Saturday meeting

We got together on the 13th for a bit of chat and fiddling with our projects.

The yet-unnamed Water Tank Bot  (WTB?) took a big step forward with test mounting the body.   It has 3D printed custom brackets mounting the tank bottom to the supporting seat frame atop the wheelchair chassis.

The tank doors came out really nice using a very simple but smart build sequence.  First, the hinge line was cut in the tank.   Next, the piano hinges were mounted via pop rivets, and then the final cuts in the tank were made on the top, bottom and split center of the doors.   The doors swing easily and have perfect alignment.

Behind WTB? is the CopperBot, which recently had some detail work for better antenna mounts, less camera vibration, and securely mounting the RCA 833A tube.

The First Person View base station was rigged up on the bench for a demo and to measure power requirements.   With the receiver and 7" display, it's pulling 0.416 amps off a 12v SLA.   It will need a bit more power with a small audio amp and speaker.
