This is the Reaper...it may not have great look, but it sure is effective.This one uses 4 strings of rubberbands and has a really sturdy trigger which also may be a new design.Sorry for the bad pictures...all i had at the moment to make a picture was an ps2 Eyetoy. https://www.instructables.com/id/Reaper-Crossbow/It is finished!

So i thought i'd start a thread on Metal foams. For those of you that don't know what it is i offer the following links: http://en.wikipedia.org/wiki/Metal_foam http://www.metalfoam.net/ Looking through the forums, I figured this could be something pertinent to a DIYer's interest, since metal foams, specifically Aluminum foam, is strong, light, and relatively cheap. The fact that it marries with advanced composite materials science is kind of an added secondary bonus. I'm personally interested in this sort of stuff because i want to make an ultralight aircraft and this stuff could be used to accomplish that... but that's sort of something that's tangental to most that'd find info on Foamed Aluminum interesting.

Well I finally got some more pieces, more still coming; this enabled me to build something bigger =dThis crossbow(more like cannon, now) has the following specs:Ammo: 1 Standard arrow, which needs to be ductaped other wise torn to shreds.Weight: 4,5 kilo's (9,92 pounds)Range: Not tested outside, will beat the Reaper and the Blockhead for sure.Rubberbands: 32, 8 strings of 4 ( these may still be increased as it shows no bending yet.)Power: Just look at 2nd picture....should explain a lot.Trigger: Same as on the Blockhead, some big improvements on it though.(Surprised about how power much it can take...)Sturdiness: Seems close to unbreakable lol...Without realizing..I also made a very good scope on it o.oI had a purple+blue 3d connector as arrow tip and when I fired on my cardboard box, it made a huge tear...and my ears were ringing like from an explosion O.o'Well this monster has bad points:Need a long/strong left arm if you are right-handed, because this thing is heavy as hell.Cannot fire without trigger.Every arrow needs ductape otherwise connector gets torn off.Also I gonna try and say...:I think this may very well be the most powerful ranged k'nex weapon on this site at the moment.

What material could you use to make strong seats out of this?

Pictures have been taken, Instructable will have the Y-shaped bow and a normal shaped one. Stock and scope will be optional. And uh...yes these things actually hurt...I shot a few arrows into my own leg..just so I could feel how much it would hurt xD Instructable will up soon, need to find some time to write it.

I have an old army jacket that doesn't fit me anymore, and i think it would be cool to turn into a backpack, i did the Tim Anderson and Star waterproof test on it and barely any air gets through, i also have an old backpack with broken straps i can use, what do you guys think? Any ideas are appreciated. BTW, my touchpad went out on my laptop today.

I been experimenting with projectiles, and been wondering what can I use to simulate a human skull. I've been shooting at a 1\2 inch thick peice of wood board, the projectile made it all the way through easily. When aimed at someones head, do you think this could peirce the skull and damage the brain, or do you think the bullet will just get stuck? How strong is the human skull anyway?

I'm trying to build a bed loft type thing similar to this I'm thinking about using pvc pipe though because its cheaper/easier, but my only worry is if it will hold weight. I want to put a hammock on the bottom (occasionally 2 people so ~250lbs) and a piece of plywood on top to make a shelf. Thanks

Hey guys, I am not much of a knex guy, but I made a strong trailer for my RC truck to pull around at the campsite to collect firewood (just sticks haha) anyway I made a knex "adaptor" for the car, but I cant figure out a way to make a strong connection between the car and the trailer. Can someone help me out???

Here is my take on the Oodassault-Pistol By TheDunkis.Link: https://www.instructables.com/id/Oodassault-Pistol/Before I start, I'd like to highly recommend it.Trigger:Strong,Realistic,and reliable.Also has a safety, and is very innovative.Mag:Small, but it is very reliable. Note that it is slow to reload.Is also very new.Handle:Not much to say, but it feels good,and is very sturdy.Barrel:It looks iffy, but it is really good.The bullets fly extremely straight, and are pretty powerful.Overall:Innovation: 10/10 Almost all of this gun is 100% TD.Accuracy 10/10 I can hit a small target from 20 feet using the sights. Trigger: 9/10 Feels great, and is very reliable.Strength: 8/10 Like most 3-layer pistols, it could be broken quite easily.Range: 8/10 It shoots quite far, and maintains it's accuracy.Comfort 8/10 Trigger feels very good, and so does the handle.Reload: 8/10 The mag is slow to reload,but it is VERY reliable. Mod room: 8/10 This gun could have many mods for various reasons.It is built so you can easily change things like: Change ammo type (?)Add longer barrel, stock...etc.....Looks 7/10 It's not very realistic, but it looks cool.Raw Power: 7/10 Oodammo tends to be not very damaging, but it more than makes up for that with it's accuracy.83/1008/104*I love this gun. Love it.But the mag is too small and slow to reload.This makes a great sidearm, but just don't plan on reloading this while running away from the enemy.Link: https://www.instructables.com/id/Oodassault-Pistol/ It would make a good gun to make two of then have a mini war

Hey guys. i'm making a desk that's 90in x 30in x 30in.. i will be using a piece of MDF that's 94in x 30in x 3/4in. i plan on using 2 x 4's for the back and right side of the frame and screwing them to the wall studs. the rest of the frame will be made with 2 x 2's. i plan on using the space mainly as a computer desk. fully loaded i'm estimating about maybe 100lbs on the desktop at one time. i attached some pictures of the my current plans for now as well as the sketchup file. so that you guys know what i'm talking about.. my question is.. do you guys think the frame is strong enough to hold the desktop and about 100lbs of random stuff. thanks in advance.

