This is an Itty I with a mining turret, a civilian shield, a named survey scanner, and a power diagnostics unit. I also had an extra damage control module that I added, but it cannot run and keep the Iteronator cap stable with my current skills.
This terrible construction is highly inefficient but highly effective in my current use. I noticed with a Navitas that I was constantly having to run back to the station to empty the hold, and I didn't want to go to the trouble to jet-can and pick up with an Itty, or use a GSC.
My current system involves identifying a big asteroid, orbiting, and munching on the minerals. I leave the civilian shield running, which is able to tank 2 Serpentis rats at once. I can see my computer screen from the living room while hanging out with my wife, and so I just leave the Iteronator "GetRichSlowly!!!" chomping on an asteroid while I do other things. I do have to keep an eye out for times when more than 2 rats decide to ruin my profits!
I am sure that I could soon upgrade to a better mining method, but this is helping turn downtime into profits with minimal attention! (My inspiration for this method came from hearing about Chribba's Veldnaught.)
