Transcript

you first started doing more engineering type stuff with uh Arduino boards at punch through design which is an SF engineering firm what are just from your memory there what are some cool things you built there so the thing is I I went to add words to like a vocational studies a year and there that I didn't care much for advertising but I thought it...

Questions & Answers

Q: How did the speaker come up with the idea of an iPhone case with retractable guitar strings?

The idea was inspired when the speaker was strumming their phone's charge cord like an air guitar and thought about creating a mobile guitar experience.

Q: How did the speaker overcome the challenges of programming and connecting the sensors to the microcontroller?

The speaker had some basic programming knowledge but had never programmed an iOS app or worked with capacitive touch sensors. They tackled each challenge step by step and learned as they went along.

Q: Did the speaker face any difficulties in making the strings taut enough to play like a real guitar?

Yes, using arm tension was not sufficient to create enough tension in the strings, resulting in a subpar playing experience. The speaker speculated about using a case with built-in tightening mechanisms but acknowledged the challenges that would come with it.

Q: What motivated the speaker to complete the project despite the difficulties?

The project was a school assignment with deadlines, which added a natural pressure to complete it. However, the speaker's motivation came from seeing the potential success and realizing they could actually pull it off.

Summary & Key Takeaways

• The speaker's interest in building and programming led them to create an iPhone case with retractable guitar strings as their first hardware project.

• The case uses capacitive touch sensors and a microcontroller to detect when a guitar string is touched and sends a signal to the phone to play the corresponding sound.

• Despite the difficulties faced, the speaker did not give up on the project and found motivation in the potential success and the satisfaction of problem-solving.
