I am looking to buy or build a small voltage regulator that can fit in an O gauge electric train engine. It needs to have a 18-20 volt AC input and 10-12 Volt AC 1 amp output. I would like to buy one already built, buy a schematic or a schematic with the parts to build. Thank You

Hello everyone, I'm looking for a way to make (or hell even buy) a very small buzzer that can be rectangular or cylindrical that is 4mm in diameter and can be up to 10 mm long. I've searched on Digi Key for something this small, but most things are about 8mm in diameter and 4mm long. I need something skinny and long, not short and fat. Does anyone have any experience with this? Thanks

Hello all, Seems like this should be a good competition type project. Being a hiker and bicycle traveler, I would love to have a small, (read lite), solar panel that would keep my electronics powered up. The electronics would be, a phone, front and rear light or headlamp, a small 7" tablet, and maybe a small mp3 player. Ideally the output would equal that of a good USB port, 5volt and ~2amps. The charger for tablet states 2.1amps. Sorry I'm not dialed in what ideal amperage would be, but I do know that not less than 2amps, right? Anyways would love to see a competition among the peeps all dialed into this with the parameters stated above. I'm sure other parameters would be worked out too. If there's something out there in the real world that maybe you think would suit my needs, lets see what there is out there! Feel free to post up.

I am gathering the materials for a project, and I need a small digital camera.The lens must not move, images must be downloadable via usb, batteries must be charged via the same usb.This camera is ideal, except it is way too expensive, and is a video camera (and it's from China, but that's another issue).This camera is ideal, except that the batteries are not charged via the USB, which makes my project much trickier (I'm going to be building the digital camera into another object).Can anybody recommend (or at least find online) a "happy medium" between the two?

Ok I decided to rip into my tractor today because I was bored. I knew if I ripped into the actual cylinder that it would probably look pretty horrible with the way I drive my tractor. Needless to say I was right... I want someone to tell me what I can do with this!! I have it sitting open like it is in the pictures right now and I don't wanna put it back together until someone looks at it!. Also, how do I check that the valves are working right? Can someone PLEASE look at this asap?? Also does anyone know what I could clean the cylinder top and the cover with?? Would varsol paint thinner be a bad idea because of the gasket??

Hello all, could anyone give me some insight to how complex the process of designing a very small GPS tracker which could be used to track lets say a person, which can post its co-ords to map software which is custom programmed etc in realtime. Hypothetical scenario: 1) Tracking someone who is on the move outdoors, only has very small pockets to fit the thing in. 2) The device must send co-ords to mapping software on a computer every 10 seconds maybe. 3) Someone can view there position on the map software in instantly to understand their exact position. Also how expensive would the whole process cost to manufacturer roughly? Thanks in advance and sorry for the vagueness in my question

In the Site Updates forum, the goddess of code Rachel reported on last night's minor roll-out: I've just released a small set of changes: new footer featured and popular items are now split out by channel home page shows both featured and popular items in the same list searching on an exact channel name gets you to the main page for that channel various small formatting fixes I wanted to make some comments on two of these changes, both pro and con. The new footer is different, to be sure, but I don't think it's too bad. All the information is there, and relatively straightforward. Having the search box at the top and the bottom is a great idea! The extremely dark background is not very accessible, though. I think a pale grey (the same grey used in the header) with normal black text would be a better choice for our low-vision users. I'm not particularly happy with having the Featured and Popular stuff jumbled up together, and indistinguishable. Those two states are really different, and the have different implications for the Instructables involved. If you're going to jumble them up, could you at least put the nice Featured banner onto the thumbnails? UPDATE 23 Apr 2010: They've added the banner to the home-page giant thumbnails, and have created a new Popular banner as well. Also, many thanks to Rachel for fixing my very own bug! Now the masthead (and new footer) are properly rendered even when I use the horizontal scroll bar.

