Sorting confusion...

I'm confused about the sorting function instructables employs.Today, (jun5, 08) 11 of the featured instructables are over one year old. Two or three are from 2006.With Zeitgeist, Random, and Popular being less "temporally ordered," I'd have though Featured would display the most recent featured projects...

Confused Crocodile

I'm a confused crocodile...I wanted to compete in the 3d money clip challenge and will still design something for it :) . After numerous times of trying to make the software work it just didn't so I'm going to try to use some other CADs that I have. With that being said here lies my confusion about this contest.The prize(s) for the 3d money clip contest is a $100.00 credit for five winners. I went to the website and there's a membership fee and if you aren't a member then the cost of services is higher. Plus, there's an hourly charge for the services and I'm basically confused as to the benefit of a $100.00 voucher/credit. Would that be enough to make a 3d print of the 3d model for the winners of the contest?

Copyright Confusion

Hi all!  New here, first post.  Hopefully I'm putting this in the right spot and it hasn't been asked.  Was wondering, so you make those little magnets with a picture glued to the back but is there a copyright discrepancy with using images that aren't your own and making it into something that is your work?  Crafts like that are tedious but not hard though it seems like if those selling things like that in shops wouldn't be making those magnets and such if they could do such great art.  Thanks for any info

MOT confused?

Been watching a lot of videos on youtube about increasing the voltage on Microwave oven transformers!. what i cant undrstand is when people take out the secondry windings of the transformer & replace it with a few turns of 10 gauge wire to increase the power how does it work? as from  what i've seen the 10 gauge wire still has the insulstion on it so how does the current cant get through to produce extra power?. Also what do the shunts do in the workings of the transformer?. can anyone explain this to me in laymans terms!. Thank's, Tezza1.

Legal and copyrights confusion.

Hey everyone, I love instructables and I've been working on my own tutorial for the last few weeks. I am not far from publishing the instructables. Recently it came to my attention that I might have some legal/copyright issues. I built my DIY using some parts I took down from other products that are still on sale. One of these parts is copyrighted but not patented. I was wondering, due to the DIY and instructables nature if that would be an issue for me? I am not reselling the DIY or pushing people to do the same as me and even give indication to future makers about how to obtain that part legally. I cite all the sources of the original product from which I borrowed the parts. Would it be ok if I publish my instructables like this or should I avoid talking at all about the "borrowed" parts? Also, if a newspaper or magazine wanted to publish an article about my instructables, would granting them sole publishing rights interfere with using the "borrowed parts" that I talk about above? Would I even be able at all to grant them these rights, given the general terms of the CC license (Non-commercial share-alike)? Does this CC license allow anyone to publish an article about my instructables without my written consent (print and online), so long as they cite the sources? Thanks in advance for helping me out, I'm a bit confused!

Confused College student

Hey guys, I haven't been posting alot lately, but I remember whenever I would post you guys would have the nicest and thoughtful replies out of any forum I've posted on.... So I was kinda wanting to hear everyone's thoughts on college, careers, etc... I'm 20, currently in community college, have been since I was 18, should have my associates....but no, I don't. Honestly, I haven't taken school seriously at first, haven't applied myself, just done whatever I wanted, and I'm just now getting serious, and the last two semesters, GREATLY improved my GPA and definitely taking school more serious. At the moment I just keep taking general courses since I don't know what to do. I've wanted to do things from fashion design, to web design, personal training, massage therapy, but mainly what I want to do is have my own business eventually. The best case scenario, would be for me to have my own t-shirt line that later turns into a full fledge fashion design. Problem is, telling the parents I want to make t-shirts for a living doesn't always go over well....as well as most business entrepreneurship programs I've researched require calculus...andddd, I'm having trouble passing college algebra..you know? And then part of me is in love with the idea of being a musician...I love to write lyrics, and I've fooled around with recording at home and etc....I'd love to travel, even if I didn't make millions, that's fine....just even able to make enough to survive...I'd be fine if I could pursue that... And thennn, there's all of you! I read books and magazines about DIY and sites like this, and they always have stories about a bunch of young people turning in a empty building into a super awesome music venue, or some other artistic place... Or people that have started new unique businesses and ideas. I mean what the heck! I don't know what to do...I'm about to turn 21 this summer, and have no idea what I want of life, all I know is that I want to have fun doing whatever job I choose, and be able to live comfortably...even if it takes me awhile... And I have no idea how to do that :(

