A buzzer sounded, signaling the end of the cooling chamber's cycle, and Yelgir looked up from his workbench. As he walked over to the cooling chamber, he had to put his hands into his pockets to keep from rubbing them in anticipation. If it worked correctly, the TnT would greatly increase Dark Abyss' fighting chance. Not having to aim down the sights would allow soldiers to stay in cover while firing, and also make it easier to shoot while moving quickly.
He opened the door, and pulled out the small device. It was shaped somewhat like a laser sight, but with the end closer to the shooter tapering to a flat rectangle. Yelgir clipped it onto a rifle he had placed beside the workbench, then lifted the weapon in his arms. Pressing a button on the side of the TnT, he established a connection between himself and the device. An image of the wall sprang into his mind, and Yelgir was momentarily disoriented as this third eye appeared. It moved independently of his other eyes as he shifted the weapon, and a red dot marked the location that would be shot if he pulled the trigger. Modern "smart" weaponry could transfer data into the TnT, and detect variables such as wind speed, projectile weight, and gravity for the current environment, compressing years of training into a dot that showed exactly where the bullet would hit.
Yelgir cycled through the different controls for the device: zoom, night vision, infrared, even an ultrasound function that allowed limited vision through solid objects. It appeared to be working well. The night vision was a little screwy, flooding his mental eye with unnecessary brightness. He would have to work on that, or turning on night vision mode would ruin a soldier's actual night vision. The small android pointed the weapon behind him at the the far wall, closed his eyes, and read in perfect detail the instruction label for the access panel.
There was one thing left to do, besides fix the night vision glitch, and that was to figure out a way for a non-android soldier to use it. The current plan was to have an overlay on the helmet or an eyepiece, but he was trying to decide on a way to use the TnT's controls. He had thought about putting buttons on the device, but then the size would have to be increased, and the soldier would have to move one of their hands from it's proper position on the weapon to change view modes. Another plan would be to have voice commands, but that would betray their position, as well as the possibility for confused signals if two people had near-identical voices.
He paused in his thinking, and raised a free hand to his ear, an involuntary motion that displayed a new idea. One of the humans on the ship, a fellow named Jason, had a suit of body-armor that reacted to his thoughts, springing into position by mental command. If Yelgir could figure out how that worked, he might be able to replicate it with the TnT.
