been done....

Connection machine CM5 :

and it will be hard to beat.

I would love to see Dave do a teardown of these beasty (and also on of the Cray.. :D)
When you make hardware without taking into account the needs of the eventual software developers, you end up with bloated hardware full of pointless excess. From the outset one must consider design from both a hardware and software perspective.

I think that since we all agreed on using batteriser on this appliance, we have to customize a pick and place machine to automatically replace discharged batteries (we can hotswap them, because of course we're doing the medical stuff things - 2 batteries in parallel to make hot-swapping easy). That would gild the lily and add few pennies to the total cost.

I'd waste it all on R&D because of my requirements to be World Class in green energy. We need to source the best LED and a very precise resistor and low ESR capacitor.

In fact, I think we would hire someone to make an ASIC for the LED blink RC timing, then have them make the LED with the tiny ASIC already on them. Given they can meet the specs for the worlds best resistor and capacitor (of course they will! their contract says so after all).

Now it's time for me to align with the marketing department, and I'm sure they will have meaningful input for the progress of our product....  :blah:

RC? You HAVE to use a GPS disciplined rubidium clock, if you don't, then what's the point?

Timing signal for the LED blinky will come from a geo-synchronous satellite sending on/off commands.

Cool! Then a change in interval can be used to deduce at which angle the satellite is as well (when moving further away - or close to it on earth). Bonus feature :)

It needs a satellite tracking system to reduce the effects of doppler shift when the device itself is moved around in a vehicle.

Virtex 7 FPGA
Rubidium or Cesium clock source
Red LED encased in laboratory grade Ruby.

Or theres this:
