Pringles ARE Potato Crisps (Chips)

Procter & Gamble will be forced to pay tens of millions of pounds in VAT after losing a legal battle with the (UK) taxman over its Pringles snack.The Court of Appeal ruled in favour of the Inland Revenue, which maintained that Pringles constitute a potato snack and are, therefore, liable for VAT (tax). The Appeal Court judges disagreed with a previous ruling that the low potato content (42%) exempted Pringles from VAT.See here for BBC article

Tube Material

I started thinking about how the tube material could be improved. Although I love the ghetto look of pringles wrapped in the invincible duct tape, improvements can be made. You could use PVC or ABS for the tube, it wouldnt need pressure rating because Im sure this thing wouldnt have enough power to explode the pringles/tape team. This is rather cheap and you could just glue on an endcap. Then a BBQ ignitor can be threaded in, a ring to define the chamber and barrel and fuel sprayed in! However getting the perfect cost/durability/strength ratio is hard.

how can i un-twist a warping painting on canvas? thing is starting to look a bit like a Pringle. Answered

The stretcher bars are going in all kinds of strange directions and now it kind of looks like something you'd see on a graphic calculator. am i doomed to just restretch it or can i flatten it somehow?

Would this tennis ball mortar design work?

I was thinking about using 3 pringles cans. I'd cut the metal bottoms off of 2 of them and tape them together ontop of the third one, which still has the metal. Then I'd tape/glue a capacitor from a digital camera onto the tennis ball and charge it up. It would hit the bottom, create a spark, and ignite the fuel. Would this work?

Do-it-your-self wireless antenna

Hi,I am new to all this but what has brought me here is my quest to find out how to build a simple home-made WI-FI antenna such as those made out of Pringle tubes or any cheap bits.The sites i have found at the moment do not seem to be clear enough. They also seem to gloss over the main point of how it is actually connected to the laptop I want to increase the signal to. I have a built-in wireless connenction on my HP laptop. Any useful advice, or instructables covering this topic would be very much appreciated. Cheers Muckster

Homemade digital camera telescope adapter

After calling my last diy project a success I decided to give another one a shot and am attempting to make an adapter for my easyshare c813 but all I ever see through the cam viewer is just blackness. I was hoping maybe someone here would have had some experience with this and could maybe point me in the right direction. My adapter so far consists of a couple layers of a pringles can wrapped and tapped with electrical tape inside and out. Ive seen similar contraptions made out of film canisters that work just fine even on webcams but Im having no such luck myself.

I need to make some capacitor?

I need a bunch of high power capacitors and I don't have the money to buy them.  I have a couple ways I have seen and I have done one that kind of works. 2 L bottle - I don't drink enough pop to make enough of these ?pvc? - could I substitute a thin pvc pipe for the 2 litter bottle Leyden jar capacitors - I saw these cool ones that have a tube like pringles uses, al tape around the outside, and then they just push the can into it as the storage. ?pvc? - Could I also substitute pvc for this. Styrofoam cups - I have read about, but not seen this one.  Could I just wrap a cup in foil and then stack it.  Apply positive to top cup and negative to bottom

-Hi dear friends! I'm here, home too... I would like to ask a question about the connections of dc motor. May I ?

   Here in instructables, I saw a " pringles wind turbine" . I'm also looking for making sth. like that. Over there, all is ok. But, our friend doesn't tell us how we connect that wires. All is fine. We stick magnetson a cd;  and these wire rounds, to an other cd. But, after this point, we don't know how we connect wires together. After, diode connection, and battery connection.     Can you please tell me how I have to connect all of these tinks together and have electric? Thanks for your helps from the beginning.            Devrimm pc: My English isn't perfect. So, I prefer some pictures while answering my question...

