SchitzoBot Emoticon Grin / Grimace Droid

Like this it is a happy bucktoothed grinning grasshopper face. Joy prevails!

But uh-oh! Now it is making a grim goat grimace! Stand clear!

Pressure Wave Percussion Thumper - for war or peace.

In war time this vintage percussion thumper will send shockwaves of rippling energy and matter - even through a vacuum - that you can focus right on your enemy's hull. Also you can thump your foe's resolve, percuss their sense of what exactly they are trying to accomplish. In peace time you can rig it up to your deep space tofu manufacturing machines, to thump the loaves into shape.

Intimidating Prosthetic Hand

Lots of space sailors, when they lose a hand, claw, or tentacle in active combat, like to rig up a hook or something in place of the lost hand, claw or tentacle. Why not consider rigging yourself up with this multi-use gadget if you lose an appendage? You can strike fear in the hearts of enemy crew as you (completely legally) board them and seize their cargo like a latter day Captain Hook. Except in this case you would be more like "Captain Masticator," or something like that. Also: It mixes up a sloe gin fizz quite thoroughly. You can use coconut milk as the bar lubricant for nice results.

Projectile guidance pipe w/ polymerized adhesive stripping

You may not know this, but a pipe can guide a small piece of metal in the general direction you want it to go if you make a small explosion in the other end of the pipe. Not quite as accurate or powerful as a laser weapon, but on the other hand, through some apparently massive oversight on the part of the galactic government, any idiot off the street can just go buy an explosive projectile guidance pipe and carry it around. Believe it or not! People consider it a basic right. In fact possessing one wins you virtuous brownie points in some religious systems. And while I'd hate to profit by selling potentially lethal explosive projectile guidance pipes to Gixrundian terrorists or mind juice cartels, or Vulcan invasion force scouts, or criminally insane robots, who am I to interfere with basic rights? All you have to do is bring 299 up-credits and pass a 10 milisecond background check. Also did you know that if the handle of your explosive projectile guidance pipe sort of falls off you can wrap it up with this nifty black polymerized adhesive stripping? Both functional and stylish.
