What's (been) happening?

It has been a little while and as you can imagine things have been busy and very hectic. Here is an update on the various items:
  1. Last Monday, the last revision of the PCB came back. Although I placed it as a rush order, it was late; it was supposed to have arrived the Thursday before. In the meantime I have built a new GPS module with it and tested its performance, which is up to spec now. This new module is shown in the photo (inside of the new housing prototype).
  2. The biggest milestone that got done this week is the new two-piece housing design. This has pretty much kept me busy full-time since last week:
    • New 3D CAD files (no logos) were completed and a new FDM prototype was made to verify that everything fits inside of it. I painted the prototype black, put the latest board inside and hooked the USB cable up. The result can be seen in the photo.
    • The next thing in line was sending out the new 3D housing designs to get real prototype housings CNC machined out of solid ABS plastic (no FDM). These are needed to do proper antenna tuning of the board and the housing for optimum GPS performance. These housings are expected back upcoming week.
    • Next I had to finalize the drawings for production and place the logos on them. This did not go without hick-ups and quite some time was waisted trying to get the 3D software to accept the graphics files. But eventually I managed to get everything imported.
    • I am currently detailing the lens a little more to make sure that the LED light comes out properly and has a wide viewing angle. The final CAD files are due first thing Monday morning.
    • A purchase order (PO) was placed for the injection mold making and a delivery of 1000 housings. The housings are to be completed by September 9, 2008.
  3. I also received new GPS modules with updated firmware for this new PCB design. I had problems uploading A-GPS data to them. I thought it was a firmware issue, but after talking to the GPS vendor it turns out that the A-GPS upload tool that they provided had some problems, so they provided me with an updated version which performs better but still seems a little buggy. After we get a final OK from the vendor on the module configuration and firmware, we can place a PO as well (I hope this can happen this week).
  4. Regarding contract manufacturers, I have converged on a candidate for PCB manufacturing and assembly with competitive pricing. I might have to make a few minor adjustments to the bill of materials, but after that we can get the ball running.
It looks like the Orange Gadgets website has been running pretty smoothly. As of now, 177 people have signed up so far for a total of 208 modules. Feel free to do some additional advertising among your family and friends as well as online.
