Wanted intructable - "Convert an Aquarium Air Pump into a Vacuum Pump"

Hey all - Wanted intructable: "Convert an Aquarium Air Pump into a Vacuum Pump" I know this is pretty simple - probably... as well to add to that a mod... "Convert a Aquarium Air Pump into an Adjustable Vacuum Pump" I'm trying to build something else and would like to see how this is done - i have one shot at one Aquarium air pump and don't want to mess it up. Plus i'd like to know how to regulate the vacuum  - make it with adjustable vacuum pressure if possible - if i even really need to or at least regulate the vacuum pressure so it is not too much if it is after built. I'm sure i could do a google and find all the parts - thinik tank it out and build it... but if you know already how to do it - makes things a tad easier for me. The instrucable even easier to avoid mistakes. thanx - chase -

inflating and deflating a air bladder continuously?

I am interested in a project however what i need to do is to inflate and deflate a air bladder repeatedly on a continuous cycle (so inflation and the deflation). This making me think of a piston style pump hooked up to a motor which I can control through use of a variable resistor. Is there any piston style pump i can use or is there a alternative which would be better. (I do have a budget of around 70usd)

variable output dc water pump for a wind generator

I'm interested in figuring out how to direct the energy produced by a wind turbine into a water pump. My goal is to pump water from a river to the top of a hill into a pond. then slowly release it through a variable water turbine so that the pond serves as a battery. i've seen pumps that work with the power take off(PTO) of a tractor that could be retrofitted if i had the right dc motor. i need to figure out what motor might work and what type of contolling i would need. also would it be better to use several smaller units that engage one at a time as the power input increases to keep the pumps closer to thier ideal operating range? The (PTO)water pump i saw operates between 17-23 hp or 20kw or less, which is perfect because the turbine is 20kw. the other thing is what if the pump operation starts at 17hp(?) then most of the power would need to be directed somewhere when producing less. maybe a series of different sized pumps and a controller to determine which pump(s) to engage to get the most water pumped.

searching for a pump that can handle pudding

I dug through a few forums, trying to decide which this was best suited for. I settled on tech since its a physical computing project. I'm looking for a resource for a water pump that can handle something like pudding. the initial thought was use an air pump and a bag or maybe have the bag be squeezed closed but i need it to cycle through.  Like a water fountain of pudding! The pudding spurts out, then there is also an intake which is recycling the goop. Does anyone have a resource on pumps which could handle something so thick?  (and since its a small scale project, cheaply and small!)

Amps for 12 volt tire inflation pump

I'm trying to attach an AC adapter to a 12-volt tire inflation pump (the kind that plugs into your car's cigarette lighter), then convert it into a vacuum pump for degassing molds. I tried connecting the only 12 volt wall wart I have and it just barely got the motor moving. I'm guessing that the amperage of the adapter is too low. What sort of amps would this unit need to run correctly? Is it even possible to run this thing from a wall outlet?

water pump idea

I hypothesise that when is heat applied to a suitable sealed vessel, filled with water, and having a pipe into the base of the container below the water level, that when the water gets hot enough, it will exit the pipe under pressure. if anyone has any input or had experiance with this kind of a thing or knows of a device which works in the same or similar manner, i would like to hear from you.  i though it could be a way of moving water with no moving parts or access to electricity, motors etc. thank Kim.C.S.B

Air Compressor/Vacuum Pump

I have a theory: You have your supply of compressed air. You connect that by hose to one branch of a y-connector. The other branch is connected to a hose that goes into some sort of fluid that you want to move from one vessel to another. The trunk of the y is your exhaust (in theory). So now I give, say, 15 psi out of my air supply and that shoud drag my fluid out of its vessel through the y connector to the destination of my choosing. Would that work?

Hoping to convert a couple 12V DC sump pumps to run off 120V AC...Wondering if someone can give me some pointers? Answered

I found a unit that I think will work - a Tripplite PR20 20 amp AC --> DC power supply, which plugs into regular AC and converts to 13.8 volt DC, but I'm hoping somebody can tell me A) If it will, in fact work B) what will happen if it doesn't C) Can I get away with a lower amp version of the Tripplite unit? Do I need a higher amp version? D) Whether or not the power supply will draw continuously from the outlet even when the sump pump isn't running, thereby jacking up my electric bill to the point the project isn't worthwhile.  The pumps are from two different brands of battery back up sump systems;  Basement Watchdog, and Ace in the Hole, but seem to be of the same power demand and hp.  I would only be hooking one of them up at any given time to the PR20.  I also have a 12v dc float switch on which I would install an interrupter plug  to make this work (until it wore out, at which point I'd switch to an AC float switch with interrupter and plug the Tripplite into that...).   I know I'm making more trouble for myself than it's probably worth, but these pumps are brand new, and I could save a couple hundred bucks if I can make them work...Any help or advice you could offer would be great.  The Tripplite unit specs are available at Tripplite.com; just do a "model search" under PR20, or PR...There are a whole line of different models w/varying amp ratings...

I'm probably over thinking this and there's a simpler solution, but a refrigerator is already a well sealed, temperature controlled, shelf. If I could get a second hand or scratch and dent, could the condenser be put on the inside to make a "warm box" for winter?

New knex pump action idea

Ok, to start off, If you are wondering why I dont have a gun to demonstrate this concept, its because I just thought of this a few hours ago.So anyways, I have an idea for a pump action concept. This idea would work like thisthe rubberbands would be hooked onto the pump instead of the gun via Y connectors on the pump.when the pump pulls the ram back, the rubberbands do not expand or contractafter the ram goes behind the trigger, the pump is pushed forward, expanding the bands and giving the gun its powerthe pump hooks into a locking mechanismthe trigger is pulled, and either recoil or another mechanism hooked to the trigger unlocks the locking mechanism for the pumpThe advantage of this over other pump action guns would be that the pump would be easy to pull back, no matter how many rubberbands are on the pump.
