I used a substitue in the flat breads?

I didn't have plain greek yogurt. But figured this to be pretty simular. I had Peach flavored Chobani yogurt. I stole the white yogurt off the top which was not mixed, which measured just a little over 75g but took a little back to make the 75g. ate the remaining amount. Very nice recipe will make this again and again. We made it like a taco hamburger mix, lettuce, tomato,and would of added cheese accept it was frozen. So did with out. Very filling. Eyes were bigger than my stomach. Ha Ha. When I fried them I brushed them lightly on both sides lightly with olive oil. I also sprinkled flour on wax paper added a flat bread and sprinkle with a duster more flour, added another sheet of wax paper and so on. It did stick slightly but nothing to disturb the flat bread. They didn't puff up. I must of went to town frying them. I syran wrapped and foil wrapped the rest for another day. Delicious lunch. Thank you.JoAnn the Troll Lady

Release agent for creating oogoo object with oogoo mold?

Hey all, I have a mold of a webcam which, due to steep undercuts, I made with oogoo.  Worked great! Now I want to make a rubber duplicate off of that.  Only problem is silicone sticks to silicone like crazy! First I tried a sample with cooking oil and also wd-40.  It still stuck.  I heard cooking spray is a no-go since it actually contains silicone.  In fact, they say that's what most cans of mold-release you buy are made out of.  Just cooking spray!  Interesting factoid, but doesn't solve today's problem. A mold-making book I found at the library said something called "spray wax" is what you need.  After searching Amazon and Smooth-on plastics I wasn't able to find any mold release called that, so I just tried grabbing some cheap spray-on car wax from Walmart.  That's either not the same thing, or oogoo is too different from the official casting silicone that the book was talking about. Anyway, I'm about out of clues now.  Anybody got any more tips?

Can diesel be separated from petrol?

​this is a reply to my last question as for some strange reason I can't reply and leave a comment to the thread. ok thanks to those replies,  I am in oz and the reason I've asked is due to free diesel that has been contaminated with petrol being offered to myself. So, given I have free fuel I am prepared to treat, separate, spend some $ on in trying to produce diesel and petrol separate. I have looked at a continuous separation distill unit but I don't know how it works and the safety factor, don't want to make a bomb! Other ideas are leave the diesel out in sun and evaporate petrol(not so good for environment and water getting in diesel) or add oil to mix. Most of the fuel mix is majority petrol and minority diesel, although exact ratios are unknown. I have run my lawn mower on it quite well so given that it is mostly petrol, can I either;1. Add more petrol pure to further dilute the diesel. 2. Add an octane booster to over come the diesel influence. And specific comments and answers appreciated

The Red Book of Westmarch Insider

Ever since I was a young lad (XD) I have wanted to learn whatever I could. How to clean a firearm, how to change the oil in a car, how to sight in a scope, how to string and fire a bow, the list goes on. An item included in that list is how to make a website. So, as many of you may know, I made a website (using Weebly), called The Red Book of Westmarch Insider. I decided to make this forum topic to let you guys know about some of the new stuff on the site. I have a couple of new polls, one Up to Date post, and a rather large Video Series page. I also have the ability to make a forums page, but I chose not to do that, as I was not sure as to: 1) how it would work, 2) whether or not you could post pictures, and 3) if anyone would be interested. I also made this forum topic so that I could let you guys know when I have something new on my site. You don't need to post any comments or anything, this forum topic is just to give you quick links to new posts and stuff on my site. -The Red Book of Westmarch

WD40 The wonder spray, as it can be used for.....

I just finished looking at a post about why not to use WD40 or similar products on you pedal bike chain, and I agree with that, as WD40 t is not a lube, it is a cleaner and nut unsticking liquid. I also have heard of people using it as a drying agent to get water out of hard to reach places. WD40 can be used for other things of course, and I am curious as to how many things people use it for. I have used it as a tool cleaner in the past when I worked underground. One shift I found a 12" crescent wrench in a pile of mud. It was dirty, rusty and generally looked like poo. Interestingly if was the exact color of poo too. First I blasted it with compressed air to get the bulk of the mud and crusty rust off. Then I soaked it down with a can of WD40, and blasted it with air again. The improvement in appearance was amazing. The wrench now looked quite good. I repeated this 2 more times. I then oiled it and added it too my tool belt. That wench was better than the one I had on my belt. I used that technique on numerous tools and dirty machine parts after that. Next person with a novel use for WD40 please, and thank you. Zipperboy aka adventureboy7 aka Phil

Tesla Coil Capacitor help

I have just started building my first tesla coil. I am fairly experienced with electrical stuff and high voltage but I can't seem to get past building a homemade capacitor that will work. My first attempt I built eight Leyden jars in parallel that were constructed from glass canning jars and metal tape. Next I tried lining a 5-gallon bucket inside out with aluminum foil. Lastly I tried assembled a rolled capacitor with aluminum foil as the plates and wax paper as the dielectric (about 10 square feet). All of these have failed in a similar fashion; I hook them into the circuit and the spark gap wont fire. There is no arcing however the bucket and jar constructions made a faint noise similar to a capacitor charging. I have seen instructables and videos with only three or four Leyden jars in parallel and the spark gap is firing. I don't know whether the homemade ones just don’t have enough capacitance or if it is something else. If anybody has any input on the problem please help. P.S. I am using a 14kv 35ma 60hz oil burner ignition to power the coil below is a diagram of the circuit configuration

In addition I see the future and now know the stock market BEFORE it happens!

""I couldn't believe a cable could make so much difference, so I connected a cable tester to it and saw that it rendered the 0s and 1s perfectly. I'm even getting some 2s and 3s!!!""Each one of these cables is blessed in the blood of a dead pope."There are, however, a refreshing number of people saying "I'll never buy anything from Denon ever again".

Belarus Tractors-cold weather starting information?