Nanotube Radio: Supplementary materialsK. Jensen, J. Weldon, H. Garcia, and A. ZettlDepartment of Physics, University of California at BerkeleyCenter of Integrated Nanomechanical Systems, University of California at BerkeleyMaterials Sciences Division, Lawrence Berkeley National LaboratoryBerkeley, CA 94720, U.S.A.We have constructed a fully functional, fully integrated radio receiver, orders-of-magnitude smaller than any previous radio, from a single carbon nanotube. The single nanotube serves, at once, as all major components of a radio: antenna, tuner, amplifier, and demodulator. Moreover, the antenna and tuner are implemented in a radically different manner than traditional radios, receiving signals via high frequency mechanical vibrations of the nanotube rather than through traditional electrical means. We have already used the nanotube radio to receive and play music from FM radio transmissions such as Layla by Eric Clapton (Derek and the Dominos) and the Beach Boy's Good Vibrations. The nanotube radio's extremely small size could enable radical new applications such as radio controlled devices small enough to exist in the human bloodstream, or simply smaller, cheaper, and more efficient wireless devices such as cellular phones....This is the site of the original article

I know Instructables likes Instructables to have several steps. I have a little project that really doesn't have enough to split into steps. It's more of a cool - you can do this - with an example. Is a single page Instructable ok? It's photo related, but craft would probably like it too. Should I just post it in those forums? Seriously - shorter than this post but with an image included. hahaha

Hey, I'm new here. I'm an established musician (composing is my focus). I've gradually decided I'd like to work on a new composition project which involves electro-mechanical instruments of my own design. I have a decent understanding of electronics, and I don't think the mechanical designs will cause me too many problems. I've had plenty of experience in building hobby stuff - remote controlled planes, etc. What I don't know much about is where to source mechanical parts. Electronics, no probs. But things like wee little cranks and levers, hinges, etc, etc... stuff I'd rather not build from scratch but you can't exactly find in a hardware store. Any ideas? (I know this is off the wall). Many thanks! - Tom

So I'm trying to create an LED ring, to where if I squeeze my finger the led will come on with a push button, and squeeze again to turn it off. So I bought a small series of LED's and Push Buttons from Radio Shack, but cant get it to work the way I need. I found that the push button switch was for a circuit board or something. Bear in mind I'm not the best with this type of thing but I thought I could figure it out on my own. This setup is supposed to be small enough to fit in a ring, so the smaller the better. Any advice would be greatly appreciated. Thanks

Hi, I'm trying to sand fairly small wooden objects that are about 1/2"x1" and sometimes a little larger. I often find that one side is thicker than the other or the corners are no longer perpendicular. I am trying various techniques, like taking a chunk of 2x4 and wrapping it sandpaper and then vice it to my workbench. Then I rub the object against the paper block. That is getting better results. I've read that some people use spray-on adhesive to secure sheets of sandpaper to a granite top and that it is supposed to work well. There are a few instructables that explicitly talk about sanding and I've read many of them. They advocate a bunch of techniques. I'm wondering what other folks have had success with. Thanks, Andy

Hello everybody it's been a long time since I have posted a forum topic on here but I just built a a new KNEX rack and pinion I would like to so everybody. The only other rack and pinion on Instructables was made by Killer~SafeCracker but it was huge and not to practical to put into a model. So here is a new rack and pinion that I made and it's way smaller then the one built by Killer~SafeCracker. The secret to this design is that it' uses a Micro KNEX to build the rack. I think there is a lot of neat things that could be made with this so please tell me what you come up with!

Greetings, fellow Instructable subscribers. My name is Ron, and I am interested in building a 'remote finder.' A little background about myself: I have little to no technical experience with building and/or programming. I am a complete novice. However, I am very eager to learn how to make my own nifty little gadgets. My first project idea is as follows: I would like to make a tiny device that I could adhere to any small electronic device which could easily go missing. Ideally, it would make a high-pitched noise and emit a bright light which would be seen assuming that it was, say, under the couch. It would also be paired with a remote control which could be put on a key chain. I've read through a few different tutorials here involving Arduino and 555, but I'm still not wholly sure where I should begin this endeavor, or how to make the device as small as possible. So, good people of Instructables, how would you recommend I go about creating this device?

