I have dust clinging to my popcorn ceiling near the heat ducts and would like a fairly easy way to remove them...thank you jpp
As I understand electromagnets, you wrap a wire coil around an iron rod and run current through the coil. As long as there's current going through the coil, you have a magnet... But when you cut the current, no more magnetism... I want to create a circuit in which a hand crank charges up one or more batteries or capacitors, which in turn discharge slowly through an electromagnetic coil (such that the magnetic field of the electromagnet gradually diminishes) over the course of an hour or so. The overall idea is that you crank the crank for a short while, creating a magnetic field so that BBs cling to the electromagnet. But little by little, over the course of maybe 20 or 30 minutes (longer would be OK), the BBs drop off one by one (or a few at a time). Can anyone suggest what such a circuit might look like? What variables will determine how long the crank has to be turned, how strong the magnetic field will be and how slowly it will discharge? And will the BBs only cling to the ends of the electromagnet? Or will they cling along the length of it as well?

Please, it's urgent. I've broken a metal cross-head screw, there is nothing for the screwdriver to cling to. I cannot preform the hammer method due to the object the screw is stuck in being plastic, and I can't afford to break the plastic. Please, I need you to help me. Dylan P.S This is a nerf gun (the hornet) and the screw is near the cocking mechanism.

I want to be able to use varied fonts so I dont want to use stencil technique. I don't think its air brushing I want either, I am not sure. I want to take a piece of luan wood and paint it and then add lettering to it. Like the vinyl cling-ons you can purchase for walls in your house.

We keep a kind of chilly house in winter . Sweaters and sweatshirts are expected, except for company. In our area, we heat and cook with natural gas and that is cheaper than electricity. But the cheapest heat is residual from cooking . So a kettle is always on for tea whenever wished. And most nights we bake potatoes unless the daughter bakes brownies or something. And, in addition to that we will stick bricks in the oven. Come bedtime, the bricks get wrapped up in towels and put in the bed. where toes can cling to the brick and other toes. Best strategy for bricks is to bake them at 175 for a couple of hours. Please spare the obvious comments, but please make other homey suggestions.

I need to figure out what to use for a certain application. It needs to have small particles, say the size of large glitter flakes, sand, styrofoam balls, or those tiny glass beads without holes that people glue onto ornaments. I'd prefer if it could pile up a bit like damp sand... not too high, 1/2 inch max is all I need. I need it to not rot or deteriorate in a closed container for an extended period of time, and I need it to not attract a charge over time and cling to the sides of the container (like glitter and styrofoam balls do). I need to be able to push it around easily if, for example, I dragged my finger through a pan of it. I need it to be white or clear.

My son's friend 'dropped' his phone. Being quoted upwards of £50 to fix. My husband is wondering whether an epoxy could be used to fill in the cracks - as all is working. It's just the shards on front of screen are at present dangerous - I can testify to that as we took off the cling film we had initially covered it in at the repair shop - put it back in my handbag - and I then ended up with small slivers of glass embedded in my thumb. Nice. It's just such a shame. Was an old contract phone, given as a present to my son - and everything works !! Epoxy seems so easy - but will it ruin the phone?

For a while I've asked that when "the cats" die I can have them to turn into Davy Crockett Hats, with the tail hanging down at the back. This is because: -They have nice tortoise-shell fur -What else do you do with a dead-cat -How many Davy Crockett Hats have you actually seen? When I was discussing this today, I was asked about the cat's head... which gave me the idea of having the head and paws on with an mp3 player and speakers in the front-paws. So you'd have an Mp3 Cat Hat, that looked like you'd got a cat clinging to your head, with it's front paws in your ears. It's a bit mad, but I think someone would buy one. Maybe mouse-mouse-minded people might make one? Or it's a knitting/crochet project. L

