* Plan meeting times with Reto

# 2022-09-22
* Meeting with Reto
* Testing measuring magnetic field when CPU is stressed out
  * No real change measurable

# 2022-09-23
* Test out multiple speakers
* Test measuring magnetic field of speakers while playing sounds
* Research functionality of a speaker
* Start work on the project plan using pgfgantt

# 2022-09-25
* Another test with a speaker
  * No change measurable in magnetometer even if I can see the coil vibrate
  * I assume the change in the magnetic field is too small to be measured
* Finish project plan

# 2022-09-26
* Test Magnetic Field of Laptop CPU
  * I can clearly see the spikes
* Another try on the Raspberry Pi
  * Still nothing accurate
* Research other solutions