Thank you for taking my question.  I purchased a Belarus tractor model 525 (65 hp. 4wd) new in 1990.  Although the tractor came equipped with glow plugs, they burned out shortly after I purchased the tractor.  I replaced the glow plugs again and they also didn't last long.  I then installed a block heater which heats the water and also a small heater from Wolverine company which actually glues on externally to the bottom of the oil pan.  Now although these products help somewhat, I was wondering if any of my good Instructable friends have had similar problems with these types of tractors and how they eliminated the problem.  The two heater items while they help, require several hours if not overnight to work.  Other than the cold weather starting problem this has been a good solid tractor.  In closing, I know these tractors are made in Belarus/Russia where the temps are far more severe than here in Southeast Missouri so I know there must be a solution.  One last thought, cold weather for these tractors is defined as any temp. below 60 degrees F.  Thanks, Debra Kay

Innovative solar powered radiator - will it work?

Ok, so i live in a rented flat (apartment) in London UK. Its a small flat but its old and doesn't have a gas heating system so i'm stuck using expensive electricity especially as the windows are single glazed and winter is on the way! Brrrrr! I desperately need a cheap and effective heatsource Now I know solar water heaters can be suprisingly effective even in the cold and that got me thinking. I have a south facing garden. Couldn't I use the sun to heat the flat? Specifically, I was thinking, can I use a solar water heater to heat an insulated water tank, then use the tank to heat a radiator after dark? (See diagram below) Bear in mind in temperature during the day at the moment is 11 degrees. Will enough heat be generated to make the system viable? I.e. will the water heat the tank hot enough during the day to keep the room warmish for a evening? Other pressing questions: Do i need a commercial panel or will an instructables model work? Oil filled radiator or water filled? Will it auto-siphon or will i need a pump? cheers a million guys and gals!!!

Updated information on woodblock printmaking

Just read through the woodblock printmaking advice. The article does not give the artist's name but there are a few bits that I would like to add. First: there is an oil based ink made from soy that is non-toxic and easy to work and clean up. T.N. Lawrence and a London based printmaking supply company both sell Akua inks. This is wonderful ink with terrific colours in addition to the blacks. Second: buy the best carving tools that you can afford and keep them sharp. A dull blade will cause all kinds of carving problems. Third, instead of buying great hunks of wood at enormous costs, think about buying a decent plywood (1/2" at least to minimize warping). I like to use poplar but ask your local lumber supplier for advice. Soft wood is easier to carve but harder wood gives a finer line. Fourth: use the thin Japanese papers for the best results. Ask for sumi-e (ink painting) paper. One can buy it in rolls or sheets. Fifth: instead of covering a book with a towel and risking the wood moving, use a bench hook. Cheap to buy and cheaper to make you own. Essentially it is three pieces of wood screwed together.  Google the word or just ask at your local art store. Check the image. Sixth: have fun but be aware that this art form can be habit forming.

How do I replace worn out front struts on a 98 Honda Accord; and how much would it cost me? Answered

How do I replace worn out front MacPherson struts on a 98 Honda Accord; and how much would it cost me?Note; it seems I can use pre-assembled Monroe "Quick Struts"; would I still need the spring clamps if I us a quick-strut? I've heard this could be potentially dangerous; how would I minimize danger? Other things; would I need to bleed the brakes after? ( I assume yes) What's the basic idea behind that? I would need an alignment I'm going to assume, from what I hear, I can't do that at home - but can I get it "semi-right" to drive it to the shop? I have most of the tools available aside from a torque wrench. If I get a Monroe quick-strut, what other things would I replace? Any bushings/bearings/stuff that would be good to change at the same time? Personal experience, Changing oil/fixing radiator leaks/doing basic maintenance on cars (brake pads/rotors, spark plugs/ distributor cap etc) The easy stuff basically. Honda quoted me at 800, and independent quoted me at 600. I can buy those quick-struts for 180 a pop.

best way to test an alternator?

We are having some electrical problems with a john deere tractor, and received an error codes 61f, 018, 023, 026, 049, and 051. These error codes are not cleared when the problem goes away, and from memory, the first few meant low fluids at some point, and one of the later ones is indicating the output of the alternator is outside of normal operating range. The problems experienced: * The tractor would start, and "lunge" forward but never actually go any go further than 4 feet. * reverse does absolutely nothing. * hydraulics work fine * Engine would start in any gear, when it should only start in neutral. * Replaced a few dead fuses and a missing relay but these did not change anything important. * oil / hydraulic fluid was very low, we fixed that. * this lunging behavior was intermittent before, only requiring some wiggling of the gear shift. * requires jumping in order to get started. Does not always crank fast enough by itself to start on its own. Today, we plan to test the alternator to see what's going on there, It is rated to deliver 115 charging amps to a huge 12V battery. what is the best way to test this with a basic multimeter or some basic around the house parts? I measured the voltage across the battery rise from 12V up to 14V, so it would seem that it's fine, but I'm going to take that with a grain of rice. Is there a better way to measure the alternator?

DIY Plug-In Hybrid Pickup Truck

Hi everyone, For a while, I've had this as my "back-burner" project. I'm trying to really get going on it now. It's an Open Source, DIY, Plug-in Diesel/Electric Hybrid Pickup truck. That's really a mouthful, so I'm just calling it the "SuperTruck" project, until I can come up with a better name. The entire concept is that it is a parallel hybrid, which you can charge from the wall, and it has a diesel engine that can run on diesel, bio-diesel, and possibly veggie oil. Either the engine OR forklift motor will be able to propel the vehicle. (Meaning that it will have a dedicated EV mode.) The driver can manually decide to run it on diesel, electric, or both depending on the driving situation. The mechanicals are relatively simple. It uses a manual transmission (rather than a CVT or planetary gearing.) In theory, this will be a project than any advanced grease monkey will be able to duplicate. I'm not much of a car guy, but I have learned quite a bit working on my electric motorcycle, electric car, and experimenting with running my car as a hybrid. Here's a YouTube playlist of what I've got going so far. For the latest on this project, please visit the page for it on my blog: http://300mpg.org/projects/supertruck/ I'll definately need help on this project, so please tell all your friends about it!

