Battery pack rebuild

I read the instructable on rebuilding the 14.4v cordless tool battery pack and I've done it before with a decent Milwaukee battery. Now I have one that the thermistor is shot. It said 6k8j on it. It was a disc like an advil pill with two leads. Where would I find a replacement? I've looked on but can't make heads or tails of it. I imagine you would want it to stop charging at 70 degrees c like a lot of r/c packs do.

Robot that rebuilds itself after kicked apart

As this video of a modular robot re-assembling itself after being kicked apart by its creators at the University of Pennsylvania shows, the day is soon approaching when even smashing apart our rebellious robot slaves with hammers and axes will not prevent each individually severed body part from crawling towards you across the room, a murderous and autonomous agent of servo-controlled musculature.

How many actually recreate my instructables?

Every author, contributor, maker on Instructables ask's early or later this questions: Who and how many are actually rebuilding my instructables?  How useful and clear was this Ible for the rebuilder? What improvements have been made? After 5 years and 10 instructables further, I don't have an answer. There is hardly any feedback to answer my main question: How useful is my effort to publish my projects in a way that people can rebuild this (instructable)? Who are the rebuilders? I am a teacher who does not know his pupils. Or more clearly, a writer who knows how many books are sold, but who does not know if they are also read. Some people say in the comments they go to make the project and after that you hear nothing more. How is this for other authors on Instructable? It is legal to have thoughts about this side of the authorship. When it is not for my own joy and curiosity that I make and publish my project's for who else do I make this effort? Maybe the team of Instructable's can initiate a contest for the best reproductions of published instructables. Maybe one of mine is chosen ;-)

"Before and After" Pictures

This "Fix And Improve It" contest, and many previous Instructables, has me thinking that it would be fun if  there was an option to split your first picture into two.  Show a "before" and "after" in the same space.  The idea has some limitations for instance, showing large room sized pictures would make the thumbnail too small, but I believe smaller projects would benefit from being able to show both aspects at once.

Rebuild and reuse?

I was just thinking today. I want to get a soldering gun with a desoldering bulb or some kind of device to suck up solder so I can remove parts. I have nearly heaps of old computer motherboards, video cards, ram, and all sort of other things taking up space. And I'm not talking like pentium 3 or old p4 parts, more like P1 and even a few tandy and 486 parts kicking around. I've seen people making earrings and wreaths out of these old parts, but I'm thinking more practical, like what could I be building out of these components. I've never really gotten into things like pic programming and building things on bread boards, however I do have the know how to operate a soldering gun and I wanna get into these things. Could someone point me in the right direction or point me to a forum at least?? It'd be greatly appreciated because I really need a new hobby to do in my spare time instead of blowing my amps.

Rebuilding NordicTrack ski machine drive rollers

Many people still buy and use a NordicTrack Ski Machine, although these machines are not as popular as they once were. I have talked to people who say they just plain wore out a ski machine. The part that wears is the one-way clutch inside the drive rollers. NordicTrack makes the one-way clutch sound very mysterious. In reality it is a one-way needle bearing and is available from Amazon or locally from a good bearing shop. The internal diameter of the one-way needle bearing used in my machine (Challenger, similar to a 303) is 5/8 inch. The outer diameter is 7/8 inch. The width of the one-way needle bearing from end to end is 5/8 inch. I originally had hopes of being able to install new one-way needle bearings, myself; but, they together with the bronze sleeve bearings on either side of the one-way needle bearing inside each drive roller are pressed into place. Pressing bearings is not a job for the average home tinkerer but requires a bearing press capable of exerting tons of pressure in a very precise manner. You can often have a local machine shop press the bearings in your machine's drive rollers. Or, you can send them away to Nordic Track Guy and have them rebuilt for about $33 with a one week turnaround. The core of the rollers really does not wear out, but new rollers are available on the Internet from $65 to $95, depending on the vendor. From what I can find, some models used an alternate size. Check to be certain you order the correct rollers, if you choose to replace. One of my drive rollers suddenly began to hiccup. It seemed that the clutch did not always release immediately when I pulled my foot forward. Then I noticed a little mush in the response when I began to bring my foot back on the push stroke. Before you rebuild or replace your rollers, try this: Remove one side of your Ski Machine. See the second photo and check the exploded diagram in your manual. Four nuts and two screws, all plainly visible, need to be removed. Slide the washers and the roller off of the top side. The shaft and flywheel can be wiggled out of the other side without removing anything from that side. Remove the washers and the roller from that side, too. Flush the one-way needle bearing by squirting some penetrating oil, like Liquid Wrench, into the bearing. Work it both ways with your smallest finger. Push a facial tissue into the shaft hole in the roller and sop away the penetrating oil and any metallic dust it lifts. Do this several times. Let the rollers air dry. A little lubrication is good. People who comment on lubrication for one-way needle bearings use Tri-Flo (I am not familiar with it.) or they use a little ATF transmission fluid. You want enough to lubricate, but not so much that the bearings slip. (But, see the comments below where the oil impregnated bronze sleeve bearings are supposed to supply enough lubrication for the needle bearings.) Put the rollers back in place on the shaft. Check to be certain they grab on the rearward stroke and release on the forward stroke. Reassemble the machine. Do not forget the washers between the roller and the side board. My machine works again as it should. The day will likely come when this simple fix does not help, and I will need to rebuild or replace the rollers then. But, for now, my rollers have a new lease on life. What follows is for your information. The first photo is of a portion of the back cover of the manual that came with my machine. It shows a cutaway image of the drive roller. The black printing is mine. Notice the three cylinders inside the drive roller. The outer two are bronze sleeve bearings. The center one looks like a roller bearing, but is a one-way needle bearing. A one-way needle bearing is essentially a roller bearing, but the rollers are able to move forward and backward a little in their cage. There is a wedge shape for the axle of each roller that causes the rollers to bind between the bearing cage and the shaft when the rotation is in one direction, but they are free in the other direction. Here is a description of how they work with graphics. This link is for an Instructable about a number of modifications I made to our NordicTrack ski machine, including how it can be stored vertically in a closet. If you do not have a digital monitor for your skier, or need to replace one, here is an Instructable on how to make your own from a digital bicycle speedometer.  Check NordicParts for any parts you need, also Nordic Fitness Ski Machines. Danny at Nordic Fitness Ski Machines has some very nice new rollers for sale.

