Hi all, I found this contraption today at the tip and was wondering if anyone knew what it might be? It has been hand-made and looks like it measures something but I can't work out what. It has a micro amperage meter, an LED, a bunch of coils which look like they are from a heater, and also a analogue clock on top with no hands. Oh and it also has some small glass tubes on top which look like micro movement switches. I thought it might be used to measure lightening or some other environmental effect. Maybe earthquakes? any ideas?

My sister brought me home this part tonight from tech crew at school, she says she thinks it came from a fire alarm but were not sure. There are 2 lightbulb sockets and engraved on the metal it says "75W -125 v". Out of the back there are 6 wires, 1 red 1 black 2 white that are going into the large thing in the middle, and 1 black and 1 white coming out of the empty socket. the 2 sockets are also wired together. What is this part? is it simply a power supply with 2 light bulbs? The label says "Lithonia emergency systems on it" "input : 277 at 60hz (wht and black) output:120v 21.6VA (wht and red).

For a little while now, I have been questioning one thing: "Why are there so many new Pro Members that never even do anything on Instructables?" When you go on the home page, at the right side directly above the contests, you will see that the website shows new Pro Members. The odd bit about it is that when you click on some of their profiles, you will see that most of them haven't done anything on Instructables at all. Wouldn't one of them at least have made a comment, or asked a question? I'm now wondering if the owners of Instructables are making Instructables Pro Members on purpose, trying to convince the others that if so many people already went Pro, maybe they should too. If this is true, they wouldn't lose money, because if they are making the "Fake Members", their money goes right back to them. Leave a comment on what you think, or if you have an answer, please tell us all.

Filled some balloons w co2 from dry ice in a soda bottle. As expected, they act like a lens, a magnifier of sound. No mystery there. Just as a dense glass refracts light, the denser gas refracts sound. The mystery is why balloons filled with co2 leak down faster than identical balloons filled by mouth. Yes, there is some co2 in my exhaled breath, but it is mostly n2, and o2. I would hav expected the n2 and o2 to leak out more quickly, being smaller molecules. So whatzup wit dat?

I'm trying to solve a mystery with an old camera of mine(a kidak cx 7330). It showed a low battery indicator with a fresh set of batteries, as well as some older ones-so i assumed it was broken. Once i had it replaced (which was overdue anyway, its like, 5 years old), i popped in a set of rechargables which i got with the new camera, and it worked. i tried with another, not so fresh pair of energizers ... and it worked too. (all batteries are AA- i prefer cameras that use em, since they arn't toyishly small) Having gotten myself confused, i checked the voltages on all 3 sets of batteries. The fresh set was manganese, and 1.7v. The rechargables (nimh) were 1.4V and the not so fresh pair of energizers(alkaline) was 1.6 v and both worked. I'm wondering (other than what the hell is going on), if electronics have some kinda overvoltage protection, and if that was what was triggering off the issues, and if i ran down the manganese batteries to 1.6v or below, i could use them - that way i'd just use em for something high drain, and switch to them once its done.

While harvesting parts from a tiny refrigerator, I found something that I don't understand. There was a heat sink about 6 inches square on the back with a 12v fan attached. Underneath this arrangement was a smaller heat sink about 3 inches square and sandwiched between the two was an aluminum block, also 3 inches square and about 1/2 inch thick. Between the block and the large unit is what appears to be a ceramic tile about 2 inches square, seperated from the larger sink with a thin layer of white foam. This tile is glued very securely to the back of the larger heat sink. What puzzles me are the two wires running from a PCB to the ceramic tile. They disappear into the foam but I can't tell what they connect to. A heat sensor that is attached to the large sink, perhaps? There was a twist knob inside the unit that allowed you to adjust temperature from Min to Max. I don't want to pry off the tile just yet in case this might be something useful in its current condition. This refrigerator is probably more of an ice chest than anything, else. There are no coils on the back and no compressor. The only motor is what drove the fan. There is a drip pan on the back and what looks like a plastic hose connection but I don't know if this tube let water in or out. The whole refrigerator is only about 2 feet cubed. It was powered by a standard grounded AC cord. How did this thing cool? And what do those mysterious wires under the ceramic tile serve?

