Herbst Appliance

-update-cant believe the attention this has got. either way i got my braces off...in august of 2008. Wednesday before school started. Finally.straight teeth finally, and i can eat! so great.either way it still took like 5 or 6 years, too long.Im just wearing an invisible retainer(behind my teeth, its glued in, its just a wire). Cant even feel it.Just think- if you have braces- how good it will feel when you get them off...OK, I have braces, meant to correct the spaces that were in between my teeth, and also, to move my lower jaw forward. I've had them for...5 YEARS! Needless to say, they JUST finished closing most of the gaps(again, after 5 years), and are working on moving my jaw forward. So, like almost every person I see with braces (well, some), I got rubber bands. I actually had a choice between them and the Herbst appliance. I picked the herbst-y thing, but they didn't have a part...so, blah blah blah, long story short, I got rubberbands until the part came in. So the part came in today, and I went for them to put it on, and after about an extremely boring hour, they were on. Anyway, It wasn't until then that I realized what (Insert bad word(s) here) things these were. I can't eat ( more specifically- chew), talk (clearly), or EVEN FULLY CLOSE MY MOUTH!.i hate them...................SO... ...on a lighter note, does anyone here have/had that herbst thing before?Update- I got them off, and I'm wearing rubber-bands now.

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.

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.

Fishing the traditional way

A while ago I had a very bad day of fishing in terms of catching something for my frying pan or freezer.Same story for the old bloke sitting a few meters away from me.So we decided to pass some time with useless chats about our previous record fish we caught.While the old bloke changed bait I noticed that he did not have a hook at the end of the line.....What is that contraption and how do you catch fish with it?Old bloke laughed and said he goes hunting a lot too and always keeps the antlers from deer and such.Instead of a hook he used a round and pointy bar with a little notch slightly off the middle.Couldn't figure out how this possibly could hook a fish, so got a bigger laugh for it this time :("Make a loose fist, put it in and then pull on the line." he said and I was dumb enough to assume it would not work :(Figure it out by getting two bleeding pricks...Fish swallows the "stick" inside the bait and one there is some pull one pointy end will always get stuck.The other moves until there is no room to move anymore and the fish is spiked up for good.Only downside is that one you get a fish too big it might not grab - bad luck then LOLThis approach instead of steel hooks reminded me of the bamboo fishing poles my grandfather used to make.Be it for eel, trout, carp or even from the boat for pollock and sardine - he loved his bamboo.Even made me my fisrt fly fishing rod from a piece of bamboo :)The old guy however had more than hand made rods or horn needles as hooks.When his hands were still as good as his eyes he even made flies from these horn sticks!He explained the process to me but I never had the patience for normal flies and doing this with horn sticks and estimating how big the biggest fish might be while making sure it is neither too heavy nor fails to float...What I really liked about this otherwise wasted fishing day was the stories I got from the old man."You don't need fancy or oversensitive gear to fish, a safety pin and some packing coad do just fine if you are hungry!"Best story was how he caught a 2m gummy shark with a hand line meant to catch some sardines for bait.I could really his 3 hour struggle to get the thing on board LOLWhat are your most successfull old school or just plain weird catches with something a real sports fisherman would not even touch to cast?

Make use of iCamera 1000 units?

I have 3 "iCamera 1000" camera units laying around. I do not have the rest of the security system they are designed to function with, but there has to be some way to make use of them and have some fun. I have lots of cat 6 cable and RJ45 connectors to custom make a cable if anyone has the expertise to figure out how to make use of these. Before posting here, I searched and searched here and on Google but only found information regarding the "normal" application of these cameras..... I was hoping for something more outside the box which is why I am here. I included a front/back picture. Thanks for any ideas!!

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.

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???

