Coming up on three months submerged.

...At which point I'll probably surface them and let them live on land for a while. I need to learn how to keep an aquarium ecosystem in preparation for adding fish, besides which, the habitat's essentially perfect. I haven't yet built another because Hambase Alpha is pretty much the best design I can come up with. It'd just be a copy of it. When I get the aquarium properly set up I'll probably only deploy Hambase Alpha, as the camera's gonna be focused on that anyway so there's no point to having more habitats cluttering up the aquarium, I'd rather make room for the fish. Still waiting on donations for aquarium plants, a water filter and a catfish to eat the algae.

Demonstrating the Aquabubble

The Aquasphere, being modular, can be reassembled either as a spherical unit with two domes, or as an igloo shaped micro habitat with a flat 'floor' and three legs that support it up off the bottom. It can be operated either in ambient pressure mode, or (with a second air hose carrying exhaust back to the surface) as a true 1atm hab, with internal pressure identical to the surface. In sphere mode it's intended to be supplied air from a small scuba tank and carried along on dives, but with two tubes it's also a proper pressure vessel capable of being lowered, like a bathyscaphe, to depths of up to 100 feet. The only other habitat in the Hampture project that was capable of 1atm deep water deployment was the very first prototype. The aquabubble, being intended for portable use and for being carried along on scuba dives, is supplied heat not by electric resistance pads but instead by nontoxic "lil hottie" chemical handwarmers which provide warmth for around 3-5 hours.
