I have a 14000 rainwater tank, and like to find a way go clean the debris from the bottom potentially recycling the disturbed water - so there is minium loss i have a ready supply of compressed air near by.,.,. can any one devise perhaps a venturi device that is easy to build, runs on compressed air and effectively vaccuums the muck from the bottom while recycling the caputred water....

If I were to have 2 seperate buckets, one with ground and the other with something like 9 volts nothing would happen because the 2 bodies of water arn't connected. If I were to join the two bodies of water using a wire would electrolysis take place?

I have recently acquired a 25 litre compressor on which the motor was seized so my plan is to replace the motor and pump with a couple of fridge compressors however the tank is more than 10 years old and although I cannot see any damage is their anyway to check it is safe to pressurize to 8 bar? it has 175PSI stamped on it so I assume its designed with that as the maximum working pressure but I want to know if I can get it checked as I don't want to blow myself and my garage apart if it bursts I'm in the UK

Hey guys, this is my first time on the forum section of the instructables! Not a bad place to be, really. So here's the thing. I have this old scooter that I've had for as long as I can remember. It was the very first thing I rode that was powered by a motor and my father bought it for me so I could get ready for my first motorcycle (Which was sadly stolen about a year ago :/). Last year, my dad went back to our hometown to visit family and he brought it back with him, but there was one problem. We have no gas tank for it. I have NO idea where it could have gone or why it wasn't brought back. Oh well though. I have this scooter, the same as Wesley666 does. I'm having trouble finding the gas tank on my own. Notice that there is a gas tank that I took from a weed eater just to try it out. But I'm not sure it would work out very well. I mean, look at the size comparison between the two? I also want to keep original parts on this nostalgic machine. Sorry if the pictures are oriented weird, but these are taken with my phone.You can see from the thread posted above there is a picture that shows a blurry close up to the gas tank and I can't really tell what it says. "Something EBR Motor". Long story short I need to get that gas tank, maybe even the gas line that comes with it, in order to get this thing working again. Does anyone know of the brand name of the scooter so I could get the original parts I need?

Hi, I have coffee machine with small water tank. i want to put large water tank next to it so i would not need to refill it every time. my problem is that the water tank in the machine is not sealed, so if i put more water with a hose from bigger tank it will spill out.. How can i create bigger water tank next to it so the smaller tank will refill automatically? Thanks,

Some friends and I are looking to make some projects, mainly air powered. We have been looking for an air tank to hold the pressure before we discharge it but have been having problems finding the exact part. I have found lots of the air tanks to fill tires and stuff like that but I need something to hold a good amount of pressure and let it out in one big shot and can be charge with a normal car tire air compressor. -I need to know the exact name this items goes by. (Just "air tank" gives me the tanks for tire inflation) -I need to know a webite or store to purchase them at. (Home Depot or Grainger by any chance?)

I was think what was better? a Small tank with a higher pressure? or a large tank with a Lower Pressure? Of coarse if you had a small tank you gun would look better. This is how air rifles work... you break the barrel (push it down) and that push a pump in to a small tank at a high PSI, Thats why its hard to break the barrel. I was also thinking that if you had a Higher PSI in the air resivour it would release quicker?!. What do you think?

Alright fellow instructables, here's the lowdown: I'm currently attempting to build a hand-held flamethrower that you only need one hand to use, sort of like a pistol. However, when I was looking at a diagram for a regular Army flamethrower, I realized something: The fuel tanks on the flamethrower werent pressurized, and the fuel was pushed out using a pressurized tank that was fed into the fuel tanks. Now here's my question: Because I'm just trying to make a little hand-held that I DON'T need to shoot 50 feet, can I skip the pressure tanks and just jump to a commercial fuel source, like one of those miniature camper stove fuel tanks? Thanks Outdoors!

I am creating a custom fish tank stand from 2x4s and sheet wood. I plan to paint it black but I ran into 2 problems when I decided I didn't want the hood that came with the tank. 1) The lighting. I have a pretty good history with LEDs so creating the lighting will not be too hard, only real issue I run into is sealing the lamp. I plan to use an acrylic sheet with holes drilled for the white and blue LEDs. White for day and a row of blue for moonlight on a 3 way rocker. I just dont want water to penetrate the holes from the ports for the light to damage the components. 2) The filter. This is where I am at a loss. I plan on making something similar to this: http://tinyurl.com/fishtankdesign But I have no idea how to an external filter rather than one of the regular table top aquarium ones that would not look very pleasing on a nice stand. Any ideas questions comments or concerns please ask.

Does anyone know how I can get (or make) one of the regulator / valve things that screws on to a disposable oxygen tank? I would use the regulator from a propane torch but it has to have left hand threads. All the ones on Google shopping and Ebay cost like $40 and I realy don't want to pay that much, I'm thinking more like $10 or $15. I could use a Nitrous Oxide dispenser like the ones used for making whipped cream instead if anyone knows how to get or make one for the same price.

