Thanks by the data, Audioguru. I got the board etching done, but before go shopping I'm worried about this Eagle's warning (don't laugh)
WARNING: Sheet 1/1: POWER Pin IC2P VSS connected to GND
WARNING: Sheet 1/1: POWER Pin IC2P VDD connected to VCC
Vss must be 0v, so what's the problem connecting it to gnd? should the oriental circuit be redesigned??
WARNING: Sheet 1/1: POWER Pin IC1P V+ connected to VCC
WARNING: Sheet 1/1: POWER Pin IC1P V- connected to GND
another thing, according to datasheets the LM3914 and LM3915 share the same pinout, but could be used indistinctly with the oriental circuit? (I prefer the shame of asking, instead of blowing the money up)
