The challenge: sleeping facing down OR diagonally at a down angle, without anything touching the front of the face (except for chin)
So far I have come up with pic related, it works when I test it but when its time to sleep, I can't fall asleep and end up rolling over. I also put the pillow under my chin sometimes
>>1089968
Your head weights about 10 pounds. Having all that weight levering on your chin will hurt.
Look into pillows that will do the job. Or a massage table.
You can turn your head sideways
>>1089973
Tha'ts what the clamp is for. If you rest your side-face area on the edge of the bed, it's comfy but you need another edge to prevent it from falling.
The chin pillow is just extra support
Also, a massage table / pillow for it is like this except they put pressure on the forehead which i don't want.
Thank you for effort though
3D printing buildings
Whats the future of this? Mobile construction platform that you can rent for a few days to construct yourself a house.

3d printing buildings can be done in 1-2 day with current iterations. With future iterations, the platform would be cheaper, more modular, precise, faster, smaller

There are many potential advantages, among others the ability to construct stronger homes in rural areas without the need for bulky materials.
In a time where local human labour is becoming increasingly expensive, and modular prefab houses are becoming more common, squirting a house out of a nozzle is a natural next step.
If the process can be automated, previous "carpenters" can be set to operate a truck each, allowing the same number of humans to built ten times the number of houses.
Perfect for disaster response, refugee accommodation, student housing or affordable housing for section 8's.
At the moment, tech is in its infancy still, but give it a few years. Nothing keeping this from allowing people to buy cheap plots of land and "build their own" for less than the price of a man-made home.
So my dad hinted that he wanted a cigar humidor/cigar bundle from online for Christmas. I did a little research though, and all of the packages come with a shitty humidor, and only a couple good cigars in a mass of shitty ones. Who wants a humidor that is just spanish cedar connected with butt joints, and covered with thin veneers, coupled with an inaccurate hydrometer.
So, instead I am going to build a nice humidor, and pack it with all top of the line cigars. Knowing his tastes, instead of just using spanish cedar for the entire box, I am going to build out the exterior with Oak, and line it with the spanish cedar. I will mount both the hydrometer and humidification device within the lid, which will swing on a piano hinge.
>>1089775
I got it all designed with the final dimensions at 12"x8.5"x4.75", with 4.25" of the height being the box, and the remaining .5" the lid. The bottom of the box is set in by .25", so the inside depth is 4". The materials on the box, are .25" Oak, and .25" Spanish Cedar, so the wall thickness is .5" all around. So the final chamber size is 11"x7.5"x4".
These dimensions allow it to hold cigars up to a Churchill, which encompasses all but the weirdest gimmicky cigars. I also estimate its capacity at 30-50 cigars, depending on ring gauge.
The required wood:
>.5"x5.5"x48" Oak
>.25"x5.5"x48" Oak
>.25"x8"x48" Oak
The .5" Oak is for the lid, while the .25" Oak is for the walls, and it's diagram is pic related.
>>1089776
Here is the diagram for the Spanish Cedar. It is the standard for humidors, because it holds a lot of moisture, doesnt get moldy/mildewy, and has a great aroma. However, it's hard to find and I had to source it online- and it is EXPENSIVE.
>>1089777
Ignore the rocketry mandrill, the Oak is just in front of it. At this point I was still waiting on my Spanish Cedar, hydrometer, hydration device, hinge, grain filler, and I had yet to decide on the finish.
Hey /diy/, I'm a bit short on money this holiday season and was wondering if anyone could help me out with some ideas for gifts. Thanks!

From looking up every cheap 3d printer, the reprap variants seem to be the best bang for your buck.
Right now Im wondering if I should go cheap and get one I see for $175 or shell out $400. The latter would be a huge investment for me because Im a poor college student.

