W19 PROTOTYPE NO.TWO from the inside

This week I made my second prototype. I want to focus on the biggest problems first which are the connection point, so I let the other parts like tuning parts the same to save time.

This time, I tried to think the reverse. Prototype one is trying to trap a tin from the outside. This time, I'll try to make it inside. These are the progress of my prototype two and results I got.
