help on mutiple steppers on arduino mega

Hello, I am hoping to get some help for my project here. I have three steppers that would like to control using an arduino mega 2560...my first question is: is this possible? in other words can i connect the wires from stepper (bi-polar and 4-wire) directly to the arduino pins? secondly, is there a sample code that i can use to make the steppers sweep independently? are there specific libraries i need to use? Regards, Behzad.

How would i build a cheap wireless theatre comms add-on, possibly using phones as the wireless component?

My school theatre has a Jands Ezicom (i think) comms system but its all wired. My friend and i were wondering if its at all possible to make a DIY wireless add-on. We had the idea of somehow interfacing some cordless phones into the system and using the conference capabilities of them but obviously this presents some problems with voltage/impedance/whatever else. Its also just a personal thing so A) only up to 2 wireless devices would be needed max, and B) its self funded so cheaper is better. If anyone can offer advice or ideas its all welcome.

Sennheiser audio question?

So I've owned a pair of Sennheiser HD555's for about 4 years now and while they haven't broken in any way, I'm looking to buy another pair of Sennheisers that are more portable than the HD555's (10 ft. cable and bulky 1/4 inch jack + open design -_-)   I've been considering 2 choices in the Sennheiser 400 series.  The HD439's and the HD449's While I know they are both very similar, there are big differences in my opinion.   HD 439's: I really like the detachable cable on these, and I've always been in love with the cloth ear pads from my 555's, so i know these would be super comfortable.  Also these present a bit more bass than the others in the 400 series, which i don't know if I'll enjoy, because I really only have the HD 555's to compare audio quality to. HD449's: These headphones are apparently a bit more powerful than the 439's because of stronger magnets in their monitors, which is a plus because I mostly listen to music on my laptop, phone, or zune (YES I SAID IT AND I SAID IT PROUD--ZUNE).  Also I'v e heard that they have a better range of sound quality not just regarding the bass and treble.  The one thing that scares me to death about these cans is the pleather or "leatherette" material for the ear pads.  While i know that these are better at blocking outside noise, I can't help but feel like they'd be very uncomfortable.  The only other cans i've used with the pleather are the Bose AE2's, so one question is how do they compare? also to beats leather pads? In general, I listen to a broad range of music from classical to rap to indie rock.  Pretty much anything but country.  I like to have a bit more bass and high tones than mid, but not too much.  For this reason, I think the HD439's would be better in regards to sound quality and better design/comfort.  The only thing that keeps me looking back at the 449's is the offer of more powerful magnets and better sound when playing from a mobile device or something with a low power output.  I also really like the fact that even if i do like lows and highs better, I can always put an equalizer on the HD'449's to tailor their more balanced sound to my wants.  But I'm still afraid of the comfort the 449's offer compared to the cloth pads of the 439's.   Again I own a pair of Sennheiser HD55's and love their sound quality and comfort.  I also own a pair of AKG K181DJ series, but those are mostly for listening to house, dubstep, and drub&bass.;  I've owned the Bose AE2 (second edition) and have used beats studio for a time.  These are really all of my reference points for sound quality and comfort. Anyways, I digress.  I'm very torn between the two and I've given all of the info I can.  Any suggestions/ratings/opinions would be greatly appreciated.

How can I build button panel that produces sound clips? Answered

I am tying to build a panel with approximately 30 buttons (I would like the buttons to resemble door bell buttons). When a button is pushed a sound clip is played through a speaker. I would like one sound clip assigned to each button rather than a random sound clip. If the sound clips were randomized there would be no need for all the different buttons. The large panel of buttons is an esthetic that is important to this project. Thank you for any advice.

