Well worth a visit. Norm Barrigas is the guy we usually work with. They are not just CAD guys. They know the manufacturing process so what you get from them can be built. That "RioRey" chassis on their web site is just one of the things they have done for us.

I really do value this point...I am the digital/sw/analog geek, my cohort is the analog/RF person....I will make sure he sees this...and just by happenstance, how did you know that we use the MPS430? ;) sweet lil device. Yea, I've been a little in 'discovery' mode and it does pay to design with knowledge of the issues before hand. Just like doing taxes and penalties..."I didn't know is not an excuse"....
Product brochures are a ways away....We have convinced ourselves that the unit meets functional, and some quality attribute requirements, so many of those can be listed, but want packaging close to actual to slap on page..
I actually got to 'tack' onto the MSP430 a 'distance' measuring sensor. Measured from 6 to 27 inches, using magnetic field strength as a function of distance. The Tx and Rx took only a total of 5mA. At a distance of 8 inches the 'measured' noise was 1 mil rms!
The whole system had multiple sensors of various types, ran for 4 days on a cellphone battery, could talk with Bluetooth, or zigbee, or Wifi and had cellphone link,'just in case'
That's where I learned that one of the modules had a mistake in its certification. The FCC forgot to add the exclusion that if the antenna were near another antenna all bets are off. Sadly, no other module had that error so it was only THAT module that had its certificate valid around the other antennas. So had to go back to test the WHOLE thing in the most complicated set up I've ever seen. It was a test lab in San Diego area, but can't find their name now, very knowledgeable AND recommended the SARS people.
The system had to be split onto two PCB's [which I hate, beacuse it's difficult to make RFI/EMI quiet when you split a board] and the battery was connected badly, long ways out. The distance sensors took four 1 meter cables that could be located anywhere. AND whole thing in a plastic box. I got my two cents in right from the start and defined interface protocols, and a bit of the box diagram pieces. By doing judicious design and adding around $0.30 worth of components I got the compliance I mentioned. Two weeks later when back at the test lab some employee [who didn't know who I was] was asking me if I'd heard about the guy who brought in a unit so quiet they couldn't tell it was ON. And that's my claim to fame, ...for the day anyway.

ds), and tested my creation, and now I'd like to package and offer it for s ale.
llowing in order to have a packaged product to ship (assuming I have the bo ards assembled and tested):
ing, assembly of plastic and metal parts into enclosure,etc.
converter, cables, etc.
to bulk ship the order to me (for sales).
box with power supply etc. is sometimes more work than getting the electro nics working. I usually pick a box before I lay out the pcb. Connectors, switches, displays.. getting all the mechanicals in place, that's the hard part.

So very true. So far, we have had to spend the maximum time correctly managing the mechanical parts of the product than the electronics. Recently we built a precision power supply with a number of adjustment pots and 3 digital displays for a client. It took 2 days to carefully adjust /place the wires from the pots to the PCB such that they do not impede cooling air flow inside the box, and also not touch any of the hot heat sinks(8 of them) inside or the fat transformer inside - otherwise the wiring insulation might get damaged. The enclosure is 12" x 12" x 3".