I'm in 8th grade and I have to write a mystery, please leave feedback and suggestions. I just want to make sure that this mystery would make sense to someone else, someone else who didn't write it. A rich man laid dead in his room with a will next to his body. He had many cuts and died from blood loss. As the police asses the situation they notice a knife next to him, the police thought suicide. Then they noticed a bloody will next to him, on the will it said that he would leave everything he owns to his butler. The inspector, inspector Higgins, found that it was odd the late Mr. Light left nothing to his wife, Mrs. Light who was sobbing next to the inspector. âWhere were you when your husband was murdered?â asked inspector Higgins. âI was out shopping, I was getting him a Christmas gift.â Answered Mrs. Light âDo you have proof of this?â âWhy yes, yes I do! Hereâs a receipt from Kronix, the fancy watch store.â âHmmmm. Here on the receipt you bought it about an hour ago, there would be have plenty of time for you to have commit this murder.â âHow dare you say such a thing!?! I loved my husband, and I can explain about the time frame, Kronix is about an hour away, so it takes me time to get here!â âOk, ok, ok, but what about this butler of yours, where is he?â âI donât know, he should be in the house.â The inspector and the police searched the house. The inspector came to a closet door and tried to open it, but it only opened an inch. âOfficer, please help me open this door,â said the inspector. After much pushing they got the door open enough so that the slim inspector could slip into the room where he saw a shocking sight. âThe butlerâs in here, he was laying next to the door, and he appears to be dead from cuts.â Paramedics came rushing in . âHeâs not dead, heâs merely unconscious, and we must get him to a hospital. A day later when the butler made enough of a recovery to talk. âMrs. Light killed Mr. Light, she started slashing at me, but then I ran into the closet, which was foolish. She attacked me in there and I passed out, she must have thought I was dead.â Whispered the butler. âYouâre under arrest for the murder of Mr. Light.â Announced the inspector towards the butler. How did he know the butler killed Mr. Light? The solution: When Inspector Higgins found the butler he was laying next to the door. According to the butlerâs story he was being attacked in the closet, which means the murder would have to leave, which would have been impossible because the butlerâs body kept the door from opening.

Hello K'nexers, just wanted tell you about 3 new subscribers and basically I got a new one on the 18th and 25th January and then on the 1st February which were all Sundays so basically I was getting a new subscriber every Sunday for three weeks and then it just stop although I still do get them which is good a thing. From my POV it felt like a winning streak or it was just down to luck but I'm not quite sure myself since it was just very weird thing to happen. Would be interested to hear you thoughts and opinions.

