Removing hair dryer heating element

Request for help:  Does anyone know how to remove the heating element from a hair dryer to have it only blow cold/cool air?  I've opened it up and there are a lot more wires than I expected.  I have just enough electrical knowledge to be a little bit above dangerous, so I thought it would be best to ask for help.  Thanks!

Help Replace Discontinued Range Hood Vent Fan Switch

The variable speed fan control on my Thermador HT48HQS hood vent does not work and the replacement switch is no longer available.  I'm looking for some help in making a new switch.  The Thermador VTR1000Q motor is mounted on the roof and controlled at the hood with a variable speed control knob. The motor is rated at 115V 60Mz 7.8 Amps. Photos of the switch assembly are attached. From what I understand, the speed control knob is a potentiometer that regulates the speed by proving a range of amps from 2.5 to 8? If I could make a variable speed control that would be great.  But I'd be more than happy to have create an on/off toggle switch or a toggle for low on/off high.  Can anyone help me?

Common water insoluble powders to use as heatpipe wick.

I'm wanting to make a heatpipe which works against gravity and so am looking for commonly available materials to use as a wick. Like a sugarcube on a spoon soaking up coffee. Except that since I'll probably be using water as my working fluid, the wick will need to be insoluble in water, as well as heat proof to a couple hundred degrees. A few things I've thought of to try are flour, talcum powder, chalk dust and sand. Thoughts?

Collaboration opportunity: A request for writing assistance

Hi Everybody!The site admins were recently approached by an individual who wishes to share a project on the site, but is unable to write out the steps due to specific health issues. If you have authored a handful of Instructables yourself and would be interested in collaborating with this person, the task would essentially be to organize photos into steps and type out some details of the project in written form.This is a neat opportunity and something a little different, and we will try to help coordinate as best we can.

My Chemical Romance Update =D

My Chemical Romance will go on a temporary break while they seek inspiration to write a new album."We can't make any more music unless we live. When we get a chance, we're going to get together and do some demos and start rolling. But we're going to take it slow,” frontman Gerard Way said.The band took two years to tour in support of their last album, 2006’s The Black Parade. {Posted from The Star}Things have been a little quiet since My Chemical Romance killed off their alter egos, The Black Parade, back in may at New York's legendary Madison Square Garden venue. However frontman Gerard Way has posted a massssiiiivvvveeee update answering all your questions about the new album, how drummer Bob Bryer is after recent wrist surgery, how guitarist Ray Toro's wedding went, what Frank Iero's been up to with his side-band, Leathermouth, as well as quashing internet rumours that he recently died in a car crash.It reads as follows:"Hey guys, Gerard here... I'm hanging out with Mikey in New Jersey, relaxing, drinking coffee, talking comics, and getting ready to take a drive down south tomorrow. I don't know what states I'm passing through but I know where I'm heading. Don't worry, I've got a the Clockwork Orange audiobook, a Dr. Pepper air-freshener, and a GPS so I don't get lost. We figured by now everyone that's a fan of the band might be wondering what we're up to, what we're planning, so I thought I'd write this letter and fill you all in."We're living, decompressing - The Black Parade took over two years to tour and six months to make so that's a lot of existing in a fictional world, and we're just extremely happy to live in a real one for a while. One thing I can let you know is that we're excited. Genuinely more excited than we have ever been to be in this band, make some new music. And we have ALL been writing new material in our own separate worlds... I started a week after I got home, buying a good rig, an old Jag, and a bunch of pedals- just searching for the next sound."Bob is recovering well from his recent wrist surgery - exceedingly well considering how risky the procedure can be. We're all really happy that when he picks up the sticks again he won't be in the intense pain he was in during the last year of touring. It's going to take him a while to rehabilitate but knowing him, he will most likely be playing the drums before the doctor says it's a good idea. He just loves playing, we all do. Franks on the road with Leathermouth and Reggie and The Full Effect so you should go see them and get spit on. I know Leathermouth doesn't have a record out yet, but Frank gave it to me in Mexico and I can easily say it's my favourite post-hardcore record of the year, so I know you will at least enjoy the songs if you don't know the words."One of the best parts of the last five months was getting to see Ray get married and all of us be a part of the wedding. It was beautiful. I'm not sure where the happy couple is right now but I am sure wherever they are, they are really enjoying it. I have never seen him happier in my life. So we made plans to get together soon and make some demos, see where our heads are at, take it slow. If explosions happen in our heads right away who knows how soon we could have a record out, we aren't in any rush but we get just as anxious as you to find out what the next 'thing' is going to be."So that about wraps it up... I'm glad I could stop by for a chat, I think I will do it more often. I'm writing more comics, writing more music, and missing my wife right now. Oh, and I heard a rumour that I died in a car accident. I didn't."[{Posted from Kerrang!}]

