The project initially started as a simple idea of "how low a cost can I create a usable SlimeVR tracker for?" but eventually turned into an extreme challenge of fitting all components into the smallest possible space. Although this tracker does not use the most advanced high-end hardware, the cost of a single tracker is only about 7-8 US dollars, and the total price of the entire set of equipment is only about 72 US dollarsThe DocsIt can be found in the middle.
