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?

Large-caliber Sundial

I was wandering the web, looking for information for a future Instructable, when I got ever-so-slightly side-tracked.I came across this blog entry about a bunch of people who made their own, rather unique, sundial:Our friends in the village are building a garden from scratch, to go with their new house. A key part of garden planning is to get the major design "features" sorted out ahead of the planting. One of the things that the boys wanted was a sundial, so work has started there. The plan follows the traditional method of sundial construction, as you will see from the pictures:1. Buy a World War II anti-aircraft gun (preferable the portable kind)2. Put it in the garden.3. Make sure the safety catch is on.4. Invite some like-minded nutters round for a barbecue and get them working the elevation controls.5. Set the barrel to exactly 52 and a bit degrees elevation (to match the latitude of the garden).6. Do some nifty work with a calculator and a compass to figure out where the hour markers go for precise "Northmoor Time".7. Unilaterally declare independence - and if anyone argues....:lol:Link to Blog

I bought 6 metres of ripstop nylon for my blimp envelope. What is the best way to seal the edges?

I've tried glue, duct tape, and a bit of heat sealing. It doesn't really work.

Dentist radiation chart

Living in a rock or brick house exposes you to 700 times the radiation as eating a single yellow banana ! A BBC chart shows a banana as 0.1 radiation units and rock/brick homes as 70 radiation units and flying a trans continental aircraft is much worse in exposing you to radiation...

Dude plans to jump from a plane and land on his belly. Really.

Jeb Corliss has leaped from buildings and other places in a single bound. Now, he plans to do it without the aid of a parachute.Corliss, who is a base jumper, has made jumps in 16 countries and five contents, more than 1,000 in all, from the likes of the Eiffel Tower and Golden Gate Bridge.His latest venture is trying to jump from a helicopter and land without using a parachute.Corliss says he’ll wear a wing suit, which makes him look like a flying squirrel. He plans to landing on a specially designed runway he designed. It will cost up to $2 million. Once he gets the funding for his project, he says it could take up to four months to actually pull off.He added, “A wing suit, basically, is fabric that goes between your arms and between your legs and it changes the shape of your body. So you become, in essence, a flying squirrel.'He explains that he plans to land on his belly, suggesting, "œImagine an aircraft. Aircraft don't land on their tails, they land on their bellies. That's exactly what I'm gonna become. I'm gonna become an aircraft. I'm gonna be landing on my belly.Why in the world would Corliss try this?"œI wouldn't say I'm doing this because I'm a thrill-seeker. I'm a person who has dreams and my life is based on making those dreams come true. And that's what I focus on."

Can we fight back Big Brother?

Conoy Township in Lancaster County, Pennsylvania; is voting to avoid flying surveillance remote controlled aircrafts above their skies. In a time when the United States government approves the use of drones to spy on the civilian population, I have found interesting how people are responding. This municipal ordinance definitely will not stop the use of drones on this area if deemed necessary for our national security but I wonder if this could be the start of a trend.

Americans bomb Kiteman: miss by sixty years.

A Royal Navy bomb disposal unit has been called to an unexploded bomb discovered on a Suffolk beach.Experts in the unit think the bomb was dropped by a US aircraft in World War II, while returning to an airbase.Houses and schools within half a mile of the site at Felixstowe harbour have been evacuated while the unit works on the device.As I type, a bomb-disposal expert has been on the TV to say it may be a 500-pounder.BBC storyLocal pressEDIT: It's a German bomb, not American. You can tell your lawyers to relax.

For those who are interested

OK this is my first forum. I have been following instructables for a year now but have never joined. I love DIY stuff and everything like it. I recently went to sacramento for thanksgiving. On the way back my faimly and i started to have one of those random road trip conversations. The topic of people who attach hellium ballons to lawn chairs came up. There was a movie about this a while back i dont know what its called but im not interested in that. I told my parents that i would have done it if i had the chance. Then my father and i came up with an idea to make an ellite hellium aircraft. We would take away the longchair and other variables. The end product would be somthing where i would have an oppen cockpit with hellium ballons tied to each corner and two 12inch fans in the back for sterring(the fan size may change) What im asking for is suggestions for ideas what type of materials the cockpit should be the list is endless im just asking for ideas Money is not a problem i have a finacial contributer that will pay for everything After i am finished with the prototype i will make another one and then post an instructable about thank you Public Enemy No.1
