I'm going to put up OSB paneling in my shop. Should I spring for R13 insulation for an extra $200-230 while I do it? Here is a heat loss graph I made. I ran a heater 30 min to get from 40 to 72 then let it run down for 40 minutes. Outside temp was 38.
Depends on you, friend. If you spend plenty of time in there and want to stay warm without the feeling that you are wasting cash, get that insulation in there. Insulation also pays off in keeping things cool so when summer comes around you might be a clever crafter and frame in a window opening to fit a window AC unit or just a vent for a standalone AC. Now you can putter around with soldering irons/saws/imprisoned girls rain or shine, summer or winter.
Absolutley, I've built a few houses with 2×6 on all exterior walls simply to stuff more insulation in them, I blew in 18" in the attic, Execpt for a glass patio door the doors were doubled at the main entrance and garage, very well insulated from the basement and the two largest windows were triple paned.
I fucking love insulation, in fact I'm insulated right now.
But really I abhor working with fiberglass and will never do it again if I can help it, it's the Devil.
so I've decided my next project is going to be building a basic 4 piece drum set (2 tom toms, a snare and bass drum)
I'm hoping to use pre made shells, as i havent got the tools or space for those tools to make them myself. Im struggling to find a place to source the materials i need. does anybody know where I can source drum shells, lugs and hardware of custom size in the UK?
also anybody who has built their own instrument would be great to hear about it, any advice on my project would be appreciated
>>920448 Why does the hardware need to be custom? Why not use "replacement" hardware? It seems asinine to get a 14 inch rim custom made for a pre made 14 inch shell. Same thing with the lugs and tuning screws. It's just going to be a lot of extra money to get this stuff machined when parts that do the same thing will do the same thing.
You're probably not going to find this stuff locally, an if you do it'll cost more than what you can find online.
Since you are buying the shells, you can... oh, you are buying the lugs.... oh, you are buying the hardware. I guess you will diy the skins? If you are buying the skins too, you may as well just buy a used drum set on ebay that has the kind of shells you want, and do some finessing/finishing to make them sound and look great to you..
I asked over in /g/ (technology) but didn’t get any replies, so I thought I’d hit you guys up for an answer as it is kinda /diy/ issue;
I recently got a pair of wireless Bluetooth headphones (iDealUSA) so I could listen to music off my computer (Mac Mini OSX El Capitan 10.11.02) while taking care of chores around the house, including down in the basement such as doing laundry.
Problem is, despite the claimed 10 meter range of the headphones, the audio cuts in & out due to interference from floor joists, heating ducts and whatnot blocking the signal.

google says no. http://superuser.com/questions/247868/do-bluetooth-repeaters-exist At least not for A2DP. No demand for it.
You could take your computer and put your music on icloud or onedrive and stream it all from your phone via an appropriate app or two. Not sure if google drive does it, but I would suspect it does. I know onedrive is quite nice about it. All my stuff on onedrive is automatically in my music apps on all my devices.
There are ways on the RF end to improve reception, but aside from relocating the receiver to a more convenient location, most of them will require some hacking/amplification/swapping of the antennas and thus probably won't be 100% legal (assuming US jurisdiction and no radio license).
I want to build a centrifuge for projects and kitchen stuffs, I've got a few options over spending $300-$3,000 on a professional one.
I'm not skilled enough to buy the rotors and circuitry so this is a superficial DIY- buy something that spins like a dremel or blender, and either botch it or in the case of the dremel, create an attachment. I can do the attachment part myself, some tips and ideas are welcome but my main thing is I have two concerns:
leaving a dremel on for 5 or more hours at 20,000+ rpm, good or bad?
Dremel has less torque than... Comment too long. Click here to view the full text.
>>920322 400ml of fluid is over half a kilo to spin. With a dremel or the like that means balancing needs to be done properly. Try to figure out an attachment and balance it very well maybe with the cell phone method where you run an app and adjust the rotor accordingly. Using falcon-sized centrifuge tubes also means the tubes need at least to run at an angle, preferably with a pivoting attachment so that whatever you are centrifuging won't wash out from the bottom when the centrifuge stops. And with larger tubes the... Comment too long. Click here to view the full text.
>>920355 I'm not sure what the cell phone method is but thanks for the info. I didn't like the 3d printed version because it has no pivot and doesn't allow for the vile to rest, which are both safer and more efficient.
if you could help me out one more time before I hurt myself, I was wondering how a string or chain would fail to balance perfectly, so long as the speed was adjusted slowly enough for it to not wrap around whatever the spindle would be?
in other words, viles A and B were attached... Comment too long. Click here to view the full text.
>>920497 Try searching for it. Balancing cell phone app rotation or whatever you know the drill. There is at least one instructable about it. I got seriusly drunk between posts so I'm trying to follow your train of thought before I forget this thread. One problem with a string/wire approach might be turbulence or wobbling. The centrifuge tube might wobble during rotation in a way that you can't see/measure it. I'm not sure if this is an issue but consider it. Wobbling would prolly reduce the effectiveness of the g's you are trying to achieve. A fixed stand for the vials might eliminate the risk of problems like this. I'm a molecular biologist so I have hands-on experience with these machines but no clue about designing of them. Off to sleep, fuk I'm fukt.
