Technology is moving fast these days. REALLY fast. Phones are getting bigger and better. For a reasonable fee the average Joe can now enjoy a 3D experience from the comfort of their home; and now the Circuit Scribe wants to make learning about and creating circuits much, much easier.
A gel pen filled with conductive ink, the Circuit Scribe lets you draw circuits that dry instantly, meaning you could create a working circuit among the notes in your notebook.
Amazing! I bet my micro-electronics teacher at high school wishes he had one of these on the day he accidentally submerged his hand in an acid bath, thus effectively killing off all the nerves instantly.
Time, it seems, is still a cruel mistress.
