For our final, Sean and I teamed up to make a functional record player. Sean had come up with this ambitious idea, are we surprised, and wanted to try the sound modules I used for my tribute card. I had already wanted to do something again with the sound modules, so I suggested we work together. I had such a fun experience working with Sean and I am ecstatic about how our project came out. I couldn’t have done it without him.
CONSTRUCTION PROCESS:
Day 1 we focused on brainstorming ideas of how this idea could even work. All we knew was we wanted it to simulate a real record player that would flip, playing a side A and B. We had to seek different sound modules to use because the way the one I used in my card would not get triggered to play the way we were thinking. It was a pull tab designed for cards. We started searching on Amazon for other options and found ones that involve light sensors. With that we began doing some sketching.
Honestly, I don’t recall of the initial ideas because there were so many, but we encountered struggles about order of events: on, light turns on, record spins, song 1 plays and how song 2 could be separated. I remember suggesting everything being on one circuit and having a delay in the track to move the needle which would have been used as an aesthetic. I just remember having many layouts that we realized would not be able to work.
Pictures from the prototyping process:
We had a hard time getting started and trying out these prototypes because we needed our box, pieces cut in the wood/vinyl, and all of our materials in order to get started. It was difficult to create any kind of fully realized prototypes because of the layers we needed and waiting on multiple materials. Our first attempt at a solid prototype was the night before we had to come to class with a prototype to show. We spent hours on to realize it would not work because of the placement of the battery and we got to a point of frustration that we had to call it quits for the night. We also did not have enough materials with us to make more attempts. I felt so defeated. Throughout the whole process I was concerned our project would not work even at all, but I wanted to see this through. That morning I worked at 5am and I was talking to my coworker about the project. Suddenly it hit me, and I immediately pulled out my sketchbook and drew it out so I would not forget. That ended up being our final result.
The way this idea would work is that there would be one circuit connected to an LED light and a motor, in order to signify that it was on and begin spinning the vinyl. This was done by creating a break in the circuit and using a switch to compete the negative side. On a separate, but connected circuit were the LED lights and sound systems. Each light was connected separately by the negative lines, however the positive ran together up through the box by a copper spike to touch the vinyl, then conduct through the copper needles and be redirected based on the position of the needle to the positive of either light.
At this point I was still nervous it would not work because it relies on multiple poor connections and if the lights under the box shut off even just a flicker the entire song restarts. We also had to work in a really small space. A lot of questions came up during the process: what could we do so the disk had to be flipped, how can our songs play at certain times, and why are things not working as anticipated? We were looking into ways to prevent conducting through portions of the disk depending on where the needle was places. Andrea suggested using clear nail polish. We ended up not using it and though we definitely still could have, we were already having difficulties getting the connections to work that it would have made things more difficult than necessary. I would like to revisit using that for other projects in the future though.
In the earlier design we thought we would have to box in the LED lights with sound systems so that the lights would not turn on both at the same time. However, we encountered an issue that light still happened to make it into the box through the cracks. We ended up leaving the cap on the sensors and placing the lights very close so the light could reach inside the cap. This way it solved the issue of light reaching inside and we did not have to box in each sensor. This also saved our ears from hearing the songs go off even more times than they did.
Once we had the idea constructed, it was working, but not well at all. Big achievement though. We ended up pausing for the night and coming back to it again the next night. We spent some time trying to understand how to get better connections. We were also having difficulties with the batteries in that it seemed we needed lots of pressure in order for them to work. I think we managed to short circuit and burn out a few during the process as well. Another issue was the disk seemed to be too heavy for the motor and the battery we were using. We ended up calling my brother to see if he could help us. He gave us advice on stacking batteries or using different types of batteries. We also glued these batteries in an attempt to hold better pressure. He also mentioned that the adhesive on the copper tape was likely creating connectivity issues. Using multiple batteries created problems with the red LED light because it could not withhold that much power. That was something I did not know could be a problem, so it is something I am glad to have learned about now. Ultimately though, this helped our project function better overall. Something else we did was we added rubber to the piece we put between the motor and the disk to create more of a catch for it to spin, which it was spinning fine last night. My brother suggested using pager clips on the needle to give it some weight and a better surface touching the vinyl. We didn’t like the look of that but at that point we just wanted our project to work better than it was.
SONG MAKING PROCESS:
This part was a very fun and creative process. I think this all came naturally. There really wasn’t a point where we weren’t on the same page because we were both open to so many ideas. We really just wanted to have fun by this.
For our first song we wanted to create something a bit more serious and entirely contrast that on side B. Sean and I both have experience with classical music and went in that direction. Around the time Sean came up with the name of our band he suggested wanting to write a song in Swedish and ended up composing Side A. I added in some vocals and improvised my guitar based on the melody. We listened to some Nordic music online to get an idea on what they music traditionally sounds like. We really liked the characterized sound of the bass vocals, drums, and both of their wind and string instruments used.
Side B was really a collage of everything we wanted to do. We did actually have a lot more ideas for it and we likely would have added more if we had the time for it. There was one day where Sean came to my house with all of his equipment, including a full drum set, a bass with an amp and more. We fit all of this in my living room and just had fun with it. I haven’t had too many experiences where music wasn’t taken as a serious matter where it could just be playful noise making, careless whether or not it was good.
We both agreed we wish we had more time to clean up our songs and record more. Yet, what we did get out of exploring programs was useful. I had used Garage Band on my phone for my tribute card, but it was really hard to do that on such a small device. We ended up downloading a program similar to Audacity called Audio Tonic on my laptop, watched a tutorial online and started messing around. Some of the prototyping you can hear in track 3. We found problems with the software in that there were difficulty picking up sounds, playing sounds without overdoing the gain, adjusting volume, and that tracks needed to be muted in order to record another layer. It became a guessing game for rhythm. This was an issue I had in Garage Band too. Out of frustration we started just jamming/ sound making for a bit and I happened to catch some really nice stuff that was placed into what is heard in Side B.
Since we had issues with Audio Tonic, Sean searched for another program to try called Audio Desk. He was able to set this up with a small microphone and play through earbuds so that we could listen as we were recording. We still had some similar issues with this program but being able to solve the issue of having no clue rhythmically where the track was at underneath helped so much. We finished Side B in Audio Tonic but created all of Side A in Audio Desk.
What did I personally get out of this project?
I feel a lot more experienced using “simple” circuits and general problem solving. I got to dabble into cutting wood again. I gained experience using alternative sound recording programs. And I worked on learning how to collaborate with one of the best partners I could have had.

PROTOTYPE 2:
Prototype 2 involves lights and a sound system. I really like plants and wanted to make meaning involving that. I thought it could be funny to create a plant that could actually talk to you. I used simple circuits and I used Audio Tonic again to put the sound together.
What would students get out of this lesson?
The idea in our lesson plan is that students would strengthen knowledge of materiality. They will learn about what makes an object have meaning/personal value and how that can be made to be expressed to others. Students can learn to seek value in the things around them. I think that the project Sean and I did was really ambitious, so I feel like a more developed version of prototype 2 might be a little closer to what I would expect from students.
As frustrating as this class can get, I am so happy with what I got out of it. It feels empowering to have learned to do things I never thought I would be able to do.
