Who farmer here?
I'm growing tobacco for the first time. It's exciting.
Tobacco is shit to grow. You'll probably fuck it up anyway
You got the climate to grow it?

Do honeybees count as livestock here?
Pic related, it's my babies in their homemade hives.
I have a slate kitchen floor, and it's had 30 years of neglect. Chemicals aren't touching it, and I need something more but don't want to damage it.
I used a wire brush and it worked marvels, but its a lot lighter in color and the tile sort of turned chalky.
Can I just do this on the whole floor, and reseal it with an oil or acrylic or am I going to do more harm than good?
you took a wire brush to slate because you're too stupid to buy a proper cleaning product?

masonry is polished after manufacturing prior to packaging.
you just removed the polished and opened the surface on a porous material. now your disgustion pig hoof sweat are going to stain them. good job.
OP here. I bought a commercial stripper. There's years of some 'wax' thrown on for a sheen and was never removed. Lots of embedded dirt and grime that. The commercial stuff just couldn't touch.
Everyone knows it's a godforsaken pain to try and change a laptop GPU (if not impossible).
But for fun and knowledge how hard is it exactly?
I guess this is a soldering thread
For the record, no I'm not attempting to do it I just want to know what /diy thinks.
>>1048520
it will be a reflowing job, so it will depend on your oven and your skills, but unless you already have such equipments i.e. oven, solder, etc, and have experience in reflowing it is often not worth it because it will be almost impossible for a first timer diy to not fuck up.
>>1048524
forgot to mention, you need special solder balls specific for reflowing, which is another thing you have to buy, again, its a huge pain to set up correctly, unless u are pro, or you are just doing for fun and dont mind fuck it up, it is not worth the hassle and risk

You're using foreach incorrectly, and you appear to have a typo. Rewrite line 9 to this:
for (String s : sport.values ()) {
Note the difference between local field sports and class field sport.

I need the lid of this trash can to be able to rotate fairly easily, as if it had bearings. Can you help to come up with a simple and hopefully cheap way to achieve this?
>>1048485
get some actual bearings and then put them along the edge
A bearing.
Alternatively some sort of grease.
Also alternatively two rings of some low friction material like Teflon, but I guess that's basically a bearing anyway.
>>1048485
get an R2D2 and transfer the insides to the trash can so you can rotate its head while you rotate the can
I want to wire up a UHF radio (car unit) for home use. I can get a generic plug in the wall adaptor that will output the voltage I need for like <$5 on ebay (pictured). I know I need 12 volts, but my question is about amps.
The unit has a 3 amp fuse, so that means I want less than 3 amps doesn't it? Because 3 amps will blow the fuse? So I should be looking for a 12V, 2A adapter shouldn't I?
what happens, if your radio needs to draw 2.5A to operate, but your power supply is only rated at 2A?
>inb4 probably nothing
your power supply will get warm, overheat, and (eventually) die. Your radio is fused at 3A becuase thats how much it needs - the 3A is the lowest-rated fuse at which it will operate before a problem (eg short-circuit) means it will attempt to draw more than 3A, and the fuse will blow, protecting the Unit.
So, having said all that, what you need is same or higher power supply, eg, 3A or more, less is bad. More is actually better, bit of overhead is good - the radio will only draw what it needs, and, in the event of a problem, the fuse will blow at three amps.
tldr - over-spec power supplies, not under - device rated at 3A? = power supply 3A or greater, less is bad.
>>1048436
Neato, thanks.
However it does say in the manual
"Over current protection - 2 Amp fuse"
Which I thought was odd that it would say 2 Amp FUSE rather than just 2 Amp, since it has a 3A fuse.
>>1048409
it wont draw more current than it needs. if it needs 3 amps, get 3 or more.
My fucking washing machine doesn't get hot water only at 40 degrees. It works perfectly at 60 and 90 degrees. Any ideas?

