This post will cover how to build and operate a honeypot run on the ESP8266 platform, specifically the ESP-01 module. The enclosure for the project will be a prop that resembles a brain in a jar that is lit by a LED strip to represent operational conditions. The ESP-01 module will connect to a defined network and run common network services. The module will subscribe and publish MQTT messages to a broker for various conditions, states, and controls. The module…
This post addresses the problem of servicing ESP based systems that have been installed. I have built systems where the ESP module is fixed, enclosed, and installed in a location that is difficult to get to once in place. As time progresses, so does the realization that some features will need to be updated on those installed ESP modules. Over The Air updates are the ideal way to update the modules without the hassle or downtime. Here is a detailed…
The ESP32-Cam module is an inexpensive platform that can be developed for many purposes. It does have some drawbacks. Compiling with the Arduino IDE can be much slower compared to native AVR platforms. Another issue is the “Brownout detector was triggered” message on the debug window. Slow compilation was covered in another post, https://www.cloudacm.com/?p=3998. This post will explore some ways to deal with the brownout fault. When the ESP32-Cam module boots, it will perform a series of checks and either…
