Hey guys, I've got a weird question and don't know where to ask it...
I am thinking about greenhouses, and I've decided the gothic arch style is best. It provides a ton of headroom though, so you could add a second level. But then some plants might get smothered. Is there some kind of "one way coating" that would bounce more sunlight across? That way it lets light it and reflects it a little.
Then I started thinking about underground greenhouses.... could you use a series of magnifying glasses to concentrate sunlight down a series of mirrors... Comment too long. Click here to view the full text.
I have a question about electroplating and would like to know what you guys think. So i have a bracelet which is made out of leather strings and a symbol as the main part made out of some metal. I want to electroplate this metal, i was thinking to plate it with copper first and then plate it with a thick layer of silver. My question is what kind of metal the main part of it might be, it is not magnetic at all and does not rust, i thought it might be stainless steel or titanium since those two are relatively skin-friendly and are used for such purposes. Is it still... Comment too long. Click here to view the full text.
>>942627 I don't have it with me right now but i will make sure to post a picture of it tommorow.
I already let a jewelry store cast the whole thing as silver before and gifted it to my wife as a present, the original thing was the first thing she ever gave to me so i thought maybe i can atleast make it look nicer so it doesn't look like the usual hipster infinity bracelet.
Why silver? I don't really know actually, it's cheap to get and i like how it looks.
My Sony Xperia M4 Aua got into the pool 3 days ago (Irony) I put it into rice Can i fill a bowl with isopropyl alcohol and put it in there? I mean, will it work? Can't disassrmbe it(integrated battery) Anyone knows how to???
The rice thing is a myth. The only thing to do is to dry it out, which is best done by opening it up so air can get inside. Depending on the device, you can then clean any corroded pathways with electronics cleaner.
I'm not sure if this would work for phones in general, they may be too delicate for post-water-damage cleaning to work, but it certainly won't work if you can't disassemble it.
I previously had no experience at all with wiring, electronics, breadboards, ect., so I've been learning slowly through experimentation and online stuff
So pretty much, I bought a breadboard kit and some 433hz Radio transmitter/receiver pairs. My goal was to use the little transmitters to send a simple signal when they were powered. The signal from each transmitter lights an LED connected to each receiver.
I've learned that this isn't that simple. Do I need one or two Arduinos? Can I just do some simple analog signals or something? It only requires... Comment too long. Click here to view the full text.
what the hell is that little metal thing called. I've tried anything from pipe screen to mesh bowl and I can't find anything anywhere? also not sure where to post this, if I'm in the wrong place would you kindly redirect me?
Hello, /diy/, I have a question for you. Recently I've been reading about tendon-driven manipulators, and I want to build one for fun and learning. I think I got the idea for the arm and ropes itself, my question is about motors. What should I use? Servos, stepper motors, dc motors? Or maybe long-ass linear actuators? My goal would be to create something strong enough that it could beat an average human in arm wrestling. Assuming that whole thing does not break, how can I achieve required torque/force as cheaply as possible? I'm a student living in Poland, so delivery... Comment too long.

The strongest thing you could realistically get is hydraulic servos. Naturally, these are complex and expensive. But ANYTHING you can use to pull the tendons will work. Cheapest practical option is probably going to be a geared stepper motor.
That being said, unless you kind of cheat a little (and use different kinematics than the human arm) or greatly limit the capabilities of your machine such that all it can really do is arm wrestle, you are never going to beat a human in a strength contest on a budget....

>>942520 Thanks for the UHMW tip, definitely going to try that. Hydraulics are probably out of my reach, will look into stepper motors. As I was poking around the Internet some more I found this video
Guy uses one drill motor set on high torque/low rpm to lift himself off the ground on a rope. And poking some more I found that quite a lot of people are selling old drills cheaply. Usually something about them is broken, but I guess I could try to repair it and salvage the motors? Of course... Comment too long. Click here to view the full text.
Sorry for the fairly basic question, but Google is falling short. Picture is the boiler in the place I'm staying for the next two weeks. Typically I arrived and there's no water pressure, but also no visible filling loop or even valves to connect it to. Google tells me that this model (Baxi Platinum, eurocentric model by the looks of it) often uses a rigid filling loop but from a few videos I've seen in some cases it also just connects to a valve somewhere in the apartment.
Unfortunately I've looked under sinks and in closets all over the apartment... Comment too long. Click here to view the full text.
I wanna start printing designs on t shirts, whether as a serious thing or just for myself and buddies, time will tell. I've been looking at a lot of techniques, screen printing seems to be the most professional, but I also these transfer paper thingies, and I've seen textile factories use these. What would be the cheapest way to go about this, anything I should know that's important around this topic? And does transfer paper do the job well or does it fade shortly after?
The ink and emulsion is where it gets expensive. The screens are around 30 dollars a piece. If you want to get into screen printing I recommend a small two or four station machine before spending hundreds on a big elaborate machine.
I've decided I'm tired of using chinkshit precision screwdrivers to tear apart chinkshit electronics and I want to spend some money on a gud set. The rest of the internet seems to think Wiha is the best but what does /diy/ use? Do you use multi-bits or traditional?
>>942339 I only use multibits for the random shit (read as torx). Wihas are good, but overkill if you're not working in high voltage environments. This is one of those deals where most all mid level does just as good as high level as long as you don't need the additional safety features of high level stuff...