Rex C100 temperature controller - changing settings

I recently ordered a REX C100 for my electric melting furnace project. As it came already with a SSR and temp sensor I only added a sensor capable of reading more than 400° of the supplied one. These controller are dirt cheap and have lots of support in the modding community - although you now can get them new in all variations so no more modding required. Internally they run on 12V DC, so even mobile use is possible (but this time after modding). My problem with this controller started with the not included manual. As it is no China clone but an original from RKC Japan, I downloaded their manual and tried to adjust the max temp settings as well as changing to the thermocouple. To my surprise the menus for that simply did not exist on my model. Reading a few more manuals showed that to get to the "initial or factory setup" you need to change the lock code. Here things get confusing: Once in the lock menu setting most manuals state to enter "0000" to activate the hidden menus. (Mine was alreay on 0000) Others state to set the code to "0100". In any case you have to hold the setup key for a few seconds to store the changes and after that hold the settings and shift key for about 5 seconds to enter these factory menus. After being close to send the unit back I tried different code combinations and finally found that "1000" actually activates the hidden menu on my model! But again there was no joy as several vital settings still did not show up. To finally get all settings another step is required: The first item in the hidden menu is "CODE" and it shows as "0000". After changing this to "0001" the setup key can be used to get to the settings to change the max and min temps. Once all this done the controller actually shows the selected sensor and if Celsius or Fahrenheit is used at the start and from now on simply by clicking through the hidden menu with the setup key you can get to the min and max temp settings again. I hope this info will help someone running into the same brick walls as I did...

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?"

Can't edit a collection

I made this collection some time ago. At first, when I tried to edit it, it would open up, but it would get stuck in the loading screen, with the dots moving across. I tried again, the same thing happened. The next day, the same thing happened. Then, a short time later, when I open the editor, the site shows the "404: We're sorry, things break sometimes" error. So now I can't even delete the collection.

Modifying Altec Lancings "Life Jacket 2" Waterproof portable speaker.

So I got one of these portable speakers for work. Works great though it could be a touch louder. It lets you charge your phone while either using Bluetooth or direct aux input. Now there's only one problem/annoyance. Every time you power on/off the device and sync to Bluetooth, this voice confirmation plays this audio file that's much longer than it needs to be. "Powering on! Welcome to Altec Lansing" when Bluetooth kicks on "You are now paired! Enjoy!" when you turn off "Powering off!" Anyway, I was already planning on modding it by adding an amplifier to the Line In, since its much louder when a PC is connected vs a phone. I may also add more 18650's but with 15 hour battery life its not necessary. Unless I plan on turning it into a charging hub for all my co-workers phones or something. Anyway, I am here to try to get some help on disabling the voice, its only really a problem because on max volume the voice is WAYY too loud and usually startles people. Here's a review video that shows all the features. Amazingly I can't find a Youtube video of the Voice Confirmation. Here's the useless manual. Manual I Already emailed Altec Lansing to see if there's anyway to disable the voice. I have several images for you to see. I can grab more if necessary. Alternatively, would I be able to just replace the entire board with another one? Such as, an amplifier, USB charger, 18650 charger, and some hacked up Bluetooth headset (with no voice-confirmation) I ask because I rather like the case for its shock resistance capability, and the control buttons are removable so adding new controls and switches would be easy.

My condo apartment smells of chemicals like paint.

I am living in a condo (apartment Building, 2nd Floor). For the last 5 days my house smells of chemicals like paint or something very close to the paint . In the living room we have small office area with computer and printer where smells very strong. Also this smell is in the kitchen, in the bedroom, all over the apartment. I am the only one that can smell it. It is not paint. The refrigerator works ok, the stove is electric and the furnace is turned off.  The Consumers checked for gas, but there was non. Who should I call in order to come and detect where  this smell is coming from?

