How can I make a grain moisture content sensor that can withstand high temperature?

We are working on a multi-grain dryer (controlled by Arduino Mega) that dries a corn to its required moisture content (mc). If the mc is near the required (ex. 12-14%), the dryer will stop automatically. We need to make a sensor that can withstand up to 140F while the drying is ongoing. Meaning, the sensor is inside the dryer reading mc every couple of hours. If there is any device, will the reading be affected by the heat? we are pretty low on budget now so we couldn't afford to buy any pricey device and I think its hard to ship to our country in terms of period since we are pretty much running out of time for our evaluation.

Can I use CAT5 for running a 12V DC (Power over Ethernet) to connect to a surveillance camera 12V DC, 500mA? Answered

Hello, I want to set up surveillance camera system in my house.  The house is already prewired with 2 cables (1 CAT5 & 1 Coax RG6) at each end (1 end at camera place and the other end at main box).   I also have a Power Suply box with out put of 12.3V DC and 5Amps.  I want to use Coax RG6 for Video transmission and CAT5 for Power transmission.  The distance to run cable from a surveillance camera to a main box is about 40feet - 50feet long.  I'm trying to use a CAT5 cable for 12V DC to run for my surveillance camera (12V DC 500mA), I use 2 pairs for positive (4 wires) & other 2 pairs (4 wires) for negative.  I wonder if I do this way, will it have any hazard at all?  Please advise! Any advice/help is appreciate! Best regards, DP

Battery powering a Mini ITX Gaming Desktop? Answered

Hi all, Firstly two things; 1) I just wanted to say thank you so much to all of the guys on this answers section, for giving a lot of their time whilst being incredibly helpful, patient and overall just awesome! Just to name a few of the most consistently helpful; steveastrouk, Kiteman, iceng and Downunder35m.  2) I know this question has been asked before and asking it again has been my last resort after trawling the web as I know reviving old topics can irritate the OP etc.. But anyway: I am building another PC, with the challenge of it being a portable 'console killer'. The idea is to make a Mini ITX gaming PC as small as possible (a challenge in itself) which can run for an hour or two on battery and then needing to be plugged in and recharged whilst still being usable. The current specs;  Asus H81I-PLUS Intel H81 DDR3 Mini ITX Motherboard (1150 Socket) Intel i5 3.2Ghz Processor Zotac Nvidia GeForce GTX 750 Ti 2GB GPU CPU Liquid Cooler Corsair Hydro H55 120mm Fan So I need all of this...   ...battery powered... So I was thinking; all a PSU is is an AC adapter and step down transformer. So all I would need is several laptop batteries (and a way of charging them seperately) , a way of mounting them, a voltage regulator and wiring to power the computer and bypass the battery AND charge it when I am using a laptop external PSU. Right? But then, is the high current from a wall socket necessary to a PC's function? Thanks!

Free Energy - Am I insane or is it time to wake up?

