I live in the American Southeast, where red clay soils make up most of the soil in the area. Wikipedia says the red color comes from a natural abundance of iron oxide within the soil. Could I realistically find concentrations of iron ore around here? Has anyone here ever into prospecting?
Got water damage in my laptop, bought a new motherboard, because I switched it on to soon. Now I disassembled the laptop and found corrosion and a burn mark on the video card(see pic). What should I do? Clean it with isoprop? Are nylon brushes ESD save or should I use horsehair?
The video card is toast. Sorry bud. Look at the chip (CH) just north of the burn. It's discolored. Most likely from the chip annealing due to heat from a failure.
Now some systems can run without a dedicated video card. Mainly those with i3-5-7, if you assemble without the card it may work. However assembling with the card is a 99% chance of breaking the new Motherboard. If there is a burn mark on any contact NEVER PLUG IT IN!
Found a water cooker (solis 585) with many temperature and time regulating options. Its not turning on (no led or LCD). I was sondering what would be the most likely part that is ging to break. Any ideas?
I have been gifted a 1996 Yamaha Waveventure 1100 from a family member. It has been sitting, uncovered, for 10 years in a field. It was winterized before it sat, I am told. Upon a visual inspection, nothing seemed off, although I have not bothered to turn the engine over yet.
Family member says it SHOULD run if I put a new battery in it. I want it to run, and I hope it does, but what process should I take to insure success and reliability for the future to come?
I do have experience with 2-stroke engines, but not much and nothing over 50cc scooter engines.
If you can, find a manual of the internals. Then change the battery and see if it runs. If it doesn't, take it apart and clean everything and fix loose wires, etc. If it still doesn't run, try and troubleshoot the individual components.
I have no experience with waverunners, but this is my go-to solution for fixing anything I don't have experience with.
I'd just pull the plugs out and ground the spark plug leads so they are not running into an open circuit. Probably good to get some fresh fuel and oil through the thing as the old 2 stroke oil leftovers will have gone thick. Drop a little fuel oil mix down the plug holes and let... Comment too long.

hey /diy/, I think i know what i want to do with my life
I wanna be that old guy who can fix anything and build anything in his shop in his garage. Mostly carpentry and woodworking stuff I'm interested. I also wanna go to Antarctica as a carpenter. It's legit, watch Antarctica: A Year on Ice and the Encounters at the End of the World. There's carpentry jobs there.
anyway, I'm young as shit and only decided this recently. Hopefully I can get into this carpentry class I'm trying to take. Any advice to learn more and further a career... Comment too long. Click here to view the full text.
>>1049429 The problem is that you need years of experience and training in different fields. I can run a CNC router, rebuild an engine without a manual, build an a frame house on my own- but that took decades of bouncing from one job to another (whenever I got bored or mastered what I did there).
I have a Crimson Trace LG-431 laser. I'd like to install a small forward facing white-light LED in addition to the laser. It seems that this is possible using the same pressure switch, battery and driver used for the laser/photodiode.
Right now, it seems plausible that I could install the LED in series or parallel with the laser diode, if the operating voltages are similar enough to get reliable operation.
However, I have poor intuition about such matters, and I understand that even minor and transiently exceeding the voltage and current limitations of diodes... Comment too long. Click here to view the full text.
LEDs usually are fed from a current source since they operate roughly at constant voltage over a wide range of currents. The color of the LED is proportional to the voltage drop; higher energy photons (blue, and "white" [which are actually just blue LEDs with a phosphor that absorbs blue and phosphoresces yellow] LEDs) means higher voltage drop than low energy (red LEDs). So if you just stick one in parallel, unless it's exactly the same type of LED as the laser (which it won't be) only one of them will light up, the one with the lower voltage drop, as all...

>>1049349 Thanks for the reply. The board does have a potentiometer, which I think may allow me to increase the amount of current available after adding the LED, if that won't fry something else.
But that does still leave the problem of the mismatched voltage drops. It seems that laser diodes often have a voltage drop of ~1.5-2V. The only LEDs that operate with a similar voltage drop are non-high intensity red (~1.7V) and maybe high-efficiency, low-current, high intensity red (~1.9V).
On the upside the operating... Comment too long. Click here to view the full text.
So I broke a lot in my cars engine a couple months ago. Long story short, the camshafts have a lot of wear, my pistons are chipped, and valves are broken. I have 2 camshafts, and 6 pistons, and was looking to make something cool. I was thinking a lamp with the pistons as feet, and the cams as the shaft. Any ideas?
I am trying to do some crafts with epoxy, but I'm not finding any help for my specific project; it's got some unique criteria. I also don't know the difference between epoxy's.
I need an epoxy that can cast in thick globs relatively quickly, so my assuming is that I can add more catalyst than needed. lets assume that I don't care about cracking, can this be done with any epoxy or is there a certain kind I should use? It doesn't need to be crystal clear
Yep already have the psu (it was free) and it has a maximum of 30A output on the +5v line so 20A should be fine, the main problem im having is how to control the voltage so i can make it output 0-5V but have that controller handle the 20 amps
>>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
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... Comment too long. Click here to view the full text.

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.
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.
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)
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.
>>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... Comment too long. Click here to view the full text.
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.

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... Comment too long. Click here to view the full text.
>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... Comment too long. Click here to view the full text.
>>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... Comment too long. Click here to view the full text.
>>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.
I have an aluminium plaque that I need to clear the oxidation and paint from. The paint is corrosion resistant. So far we've tried white spirits, nail polish remover, and some regular paint/varnish stripper. White spirits did nothing, the nail polish remover seemed to soften the paint but it's not very good. We're currently in the process of trying the stripper, but it doesn't seem to help much either. Has anyone got any recommendations for a)stripping the paint from the nooks and crannies of the etching on the front, and b)removing the aluminium oxide buildup?
I recently won a Siemens Simatic S7-1200 PLC with software license in a SkillsUSA competition. I'm learning to do PLC programming as part of my degree, but I'm at a loss as to what I should do with this thing. I was thinking about putting a switch panel in my car to control various functions, but this PLC needs a 24v supply and my car battery is 12v. Is there any way around that? I've also been thinking of an automated bong system, but I'm not sure if it would be viable. Any other ideas for a project I could use this in?
>>1048039 Pretty sure they use a drill, anon, maybe an end mill. But if your main concern is how to make the touchhole and not "how do I keep from blowing my ass into 5.23x10^11 pieces," you may want to think about the whole scheme a little bit more.
So, guys, im in the middle of swapping my cars engine and i do not know how to connect alternator and starter. I've got engine wiring which is quite a bit cut - most of plugs are gone but i managed to figure out whats what. Now, the engine is 1.8 K-Series rover engine, no vvc or turbo. There are 4 wires left - brown-violet (x2) brown-yellow(which i presume is control light on dashboard for alternator) and white-brown. Any mechanics could help?
