Build a four-wheel RC car with ESP32-CAM board and off-the-shelf parts

ESP32 CAM robot car with off-the-shelf parts

While there are plenty of ESP32-based wireless-controlled robot cars with a built-in camera, like the PiCar-X 2.0 or Zeus Car, it might be more fun and rewarding to build something yourself. That’s exactly what Matt Sroufe did by building his own RC car using off-the-shelf parts and an ESP32-CAM board and writing firmware for it. To get started with the build, you’ll need six main components: A 4-wheel car chassis – $47.49 on AliExpress Electronic speed controller  – $5.27 on AliExpress. Matt selected the 30A version with green PCB. Dual-battery holder for about $2 on AliExpress 2x 18650 3.6V cells or 7.4V batteries purchased locally ESP32-CAM board with an external antenna and the 160° FoV camera – About $14 with board, camera, and external antenna. Bluetooth gamepad such as a PS4 controller The total should be around $80 with the batteries assuming you already own a Bluetooth gamepad. You’ll need […]

Polverine – A compact, mikroBUS-compatible environmental sensing platform with PM 2.5 and gas sensors (Crowdfunding)

Polverine mikroBUS sensing platform

Polverine is a mikroBUS-compatible environmental sensing platform featuring a BMV080 PM2.5 sensor and a BME690 gas sensor, plus an Espressif ESP32-S3-MINI-1 module to add Wi-Fi 4 and Bluetooth 5 connectivity. The onboard BMV080 sensor is described as the “world’s smallest PM2.5 sensor” at 4.2 x 3.5 x 3mm. The PM2.5 particulate matter sensor is complemented by the BME690 which measures temperature, humidity, and pressure, and detects volatile organic compounds (VOCs) for complete environmental monitoring. The board offers sufficient processing power for quick data handling, with wireless connectivity for easy integration into IoT systems and smart devices. Projected applications for the sensor platform include indoor air quality monitoring, smart homes, HVAC systems, industrial monitoring (gas leak and pollution monitoring), wearables for personal air quality tracking, and anomaly detection in emergency scenarios. We have seen other ESP32-based environmental sensor platforms such as the Sensy32 board, MoreSense MS-06, and AirGradient One, but the […]

The Deauther Watch V4S IR is a Wi-Fi hacker watch that can run up to 21 scripts via IR remote for wireless and HID attacks

DSTIKE Deauther Watch V4S IR version

We previously wrote about the Deauther Watch X used for wireless pentesting. The company has now released the Deauther Watch V4S IR an Wi-Fi hacker watch with a built-in infrared (IR) remote control for executing several scripts stored on a microSD card. It supports deauther attacks, Bad USB (HID) attacks, WiFi packet monitoring, and real-time clock adjustments. The new version features a 1,000mAh battery that can be charged via USB and it comes with includes a Type-C power cable, acrylic cover, and software manual. You can modify the Ducky Script inside the text files but must keep the filenames unchanged for proper operation. These features make this tool useful for cybersecurity professionals and enthusiasts for network security testing, penetration testing, and more. Deauther Watch V4S IR specifications: MCU – ESP8266 WiFi SoC @ up to 160 MHz with 160KB SRAM, 4MB SPI flash Storage – MicroSD card (preloaded with 21 […]

Tobor open-source, modular robotic arm features two ESP32 modules (Crowdfunding)

Tobor robotics platform with pen plotter toolhead

Tobor (robot spelled in reverse) is a modular and open-source robotic arm platform powered by the ESP32-WROVER-I and ESP32-WROOM-32 (FluidNC CNC Controller core) modules. It is described as a “fully-featured robotic system that can fit on your desktop and is capable of helping you automate your workflow.” Tobor is billed as a customizable assistant for complex tasks such as assembly line help, CNC design, and rapid prototyping. The Tobor ecosystem includes several open-source components, including robotic arms, motion platforms, sensors, and actuators, that can be combined to create a unique system for “almost any desktop automation.” The Tobor Robot Arm supports multiple toolhead options such as the pen plotter toolhead, z-stage toolhead with 4th axis and suction cup, and the pick and place expansion pack. We have seen other open-source robotic platforms such as the SO-ARM100 AI robotic arm kit, CYOBot v2, and MIKRIK V2 Robot Car. Tobor Robot Arm […]

HackCable ESP32 and RP2040 Keystroke Injection

HackCable is a wireless-enabled USB-C keystroke injection cable described as the “ultimate tool for cybersecurity enthusiasts and ethical hackers.” powered by the ESP32-S3 or the Raspberry Pi RP2040. The ESP32-S3 version is described as the Wi-Fi Version and offers a built-in Wi-Fi hotspot, remote operation, and master-slave configuration for multiple cables. The Normal Version is a cheaper variant powered by the Raspberry Pi RP2040 microcontroller and built for focused, offline tasks where wireless control isn’t needed. The HackCable promises hardware keylogging, remote control, and master-slave synchronization for multiple cables. We have covered other USB penetration testing tools like the Diabolic Drive and Pendrive S3, but those were USB dongles while the HackCable looks like a standard USB Type-A to USB Type-C cable. There is very little information about the product, other than the microcontrollers that power it. It is likely running SuperWiFiDuck or some other USB rubber ducky program. It […]
