I met with my new friend Recotana (Osamu Funada) in Tokyo the other week. We had a coffee, talked about Arduino and iPhone apps, and walked around Akihabara looking at parts shops. His friend Hide was also there to help. I was lucky to have them showing me around, even though I've been to Akihabara a few times he knew the good shops to visit which I'd never seen before.
I only bought a few boring things, some breadboards and an Arduino protoshield, but there is so much specialist electronics available there, it's really overwhelming.
