Hello folks.
My wife and I are interested in building a vardo / gypsy wagon (pic related), for use as either a camping trailer, guest house, or possibly even for long term living. There are a variety of build guides I've found, but I thought I would drop a line here to see if anyone has any experience or advice on building campers in general, and tiny campers in particular.
Anyone have any stories, resources, or advice on these things? I know it's probably a long shot -- but the internet is a strange place, so who knows.
i have found these work really well but dont forget to ask questions like
how experienced are you driving with a trailer
how much will this flex during moment
will this include any sort of pluming
and so on
Hey Anon, if you want to know more about building one of these before you get into it, try looking up tumbleweed tiny homes. They have people who travel around the US doing weekend seminars about the finer points of building your own tiny home.

its super easy to build one for cheap!
Hi folks!
I rarely come to this board, but figured you could help me.
I would like to set up a 5.1 sound system in the room of my new apartment and the owner gave the permission, but asked me to make it so I can fix it if I move out in the future.
What can I use which can hold hanging speakers and can be removed with the least damage to the wall?
How heavy are the speakers.
If you can hit a stud, a simple screw would be the easiest to fix. Otherwise you're basically stuck with anchors. The trick is to just tap them below the wall and spackle over them.
should be able to use these things and not worry about any screws.
>>948097
Those are nice. If you want your speakers to fall down and break.
Pic related. I don't need much, just room to sit and look out the windows. Maybe enough space for a bed so I could spend the night.
I live right on a lake, so supplying constant fresh air from an electric compressor running on grid power is no problem.
I'm just trying to figure out what to make it out of and the logistics of getting something heavy enough to hold down all that air into the water and sunk where I want it.
This one's made out of a water storage tank, one of the options I was looking at. If I could find someplace like a junkyard to get one for cheap that'd be ideal.

I don't think so. I'm scuba certified and have a great deal of diving experience, I have a solid grasp of the principles involved and how to make it as safe as it can be with various redundant backups.
All I'm proposing here is a simple diving bell that's big enough and comfortable enough to spend some time in.
Hello /diy/. So I got this electric motor that a uncle gave to me and I'm trying to repair it. I have almost no electric skills but I thought that with your and youtube's help I might have a chance.
So it has been under rain for a couple days, so it got water in the electric cables. I took it apart and dried all the components, but this capacitor seems like was gone, so tomorrow I will buy a new one.
Anyways can it be fixed guys?

Was there anything wrong with it before he gave it to you?
>>945727
Actually I don't know, but it was pretty beat up and since it was under the rain seems like I should change the capacitor, shouldn't I?
Hi does someone has good resources/ material to share about arm development? Like which files is necessary and how t osetup new project if talking about STM32. How the fuck should i know which files is necessary to setup and include to code? Lets say i watch youtube tutorial, but i wanna understood how t odevelop stm32 project, why i need to do su much crap only to blink LED and etc.?
Best regards for people whos gonna help me
Btw i wanna learn C programming not mbed or assembly
Try to analyze libraries and etc from STM stdperiphlib

Is this your first time programming microcontrollers (or programming in general)? If so the STM32 looks like it has a steeper learning curve than, say, Arduino. It looks pretty cool though.
1. You need so much "crap", because you are building up from (almost) bare metal. But I think you may just be missing some steps...

Thanks for informative link.
You see, i wanna learn to program in C. mbed is like arduino. Assembly is far too dificult for me. Why I want lo learn program embedded in C? Because i wanna have balance between using efficiency of resources and development speed. In my opinion embedded C>> mbed IDE like AVR-C>>Arduino. Btw sorry for poor grammar, english is not my native language
I was given a Raspberry Pi 2 as a gift some time ago and I was really excited when I got it. It was fun to tinker with but ultimately I quit messing with it so much and it has been sitting in a closet for some time now.
A few days ago I decided to pull it out and see if I could use it to watch some stuff on my TV without having to connect the HDMI cable from my computer.
My experience so far has been as follows:

Is your only interest consuming media? If so, you have to realize that you are limited to what will run on the Raspberry PI, unless you are willing to do some work to get what you want. Its a SoC with GPIO: you have a computer with OS and GPIO, so you can do *anything* a basic computer can do. It just isn't built in. However, there aren't any arbitrary restrictions either (like with a smartphone).
If you want to do more than consume media;...

BTW, that's kind of the whole point of RaspberryPI. One higher level of abstraction than a microcontroller; one lower level of abstraction than a computer or built-for-consumption device.
Hey /diy/
I'm trying to make a bridge for a physics project and I'd appreciate any input
Rules
>pasta is the only building material
> no glue allowed, only water
Make a bridge of pasta and water.. Suggestions?
Use spaghetti and use the sam tehnique they use for baskets. You can boil it a few seconds so it softens. After cooling it stays in said shape.
>>950040
Like a weave pattern?
Could you link me to anything that will help in doing that?
More information

My fluke temp before damper is 550° F
Some people say thats too hot should be around 450°. How fo i bring my temp down.
Its an oil fired burner

