Why Technology Works !!

   Here I am standing beside my self in wonderment that so many of you out there in the real world take the precious time out of their busy day to look at my blog !!
   I review the stats and there are people from every part of the globe and this makes me very humble and happy !

   Now my lab and research area is in a shambles, not through any natural disaster. I work and read and things get a just more than a bit messy. I have failed in my initial experiments with ultrasonic range finding for my robot . The circuits I have painstakingly built have failed and I have nothing to show for it. So I have to do some more research. Now there are commercial units available however I want to build everything from scratch . It is more fun that way and you learn a great deal more as well.
   
   I have also been documenting my success with Sam's main board. I have implemented an input circuit and a functioning ram. I have also written a z80 machine language program that tests the hard ware. I had to do this before I go on so I can reference back when things go slow or nowhere at all. 
   
   I will provide more detail and schematics of my failed experiments in the next blog. I wonder if the people who write these books and draw up these circuits actually build and test them. In my experience I have found more than one mistake and this is annoying and very frustrating. My rule is to test and test and make sure the things I build and program, work always and for hours if not days. When you trust these guys you assume they know what they are writing about. MY RULE trust yourself when it comes to building things.
