What size

I am wondering which tv is best to play video games and watch tv on a day to day basis either this one, this one, or this one.

Hi mates, do any mof you knows how to make a mould bigger than the original model? In other words, anybody knows how to copy a small figure in a bigger size? thanks in advance for your answers from Spain.

I'm trying to do an Instructable with Excel, but whenever I upload screenshots into Flickr or just directly to the instructable, the full preview makes them all fuzzy and small. How do I enlarge the picture so people can actually see them? I've tried Photoshop to enlarge them, but it didn't help, and I am not a Pro Member, is that why? Thanks!

I was wondering what the actual length of a long bow with a string length of 48inch amo would be I basically want to know what the length of the bow itself with the string on would be??  Also wondering if a 30 pound draw or 20 pound draw would be better for a small person small game hunting?? Thanks!! 

Something appears to have broken in the past couple of hours (it may already be fixed) involving the image thumbnail generator.  On the Recent Step-by-Step page, you can see two I'bles with essentially blank images (see below). Clicking into the I'bles themselves, it looks like the thumbnail generator just took a little piece off the upper left corner, instead of either scaling the original image (which is what it ought to do, in my opinion), or cropping out a central region. Once this bug is fixed, I think it would be considerate to the user community if the thumbnail generator could be re-run on any images uploaded in the interim.

Can someone tell me the optimum image size for a featured image?  I want to add some text to my image but would like to get the size correct the first time.  Perhaps 300 x 300? Thanks-

I'm building  "robot horse" for my daughter, and have the metal frame mostly complete.  The plan for locomotion is to mount reversible powered 6" wheels to the outside of each hoof, and steer tank-style. My biggest challenge is finding reasonably priced, reasonably powerful drive motors for each wheel.  My issues are  1)  I'm inexperienced at specing dc motors.       A) I'm not real sure how to translate published specs into real world motion.  I don't know exactly how much power it takes to get this reliably moving over rough ground to a top speed of around 1 mph.  I also don't have a good sense of much voltage you can pump into a DC motors.  (IOW, should I be able to push 2 x the rated voltage for a quarter second to get it moving? Will the motors naturally increase their amperage at a constant voltage (and thus power) as they are resisted by torque?)  How much power will starting from a stop take?  What about a slight uphill slope?     B)  I'm not sure what form-factor is best:  Gear motor?  Gear motor with final drive belt?  I would like to use worm-gear motors, as I think it would be safest if the wheels didn't move when unpowered. 2)  Hunting around supplier web-sites, I see lots of $20ish gear motors that use 5-20W of power.  Great price, but would 4 of them make enough power?  (See #1A above)  Also, I see lots of fractional HP motors for >$100 that would unquestionably be strong enough, but would cost more than the project justifies.  I found very little in between.  Are there motors and gear boxes that could power this at a reasonable price?   Relevant clarifications and details: 1)  The horse is about 40" high at it's withers (shoulder) 2)  Frame is made of 1/2" square tube steel. 3)  Normal rider + vehicle will be about 150 lbs.  However, unquestionably, larger kids (or multiple small kids) will at some point hop on it and try to ride it.  At 250 lbs. rider+vehicle weight it doesn't have to go fast, but shouldn't burn up the motors. 4)  It'll be powered by a lipo battery pack that shouldn't have any issues with 20A+ max currents and can be sized as needed for voltage. 5)  I'd like to keep the motors and gears <$200 total, if possible. 6)  "Rough ground" = flat grassy turf or reasonably smooth gravel. 7)  Motors need to be reversible. Can anyone lend some perspective on what type of motors to buy for this?  How much power/torque should I look for?  Any advantages/disadvantages of any particular gearing style for this application? I am assuming that motors on each wheel are the way to go, but if there are any other power transmission schemes that would work better, I'm all ears.

What are the maximum size and resolution for images ?Are images automatically resized on upload ?Thanks!

For a future instructable, I need to know; What is the size of Hotwheels track. ie the inside wideh and the height of the side walls? Any help appreciated.

I need to know what size compressor flywheel pulley to use for a 3450 rpm motor compressor 1500 rpm dia. 13 3/4"

When a hex nut is referred to as "X"mm, is that measured to the ridges of the thread (the green line on the image, or into the troughs of the thread (the extra red parts of the line)?

While I was watching TV, I heard that China has made a life sized gundam. I have watched this show a few times, and I think they made 'White One' or Amour's gundam, I think that his name is right. They might have made a Zaku too, or maybe just its head. If you have pictures or any opinion, post away.

Why is there a limit to how big the wheels can be and to how long the lever arm is?

