When building a smart home, choosing between Zigbee, Z-Wave, and WiFi is one of the most important decisions you’ll make. Each wireless protocol serves a different purpose—Z-Wave offers reliable, low-interference communication for security devices, Zigbee excels in large networks of low-power sensors and smart lighting, and WiFi provides high-speed connectivity for cameras and streaming devices. Understanding how these technologies differ helps you create a smart home that is faster, more reliable, and better suited to your automation needs.

For over a decade, the Raspberry Pi has been a favorite tool for hobbyists, students, and makers—powering everything from coding lessons to retro gaming consoles. But in recent years, the Pi has stepped into a new arena: industrial prototyping and edge computing.

If you work in electronics manufacturing or hardware development, you’ve probably felt the pain of chip shortages over the last few years. Whether it was waiting months for an MCU, dealing with skyrocketing prices, or scrambling to redesign a PCB around an alternative part, supply chain issues have been a headache for everyone.

That’s where the CHIPS and Science Act comes in. Passed in 2022, this $52.7 billion investment is the U.S. government’s attempt to bring semiconductor production back home, making the industry more resilient and less dependent on overseas fabs.

But what does this mean for engineers, startups, and manufacturers? Is this just another government initiative with no real impact, or will it actually change how we build electronics in the U.S.? Let’s break it down.
