Week 3: Electronics production

Proposal

This project took a bit of time to complete. While I had completed the soldering and milling the week it was assigned, getting the programing to work took a few weeks longer than i had anticipated. So figuring out the mill was super easy for me. the x y z axis was simple. Imaging the the left movement as the horizontal x axis and the backwards and forwards movements as the horizontal y axis was pretty intuitive. The z axis was simple enough to figure out at depths and shallowness from there. getting the board to be lit flat was bit difficult. But after figuring out where on the sacrificial layer was the most level location, milling went smoothly. Soldering is not a new skill for me, but it is one of my least favorite things in the world to do…I knew inevitable i would create a short or even worse heat the Tinny 44 chip to the point of breaking it, so i milled 3 board just incase. Turns out I either solder the 44 chip backwards, ripped the copper traces off, or shorted too many traces to repair the board, that those three boards weren’t enough. by the time i had finished soldering i had run out of time, HOWEVER, i was able to program the board with the help of Paloma and Calvin. I followed the instruction of both my TA and Brian’s tutorial linked to the class on the website, I was able to get the LEDs to blink and the programer to work. Thank you Calvin and Paloma for working with me on that. Programing the board was probably the biggest obstacle.
