23-24 Week of 3/25 – 3/29

This week Junior Milo Austin had several projects in process. He discusses each on his website saying:

Instead of working on my guitar parts this week I worked on the fish feeder. Before 3D printing all the parts that I would need my teacher gave me the idea of making it out of metal so I that is what I shifted my focus to. I was unfortunately set back by many set backs with the 3D printers this week but I was able to laser cut the new style of disk that will be ready by the sensor inside the fish feeder. The new sensor is made with screw holes so it can be attached to the augur and not more securely.

Additionally to test the size that I will need for the connector I printed out a test version, this is also to help me measure the that the disk needs to be from the motor so I will know where to make the lip to screw it in.

Senior Shubh Patel continued his work on the 2D plotter. He writes on his website:

This week I worked on getting single font writing to work. This picture above first read the .txt file and changes “tabs” into 4 spaces because the library I’m using doesn’t work well with tabs inside files, then I converts txt to Gcode using hf2gcode library. After that I read the Gcode file and change G1 Z to M3 S to make it compatible with my pen plotter. This “M3 S” moves the pen up and down. I also remove G0 Z line because it’s not needed for pen-plotter. I also added button on my flask server to Manually control paper roller if needed and added emergency button to immediately stop the pen-plotter if any thing goes wrong.

It was a busy week for the Sophomores, as many spent long spans of time standing in front of our 3D printers ensuring their prints were coming out correctly. We also had several Sumobots testing their motors in the ring – so great to see some of them actually coming to life!
