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

Back in the 70s and 80s before LEDs became so good bike lights that used a generator spun by the wheel were commonplace. I'm sure you could still find one.
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.
>>991597
>could I use this camera as a camera?
You're better off going to something like DX.com and getting an already working pen camera and working from there.
>>991597
>I assume I'd have to compile a driver for it (something I barely know what means),
You also have to design and build a board so you can have it communicate with the computer.
>>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.

I don't know if you're being a cunt or not, but I don't like your post.
Instead of building a yacht to sail across the world...
What about an airship?
Nothing ridiculously luxurious, basically a flying home with all the accoutrements a long term sailboat would have... like a houseboat airship.
Check out this website. It's the most inspiring one I've seen concerning the topic of airships.

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...

>It regenerates its own hydrogen gas out of rain and wind power
Amazing. You could cover the entire balloon with solar roadways, too!
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...

Is making ball-jointed dolls a terribly difficult hobby to get into?
I wanted to make my own doll but was thinking of embedding steel bearings and neodymium magnets into the joints instead of all that string shit.

Any tutorials you can share?
This makes me uncomfortable
How do all yall metal workers/welders get your metal? I've been getting my flat bars from home depot but I figure there's a better place.
>>990650
Grainger has some stuff and they usually have a local store just about anywhere in the country (US).
Google metal supply for online resources like http://www.speedymetals.com/
>>990650
Around where I live there are a couple of places I go, a steel fabricator and a steel recycling place. They are both local so there's not much point in going into details.
I can go there and get 20 ft of steel (in pretty much any possible shape and thickness) for less than the cost of getting 3 ft at Lowe's or Home depot.
Look for steel distributors in your area in the phone book or online.
Please, please stop buying from hardware stores, you are literally robbing yourself, throwing money down the drain.
Stop buying material from a hardware store. Find a local metal supplier. The selection will be much better and with lower prices.
I live in Ontario and I use Golden triangle speciality metals, production metals, and metal supermarkets.

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
Smoke em with your asshole.
>>990505
>1 pack
>45 minutes
What the fuck is wrong with you?
As a side note, if you lived in Australia, you would be homeless by now.
>>990505
re-inhale the smoke you exhale, you can do it easily with the smoke tank from struttergear

I know one of you genius bastards are trying it.
How's your progress? Post your plans! Help us degenerates understand...
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,

Just use bigger engines or bigger propellers then. Think inside the box, man.

Just use a helicopter.
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...

That's some quality tradesmanship work there. Definitely need to cover that up with some foam man.

I figured as much, is there a particular kind I should buy? I'm no handyman but I can recognize crap work and know enough that condensation is not a good thing
Hey diy I know it's nothing special but I made my frist cutting board today and it turned out okay. What have you made recently.
>>977560
Looks nice. Congrats. The first projects are always the hardest
>>977562
Thanks
>>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...

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?
you should always use eye and vision protection
>>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.

dude, you're overthinking this
last year i built two tables and i used nothing but a cordless drill, a bowsaw, a handsaw and a sander(but you could just use sandpaper)
you can get the wood pretty much the size you want it from your local store, they'll normally cut it for you
ITT: We figure out a way to create a solar panel from scratch with, hopefully, enough power to start a small RC chopper.
I dont even know how to start, any takers?
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
>>992955
Are you that fool who wanted to make his own fucking cement a while back? Have you even looked at how solar cells are made?
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!
5 gallons of pressure treated wood
Depends. 4 Americans or 4 Ethiopians?
>>992941
5 gallons of pressure treated imitation crab meat
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
How much are you bending it by? Are you trying to crease it or form a radius curve?
>>992836
I'm not sure what you mean - I'm not a native speaker, I don't understand what you're suggesting.. but maybe this diagram helps more?
what's the difference between creasing and radius curve?
>>992836
also this might help too
Recommendations for a mini set of taps?
There are some on amazon, though the quality seems to be pretty low. Not looking to do anything crazy, just fix the holes in some knife scales. Cheap is the word...
>>992583
Save yourself a headache and get some 3n1 oil instead of the wd40.
>>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.
>>992583
small taps are not where u want to cheap out on OP, you will break them off inside holes and totally wreck whatever youre working on
So this kid in my class is making a quadrupedal robot. With 4 servos. Without knees.
I'm trying to think if there's any possible way to get this thing walking?
Spare using momentum to throw itself, I just don't see it going well.
Thoughts? Also robot dump general.
Another angle
>I have no knees and I must kick my creator in the bollocks
Designs like this seem like a much better use of four servos
