Build a miniaturization laser assembly, and miniaturize existing armor compomnets, as well as introduction of two new armor compoments, a death ray, and jet pack.

Stack 9 vanilla equiptment solar batteries into the into a 1x1 armor slot, 8 mk-2 batteries into a 1.2 slot.  Reduce, mk2 shield, laser, discharge, roboport mk2, and night vision to a 1x1 slot, reduce a exo-skeleton to a 1x2, and fussion battery to either 3x3, 2x2, or 1x1 without any performance reduction.

The jet pack and death ray, start out as 10x10 items which can be eventually be reduced to 1x1.  Jet pack will allow the player to fly over rocks, water, and speeding trains.   The death ray, abid a slow rate of fire, delivers enougth damage to single round any bug.

The resources needed to create the miniaturized items are fairly substantial, and the final assembly may not always work.  Probablity of success is between 25% to 81%.  Failure will result in an explosion.

The chain to create the items is make some cleaning solvant.  Then box up some mixed ore, grind the mixed ore to make gravitanium ore, and smelt new ore into gravitanium plates.  Take the gravitanium plates and clean them with the solvant, then turn the cleaned gravitanium into powder.  Finally box powdered gravitanium into an iron box with some additional iron for shielding and put that into a steel box for transportation.  The miniaturization ray, is also rather expensive but fairly stright forward to make.

To miniaturize an item, reprogram a few construction robots, disassemble a centrifge, slowly release the gravitanium into a centrifuge as it is spinning around inside the assembly machine.  That will create a massive magnetic field.  Within that magentic field zap it with the nuclear powered miniaturiztion ray.  If all goes well the item will be shurnk in size but not capability, if not, well I hope you are not close by and nothing importiant is close by.  The more the reduction, the more robots and gravitanium is needed.
 
Finally, major thanks to darkfrei for explaining how to implment jetpack!
