Cyclists....

Just for fun this time!We all love bycicles.Enjoy nature, loose some kilos or just having some fun with the kids.I even like to ride if I find the time and the right weather.But what about those courier riders in the city?Those fitness fanatics riding in a pack of 30 and surprising you on a winding mountain road by fully blocking it...The guy hitting you from behind on the traffic lights because he was only looking on his phone...Or maybe this drunk guy in the middle of the night not even realising that he uses the entire road...What is your worst nighmare experience with someone using just legs to get two wheels moving?And: What is your worst nightmare experience as a cyclist yourself?The guy cutting you off while turning and running over your bike?Someone "accidentally" opening their door when you ride past their car?Or maybe these parks constantly blocking the bike lanes and forcing you to go into the traffic?

How to harness the energy in snow

I found a thread that asked this question previously on instructables but the author wanted to harness the kinetic energy of falling snow, and many of the criticisms involved the unpredictability of when snow will fall.I am specifically curious if it is possible to create a machine to remove snow that uses the energy of the snow itself. Ideally, it would melt the snow and use the water or steam to power itself.The things Canadian winters do to the mind...

ionocraft

For those that know (or those that frequent Google's everchanging homepage) today is Tesla's birthday. Just typing in his name into the instructables search brings up loads of Tesla coils but not much else. Some research into some of his other (lesser known/theoretical) inventions uncovered an idea for an ionocraft, a silent flying craft with no moving parts powered by high voltage. (not the place to debate the origin of the invention, Major de Seversky is credited as the inventor of the ionocraft, I am just regurgitating a thought I had while reading on Tesla)A quick search reveals that not only is it possible to build these simple machines, high school kids build them as science fair projects! Although fascinating, this project is outside the realm of my ability for now (read: until my brain grows). Anyone with an inkling?Seeing how there's no end to dangerous instructables, what's one more? (I'll even go the next step and provide you with some plans)

Electric bike motor help!

Helli guys.. after a long time racing motocross, I would like to experiment into doing an electric dirt bike for myself.. My plan is to find an 85 or 125cc frame with no engine, and build from that.. the biggest question is, what motor could I use that is no less than 15kw, and on the affordable side? I was looking at the Turnigy Rotomax 150cc eqiv. And it has a max power output at 9000 something watts, would that be any good for a motocross bike? Would it burn out quickly since its pretty small? Notes: i am strictly looking for powerful bikes, a 2kw bike is not for me since I am used to overpowered 250cc two stroke hell-born suicide machines, thanks..

Hp or Gateway Laptop?

I want a laptop but there are about 2 that are neck-and-neck in my decision.There's this HP which i really like its design and appearance and also the hardware inside it.http://www.walmart.com/catalog/product.do?product_id=9720310#And Then there's this Gateway which has a tiny bit of more parts like a different graphics card, larger hard drive, built in webcam, and lightscribe (not really concerned about these parts).http://www.bestbuy.com/site/olspage.jsp?skuId=8771297&type;=product&id;=1203815723402And I'm pretty sure i want the HP (more trusted brand in my opinion), but i just want a second opinion.

Cleaning the oil for a vacuum pump

Was too lazy to do an Instructable about it and think a lot of pics or even videos won't help much if you know what I mean ;) Some of us use rotary vane pumps not for the purpose of evacuating refrigeration systems but for all sorts of fun and experiments. This means quite soon or often we face the problem of the oil taking in a lot of water or even worse particles and solvent fumes. I don't know about you but I was getting sick and tired of replacing the expensive oil every few weeks or sometimes even days if something got too wrong. There are many different blends of compressor oil out there that will work very well in our rotary vane pumps. The main difference is whyt the oil is designed for. Some are perfect for aircon systems, others for the work with solvent fumes and there are even those special oils that bind moisture. Unless you really need to evacuted special gases or solvents basically any low viscosity oil will do us just fine! So instead of paying 20 bucks for special compressor or even vacuum pump oil we can select the cheap everyday oil. Well, not exactly... We also want to be able to recycle our oil to save even more money. That means we don't want an oil that binds to water to keep it out of harms way. We also don't want any oil that has special coating abilities for example these oils claiming to reduce wear and tear on your engine. But any other low viscosity mineral oil or if you prefer synthetic oil will do - just stay away from silicone based oils!! If you have not used your pump for a few days you can often see a slude at the bottom of the viewing glass. If the rest of the oil is clear you can simply drain this worst bit and top up with fresh oil if required. This simple procedure saves you a lot of oil already, at least if your pump has some rest every now and then. Once your oil looks wasted it is time for the recycling and cleaning: Release the oil into a high glass jar or these facy spaghetti glasses. Fill with fresh oil and give it a short run. Release this oil as well and wait for it to properly drain. You now have the inside of your pump nice and clean again, time to fill one last time with fresh oil to keep using the pump. The filthy oil we now have in our jar should be covered with some fine cloth or filter paper and placed somewhere warm. After a week or two the oil, filth and water will have seperated and you pump, drain or siphon out the now clean oil for further use. Don't be too exact here trying to get all the oil out, just remove what you can without risking to suck in the filth from the bottom. Simply leave the rest in the jar and add the next oil change to it for the same recycling process. Solvents.... In some cases we will work with solvents and that means the oil might bind to them. Acetone for example is quite nasty here and can change the oil itself by breaking down certain components. In most cases it means the viscosity will be reduced, which is not really too bad for us. What is bad however is the fact that these solvents often refuse to fully seperate or evaporate. Once the oil looks clean do a smell test and if it smells like solvent then for sure there is solvent in it. Next step to confirm is to do a lube test. Simply place on some smooth metal or glass and smear it with your finger - a drop is enough here. If it feels sticky on the surface, gives you a rubber like feeling when sliding over the surface or is far less "slippery" than the fresh oil you also have a problem. I found that filling this contaminated oil into a proper container and applying a strong vacuum will remove all solvent residue in a very short time. Downside is that the oil in the pump is contaminated again, so it pays off to collect solvent contaminated oil seperately and once you got enough for several refills use the pump to get rid of the solvent. When done do another smear and smell test, if still smelly repeat if no longer smelly but still the same bad feeling on the surface: Discard as the oil might be broken down by the solvent.