Even before the repulsine saw some attention during WW2 there were sightings of what we know call the classic UFO shape.Be it in Austria, Poland or other places in Europe, people reported weird disk like thing with a dome flying around.What leaked in images and documents after the war shoed that the repulsine looked basically identical to what people saw as a UFO in the sky over big parts of Europe.Then again, the repulsine appearently never made it a usable stage, same for most jet fighters at the time and still they flew around...If we now just take it for granted that actual test flights really happened back then you might wonder why we did not see any after the war anymore.For most critics it is a simple sign of facts and "confirms" that the replusine might have been a nice idea but never anything that really left the ground.As said, I often like to dig deeper and in this case the digging took far more years than what I planned on.I can not provide any solid proof for the following but I am sure even a sceptic will come to similar conclusions after reading it.Try to find some "eye witness" reports from people who saw the so called "Roswell UFO".Yes the one that made Area51 so secret and famous...Reports can be boiled down to some essential features of the hull, for those who saw it proof that it is alien.Three distinct round shpes on the underside, like you add the bottom of an egg to a round disk.Said disc of the bottom was also shaped like a wing, or the flying disk toys our kids like to play with.On the other side the shape grew up like a half shphere with an added cone or round top on it.On these area they claimed to have see engine outlets or similar and appearently the top cone was spinning in another direction than the rest of the UFO.Now I am no expert for Roswell but if I leave area and time out then I could have been fooled to think these people discribed exactly the same thing people saw a few year eariel flying over Europe.The Roswell UFO was not from another world, just stolen from the looser of a really bad war.What was seen was a working Repulsine, be it an original or something the US created from the 5 prototypes that disappeared after the war.Ha, ha, good one, then why don't we saw them flying after this anymore?Well, for starters it was a testflight gone wrong.Presumable it was planned to be limited to Area51 but the pilot lost control.Considering the Nazies appearently did their best to kill everyone involved in the project before the aliies arrived it is no big surprise.What that test flight would have shown is the impossible manouvers people already witnessed over Europe.90° or more turns at full speed instead of making a turn like a plane, sudden changes in alitude as well as accelleration on a level that makes even modern rockets blush.And if it really was the first bigger testflight they did it explains the big secrecy about the Roswell incident and what followed and created Area51 as we knew it.A "weapon" capable of these things would mean total dominance and options to impove planes and more.So why did they not even do that - or did they?The repulsine was created based on what we call today fringe- or pseudo- sience.If there is only one peroson, or a few that can even understand the claimed working principles that it can't be science as we know it.So, lets take a look what things were already heavily used in the repulsine that "we" claim to have developed or discovered decades later.Coanda effect.When air travels over a surface then it will follow the surface.You can try this with paper strips and blowing on them as well as a stream of water and some shaped objects.Long known but never found any real use until the military picked it up.For example air inlets were then developed to utilise the coanda effect.Remember how a lot of them these days look like a ducted fan housing?The round and slightly conical shape of the inlet will actually act like an airfoil and provide lift - of pulls forward in the direction of the air flow direction of the engine.I supercars we use it to create more downforce and better aerodynamics.Venturi effect.Again a very old one but funny enough also a major factor to make a jet engine work.Tesla turbine.In the Repulsine the rotating copper disks acted like a huge Tesla turbine by using a similar effect.The space between the disks got smaller and smaller towards the outer perimiter.Due to the fast rotation the molecules were accelerated and this created a partial vacuum.We use these principles today for specail vacuum pumps but also in military applications.Harmonics.Without harmonics and resonance the Repulsine would have been impossible.And at a first glance it seems we never made any use from that bit of the machine.Then why do we design exhaust systems in such a way than already the extractors ensure a pump like action and controlled backflow?The sound a good exhaust makes is also based on using the harmonics created by the explosions in the cylinders and expanding gasses.We learned that it is far more efficient to use harmonics and resonance in an exhaust system from somehwere ;)Plasma.The repulsine was said to have emitted a bright glow during certain movements or speeds.To create plasma we need a lot of energy, not so much however if the plasma is a by-product anyways.We learned that a high enough voltage differencial in a vacuum can create a nice plasma arc.From there things like analog TV monitors were created.But we never made anything that creates plasma for any use in an atmosphere.Well, unless you start to check supersonic rocket engines and other things.The working principle is very, very close here in some applications like the ramjet.Vortex energy.Today we see all vortex energy stuff as a free energy scam or at best a waste of time.But from the inlet to the outlet the entire Repulsine utilised what we now know as vortex energy, vortex math and so on.The air is twisted and spun around so many times that it is hard to keep track - but it always happened in a harmonic and resonant fashion.In some way this is implepemented in very expensive cars to keep the ventilation system almost silent even at full power.If you ever take an expensive car apart you might wonder why the air system is not as smooth and straight as you would have expected to get this silence ;)There is more but the list would become too long ;)So, if the repulsine was really that great then why was it taken apart to only utilise fractions of it in other things?If you have something really great that combines a lot of things then no one would suspect if you "developed or discovered" some of it in other projects.And to