Laser audio

Today I built a laser pen solar panel audio transmitter thing – using these two sets of instructions – for the most part:

It works great, but I should have used a battery case instead of soldering the batteries together.

Built it into a Sparkfun box:

The next step is to experiment with filters – like an aquarium for example.

ep-4xx13 DSP – week 14

Internet of things (IoT)

Big Data http://www.zdnet.com/big-data-an-overview-7000020785/ is about finding patterns in data. The IoT http://en.wikipedia.org/wiki/Internet_of_Things  allows you to make your own patterns by combining data from many sources.

Examples

Observations

  • Moral implications of ubiquitous tracking
  • A field of opportunities – connect
  • Sonification
    • parameter mapping
    • earcons
    • alarms
