Kite Plans
- monk_e_boy 7y agoHenry Hulk, wow, haven't heard that name in years. Nice designs. No kitesurf kites though, probably the most popular kites on the market now? Maybe in the west, not sure about the east.
- TimTheTinker 7y agoDon’t forget the middle. There are many excellent spots for flying kites away from the coast. One of my favorite kite shops is out of Boulder, Colorado: Into The Wind[0] I’ve only bought from them once or twice, but I used to spend hours paging through their paper catalog as a kid. I also visited their shop in Boulder as a teen — that was really fun. [0] https://intothewind.com https://intothewind.com
- thefifthsetpin 7y agoMy brother got his daughter a kite from there. The wind didn't cooperate on the first day we went to fly it, but her dad and I still tried getting it into the air by running with the string to see if we could get it high enough that it'd catch what wind there was higher up. We failed, but my niece saw us running with the kite, so she wanted to run with the kite. She had a great time running around the park with the kite bouncing on the ground behind her. The kite survived that & flew fine on later occasions. Now that she's seen it fly, though, she has lost interest in kites that won't fly.
- seraphsf 7y agoWhen I was 10, the Into the Wind catalog lit my imagination in so many ways. It was a fantasy novel crossed with a science book. A couple years ago I wandered past their store in Boulder and was floored that there was a real, physical incarnation of that magical catalog. I took my little kids there this winter and it was like passing a spark between generations.
- mxfh 7y agoMaybe in market value with all the gear that comes with it, but unlikely by numbers. Regular kite festivals still draw massive numbers anywhere in europe and casual or kid kites are still at thing. Regular kites where really huge in the late 80s and 90s for some weird reason, with any bigger town in Germany having at least one dedicated kite shop.

- Toadsoup 7y agoEdit: I can accept that kite plans can be on topic for HN. I also don't mean to stifle anyone's curiosity about kites or kite building. I suppose I expected something more akin to "Kite Plans, Experiments, Observations, and Results that SoAndSo ran" or "Specific Kite Plan and Notes" to be linked on HN. If you're new to kites, good news, it's a lot more fun than it should be. --- Original Post: I am confused, why this link is on HN? I enjoy kites and have used this site before, but what makes it worth the front page of HN? It's nothing new, their site hasn't really changed in years, and it is somewhat off topic. Was the poster just fired up about kites? Am I missing something?
- RobotCaleb 7y agoI'm curious what you consider on-topic.
- moftz 7y ago"Bitcoin Miner Docker Image Written in Rust Running on a Model 3"
- tonyarkles 7y agoIt definitely meets the “satisfies intellectual curiosity” criteria for me! I think we’re giving it the HN hug of death right now (or my phone internet sucks here), but I’ll definitely be checking back later and maybe building one this weekend. Kites are pretty cool and, as this site points out pretty dramatically, can go from super simple to technically very complex and interesting.
- erdosjr 7y agoApart from being fun, there is a good amount of engineering in designing kites. For example, NASA has been experimenting with designing simple parachutes [1] and it turned out that the parawings (or Rogallo wings) are pretty good traction kites, too. The NPW kites are still popular kites as they are cheap to make and long-wearing in use. [1] http://2e5.com/kite/nasa/reports/ http://2e5.com/kite/nasa/reports/

- slacka 7y agoWhat's the deal with the sketchy "PDF viewer" that they tried to force Chrome users to install? This is an example where a site actually worked better in Firefox and Edge.
- groovybits 7y agoChrome, Firefox and Edge all come with PDF viewers by default. You do not need to install anything. Rule of the internet: don't install things that you didn't ask for.
- fouc 7y agoWhen I think of kites, I always think of my dream of a kiteboat for long term cruising around the world.. purely kite powered, with maybe a small stabilizer sail if necessary.
- losvedir 7y agoThat's interesting. What would be the advantages of that over an ordinary sailboat?
- pacaro 7y agoMy understanding is that there are a variety of advantages: the kite flies in cleaner air; the thrust from the kite is applied at one point, with less heeling moment than from a sail; the design of the boat is not constrained by the structural requirement of a mast IIRC A kite powered boat called Jacobs Ladder held various sailing speed records at one point

