Help to Dismantle a bench Vice

Hi I have a bench vice which I am trying to dismantle. I am having trouble getting it apart, when fully wound out it stops, I think because there is a pin visible from the back which turns with the thread. Would this prevent the thread coming right out? There is also a spring visible from the handle end, hopefully this information may help someone identify the type of vice I am dealing with. The problem with the vice is that it is very hard to turn the handle, I hope someone will know why it is stiff to turn and the possible cause and fix for the problem.Thanks, Peter

Trouble with cover images for Instructables

I have been recently seeing this problem. Whenever I click an image upside down on my phone and edit it to flip to normal, it gets corrected and comes in the correct orientation. After uploading the image on the editor, everything looks fine, even after saving the changes, but after refreshing the page after a while, the cover image again flips upside down. If anyone has solution, kindly look into this issue.

How to build a verneuil furnace for synthesizing corundum?

I've been researching the verneuil process for a good while now and I'm absolutely sure i could synthesize gemstones in my garage, the only problem is that I haven't the faintest idea how to build the device I need to do it. Aside form the few demonstration pictures I've found and a hand drawn sketch of the original furnace I can't seem to find any technical information on the design. Anyone have any ideas on how I could do this? http://en.wikipedia.org/wiki/Verneuil_process http://gemologyproject.com/wiki/images/thumb/e/ed/Verneuil.png/300px-Verneuil.png

Mini Bike Chain Adjustment Trouble? Answered

I recently bought a bunch of pocket bikes all in good shape but all had some sort of problem.  I took the best parts off of them and made one extremely nice bike.  The one problem I am having with it is that the chain likes to come off.  There is a bolt connected to the back axle that tights and loosens and slcks or tensions the chain.  How do I find the "butter zone" where it isn't too loose to come off, and it is too tight to come off?  The two sprockets are lined up really well, but they are a little off.  Would it be possible that that was the problem?  When I say a little I mean like so small its less then 2-3 mm from drive sprocket to driven sprocket.

Variable height desk: replace hand-crank with some kind of electrical motor

Hi, First time poster here, sorry if I'm misplacing this. I have near zero knowledge of engines, though I understand physics, at least from my civil engineering college years. I bought a variable height desk from IKEA (Skarsta model), which has a 12cm radius hand crank (see photos) that ends in a hexagon shape, h=6mm (so diameter around 6,93mm). This hand crank works fairly easily, needing little effort to crank the table up, with ~45kg of weight on it (it's supposed to go up to 50kg). So basically I was thinking if there was a easy, cheap and safe way of automating this with some sort of electric motor (I even looked up those Lego Technic motors!). Any suggestions? Thanks

Q: why can i switch the screen of a led tv on & off via its built-in usb jack?

Hi, had a broken usb-cable causing a short in a usb-a 2.0 jack of a tv-set. thereafter the screen went black (tho the rest kept working, thus: audio, remote,...).did open up the beast and, after having given it for a goner, started playing around a bit. bridged the (metal)-mounting-frame of the inside with the vcc+ pin of the usb, and, look-look, the screen came back on... turns out: each time i apply this pulse the screen turns off, and on a 2nd pluse it turns back on, a.s.f... sort of works like a switch (i always wanted, incidentally).... i am just a lucky stupid bastard - but can any pro here explain what the hell/heaven is going on here? thanks, pit

