Inspired by my hobby, I had wanted for a long time to build my own instrument. I combined this goal with a school pro - ject, which included planning and buil - ding this 3D object. To meet the requirements, the e-cello had to fulfill several conditions: it had to show the shape of my logo, be producible in a short time, be playable while standing, and be portable in a cello case. The main focus was the development of the sound pickup and its electronic amplification.
