You open the Yellow Pages and call a plasterer.

it's been a very long time since i did anything like this but i expect you mean some kind of arm with multiple joints where each joint has a single axis of rotation adding one degree of freedom to the end effector.
it's actually pretty simple matrix multiplication, first draw out your arm as long straight and flat as possible, take this as your 0 axis, at each joint work out how the axis of rotation differs from the axis you are on and calculate the rotation matrix from that joint including the length of the last section as a translation. now your axis has moved of course so then on the next one do the same, old vs new axis what is the rotation.
so then once you done that i guess you can calculate where each of the joints are and calculate a vector between each pair, if you want to plot them then plot the vectors and boom you have drawn in.

now the fun part is inverse kinematics, recalculate the whole thing in reverse and you can calculate what each joint angle should be to achieve a certain space in xyz!

basically its a good few hours of fun with maybe the most enjoyable application of matrices there is.

But I do not know how to program it
I need the code

Do it yourself.

At least you posted a picture, that is already better than many dumb question threads out there. You need to figure out:

1. Dimensions of you shelf i.e. measurements or how big it is

2. Figure out a way to mount it, if it is plaster board wall, you use anchors, if it is concrete, you use anchors but a different kind, if it is paper, you need to make a stand because the wall is not strong enough.

3. Go to shop, buy wood, cut wood, screw or glue together, and put it on the wall.

>>1162446
>shelf
that's not very descriptive

is it supposed to hang on the wall or be a freestanding unit

people give away free stuff on craigslist daily

otherwise it would take basic hand tools and some wood to make one

>>1162446
stud wall? screw into studs. fuck anchors. they can work. if you have to ask they won't work for you.
brick wall? rawl plugs.

bed bugs thread are a usual customer here, the solution is always nuke the place with https://en.wikipedia.org/wiki/Diatomaceous_earth

>>1162250
A place with bedbugs is considered uninhabitable in some states. Look into renters laws and see if you are entitled to have your past rent refunded, and gtfo out of there obligation free

They are coming from a trashy/filthy area somewhere in the building.

I was living in my apt for maybe 2-3 months and found them. Went through paranoid hell for another 2 months until I saw the next door neighbor had left their place. When I looked in, trash and food scraps everywhere, just disgusting. I know there's more to it than just that, but once that apt was cleaned out and disinfected, my issue went away.

I did get DEarth and other solutions, but it really wasn't until that shitthole was cleaned, did my problem go away.

>10W
>water heater

HAHAHAHAHAHA no.

>>1162239
I was thinking of a nickel -chrome cable.

>>1162247
You don't seem to understand, so I will give it to you straight, 10W is very little power for heating water, and is a stupid idea.

Probably soldered, possibly brazed

How do you solder a piece of metal flat against another piece of metal though? Just follow around the edges? I don't really see solder around the edges.

Can't find any guides or videos of anyone soldering or brazing sheet metal together like this, but I guess I'll have to experiment with it.

>>1162080
Google "building a wargaming bridge" and I am sure you will get tons of guides. I would look into MDF lazering and wood glue. spray that shit and paint it

>when I finally finished and booted

¿What did he mean by this?

>>1162031
Sorry. After I finished re assembling the iPad I turned it on.

Not sure but maybe you just got a shit quality digitizer. I've replaced 3GS screens a bunch, like for myself and friends, and I had two different qualities I'd get based on price. One would be the quality you described. If you didn't get an entirely new digitizer too when you put in new glass, check your ribbon connections. Maybe that is your problem.

Return the stucco and by a $3 bag of cement.

Its been opened, its been sitting in the garage.
Fuck.
Yeah ill prob have to swing by Home Depot and get a bag.

Just tried doubling it up and you can still see the plastic grill through both layers (pic related)

Any suggestions for a better brand?

>>1161905
Remove the grill.

you ask for advice on a board full of practical people wot build shit. They spend a few posts asking wtf it is/does/made of/etc. - none of which you can answer, because Pic Related. Everyone gives up.
tldr - if you want something built? try providing info. No one GAF about stealing your idea, we heard it all before. The ideas the easy part.

>>1161869
I'm not asking for advice to build it since it's far beyond the practical limit for a 4chan-based help, I am merely asking what one would do in this situation, where they need a functioning prototype but can't build one without professional assistance.

>>1161876
You pay for professional assistance, duh.
Or learn the required skills, get the required tools and materials and make it yourself.

>>1161676
why not just solder on a 3.5mm hole into the headphone

if you dont know how to google you can try bing.com, and i dont know what the fuck you are doing if you can't find 3.5mm jacks

>>1161677
I forget to mention, I'm looking for a 4 pole connector. I can find some dubious 3 pole connectors with locks that might go together, but I can't find any TRRS ones.

/diy/ is not your personal google assistant

seriously it is on google, try harder

scrape it off with some elbow grease, kid

stop being so lazy, kid

Throw them away and buy new ones

I'm considering trying an industrial degreaser.

yeah you could put a rubber over it, a flexseal or something, but they don't have much range in changing diameters.
i'm guessing you not in the third world over the pond using mm, but plumbing over here is pretty fucked, pipes are called 32/40/50 but if you measure it its still all in inches really, it wasn't resized to actuall integer millimeter sizes so it gets confusing.

what the fuck kind of pipe is that in the wall lead or something? looks fucked lol.

my goto would be just cut off the pipe just past the fllare then use something like a mcalpine multifit over it and then you are into sane territory you can use a few reducers or whatever to get to what you need for the trap.

>>1161243
I'd measure at pic related and see if that diameter would fit the pipe you are trying to fit it in. Probably will.

In you nearest hardware store you can find an adapter to fit in between. There is on that will fit from your existing pipes, but I would just cut away the part that reduces the diameter. It's there so that you can connect it to different kinds of pipes.

As a side note pipes have been replaced with PP, they aren't PVC anymore. Doesn't affect anything except that PVC is easily gluable as PVC isn't. PVC is hard to get rid of safely unlike PP. PP for example burns to just CO2 and H20. PVC will emit toxic chlorine compounds when burned...

>it wasn't resized to actuall integer millimeter sizes so it gets confusing

Well it isn't actually that confusing. Pipes are 32/40/50 and that's that. I don't think I even have an accurate measuring device for imperial units. My 50m measuring tape doesn't count as accurate.

The last bastion of imperial units is pipe-fittings. I believe those are going towards metric so it might be possible to get rid of a double-unit system eventually. There might just be an annoying phase where fittings don't fit, and as the name implies, fittings SHOULD fit. But that is the world of pipes anyway, annoying world of multiple standards.

>those guidelines

Take it easy there, Michelangelo.

Good start. Practice more. Also, use the correct board: >>>/ic/

Next time, paste the youtube link into the comment box so that it will auto-embed. That way more people will realize you are actually making a video using your character artwork.

The best part is that it wasn't done in fucking Flash. Which is very refreshing today.