Walker/Rollator/KneeScooter type of DIY varieties for knee problem

Hi I am totally new here but have used the search so need your help. I have knee problems. But needs something other than a standard Walker/Rollator So I looked on youtube and google for kneescooters or rideons and Balance Bikes. The reason is that I need something to sit on. A KneeScooter is ideal for that kind of thing. Them are like a knew walker or knee rollator but one sit on them instead. So why don't I just buy the best of them and just love it :) Well them are on the wrong continent. I live in and are a native of Sweden which is Northern Europe in case you wonder. We don't know about such high tech over here. Sure we have same "assisted" Scooters like you have. Like sitting on a three or four wheel Motor Scooter but electric instead of Gasoline. Heavy things you can not take inside unless you buy the coolapsable that is rather neatly made. Anyway I don't really need motor assist I do have muscles so I can pedal a bike but bikes are not allowed inside the Mall and get stolen outside the Mall. Bikes are frown upon on the communal transport like Bus or Commuter Train and such. A Rollator or a Wheeled Walker is allowed everywhere so what I need is a KneeScooter that looks and behaves like a standard Wheeled Walker/Rollator but that one can sit on and ride like a Balance bike for kids. I can try to link to or upload drawings later how I have tried to envision what such would look like or function. So to conclude. It should appear to the Guards, Security Persons at the Mall like any standard Rollator. But then outside when them look away you touch a few buttons or something and it transforms into this handy BalanceBike but for grownups that allow me to push and kick myself striding or riding along but without pedals or motors. Dimensions maybe at most a yard = some 3 feet length and width maybe at most 2 feet and height adjustable for individual length of legs. So it should change between two positions or functions. Like a Rollator Wheeled Walker and then change to a Balance Bike or toddlers bike without pedals so it should be caster wheel as a Rollator but steerable front wheel as a Balance Bike.

Best Way to make uniform crushed glass at home

I obtained an abrasive blaster and I decided to use crushed glass as the media. I have a steady supply of beer an wine bottles that I can crush but have a slight problem. I am currently useing a capped steel pipe and a baseball bat to crush the glass. The results are anywhere from large quarter sized chunks to dust. I want to have crushed glass roughly uniform in size as well as to be able to make larger or smaller sizes depending on the application (rust, paint, etching, etc). Does anyone know of a way a DIYer could make a uniform crushed glass abrasive to use in a blaster?

Is K’nex Gunning Dead?

I know there are some people still doing it (myself included). Much like potato cannons, k’nex guns have lost popularity over time. It’s really a shame that it’s lost so much popularity. Maybe someone could make a website dedicated to K’nex’ing as a kind of KI mark 2. I really hope that it starts up again (without all the block triggers!) sometime but it seems unlikely.

Homemade Sterno type stuff

I was wondering if it would be possible to make a homemade version of sterno similar to the actual stuff. Heres a bit of info on it "Invented around 1900, Sterno is made from ethanol, methanol, water and an amphoteric oxide gelling agent, plus a dye that gives it a characteristic pink color. Designed to be odorless, a 7 oz (198 g) can will burn for up to two hours. The methanol is added to denature the product, which essentially is intended to make it too toxic to be drinkable " There at least are the components but of course no measurements. And where the heck would I get methanol anyway /shrug Not sure wed really need it anyhow. I thought maybe a vaseline and alcohol mixture might be a good place to start but Im not really sure. Any thoughts?

Very Frustrated - Instructable Won't Publish!?!

Okay, so I'm a professor and I have a nice project to publish.  For a first time user of this site, I'm thoroughly frustrated with the lack of detailed feedback when something is wrong.  I would fix it if it would tell me.  Usually I just walk away thinking that the thing is simply not worth the time, but the reputation of this site gives me repose to try to find out why. My instructable was saved and shows up in my drafts.  Great. I hit publish and it goes to a page to request keywords and category.  Great. I put a minimum of 2 keywords and select a category.  Great. I press "yes, publish my instructable" and the page refreshes, clearing everything I've entered. After doing this ten times with no other results or feedback of what the problem is, I find myself writing this topic in hopes somebody knows why.  Whatever the answer is to this dilemma, its kind of ironic that the instructable site is so lacking in basic feedback when there is a problem.. Oh well, I hope you understand my frustration.

Instructables.com is Celebrating 30 Million Unique Users!

We’re excited to announce that Instructables.com just hit 30 million unique monthly users! Thank you so much for being a part of this fantastic, supportive, and inspiring community. You all are awesome. We are a community of makers, and we’re all striving to improve our skills. What makes Instructables special is that we’re also sharing what we learn, and in the process, we are becoming better teachers. The two things feed off of each other: improving skills and then teaching them. If I break down my build and explain it to someone else after I'm done, it gives me a chance to examine the how and why in my process that I might not have otherwise done. Creating an Instructable for a project is a chance to reflect and improve upon my design. All that is to say that I love the Instructables community, and I think it is making a positive difference in the world. We live in interesting times. As Instructables author Dominik Textor put it, “things you couldn’t find in a library in the past and had to travel far to learn can be learnt now in moments.” Instructables is a repository for a lot of knowledge, and it is growing every day. I can’t wait to see what you make next!