Some might have noticed that I started a few, lets say, unconventional topics here.I added one just as a response to some very nasty feedback I got in other places.If you wonder what I am talking about check my topics about all things related to magnetism, "free energy" and such nonsense.The feedback I got was directed personal enough and verbal enough that I decided to increase my speed of seeding bread crumbs that might allow other people to "see" things slightly differently.Being called insane and mental case is the only things I use here as most of the rest would qualify as insults of the worst kind.The goal that was claimed I totally missed is to make people open up.Science or knowledge is as fluent as life itself.It eveloves with us, around us and through us.But we learned to use technology mostly to replace humans and to make our life easier.With that laziness also a reduced "desire" for knowledge and understand evolved.It is now far easier to "Google it" and forget it right after than to acutally learn and really understand something.A prime example is the disappearing artform of creating Japanese swords.No industrial process can produce a steel as pure and with such properties as used to be "offered" to the master swordsmith.Both are highly specialsed and rely on each other to create the perfect sword that outlasts generations.Once tradition gives way to modern life even this art will become a lost artform.We lost so much already, be it species, health, enviroment or just a "clean planet".Instead of accepting nature back into our scientific thinking and understanding we will continue to fail and get even more reluctant to learn new things.The blockbusters of science are no longer finding new laws of phsics or trying to understand things.We try to go further and further and use more and more dangerous ways to "create" the energy we continue to use more and more with no regrets.Well, other than complaining about the bills for it, which we wouldn't have otherwise...Why do we need more forms of colliding atoms to create energy?No because we need so much, only because we want more and more and at "centralised" locations.Distribution, control, money...Allowing us to use solar panels to reduce our electricity bill is nice, but try to overdo it and make good money by creating you own solar panel park and you get into trouble already.You can't see it anywhere other then back to your provider.And you only get whatever he thinks is a fair price for it, usually far less than what you pay to get it.Once you reach zero some even won't pay you money at all.And since there is always winter and night times it is only good that there will be always a need for electricity from the grid.Just try to get rid of your elecricity, water and gas connection in a township or city in case you found other sources you get for free.....Even if you build new most won't even allow you to without these "required" connections.If you need waste waster you also need tap water you pay for.And since a waste water treatment is no longer hyginic enough (despite proving the opposite) you can't get out.Gas you might be able to avoid but if there is electricity in the stree than it is already a building requirement to provie to the builder...What if all this nonsense and fakery actually has a true background somewhere?Humans are not meant to fly but we developed planes anyways.What once was a dream for a select few is now the prefered travel mode ofr most going on a far away holiday.But it is only so popular because there is a big demand.And where is demand profit can be made.Like a farmer:If you have ton of corn like twenty farmers around you then your local price will be low.Sell them a bit further away and you might get a lot more.In return our demand is closly related to the demands of those that provide the source of your demands.We all need energy and we evolve into a society that will need more of with every new generation.I try to give you hint in the form of a comparison:If you have a nice man cave and love to tinker than you might have a framed hand drill on the wall to remind you of how it all started for your grandfather.Or in most case you just liked it and got it for 2 bucks from a garage sale LOLEither, imagine all electricity would be gone and lost forever.Suddenly this crappy drill becomes a status symbol because only you can do things other people really struggle with - you drill holes with ease...Imagine the rpice you could ask to sell it..."Free energy" is the same but sadly in reverse.If a company sees a profit than it will be utilised some way.And if it happens that energy is your main income and keeps you rich and in control than you don't mind paying two or three fortunes to someone so he can forget and is happy give you his machine.Or would you really say no to life of no limits and with nothing to worry for your future generations of kids and grandkids?A few tried anyway to make a furtune themself by keeping a circle of trusted persons and finding enough willing investors to get their project going.Even if you can find some flaws there are still doubts about what someone would go through the lenght of providing online updates, sales numbers, testimonials and so on for years.Funny enough actually finding someone who is sceptic and make him check and report about it does not work either.No big university orders one or asks to really check it and provide a real world testimonial.No government or legal agency steps in to stop the "fraud" either.What is real, what is fake, what is disguise - you can figure it out if you want to.Ok, I could, but why bother if litereally everyone one already did and showed nothing works when it comes to the great unknown?Exactly for that reason alone it is worth it!People might make money now from ads or through clickbait but the topic is older than the internet already.And the proof even older than electricity...So many people would not try unless someone convinced them to try it ;)Might be just a bad joke but gets the point:If you ask 20 people if you can swim through the river to get to the other side then you might get confusing answers.1. No problem it is safe.Fully true but the guy might be from far up the river where it has no crocodiles in it...2. You could try it but a boat is safer as there might be corcodiles here.Still leaves you the option to swim as you can't be sure about the reptiles...You could go on and create a near endless list with bridges up ahead and so on.What it comes to is that depending on HOW you ask and WHO you ask the answers can be as different as day and night.In terms of science and making someone understand it take the most basic approach possible.Remember that time in school when your math teacher confronted you the existence of negative numbers?The confusion with the zero and how to add, subtract or multiply...Your teacher might have been great or you a quick learner but imagine the worst possible way to teach you an understanding of negative numbers!You know that 5 - 8 equals -3.You learned that this is true and why it is so.Imagine your teacher would have explained this extra simple like back with the apples when learning to add numbers."If there are 5 people in a room and 8 people leave the room, then 3 people must go back in so that room is empty!"Makes total sense if you expand the number game from above to 5 - 8 + 3 = 0 !!No sense at all however if you do it with people ;)People are not numbers, pressures or volumes, they are "real" to us.We associate certain things automatically, other we learn to associate and interpret through learning.Learning however is no longer actually doing all that would be involved in less technological world.We like magic tricks because we fail to understand how it is done or sometimes even how it is possible.Today it is for entertainment only.A true magician would never use his skills to scam people.But spend enough and research and you can do the same trick you saw on stage.Some not as good or not all though - thats life...Ask a good magician how how long it took him to get his new trick ready for the stage and quite often you get to hear it was years in the making.Think about that fact when you judge what is possible by dedication ;)