give you a very bad comparison for the other way around:If you know how to combine a petrol engine with some long blades then you could fly!I know, we did that already but you get the point.I can give you a motor and blades but that would not mean you could build a plane or even helicopter!At that time and still today something like a Repulsine would upset the "balance of power".If claims are correct then the engines of the repulsine were only required to provide the enrgy for directional changes or speed but it flew on "free energy" as the main engine system.In lame words like a jumbo jet that only needs a small engine for the hydraulics and electricity...Another big problem is the replication even if you would have a complete and working model to disect.You see most parts were brazed or welded as screw or rivets would have been problematic in certain areas.Other parts like the Kudo horn like intake systems would even today pose a challenge if you want to replicate them 100% correct.And if your understanding of science and physics greatly differs from those who originally created the thing...If your understanding tells you a dice has 6 sides (we all know that) but in my understanding it would have 16 then you would never understand how my dice rolls ;)Bringing true free energy of any form into this world is only allowed if someone can still make good money from it.Just check solar cells and wind generators - we all can have them but our providers make sure they have enough of them as well ;)Will we ever see a fully working Repulsine again?Of course !Some people like old cars, some collect old planes or old machines and tools.A great project for people in the right trades is always to build thier own little steam engine.So to say as a reminder of how it all started.Same will happen with the Repulsine as the first really utilised free energy machine the world had.The war and killings were not what really scared the world.This happened and will happen over and over again to various extends.Really scary was once certain people realised what might happen if over there the war would end with a victory and people would have time to develop for peaceful things instead.Without the war or this idiot Hitler a peaceful war would have taken over the world by storm.Those making sure we know nothing else but paying for our fuel and energy would have lost their monoply.Times change though...We destroyed our world with our needs for fossil fuels and electricity.What is left we destroy by chopping it down, digging it out or just by building new estates on prime farm land.People are now more desperate then ever to find ways to reduce their energy bills or enviromental impact.Otherwise Google wouldn't make billions on all the fake free energy videos out there.But what would it take to recreate the Repulsine?The person able to come up with the understanding of at least attempting to build one again would need to have certain qualifications and titles.He or she would hold a Nodel price for completing some of our known laws of physics or for finding some of the still missing ones.It would be a quite hard to understand and like person too, maybe even highly autistic.The person would also have an addiction like need to complete things, add the missing bits.And of course a totallydifferent understanding on how nature and the universe work.David T. from England is such a person, or at least the closest mankind can offer so far.He can see math in his head as shapes and images.Complex math problems appear to him like developing landscapes in high detail.He even learned to speak icelandic fluently within 7 days!!Imagine such a person would develop an interest in the old pioneers like Schuberger, Newman, Tesla and so on?Where we normal people fail to see any relevance or connection a guy like David would be able to literally see how all these inventions and ideas connect.He would be able to SEE the math behind it!Knowing how something was supposed to work and combining what is known through patents, drawing, videos or reports would enable such a person to make conclusions.For example where we might just see a nice pattern when we throw a stone into an undsturbed lake such a person would also already know and see the corresponding math the created the waves and why they were created exactly like this.Assuming David has no real interest in such things, then is it possible others already try?Sadly yes and even worse they do it with kids.Learning methods that are different can bring great results.For example while we use a calculator for big numbers some kids attend really strict and performance based classes to do this with an ancient abacus!After years of hard and often painful training they are able to it with a small abacus that only has a single row of discs.Shortly after they graduate to a virtual abacus - they only twitch their fingers in the same motions they would use on the real thing, but the disks and rods are all just visualised in their heads.That however is all meant as an improvement and the kids do it because they want to and not because they are forced to.Like learning to be a chess champion before even being old enough to work...In china however we have a very selective education program.Kids are not just trained slightly different to our kids but also closely monitored on their progress.As soon as one stands out for some skill it is subject to examination.Being well above average here means it is an opportunity for the kid and the parents - on paper at least.We in the western world would see it as a viscious circle though.Over the years china developed not only a better understanding of how these special kids brains actuall do their things but also how to create tests for this purpose.What looks like impossible or nonsense to most kids will trigger a scecific response and understand in those that are special.We would create something that allows parents to know early on where the kid has really good skills and what activities should be promoted.In china though the parents receive a nicer flat or some additional income while kids are send to a far away school.Again we would refer to such a school more as a boot camp.Discipline is at least on military levels, same is the punishment system.In most cases families are not reunited for many years, phone or even video calls only happen in the rare times when western TV crews are allowed a sneak peak.I just say: If a kid would see the parents often enough then it would not only know what to talk about but also be happy to talk to them - this however you won't see.It is like they talk to some distant uncle or such.What is