KFETS Part 3: Prototyping 1

The stages between research and a final product can take a long time, with many iterations and prototypes in between. 

After obtaining all the parts, I connected everything with jumper wires and a breadboard for PCB-mount components.

After I was satisfied with how everything was working, I realized that I needed to make circuit boards to mount buzzers (responsive to shorts) and to mount the parts that run the meters. So, I learned how to make boards:

The first method I learned was acid-resist PCBs, which is how the two above were made.

After everything worked, I soldered together the circuit. After some troubleshooting, the prototype worked. I screwed everything into a sheet of MDF:

Stay tuned for more!
