This arc reactor inspired wearable won’t quite power an Iron Man suit, but it could come in handy. The ARC_platform can connect and coordinate multiple wearable devices, and it looks pretty neat to boot. Here’s more from via instructables:
Connections between the hub and other modules are made using male-to-male TRS audio cables (like shown in the picture above), the ARC_platform introduces a new standard way of using these connectors to ensure compatibility between modules. This standard is as follows: the sleeve of the connector will be used for ground, the tip for power and the ring will be connected to a pin on a microcontroller.
Instead of sewing the tech into a single shirt, the ARC hub uses a magnetic mountthat attaches through fabric. That means any shirt (or anything really) can become an “ARC shirt” — just snap it on, and you’re ready to go. This small change makes the hub vastly more versatile, wearable, and reusable in everyday life.