In over my head - pH automation

Hi all,I'm in need of help. Due to my previous jobs and general knowledge a friend has asked me if I could build an automatic pH regulation system that will monitor and maintain two tanks (it sounded easy to me at the time) but I've suddenly found myself out of my depth.Having spent long evenings searching on the web and on here, I've seen a few builds of monitors and a couple of dosing systems but none are just what is wanted as they are only set up for single tanks, or not combined into an auto-doser, or too "over-tech'd" or multi-purpose orientated and I don't have the knowledge to adapt or alter things to my requirements. Plunging straight in at the deep end with no real idea of what I'm doing and can actually be done, I'm thinking I should be able to (theoretically) assemble and program an Arduino controlled system, with the one box doing the job of monitoring and regulating both tanks independently, so two sensors, pumps etc., from what I gather it's by adding different boards to the base unit (I did say I know nothing). I don't need wifi or anything like that, just a simple device with a basic display showing the current values that will sit there and just do the job.I think I have the capability to actually build and program the thing having a background in electrics and a little knowledge of relay control systems - not electronics, I start getting lost just after the transistor/diode level and BASIC is more my programming level (yes, I may be THAT old, but I'm still trying to learn), and so what would really help me is if anyone out there can point me towards a site or pages where I can find the info I need, hopefully that doesn't assume years of prior experience, to either build or adapt something to what I want, or even aim me towards someone who could be able to supply me a design and components list, either for fee or free. Cheers!

HHO generator with iron electrodes

Hello Everyone, I recently found out about Sodium Hydroxide as an electrolyte. I have read that it does not affect the electrodes like salt or baking soda and it does not create any weird gasses like chlorine. The main reason for using stainless steel electrodes is to prevent this corrosion, but since sodium hydroxide does not create this corrosion, can I just use the much cheaper iron or regular steel as the electrode plates? Thanks in advance

The "truth" about climate change - a little story

Global warming, climate change, jelly fish attacks, changed ocean currents...We all know the highlights from the news but what is the real deal behind all of this?It can't be denied that burning fossil fuels with no regrets has an impact on our globe.CO2 and other gasses or elements have been trapped for thausands of years.We release them all into our atmosphere and while doing so keep adding more harmful stuff.So, of course it is easy to say that if we would have nver used our fossile fuels to this extent then our world would be unharmed and a happy place throughout.Even if we would ignore the impossible task of making it where we are right now without having used any fossile fuels: How much would it be different?If we trust the offical climate data that has been collected then it clearly shows a rise in so called climate changing emissions since our industrial revolution started.Be it data from the ice, core drillings or just sample taken from old canyons - the results are all the same.Since the late 1800's there is a steady rise in emissions, CO2 and all the other things we don't really want in our air.And for good reasons all these green advocates try their best to stop us from doing more harm.Since the 80's we started to actually care more, better engines, catalytic converters, cleaning mechanisms for our industiral waste and chimneys.But did it make any change or difference?About 40 years now some countries try hard to do it right, so this must show up somewhere?!Well it does not.You see countries like the US never really cared about climate or the enviroment if there was a cheaper and easier option.Just check how long it took them to even acknowledge that our climate is changing due to our interference...Then there is China and as we have seen with the olympics they literally have to shut down production so you can see for more than a few km...But the same is true for so many other countries.Like everwhere else the industrial revolutions comes sooner or later and as always the cheapest way is done first and for far too long.And with the delay in reactions and consequences it is now certain that the worst is yet to come.Of course there is also another side to the entire story - nature itself.We destroy it where we can to safisfy our need for being cheap.Ever wondered where all this cheap furniture is coming from?Or all the wood used throughout the world?Rainforests are disappearing, flora and fauna is destroyed.In most cases with a lot of fires as it is still the easiest way to clean up when done.Now add the vulcanic eruptions that increased over the past 20 odd years around the world.And if you dare all the bushfires or natural causes.Combined this causes a higher impact than all our burning of fossile fuels - and it adds to the mix.And this brings us back in time.Taking the records of climete conditions all the way back to before the dinosaurs showed us that we had periods of much higher temperatures than what we might see soon.CO2 level at some periods were so high that the earth literally was a green house.So why did we humans amke it anyway onto this earth if chance were so bad?Species adjust, evolve or go extinct, new ones appear...Well, unless you are a croc or so and really don't care about Darvin and evolution ;)Does that mean we are on the way to become a new species?Sadly no, because we are the cause of all our problems.We now use technology and science to adjust nature and the enviroment to our needs.It gets too hot? Well add an airconditioner, will you!?The ground water is too contaminted to drink? Well, why do you think we invented bottled water?!You need room for new homes? Don't mind the flood planes, just drain them and build, there was no flood in over 30 years...See, even if we would go fully green and honur nature around the world from today on.Even if we try to clean up the mess we already created.The effects of what we did over the last 40 or more years are still in progress and far from over.Like a good stew it keep cooking until it is ready to serve.But strenght comes in numbers!Like a virus we keep multiplying even in areas with very limited ressources.After all, we just import what we need..Natural selection is being eliminated so pharma companies can make a living too.From just over 40 years our "natural" life expectency increased now to well into the 80's.You are not fertile? No problem we have means to fertilise your eggs with the sperm from hubby!Already suffering badly from diabetes, asthma or other chronical illness? No problem, have some kids anyway.And just to top it always make sure to avoid natural foods in favour for processed and artificial ingredients.In nature the weak, the sick, the old, the malformed and incapable are a food source.We took this food source away, keet them around, care for them and make sure really everyone has the same chance in life.In life - but not in nature anymore!Social evolution meant that natural selection was no longer a requirement to ensure a strong "tribe" or hunting party.We compensated the drain on ressources and all pharma companies are still very grateful for this.No this is no weird rant on humanity or the idea of some mad person, it is just the naked reality we like to ignore.A horse breeder will not accept a weak and constanlty sick horse for his breeding stock.A broken leg, like for a cow usually just means the animal is put down.Some dog breeders still prefer to cull a few pups just because the color pattern is not nice enough or the ears are too short.Even if you just breed fish you o through all sorts of troubles to ensure you have the best genes available in your tanks.You think this is already going to far with the ideas, I know :(But we have real world examples highlighting the results of the exact opposite: Inbreeding and ignoring the defects in genes and health.The british royal family destroyed the italian and russin monarchies the same was the spanish and protugise, even impacted on the french.In times when there was no clue about genetic defects or deseases that can be dormant in females but very active in males, the british royalty simply kept providing tainted bloodlines to the other royal familes.No offsprings that are male and of good health meant the end of their monarchies.The british survived by allowing the common folk to join the blue blood lines and now it is common in all the monachrchies left in the world.Remove the carries, provide fresh genes to get a better diversity.Really no offence, but just look at Charles and Camilla ;)Jokes aside: the story of the european monarchies shows what happens if things go too wrong.From hunters a gatherers that either kept healthy or died out we eveloved to having a gene pool that is full of nasty surprises.Again no offence meant in any way or to any person!If we compare our world with a big aquarium than it might have eveloved like this:Once there was a bowl full of plants, guppies and lots of other fish and creatures living on each other.Over time the guppies learnt when the feeding times are and made sure they get most of the food.Slowly the other psecies had not enough room and food anymore, only the hunter had a good linving with the huge supply of guppies.Then the guppies managed to reduce the dangers from all predators around and started to really take off.Soon every guppy had only conerns about having a good life and enough food.The waste got more and more, the sick and ill too.The last hunter able to fight them died off as he too suffered from the wasten the changed enviroment and gnetic defects transfered.Now there is little plants left, guppies everywhere, crap everywhere and even those guppies only living a few months still manages to find a partner to ensure their tainted gene pool spreads into the general population.We have no tank owner getting the balance right again, removing the sick and weak, we humans just keep going strong and if the crap pile gets too high we put grass and houses on top of it....We humans don't like to be compared with fish, a virus or any other lower being for that matter.These hings just don't affect or concern us.And anyone who dares to do so anyway has a long list of nasty words thrown at them.Is it because we humans can't tolerate the truth?Or is because deep inside we all know but refuse to think about it?

