I'm installing a projector, but there's one problem - it's a plasterboard/drywall type ceiling, and I'm not sure it's going to hold the weight (about 12 pounds or 5.5kg's). I've also got no idea how thick it is, but it seems pretty sturdy.
I was originally thinking of using 4-8 toggle bolts. The thing came with 2 75mm length screws which seem like they're supposed to go into a beam/joist rather than thin board. The mount plate is exactly 6 inches in diameter.
Can I mount it as is or will I fuck myself by ripping a hole in... Comment too long. Click here to view the full text.

There are definitely joists, in fact to get a perfect 4m throw distance it's about 20cm from the joist. I don't really want to mount it on the joist because 1) it would move the thing closer to the wall and therefore smaller image and 2) the plate wouldn't sit flush with the boards. I mean I could...

So the bathtub faucet has been leaking but my shower head is fine. Since Im covered under warranty, I had a plumber look at it. He said in order to fix the faucet I will have to have someone come and remove the whole wall of tile. What I expected to be a simple cartridge replacement turns out to be a whole different fiasco. Should I remove the tile myself or try to replace the cartridge myself instead? Pic related.
hello /diy/ i got a problem of creativity so i come to you. i need to make a poster with 80-100 cool images like memes and much more... I've started already and i got 40 files, but now i need you anon to get more!
I'm a welder, professionally, and I get stainless scrap from work for various projects at home. The problem is that I don't have a drill press suitable for 300-series stainless. I'd like to be able to make at least 1/2" holes without undue fuss or gnashing of teeth.
I know about what to look for (I use industrial presses at work), but I don't know exactly how that translates to a consumer benchtop machine. Pic related (http://www.grizzly.com/products/12-Speed-Heavy-Duty-Bench-Top-Drill-Press/G7943) looks pretty good, but how does it or similar models actually perform in the real world? Comments on brands, models, or nice features to look for would be appreciated.
Since this is for personal projects that I expect to make little if any money from, a more expensive machine will have to be justified by greater capability, not just greater productivity. That said, I can afford more than the Grizzly pictured if I have reason to.
Will answer welding-related questions in the meantime.
>>933033 If the scraps are small enough, and you can scrounge the materials for it, have you considered welding yourself up a punch press of sorts? If the stainless is thin enough you might even be able to use a sledge hammer to drive the punch. Like a coin blanking machine. Crude, questionable,, but cheap!
>>932987 >What are the equipment that he uses called? There's a metal lathe, then there's a turntable of some type. There is 40 videos in that playlist. I aint watching 40 videos for you, Nigerian. Link to the one video with the turntable if you want to know what it is.
>If I ever decide to start machining, would it be possible to buy one or two machines and use those to make any other machines I'd need? >Would it be possible to turn a profit creating metal machining equipment to cover the cost of the equipment itself? Generally, the precision you can get from a machine is always less than that it was built to.
Also to make normal metalworking machines, you need BIG iron castings (not easy to make at home) that have the way surfaces induction-hardened (to prevent them from wearing out and becoming inaccurate really really fast).
The Gingery books are fascinating, but it's a lot of work and (for most of us) considerable expense and the end result is a really crude, really shitty machine. Overall, even the little China machines would work way better than a carefully-built Gingery lathe or mill.
>>932950 When I was a kid I got interested in it, and it was one of the few interests of mine that my father encouraged, but as soon as my brain-damaged paranoid mother discovered I'd be communicating with complete strangers over the radio, she freaked out and thought I'd tell them where we lived, and someone would come and murder us all. Not making this shit up. No CB radio either, for the same reasons. Just as well there was no internet back then, either, or I would have been in the only house in my town without it,...

Hey electronics /diy/ers. I was just looking at some simple circuits, and theres just one thing I don't really understand about the operation of a basic astable or monostable 555 circuit.
This guy gives a good run-down here: http://pcbheaven.com/wikipages/555_Theory/
Scroll down to "Up and down in 4 steps!".
What I don't understand is this. When the capacitor is fully charged, and it is looking for the least resistive path to ground (see pic), why does it seem to discharge "backwards", rather than just discharge to the ground path directly below it?
Maybe there is something about capacitor theory that I'm missing?
So I have a coin that has great sentimental value to me, I want to carry it daily. However, sticking it in my pocket every morning is a good way to lose it in 2 days. It has a hole in the middle I could thread something through. I don't want to put it on a necklace like pic related though, because that looks autistic if you aren't a girl. What could I make to carry it with no chance of losing it?
>>932820 Depends on what you mean by "get into robotics"
If you mean as a hobby programming little toy arms they probably sell some you can program in python or use some sort of interpreter.
If you mean as a robotics programmer for industrial robots, read this article (http://robohub.org/the-future-of-robot-off-line-programming/) and then decide if you think you can gain the skills required. And it will probably be too expensive for you to do as a hobby.

You MIGHT find 3-5 gallon glass jugs at an antique or home decor store, apparently some get sold as vases. But realistically the only other option besides going through a homebrew store is using a plastic water bottle. Try finding a local homebrew supply or craigslist if you don't wanna pay shipping.
You're probably better off buying clothes that almost fit & going to a tailor to alter it. If you really want to DIY, you can learn to alter clothes yourself. Making clothes is pretty damn hard though. Don't do it unless you want something unique that can't be bought.
