jwillans Posted June 23, 2007 Report Share Posted June 23, 2007 I've finally built all my kit and successfully tested it independently. It consists of 4 cores, 11 DINs 1 DOUT 1 AIN and 1 4 * 20 LCD. I have two questions:1) Will a single 500ma power the 4 cores in this setup, or is it going to be under powered?2) All the cores work, but some are reading a voltage slightly over 5 (i.e. 5.07), is this normal and does it carry any risks?Thanks,James Quote Link to comment Share on other sites More sharing options...
stryd_one Posted June 23, 2007 Report Share Posted June 23, 2007 5.07 is fine, your meter probably has a greater range of inaccuracy than that :)500mA sounds a bit slim, it'll depend on your LEDs and LCDs... You said it's only 1 DOUT and 1 LCD so maybe....Pics! Pics! ;) Quote Link to comment Share on other sites More sharing options...
jwillans Posted June 23, 2007 Author Report Share Posted June 23, 2007 Thanks stryd_one. No LEDS, the dout are driving ULN2803s. This setup will eventually go into an organ console, but that hasn't been built yet! I'm going to mount it next weekend ready for installation, I'll post some pics then.James Quote Link to comment Share on other sites More sharing options...
jwillans Posted July 1, 2007 Author Report Share Posted July 1, 2007 Would it be wise to use a 1200ma supply? Are there any risks associated with using a large ampage supply like this?James Quote Link to comment Share on other sites More sharing options...
cimo Posted July 1, 2007 Report Share Posted July 1, 2007 hino, the max ampage you can feed has no limit, for the box won t require more than what it needscheerssimone Quote Link to comment Share on other sites More sharing options...
