Smallest lower power LED light project Answered

I want to try to put two LED lights on my glasses, the idea would be to write some software to turn it on and of and notify about stuff usps tracking

I was wondering what would be the smallest project possible Is there any resource where people just induced a current to light a small led maybe? showbox

LEDs are like tiny lightbulbs. However, LEDs require a lot less power to light up by comparison. They're also more energy efficient, so they don't tend to get hot like conventional lightbulbs do (unless you're really pumping power into them). This makes them ideal for mobile devices and other low-power applications. Don't count them out of the high-power game, though. High-intensity LEDs have found their way into accent lighting, spotlights and even automotive headlights. You can buy one of them on walmart.

Inducing current over such large distances is quite difficult to do... Even more of it should be small for a pair of glasses.
My solution would be:

- Power the stuff on the glasses with rechargeable CR425 / CR435 / CR535
- Use a cheap and easy Superheterodyne sender-receiver-pair (433MHz)
- Sender = Arduino or Raspberry to connect to a PC or whatever...
- Receiver = Maybe even only a FET to conduct when a signal is received (AKA Binary-Signal-to-light-converter)
