And here's a youtube vid taken by the interior view camera showing the three daring industrialist uberhamsters exploring their new home, battling for supremacy and generally doing objectivist hamster stuff.

http://www.youtube.com/watch?v=dh1r_yTHoYw

All three are siblings from the same cage so I was assured they won't hurt each other. I was more nervous about airflow, although as you can see I've modified the tubing so that air is now piped into all 4 rooms instead of 2 (where before it relied on interior airflow to distribute fresh air, it's now manually injected into every living space.) After an hour and a half they're no less energetic, which is consonant with the original math indicating that the deep water air pump I'm using can sustain 15 hamsters. 3 is no sweat. Still, putting this whole thing underwater is going to be nerve wracking. I made sure to install a heater pad (red thing, in the rightmost room) that will be powered constantly from the mains so that if they need to get warm, they have a way to do it, just like in Hampture Mk.II.

Everything seems to be in order, just gotta add the water filter (using a water dish until then) set up everything that will be on the surface in weatherproof enclosures (the battery backup for the pump in case of power failure, the power strip that everything plugs into, the dedicated laptop for the livestream channel, etc.) we could have Hampture underwater and streaming live video within the week.

Also, I think I have a solution for resupplying it with food without bringing the whole colony to the surface; What about having one room that's not bolted down (probably I'll reuse Hampture Mk.II for this) on a long, flexible tube? With a handle on the enclosure I could reach down and bring that one room up to the surface, put more food in it, then sink it back down. That could be the food room.

I'd need to work out how much would be emitted and how quickly it will be carried away by the air circulation system.

[Mad Scientist !!Q11PG81nz2n No.3307773]

Is there such a thing as a port for a screw-on flexible tube so that I could expand the base without bringing it to the surface? It would need to keep water from entering both the enclosure and the tube until I had screwed the end of the tube into place. I can imagine a mechanism that would enable this, I am just wondering if anyone already makes such a thing.

(It would also potentially allow for an RC sub to safely dock with the station assuming I could find a way to motorize the rotation of the cap.)

I wonder if that type of plankton will do the job. I could ask the local biology department.

One of these days I'll have to email their bio department and see what they're willing to offer.

Btw, I was looking at this octagonal acrylic aquarium as a possible addition to the Mk.III colony; I could place two of them on the unused space on the platform, bolt them down, attach them via angled acrylic tubes, and make a natural terrarium inside of each. Like with LED lighting and live plants. A modest insect population would also provide a sustainable food source for the hamsters.

>>3307829

>>Many people have discovered this.

I don't claim to have invented algae bioreactors or biocoils. But historically every design for a bioregenerative life support system has placed the biocoil/reactor or hydroponics system on the inside of the habitat. As a single human being requires many tens of square feet of plants in order to meet his oxygen needs and remove the CO2 he creates, this winds up requiring unnecessarily large habitats. As undersea habitats obviously aren't mass produced (yet) their price scales exponentially with size, which is why most are very cramped.

My innovation is to design a system that functions outside of a habitat, as a chain of linked enclosures on the seafloor containing either wheatgrass (in which case watertight dryboxes with soil and overhead LEDs would be used) or chlorella algae (in which case transparent plastic cylinders, less resistant to outside pressure (as they don't need to be) could be used.)

Pic related; the algae biocoil in Lloyd Godson's Biosub I. He ditched it in biosub II because the outcome of the Biosub I project revealed that he couldn't fit a biocoil large enough to fully sustain himself inside the habitat. I don't get why nobody seems to have thought of sticking a larger array of coils outside of the habitat, freeing up more space for people. Plants and people have very different needs.

I deliberately placed the heating pad in just one room so that they can self-regulate their temperature. I don't know if they'll find it too cold or just right or what.

In Hampture Mk.II, two things I learned are that LED lights were a waste (ample light penetrates to that depth) and that the hamster was completely indifferent to the heating pad. The best explanation for this I've heard is that while human habitats are steel (an excellent thermal conductor) these habitats are almost totally plastic, an excellent thermal insulator. The interior temperature is probably dictated mainly by the temperature of the air being pumped in rather than the temperature of the outside water.

At any rate the heater's there and always on. If they need it they will seek it out, and if not they'll ignore it like Megafucker Supreme did in Hampture Mk.II.