Rebuilding NordicTrack ski machine drive rollers

Many people still buy and use a NordicTrack Ski Machine, although these machines are not as popular as they once were. I have talked to people who say they just plain wore out a ski machine. The part that wears is the one-way clutch inside the drive rollers. NordicTrack makes the one-way clutch sound very mysterious. In reality it is a one-way needle bearing and is available from Amazon or locally from a good bearing shop. The internal diameter of the one-way needle bearing used in my machine (Challenger, similar to a 303) is 5/8 inch. The outer diameter is 7/8 inch. The width of the one-way needle bearing from end to end is 5/8 inch. I originally had hopes of being able to install new one-way needle bearings, myself; but, they together with the bronze sleeve bearings on either side of the one-way needle bearing inside each drive roller are pressed into place. Pressing bearings is not a job for the average home tinkerer but requires a bearing press capable of exerting tons of pressure in a very precise manner. You can often have a local machine shop press the bearings in your machine's drive rollers. Or, you can send them away to Nordic Track Guy and have them rebuilt for about $33 with a one week turnaround. The core of the rollers really does not wear out, but new rollers are available on the Internet from $65 to $95, depending on the vendor. From what I can find, some models used an alternate size. Check to be certain you order the correct rollers, if you choose to replace. One of my drive rollers suddenly began to hiccup. It seemed that the clutch did not always release immediately when I pulled my foot forward. Then I noticed a little mush in the response when I began to bring my foot back on the push stroke. Before you rebuild or replace your rollers, try this: Remove one side of your Ski Machine. See the second photo and check the exploded diagram in your manual. Four nuts and two screws, all plainly visible, need to be removed. Slide the washers and the roller off of the top side. The shaft and flywheel can be wiggled out of the other side without removing anything from that side. Remove the washers and the roller from that side, too. Flush the one-way needle bearing by squirting some penetrating oil, like Liquid Wrench, into the bearing. Work it both ways with your smallest finger. Push a facial tissue into the shaft hole in the roller and sop away the penetrating oil and any metallic dust it lifts. Do this several times. Let the rollers air dry. A little lubrication is good. People who comment on lubrication for one-way needle bearings use Tri-Flo (I am not familiar with it.) or they use a little ATF transmission fluid. You want enough to lubricate, but not so much that the bearings slip. (But, see the comments below where the oil impregnated bronze sleeve bearings are supposed to supply enough lubrication for the needle bearings.) Put the rollers back in place on the shaft. Check to be certain they grab on the rearward stroke and release on the forward stroke. Reassemble the machine. Do not forget the washers between the roller and the side board. My machine works again as it should. The day will likely come when this simple fix does not help, and I will need to rebuild or replace the rollers then. But, for now, my rollers have a new lease on life. What follows is for your information. The first photo is of a portion of the back cover of the manual that came with my machine. It shows a cutaway image of the drive roller. The black printing is mine. Notice the three cylinders inside the drive roller. The outer two are bronze sleeve bearings. The center one looks like a roller bearing, but is a one-way needle bearing. A one-way needle bearing is essentially a roller bearing, but the rollers are able to move forward and backward a little in their cage. There is a wedge shape for the axle of each roller that causes the rollers to bind between the bearing cage and the shaft when the rotation is in one direction, but they are free in the other direction. Here is a description of how they work with graphics. This link is for an Instructable about a number of modifications I made to our NordicTrack ski machine, including how it can be stored vertically in a closet. If you do not have a digital monitor for your skier, or need to replace one, here is an Instructable on how to make your own from a digital bicycle speedometer.  Check NordicParts for any parts you need, also Nordic Fitness Ski Machines. Danny at Nordic Fitness Ski Machines has some very nice new rollers for sale.

Best practical way of making biochar for soil improvement on commercial scale?

I need help to build a cost effective biochar retort that will produce at least 500 kg biochar/day to use for soil improvement on my dairy farm. It must also be moveable to move to new sites. I've got access to a lot of forestry waste all over the district. Here is my initial idea: From 3mm sheet metal manufacture cylinders (drums of say 200 lt) one bigger than the other so that one fits into the other with a 100 mm play all round. Bigger cylinder has a lid with a chimney on top and close ended at the bottom with air inlet holes around the base and completely isolated with fire proof material. Smaller cylinder (that goes inside) is open ended and stand on bigger cylinder baseplate with airtight lid that gets closed after filling with wood chips. It has 50mm outlet at the top that connects to a metal pipe (coming through the side of the outer cylinder) that leads woodgas to the bottom of the next retort and maybe have a drain to catch bio oil. The idea being that I can duplicate the retorts to increase production using woodgas from the previous to pyrolize the next. I then only have to burn wood in the first retort to get the process started. Please suggest improvements, or complete new more viable system. What can I use for isolation material? Can I collect other products off the woodgas instead of pyrolising the next batch?  What other byproducts might be valuable?

What would happen if the Internet were to fall?

With all the terrorism stuff going on, I've always wandered what would be next.Ever since 9/11, I always asked myself were they would strike next, because they certainly did not intend to stop there.My guesses have been that they would probably strike at either:1) Elections - Either at the thing were they welcome the new president (sorry don't know much bout U.S. polimatics)2) Beijing Olympics - Its an important event3) Internet:I came to realize that one of the worst things that they could do was attack the internet. I figured that one of these methods could be used:Multiple malware methods. They could attack individual computers with wormsSomehow attacking diffrent countries methods of connection, being either telephone companies or whatever other methods they use (like those China underwater tube things)* But my best guess would be that they would strike important service providing companies. They would destroy the companies methods (satellites, cable mainframe stuff etc...)I would like this forum to have the porpose of disscussing terrorism issues and future issues like oil and so on.

