Specifications and Constraints

Music control functionality/Spotify interface
- The most important part of the project is that it has the ability to actually control my Spotify music library
Connection to speakers
- To be a worthwhile desktop piece, it is crucial that the device is able to connect to external speakers so that music can be played with good sound quality
Cassette futurism aesthetic
- The reason for choosing to go with a retro TV as the starting point of the project has to do with the cassette futurism aesthetic. I can control music with my phone or laptop, but it is more unique to do so with older technology
Physical controls
- I think that preserving the tactile controls in old TVs is significant when combined with a modern computer interface (eg. Spotify)
Form factor
- Since the project is meant to be desktop hardware, I do not want the final product to be too bulky or take up too much space. However, the screen should be big enough to properly display the music control interface.

Space
- After buying all the necessary hardware to adapt the Raspberry Pi’s display output signal to the old TV’s input, I realized that it may be difficult to fit all of it into the body of the TV. I have yet to take apart the TV to see how much room there is inside, but I think that I will have to fabricate an external enclosure.
Time
- With the end of the semester coming up and commitments to senior design, I will have to plan accordingly to make time for this project
Electrical Demand
- With all the electronics needed, it seems like there are multiple plug sockets required to power the project. I do not want to have to plug in multiple plugs if I want to move the device around.
Display Format/Resolution
- I have been able to get the Raspberry Pi to display on the TV’s screen but it is fairly low resolution. Although I expected this from a 1980s TV, I am not sure if the Spotify interface will be properly legible. I may have to play around with scaling in the software.
Budget
- I already have all of the main components for the project purchased and I am well under the $200 budget. The only remaining parts will probably be 3D printed, which can be made for free in the ITLL.
