I have some delay with this project because I still have preparing my new cave and tools. And work for my job :)

I have finished some quicks projects before too.

- one tester to measure kilovolts.

- one controller for the shaker and the resin scatter.

- touching again BJT amplifiers (pre and power) a little and learning about speaker, triodes and pentodes.

- welded one frame to mount trifasic motor and grinder
