A set of Charmware embeddable circuit boards that hold a short push/pull MicroSD card socket, intended as jewelry components.

As a professional media creator, I use MicroSD cards to quickly offload large video files off my phone, while keeping an archive handy for future videos. To that end, I always carry a MicroSD-USB adapter, which is plugged into a Lightning adapter, which plugs into my iPhone. (In the past couple of years, my iDevices seem to have stopped being able to power a simple USB flash drive??)

(See: my mobile media setup [WIP])

…So anyway, this series allows me to stash those data cards inside jewelry. Because it’s cool. 🤩

Besides soldering on the socket, you can attach it to this PCB – or to any other piece of flat jewelry – with servo tape, or other super-sticky double-sided tape. That’s how I made the first prototype, and I continue to use this method sometimes; it’s so rugged that one can rip the card socket apart before the tape will detach.

Design notes thread (Mastodon)

This board’s visual design was inspired by the concept of wonder, or adventure – as represented in my “Aeiu Society” personal philoso-cult thingy from 2013+.

The hex symbol for adventure/wonder is based on the top of Sutro Tower, and since I designed this version for an event that took place in San Francisco, it felt right to add the tower as a nod to that personal lore. (Plus our local meteorological celebrity, Karl the Fog – because who doesn’t love some foggy swirls??)