Ducted vacuum cleaner anyone?

My sister approached me today with the news that her vacuum cleaner went up in smoke.While cleaning out the old rental and with the aim to clean the new home during the next few days.This made me thinking about the the ducted vacuum system that were quite popular around here.Most modern house won't get something like that and for the older ones it means once they fail they stay dead.After all the tenant can buy a vacuum cleaner to clean the carpets...Anyways...I had a look around here and in other places to check on home made solutions of the more modern type.As my sister is allowed some DIY to improve the quite old house I was wondering about installing a ducted vacuum system.Of course there is not much out there, commercially, that would be up to our modern times.Far too noisy, lack of sucktion and despite all totally outdated filter systems that won't keep the turbine or motor clean.Some people however came up with quite clever ideas.For example building your own cyclonic shop vac.Another one I quite liked was was a home made housing for standard drum type shop vac.Apart from the air noise the thing was almost silent.No screaming motor, no outcoming air acting as a funnel for the noise create.The air going in and through the hose was louder then the actual vacuum cleaner LOLI would like to create something similar by salvaging a proper shop vac as a bas for the sucking part.But as it is an old house I would really like a wooden solution to entire housing and casing problem.Not just a screaming thing mounted to the outside of the house....Far less noisy than the donor, cyclonic (proper) seperator and easy to empty.Like place a bag under it and open the bottom easy.Something originally intended for inside use might be weatherproved or placed in a properly covered area if required.Any ideas for the wooden part apart from starting from scratch with 3D models?Anyone here done something similar and willing to provide some feedback on how well it all performs?

Wanting to design a cree led powered dock rechargeable torch running on 18650 cells

Hi all, I had an idea the other day that it would be very useful to have a powerful torch in my van that is kept charging in a dock all the time (as required at least) when the engine is running.I know I can get similar torches that charge via a USB cable, and that I could plug the cable into a cigarette lighter socket etc, but what I would like to do is as follows:Power from a 12v (ignition switched) source in vehicle, to a charging dock.Torch must be powered by 18650 lithium-ion cells (2 ideally).Torch would run a cree (or cree style) powerful LED chip/diode (maybe up to 10w arbitrary power).Torch does not need to have a wire plugged into it, but can be simply placed into the dock after use in order to resume charging. The connector for charging is not important but likely a jackplug type arrangement, or else spring terminals.Housing will be 3D printed, and using a lens from an existing torch (probably).So mostly I'm happy about making and designing this, except that I'm not certain about what setup (either the circuit design if bespoke or what off the shelf module etc) I should use for taking 12v to charge 2x 18650 cells in situ.I have got small USB charging modules already, and I have things like voltage boosters/reducers, and tons of electronic components, but the USB charge module is no use for using with a 12v supply etc, so I'm not sure how to best address this part of the project.If anyone has suggestions on good ways to accomplish this I'd be really grateful, thanks!

