Extremely small arduino using dip16 form factor?

I am looking for a extremely small arduino board close to this one that I have.-> www.anatools.com/anarduino-kit/ I want a smaller form factor and I dont need need the serial headers, or even the extended sides as I can solder strait to the headers. I tried making my own board using eagle, and diptrace but I am running into alot of issues making it so compact. I was wondering if anyone has already made a board and have to eagle files, or know of any eagle files that I can have so I can etch my own board. Any help would be great! Thanks!

Where to find a small form factor 12v Battery?

I am looking to build an LED light that can be powered directly by a 12v source or use an internal battery. I expect that the fixture form factor will be about 4" in length by 2" to 2.5" in width and no more than 3/4" in depth. Internally, it needs to fit two LED units (each draws 0.1-0.2amps and only one would be on at a time) that are 1"x1"x5/8" each, the inside component of a single pole double throw waterproof switch and the remaining space for batteries. I would like to fit the maximum amount of available capacity as possible in as small a space as possible. I am looking for battery suggestions - small form factor, 12v, preferably available via a regular source (i.e. don't have to be special ordered from China), low self-discharge rate, ability to withstand temperature extremes (specifically 120F-140F degree heat). I'll consider wiring up batteries in parallel and serial to get the charge depth and the proper voltage. Any thoughts? I looked at A23 12v batteries and 2CR-1/3N 6v batteries (wire in serial) but I'd like to find something with more available capacity. Also, I'd prefer a non-toxic battery, but will consider lithium, and the ability to be recharged would be a big bonus. I'm guessing there's nothing out there that would give me enough life to be happy, but I thought I'd ask. Thanks!

Hard drive price confusion

Looking to create a small form factor PC to fit on the back of a monitor and while searching for a hard drive on Newegg noticed that the lowest price 2.5" internal desktop hard drive was $120 and not even 150GB ( http://tiny.cc/01012 ) while a 2.5" USB powered portable hard drive that is 1TB is $90 ( http://tiny.cc/01024 ), these numbers just are not adding up, couldn't I just disassemble the portable hard drive. Not sure if I am missing something important, Help is greatly appreciated!

how effective is this airflow design? Answered

I am working on a very small build pc, and i was thinking that the best way to reduce overall height would be to design a cover piece that directs the airflow from the intake fanover the CPU and northbridge heatsinks and out the back of the unit via an exhaust fan. this method was chosen because the fan cannot be on top of the cpu heatsink because the unit would be too bulky if it was. I have attached a crude image of the planned cover and the layout of the board's heatsinks, and i would like to know if this is a effective method for cooling, in such a small form factor. if it isn't, what is?

A min-wind turbine tower possibly tree like form

Http://www.megagadgets.nl/en/products/minikin-wind-charger-p-1265/ The image above show the small windturbines I would like to use withouth the battery compartiment, or something like wise. with the stormy weather, I was wondering if a vertical colum 3 wide, and say 3,5 m high could not be used to generate electricty. I then thought it would be better if it liked a bit like a tree, have a tree shape. So that in the bottom 0,5 m there are no mini wind turbines, but at the top end it would have tree like shape filled with them, all generating there bit of power and adding that to a battery system. As I consider it possible that to much power could be obtained, so the excess power would go to a kind of art installation. I wonder how to fabricate such a small turbine myself, but also what windspeed it could have, and how much power each one could generate. e.g. could it generate so much power that it damages itself. It may not be the most efficient form as that a small windturbine would do the same, but in total it would be flatter and with a nice color i´d like them more. I don´t really like the grayish color of those big ones they build along the road. The idea behind it is that you can then ´plant´ a forest of them. The images are merly to given an idea.

can super caps be used with rotating magnet to form generator?