Vintage/Classic/Antique/Old Motorcycle, Scooter, and Moped Parts Sourcing?

Does anyone know a good source for obsolete parts? Finding parts for my '72 CB175 is proving to be fairly easy, however, the 1970 Harley M65S (leggero) by Aermacchi is proving much more difficult. Right now I am looking for a Carb rebuild kit for a Del'Orto ME18BS, I am sure there will be others later.  If you know where to hunt this down please let me know. Also, I think it could e useful to have a list of good vintage/odd/old parts places for other people fixing, building, or rebuilding bikes and scooters.

Does anyone have the circuit for these batteries please ? There is a temp overload (bimetalic type) and also a two diode (? zener) + resistor in series that I presume identifies the pack (voltage) to the charger.  I have burnt out pack that I have new cells to rebuild but not certain about the connection / values for those parts.

I'd like to challenge everyone here that makes useful things.  I'm rebuilding an old light fixture and I'm focusing on efficiency.   My challenge is to get the highest amount of lumens with the lowest number of watts.  I'm stuck and I'd be willing to put a cash prize on this. I'd like for everyone that gives this a try to stick to DC voltage.

Lawn mower blade hub.

I'm trying to figure out how to get the blade hub off of the bottom end of the crankshaft on my TroyBilt - Honda powered mower. There is no set screw that I can find, and it doesn't appear to be a thread off. There is a key, but I can find nothing that suggests how to get this thing off. I need to take it off so I can change the bottom crankshaft oil seal. This is a Honda GCV160 engine. Thanks for any input.

why am I not in the contest?

I don't understand why my instructable, the sphere lamp, isn't in the coffeecup contest anymore. Is it because of the use of plastic cups? Because as I mentioned it was intended with paper cups but I didn't had those available. If so, why didn't I got the message about disqualification at first and are there other instructables in the contest which only have plans about using paper cups but no cup was used? Will it help if I rebuild it with paper cups?

Outdoor water to silence homemade pump

Hi Guys, I love this website. I've been living in Egypt and can't really do all the hobbies that I love. We recently moved and I have a little patio area. So I wanted to build a waterfall. It's 10 feet high and I didn't realize it would be such a futile task trying to find a water pump that will pump that high. So I decided to make one. I attached some images showing the centrifugal pump made from two plastic containers, a water bottle, plastic coat hanger, and construction adhesive that is driven by a drill. It works really well. It gets up to the twelve feet I currently have the hose running up to. But in order to do this, the drill has to be almost full speed which is obnoxiously loud.  I'm looking for some ideas on either how to silence the drill motor, or go a different route. I have to rebuild the shaft as I snapped the plastic rod (hanger) I was using, so I'm open to some rebuild ideas. Thanks so much for the input! I'll post a tutorial once I get a fully functional, stable, and practical prototype.

