Welcome to /diy/, a place to:Post and discuss /diy/ projects, ask questions regarding /diy/ topics and exchange ideas and techniques.Please keep in mind:- This is a SFW board. No fleshlights or other sex toys.- No weapons. That goes to /k/ - Weapons. The workmanship and techniques involved in creating objects which could be used as weapons or the portion of a weapons project that involves them (e.g., forging steel for a blade, machining for gunsmithing, what epoxy can I use to fix my bow) may be discussed in /diy/, but discussing weapon-specific techniques/designs or the actual use of weapons is disallowed. Things such as fixed blade knives or axes are considered tools, things such as swords, guns or explosives are considered weapons.- No drugs or drug paraphernalia (See Global Rule 1). If you want to discuss something that could involve such things (e.g., carving a tobacco pipe from wood) that's fine, but make sure it's /diy/ related and doesn't involve drugs or it will result in deletion/ban.Helpful links:https://sites.google.com/site/diyelmo/ (archived)http://www.engineeringtoolbox.com/
Some friendly suggestions for posting:- First ask Google, then ask /diy/. Your question will probably be better received if you do so.- List available resources (tools, materials, budget, time, etc.)- Try to use pictures and explain the goal, if possible- Be patient, this is a slow board; your thread will be around for days.- Share your results! /diy/ loves to see problems solved and projects completed!
Disclaimer: i’m not planning to do anything of this. I don’t suggest trying any of this stuff without proper guidance ,knowledge and preventive measures. Main questions: is it possible to make a safe, small scale reactor capable of providing energy for a medium class home? How much would be it’s price ?How much knowledge would be needed to handle such a device? Would a housewife be able to handle it with newly developed technologies?And if an accident happened:How large would be the area of effect?
>>2784959Yes, it's technically possible to make your own nuclear reactor. Assuming you have the capital to fund it, the engineering, physics, and electrical knowledge to construct and operate it without killing yourself and your neighbors, and the means to attain the fuel and dispose of the waste properly. However getting thrown into federal pound-me-in-the-ass prison for a long time isn't really worth doing something that might break even in cost in like 2 or 3 decades.
>>2789677I've got some particle emissions for her to detect.
>>2793581Your “average voter” depends on the country + at some point there will be programs to automatize some or all process related to nuclear porwer= household wifes in japan will be able to operate that stuff in the future=

I want to translate and bind books, (not on an industrial scale) because in my country, they aren't available. How do I do it?
>>2795557>>2795562Is it just scale of printing hundreds of books that people choose to spend thousands or tens of thousands to get a company to print and bind their books?Surely there are some inexpensive automated binding machines that could make a small print worth it.
>>2796164For perfect binding you could do it pretty quick with nothing but a clamp and a hammer and scissors.If you want to actually stitch h journals together and shit, you're already into it as a hobby, not to be making books. You're looking at a drill or saw or dremel now and some curved needles. You need to upgrade your clamp so it can hold thongs while you stitch.
>>2796167Thanks

