This post will cover recent uses of the NRF24L01 with the EPS32-Cam module. An earlier example used an the NRF24L01 module attached to an Arduino Uno, a laptop, and a logged putty session, details can be found here, https://www.cloudacm.com/?p=3836. This configuration had limitations due to its size, the required pieces of equipment, and operating steps. The purpose of this scanner type is to survey 2.4Ghz radio transmissions. The NRF module can detect power levels across the band and store those…

In this post, we’ll explore how to incorporate the ESP32-Cam module into a spectroscopic setup. There are numerous online resources that demonstrate the construction of a basic homemade spectroscope designed for visual observation. The following video utilizes readily available materials. https://youtu.be/fW4aMOSVv_8 The primary focus of this post centers on assembling the hardware for our spectroscope. We’ll leverage code from previous projects for the ESP32-Cam module. In a prior article, we employed the spectroscope to analyze the intensity of an RGB…

This post will provide some experiences with the Kauf RGBWW Smart Bulb and firmware developed with the Arduino IDE.  Details about these bulbs can be found on GitHub, https://github.com/KaufHA/kauf-rgbww-bulbs or from the manufacturer’s website, https://kaufha.com/ I referenced this post about the bulb, https://digiblur.com/2021/09/15/preflashed-esphome-tasmota-smart-bulbs-with-an-added-bonus-kauf-blf10/.  It mentions that a new firmware can be uploaded through the device web interface.  My attempts to upload firmware compiled in the Arduino IDE were not successful. Initially I thought it was an incorrect OTA flash size…