Project VR6

Hello all, thought id share my progress of my 97' VW Golf mk3 VR6 2.8 to create some discussion and VAG banter. I brought her completly standard and wanted to build a real sleeper for road use and track use that is fast, practical for everyday use and safe for the family. When I got her back in 2009 she was a standard vr6 nothing really special just a well looked after example Firstly I gave her a good clean inside and out along with a service.......and by clean i mean really cleaning, shampoo the carpet, treat the leather, clean out the heater units, remove and shampoo the roof lining, polish and resin the paint, de greese and steam clean the engine bay to name some of the bits ive done. The result was a very clean base "template" Once all was clean and I could see areas for imporvement I began the work, replacing all the bushes, front and rear lower arms, brake lines, discs, calipers, exhaust were the easy steps When it came to the engine itself I did not want to mess about with it too much just improve the BHP and general running of the car as 174bhp from a 2.8 VR6 is shocking. So removed the engine and re conditioned the gearbox and clutch. While this was out I thought it best to also do the pull chain not a big job but much easier with everything out, once back in I still was not finished.... After giving the engine a full service with new plugs, leads, coil pack, oil change, rocker cover, inlet manifold, seals, upgraded air filter I decided to get the car chipped to see what BHP could be pulled out of her. Happy to say with all that work she was running on the first dyno 192bhp a massive improvement from standard 174bhp and all that from just replacing and upgrading some standard old parts with more expensive performance parts. Once the Chip was installed and the guys at the tuning store had done their works she was happily chucking out 216.4BHP With that I was more than happy and the work put in over the 6month period really showed. I then decided to have all but bumpers colour coded and did a few minor tweeks to the exterious to make her a clean standard example... I will add a full list of specs and work done soon, enjoy the pics feedback welcome

I want to know how hard it would be to place a water mister in front of the fan in order to feel like I'm out in a light rain.I found an inexpensive mister on Amazonhttps://www.amazon.com/Instapark-Operated-Gardenin...and I thought of placing an auto rotating (every 5 to 10 seconds) servo on the button. Let's make believe I'm a plant and I'm trying to water myself.How hard would this to be?Steve

The little moonshiner....

