As part of my studies at the Wiki Creek field station, I've become interested in longitudinal photographic surveys. I've now created a device to facilitate consistent panoramic captures based on permanent mounting of a monopod base.
I describe the work on the Wiki Creek site:
I will bring the engineering prototype to the DorkBot meeting tonight. I'm calling it the "WikiPod". (The name has worked well for me before.)
After a year of occasional fiddling I am finally happy with the stability and convenience of my sensor network. Some features include:
For your browsing pleasure I offer my latest sensor addition, simple ac line voltage monitoring, or browse my whole network.
I've added a CdS photocell to my network of home temperature sensors. I'm reading it as an analog input using the WebServer Arduino code that goes with the Ethernet shield.
I'm calling this a Twilight Sensor because the sensor range I happened to choose covers that half-light of mornings and evenings. I've cooked up a special FLOT graph that traces equi-temporal contours from day to day.
If you study this long enough you will see that, yes, the days are getting longer.
My friend Wayne Downer gave me a couple of 1-Wire digital thermometers which I've now hooked up and supplemented with a few more of my own. You and I can both watch the temperatures drop at my house this week using the cool graphics I cooked up with jquery.
You'll find the live data here:
I found the SECODER that I spoke about last meeting. It was in the bottom of the wrong junk box with old antenna equipment, not old telephone equipment. My mechanically inclined friends helped me get it working again.
I've written a web page describing my original application, Dial-a-Door.
I got out the x-acto knife and built a display stand just for tonight's meeting. This got featured on the AboutUs blog.
I thought about including an Arduino in the setup to provide an automated demo. I'm glad I didn't. I've been told that the computer would destroy the steam punk style of the whole setup.
