Traveling or on the road, sometimes finding an open network to get online and finish a job is more important than lunch or a nap. MASLOW (Mini Adafruit System Locates Open Wireless) is a tiny battery-powered WiFi detector with a 3D-printed enclosure…assemble one yourself and clip it to your laptop bag.

How does it work?

In this project, we’re making a portableWiFi hotspot finder using the Adafruit CC3000 and Pro Trinket micro-controller. The CC3000 is a WiFi breakout board that adds connectivity to your micro-controller projects.

5 total modes indicate the status. When the LED starts flickering fast, it’s scanning for WiFi networks. A slow blink indicates an open network is in range. 1 second blips mean closed networks only, and 4 second blips means no WiFi networks.
