DIY Spray WiFi fractal antenna – Sierpinski Gasket

Homemade WiFi fractal antenna. “A fractal antenna is an antenna that uses a fractal, self-similar design to maximize the length, or increase the perimeter (on inside sections or the outer structure), of material that can receive or transmit electromagnetic radiation within a given total surface area or volume” (Wikipedia) Inspired from “White Collar” 2×10 episode […]

#43 ESP8266 Range Test with and without External Antenna

In this video I test how far away an IPad can connect to an ESP8266. I use two scenarios: One with a normal ESP-12E and its PCB antenna, and a second scenario with an ESP-07 and an antenna from an Access Point. CNLohr’s video: https://youtu.be/7BYdZ_24yg0 Swiss Atomic Bomb Shelters (for those who do not believe): […]