Zip Review

Alright, so I just made JonnyBGood's Zip Mk1 today, and decided to do a review on it. I recommend that before you make this gun, please read my review as some of your questions may be answered. So without further adieu, let's start. @Range- Not Bad, but cannot be termed as good. It is VERY inconsistent as well. The range that I got with one rubberband on this gun was  5-20 feet. It is quite good for its size though. 6/10 @Looks- The looks of this gun is awesome. It looks really 'sci-fi'ish. 9/10 @Durability- Really strong and well built, does not break easily. Point to be noted that the handle-stock(ish) connection is flimsy, needs some work, but I can live with it. 9/10 @Pieces- The piece count of this gun is a bit too high for its size. And not to mention the 3 broken rods. 8/10 @Comfort- This gun is very comfortable to hold and will not hurt your hand. 10/10 @Rate of Fire- Well, a 3-4 shot gun can not have a true ROF but if the hopper was extended, it would have a helluva ROF. No marks as stated above. @Functioning- Almost perfect functioning, but I guess the blocking mechanism fails sometimes, but rarely. 9/10 The Verdict- 51/60 (pretty solid) It is a well built gun that could use some polishing but in the end, it could be one of the BEST secondary gun there is or even a nice primary. The gun overall is cool and I would suggest you to build it! Also check out JonnyBGood's page and his other stuff! Note- These are my views of the gun and if you think that I am wrong at some point, comment or PM me! Hope you enjoyed the review!

Apart from the obvious things like an led, battery, on/off switch, wires and solar panel will I need some sort of controller for charging the battery as well as not overcharging it?  I'd like it to have a 1W panel, a 1W led and battery which can run the light for 5 hours (so 5Wh right?) If it is easy enough I would like to build one which has a USB port as well so I can plug in my USB fan. Thank-you for reading.

How do I make custom tablet nibs?

Back in October, I purchased a Genius EasyPen tablet. It only came with one tablet pen nib. It has lasted quite a bit, I guess, but I have noticed it is starting to reach its end. I have tried to buy some tablet nibs from the Genius website, but I couldn't purchase them for some reason. I guess the website's down or something, but I really can't wait much longer. I use my tablet quite a bit, so it would be a HUGE problem if I couldn't use it because I couldn't find nibs, so I thought I would make them. I heard you can make them out of toothpicks, but I don't know how to do it properly. Does one have a tutorial, especially focused around Genius pens? I would be forever grateful if someone would help me!!

To see the button, hover over the image you want to pin.  Don't open the image.  You can pin the big images, and the images that are in rows of two.  Any more images in a row than that and it doesn't look like you can pin them. Click the Pin It button. This will open a new tab the same as the bookmark bar Pin It button works. Pin the image. Close the separate window. You are done! Please, PIN AWAY!

12v LED lamp+ Solar panel+ 12v car battery? Answered

I am new to electricity beyond a basic circuit, so I am at a point of being unsure about my current scheme for a relatively bright light that runs off a battery which recharges via solar power and doesn't go dead due to the continual recharging during the day and effective use of electrical energy. I do not know whether resistors, transistors, power inverters, or any other equipment is beneficial or necessary. I am also unsure of a high quality, relatively cheap solar panel that is compatible with the 12v battery and the 12v LED bulb (if anyone has any advice for that). I drew up a diagram of my possible setups, labeled 1, 2, and 3. Option 1 is the basic setup without any additional hardware. Is one of these setups correct, and the most effective way to go about my objective? If not, how can I modify it to be the proper setup? Thanks :)

how to power multiple fans from a laptop? Answered

I'm currently working on a laptop to somewhat of a desktop conversion.  The laptop has really bad cooling so i have drilled into the case and added some big fans.  Its probably overkill yes, but if it works then who cares.   I've added two fans.  One is a 24V DC .20A fan and the other is a regular DC motor.  I'm wanting to power them from the laptop.  I'm not sure how to do that though.  I've tested them both separately on a USB and they are very slow and almost useless.  Is there a way to combine two USB ports for more juice?  Any ideas or suggestions?  Thanks.

I'd Like to hit the 1420Mhz mark approximately but with little electrical engineering or architecture experience, I'm not certain how? Which might make a TV easier to get there as UHF covers that right?

