infineon PSOC 4100T Plus MCU

Infineon PSoC 4100T Plus is a new low-power Arm Cortex-M0+ MCU designed for battery-powered or low-power embedded systems that require advanced capacitive touch and proximity sensing. The microcontroller comes with 128 KB of flash, 32 KB of SRAM, and an 8 KB ROM. One of the most interesting features of this MCU is Infineon’s fifth-generation CapSense MSCLP technology, which enables high-resolution, low-power capacitive sensing even in deep sleep mode (as low as 8 µA). Its capacitive sensing uses both self and mutual capacitance methods, supported by analog front-end filtering, sigma-delta modulation, and digital filtering techniques, delivering a signal-to-noise ratio greater than 5:1 for accurate detection. The MCU supports gesture detection, human-machine interfaces (HMI), and smart sensing applications, making it ideal for wearables, consumer devices, and IoT systems. Additional features include a 12-bit 1-MSps SAR ADC, six TCPWM blocks, smart I/O with programmable logic functions, multiple UART/I2C/SPI interfaces, and up to […]

FlippenHeimer Geiger Counter module adds radiation sensing to Flipper Zero

FlipperHeimer Geiger Counter module

The FlippenHeimer is a compact Geiger counter add-on module designed to work with the Flipper Zero. It allows users to monitor beta and gamma radiation levels using the Flipper’s display and power source, making it a portable device to detect radiation. Built around a J305 Geiger–Müller tube, the FlippenHeimer provides real-time data logging, visual feedback via graphs.

PicoEMP – A Raspberry Pi Pico-based open-source electromagnetic fault injector designed for EMFI testing and research

ChipSHOUTER PicoEMP

The PicoEMP is a compact, low-cost, open-source electromagnetic fault injector (EMFI) tool developed by Colin O’Flynn for researchers, hobbyists, and educators interested in hardware security. Unlike NewAE’s professional-grade ChipSHOUTER, PicoEMP is a bare-bones device designed to be safe, usable, and most importantly, affordable. Built around the Raspberry Pi Pico, this device generates high-voltage pulses using a transformer circuit (originally for photographic flash charging) to discharge energy from a low-ESR ceramic capacitor into a custom-made coil tip, which creates an electromagnetic field capable of injecting a little bit of power to the internals of the processors such as registers and SRAM. This can be exploited to flip bits and test the robustness of embedded systems against such attacks. ChipSHOUTER-PicoEMP specifications Main controller – Raspberry Pi Pico (RP2040 dual-core Arm Cortex-M0+ MCU @ up to 133 MHz) Purpose – Electromagnetic Fault Injection (EMFI) for testing embedded systems security Components High-voltage pulse generator circuit […]
