How to Build a cheap small stone cnc machine?

So here is the thing, I have so much stone on my property that I no longer want to remove and throw them away. I wanted to buy small cube stones so that I can lay a driveway and make paths around.So instead of me going to buy which are expensive by piece and I will need a huge quantity, I am thinking about building a CNC machine that I can use to carve out the stones into smaller cubes until I get enough for my driveway. I have been looking for systems unfortunately these are huge and very expensive and unable to find smaller ones for my needs. I also need to know about the types of drill that I will need for specific types of stones. I need to be able to move the machine around my property instead of moving the huge chunks of stones.Here are some examples that I have been looking around Thanks

Best magnet size to coil size ratio for an electromagnetic generator?

What is the best magnet (neodymium - disk shape) size to copper coil size ratio for optimal electron production per one break/pass of flux lines across coil at a 1/2" distance? For instance, if magnet is 2" diameter what is best inner diameter for copper coil? Best number of windings? Best gauge wire? what are the best specs for optimal electron production before you reach "over kill". I know some things are variable like core material and magnet grade. I'm looking for an all things being equal kind of scenario. Also what would be the best thickness of magnet at 2" diameter? If anyone could point me in the direction of any existing tables or ratio information on this subject it would be appreciated. Thank you.

Interactive Surface creation, minimal implementation

Hey guys!This is my very first post in this awesome community. I am not a native make so please forgive me if I may cause any misundestarning with my post.I stumbled upon this video : https://www.youtube.com/watch?v=lvtfD_rJ2hEI started to thinking about creating a simpler version of this, with someones face as a 3D model projecting. My background is in computer vision, so I can handle very well the 3d reconstruction of someone's face from a 2D image.My problem is that I cannot seem to find a way to create the mechanism that will raise those bars and what those bars are going to be made of. Does anyone has any clue on how to create a simple mechanism with not a very complex design?PS: I can handle very well raspberries pi, motors and software.

Cheap beef jerky

At least around here you will be stung painfully in your hip pocket if you want some half decent beef jerky.For some a snack, for others a survivial pack on long hikes, or just fun to eat....I like to do things differently from time to time and where possible save a buck or two.So a few years back I decided to invest in a food dehydrator that doubled up for other projects.There is a lot of traditional ways of making jerky, from selecting the right meat, over the right cutting down to marinating or seasoning the meat.But I did not find too many people using a dehydrator for the final step.A quick run down on my preparations:Meat cut into thin slices, then strips.Marinating for a day or two then a gentle air dry.Optional because I might be the only one who likes it: Covering with salt for a few hours to get a really salty taste.One problem when using a dehydrator with meat is that things can get messy.You only want to air dry on a wire rack or similar until the meat is semi dry on the surface but not until it already starts drying out.I do it inside and only for about 3 hours or so.Doing it for too long can mean much longer drying times in the dehydrator as a crust has formed on the surface already.To prevent excessive mess I cover my trys with non stick baking paper.This means only the top side will be dried until the meat starts to wrinkle up a bit.I dry at around 40°C and do a quick check on the meat every 30 minutes - each time a different tray.Once the top side feels dry to the touch I turn the meat over.If the paper got quite soggy I give it a quick wipe with a paper towel, otherwise I leave it all on there and hope some of it will stick to the meat when turning it over.Depending on the thickness of the meat the entire process can take 8 to 10 hours, thin slices dry in around 5-6 hours.What is the right moisture content for the finnished jerky?That is a question only you can answer!Some people prefer a mild jerky that is firm but easy to chew.Others, like myself, prefer the jerky bone dry and able to be kept fresh in an airtight container for years to come.I found the best way still is to properly age the finnished product before use.By aging I mean putting into a sealed container to even out the moisture level.Unless you rotate in very fancy ways a multi try dehydrator will always produce some pieces in corner areas that are less dry.The key is to have a large enough container so you can shake it all through once or twice a day and giving it a replacement of the air inside.Really hard and dry pieces will soften a bit while those really soft pieces will give their moisture away.Like this the meat is good for about 2 weeks from the day you dried it.Leaving it open in a well ventilated area with very low moisture level will fully dry the meat while it ages and prolong the best before date.Keep in mind that you don't want soggy meat to start with here, the overall moisture level should be well below 10% in the meat when done.If you fully dry it, especially with a bit of salt in it then the meat last for like forever.A nice way to figure out if the meat is fully dry is a digital scale.Take a sample pieve and check the weight, write it down.Place it in the dehydrator for another 30 minutes and check again.Less weight than before means moisture was lost and the meat you sampled was not fully dry yet.Same weight as before means it is dry.As a final step some people might want to put the meat outside on a sunny and dry day.If you do then please not into the direct sun and with a mesh cover to keep insects, dust and other things away from the meat.Cheating on the softness...Some of my friends like their jerky with a consistency more like chewing gum.Or like a slice of good, smoked ham if you don't like chewing gum.The meat selection and cutting direction are vital here.Think of it like bying a steak, the cheap, crappy one means it might be tough one to chew, the quality cut from the butcher will almost be certain to be a great experience.Sizzle or minute steaks are a quicky way to save some time making jerky but not so good for a nice and soft jerky.Of course, if you are on a budget you can cheat with manual labour and tenderise the meat the old fashion way before seasoning or marinating it.The marinade is another way you can cheat.Meat soaks up the marinade to some extend, especially if you tenderised the meat and got rid of the excess fluid that come out of it.Oil should be avoided for obvious reasons but you might have noticed that some commercial jerky always feels greasy.Plant or vegetable fats that melt below about 45°C can be used in a warm marinade to add some softness and in some case a better taste as the fat binds better to spices and seasoning.The downside is that you also need a drying temperature below the melting point of the fat and that it seals in a lot of moisture, which means much longer drying times.But you get a nice and soft jerky in return.The right cut...When you cut your own meat it helps to know what to look for.You want the meat fibres going in the right direction in your jerky slices!If you take a long piece of sirlion as an example than the fibres will run lenghtwise through it.Since you want to be able to rip or chew a piece off the jerky you want these fibres going sideways through your slice, not lenghtwise.In the sirlion example it means you cut thin slices of the "sausage" and from those you cut the strips.The wrong cut...If your fibres run lenghtwise through your jerky strips it will be very hard to get through them.Not only when you want to rip a bit off but also when you chew on it, it can be a very long chew...Some people though prefer it in short strips that are a bit thicker than usual.Like with tobacco in the old days they chew on it until the taste and flavour is out and discard of the rest.

