Since this is the topic of the day, we’ll be looking at how to purchase an item from DigiKey with tariffs in mind. DigiKey is a free trade zone, which means that if you’re not in the USA, you will not have to pay additional tariffs on goods that are re-exported. However, for USA destinations, the new tariffs can add a significant cost if the component has its last manufacturing step in China.

Let’s use the example of a simple I2C-controlled temperature sensor to see how our sourcing decisions may be impacted by tariffs.

You can build a tap-to-play video player using a Raspberry Pi 5, Adafruit’s NFC Breakout and NFC cards. Full Tutorial: https://learn.adafruit.com/nfc-raspberry-pi-media-player

To play a movie, just tap an NFC card over the 3D printed case. A python script runs code that launches movies in the VLC media player.

The NFC cards are fitted inside a 3D printed case inspired by VHS cassette tapes.

This project aims to make the movie watching experience more special by creating a physical experience. No streaming networks or wifi necessary!

Full tutorial: https://learn.adafruit.com/chinese-dragon-puppet-with-motion-reactive-flame-effect/overview

Make a Chinese Dragon puppet with a dramatic flame LED effect. The lights are motion-reactive so he lights up when you shake him. This project uses an Adafruit Circuit Playground Express with a built-in motion sensor and NeoPixel LED lights. The code is written in Microsoft MakeCode, an easy-to-use drag and drop code editor. (Or maybe in this case, a dragon-drop code editor.)

This is an easy beginner-level project that involves a little bit of soldering. You can download our code sample, or learn to make your own flame effects. This is a fantastic project to do with kids.
