I'm making the adjustments to allow all three types of chip to run on the same board... needs a few more controllable regulators, some different coils, and a new footprint for the A1 - probably the hardest thing to do in the list. Spent today cleaning up the schematic, making the bill of materials consistent, and ordering the remaining parts that I had overlooked or added since three weeks ago.
Planning on Footprint next, then just wiggling it into the layout, and adjusting the high-current loops for low inductance. I will finish the layout of the LEDs, MCU, CPLD, and JTAG. If I get it done before the "shop" closing time, I'll take it down to the "shop" for a milled prototype, and use that to prove out the MCU, hotplug, and power controls before I send it off to the prototype fabricator, soon hopefully.
At that point, I'll spend that time getting the bringup tests written, and testing the new OS on the emulator. When the boards get back from the fab, I'll give them a once-over, and take a few to the shop to assemble (only partially, since they can't place the real fine- line stuff we're using with their old gear). Meanwhile, I'll have the parts kit completed (last few will arrive soon, suppliers are telling me), and I'll ship them all off to the assembler for a fast build of 4 or 5 demo proto boards.

Me too. I am not just a WPC member but I am a real fan of the project designers hell any engineers that do this sort of work really so many great ones in our community. The past few months of CAD design hell have really been painful to watch the EE go through and I am sure there are still some gremlins in the mix still to come but it be nice to have the next couple of meetings be all good news.