So my new major has me in a machine shop that is at my disposal. I have made a few shift knobs but with living in the Northeast it can get cold in the winter months. I want to heat the knobs, which means finding something that is... - Small enough to fit inside a roughly 1" dia cylinder, depth minimal. - Quickly heat the knob - But not over heat it - Run on a 12v standard supply - Minimal cost I have considered trying to find a "Heating Element" but am unable to find such in a size I need and within a price I want. Maybe a soldering Iron element? I tried "Peltier" but they all are over-sized and debate the conflicting effects of hot and cold. However if figured out I could flip it for summer. I debated running a resistor/other electronic component with just enough power to cause it to heat up, but am worried about it breaking. I wanted to do a high power light bulb, but don't see that working as well as I plan. So I am kinda at a loss...if you have a specific item you can link me to let me see it, or just let me know of an item I can use.

I'd like to make a cheep motorized actuator using a long bolt, nut & a small hobby motor to spin the bolt. I like to know how to attach the small motor to the bolt, or some way to spin the bolt. All I can think of is drill a small hole in the bolt, then J/B Weld the motor on the back. Is their a better way? Not only that but, what do I use to mount the motor at one end & the other end of the bolt to spin freely.

Recently, I had complained about my abnormally small throat. Well, I just wanted to say... it has gotten so bad to the point where sometimes I have trouble BREATHING. I cannot swallow properly sometimes, and even FLUIDS have trouble going down my throat. Well, they don't get stuck like food, but I can feel them go down my through extremely slow. I am scared as hell. I am scared to eat. I am scared of choking again.Just a few days ago, my mom, dad, and I had pizza for dinner. I only had 2 slices of pizza. Both my mom and dad had 3, maybe 4 pieces (they were small). My parents were done, and I was still halfway done my second slice. My dad is taking me to the doctors either this week or next week. Please, tell me what you think and if you have the same problems===============================UPDATE============================= My dad is taking me to the doc tomorrow. I am excited, even though they may shove cameras down my throat, haha. When you see this topic has "Triple update" I will tell you what the man in the white suit said.

Let me just get it out of the way, I have a genetic deformity. My Esophagus is VERY small. Mashed Potatoes get stuck in my throat (without choking though,) So today, I was looking forward to going to Wendy's for the first time in 3 months. So, I took 1 bite of my Spicy chicken sandwich... Swallowed, and took another bite. As soon as I took my second bite, I felt the first bite get stuck, so since it happens when i eat ANYTHING, I don't panic and take a drink of my coke.... I forget about the food stored in my cheek. The stored food in my cheek goes down my throat with the coke on top. I am in serious pain, and my breath is so short, I barely had enough time to *I can't breath*. My mom tells me to put my arms in my air, so I do. My dad come up behind me and squeezes my stomach... the food that I was choking on kept flip-flopping between my windpipe and throat. Finally, It gets out of my windpipe and into my throat... I run to the bathroom... I belch up out 4 mouth fulls of chewed up chicken sandwhich and coke. The chicken was stuck in my throat (but not choking) for about an hour. Finally, I decide to drink water and it slips down my throat... Now, I feel like I am learning to eat all over again. Everyone wanted to go to a diner at 10 pm... so I go, scared to eat (odd, huh?). I get the grilled cheese with a pickle and fries. About half an hour later, everyone is putting their food into boxes to take home... I haven't even touched my second half of grilled cheese. I chew everything into applesauce - like cider. Luckily, my dad, who also had this problem as a child, has a doctor who stretched his throat out, and when I get older, I will get that done to me. My mom and brother laugh about my incident... but now, I am still in shock and having trouble eating...