>>2795546grab a needle and threadprobably the simplest way
Just finished this deck, step thing for an old mill on my property. Please r8
You ran the decking the wrong way as wellNobody wants to see the ends of the boards walking up to the house
You start at the front and work towards the house so your odd width board is against thehouse.A good carpenter doeshis layout so there is no odd width board….ITT IDIOTS..nice looking pallet hahahahah
>>2796311Seems like the only thing you diy'd in your life was your reading ability.
dude what is your flashing even trying to do
>>2796257Nails??
Devastated actually. I grouted my tiles with a mid grey grout. First part I did a few weeks ago and I was afraid it was drying out too quick so I kept spraying it as it was drying. It turned out streaky. This time, I just let it dry and 36 hours later it’s crumbly and dusty. What the fuck?? How can I fix all this? I wouldn’t even know how to apply it correctly now.
>>2796293> streakyAhh, this explains the problem. Grout is supposed to go between tiles, not on top of them.
MURACIDTIC,.
>>2796301>>2796303No you’re misunderstanding… the cloudy layer on the surface wipes off ok. It’s the grout lines between the tiles that are fucked up. They are patchy in colour and crumbly
>>2796317Did you use the right grout? There’s sanded and unsanded. Sanded is for bigger gaps, unsanded for small stuff. Youtube goyim I followed says he did like 50/50 mix and I did that plus the liquid sealer after it dried and mine was ok.
>>2796293Also how it’s crumbling like that on the top and that gap, to my armchair handyman eye who has done one tile job, it looks like your grout mix was way too dry and/or you used sanded grout with granules too thick for those gaps. Like you had air pockets and not enough wet sloppy grout forced into the gap.
Do they literally just blow warm air over the food?some of them cost over £500. I already have metal boxes and hot wind isn't exactly hard to attain.
>>2795548>How do you make a freeze drier?A sub-zero freezer that can be sealed and a vacuum applied.The 'real' ones cycle through temp changes and pressure changes but vacuum freezing is mostly it.
>>2795541>as the voltage going through it heats the element, the resistance changes, it gets higherYeah, that's the resistance temperature coefficient. But the actual resistance curve for any given temperature is a straight line, not the curved line in that graph. If you wanted a resistor that changed resistance based on voltage (e.g. for soft clipping distortion of an audio signal), an incandescent lamp would be a poor choice, it would only have that behaviour if you changed the current/voltage slow enough to let it heat up. For fast (e.g. audio) signals it would just act like a normal resistor. The temperature coefficient is actually useful in some circuits, like for stabilising a sine oscillator, but the graph and your statement implies it has a nonlinear I/V curve like a diode. It does not. I am mostly just being a pedant.Interestingly enough though, when Edison was experimenting with carbon filament bulbs, these filaments were made from carburised bamboo. This charcoal structure actually had a negative temperature coefficient, and the bulbs kept dying from thermal runaway. They had to roast the filaments in a kiln, this changed the structure of the carbon into something more like conventional graphite, which has a positive temperature coefficient and is stable with a constant-voltage source. The original filament would have been usable with a constant-current source, or with a current limiting ballast capacitor/inductor.
>>2795765aaaaah ok i get you now.the temperature is only going to change slowly, so for higher frequencies it doesn't do that.in other news i have one bulb in my dehydrator now and am thinking about where to put the other fans.if you look at my above photos you can see i made accomodation for 3, in a horizontal row, however i want some lower fans, i think maybe just two aligned vertically might be better, thoughts?
>>2792179due to government regulations and food safety standards, modern dehydrators do indeed 'just blow hot air over the food' which partially cooks it, evaporates some moisture, and kills surface level bacteria.if you want to be a purest, you can dehydrate food with literally just the wind, and if you want to be a cheap diyer, you can dehydrate food with just a regular box fan with a frame attached to it. My first attempt at dehydrating jerky was the box fan/square tray method and the food was perfectly edible. Drying after all, is simply the act of removing moisure via moving air. But the added heat does speed up the process and removes a lot of doubt. In the preindustrial era, drying would be achieved by setting up meats in the air on string and letting the air blow through it but that would take days if not weeks and required good luck with the weather. A modern heat-utilizing dehydrator can achieve the same thing in hours. It's pretty unreliable, which is why most cultures then transitioned to smoking meat which.... is basically blowing hot air through the food to dry it out while inccidently flavoring it as well.
>>2792710i had that model, motor burned outbought a new model, its double walled, same price. 10x better. not riveted, doesn't vibrate or shake, can actually touch the outside.
How's your local makerspace? Mine is awesome. I mostly just show up to work the desk every week for 1/2 discount, and talk to randos about all kind of things, but also I've finally dipped into woodworking and the laser cutters.
MURACIDTIC.

>>2796300>Not happening in yeehaw IndianaYou say that now. Summer vacation is just starting.
>>2796252>IndianaSee, those are the engineers who came from Michigan and Illinois and escaped the taxes of those hellholes.Per capita is whatever. I’m sure the makerspace is still full of fegs but maybe it’s just right for you. I did a quick google maps to see what was in Ann Arbor and Champaign/Urbana, 2 of the Top 5 schools in that stuff and both in the Midwest, and it’s exactly what I would expect. Lots of them are in basements because sunlight would kill half the people who go there.
>>2796300Honestly that’s probably better than a college town where all the nerds make their LARPing gear at.Pic related is the most highly rated one in Ann Arbor, MI, right off the UM campus and that’s a big engineering program.I feel like MIT/ Boston could have one where some super genius makes some cool shit, but then anything that interesting would have to be hidden before somebody else runs off to a silicon valley startup firm with the idea. A real life Bill Zuckergates.

