I've noticed lots of people haven't been targeting hyperlinks ever since the new editor appeared. I think this is becaue it's not intuitive, so here's a quick how to: If you just click the world icon with the chain and paste in your URL you get this. www.instructables.com/you/ So to target your URL, type a name, highlight that with your mouse, then click the world icon and paste your URL will be linked to your target word. for example I type ME Highlight it with my mouse and click the world icon and paste.

Besides the name this has nothing to do with music. most people on instructables has well found out that there are two main groups of people on insructables( but there are a lot of people that like other things!). knex lovers and LED lovers(or electronic lovers). well i am a big fan of both and i found a way to combine them into one insructable. its a knex terget that light up using LEDs when you shoot it! i will post pics of it but i am having a hard time geting a good pic of it( you can only see the LEDS in a pic when it is dark and you can only see the knex when it is light.

Houston, we have bug zappers! No really, just this time with lasers! I was surfing through Hack-a-Day, and I came across this. These devices identify a mosquito by the frequency of its beating wings. Once identified, the device aims a laser and destroys the little blood sucker. That seems simple enough, so: Do you think that this could be accomplished by a DIY for under $100? think about, we may have a really useful Instructable on our hands.

The target window for opening the PDF window is called "_new". This isn't right - it should be "_blank" to open in a new window. Using "_new" means that all PDFs opened open up in a browser tab/window called "_new" and so they all open up in the same window and overwrite each other if you open up more than one at the same time. Available target names are described here: http://www.w3schools.com/tags/att_a_target.asp Should be a quick fix!

I'm looking for a laser that is button activated and a sensor that reacts to the laser. Basicly I want to put the laser in the barrel of a broken bb gun and make the button so that when you pull the trigger the laser goes off. Then I want to make a circle with the sensor in the center and when you hit it with the laser you hear a sound. Now I am wondering where I can get a laser and a sensor that responds to it. the laser can be visible or invisible I don't really care. Also does the sensor respond to any laserbeam or is this specific? Thanks in advance, Michel

I would like to modify a 1:35 scale model tank (it's about 6-7 inches long) so that the barrel projects a dot on the wall and I can determine whether or not 'firing' the tank hits a target.A low-power laser would obviously project the dot, but there are two big problems: the risk of it getting pointed at someone's eye, and the logistics of mounting it in the chassis. Regarding the safety issue, that danger could be lowered by limiting the laser to a 0.1 second burst each time. That's still not safe enough for my tastes, so I don't know whether I'm willing to go that route. And as for the logistics, the turret of the tank will be full of servos, gears, etc., so the laser unit would have to be in the hull of the tank, with the beam channeled to the barrel somehow. Would a length of fiber optics do the trick? Does anyone have other suggestions for channeling the laser?It would be easier from an engineering standpoint to mount an ultra-bright LED in the barrel, but is there any way to focus that into a dot?And finally the target would have to be big enough that there's some chance of actually hitting it - I'm thinking the size of a quarter. I haven't found any laser/visible light receptors that big - any ideas?As an aside, I don't like posting questions without having done some legwork first - I have actually researched this, but haven't found useful info...Thanks!

(http://developer.mbed.org/platforms/) During check, I found that there are many Platform vendor and Target vendor. But Platform vendor (which dose not have own MCU) made platform boards with NXP chip only. I am wondering about why they make Mbed plaform with NXP chip only althought there are many other MCU vendor (target vendor). Is there any master who know about this? Thank you.

This game is called heavy cannon knex war you have a heavy cannon in the center of your yard. an one target a 12 inch cardboard box 4 ft off the ground on each side your side and your opponents side Players can only have a assault rifle the goal is to use the heavy cannon to hit a target on the enemys side but only one person can use the heavy cannon at a time if you get hit while using the cannon a member of your oppentents team can take the cannon and you must return to your side first one to hit the target wins the war. IMPORTANT: THE TARGET CAN ONLY BE HIT BY THE HEAVY CANNON NOT THE ASSAUT RIFLES IMPORTANT: IF YO HAVE THE HEAVY CANNON IT CAN ONLY BE SHOT AT THE TARGET NOT OTHER PEOPLE
Question by superbestknex | last reply
Hi! I would like to create a project for the random selection of shooting targets. E.g. each target should show up and stay there for 5 seconds and if not shot down the servo should pull it back. Does anyone have the code required for random selection of servos and making sure they delay between on and off is 5 secs? Ideally the random component would ensure that all targets have an equal chance of being selected but only one at a time.