How to fix Windows 7 laptop after downgrading from Windows 10?

I recently upgraded  to windows 10 to try out the new OS. However I found that I preferred my old windows 7 OS better. Thus, I decided to revert back to my old operation system. I went into settings and under recovery found where it said "Go back to Windows 7" and clicked on it. I let it go about its business and when I come back, my computer no longer starts up. It repeatedly gives me an error along the lines of "The computer encountered an unexpected error. Windows installation cannot proceed. To install Windows, click 'OK' to restart the computer , and then restart the installation." But when I click okay, the computer simply restarts and I get the same message again.  The problem is that I do not have an external backup of all of my files because I did not expect anything like this to happen. If there is any way I can solve this problem without losing the files that I have I am all ears. Please provide any help or suggestions you can as I need to get my laptop up and running again. The laptop is an Acer Aspire 7750G-9807 running Windows 7 Home Premium. Please help, anything in greatly appreciated!

Knotless way of tying a fish hook - how to animate it?

Recently I went to "fishing expo".Down here it is on some lake, freshly stocked with fish and on top of all the anglers you get stands with all sorts of fishing stuff to check out.Weather was not to my liking so I stayed dry under the tends and had some smalltalk.It was not long until I wanted to check some braided fishing line offered at one of the stands.And with nothing bad on my mind I took one of the hooks to test the knot strenght.The guys had a nice rig for it.Little did I know about their teaching intentions, claiming that a lot of people have no clue how to properly deal with braided line.Let's just say their way was way too complicated and time consuming for my liking.On a rocky boat you want to be able to do things quick and easy.It was a line rated for 25kg and with their best know on offer it lasted till 22kg until the line failed at the knot.Asked if I could test my way as I would like to know how the line would perform and my wish was granted.The line failed at 27kg and snapped quite some distance form the knot.....Never mind the 25kg rating....The fellow fisherman around as well as the guys selling the line wanted to know how I did my knot without actually making a knot.What was easy out there tunred into a nightmare at home.I tried my biggest hooks and a camera on the tripod but it is not giving me a detailed enough view of how the "knot" is done.Now I could try to make a hook template from some aluminium round bar and use paracord or a thin rope....Then I found a nice app for the phone that uses animations to teach knots.Is there a simple way to create an animation showing a "rope" and a hook with the required details and motion?Would love to share this way of attaching a hook to braided line in a way that is easy to understand and follow....