Update on International Entries in Instructables Contests

We have greatly expanded the list of eligible countries that can participate in our contests!! To find all the eligible countries see below (Eligibility as of 11/16/2015). A small percentage of our contests will be limited to 14 countries (Limited Contests) so make sure to check the rules before entering. Contests rules will not retroactively be changed. Eligibility as of 11/16/2015 THE CONTEST IS OPEN ONLY TO NATURAL PERSONS WHO, AT THE TIME OF ENTRY, ARE REGISTERED MEMBERS OF THE SITE, WHO ARE AT LEAST THIRTEEN (13) YEARS OLD (FIFTEEN [15] YEARS OLD FOR RESIDENTS OF NORWAY AND EIGHTEEN [18] YEARS OLD FOR RESIDENTS OF GERMANY), AND NOT RESIDENTS OF ANY COUNTRY SUBJECT TO A US TRADE EMBARGO (AS OF APRIL 2014 NORTH KOREA, SYRIA, SUDAN, CUBA AND IRAN) AS WELL AS: BRAZIL, ITALY, ARGENTINA, TURKEY, ROMANIA, POLAND, OR THE PROVINCE OF QUEBEC, CANADA. Limited Contests: Eligible countries include: US, UK, Australia, Belgium, Canada (excluding Quebec), China, Colombia, Denmark, Germany, India, Netherlands, New Zealand, Norway, and Switzerland. ___________________________________________________ UPDATE 7/25/2012: Colombia, Denmark, Germany, India, New Zealand, Norway, and Switzerland are now eligible for all contests!  We've updated the rules to make this clear.  More countries coming as fast as we can. --Christy Broadly, there are two types of contests: games of skill and games of chance. Most of our contests are games of skill because they are judged, but we have occasionally run games of chance (random winner in a contest, random commenter wins a prize, etc..). Both types are regulated, sometimes stringently, across the world. As an independent entity, we may have been violating the contest and gaming laws in every country on the planet except the US. While ignorance of the law isn't an acceptable reason to violate it, I did not spend the time to understand and comply with every country's contest laws. Without locations across the world, the potential for enforcement of laws I didn't know about was low. We are now part of an international company, and the potential for enforcement is real. Complying with laws is not a drag! It's what sustainable businesses that expect to be around for a long time do! If you are upset about this, before you complain here, please write or call your representative, member of parliament, or dictator and ask them to simplify contest law in your country. The easier to understand your country's contest laws, the faster we can open our contests to you, and comply with your country's laws. Remember, obeying the law is what good websites do! Autodesk is not trying to destroy the Instructables community by reducing the number of entrants to our contests; in fact, they're very concerned about the issue. We are trying to make sure we obey all the laws of all the countries where we operate. We are simultaneously working to understand the laws of more countries so we can legally run contests in more areas. The terms and conditions of our contests are now in full compliance with the requirements of the US and Canada, except Quebec. Doing so required many hours of me talking to lawyers, and very large costs. I have sorted the countries we will work on next by where our traffic comes from, and where past winners and entrants have come from. For reference: Top 10 Countries by traffic: US - open UK - open Canada - open (minus Quebec) Australia - open India - open Germany - open Philippines Brazil Mexico France Top 10 Countries by winners and entrants: US - open Canada - open UK - open Australia - open Netherlands - open Germany - open New Zealand - open Argentina Colombia - open India - open The rules for games of skill and games of chance are drastically different. I foresee a situation where there are countries in which we can run one type of contest, but not the other. Since we don't collect your country of residence during registration, our method of determining who is eligible is based on where a winner wants us to ship a prize. Obeying laws is not a drag, but this is a tricky situation. I'll concede that you might view this as a bait and switch: we should have fully understood the contest laws of any country where we wanted to encourage DIY through our contests before allowing entrants from those countries. Instead, we allowed everyone, and now have to pause until I can talk to more lawyers. For that I apologize. Fixing this is one of our top priorities.  Even yesterday, I discussed how to get the UK and Australia added to the approved list, and we'll work from there.

Extemely simple automatic emergency light.

I'd like some help to settle an argument regarding my extemely simple automatic emergency light.According to my friend, who installs emergency lighting, this circuit is too simple and has too many components missing but I say he's wrong, if one part fails it can easily be replaced. I'm not and electronics expert either.I'll explain the circuit...5v comes from a 5v 2A phone charger. Battery is a 32Ah 12v SLA. 12v charger is a smart charger with built-in status monitor.SPDT 5v relay rated to switch 12v @ 17amp maxThe light is a 12v 5 metre LED Strip with built in current-limiters and draws arount 2A.Basically, 5v powers the relay which means the battery is connected to the smart charger that keeps it topped up while there is mains power (240v here in UK). If there is a power cut the relay turns off and battery is switches over to the LED light Strip. Its that simple.It works as designed, no parts have failed and I haven't found any signs of over-heating. My friend believes it should all be one circuit and not seperate parts and is a fire risk as it is.He just won't let it go, so does he have a point or is he just being a/an _________ (fill in the blank, lol)? I've included a schematic of the circuit. Not sure if I've drawn the relay properly though.

Play a Collaboration Game?

