Sugar gliders?

Hi all, Does anyone else keep sugar gliders? I have 3 and make a lot of my own pouches, bonding pouches (as shown below) and toys out of coconuts, piñatas etc.  Are these things that would be of use to anyone as a tutorial? I think ferrets and rats would use pouches too, but the patterns would have to be bigger. Piñatas would work though. Any thoughts? One of my friends did say that she would use my Batpouch as a clutch bag, so maybe I should post them anyway.  LMAO :D

Glider Part That Makes Gliders Glide? Answered

From the title, I'm sure you can tell that I'm absolutely ignorant about what this part is or how to replace it.  Basically, I have a few gliders with broken bits that are supposed to make the gliders glide.  And because I have no idea what this part is, I've taken a few pictures. I'm wanting to fix these parts, but I don't know the name of the part and, consequently, where to find them.  Brah!!!!

How to create wings for human flight?

All of us have seen humans fly in those triangle shaped gliders. How about creating wings that will do the job? Understood that it requires more than wind to propel it so flapping power could be harnessed.  I need designs and the physics(i.e How much area of wing is required to lift what mass of body and etc.) Please suggest solutions ASAP!

[Idea] - Styrene Glider Modification

I propose a modification of easily obtainable Styrofoam glider's allowing longer airtime VIA a small electric motor. To be successful, the modification must be light weight, cost effective and use minimal tools so smaller children (I think of myself as a big kid) can repeat.Before you go off on me for this not being an instructable - read this: https://www.instructables.com/id/EYD12YXN3XEP2873DL/ -- I'm going to try and breathe some life into the idea :PI'm thinking I'll find a personal fan (might be hard considering it's winter time :P) and start there. If I recall, those fans are directly driven and use one or 2 1.5v batteries. I think it can handle reverse polarity at 9v.I'll bore out a hole in the nosecone for the motor and hot glue it in place. If possible, I will place the 9v battery aft of the wings -- attempting to preserve the center of gravity.In the video below, when my buddy says "Test 2" that is the second test using his glider (after the fuselage cracked off on a hard impact). His wingspan was 12 inches shorter, and his glider was heavier. The video was recorded with an ATC 1000 helmet camera*** and hastily thrown together.*** I lost some footage -- on some impacts, the camera "froze" and the video did not save. I had to pull the batteries to get it going again. I suspect the memory card got jarred and the camera didn't know what to do with it. Or, something completely different. This only happened 3 times even though the "test 2" portion of the video was a vertical impact.Suggestions and Feedback welcome :)

How can I lift a 38kg hang-glider wing on to my van's roof-rack (without help) without breaking my back? Answered

Hi, I fly a microlight, the trike of which fits nicely in my van (see link). The wing folds into a sausage shaped, zip-up bag, which can be carried on a roof-rack made by bolting a ladder to the roof of the van....but getting it up there is an issue. I can get help from a neighbour when I set out, but I am on my own at the airfield, when it comes to getting the wing down....and later putting it back up.I have wondered about a pulley system, a stepped system, a winch, etcanyone got any suggestions?http://tinworm-wings.blogspot.com/all help very much appreciated-Tinworm

African Makes Paraglider From Plastic Bags

Awesome.Cyril Mazibuko grew up in the shadows of the mountains. Born in a small kraal at the foot of the Drakensberg range in the southern part of the KwaZulu-Natal province in South Africa, Cyril would often look up at the 3,000-meter basalt peaks, a playground for African paragliders. Enthralled, Cyril made a decision: He would build his own glider and join them in the sky.Now 26, Cyril is the only black South African currently registered with the sport's ruling body. And it all started with a glider he made from plastic bags, purloined rope and baling wire, a glider that flew -- sort of -- though it both amazed and horrified the professional paragliders who saw it.

Knex Flight

Seeing as knex is light, strong and flexible, and most importantly, using rods, I beleive it would be feesable to build a Knex 'glider'. After seeing how gliders are made, it could be possible to build a lightweight spacframe wing out of knex, and make it fly using clingfilm as its 'skin'. An extra boost of gliding power would come from a clingfilm propeller, powered by the very fast and smal, solar motor. Do you think it is possible to make something like this glide 10 metres? Ideas welcome.

