Anyone use software and a mic to tune their piano? i've got a tuning hammer, and i'm gonna borrow a friends laptop so i can try and use the "Entropy Piano Tuner" http://piano-tuner.org/ that creates a stretched inharmonicity tuning for you after recording all your keys. i guess the idea is that by randomizing the variation between keys, you create a piano that doesn't go out of tune as fast, as the tunings drift, they're not as distinguishable or something.
I'm looking for a cabinet to store my shit in and I don't have the expertise or tools to make a really nice one for inside the house and not just some makeshift one in the shed or backyard (I want something simple and rustic).
How do you figure out whether the prices you see on kijiji or craigslist is fair when there's no retail equivalent to compare to?
>>1073593 Buy a nice used wood dresser at an estate sale or something. I have two. I paid $40 for one and $55 for the other. They are both 5 drawer highboys, similar to your picture, but 'waterfall' style. They are wood with veneers, so loads better than the new particle board and paper shit you see most places. You gotta shop around for the deal, man.

Hello, recently i bought an electrical oven, it warms up nicely, however there's a huge issue with it- the oven is incredibly loud, it's almost as loud as a washing machine. Up to this day i've always had gas ovens. Is this normal for electrical ovens to be this loud ? (it begins to be loud 20-30 seconds after I start it to work). If it is not normal, what can be damaged inside ? Best regards, Dynio
Maybe just a home-mad satellite that I can send signals in the air. The title is a joke, but I still want to send signals with it. I have: One foot of thin copper wire from head-phones, two old intact phones I don't need anymore, one TV that can't produce light so I don't need it anymore, a pile of hangers, a pile of forks, and sheets of aluminum. Any help?
If you use soap packets you can just put them in the bottom of the dishwasher before you start it. I have done this for years since the little hinge/door thing on mine broke. It's not worth repairing, all it does is open immediately when you close the dishwasher.
I need to know about circular saws. I need to cut some metal with very straight lines. I have my fathers old circular saw which specifically says not to cut metal or use abrasive blades. I see plenty of circular saws on Amazon(picture related, thinking about buying this) but they dont say if they are approved for metal cutting. There are some that say they are metal cutting but they want 400 dollars for that shit.
>>1072732 This is pretty much how I started out, you could also look at CL and see if there are any cheap there, if you are attending a gym and they have a notice board then try putting a notice up asking if anyone has a cheap one for sale.
You could also try asking on /fit/ although I don't know much about that board or how helpful they are in general, and just in case anyone here has a cheap/free bag you might like to list where you live, you town and country.
So I'm getting together the materials to do some backyard metal melting and molds.
I've got access to a lot of metals and wish to turn them into ingots, mostly for the space
Now the problem is not the different furnace designs...I've already chosen a design to make.
The problem is the walls of the inner furnace. I can't find a single furnace wall mixture that everyone can agree on. Everyone has got their own recipes but which do I choose? which one can help me forge the ring of power in the bowels of Mt. Doom?

>>1072514 I have the kit from Foundry101.com, and don't regret it. The walls are a ceramic insulation fixed to a wire mesh frame. The top is steel over ceramic insulation. The bottom is refractory, with a steel pipe tuyeer. The burner runs on Propane and is easy to start.
It's expensive, but I enjoy this far more than the charcoal one I made previously out of furnace cement and perlite.
At the lowest cost end, its hard to go past a DIY mix of perlite and waterglass (sodium silicate), as that will last quite a few dozen burns - typically you'll end up damaging it through klutzness before it gets too heat damaged and you can buy enough material for several furnaces for around $50.
Perlite from the nearest hydroponics (or even garden) store, and waterglass either purchased or home made from that crystal kitty litter and caustic soda (see youtube for videos on making it).

So my neighbor wants me to landscape his yard and is paying me a few thousand dollars for materials and labor...but I'm not a contractor and I don't have a license. In the state of California any project that cost more than $500 requires a contractor's license.
Do I risk the potential legal hassle to make a quick buck or what?

So I recently came across a genuine hakko 936 soldering set when I was helping clean out a lab. The controller is busted which is probably why it was hiding in a box in the closet and not being used. The iron is still good and I'm thinking of making something like pic related which is a mobile soldering station, runs off any voltage like from a car or lab power supply and even RC batteries.
When I look up 907 controller on eBay I'm given dozens of variations, does anyone have any experience with these things or recommendations? Or even any info on diy versions... Comment too long. Click here to view the full text.
would this all be possible with a single arduino? i know very little about them and never used one but im willing to learn how to wire and program it. basically this stemmed from wanting to electronically control the throttle of my diy generator engine (yeah im that guy from before) to keep it in the efficient rpm range when the electrical load starts to slow the engine down. i thought that since im already going through the trouble with the throttle and im going to have the other sensors anyway i might as well hook them all up to a controller and have them output to a screen...

