Show HN: RF Hunter – Find hidden cameras and other devices (github.com)

Article summary

The RF Hunter is a device designed to detect and measure RF signals in the environment, useful for finding hidden cameras and other RF-enabled devices. It is built using an ESP32, AD8317 RF detector, and other components, and displays the signal strength on an OLED display. The device can be assembled with a bill of materials costing around $100. The creator has made the project open-source and is open to improvements and feedback.

What commenters say

• The device's effectiveness in detecting hidden cameras and other RF-enabled devices is dependent on the antenna used and the environment in which it is used.
• Some commenters believe that the use of game cameras and other surveillance technology is an invasion of privacy and can be used for nefarious purposes.
• Others argue that game cameras can be a useful tool for wildlife tracking and conservation, and that their use is not inherently problematic.
• There is a discussion about the potential for the device to be used with a Flipper Zero, and the creator is considering making it compatible.
• Some commenters are interested in purchasing a pre-assembled version of the device, and the creator is considering selling them at a price point of around $100.
• The use of technology to detect and counter surveillance is seen as a necessary measure by some, given the increasing presence of hidden cameras and other surveillance devices in public and private spaces.
• There are differing opinions on the ethics of using technology to detect and evade surveillance, with some seeing it as a legitimate means of protecting privacy and others viewing it as an attempt to cheat or circumvent the law.
