How to Overengineer a Crib Mobile for a Newborn… and It Spins Like a CNC! 👶⚙️

-

 

What do you get when a new dad with an engineering obsession builds a baby mobile? 🤖 A stepper-motor-powered, Arduino-controlled, 3D-printed masterpiece that could probably launch satellites. Okay, maybe not — but it does rock the crib. In this project, Pavel Korshunov shows how he brought together a NEMA17 stepper motor, Arduino Nano, Fusion 360, carbon fiber rods, and pure dad energy to create the ultimate crib mobile. Is it overkill? Absolutely. Is it awesome? You bet. Perfect mix of DIY, IoT, and dad jokes. 💡👶 Tools & Materials:

  • NEMA17 steeper motor
  • TMC2209 Stepper motor driver
  • Noctua Premium Quiet Fan to keep driver cool
  • Arduino (Elegoo) UNO board during prototyping
  • Arduino NANO in a final product
  • Step-down DC/DC voltage converter to use 12 volt for motor and 5v for logic board
  • 608zz bearings
  • 8 mm Carbon Fiber tubes
  • 5/16" OD Vinyl-Flex PVC tubing
  • Creality Ender 3 3D printer

Miraikan: The Future Is Here

-

The National Museum of Emerging Science and Innovation, simply known as the Miraikan, is a museum created by Japan's Science and Technology Agency. It was opened in 2001. It is situated in a purpose-built building in the Odaiba District of Tokyo. In the video, I am visiting Miraikan, the National Museum of Emerging Science and Innovation in Tokyo, Japan. I explore various exhibits spread across multiple floors of the museum, focusing on emerging technologies and scientific innovations. The first floor introduces the museum, showing a ticket purchase and an overview of the building. I take an escalator to the next floor where I check descriptions of the different floors and their themes. I am excited about the exhibits and mention a gift shop. The second floor is described as a special floor not accessible to the public, while the third floor features a kids' zone and information stands. I explore the "Create Your Future" exhibit, which focuses on envisioning a prosper...

Zigbee vs. Z-Wave: Which Mesh Protocol Wins in Smart IoT?

-
Image
When it comes to building a reliable smart home or IoT network, Zigbee and Z-Wave are two names you can't avoid. Both offer mesh networking. Both prioritize low power consumption. Both promise simple device-to-device communication. But which one is better for your needs? Let's break it down clearly. 1. Frequency Band Zigbee: Operates mainly at 2.4 GHz (globally) but can use sub-GHz in some regions. Z-Wave: Works at sub-GHz frequencies (around 800-900 MHz depending on the region). Impact: Z-Wave’s lower frequency means less interference (since Wi-Fi and Bluetooth crowd 2.4 GHz). Zigbee's 2.4 GHz can face more noise but offers higher data rates. 2. Device Ecosystem Zigbee: Huge ecosystem. Brands like Philips Hue, Amazon Echo, and Samsung SmartThings rely on it. Z-Wave: Smaller, but highly curated ecosystem with strict interoperability standards. Impact: Zigbee offers more choices, but sometimes devices from different vendors don't play perfectly together. Z-Wave has...