Yes, but when I looked into how much power it could produce versus how much work it would take to build it, it didn't make much sense. The battery pack used for lakeside missions (no outlets out there) will have a 30 watt solar panel constantly feeding it, which as it turns out is about half what's required to fully refill it in the span of 8 hours, so it can't be used on a longterm basis but it will prolong battery life such that the habitat will be able to operate for two and a half days continuously rather than one and a half.

The pond is on fenced-in private property. The lake test will last a few hours or perhaps overnight and I will be present to oversee it.

Roborovskis. The paperwork listed them as "robo hams". Alas they are neither robots nor made of ham.

Since making the new threads I've had two donations, $5 each. I'd say over the entire Hampture program I've netted maybe $120 in donations and $100 from adsense. The project, all habitats from start to finish, has cost somewhere in the ballpark of $750.

OP, I've noticed that you have this whole thing bolted down to a piece of wood. Isn't that a bad idea? The wood will absorb water and decay over time, won't it?

[Mad Scientist !!Q11PG81nz2n No.3308679]

>>3308652

>>The wood will absorb water and decay over time, won't it?

Yes, but this project won't go on forever anyways. And the wood has been treated with sealant that protects against water. That should keep long enough for many fruitful missions.

How large are your Roborovski hamsters and are they sociable? What are the genders of the 3 hamsters you have?

[Mad Scientist !!Q11PG81nz2n No.3308713]

>>3308707

Each is about the size of a golf ball and all three are female. They are siblings as well, raised together, so I anticipate no issues with violence.

I build that microwave trap you posted. It burnt the shit out of my wrist. Good news: It works.

[Mad Scientist !!Q11PG81nz2n No.3308818]

>>3308808

I told you there's leakage. Some of the microwaves will get out the back almost no matter what you do, as you have a passthrough hole there for the power cable. A bit of shielding, even tin foil over that part of the waveguide goes a long way.

Got any pictures of the completed mechanism? What did you wind up using as a waveguide?

I believe that might purchase a bottle rocket, which would be just barely sufficient to lift a single infant hamster. This may have to be a generational endeavor.

So if you ever decide to upgrade your power supply, many apc battery backups allow you to hotswap batteries. probably not important, but if you truly lose power on scene for long time, or ever go testing far away from energy, you have the ability to charge an extra batteries elsewhere.

[Anonymous No.3308858]

As I said earlier, I dont have a cam. Feel free to not believe anything I say, But I ended up using part of a smaller old satellite dish.

I got really lucky with materials. My uncle is like a technological wizard. I just had to drive over and ask him for the parts. And also dissemble like 3 microwaves. (2 were broken).

I plan to simply save up for another powerpack like this one: >>3307943 and refit both with 78ah batteries. That will enable the habitat to run for between 2 and 3 days, likely longer with the solar array attached.

I'd return late in the evening when most are gone to retrieve the spent powerpack and put the freshly charged one in its place. Presto, continuous power.

Another test you could consider is how they react to situations.

Ex:
amount of food they eat, how often they drink from the water supply, etc. (how often they perform certain other tasks) vs. doing those same tasks underwater.

It would add even more interest to the project. :)

Make sure the hamsters cant chew their way out of it.
Would be damn shame.

[Anonymous No.3309383]

>>3309349
Made me realise - is there anything to stop the hamsters chewing away at essential components, like say, the heating pad?

Should you spray it withsomething that'll deter them from doing so?

[Mad Scientist !!Q11PG81nz2n No.3309389]

>>3309383

>>Should you spray it withsomething that'll deter them from doing so?

Already have, the same bittering agent typically used to keep dogs from chewing furniture. I used it in Hampture Mk.II also.

if a pod was on land, wouldn't the air pressure be same underwater as above water?. Or I guess since this is a sealed habitat, it would be whatever pressure you wanted anyways. nvm.

[Anonymous No.3309820]

If you want to lower surface dependability, why not include a dynamo that is linked to the running wheel?

probably not enough to meet the demand of the enclosure but well, it is a step into the right direction.


maybe that's something for future stages.

while you wait for the algea to grow, you should start a test row, and find out just how much electricity 3 hamsters produce on average, if they have nothing else to do than run on the wheel.


perhaps Mk.IV will have more hamsters, and more running wheels. You said the pump could keep like 15 hamsters alife, while consuming the same energy.

how many hamsters do you need to keep the pump oparational?