What do i consider while making a flying machine? Answered

For a while i've been studying, designing, and building hang gliders. To my great disapointment however, none of them have even glided. I am starting to think there are more things to consider than just center of gravity, balance, and the over all "lightness" of the craft. Are there more things i should consider? I have also pondered upon the idea to make a Ultralight Helicopter, or somthing along those lines. What are some things i need to consider beond what i've already mentioned?

Paper Airplane Contest (Closed)

In hopes of seeing more paper airplanes and innovative designers on Instructables.com, I have decided to host a mini-contest. My goal is to stimulate the paper airplane channel and encourage more paper airplane builders to post their innovative designs.  Performance Requirements: Entered paper airplanes must meet or exceed these requirements: Stability at all operation speeds A minimum range of 30 feet Durability to fly 30 feet or more after 15 flights Use of less than 15 pieces of tape in construction Use of less than 5 pieces of 8.5 by 11 inch (A4) paper in construction Prizes: For this contest I will award the publishers of the top 3 paper airplanes* one patch each. By default, these patches will be medals (1st place, Patch with Gold Medal image; 2nd Place, Patch with Silver Medal image; 3rd Place, Patch with Bronze Medal Image). If the winners of the patches would like a different image, there will be a 24 hour period between the announcement of the winners and the awarding of the patches. During this time, the user would need to send me a private message with their desired picture. *Multiple entries are allowed. To keep the distribution of patches wide, each entrant can only win one prize. How To Enter: To enter this contest, you must send me a private message with your instructable's URL included. I will then put the link and author's name onto a list on this topic as "Entries". Judging: For this contest, I have decided that I will judge all the planes myself based on abilities. I have decided this way because I believe judging on performance rather than shape is a more objective approach. The contest begins Friday, December 10, 2010 and end Monday, January 10, 2011. Entries must be published before Tuesday, January 4, 2011. From January 4 to January 10, I will be judging all entries.

Paper Airplane Contest 6 (Closed)

To coincide with the publishing of my one hundredth instructable, I am hosting a sixth paper airplane contest (PAC6). However, unlike my previous contests, this one is aimed at origami aviators just beginning their flights. Although the previous “PAC5” has yet to conclude, I feel it is an appropriate time to start up another contest, due to the different aims of the two. For this contest, the specification is for a trainer paper airplane. Requirements: 1. Aircraft Requirements: • Ability to fly at least 25 feet (7.62 meters) from a launch height of 5 feet or higher • Durability to fly at least 25 feet, at least 15 times • At least two of the following must be featured on your aircraft: flaps, elevators, rudders, ailerons, spoilers, elevons, decelerons, spoilerons, flaperons, air brakes, slots, and/or slats • Allowed materials include: 2 sheets of 8.5 by 11 inch (A4) paper, 8 inches of Scotch tape, scissors, a stapler, 5 staples, a ruler, a pencil, pen, and 2 paper clips • Aircraft must be named 2. Instructables Requirements: • 1 page (not the intro page) devoted solely to materials required in construction • 1 page explaining how to fly the aircraft • The instructable's license must be: "Attribution Non-commercial Share Alike (by-nc-sa)" • This sentence and link must be displayed on your entry's intro page: “This instructable is an entry in Paper Airplane Contest 6 (https://www.instructables.com/community/Paper-Airplane-Contest-6/)” Prizes: For this contest I will award the publishers of the top 5 performing paper airplanes* one patch each. However, unlike previous contests, each patch will feature its respective aircraft, rather than medals. The first place winner will also receive a 3 month Instructables Pro membership. *Multiple entries are allowed. To keep the distribution of patches wide however, each entrant can only win one prize. How to Enter: To enter this contest, you must send me a private message entitled “My NGT Paper Airplane [Member Name Here]” with your instructable's URL included. (The “NGT” acronym refers to Next Generation Trainer, in order to distinguish it from PAC5 entries). I will then put the link and author's name onto a list on this topic under "Entries". Judging: I have decided that I will judge all the planes myself based on abilities. I have decided this way because I believe judging on performance and suitability, rather than shape, is a more objective approach. The contest begins Friday, June 17, 2011 and ends Friday, July 15, 2011. Entries must be published before Friday, July 15, 2011. From July 16 to July 18, I will be judging all entries.

