DriftZ Posted October 17, 2003 Report Share Posted October 17, 2003 But what if your pots are not in rows?Ofcourse they are in rows, use you imagination ;)the starlike thing means, if you have X number of pots, you dont connect them all to 1 ground loop.Example 16 pots:Wrong: GND-pot1-pot2-pot3-.....-pot16-GNDBetter:NC-pot3-pot2-pot1----GND----pot4-pot5-pot6-NCNC-pot9-pot8-pot7----| |--------pot10-pot11-pot12-NCNC-pot14-pot13-------| |--------pot15-pot16-NC(NC means Not Connected to GND on that side)this is a 'star' with GND in the centreetc....Right ? :) Quote Link to comment Share on other sites More sharing options...
Nomical Posted October 20, 2003 Report Share Posted October 20, 2003 Anyone know something about the placement of components on a pcb? Quote Link to comment Share on other sites More sharing options...
Duggle Posted October 20, 2003 Report Share Posted October 20, 2003 hi,follow the general trend of the supplied pcb's of MBHP to a provide basic guidelines.If you keep wires and tracks within the recomended lengths you should be fine.The most important thing for these circuits is a clean powersupply. The 5V regulator on the core is definitely sufficient so long as it is driven by an adequate supply.(9VDC under load).One common engineering practice that Thorsten doesn't seem to follow is to connect 100nF (or thereabouts)monolithic caps across the 5V rail of (each) the logic ic's. This is more of a precausion against glitches that may come about under more or less unusual circumstances. The obvious success of MBHP says theyre not strictly necessary for correct circuit operation. I used them on my midibox out of habit (accepted design practice). cheers Quote Link to comment Share on other sites More sharing options...