Found an old topic that someone reactivated with a reply, so I though I do a new one to make it easier. "Moonshine" can be as tasty as any good spirit from the shops. I have done a few liters back in my days... There are a few things to consider right from the start though. What type of sugar is used, e.g. fruits, corn, wheat, potatoes or plain sugar and water. Equally important is the yeast, some prefer natural fermantation, others use baker's yeast, most prefer dedicated yeasts for wine. Even the water used plays a role in the final taste!Hygine is another thing that many people overlook or neglect. Anything that can grow in a warm and sweet enviroment will grow rapidly! That means if your yeast is not good or fast enough, other cultures can take over and sometimes totally change the outcome and quality. In some cases, like with fruits to the better but usually to the worse. Imagine you want to bake a nice cake with vanilla in it. But since your vanilla stick is already quite old and you stored it together with your garden herbs in one jar.... You get the idea of taste I hope ;) Just go from start to finnish like you would prepare chicken meat together with fish - keep it clean, keep it healthy.The still.... Now, if you trust some old blokes doing moonshine since they were kids then it all sounds so easy. But for the hobby brewer there are now tons of options available. Basic pot stills you can put on your stove, electric ones that are basically just an electric boiler with a cooling tube, tower models with several levels of control or the good old "reflux" still in copper. Why is it important to know your way around stills? Again, if you ask a cook then he will tell you why he uses a certain pot for certain dishes or why he won't work with certain materials. Sometimes it is for taste or ease of handling, often just preference. Lets check the main differences in material. We have the modern stainless steel and the classic copper. Stainless steel is easy to clean, won't affect the taste and won't cause any chemical reactions that would alter the taste of your product. That is true only if you trust the manufacturers ;) To compensate for the problems I will explain in a bit they use all sorts of gadgets. I call them brewing helpers and explain them in a bit. Copper on the other hand is now quite expensive and also deemed to be a pain to clean and sanitise. To be honest: how hard it is to clean a still only depends on the design. If you can seperate it into nice straight pieces with good access you can clean anything. But copper was and still is the prefered option for drinking vessels and cookware in a lot of cultures - and it is coming back into our kitchens now as well. Why is that then? Copper has natural sanitising abilities but also reacts with a lot of chemicals. And since copper is considered to be a "good" metal, these reactions usually happen only directly on the copper. Meaning all reaction products stay on the copper as well. Work with fruits or potatoes and a copper still can look dark black and really ugly when done. Do the same in a steel still and then compare the taste ;) Copper produces a far better taste! Especially sufur based compounds react strongly with the copper but also anything causing bad smells or tastes is reduced big time. To flux, reflux not not to flux at all!? A basic still heats the mesh to a set temperature, a cooling coil or similar lets the steam condensate and the alcohol (and everything else) drips out. More complex models have a more tower like appearance and with that allow for a better temperature control. Here the steam will cool down in the tower and at the right height you have the outlet. Brings a much more refined product. The best is still the reflux still however. Here the steam is allowed to travel further and cool down completely. Only a fraction is allowed to come out while the rest runs back down into the heated pot. From first to last model the quality, taste and purity improve. Lets take a closer look on what actually happens inside a still:Once the mix is hot enough that something can turn into a vapor or gas form it will try to escape. That is why we usually discard the first "head" coming out - it contains the most methanol for starters but also the worst of tastes. Again more on heads and tails later ;)In a simple still all steam produced is now turned back into a liquid.One reason why the alcohol concentrations is quite low, around 40%.But also the reason for the low quality taste that can happen.Even with a generous amount of head removed literally everything that is in the opt ends up in the spirit.A good temperature control is a must have and the less deviation the better.And as with all pots running low, once you are low enough all impurities left in your mesh will be concentrated.If the bottom now gets too hot they release unwanted tastes...We skip the tower models and go right to the reflux as the later is just better and includes all there is to say about the tower models anyway.At least on a hobby level a reflux still already starts with a quite tall boiling vessel.It just allows a better and more evenly heating of the mesh inside.While the bottom part is hotter than the top currents form that constantly mix what is inside.The heat is controlled so there is no real boiling, in the best option so that no part of the pot will go over 85° C.When all is hot enough so the first alcohol could run out the system is actually still closed.All vapour has to run back down the tower - which is why some towers even come with cooling fins...As a result all things with a low boiling point will stay in the tower as vapor and once the still is opened they come out first.The heads can be much smaller then too ;)Since the outlet is set at a suitable height and is naturally cooler than the steam, a lot of steam will condense above the outlet.Much more below it and only a fraction is collected to run to the outlet.That means that once the system has reached stable temps throughout that the tower is filled with ethanol vapour only.And since it is constantly re-boiled and runs back down and up all that comes out is already at quite high concentrations.With a good setup as high as 95% vol.It also means that you can have a great level of control about what exactly ends in your ethanol.Depending on how high the outlet is located a different amount of things that can either bond with ethanol or have a similar boiling temperature will be collected.Sole reason why most simple pot stills are designed to work with sugar and clean water only...When working with fruits as a base you often want quite a lot of the flavours and tastes preserved.Only experience and trying will get you tot he sweet spot where the alcohol content is just right and all wanted flavours are included.Go too high with your quality and the alcohol is too pure, go too low and the taste is bad...Which of course brings us back to why you should take your time before the cooking starts!I know far too many people who have no patience when it comes to the end of fermantation.Some yeast might be still active, far too much sugar left over in the mesh or just not enough care in general...You want most if not all of the sugar gone and used.What is not dead in terms of yeast needs to be dormant due to the alcohol concentration.And that can be the tricky part already!You see, once yeast dies off quickly due to the alcohol only the strong survive.In some cases, especially if you re-use your leftovers often, these few can still be active at over 20% of alcohol volume in the mix.The best option is to have a spare fridge and to put the entire container or drum in there.Let it sit cold for a few days, the yeast goes dormant, all sediments settly down to the bottom as no CO2 is produced anymore.Once all is really nice and clear use a hose or similar to remove the clear content only!Be careful here and once the levels are low use a seperate container to drain off!Take out what you can and if in doubt let what you take settle again for a day or two.Doing this time consuming step will make sure you only boil up what brings you the good stuff.On the other hand, when using potatoes, fruits or such you might have to press the liquid out and and add that to what you drained off already.I prefer to do this first and just put it back into the big drum again to let it all settle together.Ok, you only use sugar anyway but what comes out just does not taste or smell right...Would also mean you only use a basic still...As mentioned before the heads are what contains all the nasties.There are ways to actually measure if there is methanol present but for what we do now this is not so important.When the dripping start use shot glasses or such to catch it.Preferably while watching it ;)Smell what it is the glass when you put the next one under.The first glass should smell quite bad anyways.Quickly the smell in the glasses will change to something more "pure" and alcohol like - now start collecting for use.With a simple but good controlled still you will see the flow increases and levels out at some point.When the volume starts to go down your tails start.It is good practise to now use a seperate collecting vessel for the rest until what comes to fully discard.At some point you will notice the difference between just enough and really good temperature control.In a really good system the flow will go down to a slow drip or even stop.While in a dirt simple one the flow will just slow down for a while and then suddenly start running again.This running happens when the remainig water starts boiling...Keep smelling what comes out and once the taste or smell changes noticably again use a different container to collet what comes out. - This is you first tail collection.What comes out until the smell and taste go bad is your second tail collection - now you can turn your still off for a while.Let all