Not seeing anything at http:\\www.ardusat.org yet. Is that the right link?
For what it's worth, computer hardware flown in space is specially radiation hardened and redundant. The radiation environment in space is different than that at the surface of earth, i.e. there is a significant one. Some information:http://en.wikipedia.org/wiki/Radiation_hardening
Radiation hardening is a method of designing and testing electronic components and systems to make them resistant to damage or malfunctions caused by ionizing radiation (particle radiation and high-energy electromagnetic radiation), such as would be encountered in outer space, high-altitude flight, around nuclear reactors, particle accelerators, during nuclear accidents or nuclear warfare.
Most radiation-hardened chips are based on their commercial equivalents, with some manufacturing and design variations that reduce the susceptibility to radiation damage. Due to the extensive development and testing required to produce a radiation-tolerant design of a microelectronic chip, radiation-hardened chips tend to lag behind the cutting-edge of developments.
I am not sure anyone would fly non-radiation hardened computers. Also, I don't think any of the off-the-shelf commercial sensors would be all that useful for scientific experiments, but who knows.
