Stacy DeRuiter's How To Make Almost Anything Blog - Week Four

Octber 11, 2005

This week's assignment is to work on planning for our final projects. I am hoping to make an acoustic and position-sensing archival tag for harbor porpoises. You can go back to see the little video I made of this device in action on my Week One page. What I know so far is that the tag will have to have various components:

I have a lot of work to do!

Here is a reworked and expanded version of the list of desirable tag components I made a week ago:

I STILL have a lot of work to do! To begin, I have realized that the list above is a very tall order and would take way more than a few months' work to build, especially by someone as inexperienced as myself. I have decided to prioritize the list and start working on a simplified version of the tag, with hopes that adding additional sensors and features will eventually get easier once I have a simple version of the tag created. For my class project, I am going to lower my expectations a bit and try to build a little device that: If I can do that in record time, I will proceed to adding:
  1. gyroscopes
  2. pressure sensor
  3. VHF radio beacon
  4. audio capability (hydrophone)
  5. dsp and signal processing capability
  6. all the rest
Here's a ridiculously simple sketch of what I am trying to do... Now I should stop writing HTML and start poring over my big pile of electrical engineering library books...
