DHCP, Parallax Stingray, Dust Bunnies and the Xbee ASP DotNetNukes Discovery

Wow! That’s a mouth full! “How will he tie all that together?” A couple nights ago I lost internet connectivity at the beginning of what I thought would be an all nighter of coding. When I woke up the next morning I had a new DHCP assigned ip address from Comcast my internet service provider. Since early spring last year I have been evaluating CMS, Blog and wiki software and reacquiring  my system administration skills as well as learning some new computer programming languages and other sundry and various nick nacks of nerdom. I had a couple different sites up at home testing various platforms from www.drupal.org, www.wordpress.org, www.dokuwiki.org, www.mediawiki.org and others. Ohh yea, and Ruby on Rails which is so cool I’m getting shivers just writing Ruby on Rails. You may infer correctly that I’m interested in open source projects. With the ip address change, it looks like Comcast was rearranging subnets, I had to reconfigure DNS hosted at godaddy to point to the new ip address to continue to serve those eXperiments in my basement on a Fedora Linux system. This blog, www.rodaw.com, was hosted there in the basement of my home. Now I’ve moved it to a hosting account at www.godaddy.com. You can read about that experience here. Late note, in between beginning and finishing this story I not only moved the site from my basement to godaddy, but then from godaddy to vps.net where it lives now on a virtual machine.  The positive spin I’ll say about the DHCP ip address change is that it motivated me to move www.rodaw.com. I had not wanted to advertise the sight much while it was at home. The legalities, bandwidth, the possibility of ip reassignment and exposing my home network to so much attention. So way cool! I’ve moved rodaw and feel more comfortable letting it loose. OK that covers the DHCP, now the www.parallax.com Stingray robot, the dust bunnies and the xbee .asp .net discovery of www.dotnukes.com which ties into the C# class I’m taking at www.scc.spokane.edu which well it just wouldn’t fit in the title of this blog. So UPS dropped of my package from Parallax. They didn’t knock on the...

Outboard Motor Auto Pilot

I would like to make an auto pilot for my boat. This is a wide shot of the stern to get a general overall feeling for the space involved. Stern view. This is a detail of the interface of the steering control arm and the Mercury 85hp motor. Detail view of the stern. Note where the control arm meets the meets the control horn on the motor.           Question: What might I use for the actuator. I’d like to stay away from hydraulics on this small of a project.   Notice the bolt (left picture) at the center that connects the motor to the steering control arm. Here is a detail showing there is enough room to perhaps get another thingie of some sort attached. Plenty of room to change bolts (right picture) to allow some bracket to hold the house for the thingie! So what might we use for a thingie? Worm drive? Mega stepper?...
