Alright, I have this idea I want to build. I have a Raspberry Pi 2 (Pic related). For my project to work, I'd need it to do two things. 1. Measure electricity 2. Remotely control a servo. Could it do it? and if so, how do I do it? inb4; Stick a magnet on it

If you want to measure a voltage you need an ADC, and possibly a voltage divider. If you need to measure current you also need a shunt resistor. To control a servo you should use a servo HAT. Look up all the tutorials for the stuff I mentioned and you should be able to make it work.

Yes, it's more work than clicking a few things on each other.

Trying here because hopefully someone might know:

So my last two jobs have had me dealing with algas sdi propane vaporizers, both pic related and their much larger big brother versions. The inlet valve is controlled by a large metal ball that floats on the lpg. When levels get low, it presses down on a metal rod that opens the inlet valve, letting more lpg in, a lot like how the float valve in a toilet works.

The problem I've run into at both companies is that the ball will get stuck up in the top of the cylinder. There's no buildup to clean nor any deformities to the cylinder and as soon as what the vaporizer is fueling shuts down from low gas pressure, the ball falls back down.

What could cause this/how to fix it?

Vaporizing LPG causing temperature drop causing cylinder to shrink, trapping the ball?
Just a guess. I can't properly imagine how the system works.

check that the feed tanks are actually full of propane.

I'd love to help OP, I really would. Possibly split them in half, do a half lap joint in the middle? That would probably just look like crossed dicks though. Take a sharpie and write "Not actual size" on the... shaft?... no matter what, so at least you're not embarrassed, and call it a conversation starter?

Hey /diy/, I need a piece of furniture for all my vidya geams. I was thinking one of those cube organizers might be nice, but they're all either tiny 2- or 3- square cupboards that won't hold everything, or they're giant monsters that would probably pick my TV like 5 feet off the floor, assuming they can even support my oldass Trinitron behemoth at all.

So, my next idea was to try and build something myself. But then I remembered that I have no experience and only a few tools. I'd like to get into woodworking/metalworking, but I've never really had a good idea how to start. Surely a wooden box wouldn't be too hard... Right?

Is there a guide for this sort of thing, or maybe a blueprint? What does /diy/ think I should do?

Step 1: give up trying to have everything hooked up to the TV at once.
Step 2: put each system in its own box with the games and accessories if possible
Step 3: rig up some video inputs and a power outlet so you can easily hook up whatever you want to play

Hi /DIY/

What kind of things do you carry everyday? I'm trying to become a more handy person ( have the right tools around at the right times, etc. ) and am looking for a good fixed blade for DIY-based tasks. Obviously there is a tool for every job, including blade shape, is there a good all-around option?

Also, can anybody tell me what the tool in the middle of this blade is supposed to be? I know what the other tools are ( hex wrench, bicycle spoke wrench sizes 14/15, O2 key, bottle opener and both inches/mm ruler ( inches on other side ) but can't figure out what the one in the middle is.

Two cell phones, a wallet, a gun (Glock 19 at home, .38 derringer at work), a knife (Kershaw freefall at home, Milwaukee fastback utility knife at work) and a Klien 11-in1 whenever I'm actually working. My pockets stay pretty full but 90% of the shit gets done without a trip to the toolbox.

Get a face mask, one of those disposable coverall and you'll need a sander.
Slowly cut back the layers around the crack and see how far the damage goes in. Fibreglass gets 'rot' so to speak where the layers separate as the epoxy has degraded- if the layers around the crack are able to be pushed in then you know its got some serious delamination and that'll generally be out of your amateur scope to fix.

If its still solid, then its a case of fibreglass, epoxy, more glass, epoxy, sanding and then repainting.

There's a lot of wire there that needs to be dealt with. I sure hope those aren't voltage lines. In fact, the 'r' at the end is rather useless.

I am trying to fix a power outlet in my bedroom. i have replaced all of them with new receptacles and still don't have any power to only 1 of them. I don't know if it matters but the outlet used to have a space heater wired to it. I have made a picture to explain whats going on

The outlet does not work still. If you're talking about the space heater that used to be there, the space heater worked. i don't know why it was removed
>>
>>986983
So the outlet worked until you plugged in a space heater and now it doesn't? Have you checked all the breakers in the main panel to see if any are tripped? There is no guarantee that all the outlets in your room are on the same circuit.

Vibration deadening materials? I'm trying to make a mount for my motorcycle, to mount my cellphone in the center above my headlight, so I can run my GPS. problem is, my bike has lots of vibration going on. and it slowly moves the mount around and such, and causes the phone to bounce in the mount making a noise.

Anyone have a good idea on how to retard the vibrations going through the phone mount? I also need some for the gastank. as the little rubber boot thats on there now, ain't doing shit, and when the tank gets like 1/4 empty, i get some really annoying harmonic vibrations goin on.

It is. And if it isn't, you can always make it sturdier.

Also, vibration isolation and "sturdiness" in the form of rigidness are fundamentally-conflicting goals. You DO realize this, right?

If I wanted to squirt a liquid though a vent into a locker, what kind of bottle would I need? I'm thinking something with a hose that could go through the vent?
6 posts and 1 images submitted.
>>
Like they said over in /adv/ - you need a 'grow the fuck up' bottle.
>>
So much to ask before I even attempt to answer.
What is the relative position of the locker to the vent, the type of locker is it, the type of liquid, the type of vent, whether you want the liquid to remain inside the locker or flow outside, whether there's something inside the vent, is the vent covered with something, how much liquid are you squirting and what effect do you expect the squirting to cause, the viscosity of the liquid, why a bottle, whether you have access to any kind of pump or whether you have to build your own pumping system, what's your budget, whether you really expected Tiffany to fuck you instead of Chad (I mean you're pretty fucking creepy, dude, and kind of retarded).
Give me facts, OP. I can't just answer your stupid autistic questions like that.
>>
Personally I preferred the hard boiled egg stuffed through the vent on friday before a weeks vacation.
