diy pool heater

I have tried so many different ways to heat my pool water and have had little luck. One way I did it was to take about three hundred feet of black 1/2" drip line and run it around the pool rim. I supplied cold water from a smalloutlet attached to the return line,using the power of the filtration pump to move the water from the pool through thecoil and I adjusted the flow to about half of the normal, then at the end I had the heated water re-enter the pool. Iwould say the water got to about 100 degrees, by the time it went through the drip line. The problem is that it wasn'tefficient enough to have any real effect on the pool water temperature which stays at about 60-65 even on the hottest days. I live in the Sacramento area of California, and we get pretty hot summers, usually about 90-105. Any suggestions on how I could make this idea more efficient? My pool water temp is always too cold to swim in, and I have a capacity of 12,000 gallons.

The best joke in an Instructable

One thing I like a lot when reading Instructables is how creators give a personal spin to their project descriptions and the instructions on how te make something. Sometimes there is even a small laugh on my face when somewhere hidden in step 9, picture 2 there is a funny joke. I can't help it that I include some silly dad jokes myself in my projects.  The idea of this topic is to create a collection that make you smile. A quest for the hidden (dad)jokes in projects. Which ones are your favorites? Since most dad jokes only work in  context I suggest you only post the link to the Instructable and how hard you laughed about it. Not the joke itself out of context. Then we can all go hunting for that silly joke.

The more natural way of cleaning things...