Sharpening a concave blades like Kukri or similar

Every now and then you have someone approaching with the odd job.This time it was in the form of an old Kukri / Gurkha knife.Wasn't expecting this when I was asked a few days ago if I could sharpen some old knife so it can be used for camping.The knife had a few marks from hitting hard stuff or maybe the occasional nail.But the worst was that for as long as guy had that knife it was only "sharpened" using a belt sander.You know, these tiny machines advertised to give your (kitchen-) knife the perfect edge.We could now argue about the pros and cons of having a knife edge that is literally rounded.But once it was done so many times that the edge really looks rounded it becomes obvious why this method only works for thinner blades.Adding to the problem was the fact that the belt used was just over 1.5cm wide.Appereantly so it is easier to do the concave part of the blade.Lets just say lengthwise it looked like someone created a wave pattern LOLThere was nothing "straight" on this nice blade anymore.Now, if you look up how to properly sharpen thise Kukri knifes then you can find all sorts of really useful tips.One I really likes was to use some eraser and toglue sandpaper on it.Small and flexible enough to cause minimal damages to the curve towards the handle.Another nice one is to use half round diamond file, preferable of a finer grit in the 600 region.Should work fine - if you plan to invest an awful lot of money on such a file.I however like things quite often done the old fashioned way.The oldest trick in the book....Whether you are using chisels and work on wood, just love to keep your knifes sharp or go on long camping or hiking trips - sharp knifes and tools just become your thing.The main thing everyone tells you is a super flat surface for whatever is supposed to sharpen your blade.For the normal stuff that is fine and good and you only need to flatten out your stones every now and then.But what about these odd jobs?Imagine you would need to sharpen a long paper cutting blade on some machine.Might be over a meter long and it has to stay with a perfectly straight edge.Back in the day this task was not done with some very expensive stone of large size....Instead sandpaper of various grit was used on a flat steel surface.I actually prefer a small pane of glass and tape my sandpaper on it.Hard to find anything finer than 1000 or 2000 grit but you might be surprised how well this stuff polishes onces clogged up a bit.Its all about the right level of wetness...Anyways, for our Kukri in question I decided it is time to do the same but in a way that does not harm the blade, constantly cut into the eraser and still is solid and "flat".If you still work with a sickle then you already know where I am going here ;)I used a small diameter spray can as my surface to hold the sandpaper.Of course a piece of PVC pipe, round wood or similar would warok the same way....Sticky tape does not work well with sandpaper unless you use double sided stuff.But it is enough to wrap one round on the top and one on the bottom of the sandpaper on the can to hold in place.So much for the basics....If you know how to sharpen a knife then you also know that there is a prefered way of doing it.Depending on the blade and stone in question you literally try to cut a thin slice out of the stone with every stroke.Either stright or with a cutting motion.This works fine with sandpaper on a flat surface, not so much however on a round surface.Try it and you see how you cut off the sand from the paper and constantly ruin your edge.The only way to do it is to move with the edge.You start from the heel and stroke to the tip.The can is used likea sharpening rod and shall always stay at a 90° to the curve of the blade.Takes a bit of practice to find the right grip to hold the blade while moving and twisting the can but well worth it.The rounded surface only allows for a very thin area of the sandpaper to work on the edge.I started with 120 grit!!!It left a trail of destruction on the edge, at least in the rounded up section....Once I only had a very thin bit left on the edge from the old sharpening I switched to 240 grit until a flat edge formed.As the Kukri was a disaster this process still tok over 4 hours to complete.That blade was properly hardened too...The start of the finnishing was done by jump right to 600 grit paper.The first can was just slightly smaller in diameter than the concave bend in the blade - perfect to smooth out those nasty bumps.But with a burr forming now on the edge and minor mishap with angle of the can towards the curve of the blade would mean cutting into the can while sharpening the concave bit.Meant I used my emergency insect repellant can as I did not like the idea of hoping my pepper shaker would start leaking while sharpening ;)If you blade is not too damaged you can of course start right away with a smaller diameter.The process is the same as before.Move along the blade and keep the can at the 90° angle towards the curve.Once you feel a burr forming on the side turn over until you have a bur on the previous side again.Repeat until all the marks from the coarser grit are gone and the edge has a uniform shine.Switch to a finer grit and go as high as you can here.I had to stop at 1000 grit as my supply of 2000 and 4000 grit is out.Hints and tricks along the way....It really helps to do this sandpaper sharpening under running water.The paper won't clog up, you won't risk a losse grain making really deep marks...But on a bad blade this can take several hours and would do it with a small aquarium pump or so and some gloves.A fine but stiff brush and soapy water however do wonders to clean up used sandpaper!I prefer to use these re-used pieces before switching to a finer grit.In most cases they are already finer than the next grit and create a nice polish that makes the visual confirmation of your