what you collected cool down to room temperature is not already.Check what you collected from the heads, helps to have small jars for this ;)From start to last the smell should get better.If the last two or three collections smeel somehow interesting then add them to your main collection.Smell the first tail collection again - it should not be that bad anymore, especially if you let it cool down slightly open.Especially when working with fruits you might to add quite a bit of this to your main collection.If only sugar was used just move on to the last tail collection.In case you still don't like the smell mix the tail collection together and keep in a seperate and sealed vessel.Those tail collections can then later be used to destill them again (with more tails from other runs) to get a decent cleaning alcohol or something that might still be worth adding in small amounts for a better overall taste.However for sugar only mixes it can be considered to be for cleaning purposes only.What you have now is little waste and a lot of almost good alcohol.It still contains more or less amounts of unwanted things that mainly come from the yeast and their by-products.To "clean" you alcohol the best option is to destill it again - it will also increase the concentration quite a bit.Best option here is to use properly filtered and prefeably demineralised water to get back to a full fill of the still.If your still is quite small and what you collected would make for one or two full fills then go for it.Be warned though that you should not fill it up to the full mark, a bit under is better as the mix now will boil far quicker and more violent.Personally I prefer to have the alcohol conectration in the still at around 205% only.As we already discarded the worst of the worst in the heads during our first run only a tiny amount, like half a shot glass should be too bad in terms of taste and smell.Whatever comes after shall be fine.Again, once the tails start try to be carefull and if you can slow things down a notch.You will see a quite destinct reduction in the flow rate once the tails start - use a new container right away.The alcohol concentration should now drop quickly too as another indicator.If you want just pure tasting alcohol add what you comes out from this point to your tails container for later use as you don't want to drink it.Again, for fruits and potatoes you might want to keep the first bit of the collected tails.You alcohol concentration should now be already over 75% even if a basic still was used.The overall volume you collected will be lower accordingly of course - so don't be too disappointed by the liters you got from the second run.In a perfect world you now would use some nice barrel and let your creation age...But since we do moonshine...There is a chance that even after two runs you still taste and smell things you don't want or like.So if in doubt do it all again and get to 90 or more percent...Either way the final stuff should be now either watered down (filtered and clean of course) to the desired level.How to further improve on the outcome....There are little helpers along the way to get far bette results than without using them.If you check ready to go kits then they often contain specialised yest strains, a carbon mix and some "clearing aids".The yeast part is obvious, although I do prefer life prt wine yeast anyway.Carbon or activated charcoal is used to bind some of the bad odors and tastes the yeast produces.Keep in mind they are designed to work together, unlike using proper wine making cultures.Using power yeasts without carbon always results in a low quality.The clearing aids actually change the acidity levels and cause some things to mineralise or otherwise change so they settle to the ground.But they mainly make sure the yeast is dead.If you only use sugar then these kits are your easiest option and just follow their instructions.For fruits or anything else however you might want to try the slow route and use actual wine making yeasts for a change ;)And of course here we do not use carbon at all as we actually want to keep the taste of waht we use.We already had the proper way of getting the mesh to settle down, so that bit is clear.For sugar only you can now try to run your creation through activated charcaol or just add it and mix it.Let it sit and mix again for a few days.You do not need to filter the black stuff out, just drain it carefully and run the last bit through a coffee filter.Nothing will end in your destilled product.Inside the still you can use ceramic bioling thingies of all sorts.They provide a surface for water or mix to boil on instead of just the bottom.If you can't them for a good price then just use the stuff for aquarium filters ;)As said earlier too, copper is good but most modern stills are made from steel.If you can't find any copper wool pot cleaners you can cut some plumbing pipe into small sections.Inside the boiling vessel they will quickly turn brownish black while collecting bad things.Cleaning is easy with some cirtic acid/delimer/coffee machine cleaner...For a tower or reflux still it really helps to have these copper pads or wool inside for a far greater surface area to aid condensation and slow down the run off.I know how hard it is to get the stuff these days so if no other option use stainless steel ones and only loose the benefit of more cleaning through chemical reactions.Tools that come in handy....Monitoring the sugar and alcohol level to know when the mesh is right is quite obvious.What might not be is that you can correct bad level towards the end of fermentation.Yeast already dying slowly but far too much sugar left? Just add luke warm water to lover the alcohol conectration...Yeast going dormant with low alcohol levels? The sugar might be out so chack and if in doubt add some more.A good stir will help the remaining yeast to get more active in a day or two.So these little glass measuring tools should be put to good use from the start.During the destillation a purpose made overflow pipe to hold your alcohol tester is extremly helpful!The destilled liquid goes in through a pipe or hose at the bottom of the pipe.The bottom is closed, the top open to allow to drop the alcohol tester inside.Overflow or outlet should be just under the rim.During your run you can now see directly how the alcohol content changes.It will stabilse once the heads are finnished and get a slight rise just before it drops during the tails section.Improving basic desing of a basic still...Once you are done with a dead simple pot still and buy a reflux or tower model you might wonder why you did not build one yourself.What looked good on the pics and in the shop turns out to be still a bit away from perfect.The outlet might not have any flow control or is located to low/high.The vital overpressure protection might be missing and the thing sometimes runs out like a garden hose...For the later you can slavage some old pressure cooker and use the weight with the screw in counterpart in the lid ;)A simple hole in the top with flat weight on it works too, I used an old rubber plug from my bathtub one (could not find the purpose made one in time).For the outlet you can cheat a bit ;)Wrapping the tower with some insulating material improves on the heat loss - this helps if the still struggles to heat enough to provide a proper flow rate.Cooling the tower with wet towels, running water or similar well help on hot days or if the outlet is located reall high with little chance to provide decent condensation in the lower parts.How to cheat with the barrel....No matter if you just run with sugar or if you prefern corn, wheat, fruits....For some spirits good taste means good age.And well, good age for commercial spirits usually happens by resting in wooden drums.Oak, white oak, red gum and several other types of wood are used.Some small destilleries even use only locally available wood and won't even tell you which tree it was...Means we have a few chocices if we don't want to stick to the well known classics.But how do we make a barrel ?A good one is not just made from any old wood - the wood needs to be of the right age and moisture.To keep it simple just treat it like your firewood and let it rest for the same time.A good barrel is often "charred" - burnt with a flame or by rolling it with burning charcoal inside.This does two imortant things:1: It provides charcoal to bind remaining bad stuff.2: It releases some sugars from the wood plus resins and othe stuff.Both are an essential part of the final product and aging process!Now it becomes clear why a good sprit cost more than vodka...Using a neutral vessel like glass to age your spirit is one thing, preparing the wood the right way another...You see, size matters here in several ways.Big chunks provide a decent surface are without causing too much debris.The also provide more tannins for the color and more resins and sugar.Smaller chunks provide more charcaol for a higher level or binding impurities.But both will soak up far more alcohol than the correspong barrel size would!Obviously, if you are on a small scale on only got about 5 liters of alcohol to deal with loosing much is bad.The best way to char the wood IMHO is inside a clsed can or steel box.Just a small vent hole and a lot of turning with the right eye for when the wood is charred enough to be black and sealed.Opinions vary here but I use about a cup full of wood per 5 liters of alcohol at around 93% vol.Some goes for the storage, apart from dark some can't really agree here.Tossing and turning is as much prefered as undisturbed resting - take your own pick.The thig I do differently after the filtering off is to re-use the wood that is soaked.It goes into a freezer bag until the next run of the still and then the frozen wood is just added to the second still run to get back the alcohol in it, plus some nice taste and smell :)

