I came across a cool kickstarter project called Circuit Scribe that allows you to draw electronic circuits with conductive ink on paper using a pen.

This is really fascinating, because it allows you instantly prototype without using breadboard and it is also a very cool way to teach electronics to kids.

Each pen costs around $20 (plus shipping) and I am buying at least a couple of them.

If you are in Bangalore and are interested in this, then let me know. We could save money shipping cost by ordering a 5 or 10 pen bundle.
