Interface


Home Up Voltmeter Interface 2012

 

 

A rig to computer sound card interface project. 

One idea is to use an Elmer project to drum up some Club hamfest sales buck.

 

The circuit: See the circuit with isolation transformers  file 

 

With a well stocked junk box 

(for cables, enclosure, misc hardware).

This is still not complete.  

bulletTwo (2) D-9pin cables need to be added. 
bulletMiscellaneous hardware (screws, grommets, etc) 

Compare this build cost (no profit)  to Retail for a West Mountain Nomic at $59.95.  

I'd buy the new complete Nomic.  Not a good Hamfest club sales project.