Machine Gun Concepts

This is for posting pictures of Non-Chain-Fed machine guns that anyone has thought of, and to discuss the designs. So far Oodalumps' is the only one who has created a Non-Chain-Fed machine gun, which is good, but the ammo is fired vertically, reducing range and power. The other type of Non-Chain-Fed machine gun is the Gatling gun, but it has a low magazine capacity. Perfect Duck's machine gun was almost perfect (could you post some pics if you rebuild it?), except that it was bulky. Below is a picture of a gun I am working on.

Old NDS Lite Speakers: Reusable?

I've got an old DS here. The connector for the ribbon cable got damaged, so it's mostly just spare parts in case something goes wrong with my new one. Anywho, I was sorting through what's here, and I can't help but wonder about these little speakers. They aren't fried or anything. Could they possibly be salvaged and used in a project? If so, what? I dunno. A project that makes use out of salvaged NDS parts that doesn't necessarily involve just rebuilding a broken DS would be interesting. Any thoughts?

disability challenge: rebuild my legs.

Just thought it was worth asking with the wealth of expertise and knowledge on here if anyone could offer any help/idea, or any words of wisdom in regards to getting me back on legs and out of my wheelchair, I will gladly consent to being a guinea pig (within reason obviously! lol).   O.K. a little bit of me & my background. I'm a 46 year old male living in the U.K, 12 years ago through no fault of my own I was ploughed down a street by a car. this left me with a compound fracture of my left leg that developed a further complication that resulted in me losing the leg below the knee the resulting infections meant it wouldn't heal . the right leg suffered 14 breaks between the knee and ankle, the ankle was broken and most of the foot. the metalwork in the leg had problems it eventually bent. i put every penny into an operation to remove a large chunk of my lateral muscle to be transplanted to the left stump to get it to heal and to have the faulty metal top of the metalwork replaced, but and I kid you not, the bolt in the right leg had the head taken off!! meaning the bolt would have to be drilled out but that would shatter the leg meaning i'd lose that leg too, the op on the stump was a failure. so what i'm hoping is some of you super brains could help design/devise a kind of prosthesis and a caliper type erm... thing, for the other leg. well I'll upload some pics and a bit more about me tomorrow. thanks for reading guys & girls.

M14 Barrel Fix

For anyone that has or is thinking of building my M14. For those that have built it, you probably may have notice that the barrel at the end does go off at a bit of angle. Luckily I happen to rebuilding it again today and that problem has been fixed. As shown in the pictures, you simply take out the green rods on both sides and then push the orange connectors forward, add a rubber band and the problem is solved. I will include this pictures in the instructions Thanks to those that left a birthday comment in my 21st birthday forum topic, really appreciate it.

I spliced them together and while doing so, I thought to myself "self, how could i run it once i'm done? My question is, the rockbox program for ipod puts its programs on ipod nanos to play video, why not use this hole in the ipods security and replace the rockbox files with a webcam program to make the webcam attached connector functional?

Turn a Monitor into a Drawing Tablet and mount it in desk

I'm rebuilding my entire basement office this summer and I've had an idea for a really cool tablet substitute.  I'd love to be able to mount a monitor in my desk and get an overlay for it to allow for me to use a tablet pen on it.  I have a vague idea of how I want to do it, but I'm hoping that you guys can help me come up with a sturdy way of mounting it in the desk and where I can get an overlay that isn't touch sensitive (this is going to have my hands on it when I'm typing, then when I need the tablet function, I'll move my keyboard over), but responds to a pen. Thanks for helping!

Looking for Info On These CNC Motors For Replacement

I purchased a surplus 2-axis CNC machine with built by Yamaha. I hoped to rebuild it into a new machine for myself, but it ended up requiring 200 volts AC for the controller and motors, which I don't have access to. I sold off the controller already. I don't know too much about professional CNC macahines, hoping someone has some input. I am hoping to replace the motors with ones in the same form-factor that run on DC or 120v AC(if such thing exists), preferably stepper type. I do not know what form-factor/package/mounting style to look for, or even if any are available with the power requirements I want.  Motors are the same for both axis and are part#: TS2620N664E122, attached are some pictures.

K'NEX Magpul Masada ACR V.3

Hey guys! One of my favorite Instructables of all time would have to be my previous Magpul Masada ACR. I really just loved how it looked, how if felt, etc. So, after all this time (and after not a few request) I decided to rebuild it, and give it all the experience I now have (that I did not have back in January of 2013). This version (now version 3) has a bunch of new stuff, such as: - New stock (adapted from my gun Reliable) - New (better) mechanism - New flip-up sights - New lower receiver (adapted from my AAC Honey Badger)  Overall, it is a great improvement, and I can't wait to finish and post it. Tell me what you guys think! Enjoy! -The Red Book of Westmarch

When creating an instructable, Publish tab does not work.

