Day 3289

 I woke up at 7:30, played games, and then got up for pet stuff and breakfast.  After breakfast I surfed for a while and then got out the RC stuff.

I'd been putting off doing the final work on the Chevy.  Theoretically all I had to do was turn it on and program it.  I just had a bad feeling about it.  The bad feeling was justified.

I got the receiver and transmitter bound.  The throttle and shift worked fine.  The steering didn't.  All the steering servo did was quiver.  The rest of the day was debug hell while I tried to determine what was wrong:

1. I re-soldered the wiring of the connector I'd put on the servo.  No change.

2. I explored it being a receiver problem.  I tried 5 different receivers.  They all did the same thing, even with other servos.

3. That made me look at a transmitter problem.  Using another model made the stuttering go away.  After much experimentation, and the manual, I discovered a weird parameter that was set wrong for the model I was using.  After that the other servos worked, but the one in the truck still stuttered.

4.  I removed the servo from the truck and tested it on the bench.  It worked fine.  I re-positioned the servo and reassembled everything.  The servo would barely move.

5.  I decided it was time for a new servo.  None of the ones I have will work with the very non-standard servo saver.  I went looking for an OEM replacement on the we.  No luck.

6. I finally decided to use a servo I have, but there won't be a servo saver and I'll have to fabricate a servo arm.

7. I did manage to get the ESC programmed.

All if this took hours and a lot of frustration.  Part way through I played games while a test battery charged.  I also took Ellen to the doctor.  She has the flu.  The doctor gave her a prescription for a $180 pill.  Insurance didn't cover it.

In the evening I managed to get in a little video/nap session.  I also watched the movie I was watching last night until it got boring.  I may go back to it.

One good thing was the plastic sheet to repair the plant enclosure finally showed up.  I'll probably work on that tomorrow.  I'm sick of that truck.
