China is definitely the master of IP theft.Oh for sure, it was just interesting that Neptune merged with ecotech in PA but they aren't even utilizing their assembly lines here in the states. My guess is that these boards are so simple that turnkey manufacturing overseas is greatly cheaper than it would be to do in the states. Or there could be a line capacity issue in PA and adding new products to the line wouldn't be feasible. Gotta be careful with overseas manufacturing, you open yourself to counterfeit part risk since they control part sourcing and may not be as diligent in that process.
Many companies take part in that word play "assembled in America". I don't know when that became the norm.
I'm trying to think back, for over a decade I've been good friends with 2 of the 3 previous owners of ecotech. Circa 2012 we collaborated on a new vortech pump design. I hit it off with Justin and Tim, to the point that I try to go spend a few weeks each year hanging out in Pennsylvania with Tim at his house. Our friendship doesn't revolve around ecotech or the industry, we're just good buddies that share other common interests. During the last visit, Tim, who no longer works for aperture, took me to ecotech to visit with Justin.
All that to say that when I was there I was given an impromptu tour of the facility post merger. I wasn't particularly interested in a tour and mostly went along for the ride. I can say that on this particular day they had people on the assembly lines building both ecotech and Neptune components. I don't recall them assembling apex "brains" but did see them putting together eb832s. Surprisingly, me, being intimate with the insides of the eb832, I didn't pay any attention to the pcb design and if it changed since the last iteration of integrating meanwell psu's.
I do know that traditionally neptune circuitry revolved around 5v references for their logic and ecotech utilized 3.3v reference voltage.
I can't speak with authority but I'm under the impression that Curt was the driving force in circuit design with all things neptune and followed a more industrial design while ecotech employed engineers with a more modern approach. With the dos qd and mxm adopting the more modern 3.3v design and sleeker circuit that mirrored the ecotech and AI stuff.
In terms of electronic hardware, I can't speak smartly as to what they pulled in house and what they rely on China for. I'd speculate that everything has to make financial sense and if it ain't broke don't fix it.
I don't know what or if they plan to roll out a new generation apex. As of lately aperture is only interested in maximizing profits and that seems to revolve around rebranding existing products and expanding beyond reefing. But if a new apex is on the horizon, I would imagine they would try hard to do as much of the manufacturing in Pennsylvania and try to safeguard their IP.

) If I had all the money back I spent in reefing to start over, my first purchase might be the duet. Auto water change to start and switch to kalk and calcium reactor when it's time. I'm gonna need 2 continuous pumps eventually and it starts my controller build out.