Hi, I've been on Instructables for over 3 years and thought I'd create my first instructable today, through the video instructable template.  I have managed to create a draft fine, exactly as I wanted it. But when I click the Publish Tab, the little updating bar comes up for about 1 second, then goes away, and that's it, it's still on the EDIT tab, and has not been published or changed anything. I've tried it in current versions of Firefox and Chrome, but it's the same in both browsers. Everything in the EDIT and SHARE tabs work fine, it is just a problem with the PUBLISH tab. My OS is Windows 7. It is really puzzling to me as to what is happening and any help would be very much appreciated. The Instructable's name is: "How to diagnose & rebuild an electric vehicle winch Part 1 (Warn XD9000)" . Regards, JD

Slinghammer Bullpup Edition

Because I had some time on my hands last Saturday, I decided to revisit my Slinghammer (A.K.A. the R1), but instead of just rebuilding the old gun, I decided to make it "bullpup operated." This version, the Slinghammer BE (Bullpup Edition) is more powerful, arguably more accurate, gets better range, and is less piece consuming that the first and second version. But, all of these advantages come at a cost. The Slinghammer BE does not have a adjustable stock, it is not as cool looking as the second Slinghammer version, and it is not as easy to load as the first version. Features: - Looks O.K. (IMO) - Accurate up to 80 - 90 ft. - Great ranges: 100 - 120 ft. - Modeled after the SRv3 - Very comfortable handle - Really comfortable stock There you have it. I thought that I would just let you guys know what I am working, what I'm keeping busy with, etc. Also, BE SURE TO CHECK OUT THE NEW POLLS ON MY SITE. Find them here. -The Red Book of Wesmartch

Glass Desk

So I'm in the middle of this rebuild of this stand up desk that I am finally getting around to. Now I tore off the old laminate, it was cracked so on, and so on. Now I was going to just put new laminate on it however, I sanded down the wood directly below and while I was rearranging my shop I  placed some glass I had laying around on top of it. Looking at it I realized I wanted to put glass on it instead of laminate.... (Thought process incase anyone is interested.... No one? Okay moving on.) Two questions.  One What type of glass should I use for the desk. I know tempered glass is safer, however I also know it will break much easier. Plus, the glass wont be floating with nothing below it so its not like if it does break glass will go everywhere if I use normal glass. And I don't want to use plexiglass because I don't want to have to deal with scratches.   Two Can I go to Home Depot and get glass cut to my dimensions needed for the desk?

How can I use my old laptop monitor as a screen for my computer (in car) ???

I'm rebuilding and upgrading my old laptop into a 'carputer', I removed the screen as a whole unit, however, i'm fairly adept with car mods and I believe I could adapt the centre console to take the 14" screen as opposed to a costly new 7 or 8" alternative. Electrickery is, alas, a weakness of mine, theres a very short lead coming from the screen, how would I extend it or change to a dvi or vga or summat??? Also the enclosure (standard screen off laptop) is quite bulky, what can I damage by taking the screen housing apart, whats in there... *carries on asking questions in a similar vein, getting more garbled and confused by the second*.....Any help would be greatly appreciated, as there are squirrels holding me hostage and they have guns and...BANG...."squeak, we told you not to say anything, squeak"........."Ah, nuts. I shot the hostage. (nuts, geddit?! sorry :-l)"......

How to Break Solder Tabs On Ni-Cad Battery Pack

So, in a fit of optimism I decided to rebuild a Ryobi One 18v battery pack for my drill. The task seems rather straight forward except that I can't gracefully remove the soldered tabs on top of the batteries that actually make the circuit and connect to the wires.  In the past, I would have removed something like these tabs by either holding the soldering iron to them to melt the solder, slicing the solder with a razor or a combination of the two. These tabs, however, are seriously attached. They won't pry or slice off and the metal of the tab begins to melt before the solder does if I try the iron. I think anymore heat will damage the battery themselves.  Now, it's been a while since I did any electronics work but after a couple of tries I remembered which end of the soldering iron to pickup. I don't think I missed anything. It just seems like these tabs aren't attached with run of the mill solder.  Has anyone had this problem (and found a solution) or am I just missing something blindingly obvious?

Rebuilding after the end has come to pass...

