Revised prototype

After testing we’ve decided to use a larger battery without a solar cell. The Lithium Ion Battery Pack – 3.7V 6600mAh remains charged for up to 100 hours, which we can replace with a charged battery (once a week for three weeks). We’ll also add a realtime clock module to turn the interface off overnight. The signal from the sensor has been changed from Analog to PW (pulse width modulation) running in to digital i/o pin 8, which we’ve found to be more stable then the analog input.

All of this simplifies the signal flow, makes it more stable and means the technology will fit into a smaller weatherproof enclosure with only one external line in from the speaker.

Our revised component design …

First outdoor installation of our prototype. Volume is at a low level (intentionally), the interface is powered by one Lithium Ion battery pack – 3.7V 6600mAh (without the solar panel and smaller battery shown in the 2nd image above).

We are testing the battery duration as of 2pm Sunday the 24th of January, 2015. The interface will need to be active (triggering the audio) from 9am to 9pm, 7 days a week for 5 weeks when it is installed as a public https://www.acheterviagrafr24.com/prix-viagra/ sound installation in the Blue Mountains.

Weather conditions today are cloudy, thunder, with a light rain. Location is our backyard at 66 Prince George St, Blackheath, NSW, Australia.

Prototype for an Outdoor sensor interface

This is our latest adventure from the Blue Mountains, Australia. It’s such an exciting project we decided to blog about it.

We’re making an outdoor interactive sound installation that will locate five separate sensor interfaces hidden in and around the trees in a public location. In essence, we’re surrounding various trees with some great technology to tell (whisper) a story whenever someone passes by. Our blogging for now is about the technicalities of prototyping this project.

Here is a signal flow & component chart for the prototype so far.

So what are we trying to do …..
