Bases

Here we discuss the optional idea of using bases in water wars. In this forum, we talk about designing/building them as well as other things like windows, roof coverings, turrets, and the protection of the base itself.

Why is blk water basic instead of acidic?

Recently I came across a brand of water called blk, named for the black appearance of the water caused by the addition of fulvic acid. The manufacterer's website states that it is "exceptionally pure artesian spring water" with the addition of the company's blend of fulvic and humic acid. Now, we all know that the PH of pure water is 7, but if we add acid, wouldn't that make it more acidic? Apparently not, seeing as the manufacturer's website also states that the PH of blk water is 9, making blk water more basic than regular water. I would think the fulvic/humic acid's addition would make the PH acidic, not basic. Can anyone explain this?

Anyone tried a (true) UV LED based moth trap?

I have also commented on a seemingly related old dead thread but hope for better luck here. Firstly, did anyone ever make any progress with building and successfully using an LED based moth lure/trap? Secondly and if yes, any advice? I am currently in the process of building a lure/trap that will use reflected wavelengths (interchangeable LED head) based on the principle that Moths (as pollinators) and flowers (as pollinatees) see and reflect UV light respectively and if that is true then surely i can take advantage of this to build a targeted trap to trick the moths in. note i will be testing UV wavelength (365nm), violet (400nm) IR and white LEDs.

If I bought a rechargeable 4R25 Battery, How many solar cells would I need to keep it charged? ?

I'm building a dog house which the base will be 9-10inches underground, which helps with the build up cool dead air at the base to help keep the house cool. I want to use four(4) computer fans to help ventilate the house from the base where the dead air resides. Near the roof of the dog house will be ventilation holes for the dog, in fact I may use another fan to vent out the hot air. I was hoping that I could use some silicone cells to keep the battery charged, but not sure how many I would need to keep it charged. if it requires too many I may stick with recharging the battery in the house or using a 9v battery for each fan and swapping it out here and there.

At the moment I have my tank mounted under the front barrel by way of a home-made rack. This works, but messes with the balance of the gun. any tips or links appreciated.

Dude plans to jump from a plane and land on his belly. Really.

Jeb Corliss has leaped from buildings and other places in a single bound. Now, he plans to do it without the aid of a parachute.Corliss, who is a base jumper, has made jumps in 16 countries and five contents, more than 1,000 in all, from the likes of the Eiffel Tower and Golden Gate Bridge.His latest venture is trying to jump from a helicopter and land without using a parachute.Corliss says he’ll wear a wing suit, which makes him look like a flying squirrel. He plans to landing on a specially designed runway he designed. It will cost up to $2 million. Once he gets the funding for his project, he says it could take up to four months to actually pull off.He added, “A wing suit, basically, is fabric that goes between your arms and between your legs and it changes the shape of your body. So you become, in essence, a flying squirrel.'He explains that he plans to land on his belly, suggesting, "œImagine an aircraft. Aircraft don't land on their tails, they land on their bellies. That's exactly what I'm gonna become. I'm gonna become an aircraft. I'm gonna be landing on my belly.Why in the world would Corliss try this?"œI wouldn't say I'm doing this because I'm a thrill-seeker. I'm a person who has dreams and my life is based on making those dreams come true. And that's what I focus on."

Water Bottle (Nalgene/Camelbak) Repair

My Friend,                      I decided that I did not like the color of my Camelbak water bottle. I had it hanging from the strap on my backpack as I was walking to class, and thought that I might do something about the color. I then proceeded to throw myself off of my ripstick, squarely on my back, so as to hit the bottle against the ground and break it, thereby creating the necessity of buying another. Well, it worked, and I now wish to make amends. (Long story short, [despite my previous alibi] I accidentally fell on my Camelbak water bottle, and put a breach in the base/bottom.) How might I repair this without the use of fire, (I am a little wary of melting it and releasing undesirable chemicals into my drinking water) duct tape or some other highly unsavory method of repair?

Well, my front yard is currently supported by piles of rocks where there is a ditch next to it, however only when there is heavy rainfall that the water passes through the ditch otherwise its empty.  The piles of rocks were placed one onto the other and these were never mortared and neither has a good base.  So, I have a huge amount of stones in my yard that I wanted to get rid of and also the quality of the soil where I live is very poor as it is like mortar when humid and blocks of soil when dry which I was thinking of using as backfilling. My question is how can I use the existing rocks to rebuild the retaining wall well, solid and also have a good look. By the way I live in Mauritius where the climate is humid and I live rather close to a mountain and river and the rocks are lava rocks meaning very hard. Please give me instructions on how to make everything from building the trench to finishing the wall and the tools that will be needed. thanks

Basics of Recurve Bow – How Do You Make One?

Would you like to learn how a recurve bow is made? There are a lot of people before you who have also tried to learn how it is made. There are people who are doing it for economic purposes and there are also those who just do it for the purpose of customizing their bow based on their personal preferences. But whatever the reasons might be, there is no denying that making your very own bow will give you a much better understanding of archery as a whole. Before you get around to make your own recurve bow, first, you need to be familiar with the various parts of the bow. For you to do this, you have to check out diagrams and plans in order to build recurve bows. These diagrams and plans can be bought from the local store if there is a bow manufacturer near you and you can also purchase this online. There are some diagrams and plans that are also available as the part of the set that contains all that you have to learn when it comes to making a recurve bow. In case you don’t want to buy one, there are also diagrams and plans that can be easily downloaded online without any charge? Take note that you are trying to undertake the hardest project in the field of bow making so you will need to get all the help you require for you to be successful in your endeavor.

Can a photo finish image produce a false result in a race or other circumstance?

Whether a 100m dash, a cycling race, or boats, cars or motorcycles going in excess of 200mph many times these close finishes are determined by high speed photo finish cameras or even less accurate low speed digital video. My question relates primarily to alignment of the camera in relation to the finish line but also other variable such as the surface of the finish line which could be either crowned or banked. Racers crossing over the line a few mm above another just because they are on either side of the centerline of the racing surface. Water finishes produce even more variables. Using a simple bike race where bunch sprint finishes are common with speeds approaching 40+mph I would place a bank of 9 (or 3) cameras on opposite sides of the finish line. Each camera should in theory produce a slightly different image of the finish with variable determinations of outcomes and results based on the resulting images. How would a judge or anyone determine the "correct" image and true result having only the digital picture? Second - of the photo finish images I have seen it seems the finish line is rather subjective? Is the actual finish on or more frames before or after the determined finish? If photo finish and photos in general admissable in court (myth???) how often is the perpective of the camera being judged considered? i.e. Someone who is significantly off the perpendicular snaps a photo producing an image that is quite different from another person's who is at a different angle in relation to the finish. Thank you!