right angle and angle of attack easy.A kukri is a working blade!It is mot meant to make fish filet or shave you legs.It is somewhere between axe, big bowie knife and hatchet.That mean if you would dare to give a 8° angle either side of the edge you would have a pretty damn wide edge...Stick to the original in width but keep it nice and flat.It is good compromise between cutting sharpness and durability when for example chopping wood for your camp fire.DO NOT USE A BELT SANDER!!I said it before but have to repeat it again as there is people using a big belt sander with enough free space to add a set of wheel that creat the curve I got from my spray can.The guys in India that make these knife do this blind folded....It takes years of practise to get the steady hand required not to cut through the belt.The beginners start in reverse, meaning the belt runs towards the edge.These guys only to the basic forming of the edge with really coarse grit.Basically to remove the marks from the forging.After that the pro takes over the blades and he has the belt running towards the edge!If you are silly enough to try it at home be prepared to have the belt flying in your face very violently!!The reverse sanding can't be used to finnish a blade as you never get a proper sharpness and flatness right on the edge.So just stick to manual and take an hour or so longer but then be able to enjoy a cold drink when done.You need surprisingly little sandpaper in terms of clogging up and getting useless until you get to the finer grits.If you use a wooden dowel or similar then make it a bit longer and add strips about 6cm wide of sandpaper.This way you have all the grits you need in one place and can take them with you to keep your blade sharp ;)If you glue it onto the stick it is also quite easy to give it quick brush clean when done.The really tricky part starts from about 800 grit onwards.Every mishap on the concave part can mean damage to your paper or to your edge.When using stone most beginner think that using a lot of pressure is a good way to remove the material quickly.In reality however it is just a sure way to wobble the blade over the stone, especially if the blade is not fully straight.Sandpaper can be more aggressive than your stones as in our case you only work with a little area and every time you turn the can only a little bit you have a fresh piece of paper working instead of a slurry building up.This mean you really do't need much pressure at all.It is the repetition, not the pressure that gives you the edge if you don't mind the pun here. ;)For a real working knife stopping at 1000 grit once you do single strokes either side of the blade is sufficient.The tiny burr left will disappear quickly during use and the Chakmak can be used for a quick refurbishing after every longer use.Should mean you only need to get the sandpaper out once you edge actually started to get blunt again.The final stroke....There are those people that don't have a kukri to go camping...Some people like to collect them.Restoring an old kukri can be done like with any other knife.That is until you want a razo sharp edge that is also highly polished.This is quite possible with the original edge width on the kukri.But of course you can only go so far with sandpaper....Modern technolgy provides us with the solution in several options.Firstly we have the ceramic sharpening rods.Unless you can do with kitchen variety thickness you need to pay a lot of money.A short 8cm diameter rod can set you back over 100 bucks with ease.Especially if you want something that provides a mirror like finnish.And alternative that is often available relatively cheap is a ruby rod.They can often be found with slight damages that make them useless for laser applications.Even burnt out rods are still fine as long as they are not cracked.It is quite hard (literally) to give them a satin finnish but I found that good quality sandpaper is sometimes capable of doing it.I like one side smooth and the other half of the rod with a satin finnish to prepare the edge.On the budget there is quality wet and dry sandpaper as commonly used in paintshops.If used dry the finer grits tend to clog up on such a wide edge.Once you have a piece of 1000 or finer grit that is fully clogged up you can use to give the edge a final polish.With this you won't even need a leather strop anymore but as said it takes a lot of practise so you won't cut the paper in the concave area.The steel rod....If you happen to have a hardened steel rod, like from a motion rail, small drive shaft or a big drill then give it a try.When using a drill:Of course use the end of the drill, not the working part ;)Also make sure it really is motth as any burr from the chuck or such will cause deep scratches on your blade.If it starts to feel sticky after a few good stroke you know the drill method is working.If it continues to feel very smooth and you don't see any polishing effect at all if tried on a small area only then you blade is of really good quality.But then again you would have confirmed that already by the ongoing swearing during the endless hours trying to remove some material from the edge...A word of advise for the first time user of a kukri:Although a good kukri is hard to damage without hitting a stone or metal, you can make blunt very quickly.It is top heavy blade and requires a steady hand when working on other things than meat.Chopping into some wood and letting the blade slip can deform your edge.A little mishap can be fixed with chakmak but not if hit hardwood badly a couple of times.And tempting as might be to use it as a small hatchet or axe to split your kindling:Never hold a piece of wood and then hack into it from the top with your kukri!Not only can you miss the wood and hit your hand, the wood can also split far easier or in unexpected directions!If the kurki is sharp you then have a good chance to loose a finger or two!

