Hey I just bought a new home, and after construction is about finished, I noticed that my property slopes away form the house a little more than I expected (I know it has to slope away a little to help with drainage, but see attached. My question boils down to weather or not I am being too picky, or is it worth it to regrade it a little before I fence in the yard. I am a newbie to landscaping, so go easy on me. Thanks!
>>969124
try that again
whether, and yes
>>969128
yes I am being too picky, or yes I should grade it?
Some MIDI controllers (like APC40, Behringer BCR2000, Livid Instrumets, etc) have rotary encoders to control virtual knobs that have 128 positions.
Im searching about rotary encoders to make a DIY MIDI controller based on Arduino, but i only find rotary encoders with 20/24 steps per turn, i cant find a "128 steps" encoder.
How can a "20 steps" rotary encoder send 128 pulses per turn? How this MIDI controllers works?
I have never seen one that is thru-hole/board mount (like OP pic) that had more than 24 pulses. They wear out relatively quickly too, and don't move smooth because they have detents in them.
There are rotary encoders pretty cheap on the China sites. Looking fast I didn't find any with 128 steps per turn, most are 100, 200, 400 or 600 steps.
If you got a 400-step one then you could just use 3 pulses of the encoder as one 'actual' pulse, that would take 384 pulses on the encoder--which is pretty close to one actual turn.
Do note: the types...

>Figure $400-$500 at least, for just a 128-pulse unit.
Okay,,, I was a bit high in that estimate.
Here is an Omron-brand 256-pulse absolute encoder at Mouser for "only" $301
http://www.mouser.com/ProductDetail/Omron-Automation-and-Safety/E6CP-AG3C-256-2M/?qs=TwPrcXezm71FKQKJ%252bh0w3g%3D%3D
Omron makes a lot of different rotary encoders, but (looking on their website) the 256-pulse one is the lowest-pulse-count absolute one they appear to make.

You can have 128 positions or any other arbitrary number using a 24 step per rotation rotary encoder. A rotary encoder turns continuously and you keep track of position in code. You can count as high as you like before rolling over. You'll have to do multiple full rotations to go from 0-127, but that's fine if you show the number on something like an LCD display instead of printed on the panel behind the knob.
What would I need to do to connect a slab of wood to my window like pic related?
I've been wanting to add a second section to my desk area for my laptop workstation, and figured this would be a good way to do it without losing the floor space underneath.
>>968716
So without ANY kind of support under it? You will have to hang it from the wall or from the ceiling. Particle board will sag like a motherfucker under its own weight without support, let along with whatever will be on your desk. Even plywood or real wood will do the same with time and weight.
I wouldn't exactly call particle board a slab of wood, but....
you're pretty much going to have to have some kind of support to keep it up....keep it mind it doesn't have to be much, and it doesn't mean you'd have to put posts down to the floor
there are plenty of designs for simple brackets with 2x4s, or you could just use metal shelf ones
>>968716
Add square metal brackets to each side using screws and glue to prevent to board from sagging. Screw the board down.
Should be fine.
What should i use for legs on a wood table? I have made a couple of table tops before, but i never had to worry about having to make legs.
the legs dont have to be made of wood, i was thinking about using some small metal pipe to give the tables a modern rustic look
meanwhile can we get some cool woodworking ideas going? i need some ideas for a auction i am in.

Hi /diy/
Are electronics hit by lightning salvageable in any way ? I have his receiver or whatever it is here and it was supposedly hit by lightning, but I can't see any visual damage like blown caps, any idea how I can start troubleshooting without damaging the equipment beyond the damage that's already been done or killing myself ?
Pic related, psu of device
>>967896
Lightning is a bitch.
As far as troubleshooting goes, just measure everything that you can.
Start with the diodes, move up to transistors.
The ICs are very likely shot.
These are called varistors.
They are usually connected directly at the mains.
Some times in series with a shunt resistor. When high transients occur, it will route it back, so your circuits are safe.
When the transients have more energy than usual, the varistor will break.
And most of the time if it breaks it will stay shorted.
Measure the resistance across the varistor.
If it is low (5k is still low) it has blown. Desolder the varistor and measure the resistance again. If the resistance is high, you are safe to plug your circuit in the mains and check...

>>967903
Don't confuse the varistor (connected in parallel with the mains) with an inrush current limiting device like a NTC thermistor which will be connected in series with the mains and should have a relatively low resistance (like 5 ohms). They are in very similar packages.
I want to replace my damaged copper water pipes with pex, is this a good idea and do I need any special tools?
Usually copper is pretty solid and stands the test of time. What do you mean by damaged? Just a section or the whole pipe its self? Need more specifics. Also yes, pex does require special tools to make the fitting connections.
>>967212
pex is also much more expensive than copper. and it will break down with exposure to the sunlight. it has its place. and its easier to use if you can buy fittings in bulk and need to thread a pipe through a wall. copper works well though.
if you just have some pinhole leaks just buy a new section of copper pipe and solder it in.
The original installer probably used copper for a reason, you better make sure pex will hold up under the conditions
So I've just got a kit with cutting, heating, welding tips, hoses, regulators, etc. My main question is about the tanks themselves, as well as actual welding methods.
>better to buy or rent the tanks?

