This week's assignment was to design and mill a PCB with a sensor.

  • Software Eagle
  • Machine Modella
  • Material Copperboard
  • Hours 5
Project 01a
I designed Professor Neil's board in Eagle just to get a hang of the software. This time it was so much more easier. Milling in progress
Project 01b
Milled and soldered bord. Soldering was getting easier by the day!
Project 01c
After prgramming the program using the ccode and the make file and running the py serial, I connected my board to a copper pad to test if the step response was actually working. It seemed to be doing just fine. The values varied as I applied pressure onto the cpper pad. It was quite facinating to learn that this is the basic technology behid touchscreens. I cant belive that I'm actually learning and making such stuff!'
