For this month I was working on finalizing all the materials that I needed to purchase. I decided on the power supply and the microcontroller that I would be using. I also decided on the tubing I will be using to transport the balls from the bucket to the shooter. This was challenging as I was unable to find a relativley cheap but highly flexible tube that was just large enough to fit a ping pong ball through. I will be using a wider diameter (~2 inches) and snipping down the length of the tube then zip tying it to be just the right size. I also ordered the chains for the mechanism and kept editing the CAD file to make some further adjustments for rigidity.