Hey there Brochachos, Ok, having just dug in on my first project, I'm more than overwhelmed by the sheer volume of 'stuffs' I need to learn to accomplish my goal. Howevever, having done a substantial amount of reading, I believe I've got a fairly focused question that can hopefully pull a concise answer out of the beautiful woodwork of this community. Onward... I'm trying to interface a gantry style xy table that uses some softpots as positions sensors for the x and y axes. I want to send this analog signal wirelessly to two servo motors that will respond to this analog signal accurately, with minimal latency, and no jitter. As a fairly new egg in the DIY self world, I stubbornly cling to Arduino for comfort and the xbee modules seemed like a good fit, but the workaround to transmit an analog signal seemed troublesome and the servos always seem to develop a Parkinson's syndrome of sorts. (at least with the builds I saw). The question... What transmitter/receiver is both extremely amateur friendly, with regards to setup, and can also get the signal (sans Internet connection) at least 100ft to the receiver where it gracefully manifests itself on the servos as smooth motion. If you don't have a definite answer, pointing me in the right direction of relevant reading is also greatly appreciated. If there is anything I've left out, just ask. Thanks in advance, I love you, but not like that... -Z

Whenever I touch my Xbox 360 after playing it for a while, it shocks me. It's really fucking annoying. It hurts too. It's made my finger go numb at the tip a couple times. I put a piece of a static cling fridge calender over the drive eject button, and that works most of the time, but any time my finger is a little bit off the piece of plastic and touches the Xbox, it shocks me. It gets me if I touch a thumb drive I've had in there a while too. I think it might have something to do with me not being grounded to the console via a controller wire, because my controllers are wireless, unlike my GameCube ones, which I would never (or rarely maybe, I dunno) get shocked from. I have another problem too, I have this mouse pad with a wrist rest, but the mouse pad part of it is fabric on top, and always catches hairs and dirt and stuff, so I cut it off. I have the wrist rest taped to my keyboard tray now where it would normally be, but I'm using a Dell mouse pad that came with my computer. The problem is, ever since I've started using it (yesterday) my cursor has been twitching, anywhere from a few centimeters to going all the way to the edge of the screen. This happens constantly, probably once a minute. This is also driving me crazy. I've heard that having a mouse pad with colours and stuff like that all over it can make optical mice twitch. The one I'm using now is just different shades of grey, I don't think it should be this bad.

In May 2006 something incredible happened in London. For four days the city stopped in its tracks and marvelled at the sight of a gigantic wooden elephant, and a little-girl giant in a green dress. Hundreds of thousands of people jammed the streets, astonished at the scale and beauty of the spectacular Sultan's Elephant.Now Artichoke, the company that brought that event to London, is working with the engineering genius behind Royal de Luxe's giants, FranÃÂ§ois DelaroziÃÂ¨re, and his company La Machine, to create a magical and astonishing new show especially for Liverpool, European Capital of Culture 2008. Liverpool08Something unforgettable is happening in Liverpool as a highlight of the cityÃ¢â¬â¢s European Capital of Culture celebrations. Vast in scale and spectacular in execution, this breathtaking new commission from La Machine will spin a tale so magical that an entire city will fall under its spell. Just as The SultanÃ¢â¬â¢s Elephant stopped London in its tracks in 2006, so this three-day adventure will unfold against the landmarks of a great city, stopping the traffic and captivating everyone who sees it.

