360 submergerd in mineral oil

Well, I seen the instructable to submerge a PC motherboard in non-conductive mineral oil to cool it and brainstormed that this could be the perfect fix for my RROD problem with a early model Elite. I have drawn up plans and already found a few problems and would like some input on them. I do not expect a expert answer but I'm sure there are people out there that can make a far better assessment on this than I. 1.) Will the oil conduct and move enough heat to be more effective than fans? 2.) The case I have designed requires roughly 2.8-3.0 Gal of mineral oil and if i was to consider         circulating it through a radiator, what would an appropriate pump size be? ( gallons or liters          per min) 3.) Also I would plan on using only wireless controllers so is there a way to solder some leads       onto the sync button and maybe to an external momentary switch so I would not need access       to the MB everytime we wanted to add another player? Thank you for any help you can provide on any of these issues. Regardless I will begin work on it tomorrow as a experiment and to challenge myself. I will be making an instructable on this when it is done. And many thanks to the original author that inspired me to take it a step further. https://www.instructables.com/id/Mineral-Oil-Submerged-PC/

Efficiency of DIY bitcoin miners?

First, I would like to say that I do not know if this is the place for this question, but: I have just heard of bitcoin mining and started to look into it.  I have learned that pretty much the only way it is plausible is through the use of a machine dedicated to mining the bitcoins, not through using gpu's anymore apparently.  But I have seen that these machines are expensive, so naturally I would want to build a DIY one if I started this.  But are these dedicated miners even efficient? And what if they don't have the top of the line components?  I tried to look this up myself but I don't really understand the hash rates of these machines so I don't know what is considered an efficient rate.  And, in my current situation, I don't pay for electricity or internet so now would be an optimal time to do so and maximize profitability.  So, do these dedicated miners work efficiently enough to make it worth while to build/buy one? Especially if I don't pay for electricity or internet?

LED Music Submerged in mineral oil. Answered

I have seen led music cubes and prisms here but is it at all possible that you could make one that does light up to music in a plexi glass cube but filled with mineral oil? If I were to do this of course itd have to be sealed water tight so nothing leaks, but is there anything else that might need to occur? Per say would I have to add a dye to the mineral oil to get a good luminosity effect or would it be shining bright without it? If you could throw me some things that might be flawed in this idea or advice I would appreciate it lots!

How can I purify mineral oil?

My early experiments with oil-cooling my PC lead to some chemical *discoveries* The first was mineral oil will dissolve latex rubber.  I was using surgical tubing to pump the oil to the radiator and after a day the tubes had softened and swollen so much they wouldn't stay attached to the pump.  That and the oil turned an ugly yellow. (* the second was warm oil reacts with PVC, and causes the insulation on usb cables to become brittle) I'm working on the next gen of the project and I'd like to clean up the oil, but I can't quite google my way to a solution. I have filtered the oil (removed all the bugs) though a coffee filter, and a couple of paint filters, I don't have any reason to believe the rubber is suspended and filterable, but I could be wrong. Any chemists out there know what I can do?

How do you clean a dish washer?

I was wondering can any one give me pointers on this? Lately our dish washer is leaving spots on our dishes, glasses and est. I figure it is a build up of minerals in the spray and drainage holes of our poor dish washer since our house water system does have hard water. Even though we regularly use things like Jet dry to supplement the dish washing there comes a time where even that is not good enough to keep away crusty minerals. We had this dish washer for years now and never have issues until now. I plan on using a product like CLR in the dish washer but I'm not sure what to do next. Do I just pour the whole bottle of the product in the machine or do you pour it in a certain place? After I do imagine that I would have to let it sit in there and then run a few cycles? What do you guys suggest? Thanks for your input.  :)

How do I separate gold from surrounding ores

I live near the site John Marshall discovered gold in 1848.  There is gold dust and particles everywhere!  Problem is that the gold is dust or fine powder form and the gold strongly adheres to it's surrounding ores.  Panning is tedious and not effective.  How can I separate the gold dust/powder from the other minerals?  I have heard using Auger Regis is effective, but cannot find anything on how to use it, purchase it, or make it myself.  Any suggestions/instructions on making or using auger regis; or any other more effective method of extracting the gold from the other minerals is greatly appreciated.