Rotate cylindrical magnetic bar over circular super cap as it's or short her 2 internal plate (hopefully if we can) to act like one flat ribbon coil nano wire made of carbon instead of copper. nano tech also should be implemented in small medium even large motor/generator and I think it would yield generator with high efficiency low weight and size with minimized edde current and inertia. NOTE ultra caps does not sold in our local electronic store here in damascus syria , if it was i would bought it's and experiment making generator using magnet and super caps and post the result thank you all for your time reading my question :)

Where can I find a (very) small auger?

For some reason, I have found it very difficult to find an auger that is 1" or less in diameter and is long enough for practical use.  I have needed such a thing for both a science project as well as an automatic feeder.   I have only found this part in the form of parts in toys.  One of the toys is a demonstration of an archimedes screw water lifter, which I have obtained but it's not long enough to be terribly practical.  The other is from an old toy grain auger that isn't made anymore.  Similar ones are still produced, but the augers are made of plastic and aren't entirely straight or flush with their enclosure.   The best one I've found is in this toy: http://i.imgur.com/8vVWJgG.jpg I'd like to know of any manufacturers that make augers similar to that, whether they be metal or plastic.  I'd rather not blow money on expensive antique toys and destroy them.

Prize verification

Hi Prize Room Guru, I think it would be a great idea to create some form of prize verification for contest and challenge winners. I've won a few contests, and each time I fill out the 'collect your prize' form I always wonder whether or not anyone received my info. Once I won something from the Big and Small challenge and my info was never processed, so I visited the HQ to pick it up (which isn't exactly a bad thing, but still). It's a small improvement, I know, but it would definitely put my mind at ease. I'm sure there are others out there who feel the same way. Thanks for considering this :) Lance

Any Way to Easily Obtain Deuterium?

I've had an interest in how physicists obtain deuterium for their experiments (especially those dealing with nuclear fusion).  I know it comes in small quantities in water, in the form of deuterium oxide ('heavy water') .  It also comes in the form of 'heavy methane' also.  I've looked at several patents dealing with extracting deuterium from such sources.  Is their any do-it-yourself (DIY) techniques that could use every day materials to obtain deuterium?

Why is it so bad that the small bakeries disappear more and more...

