Two attempts, one almost success.
The first time I made a textilo, it worked perfectly, all that was left is to sew everything on a T-Shirt, and I did.
However, later on things started falling apart: wires falling off, the circuit ripping in various places, etc.
I decided to remake everything, from the very beginning.
The second textilo worked just as perfectly as the first one.
I sewed it on the t-shirt and it was ticking very quietly, but it was still making at least some sound (better than nothing).
Overall, it did work at some stages, but the results were not satisfying.
