Hello, just thought I'd let you know that you need to add a few more details to your project to give it the best chance of going through to the next round of The Hackaday Prize.

By August 20th you must have the following:
- A video. It should be less than 2 minutes long describing your project. Put it on YouTube (or Youku), and add a link to it on your project page. This is done by editing your project (edit link is at the top of your project page) and adding it as an "External Link"
- At least 4 Project Logs
- A system design document
- Links to code repositories, and remember to mention any licenses or permissions needed for your project. For example, if you are using software libraries you need to document that information.

You should also try to highlight how your project is 'Connected' and 'Open' in the details and video.

There are a couple of tutorial video's with more info here:

Good luck!

Think you could fit a dozen temperature/humidity sensors inside of ping pong balls and have data transmit within about 3 feet, then display on a web interface?

I guess that is possible but not with these sensors. The DHT11 requires a signal from the Arduino and, at some point, there is a two way communication. I think a sensor with embedded bluetooth capabilities is what you need but I am not aware of any at this point. Please also notice that if the sensor is inside the ball, the accuracy of the measures will be affected.

  Are you sure? yes | no