At my workplace we basically have a specific cleaner or cleaning product for every task you can think of. From glass over stainless to plastics and desinfectants for lots of different surfaces. After a quick look into my cleaining cabinet at home I started to wonder if I am doing something wrong as I only have a few cleaning things for my use. Asking my friends also showed they have a big bunch of cleaning chemicals, plus the bottle of bleach that everyone down here has. So I though: Your grandma only had a few cleaning products and you learned most of things you need to clean from her. Considering I grew up healthy I guess she must have done something right.... Let's clean up with the cleaning myths, shall we? 1. What cleaning chemicals do you have? For quite a few people the list would start something like this: Dishwashing liquid, window, cleaner, bathroom cleaner, soap scum remover, floor cleaner, oven cleaner, several desinfectants.... If that is true for you too than we might be on to something already. 2. What cleaning chemicals do I really need? This is a good question as everyone is a bit different but I assume a healthy household here. Of course we need certain things to clean our various surfaces properly but it is far less than waht you have been told by the TV commercials.... These days we like to think if there is a special cleaner for something then of course we have to use it to clean properly. Unless you have trades people walking through with their wet dogs several times a day and see dust storms at least twice a week you really only need a few things. So let's get to the basics: 3. Old style cleaning and what you need for it - really the only stuff required to keep all clean and sanitised. a) Methylated spirit b) Clear ammonia - cloudy ammonia works too but be aware that the added soap can be a problem that leaves streakes c) Hydrogen peroxide - pool grade to be cheap in the long run d) Orange oil - citrus oil works great too if you prefer a different smell e) Soap - just basic soap, these stinky, slightly yellow and hard bricks - no fancy smelly soap ;) f) Several cleaning brushes but you should already have those g) Windows cleaning tools - the basic microfibre cloth and squeegee will do h) Several microfibre cloths - bigger ones for floors and walls, smaller for windows and the rest I) Yesterdays newspaper j) Baking soda With those few things we have everything to clean whatever comes up and if bought in bulk comes down to a few cents per bottle compared to a few dollars when you buy all the stuff you don't need. Lets figure out what the stuff does and how to use it: 4. Mixing and what to use it for.... The alcohol is a really good remover for everything greasy and also desinfects the surfaces. A quick spray and wipe on your bench is all that you need to remove oily residue or the mess from the kids. Mixed with a bit of soap and water (about 50-50) also removes sticky stuff like jam or syrup. If we use about 50ml of alcohol, 50ml of clear ammonia and 900ml of water we get one liter of really good window cleaner. The modern way is to use microfibre for the cleaning and a squeegee to get it dry, the old way just uses a cloth and then the window is "polished" with some old newspaper. The black ink reacts with the alcohol and form a mild abrasive while the paper soaks up the moisture, the result is a prefectly clean window in under 3 minutes. Orange oil is not only a powerful degreaser but also lifts old dirt or even glue residue. Used directly it will get rid of the remains from sticky tape, stickers and everything that other cleaners fails to get off - smoth surface and non soaking of course. 50ml of it with 50ml of ammonia and 100ml of alcohol per bucket makes a good florr cleaner and your house smells nice when done. Works best if you can use a microfibre cloth or floor wiper to dry the surface with it. In the kitchen we can find a lot of surfaces that are greasy and we already covered that bit, so lets get to the though stuff. The kitchen sink can become dull looking although it is not scratched. This is due to hard water, food residue, soap and other things. Best is of course to wipe it and dry it after use but who really does this every day? A pot scrubbing pad with some baking soda on it does the trick here. Make the pad nly moist and sprinkle the baking soda on it. Rub over the stainless and if too dry add a few drops of water. Once done rinse off and enjoy the difference. For hard to clean or badly turtured sinks you can try a ball of aluminium foil and coke - use it like a polish. The oven is often our worst nightmare. The cooktop is not far behind. But even here we can have a chance to clean without too much hard work or bad chemicals. Of course the best way is to prevent these spills and boil overs ;) For the cooktop some hot water and baking soda will soften the baked on stuff. Simply remove what you can with the hot water and then sprinkle the surface with baking soda. Cover all with the paper towels and if not wet enough add a bit more hot water so all shets are soaked. Leave ove night and wipe clean the next day. The oven is a bit of a problem once the side and back wall are filthy. If baking soda with a pot scrubber won't do the trick get some of these steel pads with soap in it. The soap in them is special in terms that you only need a little bit of water to remove almost anything with them - and they won't scrath enamelled surfaces. On the bottom we often have badly burnt in things that are next to impossible to fully remove. I suggest to cover the same way as the cooktop but also to add some orange oil. Just make a thick paste of baking soda and orange oil and wrok it into the soiled surface. Cover with wet paper towels and leave over night. Now you don't want to flood your oven, so that means you need to use a sponge or thick cloth that is big enough to wipe off the surfaces you soaked the day before. As the orange oil really is oil it pays off to use some alcohol in the cleaning water to get rid of the oil and grease a bit easier. Don't expect to see a clean and shiny surface after one treatment if the oven was badly misused, you might have to repeat the procedure a few times. If in doubt use the soapy steel pads for last clean and before soaking over night again. Three to four treatments are usually enough to clean even the worst disaster that can happen in an oven unless you baked it in for months... 5. Desinfecting and mouldy spots.... As said, the methylated spirit is basically just pure alcohol and kill almost anything that might harm you. But sometimes that just is not enough. And who really wants to spend an hour or longer to clean some mouldy spots in the shower or try to cover the smell by spraying room freshener? As a lst resort for everything I use Hydrogen Peroxide. The supermarket grade is only 3% and usually badly overpriced, so I suggest to get a small canister of pool grade peroxide. Do yourself a favour and ask them to install a tap on it - you don't want to do it yourself unless you already know how bad pool grade peroxide is! For your own safety when handling it I strongly recommend wearing long rubber gloves, nitrile is better but please no latex as it could start to burn when getting in contact with the peroxide. For high grade desinfecting or the removal of mouldy areas I recommend to dilute 1:5, one part of peroxide to 5 parts of water. Only for the mould removal on tiled, plastic, glass or metal surfaces you can use the peroxide pure from the container - but please add face protection when cleaning! Some spray bottles work with peroxide some just start leaking badly, if you want try an old bottle of chlorine based cleaner after really flushing everything out. The peroxide breaks down any organic material it comes into contact with, so not just the mould you want to remove but also your skin or eyes if you allow contact. On the skin you see white areas after contact and they won't go away until all the oxygen in the skin is gone that was left by the peroxide. If you act too late it means you might loose some skin flakes. The sure sign of overlook exposure on your skin is a burning sensation in the area - this only happens when the amount was big enough or your clothes got soaked. On your surfaces to clean you will notice bubbles forming quite quickly - this mean the peroxide is reacting with something, usually organic material. Let it bubble... Once it stops bubbling the surface is either sterile or the peroxide is used up, if it bubbles when adding fresh peroxide onto it then there is still crap left ;) It really helps to brush off the surface after each treatment as a lot of loose material will be flushed out when rinsing off. Once it looks and smells clean again it usually means it is clean :) 6. Special case: Wood... Be it wooden floorboards, furniture or just your chopping board - always try what the manufacturer recommends first! Untreated wood should never be cleaned with anything wet! Sealed wood, like floorboards or things with varnish on it to make it water proof can be cleaned the same way as mentioned above - but I would leave out the ammonia as some wood treatments simply won't tolerate it and might go dull instead of returning nice and shiny - spot testing required if you think you have to use ammonia as well! Orange oil itself makes a great furniture cleaner if the surface is smooth and sealed, but if it is not it means the oil soaks into the wood together with the stuff you want to clean off! It also takes off several paints and types of varnish if you work it hard enough and give it some time, so avoid this and be quick instead of forgetting to finnish the job ;) Always try to wet the surface as little as possible and wipe fully dry as soon as possible! Ok, good start but what is the real benefit? For me the actual benefit is that I know what I am using and exposing myself to. Just reading what is in most cleaning products we find at the supermarket makes me want to clean again after using them, just to remove their residues... I admit it might take some time to get used to mixing and just having a few ingredients for the cleaning but it does work great. Especially if you or your kids are already sensitive to certain chemicals or just of poor health in general you might see the benefit quite quickly. Some people really don't like the smell of ammonia but unless you are sensitive to it there is nothing to worry when using the household grade as we always dilute it down massively anyway. A good way to avoid the worst stink is by mixing it outside with the wind from behind. I won't say that certain commercial products are bad, harmful or not good enough for the job. Some are actually worth to have in some cases but I just say it is better to only have a hand full of chemicals that are not too bad instead of an endless list of things were we don't even know what's inside. For me the best is your surprise when it actually works better than you expected and report your findings here.