Separate Sand and Water in Glass Vase

I'd like to hear some suggestions for separating sand and water in a 4" diameter glass vase. I'm doing an arduino project that involves having a dyed deep blue mineral oil as a non-evaporating "water" atop about 4 inches of sand in a glass vase. I experimented with drizzling Loctite epoxy and it leaked about 1/4" into the sand, so it wasn't very elegant (created a layered look - dry sand, wet sand, epoxy, water). I'd like the delineation to be as clean, but easily implemented, as possible. Worst case scenario is that I wrap something around the vase to hide the transition, but I'd like to avoid that if possible.  I suppose another option is to stack 2 separate glass vessels, but im struggling with thinking of a good way to do that too... Perhaps this is also a non-issue...I should see if the deep blue mineral oil is even visible if put directly INTO the sand. Thanks in advance.

In Spain, looking for clear teflon tube for a lightpipe.

I guess this question has two parts. I'm prototyping a solar energy device, part of which is a light pipe to transport the collected solar energy, about 300 - 2500 nM. I'm planning on making this from a flexible tube filled with a highly refractive liquid, stoppered at each end with clear plugs. It looks like the materials I should be using are: Tube: Teflon (PTFE, FEP, AF 1600, AF 2400) in that order of desireablitity, lowest to highest. The AF 2400 has a refractive index of 1.29, which is the lowest of any polymer. Apparently. Core: Mineral oil / liquid paraffin. Plugs: Acrylic or normal glass. Thoughts? Also, where would you suggest I try to find these? (I have the mineral oil already) Keeping in mind that I'm in Madrid, Spain. Getting this to work would make a huge difference to solar microgeneration, as transporting the energy is currently a bit of a nightmare. Thanks heaps, Daniel.

oil submerged playstation 3

Hi again iables, I want to build a oil submersable ps3 and have a few questions, 1. Will the oil degrade the silicone on a glass fish tank and cause a leak? 2. How do i extend the power and eject buttons off the motherboard? 3. How do i extend all other wires for the hard drive, power supply, bluray drive, hard disk drive and any i have missed? 4. What would be the best way to stop wicking in the wires from slowly emptying the oil? 5. Would any normal pc case cooling fans be ok to circulate the oil or would they burn out from the extra current draw? 6. Would a normal overhead fish tank filter be ok to use as a diy radiator pump? 7. Would this prevent the dreaded YLOD as iv already had it twice and fixed it myself, with relative success (about 2 months or 100ish hours), and this time im going to oven bake instead of heat gun as this method is rumoured to provide the best results, anyway i hope because of the even cooling provided by the oil bath, then it would keep it much cooler than air cooling? 8. What about using themoelectric cooling pads with huge heatsinks to provide extra cooling? 9. Would the wireless and bluetooth antenna's need to be extended or would they be ok submersed? i thought radio signals were blocked by water so is oil the same? If they do, how would i go about this? 10. Where would i buy mineral oil? I heard that Johnsons baby oil would work? 11. Could i use something similar to an undergravel filter in a fish tank to generate circulation if a pump head wont work? 12. What metal piping should i use for a diy radiator as i heard that mineral oil is very good at dissolving some things and im worried that the contamination may cause conductivity? I think that's it... if not ill add more when i think of them, many thanks in advance for any help!?

Researchers at Purdue have impregnated paper with iron particles, creating "ferropaper." ------------------------------------------ Researchers at Purdue University have created a magnetic "ferropaper" that might be used to make low-cost "micromotors" for surgical instruments, tiny tweezers to study cells and miniature speakers. The material is made by impregnating ordinary paper -- even newsprint -- with a mixture of mineral oil and "magnetic nanoparticles" of iron oxide. The nanoparticle-laden paper can then be moved using a magnetic field. ------------------------------------------ The article later mentions that "newspaper and soft tissue paper are especially suitable."

When snow melts, does the purest water melt first?

I know when you make ice cubes, the white cloudy stuff/minerals/solids gets frozen in the center and therefore is the last thing to thaw out back to liquid.