Contests; they are getting a bit confusing

I am a bit confused...I got the distinct impression that a photo contest was a photo contest, not a 'best instructable' contest; hence the camera as a prize. Almost every contest has been based on the subject matter (and that makes sense); submit a new i'ble on how to make a better cake and win a kitchen device; submit a new i'ble on a good way to use LEDs and win a product that helps make things with LEDs easier. Therefore (for some odd reason) I thought the object of this last I MADE IT photo contest was to enter a really good (possibly award winning) photo of something you built (rather than enter an average photo of something really good). Don't get me wrong, all of the instructables entered are good, but submitted as award-winning photos...not hardly. Was this just another popularity contest? How did I miss the mark here?

brushed induction motor confusion? [answered] Answered

My father and I are currently restoring a metal-working lathe, however, we do not have 3 phase power to power the original 0.5HP 3 phase motor. We do, however, have a slightly smaller 0.25HP motor. At first appearance, it seemed to be a simple AC/DC brushed motor with a field and winding on the armature. There was no wiring diagram supplied with it, but in one configuration (what appeared to be the ameuture and field coils) are wired in parallel for 120V operation. This did not seem right, since the field coils will be simply shorted across the mains, but I assumed that since we are dealing with AC and inductors, this is OK. It works flawlessly, but reversing the polarity of either the fields or armature would cause the motor to sit and buzz. If started manually, it took off slowly but sounded awful. I need the motor to rotate in both directions and do not have enough materials to do this mechanically. On closer inspection after dismantling the motor, it appears there are 4 brushes, connected together in 2 pairs. They are not directly connected to anything. The 4 wires coming out seem to be just for wiring both field coils in either series of parallel for 110V and 220V operation respectfully. Perhaps even more strange, the 4 brushes are mounted on a centripetal switch, which disengage the brushes from the armature. I was able to make out on the rust that it said "revolution induction motor." So I reasoned out that after the fields are energized, it will induce an electrical current in a few of the coils on the armature, and the energy would flow to the other 2 sets of brushes, causing a different set of coils on the amature to energize and this would initially start the motor. After it gets going, the switch disconnects all the brushes and the motor operates as a simple induction motor. My father used to rebuild motors for a small company, and this is in fact one of the motors he repaired. Although he is skilled at this practice, he does not understand the operation of induction motors and can only figure out wiring by strictly following a diagram or trial and error. I am curious about what this type of motor even is, and how it works! In th meantime, I will research induction motors and how they work, and see what I can learn.

Question about a flyback's polarity Answered

Hello, I am confused with this flyback transformer I have. I have a pulsed DC input on the primary coil (pulses from 0 to 15V) and that creates high voltage in the secondary coil. When I connect that input in the opposite direction (wrong polarity) I don't get high voltage any more. The possible explanation for this is that the primary coil has a diode in series with it. Now, I'm confused by this because I tested if there actually Was a diode in there (by connecting a DC supply and a DC motor, in series with the coil) and the motor always works! (also tested with a halogen light) I put the coil in series with the motor to test if there is a diode inside. If there would be one inside, the motor should not work in one of the two cases, when I switch the pins of the primary coil. So, as the results of the test tell me: there is no diode in series with the primary coil. could it be possible that there is a diode in parallel with the primary coil? If that's not possible, how come the flyback is not working when I connect the polarity incorrectly? Could someone please help me out with this? Thanks, Electorials

Using a left/right audio testing program on my phone I tried wiring the wires up to a set of headphones to test which wire is which. When I wire up the green right wire to the right channel and the copper colored wire to the ground I get sound through just the right channel as I would expect. When I add the green wire from the left channel to te left connection on the headphones both channels play through both sides of my headphones. When I did those tests I was assuming the copper colored wire was a ground. I then reversed the colors assuming the green wire was the ground and repeated the same test with the same results. No matter what combination I connect the wires in I cannot isolate the left channel to the left side and the right channel to the right side. Anyone have any ideas?

CONTESTS

Would it be possible to have a board where contest applicants can post their entries. It gets VERY confusing when they are mixed with the general instructables. This doesn't seem too hard to do.
