Is there any purpose to blank key caps?

Aside from acting smug and elitist when someone not very familiar with computers tries to use it, of course.

Is there any purpose to coloring stuff outside of color codes?

Faster learning how to blind-type.
Not OP btw.

to not have the tentacles drag on the ground I would probably need some air escaping, and to have air escaping I'd need to be carrying a battery and an air pump

But seriously, how big are we talking here? There are a handful of electric-blower inflatable costumes out there already. Here's an example of a blower that runs on AAs: http://www.yardinflatables.com/Replacement-Fan-for-Inflatable-Costume_p_2178.html
And the sort of costumes it goes with: http://www.gemmy.com/Airblown_Inflatables_Costumes_s/1848.htm

I'm willing to invest in a good pump since I've been looking at making a furnace, though I don't know how long that would last if I used the biggest battery practical to carry (A car battery for example if that can be somehow used for a pump).

Size of the costume?
As big as is reasonable, it's a fairly large character. Definitely bigger than any of the costumes in that link.

>I'm willing to invest in a good pump since I've been looking at making a furnace
I'm not sure what sort of pumping demands a furnace requires, but these inflatables operate at very low pressure and high volumetric flow rates. May or may not be compatible with your furnace.
>I don't know how long that would last if I used the biggest battery practical to carry (A car battery for example if that can be somehow used for a pump).
Alright, well let's see:
http://www.yardinflatables.com/Gemmy-Replacement-15a-Fan-With-12v15a-Adapter_p_1867.html
At 12v and 1.5a, you could run it off a 15 AH lead acid battery for 10 hours straight; such a battery would weigh about 13 pounds. Alternatively, an equivalent capacity lithium pack would weigh about 5 pounds.

Now, the inflatables this pump is designed to work with don't have external air jets like you're describing (that is what you're describing, correct?). Implementing jets would be a pretty significant risk, since you can't really know how well it'll work until you try it, and once you do try it, patching the jets up again if they don't work will only make the arms heavier and more saggy. If you have a ton of time, I MIGHT consider trying it; otherwise I'd just do my best to build the costume without them and maybe use fine thread or something to suspend the arms (or just pump them up enough and keep them light enough to stand on their own).

Enjoy your net loss unless you have retard high power costs.

Slap some solar panels on that bitch, "net loss" my ass

For all practically picking sets are obsolete, better off drilling, pin snapping or punching out the lock.

Lockpicking is not very difficult. There are Tons of Videos on YouTube

If it can lift a foot then it should at least hover

Sadly it doesn't hover it just drops after getting that high

>>989859
Have you tried over volting the motors?

How do you become a STEM coach without knowing that a generator is just a motor?

Oh boy, starting from scratch here. The hand crank (your "generator") is synchronized to the rest of the system. When current flows from the battery to spin the motor, it's also pushing back and causing the generator to act as a motor itself, because at the end of the day the only difference between motor and generator is the intended purpose, the construction is really the same. Assuming the hand crank is commutated (DC and not AC) You should be able to add some diodes to the circuit to keep current from flowing back to the hand crank when it's not being used. Without a ton more detail about the components you have, I cant tell you if that will work or if another solution would fix it.

Hope this helps

Bump,

Alright well I checked my other toilet and the float is stuck on so I think I found the culprit

I feel like glue is the bad choice but is there waterproof glue or something?

>>989610
Replace the seal. It will be cheaper than a tube of glue.

wat? zoom out to give a proper view

the "float" should obviously, float...when it's flushed, the lever pulls the chain, which lifts the flapper, when water lowers it triggers the fill valve to fill the tank, the float then goes up and closes the fill valve, the flapper sits back down and stops water from leaving the tank

if the fill assembly is broken, just replace the whole thing, a kit is <$20

Make friends with hunters, farmers, and butchers.

1.Go to the humane society.
2.Adopt animal with bones of choice
3.Drop in pale of acid
4 Repeat steps 1-3

>>989412
That'd work to an extent but the possible arrest, small variety of skulls and the price of a powerful enough acid make that plan less than economical or desirable.

Afaik Mechinical Engineers are quite valued in Hydrocentrals.

Sr ME student here, I don't know these would actually help as far as making the course work easier, but you will gain context of the ME application. ME is all theoretical calculations. You don't learn how to actually put your ideas into practice, just learn about the theory.

First 2 years is learning Math, Chemistry, Math, Physics, and more Math. Seriously you end up taking a couple math classes whose prerequisite is calc 3.

The rest of the courses are physics classes where you specialize in static mechanical loading conditions, dynamic loading conditions, thermal states, heat transfer, fluid flow, feedback loops (controls).
All of these are individual classes and you take the theory to the max
So now we know what the classes are about, what is the course work like? It's all about getting constraints and loading conditions and then applying the correct formulas and assumptions (this is where 99% of the work is) then crunching numbers, first by hand, then later with programs such as MATLAB, and ANSYS. You then circle the answer and turn it in to the professor. You then hope and prey you selected the correct conditions and formulas and that you didn't make a mistake with your triple enclosed tensor integral.

At the end of your coursework you will take a few classes that have a project in which you need to optimize a design this is where you analyze the problem (this takes no joke like 3 hours assuming you know exactly what you are doing and just are calculating stuff as fast as you can) now you start the optimization, you compare your results with your constraints and if the design fails you make one change and redo the math, then check again, then keep repeating this untill you get a passing design.
You should finally take a design course or 2 where you take the entire semester to design. Something from the ground up and if this thing has 20 parts on it, then you must iterate the optimization problem for each part.

There's a reason why Engineers get paid well

>>989432
With all this being said, I would pick manufacturing. If you know what a drill press is then there isn't much knowledge to gain from machining. Manufacturing will give you more insight into how materials behave as a result will give you something tangible to help imagine whats happening so you pick your boundary conditions/assumptions correctly. This is what engineers struggle with most, picking proper assumptions (these are also the engineers people complain about that don't have any real world experience and end up making questionable decisions)

I guess you could reposition it back together and throw on 2 or 3 steel plates that hold it together. Fasten them with screws or nuts and bolts plus loctite. It would likely be use able. But you're not gonna get it to be exactly what it was before.

you need a better monitor, or more of them

the fact that the start menu is big is irrelevant. when you maximize an app, it's virtually the same size on any Operating System. you can gain maybe 40 pixels in height if you auto-hide the taskbar.

if you set the resolution above the monitor's native resolution. the monitor may refuse to display anything, or it may compress the image. if it's the latter, it'll look pretty shit, so a new monitor is the best idea.

No you don't, otherwise you wouldn't be asking such bollocks, cheapo.

I was thinking a self resetting breaker and a 5w 20ohm bypass resistor. then just turn the lights on to discharge the capacitor with the battery disconnected. then it will recharge with the bypass resistor until it can close the breaker.

>>988724
Just wind a 2-3 Ohm resistor from some suitable wire

>>988630
Replace it and find out. We don't have a diagram to know that.

>>988635

>needing a diagram
the black cap is clearly burned out.

That cap doesn't look good.

You've got most of a Farad of 300v there. Discharging this stuff might be a good idea.

>>988418
Do you have basic wiring skills? Then not a problem. Your biggest task is going to be getting a 240V, 30A circuit from your panel to the rack location.

Check with city/county to see if you'll need a permit.

>>988457
Well I have the breaker I just need to install it and the one I want to get is a 300 amp seeing as I need 8 of these 30 amp plugs.

>>988484

just ask the maintenance guy of whatever fucking industrial factory you are in to help you out.
