Guides are different!

I've just released a new version of the site. The main difference is in how Guides are handled. We've changed them so the Instructables referenced in them are linked directly, where previously the Guide simply contained links in the text. Aside from allowing any updates made, or changes of picture, to be immediately picked up, this change also lets Guides be created more easily.  It's also a prerequisite for another feature we're preparing… which I can't tell you about quite yet!

Arduino help

Hi guys! So, i saw the LED cube experiment and decided that i would try one myself. Although i can definitely say i am a newbie when it comes to microcontrollers, i still would like to try and understand them. I am planning on making a 4*4*4 or 5*5*5 cube, and dump the programs that the various users have submitted.  Now, most of the instructables have not specified which arduino board they used, few have, and those who did, each his own. My questions are: What are the differences between them? I mean, i saw a Due, Fio, Leonardo, Uno, Duemilanove etc etc.  Are they interchangeable?  Secondly, which one is better to use for the cube project? Or all the one and the same? Personally, in my area, Duemilanove is pretty cheap. Third, i would really love to understand the basics of arduino, and also learn to program it. So, if anyone have any good site or tutorial or other resources for a COMPLETE newbie like me, please do point out!  Thanks! :)

What Is the Difference Between a Challenge and a Contest?

Does anybody know the difference between a contest and a challenge? It has been driving me crazy! I saw a forum that said they wanted to create a challenge. Is it possible to create a challenge?

Topic by DIYEnPointe   |  last reply


Contests vs. Challenges - what the what??

Hey gang! It has come to my attention that there is confusion about the difference between contests and challenges.  And believe me, we understand - we're still hammering out the details ourselves!  So I'm going to be super candid, and give you a glimpse "behind the curtain." The main difference as we see it is: Contests are pre-determined and often sponsored by awesome folks like Radio Shack or Singer.  They take more planning, and are usually open for longer periods of time.  Typically the amount of prizes given away is much greater than in challenges. Challenges are determined by the editors who run them, often on a whim, or you know, for fun.  Challenges are completely built and managed by said editors, so sometimes the html looks funky or things don't always go as smoothly as the well-constructed architecture we have in place for contests.  (I'm still learning html!)  They're meant to be smaller in scope, faster, and have a different prize structure (the more entries, the better the swag) than contests. Challenges started as an experiment.  They are labor intensive to run and maintain (I'm still working on building a system for tracking old challenges and winners).  Everything happens by hand.  Sometimes the rules change, and sometimes the pages look different.  We're still experimenting with the best way to do these so we can set standards for them. And once we know that this "experiment" has been successful, we can try and lean on the development team for some support to make it all look (and run) much better! The distinction between the phrases "Contest" and "Challenge" is new.  You may notice that some of our Contest banners still say Challenge on them.  We were originally calling contests "Challenges," and the editorial experiments "Speed Challenges."  But then there seemed to be some confusion about whether or not the projects submitted to "Speed Challenges" had to be speedy themselves, and then some of the challenges needed to run for a month or more due to their theme (hard to build a robot in a week!), so we scrapped the "Speed" part.  Eventually we settled on differentiating the two simply as "Contest" and "Challenge."  There's even more debate about identifying the challenges with the editors running them, vs calling them "Weekly" challenges (which we know can be a misnomer), and lots more.  You probably didn't need to know all that. Anyway. Please do feel free to use this space to vent your frustrations, offer your suggestions, and ask for clarification.  Just today I mistakenly swapped the terms challenge and contest in our daily meeting, so I feel your pain.  And really, we just want to make you guys happy.

Total Views Count - 12/08/2010

Firstly, sorry about the lack of updates to this group of late. I accepted a job working for steveastrouk and lizzyastro and started 2 months ago. After moving house I was slow to get my internet set up again. Anyway, it's working now, so now I'm back I should be around a lot more. You can have a look at a few of the things I've been up to since moving on my blog. Group-wise, since the last update I posted to this group HQ have rolled out the baseball card update so you can see your total views instantly on your profile. While that makes this group less useful I hope people will still want to pop by each update to see how much their total has increased since the last run. This update also means that my Perl script to fetch the stats now takes 30 seconds instead of 3 hours as it has to load less than 100 pages instead of 1000s, so I can run it more often! I will be running it weekly now, every Thursday after work. Expect the patches to keep coming! So here are the results for this run. Interestingly Scoochmaroo and DJRadio have negative gains, I'm guessing from changes to the way guides work.

