I tried it to organize my circuit, but, failed.
The reason was I lost a part, 100k resistance, ohm.
So If I could get the a part, I will finish it, If I don't , I'm not gonna pay one more.
Any way, It was good practice to doing something micro with my shaking hand.
It made me to concentrate to something.
And It was good time, that gave me a time to Organize my theme for studio project.
