Probably, he's going to need a little more detail on the selection of diodes, if he's going to get it to work that way. Doing it wrong, will produce a $200...
I have created a Map Comparison page on my website: http://members.shaw.ca/davepatton/mapcompare.html By using the same area, and providing screen captures, it...
Well, I am looking at a standard schematic for USB ports and pin 1 VCC (5 volts DC) comes from the computer power supply. There is nothing between it and the...
Tom I believe you are essentially correct and have no intention of being involved (again) in any technical theory here. I will only state facts based purely on...
Dave Thanks for the comparisons. The Spectrum product is impressive, almost as good as ours (-: Can I presume the grids are UTM on the maps, spaced 1Km at...
... Yes, 1KM at 1:50,000 and 10KM at 1:250,000. I've received confirmation from one other map producer that they are sending me samples of their maps, and I'm ...
Thanks, that's a good comparison. Very useful. I would comment that on the GeoGratis Landsat 7 Band 8 satellite image, it would look much better with some...
I looked up one of the popular chips used in PCI to USB 83C572. One of the signals on the chip is the ability to monitor for Overcurrent detection (pin 52 for...
... There is no such thing as a "standard schematic for USB ports". What you are looking at is just one of many possible implementations of a USB interface. ...

Is there a reason why the Image to OZF2 Conversion program takes so long to load. I am running a 2.5gHz PC and it seems to take the same amount of time to load...
Laurie FWIW The program takes c3.0 seconds to load on my PIII 1.0GHz PC, in an EMPTY folder. If you open the program and the default folder (source image ...
