The probes were impressively designed. Master Benedict Cortez only spent a short amount of time on their design, but his deep understanding of engineering along with his amazing understanding of energy allowed him to whip up a device that reluctantly met all of the criteria.
The most important demand was that it could survive the hostile environment of the upper reaches of a brown dwarf star. The second most important demand was that it would remain as obscure and unnoticeable as possible.
Under normal circumstances, Master Benedict would have preferred to design the probes and each of their individual components from the ground up, but he had opted to license existing probe and component designs to save a lot of time.