so a couple weeks ago my families smart tv died, attempted a fix with a new logic board but that didn't fix anything, so it's now trash. dad says he won't be able to afford a new one for a couple months, so i suggested just getting a regular flat screen tv with a raspberry pi hooked to it. but i have a few questions first.
>is android a good enough operating system for this purpose?
>will a wireless mouse be enough to navigate in android, or will i need one of those wireless keyboard/mouse combos?
any tips will also be apriciated.
what functions are/were you actually using on the Smart TV?
If its mainly HTPC, Pi and OSMC maybe an idea - https://osmc.tv/about/ - Linux tho, not Android.
If you were using it more for browsing, email and stuff, maybe better just using a PC + VGA monitor (+ buy TV-in box) as a temp solution
- time you buy all the bits for a Pi and a new dumb monitor (+ wireless keyboard, def need if email, etc.)- gonna cost you as much as new 'Smart TV' will anyway.
>>1048354
basically we just used it for netflix, youtube and streaming music. android has apps for all of those, but is there a better os for all of them. my dad also thinks that browsing the internet on his tv would be cool.
also, since it was a 32in tv, and my dad wants to go bigger, using a computer monitor or an old crt obviously wouldn't work.
For US$60 you can get an Android 5 or 6 box that will do everything you want including run Kodi.
I'd rather buy a dumb TV and use an external (replaceable) Kodi box than pay for a locked down Smart tv
Old safe I'd left long ago at my parents place went back to get it forgot it ran on battery and now it's dead. I've done some searching around for anything to point me in the right direction to no avail, shy of taking it to a locksmith I've no idea how to open it. There's no keys to it visible or screws I can take out. There's nothing in the safe, I just want to make use of it again.
tldr; safe with dead battery need open
best image I could find, model on the right.
cool story
These usually have a socket where you can plug in a power supply to reactivate the keypad.

Google/youtube for defcon safe cracking and some shit like that. They covered some exploits for a few of these safes.
I'm trying to make a binural mic with 2 condenser mics and a headphone cord, but I have no prior experience with wiring. A quick "this goes with this" would be much appreciated.
Apologies for the stupid question.
>>1048293
Does your recording hardware even let you record in stereo by like that? If you wire two mics to a regular PC microphone input like that it's still going to record in mono.
>>1048303
I'll be using a DR-05 so it should be fine. This guy made his with WM-61A's.