What LEDs for a light signalling system that needs to be visible at over 1000 yards?

I'm building a light signalling system for a gliding/soaring club that will be used for indication to the winch driver. This is done by means of flashing lights where the on/off timing indicates the launch phase (take-up-slack, all-out or stop). The original plan was to use car spotlights (2 x 55W) but I am considering LEDs. Assuming LEDs would be suitable for this application (I have no experience of using high intensity LEDs) can anyone enlighten me (pun intended!) on what would be the best type to use i.e. colour, brightness, quantity etc. The light will be located at the launch point (i.e. where the glider starts from) and needs to be easily seen by the winch driver who is over 1000 yards away. It needs to be usable in bright ambient light conditions e.g. on a summer's day (yes we do occasionally get them in the UK!). Thanks

80.000 nose dive autopiloted

Hi all, I'm planning to drop a glider from a weather balloon from about 80.000 feet. I want to let the airplane gain speed and then glide to the launching place or at least as close as possible to it. The idea is to do a nose dive (nose heavy) until enough speed is reached and slowly turn the airplane towards the launching site. Is this achievable with ardupilot software? I'm already sending a bunch of instruments like gyro, gps and magnetometer and I could use their readings on a Raspberry pi to run ardupilot , at least until video range is available to switch to manual. If possible I want to avoid buying the autopilot hardware 1. Any idea if this could be achievable the way I'm going about it? 2. Is this even legal? (I know it has been done already but I'm planning on doing this many times) Thank you in advance for any answer backed up by facts.

Wiring a 2 way radio headset to also record audio?

I am a hang glider pilot and like to take videos during flights. I would like to add narration and the back and forth communication with my chase driver as part of that. I have a headset in my helmet that is wired to a ham radio for that communication. The jack to the helmet is a three conductor, 1/8" jack that goes to the earphones, microphone and a common ground. There is a push to talk switch that trips the radio to transmit which is between the helmet and the radio. What I would like to be able to do is put a jack/splitter inline with the existing jack to then go into the mic jack on a voice recorder to get three things; Radio audio (receive), Radio audio (transmit) and me just talking into the headset mic - Narration.Not sure how well I am explaining this and I could just experiment, but I am thinking it's not as simple as just wiring stuff together. I'm good with a soldering iron, but no EE by a long stretch. Any thoughts? Thanks

How can you connect an LCD screen to a YSB001 (MD80 rip-off) camera so you can see what you are filming?

When you film with a good video camera, you can usually see what you are filming by looking at the LCD / viewfinder... but I have bought one of those very cool, tiny cameras that cost about £10, can be bought on eBay and which come from Hong Kong But in return for being tiny, it does not have any kind of viewfinder. I bought mine to experiment with fixing it to my hang glider/microlight to film flights. I figure I can, by trial and error, work out what the actual field of view/ frame is but I'd much prefer to be able to set up my camera with a monitor of some kind (perhaps using my mobile phone camera?) Better still, I would like to be able to monitor the camera all through the flight (perhaps be able to move the mount remotely?) Is there a simple method for achieving this or do I need to do electronics?

dc to dc step up converter for 22v 6 cell lipo to get to 44 volt , need advice

Im building a power harness for my hang glider, the project is very near completion, my brushless out runners require 44 to 48 volts. I am using two sets of 22v 6s in series, but the weight of two large 6s batteries banks is significant , what would be the potential to create this step up converter and what are the down side of designing dc to dc step up converter into my power system. My hope to eliminate the in series battery ( double battery  weight ) set up.  I suspect loss of amps or total run time ? what about problems with electronics  heat in the circuit, issues with ticky speed controllers, or the out runners , how will they be effected , or will these components work normally in a step up voltage / current  as compared  batteries in series. ( which is working beautifully ) I guess volts are volts, it just sounds to good to be true , double volts and less battery weight Any and all qualified opinion and advice is appreciated.  Thanks Jeff

Homebuilding of experimental aircraft?

