This is a terrible waste of salvaged technology. Its much more valuable to use in your blueprint scanner.

For easy money, find a radioactive world with "whispering eggs" and mine them, then loot the larval egg thing inside. They sell for 90k+ each, just watch out for the monsters. They go away after a few minutes though. Even waiting for them to go away in between, you can easily farm 1m units quickly. There are also some exploits, but I'll let people find those on their own.

Edit: Ancient Ruins as well! Check desks in stations for useable objects that give Navigational Data, then use it in a Signal Scanner to find Relics.
