As part of our first project, we were given the task of connecting a Piezo disc to an amplifier/speaker. The basics of this project included: soldering the red and black wires to the mono audio jack, then soldering the other end of the wires to a Piezo disc, and then connecting that to the AMP.
Step 1. Solder the wires to the large silver mono audio jack pictured below. This part was relatively easy for me given my previous experience in soldering; however, I did encounter an issue when I tested the connectivity of the wires to the mono audio jack. Unfortunately, the red wire was touching the black wire area when the case was enclosed causing connectivity when I touched the red wire and both the audio jack parts together, which shouldn’t have been the case. It should only be connected when touched to the bottom of the audio jack.
I solved this issue by using Electric tape which protected the wire from touching any other metal when enclosed by the capsule.
Step 2: Involved soldering the red wire to the white part and black wire to the back. This was easily achieved by soldering some wire onto each side, so all I had to do was just connect the two and add a little more solder to it. The soldering wasn’t as clean as I wanted it to look; however, it still did the job just fine. Just for extra precaution, I attached electrical tape to the wires to protect them from bumping into each other and possibly causing interference.
Final Product: Looks pretty good if ya ask me (:

Overall, this lab was cool, but perhaps the coolest part of the lesson was learning that speakers can be turned into microphones, and microphones can be turned into speakers. When Antonius first brought that topic up, I was gonna ask if you could then make your headphone or microphone into a speaker, but thought there was no way this is actually possible. But after watching that video, it was really cool to learn I was in fact right and that you could do this with nearly anything. I’m really looking forward to this semester and letting my creativity soar.