Hello Instructables I am a professional aerospace engineer who homebuilds aircraft in my garage when not doing so for work.  I live and work at the Mojave Airport which is a hotbed for aircraft homebuilding stretching all the way back to the 80's.  The experimental aircraft community does not have anything like what you all are doing on this website.  When I found your site the first thought was that I had finally found the place to talk about buillding airplanes.  But I see no such topics on the site.  While fundamentally I assume the problem is only that the channel has not yet been created or there is a liability problem, I wonder if there isn't more to it.  Is the thought of designing and building and flying your own airplane not as awesome for others as it is for those of us who live in Mojave?  Is there something that can be done to make this exciting world more exciting to people (like yourselves) who take such pride and make such investments in doing cool stuff in your garages?

Geting started

I would like to help people start building and flying model aircraft! I started flying unpowered gliders with my dad at the age of 5 by the age of 8 I could do figure 8ts with the same model of unpowed glider, then I moved to my own plane a wingo which is a great durable slow park flyer, the kit comes with every thing you need except for a controller, servos and glue. I put a brushless motor and a lipo battery with this setup I could fly strait up until you could barely see the plane (about a mile high). After that I got my first 3d trainer a ucando which is also durable and constructed with hot glue!!! So far I have crashed into a blueberry bush and torn wings to pieces, but I am in the process of gluing back together.I prefer electric models over gas or glow models; their cheaper, quieter, smaller and more durable. Here is a great place to find beginner and advanced electric planes. Their are also different types of kits, ARFs (Almost Ready to Fly) are my favorite type of plane they include most of what you need for the plane inside the box, most only take 2-6 hours to complete and dry. Much easier for beginners to build and not mess up. Normal kits have only parts and dont usually include motors batteries or any thing else, they can take weeks to build but can be much cheaper. And theirs a third RTF (Ready To Fly) more expensive than ARFs but most of the time all you have to do is charge the batteries! You should visit your local hobby store to find out more about the local clubs and flying fields it is illegal to fly some sized planes in naborhoods I am not familiar with all the laws but I only fly at flyingfeilds. A plane like the warp would probly be fine to fly in your back yard or naborhood field. You should know that making model Rc planes can be addictive, expensive, and when you crash and destroy what you have been working on for a month extremely frustrating.Join the AMA and your local flying club, model aviation is a great way to make friends and meet new people, oh and its fun! For all ages!horizon hobby is a group of hobby stores. hobby store locatorIf you have any Q's please ask!Id also like to start a list of good trainers the yard stick is not as durable as the wingo but can be found every werethe wingo a great beginer ucando a 3D trainer (get a wingo first)

I will then put the link and author's name onto a list on this topic under "Entries". Judging: For this contest, I have decided that I will judge all the planes myself based on abilities. I have decided this way because I believe judging on performance rather than shape is a more objective approach. The contest begins Friday, May 27, 2011 and ends Thursday, June 30, 2011. Entries must be published before Thursday, June 30, 2011. From July 1 to July 3, I will be judging all entries. I will announce the winners of the contest on Tuesday, July 5, 2011 and issue them their prizes Wednesday, July 6, 2011. Entries: DJ Radio: "Super Bullet" (https://www.instructables.com/id/The-Super-bullet-Possibly-the-fastest-paper-air/) The Skinnerz: "Goose" (https://www.instructables.com/id/Goose-Paper-Glider/) heavyfire88: "The 50 Calb."

