Got a bit of a problem.
I was mowing the backyard today and clipped my water tank. I don't know shit about them and figured i'd see if anybody here knows about water tanks, seeing as i don't know the make, model, part or anything about them.
About 4/5ths of the way down my tank there's a piece that fits into the tank and is attached by a very thin piece of wire that runs down into the ground through some PVC piping. I've torn that piece out and now my backyard looks like a swimming pool.
I can't get it back in while the waters racing so i figure i'll let it drain then get it back in once its empty no worries. All i have to do is push one half of a rubber seal inside the tank and then it should fill normally.
That's the plan anyway.
Any tips, information, part names and knowledge or experience would be greatly appreciated.
Otherwise you can just laugh at the dickhead who pulled the plug on his water tank.

Hey, /diy/. I am planning to build a street-only gokart pretty soon. There is an instructables online I'm basing mine on, however the creator uses two brushless motors as the drive motors. I'm afraid that they may not be powerful enough, so I was wondering what the differences are between using two Turnigy 5065-256Kv Brushless Outrunners or two CIM motors. I'm on a FIRST team, and we used six CIM motors to power our robot, which weighs less than I do. So two CIM motors may not have enough power either.

hey guys & gals,
i'm just an electronic newbie and want to make
a "bench" power supply on the cheap (tired of making voltage dividers every time i have to work w/ something i don't have the adequate supply for).
I made this schema (http://imgur.com/wc88kX5) based on this idea (http://hackaday.com/2012/06/26/bench-supply-built-in-a-power-strip/).
that'd output 3.3V,5V,10V,12V,15V,24V,1 variable(2.5-15V) @500mA (exept the 24v which come strait ou the original suplly, can pup up 1.2A) for something around 15€ (+pcb+original supply which is flea market bought ).
The original build had switches but these ones would pimp the price tag a bit too much (more expensive than the vregs at my usual supplier (mouser)...)
so, got some questions:
- do you see any blatant error in the schema ?
- would you choose other vregs ? why ?
- could the switches expand that much life expectancy of the vregs ?
- have ideas to enhance it "on the cheap" ?
thanks for advice
Ammo Can Emergency Stash

Lately I've been using an Ammo Can for emergency storage. I've got my passport, a copy of my birth certificate, a couple grand in saving bonds, my important photos and notebooks (in sealed plastic bags).
The container is watertight, seems pretty airtight when sealed, and is obviously sturdy, and easy to transport. Any issues with this? Any flaws I might have overlooked or suggestions?