The year is 2054, the human race has endured its biggest and longest war ever leaving the last survivors to fend for them selfs in its wake. To make matters worse, a human designed diseasse has spread, thinning out the last survivors to less than 50.000 people all over the world who happen to be lucky enough to be ressistent to the dissease. There are no more governments, no more borders, no forms of modern society ''at all...'' except for your own rules and moral state of mind. Raw modern resources are almost all used up, maybe a few drops of oil here and there but not enough to be reliable for longterm use at all. City's have burn down to the ground, blasted into the sky or have bin left to decay and rust, there are simply not enough people arround to keep them running. U, yes U are one of the lucky ones to wake up one morning, having your loved ones by your side and you can see the sun come up! Your in a forrest, your car has run dry on fuel, but your alive and kicking! What would you do to survive, build a longterm home and grow out to become a safe haven for "all" who will find your place of refugee? These are the conditions you have that work for you: 1. You are not alone, you have the ones that are closest to you with you all the way. ( ideal situation huh? ) 2. The forrest you are in is huge, deu to the fact humankind has declined in such small numbers, nature hase taken back a lot of groundspace and it is booming! ( again, ideal! ) 3. You have a car, it is broken down, has no more fuel except some fumes, but you have it non the less... ( not so ideal, but still... ) 4. In the trunk you have a tiny solar panel, strong enough to fill your cars battery ( yup, one battery... but its 2054 so the poweroutput is more than enough to help you out in the first stages of building your new home. ) 5. In that same trunk you have sleeping gear for camping, a couple of pots and pans, some basic workingtools and a bundle of paracord, couple of hundred feet in length. ( you like paracord, o yes you dooo... ) 6. You see a chicken in the corner of your eye... your running condition happens to be excellent and so you take a sprint... There's your protein... ( eat the chicken, or keep it for later use? its yours now, so do what you want with it. ) This is whats working against you: 1. Guns are not a good option. All rounds off ammo that where ever made have bin used up. Even your trusty ol .45 lays in the back of your trunk not knowing its own purpose in life anymore... ( so sad... ) 2. City's? gone! Piles of rust and decay are the only things that are waiting for you over there. ( pluss, the bandits roaming the city are not the most happy bunch to cross with. ) 3. Fuel, nope, fumes, yes... ( not much going there... ) 4. Communication devices are out... ( you forgot to pack your radio, and now you have nothing to reach out with... or do you? ) 5. The spot your in is most beautifful, really, its the most beautifull patch of forrest you and all around you have ever seen!!! The gigantic mutated bears and stray wolfs think so too... ( Radition and the human designed diseasse worked toghether in the animal kingdom making these guys grow almost double there original size... see statement 1 for double sadness!!! ) Ok, taking the mutated bears and wolves aside, think outside the box. You have a car, thats something, and these bears and wolves will leave you allone as long as you let them do there thing. And if they dont get hungry enough to eat you ofcourse. ( Its a mutual agreement i guess. ) Im curious to see what you guys come up with, so be my guest and spit it out ;-)

Recycling old funfair "light" guns

Hi, first of all, I'm not sure I'm posting in the right place, if I'm not I apologize, but I couldn't find any that seemed more correct. Anyway, my grandfather passed away many years ago and among his knickknack were two handguns and two rifles that he had crafted for a funfair he worked at. (Images at the bottom) All 4 are originally made shoot light as far as I'm aware (he passed away when I was very young, and I've never seen them in action), they look like they are meant for light at least, as they all have lenses inside the barrel. That said they don't look functional anymore, and especially not the rifles as my little brother wanted to rebuild them for laser tag, but only got as far as taking them apart. The thing is I have some experience with electronics (Arduino, Raspberry PI and more) and a few years of experience programming (though mainly pc programs). I want to make something with them, but I've had them kicking around for a while now, but to be honest, I have no idea what I could do with them. Any and all ideas are appreciated =) (except suggestions about turning them into real weapons ;) ) Regards -Logan

Tour of the Largest Private Collection of Military Vehicles

Through the MIT Club of Northern California, Christy and I got the chance to tour the Military Vehicle Technology Foundation's collection in Portola Valley. Seeing 100 tanks from different time periods lined up and seemingly ready to roll was pretty amazing. I've always had a thing for half-track vehicles, and was especially pleased to see a half-track motorcycle (SdKfz 2 Kleines Kettenkrad). In all honesty, this is probably one of the most impractical vehicles ever created, but it just looks so cool. My other favorites to see in-person were a SCUD missile launcher (SS-1b Scud A) and an M48A5 AVLB (armored vehicle-launched bridge).They also have a large shop where they repair, rebuild, and often re-engineer parts to restore the various tanks. While I was there, they were in the middle of repairing a World War II-era German tank found in a river. The collection is the hobby of Jacques Littlefield, whose father, Edmund Littlefield, amassed a $1.7 billion fortune by running the family construction and mining company, Utah International, and merging it with GE (more here at Forbes).The Instructables forums aren't exactly the best place to few 57 pictures, so here's my Flickr set, and here's the Flickr set of the person who organized the tour.

