I covered another video from Justin Atkin about his journey to make spider silk with genetically-modified yeast, which is the second time I've covered this scientist tackling this project. Still, it marks the completion since he successfully produced yeast that will excrete silk. The next steps will be making things out of the raw silk.
I printed the parts I started last week. The mirror spacers worked right away, but the shuttle needed some work. The first version required some changes, and I promptly made a new one. My revision was shorter, had a hidden magnet holder, and the viewport's center was directly between the magnets.
Puck revision
To create sturdy and inexpensive servo arms, I designed some rod-ends to mate with bearings or fit directly onto a servo. To make them strong and light, I will place a rod into the socket, and with the cleats on either side, I can reduce flexing and twisting.
Models for rod ends
I sketched up and cut a new board. This one has sockets for a couple of servo motors. I won't be using this for the final version, so I grabbed some scrap plastic from the hackspace. All I want to do with this is test how to use the servos, and the rod ends.
Upgrade to servo sockets
I connected an Arduino to a couple of potentiometers and a couple of servo motors. The microcontroller holds to a prototyping board with friction instead of soldering, keeping it steady. On the backside, I connected my test wires between the pins and devices and used the prototyping board to split power and ground between everything.
Motors mounted or servos secured
Before testing, I assembled the arms from bamboo skewers and the 3D printed rod ends. I didn't add strings, but there were a few areas where I need to improve my designs because the parts were failing. Even with damaged parts, and a rudimentary Arduino program, I got the puck to move.