Oh my... Coffee beans!.Let's try this again! ..Challenge: Oh my! I lost my precious special coffee beans! I need to travel around the world searching for them. Will you help me stay awake for that? I will need loooots of coffee for my mission ;)Design a new coffee filter! Collaborate and innovate together - find a new way to filter coffee. Do not use anything expensive and try not to create too much waste ;) Let's go!... How does this game work: 1) First collect ideas for a coffee filter here under this thread until Monday, March 04th midnight PST - write down what you think would work, freely. (Add in to the already collected ideas - challenge yourself!)2) Look at and discuss others' ideas here, while they are being collected.3) Select one idea that you like, and form teams - prototype together, form an Instructable, make it Collaborative. Or alternatively, just add in your existing Instructable and make it Collaborative. Innovate together! A very rough prototype that shows the principle is sufficient. The time limit for this step is to be announced - not more than several days. 4) Collect the 'ibles here under this thread (or I could make a collection of 'ibles if possible) 5) Let's vote and see which new coffee filter is the best! Try to win the most votes and be on the 'podium'!...I will always be around here - you could ask me anything and also give feedback :).Disclaimer: This is part of a research for my PhD at Istanbul Technical University, department of Industrial Design. The research is strictly non-commercial, only for academic purposes and not financed in any way. The only objective of this game is to encourage collaboration and innovation in communities, in a playful and fun way.

What is it? Is there a modern equivalent?

This is from a 1949 Pfaff 332 sewing machine foot pedal. (I believe the machine was brought to the US by a war bride.) When I tried the machine recently, it wouldn't completely stop when I took my foot off. We opened it up and found this partially decomposed multi layered 'thing'. Other than dust and dirt, it looks like the only damaged part. Does anyone know what it is? Does anyone know what a modern equivalent would be?

Instructables Joins Autodesk

The Instructables community is incredible: you build, bake, and create amazing things, then share your projects and ideas with the world. I think it’s great when someone builds a project using instructions from our site, but it’s even more amazing when we inspire someone to start (or finish) that project they’ve always dreamed of. This has been my vision for Instructables: to have a positive impact on the world by giving passionate people great publishing tools to document their projects, and connect them to a community full of like-minded people. Today I’m able to share my plan for accelerating that vision, and making Instructables an even better place to be. I’m proud to announce that Instructables is becoming part of Autodesk. Everyone here at Instructables HQ is absolutely thrilled, because this is going to be awesome for the entire Instructables community. Instructables will still be the same site you love: we’ll keep the Instructables name and URL, the whole team is staying on, our policies haven’t changed, you still hold copyright to your projects, we’ll still run awesome contests, and the Robot isn’t going anywhere. However, we’ll now have the resources to make some improvements to the site I know our authors and community will love. Autodesk gives us the scale and support to grow and improve Instructables, build some great apps, and continue our mission of creating a positive impact on the world. Everyone on the Instructables team will become Autodesk employees, but we'll still wear our Robot t-shirts with pride. Autodesk is a great cultural fit for Instructables. They make tools for creative people: they’re the world leader in 3D design, engineering, and entertainment software. Even if you don’t recognize the name Autodesk, their software has powered the movies you watch, and designed the cars you drive and the buildings you work in. Instructables will be the community arm of the same team that makes 123D, SketchBook, Homestyler, and Pixlr, which will help provide creative tools, inspiration, and services for all types of creative people. Here’s Carl Bass, Autodesk’s CEO, talking more about his vision for the future of DIY. We’ve had a great time building Instructables, and look forward to taking it to the next level. Thanks to the Instructables team for all their hard work, our investors including O’Reilly Alpha Tech Ventures and Baseline Ventures for believing in us, and to all the authors and community members who have made Instructables a great place to learn and share ideas. I’m confident Autodesk will be a great home for Instructables, and will help us make Instructables an even better place to share your projects and ideas. I’m excited to join the Autodesk team, and get right to work. I’d also like to hear what you think: click here for info on an upcoming live Q&A; event, and click here to suggest how we should co-opt the resources of a multi-national corporation to make Instructables even more awesome. This announcement is duplicated on our blog here.

Another idea for a piece-tracking chess board

RFID-based chess boards have their merits of course, but would be pretty expensive and could potentially suffer from antenna cross-talk. Furthermore, the relatively immense amount of information carried compared to what's required makes RFID sort of overkill. Reed switches have the opposite problem, only carrying a single bit of information per square (piece present y/n). It seems that what you want is something in-between (six kinds of pieces, two colors, so you only need four bits of entropy per square/piece).My idea is the following:Each square is a circuit containing a signal generator connected to four bandpass filters at frequencies f1,f2,f3,f4 (multiplexed of course, so that we only need a few signal generators/filters)Each piece has a RLC circuit in the foot (with fairly large inductance)The circuit in each piece is tuned to resonate at frequency f1, f2, f3 or f4, or any combination of the fourTo poll a square for information, we mux to the square's circuit and generate sin(f1) + sin(f2) + sin(f3) + sin(f4). Now we should be able to discern which piece is on the square based on the frequency response observed at the output of the bandpass filtersIf I'm not completely missing something, the resulting PCB should be comparatively cheap to construct. But I'd love to hear if this is a less elegant solution than I think. Are there any problems with this idea?

