2018-10-05 (F) Weekly Summary

Robots can get damaged, and that may make them stop working. Researchers made a substance which will reroute signals in the case of damage. It seemed like a neat idea even if it is beyond the manufacturing ability of the average hacker.

Programming for the lights was done with Adafruit's DotStar library. This was a remarkably easy library to use since it was created to act like the NeoPixel library which I was already familiar with.

Soldering on one board was done. This was done with proper solder paste since there were fine solder joints, but it still resulted in a few bridges, which can be seen in the picture below. A hot plate was used to heat everything from the bottom. During the design phase, all the components were populated on one side of the board so that this was possible.

Soldered microcontroller

A new revision to the board was made when it was clear that I would not be able to program a bootloader unless certain pins were broken out. One solution was to create a new board. It would have been possible to program the chip before installation, but it would have added more steps for anyone recreating the project.

Next revision of schematic

The fan blades had been neglected for a long time. A few abstract patterns were drawn with a brush pen on graph paper. These designs were converted to vectors and cut from wood on the laser cutter, but it turned the wood to filigreed cinders.

Abstract designs

Blank wood panels were cut for the fan panels. They may have been too heavy for a finished product but the point of the first ones was to test the folding design. They were designed with curved slots and small holes for rivets. The point was to install protruding rivets which would ride in the slots and provide a limited range of movement.

Wooden panels with holes and slots

Sadly, this project lost momentum and stalled here. No further development was done but it could be resumed in the future.

The rest of the summary posts have been arranged by date.
