After seeing a thread about the LM3914 bar/graph display and planing on etching a couple of boards I remembered that I still have a bunch of parts for the EQ / spectrum analizer unit I and a boy scout were designing .
Well to make a long story short, The scout is going to away to ISU come September.
I have decided to etch the boards for this project. But before I do I copied and pasted an abreviated schematic together (right channel, one frequency)
most if not all of this schematic has been reviewed by Audioguru etc. but for my piece of mind I hope I can get a quick review before I finalize the PCboard layouts.
THANKS!!
most of the lines are straight. Tried importing into PAINT but way to much erasing etc. unless there is an easier way??
