When I tried to make it more permanent
I'll take any advice you guys have!
Please explain what you did.
Please explain what you did.Avoid idiot Fritzing diagrams, as they are usually confusing and misleading. What is the black thing labeled "VREG" and what are the associated pins?

About my question about resurrecting the pro mini? Is it doable?