23 stage no-capacitor full auto coilgun

  *********I have updated my design since posting this topic. The video is the more current design than what is written below.**********    I came to the conclusion that using capacitors to provide the power for a coil gun is a stupid idea. A bold statement I know. The reason is that they are big and heavy, take time to charge, and need charging circuits. Also, the sharp rise in current that comes from capacitors is bad unless you are making an induction style coilgun, because the induced currents will hurt efficiency.    If coil guns are ever going to be a practical hand held weapon it will need to be lighter, simpler / less delicate, and more powerful than what you will find on the internet if you look up coil guns. A rate of fire that is competitive with conventional guns will also be needed if a coil gun will be used for anything other than target shooting or maybe hobby hunting. So I designed a coilgun to meet these requirements. Visit my website for a full explanation of the design: http://www.ourbadscience.com/#!em-guns/cwjy     I realized that a coilgun would not be a practical infantry weapon until batteries are more advanced anyway, so that just adds to the list of why capacitors are out. It will be powered directly off of the batteries, and have many coil stages. This allows a very high rate of fire. To get that rate of fire with capacitors you would need several capacitor banks charging at offset times, so after each bank fires another is just finished charging. That would be terribly bulky.    The lower voltage from the batteries will give comparatively slow current rise in the coils which normally would make the coil timing weird. I plan to use an unconventional coil timing though. All the coils will be activated at once, and the coils behind the projectile will be shut off as it passes them. This will have several advantages: -The coils will only be powering up for a split second at the beginning. Most coils will already be at full power when the projectile gets to them (that is not the case in most coil guns). -Induced current will not be any issue. -Since the coils will all act as one coil, the projectile will be drawn toward the center of all the coils that are on. Timing of the shut off of the coils will not need to be perfect.    This will be a pre-tuned passively timed system. I want to use a small adjustable electronic timer for the switch-off timing. This will require some work in the initial adjustment of the timing, but even actively switched coil guns (with optical sensors or something) require that. the advantage of a passive system over an active system is cost and simplicity, and you can pack the coils tighter on the barrel if you are not putting a sensor between each stage. That matters with 23 stages! As I said check out my website to see more details and pictures for this and other projects: http://www.ourbadscience.com/#!em-guns/cwjy

How Do You Make a Clock Silent?

I've tried tinkering, but it never seems to work. Is there a way to make an analog clock silent (or at least quieter), without actually turning it off (the idiot's answer to everything)? I recently had to retire my old bedside clock, and so I bought a cheap-o one at Wal-Mart for about 5 dollars...and it is the loudest thing I've ever heard. Will someone please enlighten me?

What is the most affordable laser cutter for a beginner?

I really would love to try out laser cutting. ..But have no idea what knowledge it requires. I want to be able to design and cut custom wooden puzzle, laser cut fabric and also to cut felt and foam. I would like to start up a small home business. Keeping in mind that I have no clue what knowledge it requires and also know that I have 4 kids and will have to have this machine in my home. I do own a silhouette cameo but unfortunately it does not cut felt or wood. It’s a fun machine for cardstock and all…but nothing heavy duty. So is it safe to have a laser cutter at home with kids?? I mean will the light or whatever that comes off the machine be harmful for my children? Also how much is the cheapest desktop version? Will it be able to cut large fabric? Can it cut 0.5” or 0.75” hard wood?? Would that be pushing my luck?? Please let me know…so I can start saving up for it. I really really love crafting….but availability of items and affordability is a big issue. Thanks!

Want to play a Collaboration Game?