- trillic 7y agoI’ve a feeling that upwind performance would be lackluster. A modern Bermuda rig can be highly performant at all points of sail in a variety of conditions.
- simonebrunozzi 7y agoCan you elaborate a bit more on the Bermuda rig? Curious.
- jdmichal 7y agoBermuda rigging: https://en.wikipedia.org/wiki/Bermuda_rig https://en.wikipedia.org/wiki/Bermuda_rig If you're not familiar with sailing rigs, you probably don't even notice it as anything other than, "that's what most modern sailboats look like." This is precisely because it is a extremely efficient at sailing upwind. And their fastest speeds are roughly doing perpendicular to the wind. Boats like you see in pirate movies and such have what is called square rig. These boats will sail their fastest downwind, but struggle much more in other directions. https://en.wikipedia.org/wiki/Square_rig https://en.wikipedia.org/wiki/Square_rig EDIT: So I just realized that the Wikipedia article does not have a great explanation on the actual physics here. I'll do my best, though this is all subject to my (mis)understanding. Obviously, just putting a sail on a raft with no other modifications will just push your raft downwind. You have some ability to control direction with the rudder, but that's it. To sail perpendicular, you need to start leveraging other forces. The main ones are lift force from the sail shape, and drag from the centerboard. [0] Bermuda rigging uses a triangular sail that is rigged along the axis of travel. (Compare to square rig, where the sails are perpendicular to the axis of travel.) The sail has enough slack that, as wind fills it, it curves. The sails then begins acting as a vertically-oriented wing, using the airflow over the surface to generate lift -- though, in this case, the lift pushes the sailboat sideways. So you have the wind attempting to push your boat sideways... That is not helpful for moving forward. Enter the centerboard, which resists this push by simply increasing the surface area of the boat under the water. In order to move sideways, the water has to be moved. So you have two opposing sideways forces, and the result is a bit like pushing a wedge -- the boat moves forward. Also of interest in the physics is speed. So a boat sailing downwind can never go faster than some fraction of the wind speed. Because if it was, the apparent wind would either be zero or a headwind. However, a boat moving perpendicular or upwind can actually move faster than wind speed, because it is utilizing more forces than just the raw wind. And, in fact, the faster a boat moves upwind, the faster the apparent wind is, moving it yet faster. [0] https://en.wikipedia.org/wiki/Centreboard https://en.wikipedia.org/wiki/Centreboard Really small boats might get away without one. For example, a Hobie Cat (around 16 feet) is using a combination of its hull and a large rudder surface to achieve the same effects.
- Xunxi 7y agoNASA's exhaustive Kite index which covers the physics and Math of Kites. There is even a KiteModeler and interactive simulations for anyone who is interested https://www.grc.nasa.gov/www/k-12/airplane/shortk.html https://www.grc.nasa.gov/www/k-12/airplane/shortk.html
- minikites 7y agoBefore drones were widely available, I attached an inexpensive camera to a kite to take some aerial photographs. I'm a little surprised that wasn't more common, given how popular drones are now.
- kijin 7y agoPerhaps the limiting factor was the lack of inexpensive cameras, not the lack of drones. There was only a short window of time between when remotely controllable lightweight cameras became cheap enough for people to not worry about crashing them into rocks, on the one hand, and when drones became widely available, on the other.
- shaftway 7y agoNot that narrow. I remember in the late 80's / early 90's Estes had a model rocket that would pop a picture (onto film) from the nosecone when the chute charge went off. I have no idea what the quality was like (my parents refused to buy me one).
- fotbr 7y agoI spent a bunch of allowance money on one of those. It used 110 film cartridges, and had a pretty cheap plastic lens. Quality wasn't really that good (and wasn't helped by the cheap film I had to use), but it didn't matter to a 10 year old -- I had a rocket that took pictures!
- shaftway 7y ago10 year old me is super jealous.
- chadmaughan 7y agoAgreed. We got around this by hacking the single use CVS/Rite Aid cameras according to the below guide. Dropping one of these in the water or on some rocks didn't feel quite so devastating. https://makezine.com/2008/02/29/how-to-cvs-video-camera-h/ https://makezine.com/2008/02/29/how-to-cvs-video-camera-h/
- conroydave 7y agoi always feel slightly bad for websites like this that HN brings hugs to death, even though ad supported, its normal users are unable to access their content
- paulie_a 7y agoWhy? It's not like this will be permanent, a few hours probably. And many sites exist without ads. What's there to support? A few dollars a month in fees?
- kingnothing 7y agoThe large effort to actually build and curate the content.
- pushpop 7y agoFor personal sites like that, curators often do it for the love of the subject rather than a financial reward. Hence why some personal sites are hosted without any adverts. Edit: I see I’m getting downvoted a lot for this comment. I appreciate creating content for the love of it might seem like an alien concept to many HNers but not everyone is driven by the motivation of turning every hobby into a start up. In fact once upon a time, in an era before Facebook and Google, the majority of an average persons surfing time was spent on non-commercial personal web sites.
- TaylorAlexander 7y agoThat’s how my sites are run. No ads, no tracking. I put free 3D printed robot designs up as well as my personal writing. I do all of that stuff because I want to and I want others to have it. Ads are gross. So I don’t know why you’ve gotten downvoted, but your comment rings true for me.
- hahamrfunnyguy 7y agoKite building is a hobby I've always wanted to get into.A buddy of mine has build a few of the NASA-style Regallo kites. He uses them with his icebuggys. Apparently, they're not too difficult to make and icebuggys are a blast to pilot.
- TACIXAT 7y agoI was thinking recently that kites could make great signaling mechanisms for backpackers. It would be relatively light in your pack and can get a location noticed if you got lost. I'll have to dig through this site for simple designs that are easy to keep up in the air.
- TremendousJudge 7y agoSounds useful but in limited situations -- open fields (so no forests) and windy but not too windy
- silentguy 7y agoHelium balloon would be a better option. Release it with other end tied to your backpack.
- ElijahLynn 7y agoSite is DDoSing right now because of this.
- mirimir 7y agoI love kites. Just seeing the word, I remember the boy-as-a-kite-on-ice-skates from The American Boy's Handy Book[0] 0) https://images-na.ssl-images-amazon.com/images/I/81LstaapceL._AC_UL320_SR226,320_.jpg https://images-na.ssl-images-amazon.com/images/I/81LstaapceL...
- SamPatt 7y agoKite building is actually fairly easy, and can be very inexpensive. With just wooden dowels, fabric, simple sewing and simple rope & knots you can have something flying in a few hours. Takes a while to get the hang of troubleshooting the problems of flying, but the basics aren't complicated. Good cheap fun.