Can someone Explain to Me how Wifi Antenna Extenders work? Answered

Could someone help explain to me How wifi antenna extenders work? To me It seems like you would be able to send packets to the network, but it wouldn't be able to send them back, making the TCP/IP Handshake Incomplete.I am Talking about having a USB wifi Adapter with a Pringles can antenna or something like this: (https://www.instructables.com/id/Uni-Directional-WIFI-Range-Extender/), and using it to connect to a Starbucks or something.I get that the metal reflects the signal, so that it is strengthened, and can be pointed towards something, What I Don't get is how once you send the signal, how does the signal get back to you when your out of the routers range?The pic is a rendition of what I think should happen, while using a wifi-extender antenna trying to connect to another place's internet that would usually be out-of-range.

Diy LED strip light powered from a solar powered battery bank (for painting/drawing at night)

I like to paint nightscapes and so far headlamps are not working so well for me. I used a portable light bar one night that worked well (on loan) but it was too heavy. I've been through stores looking for the right thing...and harbor freight came close. But I need something lighter weight and less expensive.  Two or three led lights don't cast enough light and 30 led storebought lights are too much light. I have a solar powered phone charger with battery bank (with usb connections) that I now plan to use as the portable power source. I plan to use a pringles potato chip tube as the light housing that can be attached by clips to my pochade (really a mod'd cigar box) on top of a camera tripod. I guess my main concern is weight on the box, so I thought running a cable off a power source hanging from the tripod would be more secure and less likely to fall in my palette (as has already happened). I need help figuring out the circuit board; and also choosing the right white led for color purposes. Any thoughts?

Blakes 7 Teleport Bracelet

This is how to make the magic blakes seven teleport bracelet!Ingredients:one cardboard roll, such as a poster or postal cylinder or the cardboard roll from inside a roll of packing tape; diameter 8.5cm, width 4cm (cut to this width if need be, using a saw or knife)cardboard, thick enough to be sturdy, thin enough to be flexiblethin cork (optional)plain paperglueblack or dark brown foam rubber (optional)silver tape width 1.5cm OR aluminuim foil cut or folded to width 1.5cmAntique Gold or metallic brown paintgrey paint OR a round grey button 2cm diameter OR grey tapered paint OR pink paint OR red paint + pearl nailpolishbrown packing tape or beige paintclear or red contact (optional)Visual Reference:Refer to the Liberator Teleport Bracelet diagram in the Horizon Technical Manual.Instructions:Cut your roll to the right width if need be. If the roll is too thin and flimsy, stick a layer of cardboard over it. Cover the rough edges with paper.Cut five strips of cardboard, one 15x3cm, one 9x3cm, one 1.3x3cm, and two 2.5x1cm (measurements will vary depending on the precise size of the cardboard roll). If the cardboard is thin, cut twice as many strips. If you are using thin cork, cut one strip each from the cork also.Stick the strips onto the roll, making sure they evenly positioned in the center. Check the diagram for where to stick them: the two long strips should be next to each other with a small gap representing where the hinge of the bracelet would go if it had a hinge. The small 1.3x3cm strip goes in the larger gap between the long strips - this is where the red button will go. If using cork, stick the cork down first, and the cardboard on top.When all the glue is dry, paint the bracelet with antique gold or metallic brown enamel paint. Do more than one coat if you think that will look better. Wait for the paint to dry.The red receive-button is made from the two smallest strips of cardboard stuck together, covered with white paper, painted red, and covered with contact to make it shiny. Another way of doing this is painting it red, and then painting it with white-pearl nailpoilish to get that glowing pink-red effect. Glue this as indicated in the diagram.The grey transmit-part is made either from cutting a circle of paper or thin card (1.5-2cm diameter) and painting it grey, or by using a grey round button and cutting off the shaft so that it will stick on flat. Stick this on as indicated in the diagram.Cut out silver tape or foil and stick on the bracelet as indicated in the diagram. Cut out (very cleverly) pieces of brown packing tape in the shapes of the alien characters that decorate the rest of the bracelet and stick them on, or else paint them on with beige paint. You may wish to paint the whole bracelet with clear enamel to protect it.Optionally add a lining with foam rubber, to aid the bracelet in not falling off when you wear it.NOTES: Cardboard rolls: the roll from inside a large roll of packing tape comes closest to the right size. A large postal cylinder is too large and a small one is too small. A Pringles packet is too small, but may be easier to obtain. A Pringles packet is easier to cut but is also flimsier; it is recommended to add bulk by sticking on more cardboard to thicken it up.Cardboard: most cardboard you can buy will probably be too thin. The backs of note-pads may provide thicker stuff. The disadvantage of thicker cardboard is that it will not bend as easily, and the cardboard used here must bend. An alternative if available could be thin cork (a few millimetres thick); this will bend fairly easily and add the bulk you need. But only bother if you happen to have some (maybe left over from someone's redecorating or the like). I used it for mine, it worked beautifully.The red button: building this up from strips of cardboard is fairly tedious, and if you can think of a better way, do that.I know Michael Keating!He Played Vila.

