WISP adds wifi to the Internet of things

The guys over at embdSocial sent in a project they’ve been working on for a while. It’s a small wifi module for an Arduino or other microcontroller called Wisp. Unlike the many, many other wifi breakout boards we’ve seen, the Wisp has a truly incredible amount of potential. With an API that allows an Arduino to post to Twitter, sending text messages, and even has remote admin¬†capabilities, the embedSocial team came up with something really cool.

We’ve seen our fair share of projects that use wifi, but the Wisp is amazingly clever as to how projects can be controlled. Each Wisp is administered through the Internet. Once a Wisp is registered to your online embdSocial account you can upload new code without ever physically connecting a microcontroller to your computer.

To demonstrate the remote administration capabilities of the Wisp, the embdSocial guys put an Arduino and Wisp inside an electrical junction box. With their setup, the guys have the simplest and smallest Internet connected power outlet we’ve ever seen.

After the break, you can see a demo of a Wisp opening a garage door and a remotely operated, web enabled airsoft turret. We’re loving that the turret sends video from the gun to any device on the Internet, and it’s impressive that [Chris] and [Art] whipped up both these projects in a single weekend. There’s also a Kickstarter for the Wisp, so here’s to hoping we can pick one of these up soon.

Notacon 2008: Last-mile wireless


[Mark Doner] presented on how the WISP he works for near Toledo is set up. His most important point was that 802.11 is garbage when it comes to the type of installations WISPs do. 802.11 expects the clients to adjust based on the traffic from other clients, but when all your clients are directional they won’t see each other. Mark uses Motorola’s Canopy equipment, but he also mentioned Trango and Redline as other vendors. The radios operate in the 5.7GHz band which doesn’t have any power restrictions so they can use refurbished Dish Network dishes when they’re doing long shots. For customers that are nearly at the edge of service, they have 900MHz equipment as well. Heavy fog and freezing rain have proven to be the only weather that really affects the service. For back-haul between their towers they use Dragonwave equipment. Each of the radios costs ~$350 and features GPS to determine distance and maintain sync with the AP. It was interesting to see how a good WISP operates as opposed to the flakey ones we’ve had to deal with in the past.