Tool-use observed in molluscs!

Everybody knows that humans are "special", somehow different from the other animals on our little blue planet, but it is very difficult to define just how. An early casualty in defining "special" was tool-use.  First chimpanzees, then primates, even birds were observed using tools - hammers, anvils, probing tools, fishing rods, weapons. Now a mollusc is being presented as a tool-user. The veined octopus Amphioctopus marginatus has been filmed by divers collecting coconut shell halves (actually human litter, dumped in the sea) and carrying them away to use later as a shelter. Their habitat is open, featureless sediment, no protection from predators.  The shells provide vital shelter in the exposed underwater plain. If the octopus finds a single half-shell, it digs it up, carries away and then turns it over when needed. If the clever creature is lucky enough to find two halves, it stacks on inside the other, then later "rebuilds" a whole coconut, except this time with a yummy octopus filling. This is another example of high-level intelligence in these bizarre animals.  To me, octopus are a prime candidate for the next "special" animals on Earth, once those polluting apes are out of the scene...

Latch-less Non-Perm. Seal?

I have a great passion for lighting things up through the use of LEDs. For one project for school, I took about 40 LEDs and surrounded a "billboard" (3 by 2 foot box made of posterboard - actually looks very nice). While this is good and fun, I ran into a problem. This is not the first model I have made. The very first model was for another project, but with no way to change what was on the "faceplate" (the area the LEDS surround), I was forced to rebuild a second model. Well, I am now required to make yet another copy. But I don't want to recreate the entire billboard, for it takes about 16 hours to build. I instantly came up with the idea of "attaching" other faceplates to it. Velcrow made the most sense - you can remove faceplates, or add new ones whenever you wanted. But velcrow is not affordable at the time. None of my local stores have it in stock, and the soonest any store near me will have it is after Christmas. This due date for the assignment is the 21st of December. I essentially just need to be able to, using as little space as possible (the LEDs only peak through so far), create a way to add, and later easily remove, a faceplate. Latches won't work because it needs to have absolutely NOTHING on the front of the faceplate, for content will be spewed all around the board. Ideas?

Revised TR8 review

Ok, so I decided to rebuild it, and I found I got some stuff wrongBodyStock: 8/10 Why: comfyHandle: 8/10 Why: Comfy overall, but there is this spot where I get poked sometimesTrigger: 9/10 Why: seems very reliable, It didnt break this time around (idk why, I built it the exact same way I did from last time), but when you remove the rubberbands, that green rod can fall out.Barrel: 9/10 Why: works very well, but its a generic tube and stickTurret: 10/10 Why: It works awesome with the rest of the gun. Looks: 9/10 Why: looks tight, especially when loaded up with red rods, but the turret seems a bit out of place with the rest of the gunPerformanceRange: 10/10 Why: 90-100 feet flat (2 rubberbands)Power: 10/10 Why: its the most powerful gun I have ever made. It can shoot through various heavy duty cardboard boxes with 2 rubberbandsReliability: 8/10 Why: the turret is a very effective method for the repeater, however, it sometimes skips rounds, but rarely.Innovation: 7/10 Why: nothing that new, except for the revolving mech and the trigger.Recommendation: Yes, I would recommend it to anyone who doesnt want to use a bulky knexsayer, or a single shot in a knex war.Final rating: 9/10

Instructables in the New York Times -- Romancing the Flat Pack: Ikea, Repurposed

Instructables, member mzed, and his Low-cost Spherical Speaker Array all were mentioned in Romancing the Flat Pack: Ikea, Repurposed by Penelope Green at the New York Times. ..."I think there is a movement around looking at all the products that are available -- this global stream of stuff -- and realizing you can tinker with them and rebuild them," said Michael F. Zbyszynski, 36, the assistant director of music composition and pedagogy at the Center for New Music and Audio Technologies at the University of California, Berkeley, whose own hack is a speaker array made from red plastic Ikea salad bowls, and who has made other musical objects from PVC plastic and coffee cans that "live in the zone of the hack," he said."It's all about not accepting what's presented for sale as it is," Mr. Zbyszynski said, "about not just doing a 'paint by numbers' of your life."...ReadyMade is part of a universe of D.I.Y. media and forums where Ikea hacks appear and are then found by Ms. Yap, who links her blog to them. It's a universe that includes Make magazine (more science than design-geeky, for the handmade-robot set) and Web sites like, which was created by M.I.T. Media Lab alumni as a forum for its users to share knowledge about how to make or do practically anything, including, as a glance at the home page the other day revealed, a quick banana nut bread and "hacking a toilet for free water." Mr. Zbyszynski's speaker array, with its goofy "Lost in Space" aesthetic, first appeared there.See more news mentions of Instructables here.

