Day 3347

 I woke up a little after 7.  After playing games I got up for pet stuff and breakfast.  I'd planned on going shooting, but the day was cool and cloudy.  I should have gone as later it cleared up and was warm.  I did a little surfing instead and then started working on the contraption.

Most of the remaining steps weren't complicated, but some of them were mechanically difficult.  When I got to step 108 (of 114) things went south.  The step involved wiring up the various power inputs, LEDs, switch, and motor.  It was all supposed to be connected using a terminal block.  Unfortunately the terminal block was cheap Chinese shit.  Some of the terminals wouldn't hold wires.  I ended up soldering a lot of the wires together.

Once that was done it was time to do a final functional check using the motor.  It failed miserably.  I went through everything and corrected a couple of interferences that were holding things up.  It still didn't work.  Eventually I figured out that the drive gear was slipping on the motor shaft.

The drive gear has grub screw holes, but the design doesn't use them.  Instead it uses a screw that screws into the end of the motor shaft.  The result just doesn't work. I had to disassemble part of the device to tighten the screw.  I put everything together and it worked for a short time before the screw came loose again.  I'm going to have to take more of the device apart and totally redo the connection between the motor shaft and the drive gear.

I'd spent most of the day on the stupid thing, so I decided to quit for the day.  I did a lot of surfing instead. 

Ellen fixed coconut shrimp for dinner.  It was from Costco.  It was as good as any I've had at a restaurant.  It probably was the same as what the restaurant uses

After dinner was videos.  I tried to watch a couple of movies, but I quit both of them because they were boring.