Oh my... Coffee beans!(Sorry - had to create a new thread, would not let me edit)Challenge: Oh my! I lost my precious coffee beans! I need to travel around the world searching for them. Will you help me stay awake for that? Collaborate and innovate together - find a new way to filter coffee! Do not use anything expensive and try not to create too much waste ;) Let's go!... How does this game work: 1) First collect ideas for a coffee filter here under this thread until Sunday 24th midnight PST - write what you think would work freely!2) Discuss the ideas here, while they are being collected.3) Select one idea and form teams - prototype together, form an Instructable, make it Collaborative. Or alternatively, just add in your existing Instructable and make it Collaborative. Innovate together! A very rough prototype that shows the principle is sufficient. The time limit for this step is to be announced - not more than several days.4) Collect the 'ibles here under this thread (or I could make a collection of 'ibles if possible) 5) Let's vote and see which new coffee filter is the best!...I will always be around here - you could ask me anything and give feedback, too :).Disclaimer: This is part of a research for my PhD at Istanbul Technical University, department of Industrial Design. The research is strictly non-commercial, only for academic purposes and not financed in any way. The only objective of this game is to encourage collaboration and innovation in communities, in a playful and fun way.

Why "Vortex" for Vortex math and devices?

If you are new to the topic then it might give you a slightly quicker understanding than watching hours of youtube videos.I assume you have seen these various coils that make a sphere shaped magnet spin at insane speeds.They are a good start.You see by normal understanding these Rodin or Vortex coils should not be able to produce a field that rotates that fast.As with a lot of things we tried to use math to explain it in theory and than adjusted the math to match it.Vortex math was born.So how do you explain blue and red to a blind person that never saw anything?I mean in a way they actually know how it would look if they could see?Doesn't work, but we can use a Dyson vacuum cleaner ;)A lot of "tornados" add up to one giant super tornado.Spinning so fast that "all" the dirst stays behind and only clean air comes out.As in nature all the weather cells add up to one that is more powerful than the combined single ones.The tornados that form the term vortex are around the coils.But also around the entire donut as well as every single strand of wire.In any good vortex the rotational speed increases towards the center and bottom of the vortex.You can try that with some floating stuff when you drain your bathtub or sink.Try to imagine and endless tornado that runs around every wire like a spiral.The coil itself adds another spin vector to it and increases the moving speed or the single tornado.Combined it adds up to a very strong tornadoe moving very fast around in the coil pack.As this also creates a rotating field like another tornado in the donut shape it all gets twisted up.Physics as we know it won't fully explain these effects.Vortex devices that produce electricity are usually coils in a special winding configuration and pattern.Like we try to eliminate certain things with basket coils in the HF area a Rodin or Vortex coil tries to utlise these otherwise unwanted stray effects and interferences.Overunity is another term people like to use here but I leave it up to you if such a things is phsically possible with an electrical system.Vortex math tries to explain all these things demonstrated in experiments.However I found two slight flaws in the common approch.1. Only two dimension used.Unlike the coils the simplified Vortex math only operates in two dimensions.A circle instead of a sphere if you like.2. Again, unlike the coil harmony and resonance are neglected.It seems in some cases people try to draw a circle just with straight lines.While in reality you have a never ending, resonant "stream" in three or to be precise four dimensions.Is it the chicken and egg problem?Yes and no.You can only calculate something if you can fully understand it or exactly replicate it in reality.Vortex coils are just way to interpret theories and get some sort of results.And those results are the real problem.We can measure magnatic fields in strenght and direction even frequency.However we can neither make them visible in real time not measure mixed or entangled fields properly.We "see" Mars is our "red planet" but in reality it just the atmosphere, the surface is not red at all in most places.NASA has enough problems to calculated missions to outer space with enough accuracy.Just imagine they would have to do it while considering that around every path our planets make is another spinning "distraction"....That is exactly what Vortex math tries to do while eliminating common math bit by bit.You can see and hear in 3 dimensions.Maybe you are also good in drawing something in 3D on your compterscreen or 3D headset.But how many here could predict the path of a baseball in 3D like they do when watching a game?Depending on your viewing angle you might be way off....Try to know or calculate where exactly the ball is at any given monet in time and how fast it spins in which direction.....Our brains are not trained to think like this!Even if we construct things like a dome we prefer to have straight features.Sure manufacturing is one thing that needs to be affordable.But try to just calculate the support structure if all is actually fully round like a sphere should be.We avoid what is considered higher dimensions as much we can.To calculate a distance in 3D it still seems easier to use two 2D models to add up instead of true vectors.Again only through technology like computer we are able to simulate, understand and actually calculate what we need.Where we ventured around the globe and into our solar system our math was left behind.Finding workaround and good enough approximations still seems the way to go.Instead actually evolving our math to our needs we just add more and more complex formulas and calculations.To fully understand vortex math you need to let go and start thinking in 4 dimensions instead of just 2.Oh, sorry, you might be new to this...Number 4 is time of course.

