Do it yourself

I will wager, that at least 75% of what you need for that tank is laying around as forgotten dreams in people's yards. Find the art within you, you already have the passion.


What is the point of driving to 500 peoples homes per day, if you are just going to do it for wages? Think of it as a giant outlet store, where you can get anything you need for .10 on the dollar, they are just warehousing it for you. "The pleasure ain't the killing, but the hunt" [Hobo Jim]

Oh, my eyes are open. Just in the wrong neighborhood. Of my 700 houses, at least 500 of them have been built within my lifetime. That means a lot's going in, not much coming out. In the 200 or so days I've been slingin' mail, I've seen one hot water tank, one bed frame, and one exterior door on the curb. Slim pickens in Ritzyville =/

Could you incorporate the heavy duty steel shelving they sell at Costco (for less than $200)? The legs and cross beams are designed to lock together when the weight is applied. I don't know what the load rating is, but they are pretty beefy.

This entire stand is suppose to be sub-$200, and that's still my aim. I'll figure it out, just gotta do some learnin' first.

Happened to run across the following post regarding aquarium load and floor design by an engineer. Seems like it might be a good resource for you during the redesign of the aquarium. A little long but full of good stuff.

I'm happy to see I've already read that one three times =) My favorite part was right in Myth #1 - "You might have a whole lot more than 40 psf directly under your aquarium but that's okay because you didn't fill your entire room with aquariums either."

Umm...err... lol ;)

Ok folks.... how do I go "nano"?

If I have an aqueous suspension of powder can I use ultrasound to make it an aqueous solution of nano-powder?

Or would it be more effective to bombard the dry powder with the ultrasound so as to smash it up into nano or nano-like particles?

Just how big is a nano, anyway?

"Nano" size is between 1 and 100 nanometers. This is almost atomic sized. For example a strand of DNA is about two nanometers in diameter. Using a pulsed laser to shave these sized particles off a larger block is one solution. I don't know if ultrasound will be able to consistently produce particles this small without creating a mash of larger sizes too. The nano sized particles will be in there, but how do you separate them out?

Here is some background on the topic from the U.S. Government

Quote: Nano.gov article

A simple thought experiment shows why nanoparticles have phenomenally high surface areas. A solid cube of a material 1 cm on a side has 6 square centimeters of surface area, about equal to one side of half a stick of gum. But if that volume of 1 cubic centimeter were filled with cubes 1 mm on a side, that would be 1,000 millimeter-sized cubes (10 x 10 x 10), each one of which has a surface area of 6 square millimeters, for a total surface area of 60 square centimeters—about the same as one side of two-thirds of a 3” x 5” note card. When the 1 cubic centimeter is filled with micrometer-sized cubes—a trillion (1012) of them, each with a surface area of 6 square micrometers—the total surface area amounts to 6 square meters, or about the area of the main bathroom in an average house. And when that single cubic centimeter of volume is filled with 1-nanometer-sized cubes—1021 of them, each with an area of 6 square nanometers—their total surface area comes to 6,000 square meters. In other words, a single cubic centimeter of cubic nanoparticles has a total surface area one-third larger than a football field!

Perhaps there is a nano-sieve or nano-collander available?

So many substances are sparingly soluble in water and so the body does not absorb them but in a nano size can indeed be absorbed readily by the body. One example is the spice curcumin/turmeric.

I might not need to go to an area well beyond a football field...so perhaps I would not need nano but nano-oid sizing.

Unfortunately/Fortunately, at that size, substances behave and interact differently than their larger sized cousins. For example, gold actually appears red or purple depending on the size of the particles.

Manipulation via proximity to magnetic fields / electric current is used in industrial applications. There is also mention of CO2 "bubbling", but I don't know how that works.

Fascinating information. I'll study it closely as soon as I sober up.

Now as to that ultrasonic cleaner they use... that brand goes for 300.00 to 2,000.00. I just spent three dollars on some feeder fish for the feral cat's rain water bucket so they won't have to eat mosquito larvae all the time. It took me a long time to save up that three bucks so I don't think I'm going to be buying no three hundred dollar ultrasound machine. I'm a pauper.

I might be able to use a Mason Jar's Pickle Pipe ... its a plastic lid for a Mason jar that allows CO2 to escape but does not allow 02 molecules to enter the Mason jar. (Fermentation air lock in plastic). Its like a nipple with a very small hole in it. This turned backwards would allow only very small particles to pass but each pulse of ultrasound would be like a hammer ramming a suitable small particle through the nipple but not blocking the nipple with larger particles.

Uggh,
My front door lever spring latch device broke
The deadbolt to lock is separate and fine
Its the door knob lever device that keeps the door closed but no lock, just a typical a spring latch on most doors indoors.
Instead of turning, I use my thumb to press down a lever
Pushing the lever down was just moving the spring latch a little
Just gave out.
Even though the front door was not locked, separate deadbolt not engaged, could not get in because pushing down lever not moving spring latch.
Took lever device apart. a part is broken, whole lever device needs to be replaced
So I figure I have to replace the whole thing including the spring latch so get ready to remove the spring latch itself
I get to the metal faceplate on the side of the door , 2 Philips screws, 1 badly stripped
I struggle and struggle, it cannot be turned. sucks
The device I am trying to get out and cant, the spring latch itself that just moves back and forth to keep door closed, works fine.
If I buy a new lever, it probably wont match the old spring latch
Well I took apart my lever device on my laundry door and put it on my front door and works fine because the parts match
Not as nice as the original front door lever but it works fine.
Bought new lever and spring latch for laundry door, no stripped screws so new lever and spring latch on laundry door
Old laundry door lever and original front door spring latch on front door now

Stripped screws are such a bite. I am pushing down to turn to come up.
Opposite pressure, uggh.

Found an unopened can of Benjamin
Moore oil based semi gloss in the
basement started painting the downstairs
bathroom on Friday. I had forgotten
what a pain it is working with oil paint.
24 hours between coats, so this took
2 days for 2 coats. I have to say, I did
the whole thing, 2 coats, with just one
quart.

This is the basement door that's in the
bathroom. This house was built in 1854
and the door is original to the house.
It leads to a scary almost straight up and
down wood stairs that ends at a stone
wall at the bottom. It's scary for an adult,
for a kid it's terrifying.

Advantage in oil is it covers anything. In college some guys made a "to do" list on the wall with 1000 or more things in magic marker. College kid stuff, no serious damage but boy was the landlord POed. He made them try to paint it with the cheap laytex we had. Several coats and it still bled. Guy they brought in to fix it got some oil paints. One coat.
