Wired Rings

⚠️ Warnings & Instructions

• While stretchy these rings might not fit you if you have large fingers. If so consider modifying the STL.

🚀Specifications

Device

Parts

• 0510 axial inductor: 1 mH | 5.9 measured Ohms | Source example
• 0.28 or 0.25 mm enameled copper wire
• 3D printed ring
• Optional connector

Tools

• Soldering iron
• 3D printer

Assembly

• Print one of the files, vertical or horizontal: here. They can be printed in PLA with no supports or in resin. The small holes for the inductor leads can be difficult to print right. Use a hot needle or a wire to clear them out if necessary.

• Start by pre-bending and cutting the inductor leads. Then slot the inductor into the ring as per the images below:

• Solder a length of wire to each of the inductor leads. Remember to clean the enamel off and be careful not to melt the plastic ring.

• Optionally solder a connector to the wires.

**You're done **🎉 Now plug it in and try it!

🩺FAQ

• Will they fit me? They are designed with a slot to be semi-flexible. In addition, they are printed out of PLA which can be softened up with heat to stretch them a bit. So they should fit most fingertips.

• How much power can be run through them? See the rated watts for the inductor and the wire you chose. Alternatively, raise the power until the inductor feels warm.

• How strong is it? It depends on the signal you feed it. In audio terms this is just a speaker, the loudness depends on your amplifier. For reference, these use the same inductor as the PICOs but the PICOs are not amplified whatsoever and do not push out much power to it.

• Does it make a sound? Nope. If you stick your finger in your ear and get it close you can use your finger as a headphone though. Fun party trick.

• Is one design better (vertical vs horizontal)? If there is a difference it is very small and depends on your magnet's orientation and how you wear it. Overall, not really.

• Should I make it myself? If you have the tools then sure, you can find the parts online.
