Taking the GPS for a walk in the bush
Submitted by paulh on Thu, 2007-08-30 22:01.The next day I set out to map some of the roads and tracks around a patch of Bush that I have been frequenting for a few years - recording native Orchid growth etc.
Here is the voltage recordings of the battery:
11:30 13.25V (No load)
11:32 12.63V (PC On)
14:45 strong electrical burning smell noted!
14:50 9.8V (No Load)

Talking the GPS for a drive
Submitted by paulh on Tue, 2007-08-28 22:04.Ok, time to go for a walk and a drive...
I checked out my last lot of GPS code from the SWASC subversion repository and uploaded it to the MARK I mini-ITX PC. I then went for a walk around the park at the back of the house. The PC and GPS where running from a common 12V 7A Sealed Lead Acid (SLA), battery. The first walk lasted 1 hour 40 minutes. I noted the voltage drop over this period:
13:40 12.28V (on load)
14:00 12.14V
14:40 11.96V
15:00 11.88V
15:05 12.00V (no load)

Re-Mapping my GPS data
Submitted by parkviewadmin on Mon, 2007-08-13 00:21.Well, it's been a while, but the SWASC wheels (propeller?) are still turning.
This afternoon I have been discovering how to use a Freeware GIS mapping program called MapWindows. At the moment, it pretty well does all that I need a GIS program to do.

GPS Testing Project
Submitted by parkviewadmin on Mon, 2005-10-03 21:19.GPS Testing Project
Well, I have a GPS, and I have a new computer, so lets test this all out. This has been compiled from emails that went out to the swasc mailing list. I am trying this out in the Book page format to see how it looks.