Absolute noob here. I made a small circuit on a breadboard by following a tutorial, but they didn't cover how to go from being on a breadboard to being soldered together. The board's grouped by rows, so do I just solder everything that's in the same row together? So for example, all the negative terminals are on row 16, so I'd wrap all those together and solder them, right?
would one of these make an ok fuel tank for a generator? i installed a fuel pump on it so that i can use a larger tank than the small gravity feed one it comes with and i can get as my of these as i want from work for free. is there any way i should modify it for safety?
my story starts in early march of this year. frustrated from years of just cruising through life, i was looking for something to do that wasnt work, that i could learn a lot from and obsess over. a project with clear progress and a clear result. a project that would involve a lot of problem solving, a lot of time, and would be something i would be thoroughly proud of.
a project car was my natural solution. now, having no car at the time, i had to find something close... Comment too long. Click here to view the full text.
I'm going to build a metal roller and I would like to take suggestions. The basic design is this, I'm considering adding another arm on the other side, but I like the idea of an open top roller. I wanna be able to roll 1"x1/4" flat bar, and 14 gauge sheet metal (on a 4" width). I belive that I can get away with not having another arm for my rolling requeriments, what do you think? I was going to simulate it on SolidWorks, but apparently you can't do it with assemblyes.
>>1065258 No I'm not that dude. I'm taking the basic design from this comercial one, which takes 1 inch by 1/4 inch flat bar. Mine is more robust, the arm is half inch by 1 1/4, and the piece where it pivotes is more robust also. It's true that in my design I have 4 inch long rollers, but it shouldn't make a difference if I roll the 1/4" flat bar at the back. And with 14 gauge steel I belive I won't have that much deflection.
So /g/ is full of people who hate fun. Anyone here do any PC case mods or custom cases? What have you done or wanted to do?
Pic related is my current PC. Modifications I've made are: Painted the inside red Removing the molded plastic grill to make room for a better dust filter I swapped out the HDD LED for a brighter one, changed one with a slow color changing one, and drilled holes for 2 new ones to make a sunset lighting. Removed the front "grill" and cut out some plastic to help with the front fan from suffocating.

>>1074346 Don't explain what, explain why. The general rule is if you have to explain what then your assignments are to complicated and you should split them up, but if you feel like going rogue then don't worry about it, leave them complicated fuck it. But certainly you should explain why instead of what Don't be afraid to comment on a block instead of line by line if it makes sense.

The problem with introductory programming commenting some of it really is too dumb to bother commenting, but teachers will still want it because it's so hard to find anyone that comments code properly later in their career.
Not sure if this is the best place to ask, but I'm looking for adding color lighting to my apartment, and I have no idea what kind of equipment to use. I've been looking for a while but there's always at least one thing missing, the only viable solution is to go through companies to that install it for you, and that's way too expensive.

>>1074168 There was a pretty cool bulb I saw on Shark Tank. You replace all the bulbs in your house with it and download their app which controls the bulbs via bluetooth. You can do mood lighting, party lighting, synch it to music, have different settings for each room etc. It looked pretty cool.
Hmm maybe modify a "NZXT hue+"? They provide 2 channels and it's all controlled through software on your pc. The 2 channels are independent from each other. If you could make so it can handle bigger strip lights and connect the strips to individual outlets then your set. Curious as well.. I have a great led fetish
>>1074111 TEGs are very inefficient at generating electricity from heat, and you'll need a significant temperature difference to get anything useful out of them. i red somewhere that even having a hot air engine with a dynamo is still more efficient than a TEG,
>>1074111 >>1074122 >>1074132 TEGs are fine when you have a lot of them together. They are a good solid state solution to waste heat electric generation. They are easy to install and have little maintenance. Their only draw backs are initial expense and low output per square foot.
Fluid-based PV panel cooling is also a good option, but requires a lot of space just for the heat exchangers in both removing the heat from the PV panels and placing it into whatever device you want to use to make electric with. This type of cooling is better used for heating potable water for domestic use in houses than for making electric in a van (if pic is related.) Faults and failures in the system become very messing and troublesome. In cold areas, you must have 2 fluid circuits if heating domestic-use water. One is antifreeze and the other is the domestic-use water. For non-domestic-water use you only need the antifreeze circuit. The best electrical generation would be to use the fluid system with a Stirling Engine of rather large diameter. Remember that all parts of the system except the heat exchangers must be well insulated and have active flower using a pump (the pump will eat up more electric efficiency). Thermosiphon flow can't be done efficiently when the heating is at the top of the circuit.
Costs for the fluid-based system will ultimately be higher than the TEG system for the amount of watts you will be able to attain. Costs also include maintenance and time spent designing, maintaining, and building a non-standard fluid system.
Using only air instead of fluid would be a waste of time and effort.
All cooling methods for PV panels will increase the efficiency of the panels and extend their life.
So i had an internet cafe more than 10 computers, have since sold off most of my hardware but still have like 6 17" 768*1024 monitors, is there a cheaper way than using 2 triplehead2go adapters to run my 6 monitor video wall?
Gonna take the casing of and weld up a frame to hold my 6 monitors 2 high, 3 wide.
Using a gtx 960 4gb that can technically run 4 monitors, but my monitors are old vga and dvi a, don't want to have to deal with 20 adapters to use only one triplehead2go, just want a simple to setup solution.

Hey /diy/, newbie diy-er here. Does anyone have any knowledge on CONIA TVs?
I've had this one for a while, picked it up for cheap due to it making a buzzing noise whenever it's on. Never really had the time to get around to fixing it, and just used it anyway. Now I was wondering if there was a way I could fix this.
From what I've gathered it's a busted capacitor, but I'm more or less useless when it comes to this stuff so I'm wondering if anyone has an idea of where I should start. I know it's tied to the contrast/brightness... Comment too long. Click here to view the full text.