Looking through the Instructables submitted to the contest and comments on the finalists' forum posts, it's clear that this is happening all over, and it makes me smile every time. Congratulations to all the winners! And, thanks to everyone that entered. Even if your Instructable didn't win a prize, I'm sure it has had a positive impact on someone's life and will continue to do so.

TV antennas and what is possible indoors

Back in my young years a TV antenna was on the roof, quite big and only required to get 3 or 4 channels at best.The basic design of these Yagi antennas has not really changed since then.Same for the antennas required to get UHF and VHF channels at the same time.They either comes as two seperate antennas with a mixer or as a UHF antenna with some added loops for UHF.To talk some basics:For UHF you can get away with quite small dimensions for your antenna bits.After all a quarter wavelengths here is only around 15cm long.With VHF though we get already 30 to 40cm here depending on the channels.So called bradband antennas claim to be able to get a wide range of frequencies.That however is only true for their dedicated frequency band.If you take a normal whip style antenna then this becomes obvious - just compare the lenghts required and you realise "going the middle way" will mean neither UHF nor VHF would get any usable reception.For a long time now there is the option of so called "fractal antennas" to get better TV reception....Fractal antenna? What the heck is that?The theories behind them are about as old as fractal antenna designs that were not even considered to be fractals.Let me explain with the example of a standard FM radio antenna.For them we use frequencies from about 88 to 108MHz.And of course, for our cars they are always on the roof or mounted somewhere around the wheel arches.Some cars however does not seem to have any antenna depsite having a working radio.In this special case rest ensured they do have one, usually behind the plastic bumper bar ;)I like to go off road every now and then and lost count how many times I had to replace my antenna after getting to close to some bushes and trees.As a solution I used some thin wire to create a L-style anteanna on the inside of my windscreen.And funny enough it picks up more stations than a "proper" antenna outside.Really old design and if you think about it then an antenna with a kink that looks like L is ""self similar" - the definition of a fractal ;)More complex shapes like the Sierpinski models do exactly the same just in one more dimension.Cell phones use them as well as you WiFi router that has no external antenna anymore.Their designs and looks are so different that it is next to impossible to list the currently used shapes here.What it comes down to, when you just take a very basic flat or wire shape is that the straight single segment of the active antenna is split into one or many shorter segments that change the angle.They all have similar relations to the wavelenght still.Means really long segments might be half of a wavelength while the shortest bits are just 1/64 of a wavelength.Think of it (far too simple of course) like amny matched antennas combined into a single one.With that often comes a destinct radiation pattern, usually with a quite narrow beam angle that provides a quite high gain.Are fractal antennas any better than for example a proper Yagi antenna?You can ask 100 people and you get 100 different opinions for this one.This is mostly due to some simple facts like:Not caring about actual comparisons.Not being accurate enough when building the fractal antenna.Using just very basic equippment to compare results.For example when you have a 30 year old and quite small TV antenna on your roof and struggle with digital TV reception than you might want to just replace it all.In some case even the old rabbit ears on your TV set will work better.But take modern Yagi antenna with 12 or more segments and even station that are 100 miles away have a good chance.Comes down to possible gain, frequency match and of course how well the antenna is aimed at the transmitter.Then why is it that some fractal antennas still seem to perform so much better?The big antenna scam....If you paid attention during the intial DVB-T rollout in your country then noticed two things.a) You were told you need a TV or set top box capable of receiving DVB-T signals.b) You need a suitable antenna.Well, A is obvious but for B a lot of people got scammed badly.You see, in