really scary though is how these kids are trained to see their purpose and how important it is to be the best in what they do.Imagine you lost your kid at an early age and the only thing you got over the year was letters from the government saying how well it is doing and that you can be proud of it.Then it graduates and you are not even allowed to be there on that day...After that the kid is gone for good, you get a new flat and your proud kid supports you with some nice extra income.You don't get to know where it is working, what it is doing or if it might just be attending some university.By any standards these graduated kids can be seen as a great number of genius young people.Math, music, languages, science, you name it and they will have the experts aged below 20 for it.But what do they do once school is finnished and life starts?So far no reporter or family was able to figure it out.Means they don't appear in some high profile company, they don't start a successful business or teach at any public or private school.I leave it up to your imagination where thausands of kids find secret employment once they graduated....If, at least in theory we could be able to understand all these old technologies then why don't we at least try?Everyone has a goal, some desire a happy family and nice house, other need fame or just money to be happy.With that comes greed.You might have a really nice car but that does not mean you would give to some neighbour for a trip.Even if it just a nice rose garden, you might not want to share the views with anyone.This is true on all levels and we created a term for it "Need to know basis".If you just operate a press in a factory then you don't need to know when or what the next job is that comes for your press.You will know when it arrives and can check the documents attached.You don't need to know that your council is expanding and it is only seen as a courtesy to let you know on some notice board or in the local newspaper.And even our government does the same.What we do from the first days of our new baby we do on all other levels in the same way.What the baby does not need to know we won't tell or show.But we provide all the littly anklebiter needs to develop and be happy.Changing nappies, feeding, proving comfort when sick or having a nightmare.Later we teach language and other skills like walking.It goes on as you know...Humanity as a whole is like a little kid as well.If we would know all the little, dirty secrets then we would riot and go mad.Things that are of no concern are nothing we need to worry about, so we don't get to know them either.Knowing how build the latest fighter jets is seen as a thing that would give a possible enemy an advantage.Makes a lot of sense to everyone as these things might have to protect us one day.The questions that remain are:If humainty is a child, then how old are we now or when do we graduate?If there is a collection of secret and old knowledge then who owns and controls it?What would it take to force the release of all the things people actually created for a better world and not to be locked away?As funny as it might sound but one answer to all these questions would be to do nice orund trip in your Repulsine.Fly over ever single country in this world.Let their guided missle and what not chase you and once enough show then how quickly you can make a 180° turn to get behind them.So called unimportant countries might ignore you and the people only enjoy a nice show.Those powerful enough will fear you and think it was "the other side" showing their superiority.Once done with your round they all will have to realise there is a new power that is at the helm now: Knowledge and understanding.No more secrets, a repulsine for everyone who wants the plans to build one.A new world would start.Ever thought about that when wondering why all these "Aliens" we see in their ships in our skies never land to say hello ? ;)Even if they would be Aliens and not just some human pilot in some experimental craft:Shouldn't this demonstration of absolute power and control without any violence tell us something?The Repulsine need to come back to life to end all this UFO nonsense and Alien theories out there.You hear the sounds, see the ligh show and impossible abilities.And suddenly most if not all UFO sightings would have a common factor again.Just because the Repulsine is claimed to be lost and that it never actually worked despite film evidence showing the opposite does not mean there is no one using the technology.A working Repulsine available to everyone would also kill the doubt on so many other old inventors and "fringe" scientists.Science and physics would need to be redifined as would be able to find a lot of missing links.I know there is not only a lot of people out there trying to get what they can about the Repulsine but also that there are others who try to prevent this.You have a really easy time getting permission examine some old and histrically important artefact from a museum than getting just a hands on approch for what remains of the Repulsine in various places.Not even decent 3D scans will be allowed.Anything like just getting a tiny pipe cam inside is rejected with the excuse it could cause damage.If the thing is a hoax and never worked then why would it be so important to never touch or move it? ;)I recently got word that two of the remaining Repulsine "artefacts" were examined by the same group of "scientists".This happened in the late 80's and said scientists were claimed to have had acces to a collection of spare parts for the original Repulsine that was lost after the war.A private collector was also mentioned who denied all access but what he had in a secure storage facility appearently disappeared shortly after his refusal.Putting all the dots and hints together it would mean that someone in the late 80's was able to get literally everything that is left of the project in his hands.Those who claimed to have seen these scientists working on the Repulsine leftovers claim they used top notch technology to do so, including 3D scanners - and those were basically imossible to get back then for any uni out there...The laptops used were said to use touchscreens and were connected to all sorts of equippment.And they did it in almost total silence, like a group who studied a performance many times and knew exactly what do when and where without the need of many words.Professional in examining something unknown all all possible levels.I was unable to get any information on these scientist or who they worked for.But if you are one of them and readin this then I would love to hear from you!

