OrBlink Kit An USB RGB LED Orb
The OrBlink is another nice creation. An open source USB controlled RGB LED inside a small plastic orb.
Supplied as a kit with everything you need, it requires some easy through hole soldering. With only 10 components it's a great way to learn soldering and end up with a fun useful product at the end.
Based on the Atmel ATTiny85 running code based on V-USB, the kit comes with a preprogrammed chip with the latest firmware. All you need to do is put it together, plug it in and go.
As the OrBlink identifies itself as an HID device there are no drivers needed for all major operating systems (Linux/Mac/Windows). There are loads of great uses for an USB connected RGB LED, use it to notify you of email INBOX levels, whether your computer (or server farm) is healthy or using maximum CPU, weather, home automation, the list goes on. Use one so your kids know when they are allowed to get out of bed in the morning!
There are a few other very similar products around created recently all based on the same basic hardware and principle, most of them are based on the same source code too. We think ours is neat since we made it of course, and it comes in a neat little Orb which looks great sitting on a table.