OK... is it just my computer, or is the font on step 4 of this Ible smaller that normal? This seems to only occur after the bullets. Bacon Guacamole on~the~half~shell Windows 7, Google chrome.

I have a relay with an Outline Dimensions:(15.5x10.5x11.8)mm 5V,3A--> Switching voltage 230VACDatasheet is given above..could you suggest the similar capacity with small in size (not a solid state relay) relay ??i was search website like MOUSER,LCSC .didn't find any suitable one.

Hi guys i need help i bought a controller for guitar hero and im building a full sized body for it out of wood. I need some tips and tricks if you've got any and im open to all ideas. I haven't started yet so you can give me body ideas too if you want i was thinking like a Frontman body or a Gibson les paul or the warlock guitar (Google search the warlock guitar in images it looks really cool) but that would be hard. -themuppetmafia

I'm having trouble with the sizing of the .stl file model. In blender it says that I have everything correct and I've made sure that the scaling was applied but every time I upload it it says that its wicked tiny. I was hoping someone could give me suggestions on how to fix this problem or at least think of something that I haven't thought of yet.. 

I read that regardless of the size of a speaker connected to an MP3 or something, the sound output should remain the same. I assume this was incorrect because using large computer speakers seems to disprove this. Is this because the speakers have more surface area and generate more sound? So will using large speakers at max volume drain more energy than small earbuds at max on the same music player?

  Just got a new bike and size seemed fine until I got it home and tried it out for real.  I cannot stop and get off the bike without huring myself on the crossbar.  I am a 51 year old woman who hasn't been on a bike for several years.  I don't remember women's bikes having such high cross bars when I had a bike before.  Now all ladies bikes seem to have high cross bars.  Has anyone any suggestions on what I should do to resolve my problem?

Hey all! I have this problem, where all the thongs I get with outfits are too big for me. But, seeing as I love matching outfits, I really hate to throw them away. Yet I just can't figure out how to make them smaller. It's killing me.  Any help would be much appreciated. Thanks!

Ok Im making a speaker, I´ve got 3 speakers connected in parallel and I want to buy an amplifier from Maplin. What kind of amplifier should I buy? Speakers:3W+3W+5W=11WMy multimeter says theyre 2 Ohms but thats because theyre connected in parallel really they are4Ohm+4Ohm+8OhmSo basically could someone tell me which amplifier to buy (it doesnt matter if its a DIY kit)

I bought a spare tube with my new bike, and just noticed that it's not quite the right size, but I don't know a lot about bike tires. My tire says 700 x 35x My spare tube says 700 x 28x-32c Thanks

I'm working on a diorama that has my local model shop in it, so i figured that, even though the windows are tinted, i can at least put some models and stuff laying around... so i could make paper model boxes. i have the dimensions, but i have two problems. 1) i don't know how to transfer my calculations (1cm x0.7cm x0.4cm) to the computer, and 2) i dont know how to make the model boxes 1/24 smaller without losing virtually al the detail... obviously im not looking for something perfect, but i also dont want the box top to be some random coloured pixels. can someone help with this? i could draw them, but i was hoping to offer these to other people, by making an instructable.

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.

HI...i was found a tutorial here about make a Halo costume...but i saw that the size of the same pintted is big how by a adult person...but i need the model in the size to a boy of 12 YO...how i can resize the model to a specific size?...Exist a table of reference about size in pepakura VS size in reality? Thanks

I'm doing a science fair project on Parachutes and I need to know if the size of a parachute matters  

What is the reccomended size of a image for upload to Instructables?

How can I make the text in the pdf download larger? It is hard to read in the tiny size it is now.thanks,amy

So who else has got a full size hovercraft in the works?

When uploading photos for a new Instructable, should we first reduce the file size? Or does the site automatically do this? Have not seen this mentioned. Thanks.

I'm doing a science fair project on parachutes and need advice 

I want to make a couple of life size palm tree cutouts for my fence. I'm not very good at drawing, how can I do this without a projector?

Hi friends....I love this site and do like to win, even if it's just a bunch of positive comments!  Recently I won a t-shirt and I didn't realize how small/close the sizes run.   (I believe I requested a women's large and in the comments I noted that I wanted the equivalent that would fit a women's chest 36-38".  I was disappointed that the Tshirt ran exactly 37" with no room to breath.  Unfortunately I didn't realize I was supposed to add a few inches for movement as none was built into the size.) My shirt has not been worn and it still has the manufacturer's paper tag attached.  Is it possible to return it to Instructables for a larger size? If so, then I'd like to request something that measures 42" from armpit to armpit - which would be great after shrinking!  (I realize the larger size may be considered too large for the female sizes available, and if so, the equivalent man's size would be appreciated over one that doesn't fit) If this isn't an option, perhaps future winners can be asked what size they want their shirt to run "from armpit to armpit".  Not only will this make more T-shirt winners be happy, but also, more Instructables advertising will be seen on the streets ;-D mega thanks!