Alright sorry I know DGM already made a thread for me but I'm going to make my own so that I may update it with the most recent additions. We're are still very much alive and not closing down after all.http://knexables.uuuq.com/forum/index.phpAlright so I made a site called K'nexables (uncreative I know I just wanted a quick name) because I didn't like everyone clinging to 'ibles. I know that the insults have gone down but we'll never be highly respected in the community. And it would still be nice to have a place of our own. However, KI isn't a favorite for some of you. I can't blame you but I know there are those of you who like it so I'm not targeting you. I'm not trying to compete with KI I'm simply giving those who don't like it the option to join me. You may be wondering- What does TheDunkis's site have that would make me want to use that instead? Well here are some current features and some soon to come.-Chat with different categories based on the forum. If you're a member of the forum you're a member of the chat.-Wide selection of categories including non K'nex topics.-Good amount of BBcodes to make posting easier.-VIP forum. Equivalent of the Secret forum on KI but there are many more ways to get into it.-Constant Contest. We may have more than one running at a time (although all ending at different times so that you may participate in all of them even if low on pieces). Sorry our prizes aren't physical but you can still earn a variety of forum prizes.-Friendly atmosphere. We'll attempt to be a little more friendly than KI. Not saying that KI isn't but they can be intimidating to new members. I'll have some firm but strict rules with a fair and just punishment system.-Not that most of you even care but me and couple others are planning on prioritizing KA as our main posting site. All of my future projects will be posted here and you'll have to join in order to see them. I'll post them here too though just not for like a month after posted on KA.Alright I think that's all of them so far. Here's a list of the things I'm planning on adding.-Ranks with K'nex pieces for images-Karma or forum rep-Possibly a cash mod for an online forum economy (trust me it'll be used in a variety of ways)-Possibly a portal mod. A sort of front page that has many useful tools.-Anything you want! We'll pretty much add anything that seems helpful and easy if you suggest it. We'll pretty always add a new category if you suggest it as long as it makes sense.Any questions?

Hey, peoples. I'm rather sad to see the community dying but I figured I'll cling on a little longer, try to spark some more activity if possible. I see people still posting instructions, so that's good. Just wish we'd keep more discussion going on the forums. Anyway, a couple things: Just to show what I have around, I tried to make something after my Barackuda but didn't end up going anywhere. I just wanted to have something around, so I remade and improved my SMRI model. This version was designed solely for looks based off my last version. I couldn't really be bothered to try making this one shoot. It still uses Red's stock because I couldn't think of a better design at the time. Anywho, this wasn't meant to be the impressive bit, just something to show while yabbering. =P With the Barackuda and the SMRI, I realized that I'm still limited in a few pieces. I desperately need more dark greys, oranges, and black hands. I also realized I feel bad destroying guns and never keeping them around so that I can build new ones. I figure I might as well build my collection up so I can keep more guns around. So I've ordered more pieces. I'll get them probably some time early next week. I'm hoping to build something right away. I'm thinking of revisiting my Barackuda to see if I can improve the trigger and feed ramp. I might redesign it entirely. I'm hoping to attempt a repeating slingshot of some form at some point too. But it's an area I've never worked in before so I might get discouraged pretty quick. I dunno, I need to try actually building these ideas I have sitting in my head for years. I'll post more in here once I get the pieces and start building something. Update 2/19/16: I'm mostly finished with my new version of the Barackuda. I filled in the empty gaps on the rods of the magazine to make it fuller looking. The trigger -should- work better now but I just noticed it struggles to set when it's still pulled back while cocking. I suspect I just need a better band setup to resolve this, otherwise it works fine when you manually push the trigger forward. Last, the stock was changed entirely to give the bolt a rail to glide inside of with a solid bolt stop right after the trigger engages, allowing for a quick and smooth action. The handle connection is also more sturdy, so the stock is surprisingly rigid. Overall I'm much more pleased with this version, as long as I can figure out the trigger bands this might be posted. I'll begin working on yet another remake of the UMP soon. Update 11/9/16: Man, the year sure flew by. I apologize for never really getting around to posting the Barackuda before. This time I think I've finally gotten over my perfectionism. I've adjusted the stock to keep the same track design but attached it differently and otherwise made the rest of the stock use less pieces. I've figured out a (I think) new pair of K'nex sights more precise than our usual chunky ones, not that it'll help much. The trigger and back of the gun has been adjusted to block the pin further back, hopefully improving range slightly. The front of the gun was made more compact and flat at the bottom to allow potential changes to the front of the magazine in the future. It also makes muzzle loading much easier in tandem with the new ramp. The ramp is also simpler, more consistent, and hopefully offers better range than my other ones. Finally, the magazine has been adjusted to be easier to load and hopefully more reliable. I'd finally say this is a practical war weapon alternative. I'll post this...hopefully sooner rather than later. This time I mean it.