Decoding and understanding what your SDR scanner is receiving!?

For some reason, every time I upgrade my antenna I get more signals on my screen that I fail to decode or even understand.When I started this hobby it was mostly about voice transmissions and trying to get radio stations from overseas.Now I am starting to wonder what is behind these endless amounts of transmissions that my software fails to decode or recognise.Some things like TV, pure data or trunked system like the P25 are usually not a problem to identify.An awful lot though is not recognised at all.Also found quite a few signals that produce sound that just isn't right.No matter what type of audio is selected thest I describe these sounds is like weird space sounds with a lot of echo in them.Like a base tone that goes up and down in frequency and is overlapped by blips and beeps.I am not good at all with Linux.You could say Linux and I are like a cat and a dog locked in the same room ;)So I only used the common programs available for SDR decoding use that work with Windows.I guess my question would be:Is there a software out there that can identify the received signal automatically?You know, if doubt be routing the audio to it and getting something back like "Encrypted P25, LoRa data, DVB-T,....".And for whatever is not recognised directly at least something to help identifying the signal.A lot can be done by just researching the frequency allocations.At least down here they are quite strict and that means if you find some info that a certain frequency is reserved for data transmission on short range you can tick them off.The ideal thing of course would be something that works automatically as a complete packet.But I guess that will be a few more years till we get that pleasure :(

How to boost voltage of signal generator frequency? Answered

Okay, here's the question/challenge... I'm using an AD9850 signal generator IC to create various frequencies which works great. Input voltage is 5-volts. However the output is only around .5-volts. What I need is to be able to boost that to (ideally) around 45-volts without affecting the frequency created. The ultimate amperage I am working with is only 20-600 microamps so the boost shouldn't be a problem (I think). I've independently used voltage boosters but wonder if those affect the frequency. Then from there I want to make the current biphasic (reversing polarity every 3-5 seconds) so I'm assuming a relay somewhere at this end. What say the resident experts here?

