Its up date time, everything looks good. Testing the motor for long term high speed. The original coupler failed at 8700 miles. The reason it failed was the mount was off center, causing strain on the coupler. And the motor was 90 degrees. Now the coupler is perfect and the motor is only 58 degrees. The electronics are coming along, we should be testing the prototype in a couple of days.
I just want to thank the whole board for the support. We are working hard on this to make it happen. I need it to happen, I am driving my wife nuts!
Thanks again everyone!

OK Guys just got off the Phone with Tim AKA zipster and i will have a Prototype to take on the 2012 Hot Rod Power Tour for all you guys to look at. I will all so have one in my car for testing to give Tim and them real world feed back on a Long 1300 mile trip. I am so happy to be testing this for Tim and i will do my best on the Hot Rod Power Tour to give you guys all the info i can on this GREAT new item to the LS world.
Congrats Tim for the GREAT work you are doing to help all use LS guys out.

If THIS kit can be made to work, you will have a speed sensor signal.
cadence, I need more info on your car. What computer, differential, body of vehicle(brakes)

Small milestone, The test Mustang speedo has been running for 4 days at 140 mph. The motor temp is at 56 degrees, within 1 degree of ambient temp in the garage. The motor is just whizzing along. So far there are 13,593 miles on the test unit. No failures, no problems. I rolled back this speedo to 0 miles to start testing to keep accurate track of miles.
This speedo is missing the needle. I had to mark the small drum on the back to see how fast its going.

Just a status update on the logical/electronic portion of this project - the base code for the embedded program compiles and loads fine. I am still tweaking the motor power supply design for the final (need to make sure it can take supply tension loaded up to 35v, isolate errant currents and filter high frequency noise, jitter, and compensate undervolt conditions down to 9v), but my base PSU and amplifier designs are currently running on a breadboard on my bench and driving the motor well. Tim is taking care of the mechanical aspects of the design like a boss, so we're looking good. I still need to write the calibration and test signal generator modules. Should get to that by tomorrow night.
