Ok time is running short and while the proposals are good we're not yet there; I understand the brief can be complex, just dont worry about discussing doubts.
Now we have two ways to improve:
1) Focus on the concept "from a circuit drawing to a functioning", where the circuit drawing could be anything from here

Ideally in the logo the circuit drawing "morphes"... evolves... into the functioning.
2) Alternatively we can focus on the idea of community of electronics technicians. So the focus would be on people and the sense of community with a stronger web 2.0 look & feel. One proposal touched this point.
Anything, just tell. Really, i mean it.
Thanks a lot