I'd like to build my own soundboard. Never attempted anything like this, but I'd like to make all the circuitry and stuff by hand. Has anyone had any experience with stuff like this? Am I in over my head?
What kind of sounds are you looking for? Simple beeps and sirens can be done with oscillator circuits using chips like the 555.
Almost any microcontroller can play WAV files because those are just a sequence of voltage levels you dump to a DAC to play the sound.
There are also some chips designed specifically for applications like yours. ISD1420 can record and play up to 256 different sounds so long as the total duration is less than 20 seconds. This was used in 90s toys like the yak-back and billy bass. SPO256 is an alaphone chip used for things like speak-and-spell... Comment too long. Click here to view the full text.
>>919682 Do you mean a mixing board like pic related or a single-channel mixer? It's the same circuits either way. A mixing panel is just several single-channel mixer circuits combined so you get multiple outputs mixed differently. Potentiometers are arranged in a grid so the Y-axis is your different inputs and X-axis is pots controlling the different mixed outputs.
You want Stereo, so you'll need dual potentiometers. These are two separate potentiometers controlled by a single knob. You're working with... Comment too long. Click here to view the full text.
Gullets only serve to eject saw dust so I wouldn't worry about the deep gullets, they may prove to be beneficial. You definitely do not need a rip blade on a miter saw. Ive had good luck with the Diablo combo blades.
Dedicated blades have different tooth configurations and different grinds so that's why they cut different. A rip blade should be around 24T while a xcut blade will be anywhere from 32T on up depending on what youre cutting (plywood, softwood, hardwood).
(sarcasm)I know how you guys love these kinds of threads.
But anyways my brother in law has got 9 or so large old portable oxygen concentrators from work. and i am trying desperately to think of something I can do with them or their insides instead of just scrapping them. I already made an offer on the 120mm 110v fans and cages if he does scrap them.
Please /diy/ help me think up a reason to get more neat junk besides just concentrating oxygen.
I'll fallow up with some shitty pics of the insides of one he already tore down.
Need help, guys. I typically post woodworking stuff. Have recently become obsessed with electronics, but am admittedly amateur level.
Wanting to get into audio and build stereo/guitar amps. Am currently at a Frys Electronics in Atlanta to pick-up a Fluke 117.
My question that I'm hoping you guys can help with is wtf is the difference in manufacturers and materials of electronic components and the difference they can make. Frys has everything, component-wise, minus said tubes. But I hear their components are somehow inferior for most applications, audio or... Comment too long. Click here to view the full text.
>>919350 No expert but these things usually come down to tolerances and power ratings, you mostly would have to take their word for it as testing these tolerances would be time consuming and in some cases destructive. For example, modern microprocessors and chips are usually rated after manufacture for their stable speeds and what not.
Because the parts are probably expensive and require greater engineering knowledge to assemble than is available on a diy forum. You aren't going to get a bunch of shit from your local hardwear store and make a hovercraft u nerd lmao
>>920150 They just aren't efficient enough to be practical. Fuel is heavy, and anything that uses ground effect uses a lot of fuel to stay airborne; physics, unfortunately, works, and in this case it works against you.
I'd like to start up a new soap general because I have just recently started back into it. However I am a dumb nigger and don't seem to have soapdad's recipe sheet.
Let's make the opening theme of this one about how to help dumb idiots like me not fuck up.
I have done two batches so far, and I did them both the same way.
I tried to make castille soap. Just olive oil, lye (NaOH), and distilled water. I followed instructions very carefully and used brambleberry's lye calculator. Additionally, I ensured that the lye water and oil... Comment too long. Click here to view the full text.
I was looking at boat plans, and I was thinking very sturdy, long lasting inflatable mattresses would be just the ticket. Lightweight and very multipurpose. You could use it as a raft in the water, a bed in the ship, emergency lifesavers, and whatever pillows, cushions, and mattresses were left would be a slight deterrent against sinking... lol
A method to make ridiculously strong and long lasting inflatable items would be very useful in marine applications.
Plus, the industry NEEDS a way to make inflatable products stronger and more durable. I've never seen an inflatable thing last longer than a week or two with regular use. Not even mattresses.
>>918919 Unfortunately, making it sturdier also means increasing cost or increasing weight. Making it stronger is easy, you just make it thicker with the same materials or you use completely different materials that are far stronger yet far more expensive.
Nano materials are probably the next big thing for this type of use.
Hey guys, I watched a video the other day to learn how to forge a basic knife out of steel. The problem is the guy used a belt sander to make the bevel on the knife. I have all the tools and ability to make the blade, but I don't know anyone who has a belt sander and I can't afford to buy one. Does anyone have some sort of alternative to make a bevel?
You can look on Craigslist for used sanders. Also check auction sites. For example I got an industrial Baldor belt sander for 75 dollars (overkill for your needs but large is good!). You can also use a bench grinder if you must.
An angle grinder and a few flap discs can also work well for smooth metal removal. You can find grinders used too.
An angle grinder is more versatile than a belt sander and with cutting discs and other accessories can do many jobs.
Wear a face shield when using any grinder.
