Make Your Own Sputnik

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.

    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.

The biggest deal is that a hit was un-predictable, if I recall it was like a 20% chance of a hit within 3 months, for the size of the palm pilot. The big deal was a hit often turned a component into a conductor (or even a super conductor), so we had to add tight over current protection (even for just AAA batterys) to keep it from burning up if the wrong component went.

      Basically I think most consumer electronics would last in space for months, as long as the temperature issues were kept in check. As I recall it was also only a issue if the device hit a powered circuit (or a memory area, could theoretically cause a bit flip). Of course the way odds work, it could be destroyed the first second powered. The memory corruption issue was solved by storing our program on flash memory card, so a reboot would bring the program back.

      As you say, they can't be shielded (realistically) so they would affect non consumer electronics the same as consumer electronics. So I assume the only way to solve this is through redundancy which becomes more of a software issue, than a hardware one.