Important Changes to Contests - May 1st

Hello everyone! As most of you have probably noticed, we haven’t changed much with our contests over the last several years. But this year we’re changing that, thanks to all of you and your important feedback! In 2018, we are going to be trying new things when it comes to contests. We believe these changes will lead to a larger variety of winners and even more incredible instructables!With that said, we’d like to announce two major contest updates starting on May 1st. #1 - Every instructable can only be entered into ONE single contest.At first, this may seem like bad news, but we promise it’s actually good: the new rule will allow more authors to win prizes! We’re reducing the number of prizes ONE instructable can win, but this will allow for more winners overall. While we’re sure some of you will be disappointed, this is a great way to level the playing field and simplify the process for both authors and judges. The old contest system allowed an author to enter three contests with one instructable, which greatly increased the number of entries per contest. Along with increasing the number of entries per contest, the old system tended to pit new authors against much more experienced authors who understand that they can up their chances of becoming a finalist by working multiple contest themes into an instructable. We hope this new contest rule will encourage our authors to commit fully and enthusiastically to one contest theme and create more focused projects, instead of stressing about making something to qualify for three separate contests!.#2 - We are creating more Prize Packs.Currently, if you win a contest at any prize level you will get an Instructables prize pack, some stickers, and whatever other random swag we have lying about in our prize room. As it turns out, this has created a situation in which our best authors end up filling their homes with piles of instructables T-shirts. We recognize that winning T-shirts over and over again is boring.To make Prize Packs Great Again over the next few months, we are going to roll out new Prize Packs on a permanent and limited edition basis. When you win a contest, you will be able to select the standard T-shirt prize pack, but you will also have new choices coming soon.Make sure to keep an eye out soon for new Instructables swag we know you’ll love!

Is a CRT electron gun any use?

Is it worth it to take the electron gun out of a CRT when salvaging parts? I've seen people remove the electron gun when they take apart the CRT but I don't know what they'd use it for. What can you do with a CRT electron gun? What chemicals does the gun contain? (I know the screen has toxic phosphor and stuff but I'm talking about the gun itself). Also, is it safe to vent a CRT tube? I have found that you should vent the CRT tube before working on it, by smashing the end from a distance, so that it won't implode if you happen to break it when working on it. But is it safe to puncture open the tube? There are toxic phosphors inside and I worry that venting it could cause toxic chemicals to go airborne.

Does the strength of the electromagnetic field of a coil depends upon the thickness of the wire? Answered

Whenever I have problems with the magnetic field strength of an electromagnet people tell to use a finer wire, I have some, its thickness is not more then the thickness of a hair, but whenever I use it, I have difficulty in connecting it with the battery because it's so thin it easily breaks off, and when I turn on the switch, it burns up instantly, maybe I am not using enough length of it. So does the field strength really increase with the decrease in thickness of the same length of the wire and same diameter of the coil, if it does than why?

Hello, everyone. I need a little help! I'm not very skilled in circuits, but I have already did something similar with a different device (following some tutorials from instructables); this time the same approach seems not working.I have a sensor which triggers a timer relay; when the relay is triggered on i would like to switch on my fog machine (which is already turned on and heated) and spread the fog until relay reset.From the relay I have a COM and the NO(/NC) output.I need to connect those outputs to my fog machine cable controller (which i cannot unmount completely). I attach here some photos of my circuit.The first image shows a red area (short circuit!), and two green areas (fires fog): if i connect the relay output there (COM or NO or NC) circuits reacts even if the relay is off.I have tried connecting the relay out to blue/white wires but nothing happens.What can i do? I'm starting to think to connect only NO (or NC) to both blue and white wires. Any help is appreciated.Thank you so much.- - - - - EDIT - - - - -Thanks for the first 2 replies: connecting COM and NO to blue and white cable was the first thing i did, but with no success. I tried again (maybe i was doing wrong), but again no success. I add 4 new pics of the circuit from above (i have dismounted it). Hope it is much clearer now.Thanks again for your support.

3D Viewer

Instructables Team - I don't know when it was changed but the "View in 3D" upgrade works very well. I especially like the section analysis and exploded views.Makers - if you are like me and enjoy showing your work in CAD, please consider dropping STP/STEP files into your instructable.

