In 1898, years before radio broadcasting existed and decades before anyone used the word "electronics," Nikola Tesla stood in front of a crowd at Madison Square Garden and did something that looked like magic. In a large pool of water sat a small iron-hulled boat. With no wires connecting them, Tesla sent commands through the air and the boat obeyed, turning, stopping, and blinking its lights on demand. Spectators were so unprepared for the idea that some accused him of hiding a trained monkey inside the hull, or of controlling it with his mind. What Tesla had actually built was the first wireless remote control, and it is the direct ancestor of every connected device we make today.
A machine that took commands through the air
Tesla called his invention a "teleautomaton," from the Greek for "remote" and "self-acting." The boat carried a radio receiver, a set of relays, and a battery driving its motor and rudder. From a control box on the side of the pool, Tesla transmitted radio signals that the receiver decoded into physical actions. Press a control, and a coherer-based circuit closed a relay, which in turn stepped the boat's steering and switching mechanism to a new position.
The patent behind the demonstration, US Patent 613,809, "Method of and Apparatus for Controlling Mechanism of Moving Vessels or Vehicles," was granted in November 1898. Read today, it is startling how modern the thinking is. Tesla was not just wiggling a boat around a pool for show; he was describing a general system for sending control signals to a remote machine and having that machine act on them without a human physically present. That is the exact problem statement behind modern IoT, just with vacuum-era hardware.
Why nobody knew what to do with it
Tesla saw enormous potential. He imagined remotely piloted vessels, automated vehicles, and machines that could carry out instructions from miles away. He even pitched the concept to the US military as a radio-controlled torpedo. The reception was cool. The technology was so far ahead of its context that the people who might have funded it could not picture a use for it. Radio itself was barely understood, and the notion of trusting a machine to act on invisible signals struck many as a parlor trick rather than an engineering breakthrough.
That gap between invention and application is a recurring pattern in technology history. The same wireless-control principle would eventually reappear in garage-door openers, television remotes, drones, and industrial automation. But in 1898 the surrounding ecosystem of reliable radios, compact power, and cheap logic simply did not exist yet. The idea had to wait for the rest of the stack to catch up.
The direct line to modern IoT
Strip away the brass and the coherer, and Tesla's boat is doing exactly what a connected device does now. A sensor or a control surface generates an intent. That intent is encoded and sent wirelessly. A receiver on the far end decodes it and actuates something physical: a rudder, a relay, a valve, a motor. Every smart switch, every remotely managed industrial controller, and every fleet of connected robots is a descendant of that single loop of "send a signal, move the hardware."
What has changed in the intervening century is not the concept but the economics and the layers on top of it. Tesla needed a hand-built receiver and a room-sized imagination. A modern engineer reaches for a two-dollar microcontroller, a Wi-Fi or Bluetooth radio, and a lightweight protocol like MQTT, and gets far more reliable remote control than Tesla could have dreamed of. The addressing, the security, and the cloud dashboards are new. The core act of steering a machine you are not touching is not.
Building on a 125-year-old idea
There is something useful in remembering how old the fundamental idea is. When a client asks whether a piece of equipment can be monitored and controlled from anywhere, the honest answer is that the concept was proven in a Manhattan exhibition hall in the nineteenth century. The interesting work today is not proving that remote control is possible; it is making it dependable, secure, and affordable at scale, from the silicon up to the cloud.
That is the work we do at Fluidwire. Whether you are prototyping a connected product, wiring up sensors for a thesis project here in the Philippines, or bringing an industrial system online, the challenge is the same one Tesla was solving on the water in 1898, just with better tools. If you have a device you want to make smart and remotely controllable, get in touch and we will help you close the loop from silicon to cloud.