3D Precise position/orientation tracking for body-worn camera

Hi all, It's not a new question but the available technology keeps changing so I'll ask this again, having not found any current answers online that are useable at a diy, non electrical engineering level... I'm working on a project in which a body worn camera is tracked in space, then recreated as a virtual camera in the corresponding virtual 3d space (kind of like a lo-fi version of the cameras used on the "Avatar" set). This is to be done over 15-60 minute durations in an indoors area of about 30X30 feet. What I need for this is tracking of the camera's position and orientation in space, precise and continuous (as much as I can get, but at least within and inch or 2, and a few degrees, of the true values),  to be either logged on the tracking device and/or transmitted to a computer on set. Since it is body worn, it needs to be light and wireless. Since it's on a moving body in a space with some objects in it, optical tracking isn't really a good option. I looked at a wide range of solutions, from "flock of birds" and the inertiaCube on the crazy-expensive side to sparkfun's IMU sensors, but frankly am a bit bewildered by the selection and don't know how to figure out which is the best to try first, given my needs. I'm really not looking to reinvent the wheel or rebuild everything from scratch, just find a solution for this not costing more than a few hundred dollars that is fairly reliable. Software-wise I want to be able to get 3D XYZ position and rotation values from it that I'll be able to use in Realtime 3D software such as Max/MSP Jitter and the like. Any ideas, stories of previous experience with such setups, links, etc would be extremely welcome. Many thanks! nadav

Up and Coming

Contrary to popular belief, I havent left instructables, and I havent died. I have however been working on bunches of projects (some of which you may remember from my "Things I'm Going to Post Soon" slideshow). Unfortunately, most projects, such as a crossbow, slide-action pistol, semi-auto sniper, etc., have miserably failed. And even worse, several projects (FAMAS, M6G, and the D.R.A.G.O.N) have been demolished for lack of pieces, and will need to be rebuilt. The first project to be posted will be my M6G Magnum (halo 1 pistol), which should be up by the end of the week, followed by my completely new Sniper, the KSR (at least until I find a better name), which I have made since, according to previous feedback, my R700 simply wasnt cutting the jib. It features an extremely comfortable handle, an upgraded trigger system, and better overall statistics (range and accuracy). After that is posted, I might be able to rebuild the FAMAS, or the DRAGON, but dont get your hopes up, they are hard to remake, so I'll probably just make a new gun, such as the Shipka SMG. Stats: M6G Magnum •Range: ~ 20-30 ft. •Accuracy: Consistent •Mag: Loads 9 pcs. KSR •Range: ~65-70 ft. (depending on bands) •Accuracy: Very Consistent •Mag: Single shot / rail system FAMAS •Range: ~30-40 ft. •Accuracy: Good consistency •Mag: Loads 12 pcs. D.R.A.G.O.N •Range: ~50-80 ft. (depending on ammo type) •Accuracy: Medium consistency •Mag: Single shot / dual rail system PS - Constructive critisism is welcome, but dont just say: "wow _____ gun sucks" The pictures are as follows: 1. M6G Magnum (w/ comparison) 2. KSR 3. FAMAS (w/ comparison) 4. D.R.A.G.O.N

OK that's it. What do you want me to build?

I'm getting a knex bucket from my friend cheap tomarrow (or maybe today if the forum shows up late like always...) and so I'll have enough pieces to fufil most requests. I still have my "will replicate any gun" thread going so check that out if you want me to make a certain gun. I just really need to build something. I'm also itching for making some new innovative design so I need ideas. Tell me exactly what kind of gun you want (shotgun, sniper, sidearm?) and I'll see what I can do. I also want to get more videos up on youtube. (masterofthelines -check me out later on this summer to see what I'm up to. Hey maybe you'll eventually meet who I am under "TheDunkis") So yeah tell me any details but for the love of god IF IT INCLUDES ANYTHING ABOUT FULL AUTO I'M JUST GOING TO FLAT OUT IGNORE YOUR POST AND POSIBLY YOU FOR THE REST OF MY TOPIC. OK just had to get that out of the way. And I doubt I'll think of any new semi auto ideas but feel free to mention any other ideas you think might be possible. Oh yeah tell me does anyone right now feel interested in another M4 that both looks good and has a good working magazine and rail system? I made one before but ran out of pieces so I might rebuild it again. I found out most guns here can either look good and not be the best or they can work awesomely...and not look the best. I know most of my guns aren't the greatest quality and that's why I'm trying to improve and at least mine worked for the most part. ~TheDunkis~

