In the lab, we have an LED dome that looks like this.
The teensy microcontroller that controls the array is faulty so I plan to replace it.
However, getting the old board out isn’t as straight forward as it seems because it abuts one side of the LED dome. As such, we can’t desolder and pull the board out easily. After consulting some Professors, it seems that the best way forward is to remove the bord by brute force! Below are the tools I used to excise the board.
With some careful maneuvering, I was able to successfully excise the faulty board without harming the components around it. Now we just have to solder in a new one.
Adding in the new board has its own set of challenges. Stay tuned for another update.