How can i keep my MOT from drawing to many amps and why dose it heat up so much when I draw arcs?

I just made a 3 phase MOT power supply and it's fun to play with (while being safe) but every time I use both phases it trips the breaker after only 2 arcs, sometimes it trips just from plugin it in, I am using a PFC cap on the mains side as well as a long extension cord, I have one of the transformers ballasted, and one of them has 3 MOC's in series on its output, the breaker can handle one of them just fine...for a little while. Is there any thing else I can do besides buying a bigger breaker switch? I'd say mine is 20A but i dont know for sure.  Every time I draw arcs from my MOT it heats up really fast really hot, I am using the same setup as above , the only thing I can think of is to submerge it in oil but I dont want to do that because I'll want to make changes to it. What makes it different from a welding transformer in that they are made to draw arcs from but when you draw an arc from a MOT its a direct short and will eventually destroy the transformer?

More questions about an office shredder than you might expect :)

EDIT: I ruined it so I will not be fixing it. But I'm sure this gets typed into Google a lot so if you reply it will help others... I recently received one of those big (ish) office paper shredders from a company of a relative of mine to take apart (they know me... :) because it wasn't working like it was supposed to. After having the idea of fixing and selling it, I read online and figured out that the shredder had never been oiled, so I did that. But the shredder (motor) keeps heating up, like A TON compared to the 12-15 sheets it's supposed to handle. I can shred maybe 4 sheets at a time maybe 20 in total before it shuts down in the middle of the operation. I think this might be for overheating protection. Does anyone know what would make the motor heat up so much? Maybe paper dust got into the motor/bearings and makes it work extra hard? And it's not like I can turn it by hand because of these gears. I think it's a brushless motor but it's hard to tell because it's very compact inside. I do know that after it had shut down, I stopped working on it for other reasons, but after two whole hours I came back to work on it and was shocked to find out the motor was slightly warm! Anyone know? I can't find any more info on Google. Thanks!

Anyone savvy with Air Electrodes??? Thanks! =)

I'm posting this after having googled, of course...I work with DIY fuel cells using off the wall fuels. By far, the most expensive component of my FCs is the Air Electrode which I purchase from Electric Fuel Ltd. in Israel. The material was invented in 2008 (as far as I know) and EF were the ones who bought the patent (according to the inventor himself...sorry but his name eludes me). Anyhow, I was wondering if anyone knows how to make good air electrodes. Something that would give me at least a vold in reference to the SHE (V=0) and a current density of up to a few hundred mA/aq cm...The stuff is basically this, from the electrolyte side to the air side: Separator paper, Carbon powder with Manganese or Cobalt catalyst mixed in (and a binder of some sort, I suppose), a Nickel mesh (current collector) and a bit more Carbon+catalyst then a microporous Teflon(r) sheet (permeable to gases but not to liquids). I cant find nickel mesh where I live but the other stuff I could get--the Teflon(r) being replaceable with oil paper??? Any help would be greatly appreciated. N.B: I am Not trying to infringe on a patent, just trying to make some "homebrew" air electrodes for R&D since I am still (steam comes out of ears) self-funded and low on funding...lol. Thanks a lot!!! =)

Car became unresponsible while driving? Brakes unresponsible, motor on, but powerless, few dashboard lights on.

Hi. I own a Hyundai i10 2013. The problem had happened twice, seems to be under the same conditions. I was driving in a decent highway, in neutral speed. Suddenly, the lights: oil, brake, sterring and alternator on the dashboard got on. The engine was working but if I tried to accelerate it did seems that it loose all power, brakes were unresponsible, like when the motor is off and you try to break. My only way to brake was the handbrake. Sterring (don't remember well... due panic!) was working normally. I did power off the car once and the problem continue, power back off and on and everything came back on normally. Second time, same thing happened, this time I was not in panic, I was able to see the dashboard again and the same lights were on. Motor on but without power. Brakes not working, only hand brake. This time, the problem disappeared without power off/on the car. difference in time was around couple of months between failures. I did connect a scanner to the car's computer and ran diagnostics many times, no luck, no errors. I think I must do this while the failure! Not sure where start looking. Dealer ussusally finds nothing. No similar cases on the web. I don't want this to happen again, specially if my wife is driving with my childres. Can somebody help?!!!

What equipment is needed to fill an appropriate cylinder with oxygen generated by the electrolysis of water?

Update: I need someone that has experience with gas cylinders to point out potential dangers that would be present by filling this way, We've already discussed water vapor and oil potentially making its way inside. That doesn't sound good to me so I need certainty that its safe or those can be eliminated or reduced to safe levels. Right now I would really like to know what I need so I can refill tanks myself. I'm guessing its a special adapter or replacement valve, but I don't know where to start Original: Would it be possible to fill an appropriate oxygen tank with the right adapters/compression system with the oxygen generated by electrolyzing water and what kind of equipment would be needed? I know for propane you can buy adapters and refill/transfer from one to another, but obviously this is completely different, and I don't know anything about oxygen valves/adapters or compression systems. Yes I know this could potentially be very dangerous and also have no interest in collecting the hydrogen. Just to clarify we are talking about commercial grade tanks, not a 2 liter soda bottle. Also, if possible how high of purity would be expected using optimal electrodes and electrolytes to prevent corrosion and impurities. Any information at all would be very helpful.

Tracing Plastic Water Pipe Underground.

Earlier today, while removing tree stumps, on of my crew struck water. The theme song for the Beverly Hillbillies came up. "when up from the ground came a bubbling crude! ...oil, that is... " except it was water, and we went scrambling to find the water shutoff. Lawn Sprinkler systems usually have plastic pipe a few inches underground.  No metal.   :.   Can't find it with metal detector. Potential Options: AC wires can be tracked through walls by the electromagnetic flux around them. Stud sensors today also have a circuit for AC wiring. Could something like that be used?  Although city water has some minerals in it, does it have enough to conduct electricity well enough for an electric pulse sensor? If the water in the system was temporarily made salty enough for an EM signal to be traced, would it mess up the lawn once you dumped that salty h2o? Whata bout conductivity of a fertilizer mix? Medical scans- barium- mildly radioactive. mmmm.... yeah. right. Chemical sniffers- sniff out those semi-soft pipes? Like dogs sniffing out contraband in the airport... Use water flow to carry a fine wire through the pipe, then track an EM signal in that wire. sonic imaging (or at least detection- like the stud sensor) ground penetrating radar... That's all I can think of.  Every option I can think of has issues. Is there any precedent for something that works in this situation?

My grandparents found a rock at the beach that spontaneously combusted. what is it? Answered

My grandparents were out walking the dog before sunrise, and noticed an odd rock which felt warm, they left it, it was sitting at the shore line, not fizzling or bubbling, it was low tide,so it must have been submerged at one point within the last 4 hours. Later on their way back, the sun had rose and the rock was now fizzling , when they touched it with their sandal, it burst like a waterballoon of petrol and created a bright thick fire like an oil fire, as if the golf ball sized stone was filled with super heated napalm. My grandparents kicked the small stone which had not melted, into the water and it made a huge explosion which intensified the flames, as if it were sodium. My grandppa kept the stone after it had been burning in the shores wash line for an hour, and took it home. when he got home, he put it into a glass of water and it violently fizzled and sustained a flame momentarily. i checked the so called stone, and it looked like a standard beach pepbble with a tiny bit of quartz attached. What could it have been? that would have passivated in the water and not completely reacted until the inert skin was broken. my grandparents claim it was the sunlight that triggered the exothermic reaction. Anyway, they say the flames werent blidingly bright which possibly rules out alkali metals, plus it was yello which rules out lithium ontop of the meals, as well as the fact that it had previously been under water. does anyone know what it is? like i siad, it looks like standard smoothed beach rock now, its exterior was what burnt.

Is it possible to stick vacuum base vise onto a plastic table.

Hello, everyone, I would like to know if it is possible to make a vacuum base tool (bench vise) to stick to a plastic table? Tables like the folding portable types that are use for outdoors event, hobbies, work bench or any other useful project or jobs. Let me explained; I brought myself a bench vise (from eBay) which is the type in which it is a suction base or cup that suppose to stick onto the table when the lever is push either up or down. My work bench or table is an portable 4 inch folding lifetime (brand) item. After buying and receiving the tool, I tried to stick the vise onto my workbench, but was not able to make it stick at all. I have tried all kinds of methods that I have google. methods like the water method, oil method, tapes and so on, but could not get it to stick at all. This is my very first time I have work with a tool with a suction action to mount the tool to a surface. When purchasing the tool I was under the belief that all suction cups or suction methods works on all kind of surfaces. I did manage to stick the tool onto a glass table, but this is not an alternate solution for me, since the glass table is my dinning table. If anyone has experience this kind or similar problem with a suction device and had solve the problem I would be very grateful for a course of suction basics 101, because if I don't find a solution, it is either buy an new work table to work with the tool (not an option) or abandon the whole idea. Really could use help. Thank you

OFFERED: IBM "Mainframe"

. I have an IBM computer that was used to run a local oil refinery. It has two cabinets (62"H x 36"D x 26"W) that I'm guessing weigh somewhere around 250 pounds each, three terminals (one appears to be "smart"), a few misc pieces of network cable (not Cat5, some kind of coax) and what appears to be a network hub. Approx 10 feet of manuals. . One cabinet is marked: Type 9309 S/N 10-0046692 and contains a 3/4" (maybe 1") mag tape drive (quite a bit of damage to the door, but the transport looks OK) and five PSUs (220VAC in, not sure of the out specs). The rear door is marked "9309 2" . The other cabinet is marked: Type 9309 S/N 10-0074115 and contains a 10" floppy and what appears to be the CPU. . That's everything I know about it. If you can tell me what to look for and where it is on the unit, I'll look for it. . I've never seen it powered up, so I have no idea what, if anything, works. . Located in South Arkansas, US. You must pick up. I will not deliver nor arrange for delivery. It was delivered in a "standard" pickup truck, but the springs were sagging a bit. . Would like to trade for something useful, but will consider free-to-good-home. . Please remember that this thing is huge, heavy, and not much use as a computer (I had dreams of using it for "home control" eg, HVAC, security). If you don't have the resources to come get it, please don't ask questions, 'cuz I've already told you all I know about it.

The best salmon dish youve ever had!

I made up this recipe one day and it became an instant hit with my family and my cheese-a-holic boyfreind! Its super easy but really impressive, great for dinner parties! Definitely not for those on a diet..... :) Serves 6 Rachelles Super Fantastic White Wine Poached Salmon W/Havarti Dill Cream Sauce over Herbed Rice! Sauce: 1 Lb. Harvarti w/Dill (usually sold at Safeway in the specialty cheese case in small ~half lb. blocks) 2 Pints Heavy Cream Salt&Pepper to taste Fish: 6 Skin on Salmon filets 1 Shallot 1 clove garlic 1 Tbs olive oil 1 bottle white wine (I use Chateau St. Michelle Geswurtzraminer) Salt&Pepper to taste Rice: 6 serving of your favorite rice (white brown, wild, minute, doesnt matter, use what you like) 1 tsp basil 1 pinch rosemary 1 pinch rubbed sage 1 tbs butter In a large shallow sauce pan, sweat the shallot and garlic on low heat in the olive oil until the shallot is soft. Salt and pepper to taste. Spread the shallots and garlic evenly across the bottom of the pan and place your fillets on top, skin side down, dont stack them! Pour the wine over the top until its covers about 3/4 of the way up the fish, cover and turn heat up a notch, medium low heat. Now just leave it alone! dont peak, dont poke, dont move your fillets around, just let them sit and cook! Depending on your stove, you may need to bump the heat up to a solid medium heat, you want it simmering, not boiling. Cook until tender 20-30 min. Now start your cream heating. Put it in a large round bottomed sauce pan and place over medium heat, stir occasionally to prevent the bottom burning.  Now start your rice so that by the time your sauce is done, your rice is too, so you can plate up immedietly and you wont have to worry about your sauce setting. Just cook your rice the same as always, only add the sage, rosemary, basil, and butter to the water so that the flavors cook into the rice While your cream is heating shred your havarti. I like to use the cheese grater attachment in my food processor because its super fast and you need top be able to watch your cream too! As soon as your cream is hot (NOT BOILING, JUST HOT) start slowly whisking in your cheese. Whisk constantly while adding about a half cup at a time, keep your heat on medium low while doing this or your sauce will break. It will take a little while to get your sauce smooth, so keep your heat low and just keep whisking until its nice and smooth. Salt and pepper to taste. Plating: Mound your herb rice in the center of your plate, spoon a little bit of the cooking liqiud from the fish over the rice then place your fillet on top. Drizzle a good dose of Your havarti dill sauce over the top and DIG IN!

Cheap and portable >12V >10A PSU for small tesla coil? any good topload sugestions?

I am currently planning a small tesla coil (15 inches high, hopefully 5-12 inch sparks) I would like to make the unit small (desktop size). I decided to build the coil around a ZVS-driven flyback transformer rather than a standard NST or Oil burner transformer due to several advantages the ZVS circuit can offer: battery operation, smaller size, simpler math, no requirement to "match" the capacitance with the transformer, and since I have almost all the parts necessary to build another ZVS driver, why not!? The ZVS driver drive a DC flyback at approximately 15KV, which will then charge a homemade capacitor (I will not invest in a true MMC because it will put stress on the capacitors and connections, not mentioning the price of better quality film capacitors.) I have determined the dielectric breakdown of a few household items (plastic wrap, lids, lunch bags, etc. I assume they are low-density polyethylene) with my ZVS singing arc assumed to be at 8-10KV, and figured one layer of 5x7 inch compressed between 8 layers of plastic wrap gives an approximate capacitance of 0.7nF (sitting flat on a table with a few books to compress the plates closer together) to 1.44nF (after being rolled up very tightly. However, the breakdown voltage of this may be too low. I have yet to test this with my singing arc project)  The Capacitor will be several layers of plastic wrap sandwiched between layers of aluminum foil, which will be cut 3/4 inch shorter on all 4 sides, and after approximately 8-15 layers have been added, the capacitor will be sandwiched between 2 wooden boards with bolts on all 4 sides to permanently compress the capacitor to achieve approximately 10nF +- 5nF. This compression method might even help me fine-tune my tesla coil!  the aluminum plates will be tabbed, so that when they are stacked, the tabs will face opposite directions.  I might even submerge the capacitor in oil and pull a vacuum on it if I feel it will be necessary. However, I have not constructed a HV capacitor before, so I do not know how well this design will work. Does anyone have some experience in this matter? And lastly, my Power supply section to power the project: Has anyone built a ZVS-based tesla coil here? I see them all over youtube, with outputs ranging from millimeters (similar to my slayer exciter project)  to over a foot long! However, they never state what their PSU is rated for, or use 12 Lead Acid batteries, which I feel would be a bit impractical. So my question is: To get the output I desire, how many volts and amps should my power supply be rated for? I am thinking either a 24V 10A Switchmode supply from amazon, with the voltage adjust maxed out, or a 28V 10.8A SMPS, or a cheaper 24V 15A. SMPS. I thought about making a unregulated supply with a large transformer and a high-amperage full-wave bridge rectifier, but this cost more, and I cant be certain on it's quality. Can SMPS be used? can the amperage be below 10A? most importantly, does anyone have good data on current draw @ given voltages @ given # of turns on the inductor and flyback?

What should I do with all this?

Hey everybody, I've been MIA in Ible-land for a long time now. In the meantime, some new stuff has been brewing here. Some totally awsome ibles coming, I promise! Recently I aquired at an auction: -a pallet of computers -printers -a 24" color plotter -a photocopier -a microscope on the end of a long arm with a fiberoptic light What should I do with the pallet of PCs, the photocopier, and the microscope? Obviously the photocopier is the big deal here. Copy machines have a loda of stepper motors (most w/ very high torque), lots of electronics, LEDs, high voltage power supplies, a flourescent lamp, belts, pulleys, encoders, shafts, wheels, feeders, speakers, com. chips, MCUs, RAM (good for advanced robots), lots-o-metal/plastic, and some very awsome/complex mechanisms. Pretty mush everything is in a photocopier. So help me out! maybe I'll use your idea to better mankind and destroy the oil industry! Okay maybe not, but it's a nice thought to imagine every car running on fuel cells. Give me some ideas because too many are running through my head. Things like: -Tesla coils -Rendering farms -laser scanners -CNC machines -static lifters -lamps (yeah, not the best idea) -railguns -large, 4x4 robots -trebuchets -sorting machines -combat robots -lasers -net-enabled robots -high-speed home PCs -extra misc. Also, the toner feeder leaks, that is why the copy machine doesn't work. There is a full toner cartridge though, what do I do with that? Well, give me some Ideas and I greatly appreciate it!

Headlight Restoration on the cheap.

