SmartWings Smart Shade Review – An outdoor, solar-powered Matter shade tested with Apple HomeKit and Home Assistant

Recently, we received a custom-made-to-order smart shade from SmartWings for review. We never heard about SmartWings before, but the company claims to have been in the smart blind/shade and home automation industry for over 15 years. Their standout feature is the high degree of customisation they offer—whether it’s the type of shade, custom size up to almost 3 meters in width and height, various fabric styles, and compatibility with major Smart Home platforms like Amazon Alexa, Google Home, Apple HomeKit, Samsung SmartThings, Home Assistant, and Hubitat. SmartWings asked us to select a location in the house where we wanted to review the smart shade. We wanted to review a solar-powered outdoor shade, so we selected a windowed door with direct sunlight. We carefully measured the dimensions following the instructions on the company’s website to understand the process. We had to select the shade type, privacy level of the fabric (openness), […]

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

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 […]
