### Need help from archery/ siege weapon people?

So im planning to make a ballista for a school project. I haven't learned all that graphing stuff yet, so how do i determine the range of a projectile launched according to it's angle launched, mass of prjectile, and draw weight? i suppose it would go somewhat like (Mass of projectile) x (n constant) x absolute value of ({angle launched - 45 degrees} x k constant ) x draw weight x g constant sorry, im not good at math. would it work if I just flung projectiles and recorded distances and graphed that? or would I have to calculate each thing seperately? please help

### The best of Office weapons

We have all at one time built a weapon out of a pen. There are plenty of Instructables under office supplies that cover booby traps, launchers, and even siege weapons. But some are repeated. Which are the best? Which need more? You decide.

### Ancient History: Kite bombs

From the article:   We investigate the kite bömb - a never before built medieval siege weapön that dropped bómbs from a kite over cities. We build one and test it with startling new insights and success. We investigate ancient bouncing bõmbs that actually skip across water - ... Source of article.    I saw this on the Ancient Discoveries. Over the weekend I believe, on TV.   The key to stability was a long tail...... Here is a source of information given to me by Kiteman,  concerning the Ancient Kite Bómbs (arial attacks before the airplane or balloon).

### How Can I Improve My Catapult? Answered

So I built a mangonel (torsion catapult) for science olympiad, and it must launch a foam ball up to 15 meters. But, its struggling to reach 10 meters. I was wondering how I can make it launch further, whether changing the tension of the torsion bundle, different rope, or even structural changes. I will gladly accept any and all suggestions.

### Featured I'ble not showing on front page or withthe snazzy banner?

Hullo all... I received the email telling me that I am awesome... and indeed that my I'ble on Trebuchets is also of the same calibre... BUT... It doesnt appear to be showing up on the home page... nor does it have the little white diagonal banner that says 'Featured'... that my other featured I'bles have... I assumed that it was just due to updates and filters and such... but the time stamp on the email shows that I was featured at: 17 April 2010 00:17:43GMT   I show up in this link: https://www.instructables.com/play/?show=FEATURED Decided to take this to the forum as I was unsure who to email... or If its part of the new site re-vamp? Let me know Jay did no one ever learn that its not wise to mess with the person holding the siege weapon??? ;)

### Revolutionary Knex Gun Competition 3

"Necessity is the mother of all invention. Competition is the mother of all necessity." -Oblivitus The Challenge: Build a weapon that can survive being dropped as many feet as possible without breaking (30 or 50 feet for example). You will need video proof for this (the best way to do it is probably to throw it up in the air, DON'T HIT ANYTHING). Remember that how well it fires is also very important in this competition. Rules: 1. You may enter as many knex weapons as you like. 2. You may not enter siege weapons. Criteria (in order of importance) -Performance (how well it fires) -Innovation (how many feet it can be dropped from without breaking) -Appearance A weapon that was posted before the beginning of the contest will decrease its chances of winning. Grass is fine for dropping the gun on. However, dropping the gun on a harder surface will score bonus points. If the gun survives falling on more than one section (for example; on drop one it falls on its barrel, and on drop two it falls on its stock) the gun will score bonus points. Deadline: August 1st. Judging: I'll pick the winner. Rewards: The winner will receive my 5 star rating on their slideshow or instructable. The real prize, however, is the satisfaction of winning. The winning weapon will be announced in a forum on or shortly after August 1st. Entering The Contest: Post a link or photos of your weapon on this forum to enter. I will be posting a new contest near the beginning of each month until further notice.

### My 2cts on the new Featured Instructable system

Hello everyone, it was suggested that I give my thoughts on the current (new) system when an Instructable is Featured. Recently one of my Instructables was Featured (have a look at my Trebuchet I'ble). I received the standard 'We think your awesome' email... and then... nothing I waited for a snazzy little banner proclaiming to the world that I was featured... I also waited to see my Ible on the front page... After 24 hours I got worried and posted a bug report, where the new feature was explained to me Where I have the problem is this new three teired system hasn't REALLY been explained in an email or a site update memo.. Perhaps It would be useful to have an opt-in site update email which explains the current features/updates of the website? Another problem is the email I received says this: Hi! Your Instructable "Scout Project: How to build a Trebuchet" was just featured by one of our editors! Being featured means we think you are awesome. Keep up the great work! Look for your featured Instructable, within the next 30 minutes, here: https://www.instructables.com/play/?show= FEATURED https://www.instructables.com/play/siege-engines/?show=FEATURED Eric The old style email says: Hi! Your Instructable "How to make: Norbert the Cuddly Squid" was just featured by one of our editors! Look for it on the Instructables homepage within the next 30 minutes. Being featured means we think you are awesome. Keep up the great work! https://www.instructables.com/ -Eric There isn't very much difference, and when you are unaware of the change, it is a little confusing... maybe the standardised email needs a little tweaking for the new Featured Instructable system? Thanks alot Jay

### What Should I Make Next?

Alright I have ideas but I have no clue which I want to do. So I'm simply going to ask you guys. Which of these should I make? By the way check out my TDS Instructable I updated it with a simple slide mechanism. Compact Assault Rifle Like an AK-74u or an XM8C. Basically I want to try to make a small gun that has some good strength. (an exact gun you want me to do would be helpful) Power Weapon/ Sniper I dunno this is something I really wanted to make for a long time after getting some more pieces. I've had I don't know at least 4 or 5 failed attempts before I don't like what I'm making. I have yet to make a weapon simply dedicated to power. Another Side Arm My TDS is great and all but it could have been a lot better. Basically I'll try something new and see what I get. Crossbow I suck at these...and that's why I want to try it out. It's another thing that I think a knexpert should have along side a side arm and sniper. What I would plan out then is a repeater so it has a magazine. Siege Weapon Something else I was curious about. A catapult or maybe a scorpion although it would probably just end up being an even smaller version of I_a_C's cannon. I'm not to enthusiastic about this one. Other Gun Replicas I guess I could try to make other replicas of bigger weapons but unlike the compact assault rifles they'll most likely be more for looks than function. Any Combination of the Above? I don't know maybe a cross bow pistol the handle loads sounds kind of cool although it would sure be a challenge. Or if you have other ideas tell me. Those were what I could think up at the moment and would be willing to do.