Phenolic discs for whimshurts? Answered

So recently I found a webpage about someone using Phenol for a rotary spark gap for a Tesla, I had never heard of this material and don't know too much about it. For a while now I have wanted to make a whimshurst that is larger than the one I currently have (bought online, a gift from my family) but with my current one i have an issue with the acrylic discs not only not being balanced but also warped causing them to start vibrating on their shaft making it harder to turn the handle. I figure that because every piece of acrylic i have ever worked with has been warped that is would be best to find an alternative. My question is, would it be easier to keep phenol flat and balance or would it be best to stick with acrylic? another thing im curious about is this a material that would even work for this application? Lastly i would like to say that i did try doing a little research on this and didnt come up with anyone trying it for this purpose, i know that in some cases static can act a little differently than normal high voltage arcs (say, from a microwave oven transformer) which brings me to this question. P.S. im not sure what category this should go in, if anyone thinks there is a better one let me know and i will change it.

Mono pole / single pole magnets!?

I made a quite intersting discovery today.The use of mixed orientations for a stronger or more directed field on one side and a much weaker on the other side of a magnet is nothing new. But if you check modern wind turbines or even just any old hard drive you find "chokes". I talked about shielding before but combining shielding a choking provides again another level of manipulation.If you ask anyone who claims to know magentic field or sience in general then you right away hear: There is no such thing as magnet with just a single pole!Like a battery one pole can't exist without the other!Keep going and your conversation parten either get angry or declares you a nut case.Also said before: The laws of nature and physics are not set in stone or complete for that matter!We only use what we know, or to be precise what we told to take as facts.A magnet with just one pole is impossible to manufacture, if you only think like making the magnet like any other magnet.Even cutting it in half will only give you two normal magnets again.Why is that so?How are magnets made is what you need to know.No matter the material they start as a blank and during the final processing an intense electromagnetic field is used to "prime" them.Like you would do on a screwdriver the material then keeps the "charge" and becomes magnetic.And this process requires a certain orientation.Imagine a big hydraulic press to make the magnet with some super strong electromagnets right beside the forms.Explains why you won't find a block magnet with the poles on opposing corners - the form is not designed to be rotated ;)Ferrite magnets can often be machined.If you mark the field direction of a block then you could just cut it into the shape you need.Like a half moon, triangle, pyramid...The orientation does not change, so you need to create the cuts so your required orientation matches the orignal block.Creates a lot of waste, is messy and often the magnets shatter.Still not possible to create a mono pole ;)But it allows for a great deal of field manipulations.For example a thick north and a thin south pole would show very different field strengths at the poles.How to create a mono or single pole magnet then??If you think outside modern science restraints it is suprisingly easy!You see, unlike a battery the magnet does not care if the "current" flows back to its own pole or a pole from a different magnet.In a hard drive the choked magnets have a field strength between them that is not just twice as much as th one from a single magnet.The field between the magnets is very stable too!No matter where you measure it is the same.Place two magnets in the same configuration with the choke and all you get between them is a mess.To understand the reality with magnets I need to explain a bit more though:If it does not matter from where to where the field lines go the it becomes obvious that you can guide them.Horse shoe magnets of the old kind where just two steel bars with a block magnet between them!Take a compass and check from what distance your magnet will start to affect the orientation.Now take two iron bars, rods, block or similar of about twice that length.Place the compass between one end and the magnet between the other end.Even with a little gap your compass will still move!You just extended the length of the field lines and directed them somewhere else as it also works with odd shapes.We know know and confirmed how choking works and as shielding is basically the same thing but for a different purpose you might get an idea where I am heading already.A "potted" magnet, like what you find in a speaker or as a hook magnet utilises two destinct features.a) A ring magnet is used.b) The field lines are directed to a specific area.One has them directed into a gap for a coil like in a wind turbine, the other to the surface to massively increase the field strenght in that area.If you take either apart you will notice the magnet just by itself is considerably weaker.Removing a pole from a magnet...If you paid attention so far and have a few magnets around then you already developed a feeling for the difference.Lets crank it up a notch, shall we?Make this experiment:Take two identical magnets and a soft steel bar or similar of lesser thickness than the magnets.Usually around 2-3mm for smaller N52 Neodymiums will do.If you dare make the steel the same size as the magnets.Now place one magnet on the steel and use the other to observe the difference in feel.There won't be much and both poles should still fell like before only that the field is now slightly longer.Trying to get two magnets to touch at the same pole is really hard, but see what happens if you add the other magnet on the other side of the steel...Despite having the same pole on the steel they won't repel and stick to the steel.Checking the field now with a magnet provides a very different feel!It is like having a magnet with a split pole where the opposing pole now is in the center.Impossible I know but you have it in your hand, so deal with the explanation yourself ;)And if that is so damn easy then how hard can it be to actually remove one pole fully?Design of the impossible magnet...If you want the south pole only then it would be the entire surface of your impossible magnet.That means you either need to make sacrifices or get creative for the next steps.Easiest from my experiments is to sacrifice like all scientists do and allow for some minor gaps.I won't give any dimension or step by step instructions.Think 3D and use your imagination.Our impossible magnet starts from the center.All magnets used should provide the same field strenght!To be precise it means no matter their grade, the the "force" of the magnets should be as close to identical as possible even if the size is different.You can use stacks or different types/grades...The center is a square block of soft steel, or iron as pure as possible - it needs to have a low "resistance" if you compare them to batteries and to avoid confusing terms.On this "dice" you place one magnet on each face, preferably of identical size to the block.So, for a 10x10mm block you use 10x10mm magnets -simple isn't it.All magnets are place with the same pole onto the block!In out example to get the south pole outside you would use the north pole.Now use six bigger magnet blocks for another layer.This time they are placed in attraction mode, meaning you let them stick together naturally.The resulting magnet will be far from perfect but you will have a hard time finding a strong attraction to the soth pole of a magnet if you move it around your cube.If you check the geometry you will now see how 45° degree angles and matching sizes for the blocks would be beneficial.Using ferrite magnets you can machine them to the desired size and use a thin aluminium or breass frame to hold the outside properly together, like edging on a fancy tranport box or chest.Check the magnet now and try to find anything else but a destict south pole on all faces and corners.No more nother pole....Does that mean it really is a mono or single pole magnet?Since modern science does not even consider a construction like this to be worth testing you already know the anser.For those working on a different level with magnets it will be a true single pole magnet.For the rest it will just be another fake.As by science a permanent magnet is defined to have two poles and to have field lines going from one pole to the other.All modern machines using them operate on this principle and "fact".But if I would give you a block of steel that has a core of lets say brass and a suffien wall thickness...Then this block would appear to be a steel block and nothing else.Modern science fails to see a magnet any other than a battery!If the "current" does not need to go back to same pole and there is no need for the field lines to go back to the outside pole then it is a single ple magnet like the faked box is a steel box.The physical outcome or in our case magnetic field is what defines it!The contra...All good has some bad, magnets are no different.Purely scientific viewed it would be impossible to create a gap free magnet like I described.And because never all field lines will take the shortcut there will still be a small amount of "north pole" to be found on the outside.But if that is in the range of about 1% of the field strength of the magnet then I say it can be neglected for almost all real life uses of such a magnet.Like the Halbach Array it is just a neat way of manipulating and if you like bending the known interpretation of our scientific understanding.Possible uses for these magnets exclude convention designs and for this reason alone anything you create with them will be the target of scepticism to say it nice.Ok then, what real life uses could there be for something we never needed?The question is the answer, as the impossible magnet is the solution.Ever watched these shopping shows in the night program?"It solves problems you didn't even know you might get..."Means that if you ever get the ide that your project requires a single pole magnet then you know how to make one ;)All I can up with would go against common scientific understanding and teachings, so I will spare you with my use cases ;)And what is missing here to actually make it work?Quite a lot as you might have noticed in your experiments if you use really good test equippment.Not so much however if you consider what I said about shielding and choking ;)Provide a path of far less resistance and shield the rest that still bothers you.I am not providing a ready to go model here that you can buy, someone else will do that if they see a financial gain it.My gain is provide a new understanding of things we forgot by giving your brain things to work with and develop.You might still say in the end that my way (or your results) are not good enough in some way.But then please also consider how many other people or documents you might be able to find that would have provided you with this information.Free energy is only a myth for as along as we allow ourselfs to only trust what modern science allows us to have.Allow the old knowledge in and every now and then simple ignore what you know and things become possible sooner than you might think.Wind and water were used as a source of free energy since the dawn of mankind.Our first motorised boats used the same "wheels" we already trusted to be driven by water to power a mill, saw or similar.And after we learned about motors we also found a way to make wind - by reversing our trusted wind mills into a fan.Instead of using the free energy to generate power for us we evolved to use create wind and propulsion by providing power to drive the same thin in reverse.Using the sun for power other by using a mirror was seen as witchcraft throughout history, then we got solar cells...Same for heat in the form of peltier elements and other things...Why then should magnets be any different??Just "Because it is so!" did not work for wind, water and solar, not even for heat....All it takes is a little notch in the right direction to change the way we think about magnets.We have no problem using electromagnets to make a motor spin.We have no problem using magnetic field of any kind to drive motors or generate electricity.We even fail to have a problem by manipulation electromagnetic fields for that purpose.But we struggle like an ant in sand hole to reach the surface again to see what is outside our trap before something grabs us from behind when it comes to permanent magnets.Even worse if you dare to claim your magnetic machine delivers a higher output energy than what you use to make it run.And wasn't it exactly the same ignorance and manifested "knowledge" that got revised so many times throughout history already?Again: Why should magnets or their understanding of interaction be any different?If you follow the above with just matching magnets and the core cube then the result will be at least very surprising to you.Allow this surprise to be an inspiration to improve instead of seeing as a proof of failure ;)And if you made it then please post about it here.Let me know what disappointed you with the outcome.Let me know what really got you wondering.Let me know if you found a suffiently strong north pole to rival the impossible southpole! ;)Start sharing, make other people wonder and make them share it to, let us go viral!The first to post a conclusive Youtube video with results is certain to get a lot, lot, lot attention....

