Anime Baka

Anime - Japanese Animation
Baka - Japanese word for idiot or fool

Loosely put an Anime Baka is someone who's crazy about Anime. However interpretation's may vary. I tend to think of Anime Baka as meaning something like drooling fan boy/girl.


Anime Baka Contact

Wrote this a long time ago. Too short for an article:
Perverted - Hentai in Japanese. But the word pervert means deviation from normal or accepted. So, how can all guys be perverts?

Did you ever notice that the sex scene in the movie is generally at about the same realative place as the guitar solo in a song?

Re-Floatation Device


I have been working for several weeks on a device to refloat ships automatically. The device I came up with has other applications as well. The current device provides approximately 2lbs of bouncy, takes about fifteen minutes to completely deploy and may also produce a stream of bubbles once fully deployed. When it fails to deploy due to manufacturing error it simply produces a stream of bubbles. I have never had a device fail to deploy when properly installed and void of manufacturing errors.

At the Petaluma Hobby Expo I demonstrated the new technology and we did some testing which failed when the float was deployed upside down. I don't have a current video, but can probably produce one soon. Video was shot at the Hobby Expo, but not by me.

Current State of the Art Design

This is my current evolved design. It uses 0.5oz of baking soda / citric acid mix which is twisted in a piece of paper towel. The paper towel should be cut to about 2" wide and about an inch longer than the bag is wide. I used strips of masking tape secure the center portion of the wrap (not shown in picture).

2011-02-22: I think cutting small holes in the paper towel for CO2 bubbles to escape will be beneficial. I think this can best be done after the wrapping of the mix is done. Just punch some holes with a xacto.

Holes are made in both sides of the ziplock back and the paper towel ends are pulled through. The bag is closed so that most of the air is removed from inside. Then shoe goo is applied all the way around the paper towel where it exits the bag but not covering the ends of the paper towel. The intent is to provide a good seal between the paper towel and the bag. Optionally the ends of gell caps can be put over the paper towel ends to protect from water splashes and delay activation, they should seal in place with the shoe goo.

The gell caps will add about two minutes to the time to deploy the float. You can find them for about $0.06 at health food stores. I have also experimented with filling gell caps with the mix. This may be a good method to provide a boost to normal floats. A couple of these strategicly placed in a normal float could help get it past weeds or overcome a partial deployment.

Shoe goo is then used to seal the ziplock itself. I have found that most ziplocks will leak CO2 gas, sealing the bag end prevents this. Perhaps double locks would work more reliably. Sealing also provides a tough place to mount a string for tying the float to your hull. I usually make two small holes at an area where the shoe goo is and put a string through both holes. This is secure enough that I've never had any issues.

This unit has double wicks so that water wicks through the paper towels to the mix faster and more reliably. However this design also has two exit points and that doubles your chances of a gas leak. Sealing these exit points is critical to keeping the gas from leaking out.

It is very important to keep the zip side of the bag as the bottom. When mounted in or on a ship the seam should be down. In this manner if there is a leak the majority of the gas should vent to the inside of the bag instead of to the outside. Bubbles venting through the wick ends are a serious problem. This should only happen when the bag is completely full of gas. The other point is that if the bag is oriented with the seam up, any water pooling inside the bag will pool at the top end and not near the backing soda mix.

In any event the zip seal should be oriented down for best and most consistent function. The easiest way to orient the float is to secure it to the keel with a string.

Now how many or how big of these devices you would need to float a ship depends on how much your ship weighs under water. Each quart sandwich bag produces about two pounds of buoyancy. A gallon size freezer bag would produce about eight pounds of buoyancy.

A large ship could have freezer bags placed fore and aft on pop out deck sections tied to the keel. When the ship sinks the bags inflate and pop out the decks and then the ship suspends between the floats with sixteen pounds of buoyancy. If the ship is well balanced with some regular foam so that it weighs less than sixteen pounds under water, this will do the trick.

Another idea is to use one of these float bags as a rerival float or in combination with one. With two pounds of buoyancy pulling the float line up it would almost certainly deploy through weeds and whatever.