Some of the current Ebay and Paypal scams to be aware of

Recently the spam activities increased for my inbox and with that the amount of phishing Emails and direct scams.Today I will only focus on the big two: Paypal and Ebay.1. General Paypal scams and phishing mails....Most of these are really easy to spot.Genuine Emails coming from Paypal always address you with your full name!Scam or other bad Paypal Emails will use your Email address or just your first name.There is a problem with some users here, but I will go into these details a bit further down.In most cases the scammer will spoof areal looking Paypal Email or server address.This means in your Email client the sender appears as "Paypal" and not some cryptic server address you can find in the source code of the offending mail.The simple scams use links to malware or phishing sites - often trying to look like the original so be aware of this.2. The latest and for some hard to spot Paypal scam.You are more likely to become a target if the Email looks genuine enough to fool you to click on some link in it.A lot of users do a quick check with the mouse on some links offered and check in the bottom left corner for the link that appears.Sadly in the latest scam mails the scammer uses genuine graphics and links.In some case directly from the Paypal servers, like logos and backgrounds.Only one link is in there that will fool you.If the scam informs you about a payment you supposedly made than it will be the link directing you to your account to cancel the payment for a refund.If the scam mail is about a refund you got then it is the same link - the one making it easy for you to get to your account settings.In one scam mail I landed on a really good looking copy of Paypal's login portal.The address bar however did not contain the usual secure HTTPS and neither a genuine address going to paypal.Problems with these new scam mails happen if you follow the suggestions or free will for naming your Email account.If your Email is for example tommy19726@mymail.com then you will spot this quite easy in the scam mail when you are addressed as tommy19726 instead of Tommy Hilfinger.It seems to be a favour now to have a real looking Email, so Tommy might have used Tommy.Hilfinger@mymail.com.And then in the scam mail he would be addressed as "Tommy.Hilfinger" - only the DOT is then different to a real Paypal mail!!!If you have one of these Email addresses with no numbers and just your first and last name then pay specail attention when checking Paypal mails!!!3. The latest Ebay scam from China :(Lately I had to order quite a few things that I could only get through Ebay for a reasanable price.Shipping costs were the major problem with other sources as I don't see the point in paying much more for postage than for what I bought.Anyways, the scam goes like this:You order something with a value above about $50.You get the usual payment confirmation and a few days later a tracking number.Problem is that this tracking number won't get any updates at all.It usually only states "Shipping information received".This means someone in China requested a shippment but never actually lodge an item or had one picked up.You can't do anything through Ebay until the max delivery time is over.Trying to get a working tracking number from those seller only gives you excuses but nothing of use.In many cases the answer you get has no relation to your request!Once the last date to get the shippment is over the seller keeps stalling and asks you to wait a few days more.No attempt to explain that the tracking shows that nothing at all was sent on the way gets any useful answer.It is like talking to your digital assistent set to a language you don't speak.Once you start a claim through Ebay the case and refund is handled quite quickly.Does not mean you are left alone by the seller, especially if you did the right thing and left negative feedback.And no surprise, suddenly the seller is then even able to uderstand your language LOLBiggest thing is that these dodgy seller are adjusting quickly.Once you state in your responses that you will open a calim they usually "offer" a refund.Even if you clearly state you want the item and not the refund you will get a nice thank note back and then a refund that makes a claim impossible.You are left with no item and can wait another 3 or 4 weeks if you find trustworthy seller that is.Only chance is to open a "Item not received" claim right after the last due date.But even if Ebay agrees and provides you with a refund, as they have no interest to do more, you need be quick!The item in question will end in the hidden section of your purchase history.Only if enable to show your hidden items you can then select it to rate at least the transaction for a negative feedback.If you act quick enough you can even leave negative feedback in the usual way, but only through activating your hidden items.What can you do to stay secure?The easiest way for Paypal is to simply ignore all content in any Email you get that seems to be from Paypal!Whatever you do or feel you need to check: Go directly into your Paypal account through the app or with your browser but DO NOT use any links provided in any Email.If you think an Email is suspicious then just forward the Email to "spoof@paypal.com" - or .com.au for Australia, .de for Germany and so on.In case the Email is genuine you will get a corresponding response.If the Email is indeed fishy then Paypal will notify you to delete the Email in question.For Ebay the problem is not s easy - at least if you don't buy locally.From my end I can only state it is the Chinese sellers, Hong Kong and mainland.And a few years back the recommendation was not to buy from a seller with less than 95% of positive feedback.You can try it yourself and mess up one sale if you are private and see how badly your feedback goes down - just kidding, please don't try!!!With the introduction of "power Sellers" and Ebay stores however this guide was rendered totally useless.A power seller with 99.7% positive feedback can still literally have hundrets of negative feedback comments for the past few months.Quite often you see it spiked a month or 6 ago - a clear indicator the seller is going to new account and tries to make as much quick money as possible before Ebay closes him down for good.If in doubt you really need to check the negative feedback