How do freezing food/expiration dates work?

There's a supermarket right next to my apartment, so I usually go there once a week to buy groceries for the next 7 days or so. I notice that a lot of food has an expiration date that is not far off, so it feels like I have to hurry and eat all of my meat and fruits in vegetables and then if I'm trying to stretch food for another week, all I have left is rice and some odds and ends. I don't know much about freezing/thawing and what you can and can't freeze. My question is, how can I learn about the proper ways to freeze things to extend their usability and not have to buy food again every week. Any pointers

Making a gamepad with the HC05 bluetooth module.

Hi guys! this is my first post here at Instructables :D I really hope someone will be able to help me! Basically the problem is described in the attached image. To be short, we have: - 1x smartphone (Android) - 1x bluetooth module (HC05 with breakout board GW-040 4 pin SPI) - some buttons and arrows... I've already managed to get the HC05 recognized by Windows as a gamepad (modifying the tag using AT commands). The real problem is that i'm stuck with that. I would like to understand how i can connect some buttons (let's say four) that will actually behave like arrows while playing. As far as i understood i need to use the PIO pins but unfortunately my knowledge stops here. Theoretically the code behind this is simple: when the button is pressed the circuit is close and a signal is received by the HC05 who sends the corresponding command via bluetooth. So if the up arrow is pressed, that pin will receive 1 (closed circuit) and the HC05 will send "UP_Arrow" as an instruction to the smartphone. The problem is how do i write down this code and put it into the HC05? since the gamepad tag is "universal" i guess there is some default code for things like this. I think it's the same thing they did with the MOGA... I also read that i could need a SPI-USB Download (something like this ) to use the BlueSuite, that seems like the software needed for this operation. Thanks for any advice!! P.S.: Some useful links i found while searching.. http://dextersstory.tistory.com/3 http://dextersstory.tistory.com/10 http://dextersstory.tistory.com/11 http://dextersstory.tistory.com/16 http://www.martyncurrey.com/arduino-with-hc-05-bluetooth-module-at-mode/ https://developer.mbed.org/users/edodm85/notebook/HC-05-bluetooth/ https://www.sparkfun.com/datasheets/Wireless/Bluetooth/rn-42-ds.pdf http://cdn.sparkfun.com/datasheets/Wireless/Bluetooth/RN-HID-User-Guide-v1.0r.pdf http://ww1.microchip.com/downloads/en/DeviceDoc/bluetooth_cr_UG-v1.0r.pdf

Hacking An Alarm Clock

My sister (yes, the one for whom I made earrings) wants me to modify an alarm clock to run a small electronic device when it goes off. Preliminary research has given me two methods:1) A digital clock with a 555 timer circuitIn this setup, a 555 timer circuit is used to translate the signal to an alarm speaker/piezo disk into a relay. When the clock goes off, the relay clicks, and any electrical device that is run through the relay has power.2) An analog clock with a transistor amplifierIn this version, the analog clock seems to just have a straight DC output to the alarm. The transistor is used to amplify the DC to drive the motor of a fire bell.Which of these would be easier to implement? The device I am supposed to use runs off of 3VDC, so I was just going to run the power line through the relay or through the transformer.

The risks of DIY carpet cleaning and how save a buck or two....

