LED Usage Examples:
1. Card
2. Accessories
3. Accessories (USB powered)
Anyway, insights from looking at the photos:
The ideas and technology are good, but honestly I'm not sure how necessary or useful they are in daily life. If we added a bit more substance...
Case 1) A function that displays the remaining balance or number of uses on a transit card or other card.
Case 2) Could be used extensively at concerts and events. Simply emitting light is fine, but it would be even better if it responded to sound and temperature.
- For musicians who are deaf, if we define specific colors and brightness in response to sound tone and volume, it could be very socially beneficial.
- If we could continuously accumulate and collect such data, we could hope for smoother exchanges with people of different physical conditions, like sign language.
Case 3) The concept of making USB-powered lights is something I've seen on YouTube.
