As always, the part numbers for the components are linked to websites for data and more information when available. I haven’t tested the maximum limit though. Replace these wires with the wires you removed from a sound blaster audio cable. Thanks for signing up. Earthmate II Pin Outs. The serial connection in the schematic is set up for a computer connection. There should be no pin 9 on the female side of this connector bridge!

MAKE, popular science, hackaday, engadget, fallon, braincraft Notice the battery plug in the lower left and the 5 wires just to the right along the bottom edge.


Unsolder the wire on solder pad 4 RED from the tripMate circuit board and insulate the exposed end. Read on to find out more information about the project, see the schematic and soure code I wrote, and find out how the data was visualized.

I have very little electronics capabilities but if this were available in easy to follow steps to modify the gps receiver, and then to add a simple 3 and a half digit LCD display it would be really great. You will also be receiving the weekly Make: I know it was nearly a year ago you asked this question.