Everyone loves a good bread roll, a nice and freshly baked bread...But where does it come from and what is really in it?When it comes to bread and bread rolls we tend to think all is fresh, especially when you see that your favourite supermarket has a bakery with a real oven.Our local baker that took over the business from his father not only sees a thread but also is unable to compete with the price.The consumer only too often selects by price only if look and taste seem to be good.A bread roll for under 20 cents, a whole bread for just over $2 and I am not talking toast here...So how is such a price possible or how can a "bakery" provide 30 or more different types of rolls and bread with just one or two small ovens and a tiny kitchen area?The trick on a small scale is to use ready to go mixes, just add yeast and water and you are set to go.On a big scale we talk about dough that is frozen, sometimes pre-baked but alsways already in the shape of the finnished product.Since there is just flour, salt and yeast in it what could the harm?Like with soft drinks and alcohol not all ingredients are legally required to be listed.Enzymes, antioxidants, modifiers and more.The claim is that ingredients that disappear during the baking need not mentioning at all.If we check how these helping substances are made we get everything from bacteria and fungi over chemical compositions that are lab created and even things that are totally engeneered.Why use nature if you can made the substance in a lab...Most countries have authorities that deal with just these things and their use.So as long as every single ingredient is legal and does not require to be listed it is fair game.The problem here is that no one really knows what goes into the dough for these ready to bake frozen products.As we know from our chemistry lessons in school even totally harmless components can combine to a harmful endproduct.Especially enzymes are used to to modify everything from DNA over meat products to modifying the appearence and shelf life of a product.For most if not all the secret ingredients used we are assured they are conform with the local law and food regulations but we will never know where they came from or how they could interact with each other.Every dentist will tell you that cheap, white (so called) bread is pretty much the worst for your teeth.The usual claim here is that it is too soft, might contain too much sugar but in general the carbohydrates convert to harmful sugars and food for bacteria.These bacteria then harm your teeth...This alone however has shown to be a bit of a misjudgement.If you take the official ingredients on their own then their harm on the teeth is basically non existing.It is again the enzymes and their remains that do the hard work by providing the base to convert a lot of contents directly to sugars through these bacteria.If we now go a step further and consider that bacteria do a pretty good in our body to keep a healthy balance and convert nutrients for us we have to wonder...A thing of our modern time is alleries, same for intolerance to certain foods.The sources for these are plentyful but apart from shielding ourselfs agains all bacteria, viruses and germs in general food is a common factor.Regions with limited or no access to processed foods or drinks show little to no signs of our common allergies or common helth conerns like heart disease or obesity.When it comes to our bread products it is obvious that we consume a lot of it and simply trust the claims on the pack.Rich in omega 3 added fibres, wholemeal...A real baker starting shortly after midnight to produce fresh products for his customer will just shake his head.There are many studies that show us the quality of certain foods, also a lot that show how fast food is bad for you.But when it comes to investigating the bread we eat every day we only find meaningless informations.The long term effect of some of the "secret" ingredients in bread are however well studied in animal tests.Digestive problems, failing to make use of certain basic amino acids, an affected central nervous system and even behaviour abnomalities have been observed.Of course we can't really compare a rat or pig on totally overdosed tests with what we eat on a daily base.But if certain enzymes and other ingredients in our frozen bread mixes and also dry mixes can do this then it is safe to asume that some sife effects from long term exposure will happen too.An enzyme that might just cause a less sticky dough might also affect meat.Another ingredient that should keep the dough firm enough for production machines could cause your stomach lining to produce far less liquids that help digestion.And other ingredients that might just try to produce a more uniform expansion of the dough might break down other food products in your intestines so the body can not convert them into as many other building blocks as before.Sure, we trust the claim that the baking will totall remove all traces of all the things that are not required to be listed.But lab test will show quite opposite, especially when it comes to soft, fluffy "bread" in sliced form.Bread is one of the basic food items everyone needs, so if being able to provide it at an "affordable" price is possible than not too many will actually check the product as a whole.Imagine you buy a premium looking steak and on the pack it states it was made with meat glue - another enzyme.You would not buy it...Thankfully most countries banned the use of meat glues after to many cases of related food poisoning happened.Should have been obvious that cut meat will have more bacteria and that gluing such pieces will result in bacteria to grow inside the meat at fast rates.So if you now wonder why such things are not fully regulated and checked ask yourself: why do you buy the cheap bread from your supermarket instead going to support your local baker?Money...Don't trust my words here!Grab a bread from your supermarket and some bread rolls, then do the same at a real bakery and compare the products.After that check for the best time and grab a few cold beer to have a nice chat about factory made bread products with the guy who kowns how to make it.You might be suprised what he will tell you ;)

How can i focus a magnetron beam from a microwave , to make a small metal forge?

hello I have been looking for a number of ways to cast my zinc with, along with just melting other metals namely aluminium. I have come across the microwave method, however i feel that just using a microwave is a wasteful and hazardous means of meting metals like zinc , since the metal vapors are very flammable, even explosive, even as a dust I thought, since the microwave is basically just a box which the magnetron beams microwaves into, why not build a forge, which consist of a crucible laying in the center-point of a magnetron beam. all this would sit outside, done at a distance to avoid exposure to rouge microwaves. I dont wish to introduce anything new into the equation, just use prexisting things form the microwave, and probably some aluminium sheet. Anyone know if it will work better than just using a microwave? and how i should focus the beam? i want to keep the whole thing as compact as possible, probably which the crucible being no further than 10-20cm from the magnetron. Thanks

Is it possible to use a DVD player hardware / peripherals and convert it into a small "net book" style computer?