How can I make a giant bike cog like this one? Answered

Here's a site with  the inspiring article: http://www.cnet.com/news/fast-fixie-bicycle-with-giant-chainring-aims-for-100-mph/  Anyways, I want one. First of all I would suppose I'd need a pattern. What program would you suggest I used to make a pattern?  A solid circle of metal with teeth on it will do. I'm thinking of gluing a pattern to a piece of metal, cutting it out as best I can with a grinder then going bike to clean it up with a tungsten carbdide dremel bit. I gues it could be a few thinner sheets of metal that could be  spot welded together. I dont have any tech shops/idea foundries in my town. I say that because I'm wondering could I just create some type of file that a mill machine could read and cut it out for me? I have a couple different reasons for wanting a larger cog, the practical one being I want a cog large enough that the pedals would be moving around very slowly so you could just shift your weiht back and forth, more falling with your body weight than pedaling. The 2nd reason, more lofty and long term goalish is if you can get this much power from a bike, to propel it 100 mph, it just seems reasonable that a human powered aircraft is within reach, as in attatch a hang glider to a bike and have the pedaling able power a propeller once airborne. Anyways, how would you go about making a giant cog?

K'nex Challenge 2: 18th Sept - 11th Oct - FLIGHT

After the success of the last contest, Gmjhowe, =SMART= and myself decided we'd go for it and launch a second contest.The first we really enjoyed and saw some awesome entries. This time we've decided to make the guidelines a wee bit looser so you can use your imagination more. We'll be setting a category for you to design and build within and then provide you with some example ideas to get you started. And this category is....FLIGHTAnything plane, helicopter, glider, flight related is allowed. Please read the rules carefully.Rules:Your entry must do something. It can't just be a model of a plane or a helicopter. We want them to move or glide or have spinning parts or be functional for something else around the house but be aircraft themed.Entries must be over 50% knex. The remaining can be paper, glue, card, tissue paper.... anything!To enter, write up a full instructable of your construction process with clear pictures and descriptions. Post the link here.Please steer clear of guns. That's not what this is about.Starting and closing dates are GMT.What the judges say goes!Have fun!Judging - 12th Sept - 18th SeptSuggestions:A propellor. Small and compact, if you design a good one you might get extra kudos if your design's then used in loads of other entries.A ceiling plane. With a plastic propeller on the front and the top attached to a string to the ceiling, this plane will fly itself around in circles on a string.Paper plane launcher. Probably the closest you'll get to a gun.A vertical launch rocket. Rocket being a rocket model not a meagre collection of rods.While knex by itself might not be light enough to fly.... perhaps you could run some string through the middle to make it appear to glide.... Mum's washing line might be of great help.Prizes:There will be patches for prizes. Gmjhowe will be uploading them soon.

Camera Stabilizer (Physics related)

I had an idea for a camera stabilizer a while ago which involves some basic rules of physics. I've done some thinking on it and I can't seem to figure out if it would really work or not. It involves two principles: 1.) Torque (t=f*d) 2.) Inertia (p=m*v) ---- The idea is to combine a gimbal design found on camera "gliders" like these: -Commercial product: http://www.bhphotovideo.com/c/product/521721-REG/Steadicam_MERLIN_Merlin_Camera_Stabilizing_System.html -Homemade design: http://www.diycamera.com/stabiliser/index.html ...with some sort of see-saw to counter the effects of up-and-down motion.  Ignoring the fact that this might be somewhat hard to hold such a thing, I just want to know if this would work. ---- Any balanced see-saw will have an equal amount of torque on either side of the pivot point. Therefore, a balanced see-saw will work with 500g hung 10cm from either side of the pivot point, OR 750g 5cm from one side and 250g 15cm from the other side (750*5=3750; 250*15=3750).  With this concept, I thought of designing this part of the stabilizer like a small camera jib (http://en.wikipedia.org/wiki/Jib_(camera)). That is, the camera on one end with a counterweight on the other. The pivot point would have a handle or some kind of vehicle mount on it.  The stabilization occurs (or so I'm thinking) because of inertia. Inertia=mass*velocity. So, when the pivot point (the handle) moves up or down, one of the sides of the see saw should move up faster than the other. The side that moves up slower (the longer side of the see saw, I'm thinking) should have the camera mounted to it.  ---- Is there a flaw somewhere in my thinking? THE QUESTION: Would both sides of an uneven length, balanced see-saw move up at the same time when the pivot point is moved up or down? I'm not really sure and I'd like to hear your input.