>>2795996Don't bother with a beam at all. Sure, you can make a hexbeam relatively simply with trial and error for under $400, and it'll be the same as any commercial variation. That said, ~50ft of RG8X, a rotor, and a homebrew mast would start pushing you well over $800. I'd suggest a multi band vertical or making/buying a fan dipole. A good 3-6 band fan dipole will be a sufficient antenna for almost anyone. You can easily make 3 30ft pushup masts, then put one fan dipole N/S and the other E/W, using the same center mast for both ends. Don't run them in series, just use 2 feedlines to the radio or a switch. That avoids the need for a rotor, and you can horizontally polarize both fan dipoles.This guy did the same thing using a cage fan and traditional fan dipole. The beautiful thing is that the elements shouldn't interact much, so you can actually go 160-6m with the same dipole and feedline. In theory.
>>2796002You don't need site prep. You dig a hole 5x5ft, place your tower in, level the tower, and fill with bags of cement and a garden hose while tying the tower down or attaching it to a house, wall, etc. Make sure it's level before leaving it. I used to work for a tower install company and this is literally what we'd do, if you have the blueprint for your home or have an available copy you should know where water lines, septic/sewage, gas, etc run. If not, a survey only costs an additional $50 for us to call 811 and mark utiliy lines (a free service in the state). We actually used quikrete because most of the time we couldn't fit a cement truck on site. We did have a pickup with a 50 gallon water tank, however, as well as hundreds of feet of hose hookups.
>>2796011not him, but that's awesome.I'd love to get a few acres and setup an antenna farm. I was hoping with a ghetto harbor freight concrete mixer I could pull it off myself. just gotta get land and maybe used towers.
>>2796002Another asshole who has no idea what he's talking about, cute.
Is there anything wrong with getting one of these mounts and sticking a 10ft pole in it on the roof and running a bolt through? Will it hold a 2 element 10m yagi?

>>2796230> gold platingDon’t worry, they have gold plating down to 1 atom thick, so it’s not like the plating was compromised.I can see most of my recent 1/4" and 3.5mm jacks with gold plating wear off quickly and noticeably (definitely within a year).I’ve found that nickel plating suffices.> replaceable tipsThey used to have these, I remember them from the 80s. We’ve regressed!Generally, they’re going to get dull even without dropping them. If you have a power supply, some nickel, and some acid you can re-plate them with nickel at home easily enough. Useful for other things too.
>>2796225Put a resistor in series with the power to limit the current if running without TVS diodes.What’s a hard drive wattage? Like less than 1W?Thise TVS diodes also limit spikes from various sources, so never insert an ac wall plug to turn on the device due to arcing. Always use a switch, or, even better, some kind of soft-start mechanism.I don’t think the hard drive connector is “hot pluggable”
MURACIDTIC….
>>2796041Yeah, I’m guessing this is actually 60 Hz hum.Let me guess, the potentiometer shafts are aluminum and you’re turning them by hand.You’re supposed to put plastic knobs on them.You can probably hear this stuff if you have a headphone or amplified computer speakers.Add the smoothing capacitors as close to the ADC pins as possible. An inductor in series or a big ferrite clamp-on wouldn’t hurt either.

Planning on building a raised bed, should I place a tarp below, so the wood sits on it?Planning on doing something like pic related where it's surrounded by woodchips or gravel or something.
>>2795236I think using a tarp to 'prevent weeds' from growing up is misguided for several reasons>many weeds travel by air to grow on top soil anyway>impeding your roots from growing deeper than the length of your box height (8'' to 10'')>can cause water to pool at the bottom of the box, causing rot from the bottom up that you can't see>prevents aeration and settling>using plastic at all Just build your box and use old dry leaves and woodchips to cover the top soil around your plants and you'll cut down most of your weeds anyway. If you grow anything that has deep roots that tarp is going to severely hinder their development.Also, don't use pressure treated wood. I used untreated oak with interior brackets and it's lasted more than 4 years with only mild weathering.
>>2795243>>2795236>using plasticDo you fags really grow shit with plastic everywhere?
>>2796272I use cardboard
MURACIDTIC..
>>2796272its not my preference but i'll use whatever is available, depending on what im dealing with. If theres a really invasive propigates-through-rhizomes plant in the area im not taking any chances.

>>2796298I'm mostly made figurines and they came out well besides the first layer being a bit off sometimes. The pei plate fixed that. It has clogged up on me a few times and the hotend heating block being able to spin around when you unscrew the nozzle (which is what caused the wires to break) definitely sucks.
>>2796306So, would you recommend K1C printer or nah? I would print pieces for household and maybe carbon fiber enchanced parts for car and abs most of the time, or should I get some other printer?

>>2795193There's also price and learning curve.
>>2795193The thing is, if you’re going out of your way to use a debug probe, you’re probably savvy enough to not be using the Arduino IDE. At the very least use PlatformIO or vendor IDEs. PlatformIO kinda runs on Arduino code itself for some hardware, so beware. Better is to use (community made, FOSS, platform agnostic) command line tools and a text editor of your choice. They often support 3rd party programming tools, which is good because I’m not buying a fucking Atmel Dragon. More of a pain to get initially set up, but once your workflow is established it’s much more convenient to have all the configs already in your makefile. It’s probably also better for using other languages, like Rust.

>>2796223> unknown shit is even worse than known shit.Those are the shit that shit shits.FTDI is probably already working on bricking them, software updates for FTDI drivers should be disabled permanently. The main problem that made the chinese clones shit was actually FTDI.The CP210x likker guy in >>2796210 is right, use the SILabs versions, they’re as based as Texas Instruments.