What does the manual for you unit say to do?
GOD DAMMIT HOW THE FUCK IS THIS DIY RELATED
You haven't built anything, you're not replacing anything, you're just asking questions on how to work an appliance!!
DELETE THIS SHIT BEFORE I REPORT IT. READ THE DAMN MANUAL OR GOOGLE IT, DON'T SHIT-POST THIS CRAP HERE GOD DAMMIT I'M TIRED OF SEEING SHIT LIKE THIS ON DIY. AS AN AVID CONTRIBUTOR TO THIS BOARD PLEASE KEEP /DIY/ DIY RELATED, THANKS.
>>949894
GOOGLE that shit retard.
So today I thought of about playing CSGO and while waiting for the game to update I thought of going on facebook
but instead of the usual google.bg site opening this site opens
I open my options menu in Chrome and it says that the default search site is WebSearch wich is bullshit
after an hour I tried everything to remove this WebSearch thing off my Chrome but to no successes
So /diy/ what should I do ?
Help me out here
Note right now Im running a complete system check with the anti-virus
Ive unistalled all plug-ins from Chrome
Ive unistalled and reinstalled...

i had that once and it was so hard to remove i ended up reformatting. good luck man and try /g/ if /diy/ cant help.
>>949487
Install. Malwarebytes.
And stop going to ashemaletube
You're pretty fucked op. You'll have to reformat no matter what.You'll never get it all off any other way.

So I want to make a multi sensor to measure the following things in engine oil.
>diesel
>water
>anti-freeze
>soot
>metal particles
Wat do?
How do I detect the percentage of each contaminant?
I need ideas.
>>949259
a spectrum device on a glass tube or something similar, but this is hardly diyable
>>949284
>this is hardly diyable
That's why I want it to be a multi sensor.
It's easier when you're just measuring one unique property of each contaminant.
>>949291
No dude, the way you detect minuscule contaminants in oil is with a spectral analyzer which is stupid expensive lab equipment. It's soooooo much cheaper just to pull an oil sample and send it to get tested that "diy-ing" a spectral analyzer into your project (I'm assuming your truck) is objectively a bad idea.
Dear /diy/, I'm an apprentice electrician.
Word of this gets around to my friend who purchased a totally disconnected massage chair off craigslist.
He totally believes I can connect everything and get it working, wouldn't even take no for an answer. So I googled the serial number got jack shit. I phoned a few massage chair companies to see if they can trace it but I'm now informed that companies purchase a base model and stamp their company logo on it so it essentially means nothing.
I can't find any instruction booklets online.

Hey guys, I just unburied an old well at my house, apparently not on record. It's really shallow as wells go, I can see water down about 8-10 ft. Can anyone recommend a good pump that would be able to self prime this distance?
Why does it need to be self priming?
>>946082
It wouldn't have to be. I could get a cylindrical submersible pump you shove down the pipe but they usually start at 300 bucks, and want 220v power from what I have seen. Seems like that might be overkill for this setup though
http://www.homedepot.com/p/1-2-HP-Cast-Iron-Shallow-Well-Jet-Pump-SWS50/100030457
Why not just get one of these? This will pull from 10 feet no problem
Go to garage sale
Find a set of rust wood chisels for $1.00us.
This 1/4 inch chisel has the some issues with the edge.

Try a rotary tool to grind the tip flat then resharpen. Any pics of the grips OP?
>>950084
Sharpen it back up. Maintain the main bevel. Apply a microbevel to finish it off.
Using the fine grit wheel on the grinder
Match the angle of the bevel
Be careful enough so I don't over heat the steel and destroy the temper.
Lightly touch the tool to the wheel.
Anyone know what these are made of?

Thank you so much
When I studied electricity I always had this question and no one answered it succesfully.
So we have the Ohm lay that states that Intensity = Voltage / Resistance, and then the Electrical Power that states that Electrical Power = Voltage * Intensity.
Which is cool.
Now if I run a phone charger with an output of 5v and a wattage of 1W I can get a max Amperage of 0.20A
And if I run a computer PSU with 300W at 5V I get a max amperage of 60A
But what determines the Wattage itself. Like in this case, if I am trying to shortcircuit the phone charger...
Comment too long. Click here to view the full text.
I is current, not "intensity." The load, ie. the resistance, determines the amount of power drawn from the supply, assume constant voltage. Pretty much every power supply you will encounter is intended to operate at constant voltage. Notable exceptions include battery chargers, because batteries should be charged at constant current, not constant voltage. But this only applies to ones the charge the cells directly, not phones and laptops and things.
No computer power supply is going to be able to source 400A of current, and good thing, because you probably would have killed yourself. It likely has current limiting circuitry so it doesn't blow up when some idiot like you tries to short circuit the supply and turn it on. If it drew 400A through a resistance of 0.03 ohms, you'd be dissipating 4.8 kW in the wire; you already mentioned that your supply was 300W max. A well designed supply will do what yours did. If you were less lucky the supply would be toast, possibly with an electrical fire if you were less lucky.
Use heater element wire, like nichrome or something, which is higher resistance.
>>947619
Obviously I haven't done it with a computer PSU. I tried a modem PSU that probably doesn't have more than 1W.
I am trying to understand how it is possible that despite trying to shortcircuit (which is what you more or less do with a hot wire foam cutter) the modem charger it allow more current.
Since you said that normal power supply units normally operate at constant voltage, in this case 12V. Supposedly if I reduce the resistance(shortcircuiting) I should get higher amperage.
measure the voltage at the output of your power supply as you short it. it will be very low.
P=V*I
if any of V or I is low, the power will be low.
the keyword here is internal resistance of the power supply
most of the voltage drops internally