I am writing this partly because of bed experiences with rental angents/landlords and as a general help.Here in Australia as well as other parts of the world it is common pratise that a real estate agent goes through your rented home multiple times a year to check if you keep it clean and undamaged.In most cases these visits go without any hickup until you move out.At this point agents often try to make your life a misery.Some expect you get the house back to the state it was 10 years ago when you moved - an impossible task.Carpet cleaning is usually done with a rented machine.This mean you pay a deposit for the machine and "rent" is made by the highly overpriced cleaning fluid you have to use with the machine.But more and more people see that a $100 machine from the discounter is a "money saver".So lets start with the main differences between a rented, commercial grade machine and those you find at the discounter to buy.The later comes quite small and in plastic, the commercial one is usually all metal and has huge water and waste tank.And lets be honest here, if a good vacuum cleaner sets you back more than twice what your new floor cleaning machine costs.....For me the real difference is in the sucktion.If you start with 10 liters in a commercail machine then you should expect to get over 8 liters back in the waste tank.The added waste often makes it seem much more though ;)The cheap discounter vesion however often struggles to get half of the water back out of your carpet that it drained into it!This is not only due to the weaker vacuum created but also due to the general design and lack of sealing the area that is sucked up.But during a hot summer week this makes no vital difference as it dries off anyway, or does it?Dryness and contamination....If you wash your clothes than you let them fully dry before you wear them.With a freshly cleaned carpet we often don't have that luxury and if the weather won't play nice you might end with a moist carpet for weeks.A proper wash of the carpet would require that water is actually flowing through the fabric.This is achieved by designing water outlets and sucktion areas to be in close proximity.However, most carpets these days are thin and flimsy, the underlay brings the comfort and often the required insulation from the cold floor.Fun fact: Most quality carpets in the EU come with a rubber or foam like backing which prevents that little spills go through and also leave the carpet basically dry after a cleaning.If the amount of water your machine collects does not get very close to what you filled into the tank then you end with a quite wet carpet and underlay.Cold from underneath and with basically no airflow through it.And if you ever removed an old carpet that was cleaned every few years you do know why you wear a protective suit, gloves and a filter mask on your face....It is simply impossible with a handheld machine to prevent water and contaminants from getting into the foam underlay of US and AU style carpet assemblies.Once fully dry there is little chance for anything to grow, but every time you clean the carpet you add the water required...I had it in two rentals that when I cleaned the carpets with a really good machine that stains from within the underlay came back up into the carpet.A job planned for a day then turned into three days of using heater fans and living in a sauna while washing carpets :(The same is true if you end up with fresh dirt or such on the carpet while it is still moist underneat - it gets worked ino the carpet and becomes even harder to clean.Is a commercial cleaning the better option?Sadly I have to say this highly depends on your agent/landlord and how much time and money you have.In some areas agents simply ignore the law and demand from you that the carpet looks at least as good as when you moved in.And if old stains you did not know about come from the filthy underlay a rented machine can come close to the cost of getting a commercail team in to do the job once you vacated.Either way you get an invoice for the service and a statement about the condition of the carpets before and after the cleaning.These guys come with a big van and before it fires up with water only the vacuum is used.Imagine a monster sized vacuum cleaner head on steroids that connects to an industrial sized evacuation fan in the van.It literally lifts your carpet from the underlay and leaves nothing loose behind.The actual cleaning and sanitation works the same way only with the big difference that the water is sprayed with pressure through the carpet and into the underlay.Final round is done dry and with vacuum only, means the carpets are dry enough to walk on them without getting wet feet.A complete dry state is usually reached within 2 days during the summer unlike rented machines that keep the humidity in your house up and high for about 2 weeks until back to normal.Main benefit of a commercail cleaning is that you won't get any issues with your agent/landlord unless you damaged the carpets or made them impossible to clean - ever dropped an ink jet printer refill kit? ;)If I do it myself with a reasonably good machine or a rented one : Do I have options for the cleaning solution used?Trust me, I had to figure that one out quickly when I moved into my first rental down here.4 bedrooms, entire house with carpet except for the kitchen and wet areas.They appeared reasonably clean at a first look but when I used a UV flashlight at night the story was shocking....In what must have a room for a baby the carpet looked like a psychedlic art impression under the UV light.The living room was not much better.As a result the rented machine ran out of cleaning fluid quickly.Bought 2 bottles that were