Review on Yasorn Vibration Vibrating 12000RPM Electronic by Darryl Duncan

Now I'll get back to you, dear reader. I have no idea why I bought them. I didn't want faster delivery and when it got here, whatever project I had in mind, it was already there. Well, out of my head. But hey! A good master will always find a use for everything. And these little guys can come in handy. Most (if not all) varieties of ESP32 dev kits have pins designed for touch sensing. They are less precise than special boards, but are certainly suitable for everyday use. My humble project: Using a Forstner bit, drill a centimeter-sized hole in a piece of wood, leaving a small fraction of a millimeter at the very top. Solder the side of an object with the exact same size, shape, and chemistry as a pre-1980's coin to the development kit's resistor pins. Attach one of these vibrators to the back of the penny-like object using epoxy. Connect to a power source. And now you have a button that can be activated with a simple touch of your finger and that vibrates when activated. Haptic feedback is essential for touch devices. The only thing that bothers me: the wires are ridiculously thin. To the point where I could only expose the copper core with pliers and the strength of my teeth. But since I'm sure these things were designed for professional use rather than a casual maker, I don't think that's unreasonable. Each of the 15 units I purchased worked perfectly with my desktop power supply. I "broke" 2 of them by pulling the wires too hard, but I ended up soldering a stronger connection.