How to restore your dull plastic headlamps to like new, for about $4.00 (if your lamps are dirty on the inside, that is a whole other instructable): Step 1 - Wash the headlamps with common dish soap and allow to dry thoroughly, this will remove the dirt and oils from the lamp. Step 2 - Using regular rubbing compound or silver polish (I used Silvo brand silver polish (about $4.00 a can here in Canada), it may work with copper polish as well) Apply a small amount of compound or polish using a soft cotton cloth (an old t-shirt or sheet cut into manageable size) gently rub the lamp in a circular motion (the amount of pressure is determined by the severity of the dullness, you may need to repeat the procedure more than once) allow the polish or rubbing compound to dry to a haze, usually by the time your done both lamps the first one will be ready to perform the next step. Step 3 - Using a clean dry cotton cloth buff the lens to remove all of the haze, if the lamp still looks dull repeat step 2. Step 4 - Once you are satisfied that the lenses are as polished as they will get, wax both lamps with a high quality auto wax, (a wax containing carnuba is the best) Mother's or Maguires works great. The wax will prevent bugs, dust and dirt from sticking to the lamp and it will retain it's clarity for a long time, if the lamp starts to look dull simply apply a new coat of wax. Step 5 - Stand back and admire your newly restored headlamps - you will be amazed at how much further you can see at night. *The attached photo is of my headlamp on my 1998 Suzuki Esteem - The before picture is from another 1998 Suzuki Esteem, my lamps were almost as bad as the one pictured here.

Soldering Help? Answered

So i recently got a 40 watt weller soldering iron. This is my first soldering iron ever, and i have watched many instructional videos and tips on how to use it. I had a bit of trouble tinning the tip but i got the hang of it. I am using Rosin Core Solder btw. Today i went to go practice my soldering a bit, so i plugged in my soldering iron and waited for it to heat up. Once i heated it up i got a damp sponge and i wiped off the old solder. IIRC i wiped it off and then tryed to tin the tip again, but i saw my tip has turned black. I tried to tin it, but the solder just turned into a ball and rolled off the tip, as if the tip was oil and the solder was water. I tried taking off what i presumed was oxidation by cleaning it with the sponge, mr. cleans magic eraser, and my last resort was a nail filer. MR cleans magic eraser turned the oxidation a grayish blue, but the nail filer was the only thing that took off all the oxidation. (i know that any sort of abrasive thing shouldn't be used, but i was angry and confused). I felt pretty happy, but as soon as i put solder on the tip, the tip immediately turned black and the solder rolled off again, making tinning impossible. I tried re tinning my spare chisel tip too and it wasnt so bad, but the solder just rolled off too. Now all i have left is a tinned "mini chisel" tip that im scared to use because i dont want to mess up what i have left. Is there something im doing wrong? I could really use some help.

Americans avert energy crisis by dieting, study reveals...

Scientists at Cornell University, led by David Pimintel, have performed a meta-study and found that the easiest way for Americans to reduce, and even totally avoid, the looming energy crisis is to go on a diet.The average American consumes about 3747 kcal per day compared to the 2000 to 2500 kcal per day recommended by the US Food and Drug Administration. (This does not include junk food!)Producing those daily calories uses the equivalent to 2000 litres of oil per person each year. That accounts for about 19% of US total energy use.Pimentel estimated 6 kilograms of plant protein are needed to produce 1 kg of high quality animal protein. He calculates that if Americans maintained their 3747 kcals per day, but switched to a vegetarian diet, the fossil fuel energy required to generate that diet would be cut by one third.Pimentel calculates that the equivalent of 2100 kcal go into producing a can of diet soda which contains a maximum of 1 kcal. About 1600 kcal go into producing the aluminium can alone.Other suggested changes to the food production process range from replacing incandescent bulbs with energy-saving fluorescent ones, to using fewer machines, pesticides and fertilisers, and more human power on farms.Reducing the distance that food is transported could also cut energy costs: food travels 2400 km on average to its consumer in the US. This requires 1.4 times the energy actually contained in the food. Producing food locally would cut the energy expended transporting it by half.Implementing all the suggested changes would cut the US food industry's energy bill in half.New Scientist articleNew Scientist Environment Section, special report of energy and fuels

Is oogoo (DIY Silicone Putty) Oven-safe?

Hello! I have a question for people who use oogoo, or generally DIY silicone molding putty made from 100% silicone caulk. I want to cast oogoo molds of lego bionicle masks with polymer clay, but my issue is I need to keep the clay inside the mold in order to prevent any kind of warping, as most of it is spread a little thin (1-2mm thickness) and I don't want to end up warping it even in the slightest. Is oogoo or cured 100% silicone caulk oven-safe as long as it's within the specified temperature range? (I already know most DIY silicone putties aren't food-grade.) The silicone caulk I'm using is GE all purpose silicone I, mixed with corn starch, acrylic paint, and baby oil. The back of the tube says that it should not be used on surfaces that will exceed 400F/205C. The polymer clay I plan on using is cured at 110C, so I don't think it'll be a problem, but I'm worried exposing the silicone caulk mold to high temperatures will cause it to release some harmful chemical compounds. I looked up an MSDS sheet for GE silicone, and they had a generalized one stating exceeding the maximum temperature will cause the release of formaldehyde. Since I plan on baking these in our kitchen oven, I wouldn't want harmful chemicals contaminating a space where we cook our food. Also, if baking isn't an option, since the polymer clay is spread thin, and cures close to 100C, would curing it in boiling water be an option? (That way any water soluble chemicals would remain contained while the clay hardens.) All help is appreciated!