>where to buy or acquire weld rods? I've heard of people using bicycle spokes and other random shit like clothes hangers.

you need to say what country you are in, different countries have different laws about owning and operating gas welding equipment

Right, sorry about that.
Good ole America! Where the eagles fly free and the burgers are juicy.

i also would have accepted "Where the burgers fly free and the eagles are juicy."
Hey /diy/, first time posting, but I have this tomohawk thats in need of renovation.
So it's a pipe hawk that my uncle gave me when i was 12 to smoke weed out of, and its served me well so far, but got gunked up. So i took it upon myself to boil it in hopes of getting all the resin out of it, and make it useful again.
This resulted in a wooden stem that's dried up so much that it has new air holes, and a metal bowl/blade that looks like its been left outside for the last 200 years.
how do I go about making it look good again? pic related is what...

citric acid in warm water
leave in for 2 days
>>966518
this will... do what exactly? will it help the wood, the metal, or both? also how long will it stay fixed? I already tried scrubbing the metal, but as soon as it dries it just goes back to looking like this, Except with fingerprints and watermarks
and how do I keep the water warm for two days straight?
Imagine you are there in the middle of nowhere and you found;
How to make fire
How to build a house
How to fees yourself
How to make clay
How to make charcoal
And suddenly you find a Copper Ore
How can you make copper wire out of copper ore?
In case you cant, what are the minimun tools in order to make copper wire?
OP here
I think that if you somehow managed to make a cilindrical ingot of copper, you could make a rock anvil, scratch a straight shallow line, and hammer the ingot down into that line, until the wire traps inside
one day Primitive Technology will make copper wire and build an generator to produce electricity and then build e-Motors and power tools
For those who might not be aware, this is a tv series about the zombie apocalypse and one of the characters plans to set up an ammo manufactory and to that end, plans to renovate the small shop shown in the following pics.

My question; what’s the boxy machine in between the radial arm drill, the suspended cauldron and the bridgeport; a planer or a sheet metal brake or what?

Not bad, but it's no Dewalt™ brand Dewalt™
I've been thinking of building a hybrid cpu cooler by drilling into the heaptipes of a cheap air cooler and using a cheap $3 pump off eBay for better cpu cooling.
Has anyone tried anything like this before? Any advice before I start ordering things in?
The cooler will be something like pic related, the water will pass through the copper heatpipes.
http://s.aliexpress.com/6zERriYR
Still looking at heatsinks for the cpu, so far it looks like I can save around 10 dollars by ordering from China
http://pages.ebay.com/link/?nav=item.view&id=221809121186&alt=web
That's the pump. Going to hook it up to the computer psu.
A little more than $3 but whatever.
Overall it should cost around 20 dollars, including the hoses, since I have a mate who does water filters and shit who's willing to help me out with that.
>>970820
You do realize that this is bound to leak everywhere, right?
Are water softeners a scam?
>>965132
If you don't know what hard water is or haven't noticed weird things like white residue all over your laundry or how you can never get your car clean because the water itself leaves stains that are almost impossible to remove when dry then yes.
>>965132
They do work. Depends on what you are paying for them I guess.
>>965132
Ever see someone jump off a bridge or something and hit the water hard? Always happens in natural bodies of water like lakes.
Water softening is used in community pools where diving boards are involved.
I'm not sure if this should be on /diy/ or /ck/, but I need help making some fake bones; enough to produce a rough approximation of a human skeleton.
Back story: my brother and I do Sunday night dinner together most weeks as a way to keep up with each other. We alternate turns cooking each week. Over a couple of years, we've both developed some decent cooking and presentation skilz, and have tried to out do each other several times. Easter is going to be my next turn.
Suffice it to say, neither of us are religious people. Even still, I'm planning a religious themed easter dinner. Basically, I want to build a human corpse to represent jesus, and then the different courses would be served from the corpse directly. For example, I want to cut the head open with a dremel (largely for show, not much real cutting) and remove the 'brain' to serve as a pate and crackers course. I want to slice in to the abdomen (and a plastic bag concealed within) and scoop out the contents to serve as a Ramen with mixed vegetable course. Etc...
Anyway, I have this recipe for 'fauxtex' which will make plenty of fake skin to cover the corpse with. I really just need an easy and cheap way to make the skeleton. I don't even need a whole skeleton; I'm thinking just a long spine section, the rib cage, and the pelvis. The serving area is only so big. I already have a plastic skull that I can make the head out of.
I guess my real question is how can I make the rib cage and pelvis? It has to be accuratly shaped enough so that when you drape the fake skin over it, the final appearence is real enough. Can I make some plaster of Paris casts for the ribs? Can I use animal bones avaliable at the butcher? Can I do a little of both and fuse them together somehow? I looked up plastic skeletons that I could disassemble, but the cheapest one that looked like it would do the job was $100 and out of stock. I tried party city, but they don't have anything Halloween at this time of year.
Wet some pasta and let it dry out. If you want, get a balloon mold of sorts and wrap the pasta around it so the ribcage sits nice and evenly. You might need to make a frame for the pelvis(with pasta of course) and drape large areas with pasta sheets. If you're serving them with something wet, you can try putting foil or cling film as a layer between the food and the bones, or wrap the bones themselves.
Sounds like a fun time, OP.
>>964172
Not a bad idea. Wasn't there someone here recently who had to build a bridge out of pasta? I wonder how well that turned out.
I don't have any great suggestions for you as this is out of my limited /diy/ realm but I just came here to say your idea is awesome and so are you. I really hope you post pics of your progress and the result, I want to see this more than liam hemsworth's dick (which is a LOT btw)
i wish you all the best of luck in this man