I bought an assortment of components: resistors, diodes, capacitors, all mixed together on about a meter of cut tape from a reel for an automatic PCB populating machine. The original reel was marked as surplus from DEC and looks to be about 20 years old. One of the components is this black cylinder, like a very fat resistor, about 5 mm long and 3mm diameter. No resistance or diode action. Brittle and crack off with a pliers like ferrite. They do not melt or burn with a candle flame. The wire lead goes straight through and out the other side. Can be picked up by a magnet, but are not themselves magnets. They have no markings of any kind, but have shiny flecks. Are they some kind of magnetic tape position marker to tell the insertion machine what component is next? Say like a binary code?

So it's been awhile! Between school, homework, work, and playing with gadgets and such, I haven't gotten the time to post or make an instructable for quite a long time. But now, I'm back with a question. I see lots of new users here, and to them I say welcome to the community! You are going to love it here, everyone is helpful, and you'll find answers to just about everything. I also see some members here that were around when I still used instructables. Remember me? How are things? :P Ok, so now for my question. A few weeks ago, after flushing the Toilet, a strange noise began behind our refrigerator. It was king of like a rattling, but not so much that as say, a prize wheel at a gameshow spinning and hitting something heavy. It's really quite odd. The refrigerator is a model with the built in water and ice dispenser. I googled it, and many seem to say it is something called "Pipe Rattling", but I don't think that is what it is, because it only started a couple of weeks ago and we have had this fridge for a year. I have drawn a diagram of the first floor of our house to help you get a better understanding of where the fridge is in comparison to the bathroom and the toilet. Like I said before, the noise only occurs after we flush the 1st floor toilet. Another odd thing about it is when the noise occurs. It can make this rattling as the toilet is flushing, directly after the toilet has flushed, and it has happened up to a minute after the toilet is finished flushing and refilling the bowl. The noise goes for about 5-8 seconds each time, and it only sounds once after each flush. We have not made any additions to the house before or since it started, have npt experienced any severe weather, and have not modified any plumbing in the house in quite a while, and never in that area of the house. In the incredibly bad sketch I made, you can see the bathroom, and the incredibly bad drawing of a toilet. The fridge is indented in the wall so there are cabinets surrounding it. Any thoughts on what this noise can be?