Recumbent cycle: "blue sky" design query

I am not one of nature's cyclists. I didn't actually learn properly until I was in my twenties. My bike is very old, very rusty and very, very heavy.However, I feel that I "ought" to cycle more, for shopping trips and the like. I quite like the idea of switching to a recumbent, but they are expensive (current available funds: zero).So, I'm playing with the idea of rebuilding my mountain bike into a recumbent (and learning how to weld on the fly?).In the sketch below;The black section is the back of the old bike, turned upside down.The blue section is the front of the donor bike.The red part would need fabricating somehow.I haven't thought properly about steering mechanisms, but probably under the seat, via cables to arms welded to the forks of the will-be-the-back wheel.Would the bike, as I have sketched it, in principle, work?I'm bothered about stability, especially at take-off and landing. Am I worrying unnecessarily? I have access to a second donor cycle. Is there any mileage thinking about "doubling up" the blue section, to make a trike? Not massively wide, but I could add luggage space, or an extra rear-facing chair-style seat.Brakes: before I cut up the bikes, am I right in thinking that I just remove the cables and levers from the handle-bars and add them to the under-seat steering?Gears: the donor bike is a mountain bike, but I never used all the gears anyway. This area is pretty flat - can I get away without any gears?Coasting: although the back of the donor bike ends up upside-down, it is still turning the same way, so I can still coast OK.I'm sure I've missed something obvious...Anyway, even though I've not decided to do this for certain, I'd appreciate any comments or thoughts.

Multi Part Instructable?

I am making an instructable for building a gas powered bicycle from scratch, but in it's current form, it is shaping up to have literally hundreds of steps. Is there a way to break it down into smaller sections in such a way that I could still enter it in a contest as one instructable? I was thinking perhaps I make an instructable that consists of only the introduction, followed by quick overviews of each part, with accompanying links to other instructables which are dedicated to each part. The way I am planning to do it, I would have one instructable for how to modify the engine, another one for choosing a good bicycle to motorize, another for mounting the engine to the bike frame, another for calculating gear ratios and setting up gear reduction, another for rebuilding the rear wheel, another for throttle linkage, another for exhaust systems, gas tanks, and air filters, another for all the other misc stuff you have to do, and finally one more for how to ride safely. So that would be 9 parts to the instructable, each their own instructable, which even split into 8 would make quite large instructables. Then the "parent" instructable, which would be the one I enter in contests, or which would be featured if it's worthy, would look like this: How to build a 4hp motorized bicycle from scratch! Blah blah blah introduction, nice pictures of finished bicycles, etc. Step 1 short overview of specific part, ex modifying the engine, then link to another instructable providing detailed instructions on exactly how to modify the engine Step 2 same format as step 1 and so on until all the parts are covered. This would also be helpful to me because I could better organize the hundreds of images I have for this instructable, right now it is a huge pain in the butt to find any specific image, so much so that it's easier to upload them one by one as I need them just so I can keep track. So, would this format be ok?

R5, Bolt Action Carbine

Hey guys! After the "rebuff" I received from ZakS and FlyingFish10 (and more kind comments from TheDunkis and Raz1r Knex Bull3t) about how my K'NEX Gun: Declaration (R2) looked just like a ZKAR (to which I disagreed), I decided to rebuild and heavily edit my K'NEX gun Declaration (R2), changing the body and mechanisms so heavily that the comparison between it and the ZKAR would be virtually non-existent. After about three days of hard work, I have finally come up with this gun, the R5. With a brand new trigger mechanism and bullet transfer system, this gun is ENTIRELY different from any other bolt action gun you will find. While the bolt itself is heavily similar to the ZKAR / Zaktangle, almost everything else is entirely unrecognizable (except the magazine, that's a pretty standard yellow rod magazine). Features: Brand new trigger mechanism Brand new bullet transfer system Heavily edited (and improved) pin guide setup Comfortable stock Very reliable New magazine setup, with magazine breach Comfortable grip Flip-up back sight Great range: 50 - 70 ft. Preloadable magazine Internal magazine pusher 12 rd. magazine (could be increased) This version is by no means finished, but when I do finish it, I'll be sure to post a full set of instructions. Check out the image notes for more info. Tell me what you guys think I should change or add to this gun. I'd love to hear your comments. Quick Tip: When you have a magazine that is full of rounds try and make the last round different in some way, so that when you shoot the gun you know when the magazine is empty. This will prevent you from shooting the magazine pusher, and make it so that you don't have to keep track of how many rounds you've shot. -The Red Book of Westmarch
