I'm trying to come up with a simple and relatively economical way to filter water from a river. This water will be collected in a water container and be used to shower with (not to drink) even though the water is relatively clean as far as rivers go I'd rather filter, and sterilize it first to be on the safe side.
many of the existing water filtration solutions are either for:
1) small scale wilderness/survival purposes (katadyn,sawyer,lifestraw etc) 2) large scale installations for drinking in african villages 3) home point of use drinking (e.g berkey) 4) large scale industry use
So none of those are really suitable for collecting and filtering a large amount of water. Either they're too small with a slow flow rate, or they're gigantic installations
After a bit of thinking, I figured out the most economical non chemical solution is to buy standard 10" filter kits and just repurchase when they become clogged. The workflow will be like this
1) pump water directly from a hose through sediment prefilter, 2) then through a finer filter (0.5 micron) 3) then through a UV filter, into a holding container
>>1000490 A river? How the hell are you getting away with that? most rivers are highly protected by the state. Either way I would not use water from it. In my area at least they are pretty much toxic and polluted. The whole house filters you show are a good start. Creek water or rain water would be better. A sand bar or some light, easily replaced prefilter should be first. UV is a waste of power and money. Just get a 2 micron if you need to drink or eat with it.
A few months ago I came here looking for a chain that wasn't just loose links, but could both coil up and be rigid and straight when arranged correctly. Someone mentioned "barrel chain", but I came to the conclusion that chain of any type would be too heavy. So I'm back with a new method, using spring steel similar to a tape measure.
A tape measure will extend and stay straight for about...what 9-10 feet when used correctly? I want to make a device that could be applied as well as improve the design of a tape measure to make it extend 30 ft and stay... Comment too long. Click here to view the full text.
>>1000231 yes i thought of that, but it needs to function from most angles. A triangular design would crimp sideways. The best design I can think of at the moment is something resembling a chinese yo yo with a coiling steel spring.
Hurricane Season is here, I'm preparing my game room as the family shelter after we return from evacuation. I want to use quiet, fuel efficient inverters because last major hurricane it was nearly impossible to find gas, I need to shitpost on 4chan using my comfy desktop computer, and thieves won't easily here them humming away. >Have a Wen 52600i 2000 watt inverter generator aka Yamaha clone for camping / power tools >thinking of buying 2 more because they are cheap, simple, and work well.

>>999476 I'm pretty sure it is 120 with both legs powered from same hot in phase, so pic related would kill 240 devices, but if distribution downstream downstream only goes to 120 stuff, should be a non issue, just has half power.
I need to sharpen a lot of commercial mower blades. I currently use a classic two wheel bench grinder light duty. I want to make a jig to get an even, quick and constant result. But the god darn thing has no tool rest and it doesn't really make sense to adapt something. I'm not sure what kind of steel, other than "1/4" (6.4 mm) thick heat-treated steel" that sells for about $50 USD for a set of three.
Should I buy a beefy heavy duty bench grinder or a decent belt sander?
This is baby shit mang. I made these jig plans in my head in like 30 seconds, so let me know if there need to be changes.
You need to pieces of steel, one angle, one flat.
The circle thing is your grinder. You're gonna want to weld your angle piece to the flat one at the angle you want it cut at. Then use a clamp or vice grips to secure the blade to the jig, with the end you're sharpening hanging off the side so you wont be grinding on your jig. Hows that sound?
Hi /diy/ I'm hoping to paint up some weights I got off craigslist they're a little beat up and have some rust on them. Do I need to do anything special to prep them beyond cleaning them off or do those rust paints really work and I can just paint over it?
Why is it so hard to make one?! First, I try using my raspberry pi which doesn't work (cause its a B+,) than I tried making one through the good ol' transistor radio schematic (with the oscillator chip and whatnot.) I don't have the parts, so I can just drive to a radioshack, right? But they are closing all of their stores! Ugh. Are there any quick alternatives I can try for making an fm radio station (online, through my raspberry pi B+, etc?) And if /diy/ can help me, I'll give you all the frequency so if you're in my area you can listen to some tunes!... Comment too long. Click here to view the full text.
>>997028 Why, how are you going to use it ? Like streaming music thru it and everyone that actually listens to 420 mhz is going to listen to your music as long as they are 20 yards away in clear sight from you ?
Its pointless, give up. Join the Ham radio master race
I need to make a few joints like this somehow, most likely out of plastic, for a posable model I am making. I don't have any idea where to even begin making something like this. Any advice? I hope those measurements are clear enough to follow.
Yeah man, I don't have one and I don't know anyone that has one. Also I live in the middle of bumfuck nowhere. Is there like a website or something where I could upload models to have printed and shipped for a reasonable price?
Hey /diy/ I'm looking for something that you can basically paint onto a leather sole to protect it from wear. I was thinking bitumen may work but I'm not sure if it would adhere sufficiently and withstand the abuse soles have to. Also it may melt on hot surfaces.

I was thinking bitumen may work but I'm not sure if it would adhere sufficiently and withstand the abuse soles have to. Also it may melt on hot surfaces. --also it would leave ugly black marks on any floors, when you dragged your feet even a tiny bit. Which you probably do, because most people do--you just never saw direct evidence of it before.
It would help to explain... Comment too long. Click here to view the full text.
>>999764 >Wires are rated for voltage >They dont give a shit if its AC or DC they just conduct That's what I always thought, but seeing the description of "DC Power Cable" and all of those mouth breathers on Amazon calling it a DC cable made me question it.
Hi! I want to water my plants on my balcony while i'm not there. I bought an electrovalve which works with 12v, 8W, and I want to supply it, or not, with a laptop. I thought the serial port would have do that, but I can't get any current from it, according to my voltmeter. Is it possible, do you have any ideas?
You're right I don't know serial ports much.. I just want to get some 12v from my laptop. I thought I would have used a linux command like rtcwake, which wakes the computer and that way the 12v from anywhere would be active. And then, 1h later the computer would go back to sleep for 23h.. something like that. I know there is some 12v on the cd drive, but it would be easier to get it from an external port
I took of the CDI box from my motorcycle as I suspect it's faulty and I'm replacing it. Looked like this from the bottom. What the hell is that shit? I digged a bit into the bottom which is soft rubber and it's filled with that stuff.
looks like gravel wtf, did some one dropped that thing on the ground during potting (re-potting after repair?!? its not serviceable)? i doubt, even high speed, projected gravel would embed itself so neatly in that really weird indeed
>>999464 Is the stuff that looks like gravel actually gravel? Or is it just more of the rubbery stuff?
I would guess it's just more of the potting compound and it just didn't mix right or maybe it was the bottom of the barrel.
The rubbery junk is potting compound. You pour it on electronics to protect them from vibration and moisture. It also makes them totally not servicable. There's nothing to fix because it's such a pain in the ass to remove.