I have a "older" (maybe 2 years tops) DVD player made by Haier with a 7" screen. (Total width is about 8 inches.) My questions are numerous but can be sumeerized with this: Can I use the case, psu(battery), and LCD and rip the rest of the guts ot to make a small computer. Now granted, I know it won't be any kind of speed demon. I have built many desktop systems before. But insofar as laptop hardware is concerned I might as well call myself a complete beginner. My plan is thus (and if you would like pictures of the existing hardware and connectors I would be able to supply them): I would take out the mobo and the drive which is broken (my daughter burned the motor out when she was younger by manually moving it) and try to replace it with a smaller form factor motherboard. I would need this mobo to be able to boot from a usb drive so that I could use a bootable linux, possibly ubuntu, and maybe another usb drive for an input device. (Mouse most likely, use an on screen keyboard.) Another question would be are the connectors for the i/o in small devices standard or are they mostly proprietary? Would I be able to use the existing cables with a motherboard? If not are there converters? And the next thing would be that I would need a network card to work with it.... In the end, I would like it to be able to use a tiny linux, have some sort of i86 architechture (becuase flash 9 or 10 wont work with a powerpc arch.), and be able to use firefox to view youtube. It's kind of a gift for my daughter. Is it possible?

Looking for the smallest wide angle lens I can find

Premise: I have a droid incredible and I love taking pictures with its awesome 8MP camera.  I don't like its depth of field however.  I'm sitting here right now, looking at the camera enclosure, and I'm wondering if I might be able to pop open the red dome of the camera and slide in a tiny wide angle lens.  I've seen the cellphone wide angle lens kits you can buy for things like your iphone, and I actually did buy one for my Zi6.  Worked amazingly well, but even in that small form factor, it sticks out too far for me if i were to use this on my droid inc. Objective: I'm looking for an elegant solution that keeps the wide angle in the enclosure, and can't be knocked off or removed while in the pocket. How feasible would this be?  Would it be possible to find a small enough piece of glass that would give a wide angle view in such a small form factor?  I'm just guessing here, but I'd say the diameter would be 8mm and probably 2 or 3 mm in depth.  Thats pretty tiny... Anyway, I just wanted to get some suggestions from the DIY crowd.  I'll include some pictures of the camera's enclosure to take a look at. Thanks.

How to make Arduino triggered still camera?

I'm looking for a simple way to make a camera using Arduino with the following properties and behavior: -when a certain signal from a sensor or switch gets to the Arduino it takes a single picture and sends it to some kind of memory, preferably a large one that can hold a lot but is small in form factor like an SD card or USB stick. -the camera is always on and waiting for input, allowing the image to trigger immediately upon sensor trigger -the whole thing would work with a fairly small form factor Arduino board, shield, and camera module -obviously camera quality is important, something that would give a reasonably clear image within a fifteen foot distance and in a variety of lighting conditions without a long time taken to focus would be ideal. It seems like most guides I've seen are for video cameras with a ton of options or other inputs. I just want a stupid simple camera that only returns one picture for one input, with an on off switch.

What is the definition of "matter" according to the string theory? Answered

Hello!  I have recently studied about the string theory. Now what I have understood about it so far is that very small particles like the one's that make up neutrons and protons are actually made up of "strings" that vibrate in 10 dimensions at particular frequencies which determine the nature of the particles that they form. I also came to know that "strings" themselves are weird distortions of space-time.   Now I don't know if all that information is correct or not. So my question is that according to it, it would mean that matter itself is a distortion of space-time, is this true?

My big telescope project

I'm starting to design a very large telescope for my "backyard", ideally it will be a 1 meter (or larger) Prime Focus Telescope. I am in the process of engineering the primary mirror and have concluded that I need to create an array of small hexagon mirrors similar to the Keck Observatory but smaller. This will decrease the quality of the telescope but it will make the project affordable. The biggest problem with this design is that the mirrors have to be exactly placed and tilted to form the a perfect parabolic curve, and frankly I have no idea how to practically do that. If anyone has an idea about how this can be done or questions about my project i would be glad to hear from you.
