My user testing for the DIY Disco Set revealed that the project was generally intuitive and easy to navigate, largely due to the instructions page I added and the exploratory nature of the buttons. Users were able to understand the mapping between controls and the resulting effects without much guidance, which speaks to the project’s accessible design. However, I think there was noticeable confusion around the vinyl mechanism. The instructions I wrote mentioned that they should spin the vinyl to start dj-ing, on a mechanical perspective this was supposed to just jump start the motor and then it would start spinnning on its own, but users continued to manually spin and touch it even after the motor had taken over, unintentionally disrupting its movement. This suggests that while the concept was understood, the transition from manual to motorized spinning was not entirely clear. To address this, I think the instructions could be refined to emphasize that spinning is only required at the beginning, and clearer visual feedback, so such as an indicator light or animation, could help users recognize when the motor is engaged.
