Image Size

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!

Something is wrong with thumbnail generator today

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.

Choosing drive motors for kids riding toy

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.

Amps and Speaker Sizes

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?

Bike size problem.

  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?

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.

Exchange Tshirt for a larger size?

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!

wireless charging coil size

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?

Font Size Html Trouble?

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.

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.

How to size a DC motor? Answered

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
