The blink(1) is a small USB LED status light that plugs into your PC, Mac, Linux or even Raspberry Pi device and can be set up to flash a certain color and pattern when something happens that you need to know about. That “something” is entirely up to you. For example:
Do you want to know if a friend has signed onto Skype, but don’t want a window popping up every time anyone has logged on? Do you want to be notified when a long download has finished? Do you want to know the snow conditions at Tahoe without checking every hour? Do you want to make a “busy” light for your office that glows red when your calendar says you’re in a meeting?
You can assign multiple alerts to one blink(1) and have each alert show a different color, pattern and brightness. You can also connect multiple blink(1)s to the same computer. The alerts are setup using easy-to-use open source Mac & Windows GUI application that connects the blink(1) to IFTTT, your mail, URLs or your scripts.
You can buy one blink(1) for $30 and larger quantities for a discount. Visit blink(1) for more info.