Beware of the new Email scam!

Recently I noticed that one my Emails accounts got some unwanted attention.Both in the standard folder as well as in the provided spam folder I started to collect Emails.And I don't always mean from senders I knew or webistes I am registered with.My usual approach is to just delete what comes from unkown senders or has a suspicious feeling to it.So no winner got it all crap, no offers, no invitations...A few however seemd to originate from some well known "things on the web" - and some of them I am registered with and get ads, offers and such.Sadly that resulted in some Emails being looked at and then discarded anyways.I kept deleting those unwanted mails without opening them for a few days.They they magically changed ;)Websites I used and especially those that require login details appeared as senders.Nothing with any vital info in the preview but also no real activity from my end on those websites.Then I made some impulsive buys on Ebay :(On top of the usual Emails I also got some "reminders" and "seller offers" added.Never happened before and certainly not activated in my Ebay account as feature.And unlike real Emails from Ebay there was my account name missing.Instead a conviently placed and highlighted shortcut button to "You account login" was provided.Ok, fake, forwared to Ebays spam team and quickly confirmed as spam.Moved and only hours later I got more Emails with similar tempting offers as buttons to confirm something that requires me to login.And now from websites or services I actually logged in to this day.The wise donkey said: You have something on your computer that shouldn't be there!Reboot from a CD to have the hard drives checked for malware - negative captain :(Ok then must be something within Windows, time to use a system restor point for a few weeks ago.Again nope...So I used a different browser and quite few websites and services that require my login details.No new Emails... with those websites.Kept using this brwoser for a few days and only stuff I already had cam again a few times but overall far less spam mails.Used the standard browser for a few hours with some login requirements and within a day I had corresponding Emails for a few of them.Found several bad tracking cookies in my browser.Bad in terms of redirecting all visited IP addresses to some addresses I can't even find.Deleted all cookies as well as the browser history.Reboot...A closer look at those suspicious Emails revealed that some include a thing similar to the old single pixel tracker.If you open them and not otherwise prevented it will result in some webservice knowing you actually opened the Email.Together of course with your Email address.The headers were good fakes too so the real sender is properly disguised.Those bottons and links mostly went to websites my browser protection already knows and prevents.Some however did not.In a sandboxed browser I was able to get onto some more or less convincing copies or the originals websites login page.The addressbar always started with originals name but then had a lot of cryptic stuff added to it.Sandbox blocked all what would otherwise make it throughcame through but the browser was rendered useless in the sandbox after I "logged in".Did another check and confirmed that all links buttons and such on that "infected" website also cause the same browser crash.Only difference was that only WITH something typed into the login field the browser tried to establish a new outgoing connection before getting dusted.Conclusions:The malicious Email provides the IP address used.Most if not all links within such an Email end on malicious websites.Some, especially at the beginning don't!!Instead the links go to websites that use cookies and other stuff normal protection mechanisms overlook.Somewhere between opening the link and closing it or the browser a change is made.Either you get a popup windows looking like some advertisement or when you start your browser the next time you see some website added that was not there before.The spammer now know you actually bothered enough to follow at least of the faked links provided in the Emails.The added bonus tracker provides ongoing supplies of websites you visit.A lot still use things in the address bar that identify them as a login page, even if it just starting with HTTPS.Popular websites and services get faked copies on servers in the dark web or at least outside normal DNS services.Now the spammer adds more and more Emails faking things you login to when using a browser for it.Until now nothing too bad or irriversible happend.But get fooled and actually click on a link in one of the new spam mails and it might be over.In the "best outcome" you would be locked out of your browser and have to delete it in safe mode or attempt a manual removal of the hijacker.A bit worse is if your protection started to fail and instead of the hijacke you end up with something manipulating your system.Really bad would be if you end on faked login website, and safety fails until you are locked out from your own system.Don't know what Email you might get after that and what demands to fix your system...However it gets worse: Like the one before but when enter your credentials and hit the login button the website jumps to some random Youtube clip or Goole search page.In case you wonder: You just gave the spammer your personal login details for said webiste or service....Most "deadly" would be if you end on more than just one like that.Every single one give the spammer a new login that you might pay for or that includes even more senstive data.Having to format and re-install all sudden is a thing of far too late then.I do not know if there was an Email I clicked on first, an infected advertisement or even some leaked Email addresses including my own on the internet for sale.All I know for sure is that those tracking options in the malicious Emails correspond to tracking stuff in the browser.No virus, no real malware until you click on the wrong stuff.Anything to prevent this from happening?Whatever you do: Do not use anything that requires the internet! - Just kidding!! Relax...1: Never click on anything inside mails from sources you don't fully trust! If in doubt copy and paste the link into an editor and check if it identical to the real address! Usually you would find some random stuff after the dot of the address name where you would other wise see .COM or .COM.AU.2. In case you ended on some spam or fake looking website anyways you should delete the cookies and browser history. The history might not be required though.3. Best would of course be to only allow known and trusted cookies or to not use any that survive a restart of the browser.4. Very important! If you start to get those Email very shortly after using it to create an account for something on the web then please provide the website you registered at with that Email address !!!5. If you get faked Emails for things you are actually registered with then please consider to imform the admins or support of this website about it. You might not have clicked on it but some user there might if nobody places a warning ;)What if all went to a total failure?I assume why you made that backup of all vital data and kept it updated?Also how install your operating system, in my case Windows, again.A hijack is easy, a fully infected or even encrypted system not.

