HackBat – DIY open-source hardware Flipper Zero alternative features Raspberry Pi RP2040 MCU, ESP8266 WiFi module, RF transceiver…

HackBat DIY open source pentesting device

HackBat is an open-source hardware pen-testing device designed for hackers and makers and equipped with a Raspberry Pi RP2040 microcontroller, an ESP8266 WiFi module, a sub-GHz RF transceiver, NFC, an OLED display, and more… It’s basically a DIY alternative to the popular Flipper Zero wireless hacking tool, that you can produce and assemble yourself. The Flipper Zero was the victim of its own success with the Canadian government (wrongly) claiming it could easily be used for car theft and planning to ban it (status still unclear right now),  so Flipper Zero alternatives such as the M1 multitool device got some traction as backup solutions with some extra features. But any closed-source device could eventually be banned, something that’s close to impossible for an open-source hardware device like the HackBat although policymakers could still decide to impose heavy fines if they wanted to make this type of device illegal… HackBat key […]

Easily build a robot car with the Car Base Board for the STM32F411 “Black Pill” board

Car Base Board Mounted PCB chassis

The Car Base Board from Applying Microcontroller Solutions is a modular platform for building robot car projects powered by the WeAct Studio Black Pill development board. The Black Pill board is an upgrade to the “Blue Pill 2” board and features the STM32F411CEU6 microcontroller running at 100MHz with 512 KB of flash memory, 128 KB SRAM, and a USB Type-C port for power and programming. The Care Base Board printed circuit board is a base controller that takes hardware expansions such as wireless modules, servos, and sensors to monitor and control a robot car. The onboard headers provide a straightforward way to wire these connections and help prevent a tangled mess (rat’s nest) of wires. The PCB’s design makes it easy to use widely-available, “generic” devices and boards in development and to power all of them with batteries. It also allows the developer to select their favorite wireless communication device. […]

ardEEG shield works with Arduino UNO R4 WiFi for biosignals measurement

ardEEG Shield Arduino UNO R4

PiEEG has launched the ardEEG shield specially designed for the Arduino UNO R4 WiFi and capable of measuring biosignals such as those used in electroencephalography (EEG), electromyography (EMG), and electrocardiography (ECG). PiEEG, led by Ildar Rakhmatulin, Research Associate at Heriot-Watt University in Edinburgh, launched the PiEEG shield for Raspberry Pi to enable brain-computer interfaces last year, and now the company has been working on the equivalent design for Arduino with the ardEEG shield equipped with eight channel taking input from wet or dry electrodes. ardEEG shield key features and specifications ADC – Texas Instruments ADS1299 Analog-to-Digital Converter for biopotential measurements Supported board – Arduino UNO R4 WiFi 8 channels for connecting wet or dry electrodes (Electrodes are positioned according to the International 10-20 system) Host interface – Arduino headers with SPI used for data transfer with a frequency from 250 SPS to 16 kSPS and a resolution of 24 bits […]

Arduino Alvik is a 3-wheel robot designed for STEAM education

Arduino Alvik

Arduino Education’s Arduino Alvik is a 3-wheel educational robot that was initially unveiled at the Bett 2024 show in London and designed to teach robotics, programming, and other STEAM subjects. The robot is based on an Arduino Nano ESP32 board and comes with a set of nineteen lessons designed by Arduino Education’s team in collaboration with teachers so that students can learn the basics of IoT, get started with MicroPython, and get themselves familiar with various physics and engineering concepts. The company has yet to provide the full specifications for the Alvik robot, but here’s what we know at this stage: Mainboard – Arduino Nano ESP32 2x wheels plus 1x ball wheel Sensors – “High-quality sensors” that include a ToF ranging sensor, line-following sensors, a 6-axis accelerometer & gyroscope, a proximity sensor, and color sensors. Expansion 2x Grove I2C connectors 2x Qwiic connectors 6-pin servo motor header for up to […]

Arduino Pro Opta D1608E/D1608S expansions feature electromechanical or solid-state relays, 16 I/Os

Arduino Pro Opta Ext D1608S and D1608E

Arduino has recently announced two new expansions to their Arduino Pro Opta PLC series – the Arduino Pro Opta Ext D1608E and Arduino Pro Opta Ext D1608S, the main difference between the two is that the D1608E features 8 electromechanical relays (EMRs) whereas the D1608S features solid-state relays (SSRs). Other than that both expansion modules have 16x programmable I/Os (0-24 V digital / 0-24 V analog) which doubles the number of I/Os we have seen on the Opta micro PLC. Both are compatible with the Arduino IDE and the PLC IDE and are easy to install on a DIN rail. These features make it suitable for control, monitoring, and predictive maintenance applications. Previously we have seen Arduino launch a PLC Starter Kit for those who want to get started with PLCs. Additionally, we have written about ESP32-powered PLCs, Raspberry Pi-powered PLCs, and more. Feel free to check those out if you […]
