The following excerpt is taken from the homepage of TheHackerspace:
"Unless you are rich, it is unlikely that you own all the hardware and the tools required to build different kinds of embedded systems. For example you might already own an arduino board, but most probably you are missing the X or Y sensor required to build your favourite prototype.And unless you are a genius, it is unlikely that you know everything about all the available free software/open source operating systems. Thus, perhaps you wrote your own system call or driver for the Linux kernel, but most probably you don’t know how to do the same stuff on another operating system that you like (for example MINIX 3).Don’t worry. That is exactly why we founded TheHackerspace. It is a place where hardware, books, code, and knowledge is shared between people who like to hack. If you are interested on embedded and system hacking, you are welcomed to join us."
Personally I contributed in many ways to the foundation of TheHackerspace by helping to build the lab, donating books, writing most of the (current) content in the homepage, etc. Unfortunately I don't have the time to enjoy TheHackerspace since in a week I'm relocating to the Netherlands where I got a job (but that's good news!). I hope that when I'm back in Thessaloniki TheHackerspace will still exist and some really great projects will be the outcomes of its foundation :)
