How to Make (Almost) Anything

Embedded Programming

This week's assignment was to program the PCB that we designed using different programming tools. For someone with no background in electronics, this weeks project was definitely mind-boggling.

  • Software
  • Machine
  • Material
  • Hours 6

Project 07a
As Nadya mentioned after checking my connections, there was some soldering work to do before proceeding with the programming. After spending an hour or so doing that, I started with my first trial with programming. avrdude: safemode: Fuses OK (H:FF, E:DF, L:5E) avrdude done. Thank you. was the answer that I got everytime I tried using make program-usbtiny-fuses and make program-usbtiny in that order. After a few futile attempts, I thought I went back to replacing the resistor to 1Kohm and rechecking my soldering. Still no success.And then I went on to resolder my LED just to check if the orientation was right. Well looks like it was, but I still was getting the same answers and LED was still not blinking. So I thought I would replace my LED. I thinking I heated my LED too much, eventually one of the traces peeled off!. No choice but to re-mill the board.
Project 07b
None of us in the lab knew what exactly was wrong. So I thought I would re-mill my board and do the whole cycle again.
Project 07c
Unofrtuntley something was wrong with th end mill so Sara's board ended up looking like this.
Project 07d
My board after replacing the endmill. We are not exactly what's wrong. So this is going to be a work in progress.
