
anyway). Opening it involves removing the 4 screws on
one side and sliding it out.<br>
<br>
</li>
<li>On one side we have the CAN (and power) DB9, GSM and
GPS antennas. On the other side we have the DIAG DB9 and
expansion bus connectors.<br>
<br>
</li>
<li>Holes for the LEDs are on the bottom of the case, and
the LEDs themselves are on the bottom of the board, so
that they are as close to the holes as possible.<br>
<br>
</li>
<li>There are zero internal cables, and only one circuit
board containing the PIC controller and SIM908 modem -
connection to the car is via the main CAN DB9, using
custom cables. We have tried to follow ODBII standard
pinouts for that connector.<br>
<br>
</li>
<li>For Tesla Roadster, we can use a custom 4 wire
connector (Tesla DIAG port connector on one end, DB9
female on the other). For ODBII cars, a similar
arrangement can be made.<br>
<br>
</li>
<li>The SIM908 modem chip supports GPS for those cars that
don't have it.</li>
</ul>
</div>
<div><br>
</div>
<div>Still early days, but the design looks workable and
should be much easier to assemble and QC than the v1
modules. Rock solid and (probably) bullet proof. It should
also have good support for cars other than the Tesla
Roadster.</div>
<div><br>
</div>
<div>Regards, Mark.</div>

</div>
<div>P.S. I'm also working on a more advanced hardware
solution, as a personal project, that may end up being
offered. Just experimenting at the moment. William is also
working on some solutions for this based on *bone hardware
and shields. These are much longer term, and we'll send out
more details when we have some progress.</div>