Secondly should I assume since they have hotbeds and a good nozzle that they will take any filament I throw at them.
>>1087981
If you're a college student, look into your school's engineering/tech labs. I'd find it hard to believe they don't have at least a few 3D printers. They'll likely be significantly higher resolution than what you can get for $400, and (if your school is anything like mine) all you need to pay for is the cost of materials.
>>1088004
We dont have one. Its a liberal arts college with focuses in science but not engineering.
>>1088007
That's unfortunate. Have you checked if there's a makerspace type thing in town? Those cheaper 3D printers are a bitch to work with. The resolution is typically awful, the nozzles clog like nobodies business, and the hotbeds are unreliable at best.
What are you intending to do with it? If you want to make little sculptures to sand down and paint, the cheap ones will be okay. If you're trying to use it for rapid prototyping or production parts (please don't do this), then you'll really want to use a higher quality machine.
Hey /diy/!
I work at a party cleaning/fixup service, and there are always a metric fuck ton of helium balloons left over.
I was wondering if there is a way I can extract the helium from each balloon and put it back into a metal or glass container for long term storage, preferably a hand pump run system.
Picture is a pencil shaped stabber thing that you put in the balloon and connect some sort of hose or housing to the threaded side for the helium to go to, i came up with it but idk what you would attach it to.
Ideas?
tnx
It could work if it's really thin, like a needle so the ballon doesn't pop. When working on the air-conditioner of a car you have to first pump out the Freon, then you can add it all back. The Freon is stored in a metal container, kind of like an air compressor tank. You might look into rigging up a system like that.
>>1086004
If you put a small piece of sellotape on the surface of the inflated balloon, you can then pierce it without bursting it. If not, it doesn't really matter how small a needle you use, it's gonna pop.
>>1086000
How I would do it
>build air tight box
>install a pump
>install a way to pop the balloons (electric spark maybe?) Without opening the case
>add balloons
>pump out the dirty air
>attach He tank
>pop blooms
>capture helium
Based on my middle school level knowledge of physics, your straw will only work if the pressure inside of the balloon is greater than the pressure of the tank.
Also unsure of the amount of stretch your balloons will take since they will expand under a vacuum, but that can probably be fixed by just adding more balloons per batch.

Uh, wat. Leatherman Charge TTI is the same thing except made with titanium handles and an S30V blade. You could have said that and lend some credence to your post.

I want to build an electric generator but have Nickie where to start. And any tutorial I look up yields a small generator. I want to be able to at least power 2 devices at once. And I'd like it to be human powered.
Where do I start? Do I need a permanent magnet?
>>1088043
Who's Nickie? You obviously type the name enough to have it in your autocorrect, so now I'm curious. Could it be a Nicole? Do you have nudes?
>>1088049
Seconded. I want to see nicole
Your question is small?
Irrelevant?
Don't know where to ask?
Are you stupid?
You've come to the right place!
Anyone know how I'd go about sourcing small blocks of burl wood? Locally ideally. I really only need like a 6"x8"x3" block to make a mount for a DIY oscilloscope I'm giving my dad for christmas
I want to build a switching circuit for diverting signal to and from guitar pedals as well I want to switch power on and off to the pedals at the same time.
Right now I am thinking of using an EDE2208 momentary to toggle ic and a couple of nlas44599's. I don't think that the nlas is capable of handling the necessary current through its switches though. Am I wrong? I am not very good at finding appropriate parts.
Are those aluminium electrolitic capacitors?
I'm interested in having an all tube guitar amp.
I'm no electrician.
Is it as simple as using a tube powered pre amp (Hughes & Kettiner Cream Machine or something like that) into one of these mini mp3 booster tube amps, then into a cab simulator?
Any suggestions about which pre amp/amp/simulator would be appreciated.
Or any suggestions as to how to build one into a single unit. A tone stack would be a big plus as I would prefer that to running a pedal.
Sorry the heading should be
All tube guitar headphone amp.
You clearly have no idea what you are doing. Not just electronic wise but guitar wise. I feel like you heard that tubes are cool and now thats why you want an all rube amp.
Yes you can make a tube amplifier and have it's impedance matched to a set of headphones. Why you would want to is beyond me.
It would take two transformers, a power transformer for power, tubes take a lot of voltage, and a output transformer to match the output impedances. You could even get away with 2 tubes in each section. 2 push pull preamp tubes and 2 push pull amplifiers. Lets say you use 2-12ax7s and 2-6L6. And with a handy little application of ohms and kirhofs laws, and a bit of biasing you would have yourself 3rd degree electrical burns and an arrhythmia that's probably going to kill you sooner rather than later Because you just got electrocuted with 800v out of your tube powered death trap.
You could achieve the same headphone amp effect with a single LM357 and a 9v battery. And skip the whole I don't even know how I got killed bit.

I have come into possession of a very large calrod heater. I know it probably goes to a very large reach-in/industrial cooler or freezer, but does anyone have any idea what brand it might come from, or can point me in any direction? So I can list it on eBay. Small calrod defrost heaters for refrigerators run $40-$60, so I'm guessing this thing is worth a good deal of change. Apologies, I know this isn't really diy, but I figured was best board to post on. Thanks in advance.
