There are two papers recently published in Eur. J. Phys. that highlight a rather interesting web portal. The web portal is called Remotely Controlled Laboratory, hosted at University of Technology Kaiserslautern in Germany. The two papers on EJP (which you can access 30 days after they appear online) are:
1. "Experimenting from a distance in the case of Rutherford scattering", S. Gröber et al., Eur. J. Phys. v.31, p.727 (2010).
2. "A collection of problems for physics teaching", S. Gröber and H.-J. Jodl, Eur. J. Phys. v.31, p.735 (2010).
It's an interesting website with useful standard and "historical" problems.
