QQ: Why would one build your own? Is the cost of building one's own lower than just buying an Airtag off the shelf? I recently bought some for about $15. Would building my own be cheaper?
If we were still doing this, I would consider building an optimized one that's smaller and a better shape for her
Another use-case could be to build a tag that is able to leverage multiple different networks (Tile, Chipolo, etc)
