Meet the Pulsar: wireless LED lights you can use for wearables and other projects. You can control brightness and color of its LEDs from your computer or any mobile device. The Pulsar has a rechargeable battery and a tiny microcontroller with Bluetooth. It can be used to build a fancy night light or complete your Iron Man suit.
The above video shows what the Pulsar is all about. The project is getting funded on Kickstarter.
