Decided to swap the electrician for Arjan by promising him a RC plane if he manages to fix my electricity (at € 25 a plane they're a lot cheaper than electricians). Arjan did some poking, removed a ceiling lamp, removed the cover above it and found out that for some reasons two wires had shorted. Sadly this happened in a place where quite a few wires passed to quite a few power-outlets (read all of the kitchen outlets, a wire to the shower and some other wires to other places in my house. This means a whole lot of rewiring. Guess I'll have to buy Arjan a real plane now.
Still I'm very lucky that Arjan wants to take on the job, having to pay for a "proper electrician" would have been a whole lot more expensive.
