Ever fancied making your own satellite?Now you can! The BBC is running a challenge to build a modern equivalent of the old Sputnik 1.Do you fancy building you own Sputnik? We've given you an idea how easy it could be, now the Magazine wants to hear from willing volunteers. We can even come and film you putting it together. We'll also investigate how to get your Sputniks launched.I've already volunteered - just imagine the Instructable that could result; the first DIY website in space!

It seems incredible that the technology that went into building the first successful satellite 50 years ago can now be found lying around the average house. You could even build one yourself, as Paul Rubens explains below. Fancy having a go?http://news.bbc.co.uk/2/hi/uk_news/magazine/7049002.stm

Anyone know how to build a free-to-air (fta )satellite receiver?
can I use a satellite dish (that does not have service), as a regular antenna to pick up local channels ?
Previous owners left a satellite dish on the roof of the house - is there a way to use that dish, without acquiring service to it, as a regular antennae to pick up local channels only? thanks for any help
How would I go about creating a device that will move on its x and z axis according to an input degree?
I am looking to set up a satellite on my roof and am hoping to be able to control it from my room. For now I just need to create a base that can move on its x axis and later the z axis. I can understand for the first part I would need a motor but have no idea on how to interface it with the ability to recognise the compass degree it is facing. For the second part, I believe I may want a hydraulic arm that is hinged to the base (which the satellite lies on) but again have little idea on how to interface it with the ability to detect the angle it is pointed at. My final hurdle is to be able to control all of this. This may well be ambitious when i have little experience with motors and interface but it's something I want to do.

I received a free actuator from my friends cottage. 11 years ago it use to angle a 8ft dish. It was removed some time ago, and the label is fully off. The bottom says its a saginaw performance pak actuator, aka PPA, and it has a 24" arm. I was trying to find more information on it, and all I can find is that it can be heavy, regular, or light, 600-1,500 pounds dynamic linear. Anyone have one or any ideas? I cant find a model number on the case cuz it faded, but the motor says 7821645 or 1821645. Either way I found a tiny chart listing models but not that one.http://www.galaxy-marketing.com/images/7822260.jpgLooks similar to that one there. I just want to find out how much force it has. Most I done so far to test it works aftter 11 years of rusting on the main shaft (the moving piston is fine) is sit on a box. It manage to push me with no change in motor sound. Any more details? Please ask!

Hello everybody, I am in the process of setting up wireless internet at home, but am still a complete novice in this field. I have just bought a ZyXEL G-202 USB wireless adapter and I am making an antenna of sorts following some instructables as we speak. On my laptop I usually get 1-2 stripes at most when it comes to signal strength, so I was planning to do some piggybacking with my desktop. :) (hey, internet is not cheap here in the Balkans. :P) Anyway, I live in the capital where we have many Cafes and institutions providing free wireless, so why not make the most of it, it's not illegal here. :) The only problem is, I live in an block of flats; so many surrounding buildings tend to block and corrupt the signal. For instance, in my room (using an Acer laptop with built-in wireless) I get a list of 5-6 free (read: unsecured) APs, but the signal is so weak, it's good for nothing. :( Now, having examined my options, I was planning to make an antenna and put it on the roof of the building. But, when I climbed to the top, I found this old abandoned satellite dish SEE PHOTO (I asked around the building and nobody knows who it belongs to. Additionally, it's very run down as you can see, and the cables are torn out, so I was planning on claiming it. :p). Now, my questions are: 1. Can anyone tell me if it's a good idea to use this dish as an antenna, if I weather proof my USB receiver and mount it on the focal point of the dish? (Line of sight (aerial) distance from it to the nearest free wifi hotspot is approx. 600 meters) 2. Is there a possibility that my USB will get too hot, maybe catch fire, because of the signal boost? (Maybe this is a dumb question, but I really don't know much about these things) 3. Finally, I would also need an advice in regard to the cables needed. I already downloaded the "How to extend your USB using UTP" instructable, but since the cable should be about 60 meters long, is there a way to make it not loose too much signal? Thank you all for reading this, and thank you in advance for your advice. Any type of help is welcomed. :)

Two or three times a day, a satellite circling Earth narrowly misses destruction by an orbital hailstorm of junk sweeping the busy super highways of space.A spreading cloud of shrapnel from the collision of two satellites earlier this month is making wrecks for working spacecraft around Earth all but inevitable, analysts warn. As the ninth significant crack-up in two years -- including a punctured nuclear satellite -- the wreckage of Iridium 33 and Cosmos 2251 is fostering a chain reaction of collisions that puts billions of dollars of spacecraft and manned space flights at risk.Full article and really cool slideshow: Harmless Debris on Earth Is Devastating in Orbit - Wall Street Journal.via benjaneer.

The Kid's Chalk Art Project out on Alameda Point, CA is attempting to break some sort of sidewalk chalk drawing record. That, granted, is mildly ammusing.However, what is really interesting is that they are having a satellite picture taken of their work on Saturday, June 7. So, if you have anything you want to write really big in that general area, now would be the time do it. Thanks Tim!

Hi all, I have a small portable T.V. that will only work when tethered to a converter box. I noticed that when I attached a rabbit ear antenna to the "TV OUT" port on the box, I was able to get signal from the box wirelessly from a few feet away. I had a crazy idea that if I bought an amplified antenna, replaced the LNB on a satellite dish with it, and aimed it at the satellite closest to Earth, I would be able to have the converter box signal bounce back to the T.V. Is this even possible?