Hi guys, I've been thinking. Really thinking. I recently found my Digispark (if you dont know what those are, google digistump, click on the first link and go to products, Digispark. They're really cool.) and decided to put it to use. I have always wanted to have/build something like a micro gaming system (sort of like the ben nanonote (if you don't what that is, google it, its really cool)) and decided that as a challenge, I could try implementing the Digispark as the Processor. I know that I wouldn't be able to run any games more advanced than pong, breakout or snake, but even those kinds of games would be enough to keep me interested while in boring situations. My basic thinking is this: There would a small lithium-ion rechargeable battery on the bottom to be a base (but still removable), the Digispark without any headers above the batteries, and a small LCD screen (1.8, 2 or 1.3 inch screen size) that would have either two pushbuttons (one on either side of the screen) or four pushbuttons configured in a D-pad style on the right side of the screen (how many buttons it would have depends on how many pins the Digispark would have open (if any), which also leads to my question, does anybody know any place to get video LCD screens (don't care if its color or not) that only take up 4 or less pins? I know that probably seems absurd, but if anybody knows any places to get them, please let me know. And just one last thing, is it possible to program games in the arduino IDE? Are there libraries for them? ANd if you can program games, just how advanced can you go?

If been wanting to film some of my Rc flights iv been thinking of two ways to do this: A.) buy a mini camera (not wireless could cause interference with other planes or mine although it should only affect 2.4GHZ or spreed spectrum channels which are designed to handle this kind of interference but i dont want to cause any accidents) or B.) Buy a cheep digital camera and mount it to plane Things to consider:Any thing will add weight to the plane which will affect balance (to solve this add weight till balance)I want to avoid wireless. How to power; battery's weight a lot and take up lots of spaceDragSize of cameraIf i do use micro camera where will it record too?Dose any one have any suggestions or ideas on the best way to do this on the cheep?Original form (it was origanaly posted in that group but it got separated) *update* i found a Camera called the flip video camera it has every thing iv been looking for its cheep about 150$, has a tripod mount, records 60 min of video, comes with editing software, runs on 2 AA batteries, and has a small (1.5inch) Lcd screen

Hey, I'm guessing this isn't a problem something that is only troublesome to me. You see, I am not allowed any pets, but you know, I am planning on adopting a couple of rats. (yea rats!) I need to make a cage which is hidden/camoflauged. It will already slightly be hidden and I'm sure I can arrange furniture in a way to conceal further. The cage needs to have air flow freely, made of plastic or coated metal, have a way to easily clean it, and it has to be escape proof! (no wire floors though, how ghastly) The rats I will aquire will be babies, about 4 weeks old. If they are males they'll get to be about 2 pounds and about three feet (including that wonderful tail xD) In a year. I live in an efficiency apartment, so I can't hide them in a closet (and if you ever seen a rat reaching out to grab the rapidly diaspearing light you wouldn't want to anyway) My best bet is "walling" off my room (which has the only bathroom) with a curtain, rearranging the furniture, and of course have a clever disguise! My first attempt (I was merely fostering these guys, their owner got evicted) was a storage drawer bin, I sawed off the back of the first drawer (and was planning on expanding throughout the set) and stapled in chicken wire to help with airflow. The fact that it was a mostly plastic drawer made it easy to remove and hose down quickly. I also sawed a little hole to hold up their water bottle which is an absolute MUST. They will knock over water bowls, sit in it, and most crazy of all, stuff bedding in it to absorb it. The main problem with this set up is that of course, you can see through it and see the little guys running amuk. I placed a blanket halfway covering the front and covering the sides, but Jackie decided that he was bored and pulled it all in, thusly exposing him and getting him caught `_` It lasted 2 months and I got them into a new home anyway. So! I'm sure I'm not the only one who has to hide a pet/pets dwelling! Does anyone have ideas??

Hi! ive been working on a mousetrap car for my physics class and i was looking into the idea of pulleys to get more power to pull on the axle to rotate it. Ive noticed that alot of the Pulleys I see all rotate on an axle which I can not acheive due to the small space on the car. So my thought would be to anchor these small wooden pucks (small like 1 cm diameter) and have notches in them so that the fishing line wouldnt slip. (picture) Can I get some help on wether or not this would work? If it works can I get some input on how i could make it better? ex. different pulley designs that dont require moving parts. Thanks in advance!