"Open Link in New Tab" Issues

When you add a link within an "Ible, there's an option to have it open in a new tab. I like to add links to some of the tools and materials I use, and always check the box for that as I find it a bit irritating when the link takes you away from the page you're on.I recently was looking at one of my published 'Ibles and clicked on a link, but it doesn't open in a new tab. I went into edit mode, checked the open in new tab box, and went back to the 'Ible... same thing.I logged out and tried it again to the same result. Tried it in a different web browser just to see too.If I go into edit mode and check the box, save, go out of edit mode, and back into edit mode, the box is unchecked.Has anyone else had this issue? It doesn't affect functionality very much but is a bit of an annoyance

I need help connecting 2 solar panels in paralel

Hi,I'm new to Electronics but I love solar panels and hiking.S, I bought 2 of these:https://www.tomtop.com/p-l1613.htmland one of this:https://www.ebay.com/itm/Dual-USB-Solar-Boost-DC-D...and I connected them. I cut 2 USB Cables, connected + with + and - with - from each Cable and connected it to the DC-DC booster. The amperage is not doubled and the output Volts are lower than 5V which should be the constant output of the booster. The panels were solar oriented and the output was only 0.02 A with Bright enough sun from those 2 solar panels. The panels separately work fine, it is only when I connect them to the booster that they act weird.Is the problem in booster or is it me doing something wrong?Thank you!

