selfservice Posted March 9, 2008 Author Report Share Posted March 9, 2008 the size of the hole is 0.85mm, the size of the etched hole in the copper before drilling (to center the bit) is fixed by the cad and can't be changed but is sufficient enough to give a perfect alignment of the drilling bit.

DragonMaster Posted March 9, 2008 Report Share Posted March 9, 2008 Oh, by the way, is the LPF absolutely necessary, will the module sound too raw without it? (Trying to simplify things) Quote Link to comment Share on other sites More sharing options...
selfservice Posted March 9, 2008 Author Report Share Posted March 9, 2008 I think another LPF is not necessary, the distortion introduced by this poor filtering is distinctive of this kind of sinth Quote Link to comment Share on other sites More sharing options...
DragonMaster Posted March 9, 2008 Report Share Posted March 9, 2008 Hi, I don't want to add an LPF, but to bypass the one on the current OPL3 module. Quote Link to comment Share on other sites More sharing options...

monokinetic Posted December 7, 2009 Report Share Posted December 7, 2009 To start, I've fixed some broken links to the alternative PCB in the wiki and added some new photos to my website www.splabs.it Hi, it is nice of you to come back to us :) Thanks for fixing the links in the Wiki page, I checked them and they work. I have not got much time at the moment as well, too much to do for University. But once I get some etching time again I will let you know.....
