Zachary opened the briefcase and unfolded the schematics on to the workbench. They were vague from an engineering standpoint, and not quite up to the mission at hand. This sonic weapon, which was entitled Sonic Disruptor, operated using mainly just a powerful sound core and a lightning core to sufficiently power the Sparker to create a high-power sound in a frequency particularly sensitive to the human ear. Zachary pulled out his engineering books, a pencil and the task requirements and began looking at how he could execute this plan. To take out the hosts in question he estimated that he would probably need a couple more orders of magnitude of power. However, cross-checking this with the sound core reference, that kind of power output would require a sound core beyond the quality or size of anything he could salvage. He could always link up several sound cores, but then he could run into problems with resonance, and the multiple parts.

But there was a way around the problem. He did not have to use a sound core to produce sound. Instead, he could use a wind core, for sound is merely the compression and rarefaction of air. Wind cores have the benefit of coming in much higher power outputs than sound cores, but at the same time they don't naturally make sound waves. In order to make sound waves he would need to pulse the wind core. Fortunately, such a solution is as simple as applying an AC current of the desired frequency and passing it through a diode. On a separate piece of paper he began sketching out a potential design. The trouble would be acquiring the AC current and voltage. He considered for a while using a rotational inverter, but then he had a better idea. He could take an oscillator used in some radios, which is perfect because it operates in the audible frequencies, and use that. It doesn't have a particularly high output voltage, but if a sensitive Sparker alloy is chosen then that would be no problem at all.

Once he had the functional components figured out he then worked on getting a proper housing. This would be no trivial task, as the stresses and vibrations on the device would be enormous. However, the schematics given did indeed cover the structure of it, although Zachary would have to make it even more robust. The air core would be attached to the rest of the device by a sort of spring, allowing it to move with some freedom without shaking the rest of the machine apart. The rest of the device would be shaped like an inverted bowl, heavy and made of metal to minimise the shaking. The shape would give it stability, as well as reflecting the sound off it. For the power Zachary wanted he would have to be sure to thoroughly weld and fasten all components in place, for if it were to shake apart mid operation that could spell ruin for Mathias, and by extension himself.

The final matter would be the trigger. While the schematics specified a wireless triggering mechanism, such a component would be too complex for him to build a fully reliable wireless system in such a short time-span. Instead, Zachary opted to use a switch on the end of a long cable, which he would have wound up on a hook on the device for transport and storage. As he went over the design again, tidying up numerous details, he found it funny how similar to a discus or Frisbee it appeared. He supposed that, if he built it solidly enough, it [i]might[/i] survive being gently thrown like one. That would be a good way to get some distance between yourself and it in short notice. Except then he realised that the cable would get tangled, which may cause problems.

With the design complete, all he had to do now was build it. He looked briefly around the workshop to see what it had before taking the trap core out of his pocket, pointing it at an empty patch on the ground and pressing the button. With a burst of expanding air, flash of red light and the clanging of metal, Zachary's own scrap and his tools appeared on the floor. Putting the core back, he rubbed his hands together. He had work to do.