Need Help Arduino controlled Stepper Motor Proportional Control

Need help with a basic code I'm trying to make for a personal project, I'm new to Arduino and  I find an example of this type of coding would be useful for me to learn off. Would like to get better at this programming stuff and move on to other types of coding. Looked at the basics via the Arduino website but nothing really covered this method of control. A stepper motors speed can be altered via the use of proportional control. The feedback sensor is a potentiometer, which should tell the stepper motor when to stop.  Here are the basics of what I know the code must contain  Kp = 1;// the gain of the proportional control must contain a multiple factor error = Setpoint -actual position; // provides the error value output = error*Kp; // this will provide the drive for the stepper The stepper should stop when the setpoint value equals the actual value. So the stepper should move faster to its target the further away it is. Using a ULN2004A for the driver and have this setup for the circuit. Any help explaining or showing an example code upon how to accomplish this task would be appreciated. No idea how to make this affect the stepper speed or even do this control feedback. Am in need of some help.

Provide cost estimate at the start of classes?

I love the new classes feature here at Instructables, and have the ambition to complete as many of them as possible. I do have some feedback for them, however, and that is that the introduction to the class should include a rough estimate of how much it's going to cost to buy the various bits needed to complete the class. I've just finished the Arduino class and loved the fact that a lot of the lessons leading up to the final project contributed to the final build, and as such helped keep the costs of buying the materials (relatively) low. The same can't be said for the Electronics class, however, which has different projects to build for each lesson and is working out rather expensive as a result. Now please understand, I'm not complaining about the fact you have to build a project for each lesson. If anything I'm rather enjoying it. But a little heads up of what roughly how much the class is going to end up costing would be a welcome addition. I can see this consisting of two different sums: - the cost of equipment which is needed, but once you have it, you have it for keeps. - and the cost of any materials which will be consumed by the project. I'm keen on moving onto another class just as soon as I complete the Electronics one, but would like to be able to work out which one I should go for, taking things like price into account, before I get started - rather than maybe having to abandon the class because I suddenly find I can 't afford some of the equipment or materials I'll need for it. Thank you

One-Stop Shop for Makers

Hi Everyone,  I'm Sarah Calvillo, a visual artist and interactive designer based in San Francisco. I created Steampunk Mr. Potato Head on instructables a while back.  I recently built the first one-stop shop for makers in the U.S. to find and book affordable studio time. Growing up, I've watched my father build our house from his personal workshop. Living in the city, I've found there is limited space to build my own projects. I wanted to create a platform where you could rent space and resources from your community. Funding this project was a major challenge, so I resorted to bartering design for development services with a friend to build Concourse. It took us a couple months to build and launch the site. My only advice for someone replicating this project like this is not to fear being scrappy or hacky. Build what you can, then iterate on what you've built. As a one-woman operation, I’ve been focusing my efforts on helping the Bay Area to start. However, Concourse is open for anyone anywhere to use. You can either rent out your workshop or rent someone else. Visit us  Hope I can help you continue making a create cool stuff on Instructables. DM me for more information about Concourse. Alright ladies and gents, take good care and thanks for your time. All the best, Sarah

