Hey guys I plan on building a cabin soon. I am pretty lost on what design and such yet but I do have a question that's been bothering me.
On something like pic related, what's keeping moisture from getting into the vertical wall boards?
I would imagine it's insulated inside between another wooden wall.
But wouldn't moisture cause rot and mold and such?

For vertical wood siding you have to use a moisture resistant and rot resistant wood like treated cedar or redwood. Its more costly, but the look is there for the vertical battenboard siding. But eventurally, it will fail sooner because of the buildup of moisture.

Theres a few DVDs and books out there regarding tiny-house designs. They're essentially light duty trailers as the base built into a house structure. If its for a long term placement, you essentially level it and block it in like a manufactured or mobile home.

Wouldn't horizontal boards run into the same issue? There's no way to leave them exposed and totally sealed right?

>>902741
I'm not buying this, I have an old cottage (built in 1912) with the original pine siding. By now it's starting to look the part but that's a hundred years later. Possibly in a very humid climate but OPs picture makes me think that's a non-issue.

This said, I have no answer as to why the place hasn't rotted. Some steps on the way to make it work are:
- Locking panels (no gaps for moisture).
- A breathing paint (don't want moisture trapped in there).
- Cutting the planks...

Hey /diy/, quick question. Looked for a QTDDTOT thread but found none. Anyway:

I'm building a semi-permanent shelter out in the woods on a friend's property and I have it mostly completed except for one thing: a fireplace.

Now the whole structure is something of a wigwam debris hut, it has a wooden framework that i wove with flexible branches and then covered in bark and leaves. Obviously I need to put a little time into how to safely have a fire inside for cooking and heating.
I was thinking of getting some kind of chimney to route hot exhaust and...

I've been getting into crochet recently as a way to pass the slow hours of the night shift. This is my latest work in progress: a circular rag rug crocheted from a ball of bedsheet strips. It's a lot easier than I thought it would be. I think I'll try making a rag basket next.

Do any of you other /diy/kes crochet, knit, sew, or practice other fabric crafts? Show off your creations in this thread, ask other anons how they made their stuff, etc. Anything goes.

Biggest factor is actually _where_ you're building it. In the Seattle area we're pushing no less than $100-150 per sq. ft. If you go to Eastern Washington near Idaho, these prices drop by about 40%.

So,

Whoever did the plumbing in my flat didn't give enough room for the toilet inlet pipe & after a year of awkward strain it has started leaking. Turns out he'd cut the end of the flidmaster to fit but not left a flat surface and I'm guessing its done some damage to L valve & washer.

Already replaced the fluid master & the leaks still there, should I get a long flex hose & loop it around to avoid any more strain? Don't own the flat so can't do anything about where the pipe comes out the wall.

Thoughts?

Yeah, me neither. Scotland, think the owner of the flat 'finished' up the job on his own. The pipe leading out of the wall is incredibly loose and I've no idea what's going on behind there. I could just replace this setup but it's putting a lot of strain through the wall. Don't want to risk that.

Want to set up a valve & flexible compression hose but there's hardly any room for it to go.

Indicated on the photo where the leak is, cheers!

They are externally linked via a jumper you can snap off. Look on the sides, it will be between the two screws. Also, it's parallel.

>>903956
All outlets and fixtures on a service branch are in parallel.

Think about what would happen if they were in series. Your reading lamp plugged into one outlet would get no power if you unplugged your phone charger from the other. Hell your phone charger wouldn't work unless you had your reading lamp turned on.

Cont. Afterthought...

A GFCI receptacle plugs are parallel, but they have a line and load side that you have to be aware of when writing it up. You'll know if it's GFCI because it's a fucking brick of a receptical that can be a pain in the ass to fit into the box.

hi /diy/
need to drive an led at various levels, can't have it flash though. even at high frequency.
currently i have pwm into lpf to get basically a set voltage, resistor to get a current then transistor as an output driver. led can eat around 1A@2-4v when hungry.

apparently i'm stupid because i should use a mosfet instead of a transistor to reduce power consumption. I have read about 7 or 8 things about mosfets but they might as well have been in chinese.

