All it took was a siren and suddenly people paid attention.
Early in my career, I knew a woman who had a medical condition that confined her to an electric wheelchair and made her speech quiet and hard to understand. When she was in a crowd, it was hard for her to navigate through it because people did not see or hear her.
I built her a simple two transistor siren that could be attached to the chair and was operated by pushing a momentary push button. When people heard that siren (it was not loud) they moved out of her path. She was tickled with it.
That was one my first few circuits too. Much before I studied engineering, since my childhood I was passionate about building small electronic gadgets by referring to books/magazines which used to publish hobby circuits. Even though I did not fully understand how that circuit worked, I built that circuit with two transistors and a small speaker form an old radio. My friends and I had fun with that for some time.
At some point in the life of a technology startup company, the CEO and the founding team will be confronted with the question of whether to sell the company or not. Hopefully, the question arises in a positive context and comes from an interested buyer driven by the opportunity to deploy the new technology to a much larger user base.
The IoT, wearables, and 3D printing-focused Designers of Things conference has also partners with the IPSO Alliance to call on entrepreneurs, makers, students, and professional engineers to submit designs using IP.