Voice Changer Software Into Voice Changer Hardware

I'm making a costume. It's a cosplay. What I Have: Voxal Voice Changer. I already know it's capable of making exactly the voice I need. What I Need: A way of synthesizing my voice with that voice effect as part of my costume. Is this possible? The voice I need isn't a very complex one, but it's not a simple pitch change, either. All it is is a little flanger and a little vibrato, but so far I can't find voice changer devices that allow this without being hooked up to a smart phone or a computer, nor was I able to find portable voice changers that included this effect. They're all girthy with lights and dials, and that's hard to conceal on a costume. I noticed Voxal has an export voice feature that allows users to create .voxal files out of the voices, so I'm wondering if there are existing voice changers that could have this file uploaded to it some how, or if there is a way to make or modify a voice changer to do this. Let me know what you think.

How can I build a Solar Powered Camera for Car Detection

Hello, I'm looking to build a solar powered camera that detects cars moving past and takes a photo. I've been trialing an off the shelf model that relies on software to detect motion but it does not perform well when the cars are travelling over 15km/h. For this reason I'd like to try and develop a camera that senses the magnetic properties of a car (like traffic lights). I'm open to suggestions but here's how I picture it working: Magnetometer detects car > Micro controller > Camera > Micro controller > 3G/4G antenna > Internet. The system would need to be powered by a battery which is charged by a solar panel. Send me an email and we can chat on how to tackle the project. I work for an environmental consultancy so we can provide you with proof of an internship. Thanks.

I'm open to suggestions but here's how I picture it working: Magnetometer detects car > Micro controller > Camera > Micro controller > 3G/4G antenna > Internet. The system would need to be powered by a battery which is charged by a solar panel. Send me an email and we can chat on how to tackle the project. I work for an environmental consultancy so we can provide you with proof of an internship. Thanks.

Making Copper (II) Chloride From Acid and Copper

Ok, so last 4th I made fireworks for a small- and I mean small- display, and it turned out fairly well. I only had two complaints- a) It wasn't that colorful, as I was only using pine and palm charcoal for color: reddish orange.b)it wasn't electrical, and took alot of visco, as I wanted everything to go off near-instantaneously. Well, I am going to solve problem b by getting e-matches off of Skylighter, but solving a is a little harder. Then, I read that certain copper compounds could be added to create a green to green-blue color in the flame. Well, I like that idea, but I didn't know where to get the copper compounds. So I kinda left it. UNTIL TODAY!I found this page on making copper (II) chloride. Well, it seemed straightforward enough, so I was going to try it. I was only wondering about two things:a) why on the description on this page about it include hydrogen peroxide, but the page does not even mention it?b)is this safe? I guess I should be outside for the hotplate part- I can't imagine boiling/simmering HCI, inside.c) is this even possible? Does it: 1)create a form of copper that could be used with success in pyrotechnics? 2)create copper chloride at all?Any answers are appreciated. Even if they don't directly pertain to the topic, POST ANYWAY! Makes it more interesting.

WImeo is censored in Indonesia

Hi I live in Indonesia and am a great fan of instructables, I recently signed up for Arduino class and robotics class. But turns out Wimeo that you use to show videos is blocked in Indonesia ( to stop people watching porn)  This makes it harder to follow the classes and see results of experiments and so on. Could you also make the videos available on youtube and just put a link in under the videos as that is not blocked here. ? thank you for your attention

how to make a circuit board

Circuit board I need to make a circuit board for a project. It is all 12vdc, I have a 1a fan and a 6a thermoelectric device one setting 1, plus another 6a on setting 2, and a 3rd on setting 3 So 1 is 7a 2 is 13a 3 is 19a How to make the board. Also a second device has the 1a fan plus a 4watt element, plus another 4w on setting 2, plus another 4w on setting 3 So 1 is 1a and I think 0.4a= 1.4a 2 is 1.8a 3 is 2.2a. I think

Looking for SIMPLE LED and Nixie drivers

Hello, I am OK with electronics manufacturing, I can understand most schematics and resistor codes ect.. I am looking for a simple circuit to power 6 nixie tubes via a battery NOT plug in. I know most nixies require 170v, but does this mean I need dedicated 170 for each? or can i build one and power them all - it DOES NOT need to be a clock.. they just need to glow and power..  Also I need a simple circuit to run 6 simple RGB LEDs - no big deal Can any of you suggest some circuits? -Sonny