Im following this instructable http://www.instructables.com/id/3-Emergency-Solar-Radio/?ALLSTEPS to make my own solar radio, and im trying to use some laptop internal speakers i salvaged and trying to wire them to a 3.5 mm headphone jack but its not working, what should i do? pic looks alot like mine (i salvaged mine from a lenovo x220 tablet)
The output of a headphone jack can only power the very small speakers found in headphones.
>>1048308
Strange since it works when I attach the wires to this.
>>1048326
Then you fucked something up.
Hey /diy/, I'm building a potato cannon tomorrow and I was wondering in my state of highness if pic related would be possible with a piezoelectric igniter. Essentially the sparking units (bolts threaded into the pipe with a ~2mm gap at the ends) being wired in parallel. I apologize for my snapchat drawing skills.
Or would wiring the sparkers in a series be better/even possible? Would multiple gaps cause the circuit to not work?
>>1048287
A piezo igniter generates a spark that can jump [some distance], and the total distance it has to jump (over as many gaps as you want) has to be equal or less than that amount.
If you wired them in series and the total distance was small enough, it would jump all of them.
If you wired several spark gaps in parallel, then it would just jump at the smallest one and the others wouldn't do anything.
Most piezos I've seen only jumped like 1/16 of an inch. And really there is probably no benefit in using multiple spark gaps.
The fuel vapor tends to be heavier than air, so just put a single spark gap near the "bottom" of the chamber (when the cannon is held normally).
If you try dumping in a HUGE amount of fluid, it may not ignite at all as the mix is too rich.
>there is probably no benefit in using multiple spark gaps
Yep. It's a potato cannon, OP, don't overthink it. And things that make sense when you're high don't always translate back to reality.
I just had a baby and my cat was being a fucking asshole about it so we decided he lives outside now. He's gotten used to the great outdoors even though he doesn't leave the porch most of the time. Winter is coming up and I want to build him a little box home so he has a place to keep warm and stay out of the elements when winter hits. I don't care too much about how it looks and I want to do it fails cheaply. I'm not a complete idiot when it comes to wood working, but I currently only have a miter saw for cutting and a drill or hammer for fastening. How should I go about this? I was thinking something similar to pic related with 1x4s with an opening for him and then line it with a blanket or something. Thoughts or suggestions greatly appreciated.
>>1048243
Fairly** not fails.
>>1048243
Oh, and bonus points for it being slightly elevated with a tiny staircase because I'm a faggot and I love this little fucker.
>>1048243
>>1048249
If you loved the little fucker. He would be inside where hes not going to wander into the street and get hit by a car, or where an owl is gonna come by an scoop him up and drop him to his death from 100 feet up, or when coyotes are gonna pluck his fur out whilist still alive but mangled and feast on his dying bones.
But ya know, build him ur stupid box, because it's only there to make you feel better about your own decision. Nothing more.
I'm digging a drainage ditch around a cabin that has a BIG hill STEEPLY sloping towards it on one side, and believe it or not, there's a mold problem on the side closest to the hill. So I'm trying to get the crawlspace dried out.
I've already got a ~20" wide and ~12" inch deep ditch dug between the cabin and the hillside, which drains to lower ground. And it works: it fills up with water when it rains hard, that's water that was going into the crawlspace before I dug it.
Now, am I supposed to put a pipe and gravel in the bottom of it and cover it back up with dirt?
I don't think I should, I think it works better without a pipe and gravel because this way I can touch it up every so often when it fills up with silt/leaves/whatever. And it's in a very muddy woods so I feel like even the best french drain fabric and pipe would eventually clog.
But are there any actual advantages to having a pipe and gravel and all that in it? This is a cabin in the woods so having an open trench in the yard isn't a problem.
Basically this question is surface draining vs. subsurface draining, but I've googled the shit out of it and get nothing much more than agricultural shit so thought I'd come here in case anybody is knowledgeable about this and would like to help... thanks so much in advance.
I'm a house framer btw in case anybody has any questions they'd like to ask me in return
>Now, am I supposed to put a pipe and gravel in the bottom of it and cover it back up with dirt?
The gravel should encompass the drain tile (pipe). It should cover the pipe on all sides. There are fabric sleeves that wrap perfectly around the drain tile. Just tie a knot on each end. I'd go at least a foot above the drain tile with more gravel, followed by landscape fabric and then dirt.
>But are there any actual advantages to having a pipe and gravel and all that in it? This is a cabin in the woods so having an open trench in the yard isn't a problem.
It can probably be left open without worry. Eventually though, with the rainfall and erosion of the dirt, I would think the trench would fill up and would have to be redug to benefit as much as it is now.
>>1048236
I'm worried that the fabric would clog up much sooner than I'd want it to, the soil where this cabin is at is bizarre, it's super sandy fertile black shit that becomes impentrable muck during heavy rain. So i'm torn between doing this pipe and gravel stuff and worrying about it getting clogged, or just leaving the ditch open and cleaning the junk out every so often.
But I obviously want to do whichever way is more effective for the job of diverting water, so you think that the open trench functions just as well as it would with a pipe and gravel? As long as I keep it clean oc
>>1048240
>so you think that the open trench functions just as well as it would with a pipe and gravel? As long as I keep it clean
Yes, an open trench will divert the water just as well as the pipe/gravel. The pipe/gravel is best when you are going to cover up the area with dirt/grass etc as it is much easier for the water to flow through than dirt alone. Since you're not going to have a lawn or landscaping over this area, an open trench would work just fine.