Electrical schematic help/wiring + arduino programming

Hello,first time user here, so i would like to just apologize for the wall of text that's coming up.Im trying to build this little enclosure here https://www.instructables.com/id/Touch-sensitive-... and i have a hard time understanding the basics of the electronic schematic thats invovled, when he shows how to build it. Nor do i truly understand what components are in it, hence why i cannot determine the price of this build (based on electronics). So i was wondering if anyone could lable one component by one for me, aswell as how to connect them all together? so that i could calculate the pricing and see how much it would actually cost. Seccond thing is that i wanted to change it up a bit, and use neopixels, or ws2812b led strips instead with a teensy 3.2 and fastled library code, for that fiery effect. Thought that might look really cool. However im concerned with the power draw of these ws2812b led strips. Getting information from adafruit: 60mah per led at maximum brightness, but thats eye blinding, so a 20mah per led is more logical, as someone with neopixels wouldnt be running full white anyways, and more colorful setup, or patterns. Im able to get 144 led/m quite cheap, but then the power draw of just 1m is a whopping 8.64 A. Which is starting to sound pretty dangerous at 5v. But then again, im not buying neopixels to run at full white brightness, i want the patterns. Im wondering if there is any possibilites to make a admin command or a priority list or something to lower the brightness of the strip entirely without messing up the code? i know regular leds have ir remotes to dim the light. I mainly just want the red flame effect, which is only 20mah at max brightness and a peacefull 2.88 A, but i also want white light + i want the safety of knowing i can supply the strip of the power it needs, just incase. The video with the code is underneath: (code in video desc)and i know 144 leds/m is probably overkill, but then again, im getting them dirt cheap, + it would give off a much better fiery effect than a 60 leds/m or even a 30 leds/m thanks in advance for any replies, and sorry for my wall of text. :)

Need a table top that can push stuff upp in the air

Okay so i need some help with a prop for a photographing stuff in mid air.I need a device (flat surface) that I can place objects on and it will shoot them up in the air.Imagine a bowl of popcorn or a pair of glasses with water in them flying up in the air etc. I will then have sensors that will trigger the camera at the right time. (these devices and system I already have)My dream would be to be able to control this "jump table" device thru a simple solenoid valve. (12v) So my rough plan is to have to sheets of wood 40cmx50cm about 1cm thick.Next is to have a pneumatic cylinder in between these two that will push the top plate up and down.I probably need some sort of guides in the corners of the plates so it moves correctly.The pneumatic cylinder will be controlled by a solenoid valve, the solenoid valve i hope to turn on/off with a 12v power supply. The easiest solution for air source would be a co2 cartridge.But if that's to much pressure for the components maybe a cheaper air compressor in a smaller size is usable ?So what im looking for in general advice in terms of pressure and pneumatic cylinders, which i do not have any experience with.This video pretty much has the basic components i need i guess ?Any general advice what to look out for when choosing components and air source ?Thank you!

Tips or products you recommend for clearing or preventing ice in winter?

My partner and I just bought a house and we're doing some repairs and upgrades. One of the major things I want to focus on is making our front entrance less icy. Most of the time we're covered in snow, but whenever it warms up briefly we end up with an icy disaster on the front porch the next morning. :P Currently, the roof melt runs right off onto our front steps and it's a mess! (see picture for the icicle death trap)I have been using a "pet-safe" ice melt (we have two dogs who are in and out all day) but it doesn't do enough for how much I go through. I still break up the ice in the morning when using the ice melt because the ice builds up really quickly.Are there gutters strong enough to handle heavy snowfall? Some sort of heating element I could install? For reference, I'm in northern CO in the mountains and we tend to get feet of snowfall every winter! I've never lived somewhere with this much snow, but I'm hoping some of you do and can offer some suggestions :D

HP, Lenovo, ... Laptop Bios update boot loop fix

I had to install Windows on an older HP laptop today.And being the nice guy I also updated the Bios to the latest available.Now these Windows tools for this job are great fun, start it, press a few buttons and all is updated.Well, until you realise the thing ends in a constant bootloop going back to the bios update part created on the recovery/backup partition.Going the official way by asking the support is pretty much useless as my searches only came up with copy and paste answers but no solution.Some people got desperate enough to order a new bios chip, program it and solder it in :(But the fix is sooo easy and obvious that it might take a little kick to realise it ;)I assume you downloaded the right tool and bios update.For HP and Lenovo it all comes in one pack anyway.I also assume the tool stated that all went fine and the backup and update were done correctly.Now the boot loop that you experience is actually on purpose ;)You are required to enter the bios - for my HP it is the ESC key, then F10.Here you load the defaults, then adjust what you need - like the boot order.Once you set the boot order to the internal HDD or the OS boot manager you are good to again.I hope that will help the desperate people that got nowhere by trying the support for their laptop ;)
