I forgot to mention in the last log about the development of puff switch support. The objective was to show the initial ideas of the development of this support that ended up influencing the tool developed as a final result. As it can be seen the development of this support was very artenal ( to fix the wires even hot glue was used hahaha). I had so much fun doing this support hahaha. I hope I have been able to show the reason for the construction of this tool.