I want to build a battery charger that is capable of charging 12v (2x6v) of NI-Mh PCB type batteries (varta packs from farnell) . I think the batteries are button types bound together. The input will be from a small 1" diameter motor spun to give 12v out (I assume this is a dynamo). The output from the batteries needs to power : a 12v wireless reciever (6mA standby/66mA switching) a 12v - 24v dc/dc converter powering a solenoid at 25mA@24v. I have seen a 12v charge regulator in Maplins but it is designed for car batteries. If I send the 12v motor/dynamo output to the charge controller and then onto the batteries will they blow up? As I am a mechanical engineer this is new to me so can anyone help ?

I would like to make two key fob sized units that if brought within ~20cm of each other would sound an alarm from one of the units. I've seen a pair of key fob sized RDIF alarm tags that sound an alarm in one if moved more than ~10m apart. They sell for ~$50 US but I need something that accomplishes just the opposite from this device. I want to keep two pets away from each other (one bullies the other) and such a device would I believe accomplish this task. It seems like it should be relatively simple to design but I'm an artist and machinist and know little about electronics. I purchased a book entitled Practical Electronics for Inventors that has given me some knowledge about the basics of transformers, relays, capacitors, resisters, etc. but nothing on IR or RFID transmitters/receivers. Everything I read about RDIF is geared towards one stationary reader (or large hand-held unit) and one or more transmitters. I made one collar with an IR receiver from an R/C car and a small piezo alarm that would sound when I pushed a button on a remote. This works but only if I'm in the same room with the offending animal. I need something that works when I'm away or the animals are upstairs or in another part of the house. They are indoor only pets so the device need not be weather-proof. Anyone with knowledge of such things want to lend me a hand?

Now that it works again, I decided I should put it into something really cool. I had a dead curtis rcd847 cd player, and a motherboard that would fit inside it. I have everything that is needed for it to work: 256mb ram, a power supply, keyboard and mouse, a hard drive, etc. now i need help figuring out how i am going to get the power supply, hard drive, and maybe even a cdrom drive into this cd player. this is the point where i am asking for some help. i was thinking about making a base for it but are there any other suggestions for how do go about it? PS: the first picture is the motherboard, the second the power supply, the third is all of the bad capacitors, 4 and 5 are the cd player shell, and the last one is the hard drive

I am..... not very good with electronics. ill admit it. but i still love that feeling when you do something and finish and it feels perfect. and i really need some help. i have been looking everywhere in my town and nobody has any nixie tubes (probably because they are so old), and they are really expensive on places like ebay. i also have no clue how to work the pins, and how i could get such a high voltage. and make it all into a watch. and to make it small. and to keep it under 30 dollars. what a mouthful. So could you all just list where you get your tubes, how you wire and program them, and how you even make a portable and practicle power source? i have been looking into the disposable camera power source, but that is already kinda big. when done i will have a leather/metal gauntlet to wear on my arm. it can take up about half of my forearm. can this even be done? i dont have an arduino, but i have a basic stamp, but its not good at keeping time, so thats out. please list your help and ideas below. and your knowledge is greatly wanted!!!

Hello, I am looking for a supplier that sells metal tubing, steel, very small inner diameter with threading inside and end-caps that screw on to make it flush and appear as a solid metal rod (rubber O-ring if needed to keep dry). I am attempting to make paracord survival key fobs. I want to fit various tiny survival gear inside the tube, closed on both ends then weave the stitching around the rod. When needed the user can unravel the paracord for use with what's inside the tube. It must be tubing because one of my ideas is to put thermite inside a tube, wrap some magnesium ribbon around the outside, then stitch the fob around that. Other ideas include other types of survival gear but that one will be my fire starter fob. :) The rods would be about 2-3 inches in length, wall diameter thin but sturdy, inner diameter maybe 1/4 - 1/2 inches. Thanks for any help. Rounded end caps would work fine as well as they would give me more room to stuff things in, but I need access to the suppliers for both the threaded tubing and end caps. :)