Can i enter the contest if i live in ireland?... i need to win that camera

I've been having trouble with image comments not showing up the right size in my instructable, How to Build a Spark Gap Tesla Coil (link). In step 2, this is especially visible as some of the image comment boxes appear to be larger than the images they are posted on! The comments are supposed to be the size of the image, not smaller or larger. I've tried resizing them to the correct dimensions, but it doesn't work. Is it just my browser, or is something else going on? What can I do to fix this? Thanks! Xellers

Hi, just wondering what is the correct picture size for Instructables ? I'm uploading 700 x 519 pix pictures.  Also, since all my pictures on Instructables look wrinkled, I was wondering if it's possible to choose to show pictures in static means ( simply list all pictures in line, so visitors can scroll down instead of click for the next picture ). Static pictures may provide much better image quality. -- My poor suggestion.

I have built several adult soapbox derby/ Gravity cars. I'm working on a new build that may require a smaller front tire, such as a 16inch tire. My plan is to run 2 26inch rear wheels and 1 16 inch front  wheel, with a total car weight of 225lbs.   Since there is no gearing, just gravity, and just considering size, will smaller front wheel effect my speed? Thank you

Pete Hennessey of Melbourne, Australia has made a series of full-size plywood replicas of space-related items. Amazingly enough he modeled them in Illustrator and the whole process of making a model of Hubble took him three months to make. Yow! peter hennessey: my hubble via MAKE

So I bought one of these to play with: http://www.ebay.com/itm/130935883579 The transmitter board always gets really hot and smells faintly of something burning.  Is this normal?  Should I use some type of heat sink? Anyway, I discovered that you can add another coil of the same-ish size to the transmitter, and both coils will work.  However, if I remove the coil and add a single coil twice the size, it does not work.  I'm curious as to why.  What determines how large the coil can be? 

Anyone know where i can get a case (empty or made for it) that is 24"X4"X4"? cause im trying to restore an old metal clarinet and the case that came with it is shot. anyone know where i can get that size case (if so, with a bag built into it or some kind of compartment inside the case)?

I was wondering if any one knows if there is a double sided rack and pinion steering for a full size car. this would allow the car to have 2 steering wheels, one on right and one on the left. Does someone make kits for this? I reminber seeing mail cars and driver ed cars haveing this, do any one know how it is doen? thank you.    

I plan on making an Instructable about making a keychain sized simple circuit. I will be using the circuit board  shown below but I'm having inventors block. It should be able to take the stress of being jumbled up in a pocket. What should I put on it? If I use your idea I will mention and thank you in the Instructable. Thanks in advance.

you know one of those key chain kind of things that play sounds when you press a button? is it possible to make one of those or hack one to make my sounds?

Hey, I would like to know how to fix this font size problem I'm having. I don't know if HTML just doesn't allow it so that may be the case. So I have a div with an id of "NavBar" and a div with an id of "AccountList". The "AccountList" div is inside of the "NarBar" div. In the CSS, the "NavBar"'s div has a font size of 36px and a color of #e1e1e1. I want my "AccountList" div to have a font size of 19px and a different color. The problem I am having is that the "NavBar"'s CSS properties override the "AccountList" properties. How can I get around this? I will not take the "AccountList" div out of the "NavBar". If you want to see the actual thing I have and what I'm explaining, here is the code (Just save it as an HTML to run it): http://pastebin.com/ztX5Us7A Thanks,

Hi! I want to built a bench like the following: http://passim.co.il/picllery_files/garden_bench_1.jpg  someone can send me sizes or diagram of something similar or even link to toturial that made something like this?  thanks!

I want to rotate a stainless steel shaft that is in a vertical position having a 40 mm diameter and 300 mm length. The motor will be attached to the bottom of the shaft, so when the motor is turned, the said shaft will rotate. The shaft is not driving anything, it just turns on its own. The shaft's mass is 3kg(according to my calculations).  I want the shaft to rotate at an angular speed of 45 degrees per second. Having this information, how can i size the motor that will do the job. What kind of torque would i need, what kind of wattage. Please show me some calculations so I can know how motor sizing is correctly done.  Very much appreciated, Chris

I've got a clarinet mouthpiece and some pvc pipe...25mm but i'm sure I can adapt it bigger if necessary. Is there some elegant equation (like where the natural harmonics on a guitar lie) to calculate the spacing and diameter of the finger holes for chromatic tuning?
