So I'm trying to figure out how I can make something you can attach to a bike that charges a battery and in turn a phone. To even get started, what motor could I mount to the bike that would allow it to charge a battery at something like 5v and 2a, while buying spun by the wheel. I get the voltage regulator part but I can't figure out what motor I should use or how I'm even going to mount the fucker Thanks for your time
hello, /diy/, I see there's plenty of components in the market. If I wanted, could I theoretically use this as a camera? It's a 4k camera module for little above £4. I assume I'd have to compile a driver for it (something I barely know what means), but what else? Figure I could use this as a webcam, pocket camera or CCTV.
>>991635 there's no easy mode then. maybe I could put it on pic related and buff the raspberry pi camera :^) though the one in picture has a controller (?) attached to it, something the Galaxy S6 camera module doesn't seem to have.
>>991631 I don't know if you're being a cunt or not, but I don't like your post.
I'm posting pictures from that site. He's got videos of tests of the development of the safest gas bags imaginable. Pure hydrogen isn't flammable at all when it's contained, oxygen makes it flammable. But what about lift gas alternatives? Hot air, helium, etc? Could you have a combination lift gas, like hot hydrogen or hot helium? Both those gasses will expand when heated and provide more lift for the same space, right?
What about combining the benefits of sailboats and airplanes with airships? Could an airship have sails? Because you could have sails... Comment too long. Click here to view the full text.
As for benefiting from the lessons learned from airplanes, I imagine a lifting body design would be beneficial. It could have wings and a tail for even greater control and lift, too. The wings wouldn't need to be large at all, lifting body designs allow for much smaller wings.
There are so many things we've learned about flight and it's kinda hard for a single person to imagine how you could combine all those features, so I'd like input.
I absolutely adore the design and theory of the ship in the pics I'm posting, by the way. It's... Comment too long. Click here to view the full text.
Hello there diy. I am having an extraordinarily bad day, and I have 1 pack of cigarettes to last me the next 45 minutes. How can I make a creation that will limit my smoking time from 30 seconds a cigarette to 2 mins a tubhacco cigarette? I am sorry to bother y'all mafakas, grow a pair, and fuck you thanks bro
It doesn't have enough power to be useful (he even says himself that he had to not include any control systems because it would be too heavy) and it's a dumb idea to begin with. Not useful in any way and pointless to make,
So recently my landlord at my apartment had to replace the outdoor unit for my AC due to it being old & no good.
The unit itself looks fine but I question the installation job.
For some odd reason when they replaced the outdoor unit, they didn't bother to replace the foam insulation for the refrigerant line. A good part of it is exposed and I had the idea to buy some to get it covered up assuming it's pretty simple to do, should I bother.?
Also as to why I just haven't asked the landlord, the repair guy is pretty unreliable and often... Comment too long. Click here to view the full text.
>>977560 nice work OP. looks quality, 10/10 would use that cutting board!
today i made a couple "dead kitten" wind muffs for my location/field recording mics. i've made larger ones last year for a pair of studio mics so i was familiar with the process and got a few things right this time that i didn't get last time. i already tested them out and they work fucking fantastic, and they sound good too.
the pelt of faux fur was $3, I used about half of it for the two mics and some thread and about... Comment too long. Click here to view the full text.
Hi /diy/, I want to start making things out of wood but I have no idea where to start. I've googled basic tools for beginners and read the woodgears.ca page for plebs and all that, but my problem is really putting this into real life. Should I buy a sawhorse or a work bench/table? Apparently I should make my own, but if I do, what the hell do I cut my wood on? And how do I know what wood to use (type, thickness, etc.)? I know I want to try making a table but I don't have plans for any of it; no measurements, no idea what kind of wood I'd want. Not sure if I should get a jigsaw or a circular saw or both. I have a couple questions regarding protection as well: Do I need any special respirators or masks if I'm just cutting stuff with a jigsaw or a circular saw? How loud are any of these motorized saws - should I get ear protection? I did woodworking for a few months in highschool so I have a bit of knowledge of how things work, but it was an established woodshop with everything I'd need already there.
>>993079 >I want to start making things out of wood why?
>Should I buy a sawhorse or a work bench/table? depends on your budget
>what the hell do I cut my wood on? anything solid
>And how do I know what wood to use (type, thickness, etc.)? depends on your budget
>Not sure if I should get a jigsaw or a circular saw or both. depends on your budget; circular saw
>How loud are any of these motorized saws - should I get ear protection? >I did woodworking for a few months in highschool >it was an established woodshop an "established woodshop" but they didn't have any motorized saws?
>>993083 >why? Because I want to make things. Specifically, I eventually want to build a large wooden terrarium as glass ones in pet stores only go up to a certain size. >rest of the post Assume budget isn't really an issue, I guess. >an established woodshop without motorized saws? We only got to use the bandsaw, so I've never seen them in use/had a chance to use the other saws. >always... Comment too long. Click here to view the full text.
Starting and flying are 2 very different things...
I'm not familiar enough with current solar tech, let alone trying to Jew it from scratch. But just looking at the designs for solar planes.... I'm not sure a solar powered helicopter is pheasable. This does have me curious though, I'll stick around and watch the shenanigans ensue.
No way in hell would you be able to do this. a solar plane might be kinda doable...maybe... with high quality cells No way are you going to be able to diy a panel that will have enough juice to power anything other than a calculator
hi , I want to do a floating dock with 5 gallon and I have some questions on how to make the dock. Which wood should I use ? I know I have to calculate the weight of people and dock. For a dock for 4 people , what weight can it has? Thanks!
I have 4mm thick walnut veneer that's about 310mm wide. All I have is a steam gun - can it be bent according to my plan? Making a computer case. I can set up jigs and shit but I've never bent veneer, just want to be sure if there's some limits or some rules of thumb like "you can't ever bend over x degrees if your veneer is y mm thick" or stuff
>>992583 Cheap taps and dies (like any generic ones, and even those name-brand sold at retail hardware stores) are generally really shitty quality. They break really easily, yet even with lube they require like TWICE the torque to drive them. Plus they don't usually say the size tolerances.
My advice: Go to a machinist supply website, and just order the specific sizes of taps and dies that you need. They cost more each but you can just get the ones you need, so the total cost is not high and you get much-better-quality taps and dies.
Dies can be made from HSS or carbon steel, but taps should *always* be HSS. The reason is that HSS is tougher and more-resistant to breaking, and this is more important with a tap than a die.
Taps and dies from machinist sites let you specify the "fit", which is the part clearance between the "screw" threads and the "hole" threads. I normally buy 2H taps and split dies. (the die fit of a split die is adjustable). REEEAALLYYY tiny taps & dies may not offer different fits at all.
You can use any oil for cleaning up threads or cutting threads in most metals, just use something. Even vegetable oil works. For hard steel or stainless steel, get proper tapping fluid.
Hand tap sets will have 3 taps each of the same thread size. I usually buy spiral-point taps, but they are plug taper and can be difficult to start in a hole without some method to guide them. I have a drill press and milling machine for that.