in detail before buying.Some really dodgy sellers make all sales "private".This not only removes the item from the feedback but also the sale price.Intended only for special uses, Ebay sees no need to stop this misuse.If you can't see detailed feedback for a seller then just don't trust the seller!If you see way too many negative feedback comments during the past 6 months then stay away!Click on other listing showing identical listing images and you can be almost certain that even if the seller name is different it will be the same scammer.You can usually confirm this by seeing a similar pile up of negative feedback with that seller.Why do I stress so much about Ebay scammers if you get a refund anyways?Interest...No really, I mean interest in getting it for the money in your account.Firstly, if you wasted about 100 bucks and waited a few weeks for finally getting a refund, then you were out of pocket twice.Once by paying for something you never got and then again for the money you lost in interest.Sure on your end only a few cents worth...But see it from the other side:Have just hundred transactions of $50 going into your Paypal account where you never actually bother to send anything.Add a longer than usual shipping time and make it free.Means you have $5000 in your account collecting interest rates for 4 to 6 weeks.Do it on an even bigger scale and you can invest 10.000 or more on a regular base.With up to 10% of interest on foreign currency Chinese banks are only too happy to take it.Or did you never wonder why an item sold in Greece needs to be paid for in US Dollar, UK Pound or Canadian Dollar? ;)A good Ebay scammer can make over $25.000US in interest rate payouts this way before Ebay even decides to limit or monitor his sales.And once Ebay or the feedback rating goes to negative on him it continues on another account with the same items and availbilities.Quite often you can find a seller has let's say 5 items sold and 12 still available.Isn't it then funny and of course pure coincidence that another seller has the same, hard to find item, with the exact same 5 items sold and 12 available?Ebay has no interest to actually stopping this in any way, Paypal also prefers to look away if the same account is used for multiple Ebay accounts.Not even the need to provide the Paypal details of the seller in plain english is a requirement anymore.You need to use a translator to figure out what "company" is behind the Paypal account and it never matches the Ebay account in any way....I did some checks on the few suspicious sellers that still had at least item prices listed with their negative feedback.There are some out there having a vlue of well over $12.000US in "not received" claims over the last 12 months.About a year ago I tried to start a little (ad sponsored) reporting service online.Scammed Ebay users were asked to provide the details about the item, Paypal address of the seller and the amount/time until refunded.Within 3 days of going online and with only having two users that reported a scammer my provider gave me a shut down notice - effective immediately.A few days later I got an Email stating my website was shut after both Ebay and Paypal stated I would violate their privacy terms and break US law.Needless to say this notice also included a note informing me that if I attempt to conitnue to provide such service I will be taken to court for legal action.So what was the fuzz all about you might wonder?It was planned that users can provide the required data, without this data actually showing up anywhere.Once the databse was full enough a user could enter a seller or shop name or even a Paypal account to have it checked for negative things.You either get "unknown" or a list that states when and how many users reported this seller.With no deatils about any transactions, item numbers or user names linked.Did I mention how supportive Ebay and Paypal were when I contacted them about the take down notice? ROFLRules and regulations...I pointed these flaws out to Ebay and Paypal more times than I can count over the past 3 or four years.But as always, money is all that matters and those scammers won't be stopped.If you get a refund then the seller will be punished by more than your feedback, only if the Paypal account he used was unable to provide the required funds.In the rare case the Paypal account disappears with the seller you will notice the refund comes from Ebay or Paypal but not from the seller's account.This is the only real buyer protection Ebay has on offer.The rest is just following the pressure of local laws, especially in terms of refund and warranties.Does not mean though a warranty for an Ebay item will be honored by a company....If you start selling on Ebay then one big requirement is to have a validated Paypal account.Also a real physical address - although this is only too often just taken as granted once you had a delivery to your nominated address.Either way you Paypal account's address and name must match what you used for Ebay.Means if things go really south both Ebay and Payl will have enough details to surrender you to the local law.In China however things are different, starting with space.An export business is highly subsidised as it brings in foreign currency.So you can just hire a dummy letter box in some office building for company purposes.All mail however will be directed to whatever real address you specified for your "company".Same for actual company grounds.A n awful lot of producing factories/companies over there get additional support by the government for supporting small export businesses.That means you, as a little Chinese Ebay power seller forward your orders to whatever factory produces or stores these thing in huge amounts.This company then does all the shipping for you.Becomes really clear once you try to figure out from where you Ebay shippment really came.There won't be any Ebay seller name on the address, same for whatever you found in the Paypal invoice.The guy can just sit in his lounge room and never actually touches any shippment at all.In mayn cases those sellers have good discounts and since small items ship for free out of China, no one complains about the extra work.Both Ebay and Paypal are well aware of those loop holes in China!But as with multiple accounts they look away and prefer not to act as long as the money keeps flowing.

