Good thought, , but the cs8900 would probably overheat if there is not enough "open space" around it. It generates a lot of heat.
That is what I am looking into for the second run actually. I would have to totally redesign the board which I am willing to do. All the components would have to be surface mount devices because anything through-hole would have to be hand soldered and that would make such a small run too expensive. Also, I can probably make a single board device fit into a standard cart shell except for the RJ45 port, which would also make assembly much easier. I have to make some calls and try to get an estimate for such a board assembly before I do any engineering. I know it's possible, but I am concerned about the cost. I want to keep the cost of the cart under $50.00 if at all possible.
You are very welcome. Thanks for posting the pics. It's really cool to see them out in the world and being used!
Are there any more for sale?