Embedded printing

Some time ago I made a short Instructable on some basics of integrating other things with a 3D print job.I found some more uses that are not always conventional so to say.For example using an acrylic plate as the "bottom" layer and printing the rest around and on top of it, like a box with a clear bottom.Another nice thing I found is that quite often overhanging parts like hook type hinges can be avoided.Especially if said part needs to be really sturdy one could print it turned by 90° and with some support like an undercut add it to the print.Works really nice too is you want to have movable parts within your printed creation.I might have to do some print jobs next month and was wondering if I should add some more for another Instructable with proper instructions and examples?Anyone done some embedded printing based on my last Ible about it?

Flexible arm material

I'm looking to make a flexible arm that I can position however I want. I need it to have a fair bit of holding strength in that I don't want it to sag. It doesn't need to hold my body weight or anything like that and it can vibrate or move a little without being a problem. Immediately, two things come to mind: the plastic pieces used for coolant in machine shops that has now become a common material for something like this. The other is made up of stacked plates with a ball on one side and a socket in the other, I wire or something of the sort is put through it and a tensioning knob is used to pull it tight and keep it in place. Commonly, I see these in mag base indicators. I'd prefer to find the second one. Though, I can't seem to figure out what to look for in order to make my own. The best thing would be to find a modular kit that would allow you to make one fo any length (I need one that is about twice as long as a mag base indicator mount). Any thoughts on what or look for or anyone know where you could find something like this? P.s. this is going to be used as a way to hold a small screen. If it works well, I may adapt it to work for other things.

A couple of suggestions for the website

When I click on an article in the email and come to the site, it looks as if I'm logged in but nothing works because I must log out and log back in to make the site recognize me. The email click should bring me to a login page and then take me to the clicked-on article.Also, adding something to a collection is awkward, with the roll-down top bar coming into view only when you scroll down and then stepping through several clicks. Compare how natural it is at thingverse. This is how it should work.