Can you cheat on contests?

So I was browsing the contests and found an instructable that seemed kinda suspicious. The instructable itself was fine, but in the comments section I found about 8 users, all praising this "amazing", "genius" instructable, and when I checked the accounts, they were all made and favorited and commented on the post on the same day, and that was all of their activity. Oh yeah, the author also commented. I'm also guessing that they all voted as well. My question is, will this be overlooked, or will this author win possibly runner-up with their instructable for cheating? I hope that this will be noticed and will be thoroughly checked. Thanks,Zakbobdop

Smoke

Hello, I have an e-cigarette pushed into the cushion of a Whoopee cushion, and taped to tubing that runs under a black matt. A whole in the matt allows smoke to rise from the matt when I step on Whoopee Cushion. Problem Whoopee Cushion pops and doesn't give enough smoke to be impressive. Would you know of a solution like some kind of mini smoke machine that will give the smoke we need? Below attached is photo of Whoopee Cushion, e-cigarette, and tubing running under matt. Thank you, Alexander

Powering a Salvaged Window Motor with 20v Battery (HELP!!!)

So earlier this month, I replaced the window regulator in my Honda Accord so I can sell it later on. After looking at the old regulator to see what was broken, I saw the motor component was perfectly fine, so I salvaged it for a future project! I do have a few ideas for what to do with this, but my main conundrum is how to power it when I have no 12V batteries lying around.I do have a Black & Decker Cordless Drill that uses 20v Li-Ion rechargeable batteries, and the shape of the battery is pretty compact. Its got 2 POS and NEG leads which you slide the contacts inbetween, and I can 3D print something to hold the battery in place for the project I intend to make with it. However, 20V is clearly overkill for this motor and that means I need to convert 20V to 12V. Does anyone have any ideas how to achieve this?

Still don't understand why.....

I still don't understand why it takes me 6 clicks to get to the "recent" page. If I'm logged in and click on the "feed" button, it usually takes me to an error page (but once in a while it actually works). I have to log out, then log in again before attempting to access my feed. I've tried clearing the cache, cookies, and history first, but no luck. I use the latest version of the chrome browser. I haven't tried this with any other browser. I'm not interested in switching to another browser just to access one website. I've experienced this on both windows 7 and the chrome o/s. Simply clicking on the feed button seems like it should be just a simple thing.Once again I've placed this comment in the "workshop" category and "woodworking" channel, since there is no category or channel for feedback on website issues.