Or, choose to use renewable, responsibly sourced materials with minimal-to-no toxicity such as plant-based PLA plastic instead of oil-based ABS plastics.  If you’re designing something with electronics, consider how much power the circuit consumes, or even how much electricity is needed when it's not in use and in stand-by mode.  Also think through the end-of-life considerations of the product, such as making sure it’s easy to repair, and the individual parts can be reused or eventually recycled down the line. Come up with any project with these factors in mind, and you could win over $1,000 in prizes including a Voltaic Systems OffGrid Solar Backpack, ReadySet Renewable Energy Kit with Solar Panel and LED light, Nokero Solar Light Bulbs and a $500 REI gift certificate. As a special Judges’ Prize, we’re awarding anyone who uses one of Autodesk’s personal design and creativity applications, such as the Autodesk® 123D® 3D modeling apps or the Autodesk®SketchBook® easy-to-use drawing tools. The winner of this prize will also receive over $1,000 in prizes including a Voltaic Systems OffGrid Solar Backpack, ReadySet Renewable Energy Kit with Solar Panel and LED Light, Nokero Solar Light Bulbs and a $500 REI gift certificate. Your project may also become a learning resource to teach kids about sustainable design! For more information on green product design strategies, check out the videos and tutorials on the Sustainability Workshop that cover whole systems and lifecycle thinking, improving a product’s lifetime, lightweighting, and more. Contest is open 4/22 - 6/17.

The real gas guzzler: Car that turns hydrogen into electricity hits the road

Car that turns hydrogen into electricity hits the roadIntroducing the family car that runs on hydrogen and pumps out only pure water from its exhaust pipe.Honda's FCX Clarity is the world's first production hydrogen-powered 'fuel cell' car - with its own onboard power station which creates electricity to drive its motor.It has a range of 280 miles and a top speed of 100mph, yet emits no harmful pollution. And it is about to become the latest 'must-have' accessory for the Hollywood set wanting to show off their green credentials.Just the thing at a time when oil prices are rocketing to record highs. The only drawback? Finding somewhere to fill it up.The FCX is the result of nearly 20 years of research and many prototypes by the Japanese firm.It is being launched first in California where Governor Arnold Schwarzenegger has spearheaded the creation of a chain of hydrogen filling stations - as part of his environmental drive for cleaner cars. The first five customers include movie actress Jamie Lee Curtis. Honda claims the FCX offers three times better fuel efficiency than a traditional, petrol-powered car.The highly explosive lighter-than-air gas - which once kept the ill-fated Hindenburg airship in the air before its fiery end in the 1930s - is kept safely in a pressurised tank in the boot.Honda plans initially to produce about 70 of the eco-cars a year. They are initially available only to lease for around £300 a month including insurance - equivalent to a purchase price of £24,000.But Honda admits that the billions it has spent on research means that the true cost would be more like £1million per car.British motorists will have their first glimpse next month at the British International Motor Show in London's Docklands. Although there are price issues, its great to see there's development of this idea. I hope this sort of car is available for the "common man" at a "common price" soon.......

Do you have an appreciation of the ocean and are all about open-source? I'm looking for people to share ideas with me.

Hi, I’m working on a project about making society more aware of the ocean. This project is my master graduation project. The envisioned project will involve the open-source community; this is why I am looking for people to talk to on this matter and to share ideas. If you are already convinced, please send me a message. I promise you, I will not spam you to death. I am looking for people that have an appreciation or connection with the ocean and are all about DIY and open-source and are willing to share ideas with me. Some more info on the project: As I see it we (society) are very connected to the ocean, most of the everyday objects are in someway shipped across the ocean. Eventually ending up as plastic bits in the ocean. Even before the Industrial Age we’ve been exploring the world with ships on the ocean.  We’ve been shipping diseases, slaves, religion and tobacco around the world in small wooden ships. The ocean also acts as the source of life, in other words, all of the creatures on land came from the ocean. The ocean provides us also with an import source of protein to feed the world; fish. The ocean houses tiny creatures called plankton that are critical for the planet. Most people don’t realize that a mouthful of seawater contains millions of bacterial cells, hundreds of thousands of phytoplankton and tens of thousands of zooplankton. Although we have this strong connection with the ocean we have yet to explore 90% of it. In our ordinary lives we’ve been so disconnected of the environment around us, the only thing the majority of people see are the beaches, the endless blue, until of course, some oilrig blows up and washes oil up on the shore. The project I am working on sees opportunity in creating a connection with the ocean somehow. This is not an easy challenge, I cannot do this alone, I am asking a community of people that think outside the box, are hands-on and are compassioned about what they do for help. Message me if you would like to be involved!

Do you have what it takes for the Design and Build challenge?

I have been researching and think a lot about mobile structures specifically campers that are light weight and highly efficient. After spending a substantial amount of time looking around to see what designs are out there I have concluded that there isn't much. This fact bothers me for a few reasons but mostly because I have a vested interests in this topic. Come march I plan to begin living in a small camper while traveling around the country for several months the only catch is I am going to build it. So my question is what idea's can you all come up with that fit within these guidelines. 1- It must be relatively comfortable for two to live in but cannot exceed 60 sq ft. 2- It must include a toilet, shower and sink as well as a space for a camping stove 3- It must be insulated and have windows for ventilation and natural light 4- It must have storage space 5- The interior must be no less than 6ft tall so that I can stand up straight while the exterior cannot exceed 9ft. 6- It must have a water tank but I do not want any electricity / plumbing and I do not intend on carrying water while in transit. As of now that’s pretty much it for requirements. I should mention that this structure is going to be towed by a ‘05 Honda civic 4 cylinder automatic so the entire unit cannot exceed 1100 lbs trailer included. I don’t wish to destroy this vehicle by towing a camper 5,000 miles around the country but I do plan to add an extra transmission oil reservoir for cooling purposes. I hope some of you find this of interest and have some ideas to share with me. I have some thoughts of how I can make this sucker but I wanted to put my thoughts out and see what someone else comes up with. Thanks and I hope you create something beautiful and functional. Sincerely, C