How do I repair my crocs?

My puppy got to my new crocs. They are the kind with a solid top and vents on the side, I wear them to work. They are black, if that helps. The little man chewed little stab-wounds in the tops down near the toes. Is there any way to resurface or sort of smooth them out without ruining them, or is there a (somewhat) easy way to add a toe piece to them that would camouflage the damage?

Portable media build parts question

I'm looking to build a portable gaming and media station but I'm stuck on a couple things and am hoping people here might have some suggestions and/or links. Basically, I bought a large aluminum camera case, big enough to hold a 22" led tv in the lid. I am going to mount the tv in the lid, thinking of just drilling the holes and mounting the tv directly to the lid. Any critiques or problems with that would be nice.Second, I'm going to mount a ps3, a portable media player (think Von Haus) which uses flash drives or portable hard drive via US, and a retropie system. Now where I'm running into trouble is two-fold. One is how to mount the items into the case. Foam would normally work well, but I'm worried about heat reduction, less so for the media player and more for the ps3 and retropie. I'm also worried about having it hardmounted onto the case via glue gun because of any shocks it might get while in transport. I also want to dremel out in the front and the back, and put in ports to be able to connect to an outside source as needed. Basically, I need a number of connectors which mount inside with the port leading out. USB 2/3, HDMI, RCA cable connector (RWY). I can find extension cables, but what I'm more looking for is, say for USB, a male lead on one end to connect to the ps3, and a female lead on the other end which sits inside case but is dremel'ed out to be able to connect a USB from the outside, basically a plate which I can just screw in. Something similar to what you'd find inside a console or similar. Anything which anyone can help with on any of these would be greatly appreciated.

Using a small tube to pump air & water threw the glass bulb.I've tried waiting a day, soaking in soapy water, I tried using a pipe cleaner, (broke the glass), I tried pulling a string with tissue paper, (broke again). Is there a chemical I can use to brake up the paint in the bulb, so I can clean it out with running water later. At the moment I'm trying soaking in peroxide or rubbing alcohol.

Low friction "bearings"

For several of my projects I required some sort of bearing that would not only allow for a minimised free play but also very low friction.Before you get too exited: This is not a new type of bearing or anthing for heavy duty loads, not even for ongoing use without servicing.I found that even slightly heavier things rotated on makishift bearing far easier if the axle was verticall instead of horizontally.This gave me the idea to try a simple needle-bearing approach.This is how it goes:1. Grind and polish your axle to get a nice needle point - it must be perfectly centered!I prefer to do this with the axle in a fast spinning drill on a fine grinder.The polishing in a simlilar way, but please do not try it with a cloth in your hand on a spinning axle!2. The other part of the bearing is a screw or pin with a punch mark.I grinded and polished a punch for this so it has an angle of 60° and polished it to a mirror finnish.If alignment is of importance then of course the pin/screw must work for this purpose!If in doubt make it spind an use a pencil to get the true center.A drop of sewing machine oil and it spins nice and with very little friction.The key is to adjust the gap(s) between axle and punch mark to next to nothing.You don't want any pressure along the axle as you would "drill" a hole into your mounts.And you don't want it too loose to avoid wobble.I hope it might give you an idea for your next project.

Converting a .dwg into a .stl for 3D printing a house design (Converting to watertight mesh/ 3d volume)

Hey you guys,I am hoping to use the powers of a crowd to find a quick answer to my problem. I have the architectural Design (.dwg) of a given house (simple model for comparison attached). I need to convert this into a .stl file, preferrably using Fusion360 or Autocad. (newest Version)I understand that the type of the walls and roof is not a 3D volumetric type or a watertight mesh, so the question is how to get there. (Also: of what type of "structure" are these walls - I mean .. they are 3D?)I am an electronics engineer by training, so my CAD knowledge is rather restricted to PCB design.

A powerful EMP generator, to disable (temporarily) stereos in my neighbors house.

Hey guys, I'm trying to build a portable EMP generator, which will be powerful enough to knock out (temporarily) my neighbors stereo (if he plays it on loud at midnight again). My setup is as follows: 8 330v 160uF Capacitors wired up in series. 8 330v charging circuits for the capacitors with their outputs in series wired to the capacitors through a switch. The 8 capacitors are wired up to a coil through a switch. The coil is made from 6 gauge wire (or a 1/16" copper strip) that is coiled 5 times. I would really appreciate any feedback because this is a fairly large undertaking for me, and i'm kind of nervous at working with over 2000v of electricity. Does anyone know if you can discharge a cpapcitor by throwing it into a swimming pool???