Unusual uses for coffee machine cleaner or delimer/descaler

Some people can't be without coffee, and some love to keep thei machines as clean as possible.Teste is all and if is not right the day already starts bad...But what is that stuff really?It needs to be food safe, shall not damage or corrode and part of the machine and of course can't be harful or even toxic.The main ingredient is an acid.Some acids are considered to be very corrosive on almost anything, others can set set organic material on fire and some even etch glass.Limestone, coffee staind and build up as well as most minerals that might build up in your machine magically disappear with just some added water and time.Our candidate is named Citric Acid!Very weak on things we thing about when comes to strong acids but quite powerful on the offending stuff in our kettles and coffee machines.Knowing that means we could abandone quite a lot of expensive and specialised cleaning produduct for a fully natural and harmless alternative.Calcium deposits in the bath clean up really nice and quick with it - but read the warnings and dangers below!Same for long abused toilets as mentioned in my topic about it.Stainless steel cooking pots or pans are still a favourite for some people, the pain of cleaning them once something really burnt on badly not so much.Vinegar is a prefered choice here, if you stand the smell when heating it up.Citric acid can not only provide the same cleaning strength but also deal with the things vinegar can't.In some cases stainless steel can develop rusty pits or discoloration from overheating (not trying to make it glow!).And where vinegar just cleans off the burnt in food, citric acid also clean the steel itself.Up to a degree even badly discolored things come back to a silvery look if you give it some time to work.Ever had some rusty parts and tried vinegar to get them back to bare steel?Coke can add some slight protection by passivating the steel, but like on stainless steel citric acid can do more.Unless highly concentrated and hot it won't really affect and good steel quickly.On the other hand it is really aggressive on impurities, rust and certain hard to clean off residues.Words of warning, wisdom and advise!A little bit of hydrochloic acid in your stomach is not only required but also harmless.You wouldn't want in a concentrated form anywhere on your in you though....The same logic is true with citric acid - you can make some nice artificial lemonade with it to enjoy on a hot summers day.But highly conecentrate or even heated up the story is quite different!Proper protection should be as obvious as proper handling.And mishaps should be dealt with lots of water or baking soda right away.I stress this out as my last example will highlight the dangers of citric acid that are not reall known to the public.And if it is that dangerous for some things or even just one that you should not take the risk with living tissue when dealing with higher concentrations or temperatures.Side effect that could possibly be lethal!Shiny things are nice and even nicer if clean and sparkling.Chrome plating or using chrome even is plastic coatings is still common.A lot of tap and bathware is chrome plated, same for a lot of things we have in our households or tool boxes.As tempting as it might be to use citric acid to clean something that just might contain chrome you should not try it!Chrome is almost all of its salt forms is highly toxic, same for most if not all byproducts of chemical reactions involving chrome.Cirtic acid is extremely aggressive on chrome!The tell tale sign is a discoloration of your solution into a greenish-yellow tint!Another a distinct and really unpleasant smell!Some steels include chrome too, so if you notice a bad smell when cleaning then rinse all properly and using other ways of cleaning the item!Corroded chrome plated parts might benefit from a treatment though despite the risk.Unlike sanding the chrome down and contaminating everything with fine and toxic dust you only need to deal with liquids and breathing protection - doing it outside or in really well ventilated areas is a must do anyways here.Dsiposal of anything that caused a bad smell or yellow-greenish discolartion should be done in a sealed container at your local waste disposal center.Please lable it and and also mention it contains chrome dissolved in citric acid!If you placed chrome plated parts into a solution of citric acid by accident and only realise once the smell interrupted your movie session then first go outside!!!This means preferably every living being in the house!If you have use brething protection in the form of carbon filters but either way try to vent the house first by trying to open what you can from the outside.The removal of the metal and taking the container outside should be done as quickly and safely as possible.Unless you are prepared and know what you so stay outside, call the fire brigade and state what happend!A severe reaction with chrome is nothing you should risk your health for!Never, ever dispose of anything that cause a bad smell or discoloration through drain!Bring to a disposal center and keep possible poisons of of the enviroment!

Ever heard of Ceramicrete, MgO cement, Magnesium cement

Has anyone ever worked with MgO cement?  Where can buy it in US? MgO replaces the Ca found in portland cement. MgO cement makes a concrete that will incorporate cellulose and other organics into the crystalline structure. absorbs CO2 instead of generating it, is an order of magnitude stronger than portland, does not require wetting, and cures in minutes. So basically, you can take some burlap or old blanket and paint this stuff on, then fill the void with straw and cement and make super strong, light and thin structures. I have looked for it locally but it does not seem to be available to consumers in the US, probably because of the lack of sheep crap which is the typical source of Mg. It is amazing stuff. This is pretty much the only article I could find about the stuff: http://greenhomebuilding.com/articles/ceramicrete.htm

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.

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!

Replacement solar light kit?

I have a decorative garden light I am very fond of, but the solar charger/led light  is no longer working.  We tried switching out the batteries with new solar rechargeables but that didn't help.  I'm game for replacing the whole thing, charger, light, sensor and all, but haven't been able to find replacement kits anywhere.  The current unit uses one small solar panel about 3 x 4 inches and two AA batteries with one LED.  Clearly I'm not searching for the right words. TIA

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?

Replace mechanical switch with electrical switch or replay

0I have a remote controller for a portable heater, and working on a small project to be able to control the fan on/off from an arduino with Bluetooh HM-10 module. I thought a solenoid might work by mounting on top of the remote but it doesnt have enough force, I want to remove/desolder the mechanical button and figure out a way to control it without the switch but kind dont really know what circuit I should use, kind of just learning how to use arduino.Images of remote and button traces below.Any idea how I could wire this up to arduino via some switch/relay circuit? Any circuit design / schematic would be helpful(See pics attached)
