23-24 Week of 12/04 – 12/08

Hard to believe we are already in December, but the light snow fall we had last week reminds us that winter is here.

This week Junior Will Tseng worked on a CAD project for some coat hooks. He writes on his blog:

This week was a lot more eventful than last week. This week I decided to design new hanger hooks, start the dual enrollment process, and did a favor for Tanzerul. I decided to start making the hanger hooks so I could have a place to hang my hoodie without it taking up space in my small locker. I spoke with Mr. L about it, and I quickly got to work. By the end of last Friday I was done with the model, and on Monday I came into school late just so I could print it. I liked it, but Mr. L said it contained too much hardware. The hook was created with a square mounting piece, two bridges connecting it to the hook on each side, and used nuts and bolts to hold it all together.

It was very sturdy. However, Mr. L said it was using up too much hardware. He is probably right. The new design is it’s own individual component, and has a hole in the hook so a screwdriver or drill can reach in and screw in the screws. The new design is the featured image. The last thing I want to mention is the small nuke I am building for Tanzy. He asked me politely to build a nuke for him, but I found out he plans to resell it to another friend of mine and earn money as a middle man. But hey, he asked me politely. Next week I am going to learn how to use a Hammer Drill.

Senior Shubh Patel is perfecting the 2D plotter. He is upgrading the electronics and discusses it on his website:

This week I mostly worked on designing the pcb which will have ability to control the everything in PenPlotter. This new design will mount on top of the Raspberry Pi. The design is not finish yet, I still have to do Voltage level shifter converter between Raspberry Pi and Metro Mini because that both use different voltage to function.

This is the Voltage level shifter circuit that I will be using in my pcb. This circuit takes 5v from metro mini and 3.3v from Raspberry pi and change voltage accordingly to which device data going to.

The Sophomore class spent the week designing circuit boards on the computer for their LED Lightbox project. The process of designing circuit boards on the computer is tedious, but they are doing a great job! Can’t wait to see the finished products.
