22-23 Week of 2/27 – 3/3

Hard to believe that last week brought us into March already. As we welcomed our students back into the shop after the February break, students are continuing to make progress on a wide variety of projects. In addition, we are also competing again in the Can Drive, and are currently in 2nd place. We need a big haul of non-perishable items this week to try and take first place!

This week senior Josh Pahang continued to create the circuitry for his complicated chess board. He writes on his blog;

Hello everyone! This week I managed to fix the PCB.

The problem was with the transistor. I accidently switched the transistor pins around on Eagle and got confused, so I improperly wired the transistor, causing the weird double lights.

I swapped the pins around and rewired and cut new boards. After a slight change to my code, the board correctly reads the pins.

All I need to do now is figure out how this will go on my board and how I will be able to properly space my PCBs as the wires take too much space.

I was honestly thinking of short jumper wires a substitute but I don’t know if that will be good in the long run, I will have to check with Mr. C.

Now that everything works, all I need to do now is create 14 more of these PCBs and make more chess pieces. There could be other additions I could implement into my chess board design, but for now I am content with what I have right now.

Below is a short video of his project.

Junior Cormac Lynch has nearly finished his Light Box project. He wrote in his blog this week:

This week I started getting back to work on my Lightbox, but I was having trouble keeping power plugged in. To fix this I made longer wires so they wouldn’t get pulled out. After this I realized that one of the buttons wasn’t working. This made me take the hot glue off the bottom of my PCB in order to resolder the button. Unfortunately, this messed up some of the other soldering. I needed to reprint and resolder my PCB afterward. With this new PCB, I will finally be able to complete my lightbox.

That’s all for this week.