I am wanting to create a fun RFID / NFC device that will detect when different people walk into a room. We all have individual RFID door tags to open a door so I was wondering what the range was on RFID, would the person need to tap their fob or is RFID strong enough to detect if somebody is just carrying the fob in their pocket? If the RFID isn't strong enough, could I use something in their phone to detect them? Bluetooth maybe? Everybody has an iPhone, could I detect something on that? Any thoughts? Thanks. Phil

It's got some strong language, but I find it very well done. !Strong language in places & he doesn't like it, at all. Erm, not really suitable for children, I'm thinking again about this, but maybe no one young will go past 5 min...?

Hi, I want to build a rotating mechanism powered by a spring. Once released,I need the piece to make 2 rotations in a fraction of a second. I also need it to be quite powerful since it will have to push another piece. For this application, I believe that a coil spring (such as those we can find in clocks) is the best suited, but will it be powerful enough ? An if I use a torsion bar spring, the problem is that I probably won't find one that can make 2 turns.... they are usually designed to be used on small angles only. I would be glad to have your advices ! :)

Hi, I would like to buy a ring from Shapeways but before buying it in silver I would like to buy it in plastic to see if I actually like it on my finger so I was wondering if someone would be able to paint it for me. The main colour would be silver with a little bit of green and blue on the face. As for the paint I was thinking of enamel or acrylic depending on which would last longer. Would anyone be interested in doing this? Side note: Would I get a better response by having this thread in the Art section of this forum?

I want to make a "magic" staff which will power on a strong (>100 lumen) LED under a crystal in the top of the staff. There will be a hidden switch somewhere and I want the LED to power up/down in approximately 1-2 seconds. The power source has to be relatively small batteries but big enough to power the LED for up to 30 minutes. I believe this can be done simply with just a capacitor and a resistor connected to the LED but since I'm a complete beginner, I'd like some advice. 1) How to connect parts together. 2) What parts to choose? I can calculate the timing from t = RC (or is it root of RC?) but there are soooo many to choose from. Probably the LED needs to be fully powered at 3 or 6V. Probably the resistor therefore needs to be 100-500 ohms? Probably the capacitor needs to be approx 2 - 20 mF? But it would be so much simpler if someone says: "Take these components - that will work". I guess choosing the batteries will be crucial for both size, voltage and current conciderations. But please note that I want the LED to be as strong as possible - flash light strength. 3) Is it possible to have a faster power down than power up (0,5 s rather than 2 s) without overcomplicating things (and crowding the space provided). The space is probably no more than an inch diameter (2-3 cm) cylindrical hole for a maximum of 3-4 inches (7-10 cm) length. All help appreciated!

I know there are already instructables that show how to build a PVC flagpole, however what I need to build is different. I want to build a flagpole that is 15-20 feet tall and can withstand relatively strong winds. In addition, it needs to be portable and be able to be disassembled, so the sections of PVC can be no longer than 5-6'. I am worried that just using standard PVC connectors to connect the different sections will not be strong enough to withstand the wind. This flag will be placed in the sand on a beach facing the ocean, so a 15-20' tall flagpole will need considerable strength. I figured I would use a 5 gallon bucket filled halfway with cement as the base, and then bury the base in the sand so it is sturdy on the bottom. From there, I am having trouble coming up with alternative ways to attach the sections of PVC (besides connectors) that will withstand high winds and not snap. Do you think the connectors will in fact be strong enough? If not, are there any good alternatives? Lastly, would drilling holes into the PVC (to attach eye hooks) compromise the strength of the PVC too much?

Ibuilding a custom car body out of polystyrene foam. Any advice on what to cover the foam with to strenghten it. I was thinking abot fiberglass but was really hoping to avoid it if possibe. Any suggestions on a strong alternative to fiberglass would be appreciated.

I need to grind some kno3 but i dont have a mortar and pestle or a coffee grinder. is there any way to improvise using household items? by the way, the kno3 is pretty strong stuff, so it will take some force to grind it. any ideas?

Hey guys, im am not a huge fan of knex, but i decided to use my collection for this build i'm doing. I am working on a Logging trailer for my RC car. I have the knex hock up for the car itself and it is very strong. I didnt even have to glue it or anything (I was pretty proud, haha) anyway, I build a strong frame for the trailer, but when too much force is applied the stick pieces come apart from the connector pieces. I had idea to inertwine sting in between all of the pieces to keep its shape, but I wanted to know if anyone else had any other ideas. Thanks P.S.= if it is needed to get a better idea, I can try and post pictures of the trailer.

This is Killer~safecracker's winchester review: looks:4,5 looks like a real one,and there is no blue rod sticking out the body. comfort:4,5 realy comfort. innovation:3,0 nothing to new. piece usage:3,5 uses quite a lot of piece,and some people dont have flexible bleu/white rod strenght:3,5 the stock is a bit weak,but the rest is strong enough. power:4,5 it has a lot of power for a replica,but its a slingshot,and slingshot have a lot of power. accuracy:4,5 it has a realy good accuracy! reliabilty:4,if you have not to strong elastic,your a good go total:4 realy good gun, build it now and give him a sub!

Here is the review for the OSSR ( Oodammo Slingshot Sniper Rifle ) by DJ Radio.What to expect: Innovation: 7/10 I think There isn't really anything to innovative but it's the first official Oodammo slingshot.Strength: 9 /10 the gun seems strong there are not any major weak spots.Range: 8/10 shot a good 90 feet Looks: 9/10 I really like the looksParts: 8/10 it has a good part to range ratioHandle: 6/10 the handle is a bit small and not that comfortableStock: 9/10 nice and sturdy. I like it.Barrel: 8/10 the barrel is strong and sturdy.At the end: I would give the gun 8/10.Here is the link to the gun. https://www.instructables.com/id/Knex-OSSR/Thanks for reading