Why can't you have it flash?
>>
If you're using your transistor as a constant current source, both MOSFETs and BJTs will dissipate pretty much the same amount of power.
PWM (flashing) drive has much higher efficiency.
If you want both high efficiency and reasonably low ripple, you need some variant of a switching regulator. There are specialized ICs for driving LEDs that way.
>>
Not an expert on electronics but you can try using a high pass filter on the drain side of the MOSFET. Most of the heating occurs at the low frequency components of the waveform. The high pass filter also doubles as a current limiter.

Alright, simple as this. Will thermite reaction, produce an almost pure form of iron, or is there aluminum mixed in? assuming I use aluminum and iron oxides.

Today I was sitting around staring at a wall, and thought of this. what happens if you made a simple greensand mold and put a tall cylinder on top of it, and cap off the cylinder with some sort of lid, then packed in tightly the cylinder with thermite and placed the cylinder back onto the mold. and lit it. Would it cast iron?

Well if it doesn't absorb into the iron, it turns into a slag of sorts.

I want to develop a custom control board for electric unicycles, currently they all have chinese made ones with no open source software and appalling quality. Most appear to be using a ST 32bit stm32f1 series chip. Amusingly they don't even use this chip to run the motor controller instead adding a second microcontroller to manage the the timings for the 3 phase motor and hall sensors.

The good thing about the STM32 controllers is that the evaluation boards have a debugger and programmer on them. You could get a STM32F4Discovery board which has an accelerometer on it. Generally the F4 series have an FPU (great for spatial calculations) and it's fast (up to 168MHz). For control of the motors you could use dedicates ICs (not MCUs). TI and co. have ICs which are 3phase controllers w/ integrated mosfet drivers and they accept a PWM pulse as input. Then you could simply use DMA (or software) for controlling a timer peripheral.

STM32 seems like the most popular choice. I'm a little lost on the motor controller though.

None of the controllers go anywhere near the volts/amps I need.
Do I just connect the controller output to another layer of larger mosfets?

If I use a controller like this it handles all the regen braking circuits? All I have to do is pass Engine / Brake and reverse data to it?

any of you /diy/kes do any home demo/renovation work? I have a place built in the 30s that I'm having tested for asbestos (ceiling tile, plasterboard, flooring) and I'm shitting bricks.

Best just to keep asbestos covered up and pretend it doesn't exist. You get fucked having to remove and then dispose of it.

Like the other dude said, its really fuckin expensive and just fine if you leave it in place and put another material over it.

If you're removing flooring throughout a small 2 bedroom house, expect a $5000+ bill to get rid of it. Not to mention a few hundred dollars just to tell you what you already know. A special company with special licensing removes it, and then they take it to a special disposal site. Its NOT something the average home-gamer is legally permitted to do. Same goes for any materials testing positive for lead.

For flooring, you're...

You get 'daylight' (light-spectrum emulating) bulbs, but they are really, really fucking white and not what your wanting at all.

Just use a mixture of different sources, lower wattage, proper incandescent bulbs, pref. on a dimmer - maybe, some uplighters, 2nd hand shop will have something old-school with a heavy shade - LED's are really, really, not what you are wanting either, srsly.

I've just been learning how to use these. I have one IC and I've powered a string of LEDs with an Arduino, then moved onto driving a 1 digit 7 segment LED display and then a 4 digit version with multiplexing.

Now I want to elaborate with multiple LED matrices to make a large (at least 24 by 24) matrix (out of 8 by 8 ones most likely).

What are my limits with a single Arduino and its 5V supply, if I start daisychaining shift registers to drive such large displays?

At what point would I draw too much current?

>>901539
with a shift register like that you can put all the leds on at the same time.
usually with more leds you make them into a squareish matrix, have a string of shift registers on the x and a separate set on the y.
turn on the leds one row or column at a time

then you calculate the power drawn from a single row or column because thats the maximum draw at one time

max draw from arduino is probably like 1A or something have a look at the regulator see what its rated at.