Native iOS and Android App Retirement

Hello Community! In an ongoing effort to make sure that Instructables is able to focus its product development efforts where they count most for existing an new authors, we are officially retiring our native iOS and Android apps. Note that this does not affect mobile web. I expect continued investment in mobile technologies for years to come, but we will focus on the experience of people using Instructables through their mobile web browsers, rather than through downloaded apps. For those keeping score, this isn't exactly news. We have not released new versions of either app in over two years, and they have become steadily buggier and buggier during that time due primarily to changes in their respective environments. Android 2 and iOS 5 were current when we released them originally, and Android 7 and iOS 10 are very different beasts. Simply keeping up -- even without adding anything new or fixing any bugs -- requires a constant investment of development time from Instructables, and prevents that time from going to projects with greater impact. The original purposes for the apps were: 1) To lower the bar to Instructables authorship by providing direct access to upload photos taken on smart phones 2) To improve the browsing experience by making it faster Since they were released, mobile technologies have progressed to the point that #1 is no longer a concern. Our mobile web editor already has full support for uploading images directly from your phone. #2 is also coming into striking distance soon, as browser manufacturers begin to standardize their implementation of offline content for mobile web sites, sometimes referred to collectively as "progressive web apps". We'll be watching these technologies closely, and we'll be among the first to speed up your browsing experience with offline components when cross-browser solutions become available. We have already developed (and will continue to expand on) Accelerated Mobile Pages, which mean we display nearly instantaneously when you tap an AMP result on mobile from Google. You can identify these pages via a lightning bolt in mobile search results: In short, the reasons that we developed the native apps no longer apply, and we're dropping support for them in favor of putting those energies where they are able to have greater impact for the community: Mobile Web. The apps will soon be removed from sale from their respective download stores. For existing users who have downloaded these apps and are using them currently: feel free to continue doing so, though we would urge you to upload your Instructable Drafts to the website as soon as possible. While we don't expect the editing process to break, no support is available should you experience issues in the future. You can also use the apps to browse Instructables, though I believe there are already some issues that have started adding friction to this experience. Thanks, all, for your continued support of our vibrant community! ~Devs

How to get an old and filthy toilet back to glory

I moved into a new rental and it was a bit neglected to say it nice.My longest nouisance however was the old toilet.Calcium and urine stains turned the bottom, where the water sits, into a black, crusty mass.Toilet cleaners of all sorts provide a nice smaell, but even bleach or things like jiffy did not do a thing.Hours were wasted trying to scrape, brush or just swear the filth off but no luck.All I managed was to turn the black into a slightly grey crust, still ugly.One day I had the honor to clean my water kettle and to remove the calcium deposits in it.Of course I was lazy and just some delimer, citric acid, as instructed.Let it sit a few hours, wipe it out, nice.Hmmmm.....Hold on a second, what would happen if I use that stuff in the toilet?!?So I flushed some hot water through to warm up the bowl, then about 1 liter of boiling hot water with two packs of coffee machine cleaner dissolved in it.Let it sit over night only to be very disappointed the next morning.It looked like nothing changed.Unlike pots and kettles my toilet appeared to still have al crusts stuck in it.When I flushed however most of it just flushed away!A little brushing and the rest was gone too - a clean and white toilet again!No more calcium and other hard deposits :)

How do I make a power indicater light for a bluetooth?

I have Bluetooth headphones, & I'm modifying them. I want my Bluetooth to light up tow external LEDs when I turn the device on. I can't wire a line to the micro LED, its to small for me to solder. I was thinking wiring the External LEDs to the Bluetooth's battery. Is there a way to make a simple connection from the battery, to the external LED wire & back to the circuit board, so when ever the Bluetooth is switched on, all the external LED is indicating is the power going to the circuit board?

Belt feed

Does anyone have some kide of blueprint on how to make a belt feed MP. I have seen the examples of ones on howstuffworks.com but that isn't helping me much right now. I'm not really sure how I can belt feed it through. I am working with a P.A. Luty's 9mm. Can some one help me on this. If you have been able to make a belt feed system can you show me yours in photos. I think that would also be a great instructable too. I'm not to sure how to make a belt for 9mm rounds either. Instead of sticking with his design on the magazine I think it would be great to have a belt feed system on this weapon.