supposed to be suffient for the house size but if you need several rounds per room.I "finnished" the former baby room and was one bottle down already.Called it a day and in the dark the UV light showed a slithly fades art impression but nowhere clean :(The shop had a heavy duty cleaning solution but I did not consider it with a price twice as high.Instead I wondered what would make my carpet different from my clothes in my washing machine....So I got a canister of Oxy-cleaner - sometimes called nappy soaking powder, or similar.Just make sure you get one that does not foam up too much.I used a bucket to dissolve a good amount of the powder before filling it into the machine - at about 40°C.What ended in the waste tank when using this cheap alternative looked digusting to say the least!With that encouragement I decided to make a new bucket with some added washing powder, just a tablespoon worth or just over.Washing powder for front loader does not foam up much, unlike the stuff for top loader, so choose wisely.That was, all counted, the forth cleaning round for the former baby room but after this the UV light showed a clean carpet that also had nice spring fresh smell thanks to the washing powder.Using the same appraoch of lots of oxy cleaner and a bit of washing machine powder in semi hot water made cleaning the rest of the house a breeze!When going slow with the machine it was like mowing the lawn, it left a clean path behind.Not all carpets might tolerate oxy cleaners though, especially if they are quite colorful, so do a spot check first if you never used the stuff to clean up a little spill of red wine before.And please keep some of the commercial cleaning fluid at hand to give the machine a quick wash through with it, otherwise the shop might ask you if you used non approved cleaning stuff with it ;)Tips for adjustable cleaning machines....Some of the rented machines come with several possible adjustments you can make.In the most basic form you can adjust the amount water used and how strong the machine sucks.Keep the sucktion as high as possible unless you actually want to pre soak the carpet.The amount of water should be adjusted to the type of carpet not to how dirty it is!You want just enough water to soak the carpet without going into the underlay too much.A clear sign of using too much water is if you waste tank is only half full when the water tank is empty.A few of the really good machines let you adjust the distance between the water outlet and sucktion area.In most cases there pre-set to what, from experience is the most commonly type of carpet in the area.Your might be different though...A greater distance means more time for the cleaning solution to do its job.This works especially well for thicker carpets with amount of water turned down to below 50%.For thin carpets a short distance is better as the water does not have to go deep into the fabric.Here you can even increase the water flow for very dirty areas without risking to soak the underlay too much.In either case you should check the machine before taking it home and if adjustable have the options explained to you in the store.Anything for really bad areas?The entrance area is often subject to whatever our shoes collected outside, especially if you have kids or playful dogs.A bit of oil from the road, some sticky residue of something, dust, small gravel and sand....Vacuum out what comes out first, then use a suitable, not too stiff brush if your vacuum cleaner does not have a rotating brush in the head.Use a spray bottle and prepare a solution of warm water with a bit of washing machine powder and a shot glass worth of methylated spirit.Slightly wet the soiled area with the spray bottle without saturating it.Use the brush to agitate the carpet fibres - preferably directional and with even strokes.If they are not wet in the deeper areas spray a bit more.Again: you don't want to soak it you want to wet it.Give it about 20 minutes on a warm day a bit longer if the insede temps are below 25°C.Check with your hand if the area is still wet, the alcohol should speed up the evaporation here.Before it dries up repeat the process and check with a paper towel if it picks up the stains already.If so then run over the area with cleaning machine.Best results are achieved if you manage to get the fibres wet all the way down with the brush and won't let the area fully dry off again after the spraying.How can I speed up the drying time?The only way to speed things up is heat and airflow.If outside humidty is quite high then you will struggle.Even in the summer times the humidity levels over night can get well into or even over the 80% region.Opening doors and windows then to get the carpet dry won't really help you.Best time to clean your carpets is actually at night because by the time you are done the sun is out and the humity levels much lower.On a good day below 30%.This is true even for the winter times.Put a few fans up and make sure the temperatures are well above the 20°C mark.If in doubt you have to turn the heater on.Once the humidity inside is sky high you open up all windows and doors to have an exchange of air.A few minutes suffice here unless there is wind at all.If it is a hot summer day you can of course just let it all open until the sun goes down again.During colder times pay special attention to cold areas, like your toilet, bathroom or in general areas that won't warm up properly.Even if the room was not cleaned the moisture can accumulate here and cause mold and mildew.If in doubt make sure the ENTIRE house is warm enough until your carpets are fully dry again.A humidity sensor or gauge certainly helps, two are better so you can check inside and outside at the same time.