almost all cases the frequencies allocated for TV signal did not change at all.And an antenna really does not care if the incoming signal is analog or digital - it only cares about the frequency.But more and more local stations often meant that the trnsmit power is limited.After all it makes no sense to have a 500kW transmitter if the area to cover is only about 20 square km big.So people were told they need new antennas once the noticed digital TV is more like playing Tetris, blocks everywhere....You analog TV had no problem with a slightly weak signal, you did not really notice it unless the weather was really bad as well.All the benefits of digital TV however only work with a proper signal strength.If your areas still has both analog and digital TV channels then have a look on how your local transmitter provides the signals ;)Part of the big scam was hiding a very simple fact:All analog TV is transmitted in a horizontal orientation while almost all digital TV is transmitted in a VERTICAL orientation.Ok, we already gain and ignored it but why would the orientation be important?Your radio antenna is vertical because the FM signal is transmitted the same way - the "waves" if you like go up and down like a sine wave.You still get reception if you turn the antenna 90° to make it a horizontal one but you will realise that weak station are no longer available.The same happened with digital TV.And if there is only digital TV left in your area then simple turning your antenna 90 on the mast to have the single elements vertical instead of horizontal gives you top reception again ;)If you struggle to get all station then just try it out before buying a new antenna ;)Modern fractal TV antennas come paper thin and often with rediculous claims in terms of gain and range.On Fleabuy you can even find models claiming to get stations from over 2000 miles away LOLSome even come with the fake claim of being omnidirectional, meaning it does not matter where you place them or how you orient them.A fractal antenna can't change basic phsyics though...High gain mean highly directional or at least with a very flat radiation pattern instead of being more like a sphere.A high bandwidth means you compromise on the gain and/or the phsical dimensions.For example a thin whip antenna is quite limited in the optimum bandwidth while a piece of tubing provides amuch higher bandwidth but at the expense of gain (and some other problems).A fractal antenna can compromise between the two worlds much better than anything straight.And you would even need to make the traces on the plastic extremely wide because you can simply add different lengths for different frequencies.Means a wideband fractal antenna for FM, VHF and UHF basically is three different antennas combined into a single one.It also means that there is usually always more than just one single element of the antenna that is receiving a signal.If you experimented with WiFi antennas for your router or modem than you certainly found the famous Pringles can antenna - highly directional and with an insane amount of gain.Works exactly like a simple directional microphone.And you could, at least in theory do the same with a TV antenna - if there wouldn't be the problem of the wavelenght.A pringles can works for WiFi because the wavelenght only requires an antenna of about 3cm in lenght.You might not want a row of steel drums with a diameter of around 80cm on your roof just to watch the news though...Ok, if I need a new antenna anyway then should I get a fractal antenna or not?I try to make it simple:Roof option not possible or too costly AND your transmitter is not too far away then try one of the cheap paper thin antennas you find online.If you already have an antenna on the roof that is suitable for the frequencies you need then check it to know if it is still any good.With age and weather comes corrosion and some antennas are connected badly in this regard.Sometimes you are lucky and all it takes is to cut off a few cm of cable to get back to clean copper and to give the terminals on the antenna a good fine sanding or a wire brush treatment.In other cases you might find an amplifier under the roof that has faulty power supply ;)And well, certain animals love to chew through your cable...If all is goo from antenna to TV then as said try to flip the antenna 90° to get it vertical.No, I did not mean to point it up to the sky..... ;)I mean rotate it around the x-axis if X is pointing in the direction of the transmitter...