I was looking through the internet, and was linked to this page. There they used a freon can for the foundry shell, but I thought those small helium tanks would work too. I kinda knew that a dremel wouldn't cut through it, but it is just what I put on there. I used Inkscape and GIMP to make it.Also, does anyone know a good source for fire clay? I've heard that masonry supply stores are a good bet. Another thing - does anyone know a good page on a cheap, simple, charcoal foundry? I made a .gif animation describing my ideas, below. In the animation, I meant to put the part about cutting the hole for the blower in the beginning, too (after I cut the top off).

Ok, so I'm going to try to make this. However I want to make it so I can detach the big pvc reservoir and put on a new one for more than one shot. However, this is probably going to lower the psi when the air moves into the smaller reservoir. One more question: my plan is to make the air tank just screw onto the gun. Will this still be airtight? Do I need a quick release valve instead of threaded pvc? My plan is to make the larger reservoir but put a ball valve on the end where it connects to the rest of the gun. This is so I can screw it on and turn the valve.
Question by General Eggs
There was a similar post to this one a couple of years back, the difference being that both my tanks are filled from separate branches of the same supply using a ball valve in each tank to stop them filling. I then have an outlet from both tanks connected together that then goes off to a pump. One tank is 5000 litres and the other is 3000 litres, currently the larger of the two is redundant and its outlet valve is off, but come the summer i will need to introduce the second tank. I am located in southern Spain and in the summer they turn off the water supply to save water hence the tanks. My question is as the tanks are of a different size, if i were to fit the smaller tanks outlet with a non return valve so that the larger tank can not fill the smaller one via the outlet pipe, would this work i.e. would the joint outlet pipe still feed the pump correctly or would it have more or less pressure. I appreciate that i could balance the two tanks, but i would much rather be able to use all the volume i can. Many thanks.

I need some advice. I have a great idea that would be amazing if it worked. I want a small scuba/air tank whatever you want to call it (like a scuba secondary tank or a paintball co2 tank) that i can use to mess around with in a pool. I dont want to be constantly breathing, just enough to take a deep breath, go underwater and hold it for a minute, release air from the tank-take a breath, hold it, take another breath from the tank, hold it, and so on. Just enough to get a few breaths and be under water to last me for 5 or 10 minutes. The only thing is i dont want to have to fill it at a dive shop or from a tank that has to be filled at a dive shop like scuba secondary tanks. i want to rig it to fit a bike pump (which probably will not have enough psi to get the amount of air i want) or my air compressor. So i would like advice and also would i need an air regulator since im not constantly breathing? what could i use as a regulator if i need one at all?

I am new to compressed air tanks. I need some details about them. (For an air car actually) 1. How to refill a 4500 psi air tank. 2. How do I know the pressure of air comming out . ( Most Important) Can anybody please provide me a schematic drawing on how do I connect the air tank, the pressure gauges (Gauge 1. which shows the pressure and amount of air in the tank and Gauge 2 which shows the pressure of air comming out) and the compressor with the copper tubes. I read on a site formula for power of an air engine is HP= PLAN / 33000 where P. Mean effective pressure in pounds per square inch. L. Stroke in feet. A. Piston area in square inches. N. Number of power strokes per minute. How do I get value of N for the formula. Thanks for any help.

I did some research and saw other instructables that showed how to possibly create a UV sterilization. I read that UV light in the 230 and 360 range can break down Chlorine and Chloramines. I was curious if someone could share how to create a UV de-chlorinating chamber (2-5 gallons) with the use of UV LEDs. For safety purposes I was thinking of a plastic 5 gal bin, where placing the top on the bin completes the circuit to expose the water to the UV light in a safe manner. how many would be needed? how long would water need to be exposed?

I have been browsing through all the fish tank instructables and I thought that they were rather rubbish to be honest.... I want an instructable to build a decent tank in a rectangle shape with the dimensions of Height: 12" Length: 20" Depth:14" (Dimensions do not have to be followed but appreciated if they are and dimensions do not include lid space) If there is also any specific thicknesses needed for the tank to hold the capicity of water this would greatly appreciated if stated. I would also like the person who choses this project to use links to websites for the materials/tools (preferably English GBP currency) Any links to what types of fish are work well together would also be a bonus. Thanks in advance to anyone who will write the instructrable for this.

Hello!Here’s my challenge! I need your help. Could you recommend a build for this project?I’m looking to build a solution so I can film myself dunking a basketball. I would like the shot to follow me as I approach the hoop from about 10-15 feet away. My idea is a tank with a mounted GoPro onto it, possibly on a tabletop tripod as well.My budget is $50-100. The tank would need to move simultaneously with me as I approach the hoop. I thought perhaps a line tracking sensor could work, I could lay a piece of contrast tape on the solid colored basketball court. Or if I can program a movement with proper timing. Whichever is easier.I chose a tank versus car so that it would reduce vibration and steadier shot. Also a tank is sturdier so in case the ball flies over and hits the tank and camera.I don’t have any programming or robotics experience, but I’m a quick learner. I’d rather not tinker too much, and just want to have a working solution so I can focus on dunking!thanks for your help!Bhere’s a possibly chassis: OTTFF Robot Tank Chassis Track Compatible with Arduino Tank Aluminum Alloy Chassis Raspberry DIY STEM - Speed of 20m / min Maximum Load 2kg https://www.amazon.com/dp/B07C2Q63XG/ref=cm_sw_r_...
