DIY Ionic Plasma Thruster Built with a Homemade Transformer Inspired by NASA aerospace engineering, this project features a plasma thruster, designed to maximize efficiency and increase the voltage output. For that, Maker created a homemade ionic plasma thruster to harness the high-voltage generators (50,000+ volts) to accelerate ionized gas and create thrust. This experiment is based on how electrons collide with neutral gases to form… |

Espressif Shuts Down “Backdoor” Hysteria: ESP32 Debugging Feature Misrepresented as Security Threat A recent controversy has emerged around Espressif’s ESP32 microcontroller, following the discovery of undocumented Bluetooth HCI commands by security researchers at Tarlogic Security. Initially described as a "backdoor," this characterisation sparked significant debate and was later revised to acknowledge these commands as debugging features rather than a deliberate security vulnerability. The… |

Interfacing a Digital Caliper with Raspberry Pi to Measure CNC Lead Screw Accuracy A hobbyist assessed CNC lead screw accuracy by building a setup using digital calipers interfaced with a Raspberry Pi. These calipers transmit data via a 76 kbps synchronous serial protocol, requiring precise timing. Python proved inefficient, so the code was rewritten in C for better performance. The calipers output two 24-bit… |

DIY AI Camera with ESP32-CAM That Analyzes and Describes Images DIY enthusiasts have made an AI camera that, instead of displaying images, reads the images and gives a description about them. For doing so, it sends the image to an AI, which then generates a text description of the scene. The description is displayed on a small OLED screen, giving users a fresh and creative way to "see" the world through AI’s perspective. The camera comes with multiple… |
