Great to read your post.. I am from India, based in Bangalore. Now I am going to look for innovations and stuff like that - not the FBs or the Googles but simple things that people ( who mayor may not be engineers) are struggling to come up with to make their working lives simpler, be it in agriculture or textile or leather or whatever.. but somewhere where some electronic stuff could be involved or some which would not have electronics embedded in them.
Am sure there would be some others ( the real-time engineers :) ) who would love to write to you and figure out some solutions for the problems they encounter.
I am not an engineer but I am an ordinary journalist who covers IT beat in particular but looks for human interest features in general -- and try to communicate things happening in India which are interesting to the global audience.
Maybe some ideas could help out some people - even if one person is able to add more value to his/her innovation, it would be great, I think
The battery powered ones like the one I had are relatively harmless. You could shock yourself with the arcs all day long without ill effect. Maybe we should do tiny tesla coils! That would wreak havoc on all the other electronics though.