DMX - Append

I have a "Dune" mini DMX controller 54 channel's and a Theatrelight 48 channel lighting board. I have seen some plugins that will merge, 2, 3 or even more DMX controllers on a HTP, LTP and Append. They seem very expensive starting at US$500+ I'm in NZ. It is append that I think I want to do. Say the 48 channel are left as 1 to 48 and the 54 channel as 49 to 102. Is there a cheaper DIY way. OR is it possible to just reprogram the Mini to start from chan. 49. I've attached photos of the circuit board.

Remote controlled Pager/vibrating device-compact and light

I am new to Instructables and was hoping for some help. I have been reading through many posts and projects to find what I need, but still need help. I am trying to build a vibrating remote controlled collar to signal to my deaf dog. I would like something very compact that has a small vibrating motor in it that also works at a small distance, not more than 50 yards or so. I only need one setting, two would be great if possible. I just want a small transmitter, (size of a garage door opener) with a single or two buttons to produce a small vibration, and maybe a more intense vibration, to get the dogs attention when he is not looking at me. From there, he is trained to visual hand signals. Any help on how to build this, and build it as LEAST bulky as possible? I have seen a few instructables I am trying to piece together, but I am not an electronics person, have done a few projects like building an egg incubator...So far I know I need a transmitter and a receiver, a power source, which I was hoping could be smaller than a 9volt battery, and a small vibrating motor, possibly the minidisc or bullet type that runs off 3V? Not sure if that would even be strong enough, but my dog is pretty sensitive. I am not opposed to spending a little money, as the dog collars on the market are either cheap garbage for around $20 or good quality but have way more unnecessary features than I need and cost a whopping $200. Thank you very much!

Cinderblock - To paint or not to paint

I always had this question in my mind.  Was the cinderblock designed to breathe?  In other words do we want the moisture to go from one side to the other in case of cinderblock walls (say in the basement walls?)  Logically, I would think that the answer is that we want to prevent the moisture to go from one side to the other.  If that is the case, why the cinderblock makers do not make waterproof cinderblocks by adding water proofing chemicals during the manufacturing process? I would greatly appreciate your insights on this subject.

Easy Cheesecake recipes

What I make is super easy and simple and no baking required.Ingredients: 1 graham cracker pie crust (You should see it in the bake isle* 2 Boxes of the Philadelphia cream cheese (8oz a box) 1 box of cool whip 1 box of Jello (This goes into the mixture with the cream cheese ; Flavor would be whichever you like, I use the lime.) 1 box of Jello (This goes on top after it settles for a couple hours) 1/4 cup of sugar (Depends on how sweet you want it.) -- Mix the two cream cheese together until it gets creamy. -- When it is soft and creamy add the sugar and mix well. -- Open the box the cool whip, pour the whole thing into the cream cheese mix -- Mix well and everything is incorporated. -- Open which ever jello you want into the cream cheese. (I use a Lemon one and I buy the big packs cause its always on sale. Use half of that Jello mix with a cup or hot water. Let the jello cool before pouring it into the cream cheese I usually let it sit over night in the fridge and in the morning, I would mix my lime jello to pour on top.Pour it in and let it sit for about 3 or 4 hours and TADAADADA, Cheesecake is made! I hope this helps, its a family recipe and I hope I explained it clearly, new to this reddit thing and if you have an question, feel free to ask! Enjoy and have a wonderful party and best of luck to ya in the kitchen! :]

I am very passionate about cooking!

I was always very found of cooking everything about it amazes me and I get very curious and eager to mix and match the ingredients and make something good about it as I belong to an Indian family we love spices and cury and specially non-veg but in USA we dont get all spices which we need so we bring the available ones and try to make something of it which taste like hometown and reminds us of our hometown. My parents love cooking too and when I was 5 my dad told me observation is the best key to be a good cook you first observe how me and your mommy makes the food and then go and try to make some and I was fully into those words after few years my mommy gave me the permission to use kitchen I always tried making something which my parents loved and I started cooking more often and got better by time. It might take some time to be a perfectionist not saying that I'm a one but it will be worthy.If this post is helpful to you in any way I appreciate it alot.

VB6 Christmas Light Controller

I have created a VB6 program that synchronizes Christmas lights to music. It could use some refinements in the program. I have used this program for over 13 years. It is capable of 128 channels, may be more but I do not need any more at this time. As of right now the program loads the sync file first then plays the music. This takes up to 4 minutes to load the music sync file between songs. I would like to read the file as it needs it when playing the music. That way to load time would be almost nothing. These are only on and off (blinky) lights for my display, but that is fine with me. I call this program Rudolf and it works on almost any computer. I have run this on a 166 MHz computer with only 48mb of ram and Windows 98! The program also could some help with the editing feature for the lights. If anyone is willing to give me a hand with this I would be very grateful. I am more than willing to give the source code to any one for free. I plan on using this program for many more years to come. I have tried Vixen, but it stops running after a while. Thank You Ricki

Paver pathway puzzle

Hi all!I'm making a paver walkway from my house to my driveway. Unfortunately, the ground slopes downwards towards my house and i'm trying to make it so the water drains away from my house. So, i would like to make the end on the driveway side be lower (sloped downward), however, if i dig a slope down away from the house.. the ground where the grass is at the driveway end will be a few inches too high there.. and the pavers will look sunk into the ground by the end of the walkway if i keep the paver walkway level or slightly sloped down as well. Does this make sense.. its a math puzzle and it's driving me a little crazy! Anyone have a solution?Thank you!Eecole

​How to add a loud speaker to (the most basic) landline phone?

