Small Remote Design Ideas

After a deep dive on DIY Arduino remotes, I’m imagining whats possible. I’ve seen little finger ring remotes for other devices, maybe not big enough for sk8 remote electronics, but I can imagine something, a housing, attached to the back of my glove…IDK just wondering if anyone else has a desire for a smaller or more wearable remote design. I know the actual throttle mechanism would have to be reliable and substantial to be safe. BT a no go from what I understand.

Anyways, just a thought, thanks fellas