I want to receive some sort of satellite signal with a radio and then use the data I receive to control a pneumatic system to replicate a heart beating. I have been talking around with some people who know a bit about radios and the such but haven't gotten much conclusive help. I would like to build as much of this as I can myself, the entire radio and everything, though I only have about a month to do it. A DIY radio kit paired with an Arduino might be the answer due to time restraints. What i've learned so far is that I probably want it to be a tunable AM radio. Whether or not I should build that myself from scratch, build a DIY kit, or just purchase one, I am not sure. How to then interface that into a system to then control a pneumatic system, I have no idea other than the obvious arduino. Lastly, I don't need any special signal from the satellite. I really just need to receive a voltage from the radio. Though, hooking into a satellite with an onboard atomic clock so that i can then display the time as well would be great. I am going to keep doing research, though if anyone here can lend a helping hand I would be very appreciative!

I have 3 of these dishes laying around, the company who's name is on them doesn't recycle any of the outdated equipment they upgrade, told me I would have to throw them out myself... well I dont just 'throw things out'. lol So I have 1 regular small round one, the medium oval shaped "slimeline", and 1 of the larger more rectangular models (each dtv) all with the adjusting arm and all the screws. When I looked at the pile, for a moment I saw a gaming chair... but I cant quite figure out a decent design. Imagine 3 slightly different sized dishes if you can ... I'm not sure if anyone else will see the same possibility?

The dish is oval, and I am not sure if it is parabolic/spherical. Here is a picture, with measurements: http://s753.photobucket.com/albums/xx180/EternityTransfer/ I'm not too sure how this dish focuses, as it seems that vertical waves will be focussed differently to horizontal ones, due to the oval shape and that the depths are different depending on which axis is measured. I ideally want to make a parabolic microphone from this dish. There seems to be a focal point about 60cm from directly above the center of the dish, but when viewed from very off-centre angles, the dish seem to have other points too. How would I determine the "optimal" one? It is coated in a thin layer of aluminium foil, which I put on to reflect light when finding the focal point. Unfortunately there are no serial/part numbers, and the dish is missing its feed horn and support so I can't approximate the focal point form there or from datasheet(s). Any help would be greatly appreciated. EDIT: Oh and the dish originates in South Africa, and is stamped with a number which looks like a date of manufacture: 19950610. Googling the number yielded no results so its probably a date.

Hi All, First of all I'll describe the project I'm working on Then I'll Highlight my probelm 1) Description: - Now There's a boat travelling on a river. There's a satellite Receiver on the boat so passengers can watch T.V. While Travelling. The river is not straight and there're situations where the boat needs to turn 180 degrees. What I was trying to do is to have a gyro or compass beside the Satellite Receiver and detect when the satellite is not pointing to the right direction (due to the boat going on cureves & turning 180 degrees) and undo that rotations so I can keep the Satellite receiver pointing to the right direction ('cause if not so then they'll lose signal and No T.V any more :() 2) The Probelm: - I tried to use Gyro ArduImu V3 but the readings aren't helping much .. some times it's wrong and the yaw drifts a lot :( - I tried to use compass but it's not tilt compensated .. meaning that if the compass is n't on horizontal position it'll get different readings! and when they pass below some high Power Electrical lines the compass Gets crazy :( I hope you got the description & the probelm. Is there anyway else to do it? Or if there's any recommendations I'll be grateful :) Thanks in advance anyways kind Regards --- Ahmed

Oh the joy of Twitter! I just found out about this very cool contest from Discover Magazine via BoingBoing: Imagine having your own personal satellite orbiting the Earth. It’s got cameras and sensors galore, and you can use it to run experiments, take pictures, and even beam messages back to the blue marble. Well, that geek fantasy will become a reality if the ArduSat project, which you can see here on Kickstarter, reaches its funding goal. The general public will be able to rent time on this small satellite and use it for whatever they please, courtesy of its Arduino processor. [The folks] at Discover Magazine think this is pretty neat. And [they'd] like to give away a development kit worth $1500 to the Kickstarter donor who submits the best idea for an in-space experiment before July 15th, 2012. The kit includes Arduinos and an advanced sensor suite shipped to your home address, as well as one week of up-time on the satellite to run any experiment. You’ll be able to build the experiment yourself and have it be sent up on ArduSat when it takes to the skies. Here’s what you have to do to enter the (drumroll) Discover Space Challenge: (1) Fund the ArduSat project, for however much or little as you desire. You’ll receive a personal code that identifies you as a donor. (2) Read the contest guidelines here to learn about how you should design and submit your idea. (3) Enter with this entry form, making sure to include your personal code. (4) Wait for winners to be announced on July 20th, after judging by Discover blogger Phil Plait, Discover Editor-in-Chief Corey Powell, and an expert panel of judges. (5) Rejoice!

I need a hardware volume leveller/normalizer for analog audio from cable box to tv. (schematic or product)? Answered
Searching around I've found several shareware software programs - installing an extra computer for this task isn't an option. Ibles doesnt seem to have anything like this... I'm thinking an arduino, a sneaky sketch, and an lm-series stereo volume regulator. All the hardware I've seen dies a quick death - presumably the way of the electric car - too much lobbying from advertising industry to stop them hitting store shelves. Frankly, I think its beyond un-ethical. In my particular situation, its potentially dangerous.
