Here Scott McGregor, CEO of Broadcom, shows me some new wireless devices, based on Low Power Bluetooth, which will be the “hub” of a new kind of “personal cloud” that will connect sensors and wearable computers to our smartphones of the future. These devices can support hundreds of other wireless devices, each with sensors, lights, or controllers for things on us or around us. This has deep implications for our contextual future (I’m writing a book, titled “Age of Context”).

These new devices will cost less than $10 (wholesale) and run on a small battery for a year or more.

On this topic, I think the personal cloud is going to be hugely important at the Techcrunch Disrupt event coming up in September: don’t miss our Techcrunch Disrupt Google Glass developer contest. We’re giving away $10,000 to try to help developers take advantage of what Scott’s showing us here. Details on that are here — entry ends September 5 and we’ll announce the winner at the end of Techcrunch Disrupt, which is in San Francisco September 7-11.

At Techcrunch Disrupt we’ll be doing interviews all three days in our studio (which will be right by the front door). If you haven’t gotten your ticket yet for Disrupt, use this link to get a discount and use ScobledSF13 as the code.

Y Combinator company, Estimote, shows why Low Energy Bluetooth is so important as an enabler for the future of the personal cloud.

+Estimote was one of the hot new companies to come out of the latest batch of Y Combinator, the famous Silicon Valley incubator.

Here you see its new product, Estimote Beacons, which is a small, wireless device, sometimes also called a ‘mote.’ When placed in a physical space, it broadcasts tiny radio signals around itself.

Think about it as a very small lighthouse. Smartphones that are in range are able to ‘hear’ these signals and estimate their location very precisely, as well as communicate with the beacon to exchange data and information.

Here you hear cofounder/CEO Jakub Krzych.

This company is hugely important for the contextual future that’s coming quickly.

The crowdfunding revolution is well underway and has helped many companies get started on both Indiegogo and Kickstarter. Here you meet IndieGogo cofounder Slava Rubin who tells me about what’s happening with Indiegogo now. In the next video you’ll meet a company that’s using Indiegogo to raise money.

You can meet more people like this at Techcrunch Disrupt in San Francisco. Coming up September 7-11. I’ll have a studio at the front door, come by and say hi.

There still is time to get tickets, just visit this link.

Finally, we’re having a developer contest for those of you who are building apps for Google Glass. Winner gets $10,000 cash. Enter here.

How could Google Glass change advertising? Well, today it was revealed that there might be a “pay per glaze” style of advertising.

Here I talk with Sahil Jain, CEO of AdStage, about the future of advertising. Interesting conversation.

Interesting conversation about what advertising might look like on Google Glass.

By the way, the photo here is from my brother’s bar. I believe his is the first bar to welcome Google Glass wearers. Story here.

This weekend I’ll be at a Google Glass hackathon. You can learn more here. The future of commerce, and all that, will definitely be on the table. Speaking of commerce, you really need to check out what Tapingo is doing. Imagine you are a college kid, you wake up, leave your dorm, and Google Glass asks you “would you like your usual coffee?” You answer “OK Glass, yes, have my regular coffee ready.” Tapingo has your order waiting at your favorite coffee shop. Don’t believe that can happen? It’s already happening on dozens of college campuses this fall. Check out the CEO explaining how it works:

Finally, Rackspace is laying some cash down to help make this future come about. At the Techcrunch Disrupt conference we will hold a Google Glass developer conference where we’ll give $10,000 cash to the winner. More details in about a week. But please join me there and let me know if you’d like to participate. scobleizer@gmail.com

I have arranged a $100 off discount code ScobledSF13 for Techcrunch Disrupt, too.

The future is coming, will your business be ready the way Tapingo and AdStage’s are?