An idea for an alternative cloth wringer

I'm thinking about a new design for a cloth wringer like function. A product that will squeeze your cloth from water. Not pointing out any imperfections from a generic cloth wringer shown in the first picture but its just a thought of designing a new one since some say that the current mechanism of a cloth wringer doesn't do the job effectively or there is a separate need for a bucket for it to be attached. Anyway, the design I'm thinking of is to solve any problems that is experienced by a normal cloth wringer.I'm thinking of a new design that would include a tube that would let you insert your desired cloth and a separate cloth absorber that would absorb the water when you squeeze the tube. A picture of a tube would look like the second picture (taken from the internet, youtube aa product called "Easy Squeezy" by Vitility). However its mechanism isn't the same as the idea I have but its physical appearance is kind of the same. I can't make a new one since I still don't know how it would look like based on the mechanism I have in mind.The Easy Squeezer's mechanism includes two separate tubes and you'll need to insert your cloth inside the inner tube and close it by another tube. Then you'll need to apply a force directly into the tube so you'll be able to squeeze out the water from your cloth. As shown from the youtube demonstration video (Link:https://www.youtube.com/watch?v=--tHZRMjk3Q)Thus, an idea came up and the mechanism I have in mind is you'll need the tubes just like from the "Easy Squeezer" and a separate absorbing cloth (preferrably a microfiber one). Then, you'll need to roll your wet cloth along with the microfiber cloth and insert it into the tube. After you've inserted the two rolled clothes into the tubes the mechanism would allow you to create a twisting force into the tubes and ultimately squeeze most of the water from the wet cloth while preserving an uncreased cloth. Which is illustrated from the fourtth picture. Generally, you can do the twisting yourself even without the tubes but it would take a great effort to squeeze and make it a tedious job when you're going to do it for a large amount of wet clothes. The mechanism I have in mind is for the tubes' ability to translate a larger torque (or twisting moment) into the tubes while only having to exert little force. However, the problem is I don't know how to start in the design. Any ideas and suggestions on how to improve?

Just for fun!

I noticed we neither have a section, nor a thread for fun stuff, so I just made one ;)Let me give you something fun to think about, then you can add more funny stuff so we all have a good laugh :)The invisible man - a really old story!There is a man, thausands and thausands of year old, some even say he is as old as time itself.One day the old guy got really bored and decided to do something new.A few days of hard work and within a week he created the universe and all we know.To make it less boring he also decided to add some humans to it.After all, why would you need a TV if you can have it all life.Not long and those humans figured it all out and were really greatful for all the hard work done.So in return they accepted some ground rules, ten of them to be precise.Big buildings were built and everyone also needed some tokens to show how much he loves his god.Many years later some guy came along and got interested in this almighty guy everyone now called "god"."What does he do?""Oh! He loves you and watches you every minute of your life!""Nice! And what does he expect from me?""Just follow the rules and read his book if you feel troubled.""There is a book too?""Certainly is and you can have one for just 10 bucks.""And who is he and what would happen if I break the rules?""God is all powerful, wise, loving and forgiving but if you break the rules you will end in a pit of fire and pain for eternity!""Oh, that much trouble if I break the rules... Can I fix it if I did?""God always loves you and will forgive you!""Hmm, just to make sure that I got it right, let me sum it all up:There is an invisible guy living in the sky, he watches every single one down here every minute of the day.He is all powerful, almighty, all loving and the most forgiving guy you can find.But he needs money.Why do you collect moneyfor him if he never eats, sleeps, drinks or has any fun and also states there is no need for riches?"

Identify WW1 20mm shell casing?

A WWII veteran friend of mine has donated two shells collected on the battlefield in WWI by his father. Following are some photos of the shells: I have tentatively identified them as 20mm HE shells but would like more information, such as manufacturer and probably use. The first image shows both shells. They are 20mm in diameter, the brass casing is 70mm, the steel casing is 49mm and the head is 25mm. The steel casing shows an A and what appears to be an exploding shell. The other two images are of the bases. The letters at the top appear to be B &S;  but could be something else. I believe this is the manufacturer's mark. The 18 should be the year of manufacture. I have no idea what the 125 on the left means nor the numbers on the bottom which are hard to identify. Any assistance would be appreciated because my friend, who is now 95, would like more information concerning the shells. Thank you. Roger Laplante
