Greetings!
Sorry for the delay in writing. It's been busy with "visitors", lately. It was good seeing all of you -- looking forward to April!
I made the Doppler additions to the demo you saw. You should be able to play with it on your existing hardware. There's a ReadMe that explains the controls.
I started porting the OS to a small ARM development board. Goal is to make sure there are no big "gotcha's" before moving the designs to foil. Having to redo *one* would be annoying; redoing ALL of them would just be depressing! : )
Let me know if Vegas or SoCal in April. I'd also be happy to let it slip to May (all the recent visitors have me WAY behind! Still a few more "obligations" to address before I can get back to life as usual...). Much later than May would probably invalidate Vegas as an option (?)
Good seeing you all!

P.S. Managed to harvest the Valencias the other day. Some 160 pounds on that one tree! Already juiced about 7 gallons and still have several bags of fruit left. But, *nowhere* near as sweet as the juice from the Navels that you had while here.
