I see your point. I can remove the gun, however, the bracer is really more or less a iPad mini type thing with highly advanced processors. Think super computer. It's only real abilities is as listed, provides power to machinery and helps process designs and such faster than anyone could.

[s]it can also play angry birds with 0 lag and unlock all teh IAP's[/s]
I do see your point on the gun though, perhaps a pistol? Or hell he could just make a gun himself.

You could just bring a laptop or something with you instead, and just make it more advanced while in Aurora through upgrades if it's just a computer so to speak. 

Eventually, you could just develop the bracer while in Aurora since it does count as an invention.

The problem is just this: The Bracer simply wouldn't exist in Earth because of the lack of technological advances, and because of the limited availability of resources for the common people- especially an insane person. He just wouldn't be able to make it. In Aurora? Yeah, he could. It's a fresh start with countless resources and possibilities, plus he has his powers.
