From zero to live IoT in one hour. We’re excited to welcome Raj Nakarja as a speaker at Techheads 2026. Raj spent a decade building IoT the hard way, custom hardware, bespoke firmware, wrestling with wireless connectivity, and stitching together cloud infrastructure before a single line of application logic could be written. So he built Silicon Witchery to collapse all of that into one system. Connect a sensor and, instead of a dashboard, just talk to it in plain English. In this hands-on session, you’ll build a connected IoT sensor from scratch. No prior hardware experience needed, just basic programming knowledge and a laptop. You’ll be given a Silicon Witchery S2 Module and a handful of sensors. By the end of the hour, your device will be live on a cellular network, collecting real data, and responding to questions in plain English, all from a web browser, no toolchains, no cloud setup, no infrastructure to wrestle with.