I purchased a couple of rose bushes from a mobile vendor and this small seedling was growing alongside one of the bushes. At first, I assumed it was a weed, but now I don't think so. The seed it sprouted from is fairly large. Can anyone tell me what the name of this plant/flower is? The leave are just a couple of inches long now, but I imagine they will increase in size as the plant matures. I'll let pictures can do the rest of the talking. ;-) btw... I am in zone 9.

I'm not sure what's going on, but... I submitted an Instructable on 30 June. It was subsequently featured in the technology section. A few hours ago, I noticed a new draft of that Instructable, all in Spanish. The Spanish version of the Instructable was just published a few minutes ago. I neither created the draft nor published the Spanish Instructable. Was the original Instructable translated by an administrator? Is this normal?

We've had quite a bit of rain over the Summer and this charming indigenous succulent is growing like crazy all over the Baja California Coast. It's hard to see from the photos, but the entire plant looks like it's covered with tiny water-blisters. It literally glistens! The flowers open in the sunlight and close at night. The size varies, but I've seen them grow as large as 8" tall and 2' across. It looks like it belongs to the Drosera (Sundew) family, but I've been unable to identify it. Any ideas?

There’s an elementary school on the next block about 100 feet away from our house. Everyday from monday until friday, the noise coming from this school wakes me up about 6.30 am. What puzzles me is how could the noise reach me when our house is inside our block and the school isn’t even facing our block! -also how the noise could be ignored by the school’s nearest neighbors when it’s so loud at 100 feet away. Another thing is the voices I hear are too big and loud for elementary age students but I don’t see any high-school aged teeners at the school. And the greatest mystery is that I only hear the noise inside my room -never outisde! I know there’s a scientific or audiological explanation for this but I also know that getting the answer would take a lot of time and I just don’t have that. Can anyone give me the explanation for this?

No camera editing of any sort (no contrast or anything: it's really that brilliant Big Bird yellow). Found it in the woods here in Northern Vermont. What is it? It looks so cool, doesn't it? Photos taken summer '08.

The attached photo was taken recently at an undisclosed location, somewhere in the Former United States (FUS). In it you can see a plastic sign-thingy on top of a moving car. My question is this: What mysterious forces keep the plastic sign-thingy from sliding off the car due to the effects of wind and inertial pseudoforces. What holds the sign to the top of the car? Is it powerful magnets? Double-sided sticky tape? Is it perhaps... love? Has anyone seen one of these artifacts up close, and/or knows for sure what the physical mechanism is?

So i opened this old Crown Japan stereo and found somethings i've seen before, but never had the initiative to ask their raison d'être (why are they there?). 1 - What is the blocky component with a colored screwdriver notch on them? 2 - Why do they always use this specifics pots for the tuners of radios? 3 - Why do they apply wax (often in generous amounts) over some components? (i know all 3 sound pretty noob, but i had to ask someone)

I can't seem to find a definite answer anywhere. I'm not sure where this fits in here, but I'm hoping someone might have something to pass along. Thanks so much! =^..^=

You're looking at a photo of what I came to call the 'mystery machine', as I've no idea what it's real purpose is exactly. I suspect it's an old, big multi- or voltmeter. As I say in the question, I'm looking to turn it into an sci-fi monitor/screen/prop that's 'alive' somehow; continually generating interesting content. What I'm thinking of is replacing the big, central meter with a monitor/screen of somesort. But, what kind? Ideally, this'll be easy to make, stand-alone and cheap.

What symptoms of the standard green rat poison will be present in cats? For mild symptoms. (does anyone have experiance with this?) I have found that vitamin K is almost an antidote, although not sure. The symptoms listed here are not present, or we cannot tell for sure. No litter in the box, no noticeable bleeding yet, he has been acting funny like that all day yesterday too. I suspect it may be a very mild poisoning, but do not know what symptoms may exist for such. Thank you.

I'm cleaning out my junk drawer. This whatever-it-is is going to the recycling center if I don't foresee having a use for it. It appears to be some kind spatula? It's made of #5 plastic and measures 11"x 1". What the heck IS it and what is it used for?

Scooby-Doo movies became famous for it, spy movies have been known to have them, Batman had one, and yet... I used to live in Kansas, before I moved to Arizona, and while I was there I visited a place called Science City. It is basically an indoor amusement park with funky gizmos like a hologram of a fist sized diamond behind a painting, and a rocking chair that doubles as a power generator. But the thing that interested me most was a wall that revolved at the center, becoming a door that would lead to another room. I asked some of the employees about it, but it must be a trade secret since they all said they couldn't, or wouldn't tell me. One of them even denied the existence of such a wall! Ever since then, I have seen various recreations like this in spy and mystery movies. I think that this would be the coolest thing ever. You see, when you turn the wall around, one side is a fake bookcase, the other is a blank wall. It turns 180 degrees, then you have to turn it the other way. I want one of those in a cabin that my family is building up in the mountains. Since it would have to be custom built, I would need a very good idea of where to start. Anything in the way of advice, answers, or even speculations anyone could give me would be absolutely great. Sincerely Yours, Zelback1