Hello!How would you connect a loudspeaker to a basic landline phone (so several people can hear the conversation)? (Basic phones don't have loudspeakers, only the one handling the headset can hear). The loudspeaker doesn't have to be super loud, it could be like the ones powered by USB on computers, or much smaller, as far as we could hear the conversation. It's not that easy since theses phone are merely powered by the little current inside the landline phone line. So I guess I need another power source, like a USB charger, and maybe to amplify the sound signal, to use the loudspeaker. I started to learn electronics for a few months, but I have no idea how to handle this problem. Any advice would be great! Thanks for your help!

Other uses for a Caramel Wheel....

I had to clean up large sized decals that used a 3M adhesive.Instead of filtering the solvent fumes with my lungs I decided to listen to the guy in the hardware store that suggested to use a Caramel Wheel instead.Have to say I was very sceptical...Ever had this extra heavy duty 3M tape to get off again??No matter what you try it is a battle of will and endurance...To my surprise using the Caramel Wheel was like using a big eraser on paper.The things rubs over the surface, takes the goo off and leaves a totally clean and stick free surface.What otherwise took me at least a full hour was done in under 10 minutes - great...Once done with the hard work I examined the now well used up wheel.Does not really work as a proper eraser for a pencil as the rubber is much harder.Does not even scratch galvanised surfaces.Does not like it at all to be used on wet surfaces :(It is not just rubber in a fully solid form, more like flaky bits stuck together.First misuse I tried was polishing a piece of acrylic plastic.A cloth or similar always soaks up a lot of the polishing compound, which makes the process costly.Friction was a real issue at first because the wheel just had no grip at all.But on hindsight it helped to spread the compound fine and evenly.When it started to grab I noticed two things.a) The plastic warms up quickly.b) It polishes really good.Downside is that you need a low speed and very little pressure, too much of either and you risk stripping off the surface.Second misuse was on my knife.It is old, it is abused, it is loved tool I prefer, so it does not need to be razor sharp.The burr on the knife edge after sharpening should be removed.Usually I work my way up to 1000 grid, then use a leather strop.Not for this old knife though.In most cases the burr comes off with use.The Caramel Wheel had no problems removing the burr while leaving the edge sharp.And with a tiny bit of polishing paste applied it even managed to produce a extra sharp edge.Last misuse so far was to clean off old silicone from my bathroom tiles.Silicone does not like to stick to silicone!Means when you refurbish for example the silicone around your bathtub it never last long.Chemicals to remove the fine layer of silicone are harmful to say the least.I did not bother with the entire groove, just the outer parts where the new silicone needs to grab.First the wheel slips and slides off a lot but you see how it cleans the surface of the tiles.Then it starts to grab, indicating the tile is clean in this area.Won't do much in the grooves with the grouting though...What I really liked is that the wheel took off what you can't really see.The oily feeling when going over removed silicone was gone, just nice grippy tiles.

Cannot reply to comments from you:comments: reply

This bug has been going on at least two or three weeks. When I get an email notification of a comment, and I hit the "reply" link in the email, it takes me to a web page with a valid-looking box for typing the comment. I type the comment, either in a browser or a smartphone browser, hit "post comment," and it vanishes - without a trace. No way of getting it back. This bug does not appear on other pages, just this one. So replying to comments directly from emails does not work.

how to fix elastic waistband that's too tight?

I have a circle skirt with a wide elastic waistband. Skirt is chiffon and waistband material is velour...I think. Awhile back I cut a hole in the waistband and then cut the elastic in the back and tied the two loose pieces together with string to give me more room but I need to fix that. I want to really fix it not have it tied together. I will doing it all by hand so I need easy solutions. I don't own a sewing machine. You can see that the waistband in the front is flat and in the back its all crooked and soft. that's where i cut it. I guess there's no 'support in there now. I showed the pictures of how I cut the waistband. So any ideas are welcome. get rid of elastic? attach more? use something else to connect it?...ok Thanks...