Connecting Two Water Storage Tanks

There was a similar post to this one a couple of years back, the difference being that both my tanks are filled from separate branches of the same supply using a ball valve in each tank to stop them filling. I then have an outlet from both tanks connected together that then goes off to a pump. One tank is 5000 litres and the other is 3000 litres, currently the larger of the two is redundant and its outlet valve is off, but come the summer i will need to introduce the second tank. I am located in southern Spain and in the summer they turn off the water supply to save water hence the tanks. My question is as the tanks are of a different size, if i were to fit the smaller tanks outlet with a non return valve so that the larger tank can not fill the smaller one via the outlet pipe, would this work i.e. would the joint outlet pipe still feed the pump correctly or would it have more or less pressure. I appreciate that i could balance the two tanks, but i would much rather be able to use all the volume i can. Many thanks.

questions about homeschooling

1. Where do I find curriculum? There are several options for finding a homeschool curriculum. One of the best ways to find out about what curricula are available is to ask other homeschooling families. Each will have their own favorite curriculum or combination of different curricula. Some families go to homeschool conventions where curriculum vendors present the best of their wares. Other families search the internet for all or parts of their instructional material. In states where a free, online public education is offered, the department of education might even provide books, materials, even use of a computer. Libraries are a great source of educational material, especially where literature and history are concerned.  For early elementary students there are many sources for basic math, spelling, and penmanship worksheets that can be printed from the internet.  Don’t forget to include educational games as part of the curriculum for everything from multiplication tables to spelling and keyboarding games. 2. What if I can’t teach a subject? Not every parent will feel comfortable teaching every subject.  While most parents will feel comfortable teaching the basics to younger students, when it comes to advanced composition, calculus, or chemistry many parents feel like they are not qualified to teach their students. Other courses such as foreign languages or music instruction often require more teaching than a parent might feel comfortable with.  The answer to this dilemma is to out-source.  Check with local homeschool support groups to see if a co-op offers group classes.  Check with the library to see if they offer courses.  Many times college students earn money through tutoring so check with your closest college or university to see if tutors are available.  Often checking with fellow homeschoolers will show a need and you might join with other families to fund a course.  There are always people who are willing to pass on their knowledge, some for free, some for a fee.  Ask around!

What's the best way to sand and spray paint particle board?

Hi All, Trying to make replacement bases for my floor-standing speakers.  The originals were made out of particle board and appear to have a black spray-paint finish.  They were destroyed in the post when the person sending me the speakers failed to package them properly.  I now have the particle board cut to the right shape and I have begun the process of sanding.  It is my intention to spray a primer on, sand, spray a top coat, and then spray some sort of finish.  so here are my questions: (1) I have sanded the board down with successively finer sandpaper and finished with 1500 grit wet and dry.  This is a very smooth finish until you wipe away the dust at which point it becomes rough-ish again.  Having done a bit of research I am now concerned that I have sanded the board down a bit to much, some forums suggest taking the board down only as far as 250 grit before spraying on the primer.  What should be my finishing grit before spraying on the primer?  My assumption was the finer the better but I'm not too sure now.  If the finish should be fine then how do I remove those stubborn fibers? (2) what type of spray primer works best with particle board?  There seems to be a multitude but most of the information related to car/auto body work.   (3) what grit of paper should I use on the primer? (4) what should I use as a top coat? Much thanks in advance Ross

laptop graphics card, custom heatsink or other compatible heatsink? Answered

OK, I have a Dell XPS M1710 that has an overheating issue.  I have done the oven re-flow around six times and it works, but it will eventually keep dying.  I'm afraid that the card has finally come to its end but I'm willing to give it one last attempt.   I'm going to attempt to convert the laptop into somewhat of a desktop.  I'm going to get a large heatsink for the CPU and hopefully find one that will fit the graphics card.  I'm hoping that with better cooling the graphics card will stop going out on me.   I have found a heatsink that i believe will work for the CPU but I'm not exactly sure I can find one for the graphics card.  I'm not even sure if it's possible.  If it is, that would be awesome if anyone could find one.  If there isn't, however, does anyone know another option?  Maybe, 3D print an adapter and connect it to a heatsink and then throw a fan on it?  Any suggestions?  The problem I have is that the screw holes on the graphics card are in a rectangle rather than a square.  I'll try to provide pictures to show what I mean.  If you need anymore I can get those to you.
