Make Your Own Sputnik

Posted by CmdrTaco on Mon Oct 22, 2007 10:21 AM
from the because-you-can dept.
An anonymous reader writes "What better way of celebrating the 50th anniversary of Sputnik than by making one of your own. The BBC says that you can build your own Sputnik satellite from stuff lying around the house. The BBC quotes an electronics hobbyist: "Technology now is way ahead of what was available in 1957, and making your own fully functional Sputnik would now be very simple indeed. I wouldn't be surprised if you could build one in a container smaller than a matchbox, weighing about as much as a wristwatch. The components, including a transmitter, battery and the sensors you'd need would probably cost less than 50 pounds [about 100 US dollars]. It really shouldn't be a problem to build and program the whole thing in under a day." Unfortunately, the BBC article doesn't go into technical details." And of course, actually getting it up into orbit might take a little more work.

      Exactly and changing the "beep" depending on temperature was not "programming" but how temperature worked on resistors to the timing circuit. Sputnik was 100% analog.

    • Sputnik actually HAD science instruments: it encoded pressure and temperature inside the capsule in radio pulses. This allowed to verify that there's no big danger of micrometeorits in space.

        Actually, there was another important scientific discovery that sputnik allowed. It was designed to transmit on two different frequencies, 20MHz and 40MHz. Since different radio frequencies are affected differently by the ionosphere, it was possible to observe things about the ionosphere that wern't possible before such as its electron density.

    • Sure there is... if you have a Scaled Composites workshop in your backyard and a place to store the volatile chemicals... mind you, range safety become an issue... you'll have to check your neighborhood association charter to make sure you aren't violating any rules, for things like towers, radio antennas, satellite dishes, etc.

      You might, given the fact that you only need to carry a "matchbox" into a low orbit. But it will still be a hell of a job and lots of trail and error. The bigger problem you will have is that you will have to do it without hitting anything (civilian jets, satellite's, etc), as it might set you back a few hundred million dollars if you manage to do so.

  • Perhaps they should be encouraging someone to create a powerful electro-magnet satellite sweeper to surf the orbital zone and "pick up" the junk that is whistling around out there, rather than encouraging Joe Average to add his own litter to the fray.

  • Good luck getting the fan to do any "cooling" in space. And with today's instrumentation efficiency, there's probably not a whole lotta need to worry about cooling.. I'd be more worried about keeping things heated above -40 deg C to maintain operating temperature.
    • Yeah, the article implies that the original Sputnik had a fan as well. If the case was hermetically sealed then maybe this would work.

      There is also a balloon for pressure/leak sensing so looks like the intent is for the unit to be sealed.

      I would just use a hacked cell phone (cost much less than $100USD) that calls me once an hour or so to give me the temperature etc.

    The article is not remotely about building a sputnik, but it is about how technology in sputnik served similar purposes to things used in the home. Using a baby monitor as a transmitter? a domestic thermostat? a balloon? a mercury thermometer? "4x large batteries"? come on. This sounds like the losing science fair project of a seven year old.

    I'd be careful about saying that. While nerds may be in a minority everywhere they are found, in aggregate they are still a numerous and clever breed prone to accepting challenges like that. DJGPP came about because Stallman said it wasn't possible to run gcc under DOS. The thought of hundreds of thousands of sputniks in low earth orbit is scarey. :)

    If you work with Amsat [amsat.org] you can have your work shot into orbit. There are about 18 currently in operation [amsat.org], with launches starting in the 60's [amsat.org]. Amsat is an international organization.
    • The very first non-government satellite was AMSAT's own OSCAR-1.

      The very first secondary payload was OSCAR-1. When other people thought they might be able to hitch a ride in to orbit the way AMSAT did, the Authorities suggested they look at how AMSAT did it.

      The free rides in to orbit aren't as plentiful as they once were, but are based on one of two things: either stuff little satellites in to areas of the launch vehicle where "real" satellites won't fit, or take advantage of launch vehicles having exce

    Oh, that old meme.

    Trivia: What is the probability that off-the-shelf microelectronics (like wireless routers) will work in space? Answer: Roughly zero.

    Why? Look at the information starting at page 23 on this document: Spacecraft Charging and Hazards to Electronics in Space [nyud.net]:

    3. Radiation Effects on Spacecraft Electronics

    The radiation sources discussed are hazardous to electronics since energetic particles can deposit energy inside microelectronic circuitry and disrupt their proper operation. Energy deposition in electronics is measured in rads(M) where M is a specific material being considered (1 rad = 100 ergs/gm). Energy deposition can be in the form of ionization or atomic displacements, which can permanently damage electronics, or it can be in the form of single events, which can cause transient or permanent damages depending on the severity of the event.

    NASA doesn't ship Xeon processors into space, not because of budget cuts, but because they don't work reliably (if at all) in space.