Same Same...but Different

Two years ago I spent my fall semester in Vietnam.  While shopping in the markets I often heard the phrase "Same Same...but Different".  This usually referred the knock-off North Face bags (mine fell apart after a month) and designer sunglasses that were, according to the vendors, just as good as the real thing, but a little different.  Although knock-off often has a bad connotation associated with it, it really just means same same but different. What types of things have you encountered in your everyday life that you've thought, "hey this is just like this other thing I tried"? examples... - the perfume I wear smells just like this designer perfume that is 3x more expensive - this bands has a similar sound to this band; they're a little less known but their music is just as awesome! - the city I live is a smaller/larger version than this other city I visited you got the idea

Can We Compare IT Sector with Public Sector Undertaking (PSU), Indian Engineering Services (IES)?

Now a days electronics engineering students have a big problem to select a job in private sector just like a IT SECTOR or in a government sector for example IES or PSU. In my point of view all the above job have good future and good respect and there are some limitation for every sector. If someone ask me this question and i don't have a any choice then my answer is ....... I think we can not compare government sector with IT sector at this stage. Because in govt sector for example IES . Indian Engineering services will give you a huge respect in every sector, promotion, good environment, peaceful life, safety of family etc. When we talk about Public Sector Undertaking (PSU) this will also give you more work experience than IES and promotion, good environment, peaceful life, safety of family etc. Now at last in IT sector this will give you a lot of its depend on your strength. In some cases if you have a potential then you can achieve in few years but in case you are a lazy person then IT sector or private sector will give you nothing and give you a lot of pressure. Finally i conclude this remove your confusion please select your future with your interest, every sector have good scope. Please improve my question and answer with your comment ?

different liquid detection sensor

I am building a biodiesel production system. at different points in the process, a tank will have different liquids in it (sometimes more than 1 type, separated out). for instance, there is a point where glycerol sinks to the bottom, while biodiesel floats on top. what i want to do is drain the glycerol from the bottom of the tank (via electronically controlled solenoid valve), then when a sensor detects a change in material (biodiesel), shuts off that valve and opens another (final product tank). for the life of me, i cannot find a sensor that will do this for less than $100. preferably, i'd like to spend less than $30. i can work with a resistive type or voltage type sensor. i just need to be able to make that distinction of material change... any ideas?

Difference between NE555P and 555CN?

I'm working on a circuit that uses two 555 timers. At the electronics store, they gave me a handful of 555 chips, I only noticed the difference when I finished my circuit: the R1 value is shorted out, my R2 value is 150 Ohms, and the electrolytic cap is 10 uF. (see the schematic with R3, D1 and D2 replaced with a single piezo speaker). The thing is, if I put in the 555 chip marked LM555CN, it appears to be 'always on'. But, if I use the Texas Instruments chip marked NE555P, the circuit works as expected, that is, it generates an annoying screech on a piezo speaker. What is the difference between these two seemingly identical chips? Is it a quirk in the TI chip that it works when R1 is just shorted out? And lastly, is there a way around this problem other than me sitting at the electronics store picking out the TI chips? Here is the date sheet of ne555p Also note - the piezo speaker doesn't have any oscillator in it, that is, when you apply raw power to it, it just clicks once and sits there, that's why I have the second 555 timer, and it's not an option to change out the speakers at this point.

A different water wheel design?

I posted this idea on the makezine forums recently and got 1 answer but it seems I did not explain what I meant too well so I thought I would try here to see what you think. See the diagram at http://www.nelliott.co.uk/maker/water-wheel.jpg Would this produce more power than a conventional water wheel? My theory is as follows: In the case of a normal wheel each bucket/segment when full of water has the turning power equal to weight of water x length of horizontal line such as the yellow one in the diagram. That is it's weight exerts a force to turn the wheel according to it's horizontal distance from the centre of the wheel. If instead of the normal wheel the 3 blue circles represent 3 sprockets.There would be a whole series of buckets attached to the red lines ( which represent a chain ).Water would pour into the buckets as shown, so it would simply propel the buckets vertically down.The turning power of each one of these would be equal to to weight of water x radius of large wheel. So each would have the turning power of the best one such as the line from H to the center of the wheel. As far as I can see this would mean a large increase in torque over conventional which I hope would easily offset the losses due to the chain drive. What do you think?