In the sport of fencing, like many other sports, speed and reaction are very important to us. There are currently no training devices out there that we use to measure speed and reaction in our sport. There are two devices we'd love to have and use, but none of us are technologically educated to know how to build any of these, and hopefully these are simple enough that someone might offer some solutions. Project/device 1: Reaction Measurement We would like to measure a fencer's reaction to a stimulus. The fencer must hit a fixed target (like a pad) when a stimulus is presented, for example, a light. When the light goes on, the fencer must hit the target with the weapon (more specifically, the point of the weapon) and a timer will tell the fencer how long it took between the time the light came on and when the fencer hit the target. Note: Potential problem: durability of the pad getting hit numerous times. Project/device 2: Speed Measurement More importantly, we would also like to measure the time difference between when the fencer hits the target and when the fencer's front foot leaves the ground in a lunge. Ideal device would be some kind of pressure plate in front of the target, beneath the fencer's front foot. When the fencer lunges to hit the target, a timer will measure the time difference between the fencer's foot leaving the pressure plate and when the target is hit. Please let me know if these devices can be made, is it even easy to create something like this...remember...I'm not tech savy!

I just wanted to check with the community out there to see if anyone knows of a good place to start building a tracking system that is GPS based. essentially, a person or object will wear a gps device and there will be one placed on a camera gimbal. I am hoping to create a way for an arduino to do the math so that the camera stays fixed on the target no matter where the target / camera moves. Any thoughts??

Check out Sock Wars, a knitting-based game of assassination by socks.This sounds awesome, but I definitely don't knit fast enough to even try. (And I've never knitted socks!) Some of you might find it useful, though... looks like anyone can join from any country. Sign-ups close 3 May, assignments go out 9 May.From their info page: WHAT IS SOCK WARS?Sock Wars is the original and bloodiest extreme knitting tournament. If you are brave enough sign up to do battle you will be emailed a top secret assassination dossier on 9th May 2008. This file contains the details of your target and an exclusive, never-been-published-before knitting pattern with which to assassinate them.To kill your target you must knit them the pair of socks in the pattern (your weapon) and mail it to them. Once your target receives your parcel they are dead and must post their death on the "fallen comrades" section of the sockwars site.They must also immediately send you details of their intended target (who becomes your next person to assassinate) along with their unfinished knitting (which becomes your new weapon).All the while this is going on, someone has been assigned you as their target!Prepare to live in fear! Kill or be killed!

I am designing a bucket with a small LED sign on it, and I want the sign to light up when people successfully hit a target in the back of the bucket. Everything has to run on battery power, and the entire product has to be mounted on a pole (which will be held in hand). I have considered motion sensors (Parallax PIR) and some sort of laser trip-wire (as one would find on a garage door system), but I am not sure how to implement either. I have also looked into shock sensors, the kind used on some window and door security devices, however, I am not sure that the objects being thrown would be able to provide the shock needed (think toy cars, beaded necklaces and other small novelty toys). The sign will consist of up to 200 LEDS, and it would be nice to have it stay lit for a second or two before turning off again.

