Introduction: Why Pressure Sensing Matters in Modern Domestic Appliances For most of its history, a domestic appliance did one job. A gas meter counted gas. A blood pressure monitor inflated a cuff. A coffee machine pushed water through grounds. Today, those same devices are expected to connect to the cloud, respond to safety events in real time, operate for years on a single battery, and report data accurately enough for billing purposes. Pressure sensing is central to all o

The Accidental Hacking of 7,000 Robot Vacuums proves that manufacturers are still shipping IoT-enabled products with serious security vulnerabilities Sammy Azdoufal just wanted to steer his new DJI Romo robot vacuum with a video game controller. While building his own remote-control app with the help of an AI coding assistant, he reverse-engineered how the vacuum communicated with DJI's cloud servers in order to extract an authentication token. That token, it turned out, work

Introduction – Why Battery Life Has Become the Most Critical Constraint in BLE Design There is a contradiction at the heart of the IoT market. Bluetooth Low Energy devices are sold on the promise of long, largely maintenance-free operation. Yet for many product teams, battery life remains the single most persistent source of post-launch complaints, costly returns, and unplanned field maintenance. A smart sensor that needs a battery swap every eight months rather than every tw

Introduction – Why Connector Selection Matters More Than Ever in Embedded Design For a discipline that often receives less attention than the silicon it connects, connector selection has a disproportionate impact on embedded system reliability. A connector that fails under vibration, degrades signal integrity at high speed, or introduces moisture ingress will undermine the performance of every component around it. Yet the range of connector types, standards, and mechanical co

Introduction – The Small Speaker Problem Has Never Really Been Solved Every engineer who has worked on a compact audio product knows the feeling. The mechanical design team has determined that the speaker driver must fit within a 45mm diameter and 8mm depth. The industrial design team has decided the enclosure is 12mm thick. And the product brief still requires the device to sound impressive. This is the small speaker problem, and it shows up across a surprisingly wide range

Why Display-Native MCU Architecture Matters in Industrial Design Most microcontroller suppliers have a standard playbook: design a capable CPU core, bolt on peripherals (SPI, I2C, ADC), and sell it to everyone from automotive to IoT. Display functionality, if it exists at all, is an afterthought -a controller bolted onto the side of the main processor, consuming extra silicon, complicating firmware, and burning unnecessary power. Epson took a different approach. For 25+ years