Steam generator for a home-made steam room

I love steam rooms. i want to build one out behind our house in the country in thailand. but it has to be low-tech. i'm thinking i'll make a square wall out of cinderblocks, about 4 feet high. then my shower will stick up from that .we don't have running water. we get water pumped from the well into big jars and use a bowl to splash water on ourselves to wash. but i put a submersible pump in the bottom of the jar, rigged up some PVC pipe and i have a shower of sorts. so if i build a 4 foot high square wall, with a doorway, i can pull a thick piece of foam over the top to cover the top, hang a rubber curtain across the doorway opening, and have an enclosed, outdoor room that i can steam up and sweat the gunk out, then stand up, flip off the insulating cover and shower right there. the steam room will go right behind me and the jars in the shower picture- where you can see a little bit of grass growing. but how do i make a steam generator? commercial ones cost way more dollars (baht) than i need to spend. i can use propane from a tank for fire, or wood, or charcoal. the well water is very hard water with a lot of dissolved minerals in it so my steam generator can't be something that will get clogged up with mineral deposits. anybody got any ideas? the steam generator needs to be cheap, home-build-able with local materials, and safe... don't want anything that can blowup, catch fire, or asphyxiate the users.

why are my jalapeno chillis turning purple?

Hi, I am growing jalapeno's for the first time and something strange is happening, some of the jalapenos are turning deep purple.

Also ive added fertilizer a few times and added some seasol (seaweed extract) recently as well, so there ought to be enough nutrients in the soil. Could the purpling be from sunburn? some jalapenos are only purple on one side, and green on the other, or could it be sun exposure is causing some sides to rapidly ripen, such as what occures to some apple varieties . Does anyone know exactly what causes the purpling to occure, and will it at all have an effect on the outcome of the fruit?

X-Ray Polaroids

Here's a good use of old radioactive material. Use it to expose Polaroid film to create some ghostly images of old items.Why would anyone do this? The author puts it out there pretty clearly:For some time I've been fascinated with the idea of reproducing these types of images in my home lab without great cost and with relative safety. As a collector of radioactive minerals and other ephemera, I decided that I wanted to use naturally radioactive materials as the source for my 'penetrating rays' rather than an amateur electrical x-ray machine setup.Polaroid film is readily available and it develops itself. However, a workable technique needed to be developed. How to expose the film for hours or days without the need for absolute darkness? How would I develop the film reliably after an exposure was made?The answer came from Kevin Clark of the Yahoo group, "GeigerCounterEnthusiasts". It was here that Clark explained his simple, yet reliable, technique for creating inexpensive Polaradiographs.Items you'll need: 1. A Polaroid SX-70, Type 600, or Spectra camera 2. A package of unexposed Type 600 or Spectra Polaroid film 3. One metal cookie tin at least six inches in diameter 4. A few sheets/roll of aluminum foil 5. Radioactive materialThat radioactive material can include:- Old, unused lantern mantles- Salt substitute or certain rock salts (Potassium Chloride)- Vaseline glass (plates, cups, or marbles)- Fiestaware plates and dishes- Welding rods- Old camera lens or vintage prescription eyeglasses (look for yellowed or browned optical glass)- Uranium ores and minerals- Exempt, unlicensed radioactive calibration sources- Radium containing clocks, watch hands, compasses, dials, and gauges- Tritium gunsights and keychain fobsCheck out the site itself for the full story. It's a good read with plenty of information about the history of x-ray photography.via Neatorama

Gelli plate substitute

Hi. there is a new craze sweeping the craft and art community with a mono printing plate called a gelli plate. It's made out of some sort of mineral oil or gel of some sort. (i think). It's a flexible, clear mat with a soft feel and a give to it, a bit like jello. There are plenty of homemade versions using gelatin. which works fine for a while but it soon breaks up or bacteria sets in as gelatin is a food substance. Are there any clever boffin types out there that can make a similiar product that doesn't use gelatin and that has a good shelf life. I first thought of Oogoo but it's not pliable enough. This Gelli plate reminds me of the soft silcone gel that is used for scar healing, but is so expensive for small sheets. here is the link to see what I am after. http://www.gelliarts.com/pages/gelli-printing-plate-demo