Hey guys! Today, I'm going to be reviewing a 10 shot, auto-loading rifle by Bannana Inventor. Some notes before I start. -All credit goes to the builder, not me. -I'm rating on a 1 to 5 scale. -I review guns by request.(the dragonuv is up next) Ok. Now that you have that. I'll start the review. Handle/Gripping-3.8 The handle could have been a little slimmer. Plus there isn't really a good front grip-type-thing.(Yes. I had no word for that situation.) Range-4.5 Pretty good, especially for its size, and the fact that it is a magazine-fed gun. I got mine about 35 feet. Accuracy-5.0*** One word- Pinpoint. Power-3.0 It's power is restricted, since the bullet is so light. But for the bullet, it has some power. Body/weight balance-5.0*** Great balance throughout the gun. The body isn't flimsy. Stock is comfortable. But on a note, which was stated by The Jamalam, it was made by him and used on his storm guns. Credit goes to him. And now one word. AWESOMENESS!!! Reliability-4.0 Since the magazine uses blue 3-d connectors, you have that millimeter sized jut on the inside of the magazine. So, the magazine sometimes jams, but you only have to push up slightly on the magazine ram. OVERALL-4.2!!!!!!!!!! Overall, great rifle. Auto-loading is a good feature, and a true trigger pleases a lot of k'nexers. Take those, and you get a gun like this. One of Bannana Inventor's best. Review by Ratchet and Clank. Gun by Bannana Inventor Thanks for reading this review! I hope you enjoyed it! Good luck building this, becouse this rifle is a must in your arsenal.

High speed bullet photography is cool - the precision of catching the bullet flying through a carefully-placed target. But how about hitting a moving target? How about hitting a single drop of water? Dutch photographer Alexander Augusteijn can do it, apparently using normal flashes, but with the timing controlled by computers. Lex Augusteijn Photography via PetaPixel

Hi Gentlemen ! i'm a old timer shooter practicing longrange shootin' to extreme distances up to 3500yds. i do shooting on metallic target that bring some more funs than the traditional paper targets. of course at such distances you will not be able to spot any system using flashing Led indicator telling if you've have hit or not the steel target. of course we can use IP camera with wifi transmission. this we do already but this is not fully sufficient. so we plan to use an impact detector (well described on instructable just type 'impact detector and you' ll get it..) and transmit by wifi the info telling the steel target has been hit or not.our impact detector is to be connected via Ethernet RJ45 port to a 5.6Ghz routeur and so on.so can anybody present us a project with an API for Android that will work efficiently on our smartphones or tablets only Androïd working? we designed our prototype around an accelerometer, a schock or vibration detector and a microphone.more details can be given of coursthe api needs to transmit the info sent by accelerometer, vibration sensor and mike.that's all we need at first. some more can be added....why not make an app that can be loaded on tabletwe have already design an outstanding system working with an HP IP camera that allow us to see the target as far as 6miles using a 5.6Ghz Wifi network. with hope to get some friendly contacts.sincerely yours, Al
Question by SHARPS1874
We all want our guns to shoot far and to fire fast, but how much performance do we actually need? Makers of Oodammo pistols boast that they shoot 60 - 70 feet, but there is no way that you can reliably hit a moving target with a knex gun at that range with any weapon, especially pistols. A good weapon should be able to fire fast, and be accurate to say 30 feet. This would allow the said gun to hit targets ar range reliably. Think about it.

The Cats page (https://www.instructables.com/id/Cats/) incorrectly states that 'Everybody loves cats'. In fact, everybody does NOT love cats, particularly those whose resent their tendency to massacre the wildlife in our gardens. I'd like to improve the odds of survival for all the birds, amphibians and small mammals in my garden, but without causing physical harm to the cats. I've tried scent-based cat repellents without success, and I completely reject the idea of indiscriminate noise scarers. I can't police the garden 24/7, so my preferred solution is a water cannon capable of detecting a cat and soaking it. To keep things simple, I'd be thinking of using mains pressure to power the water jet, and batteries to power a motion sensor (infra-red). To be useful, the design would need to: - hit targets within a user-specified arc and at varying distances - allow the user to configure the sensitivity of the sensor, so that cat-sized heat sources are treated as targets, but smaller mammals are non-targets - avoid being triggered by foliage disturbed by the wind. For extra credit, the design could: - use solar power instead of batteries - focus the jet at the target, rather than spraying mist over a large area
