This tutorial demonstrates how to make a silver ring that holds a glass RFID tag. It’s the same kind folks get implanted in their hands to unlock things like door, computers, or vehicles. I’m not quite brave enough to get the implant but I do like making jewelry and wearing rings, so this solution is perfect for me.
It’s time for another excerpt from my free Instructables jewelry class ! Learn to make these easy wire wrapped and beaded earrings , now with a video describing the process.
Build yourself a buzzing bracelet for subtle haptic feedback as time passes! It’s great for reminding yourself to get up and walk away from your desk for a few minutes each hour, or just as a way to have a new awareness of how the perception of passing time varies based on what you’re doing.
You’ll whip up a vibrating motor circuit using a transistor, resistor, and diode, and use GEMMA to control the frequency of vibration in between low-power microcontroller naps. The circuit lives inside a linked leather/rubber bracelet, but you could build it into whatever you please. This project involves some precision soldering, but is otherwise quite easy!
Before you begin, make sure you’ve read the following prerequisite guides:
