jeb Posted December 10, 2007 Report Share Posted December 10, 2007 hello,i've made several small midiboxes (one year ago... see my other post)... i'm currently building a new one, and i have one or two small questions...1) what range has been tested for power ? is 12V AC ok or too much ?2) is there an interface for a power led (i don't want to build a ?OUT module for this!)3) i have 50 kohm faders... will it be okay ? i remember i had problems with100k pots... will these 50k be okay ? if not, i don't remember how to makethem work (i cannot replace them for my specific project!!) WITHOUT jitter...any idea ?thanks in advance! Quote Link to comment Share on other sites More sharing options...
SLP Posted December 10, 2007 Report Share Posted December 10, 2007 1) I think the 7805 can handle up to 18V input voltage.2)Why don't you just connect a LED with a resistor in series after or before the 7805?3)they *should* work. I'm not sure. Why don't you just test one on one of your working MBs?matthias Quote Link to comment Share on other sites More sharing options...
Tanstaafl Posted December 10, 2007 Report Share Posted December 10, 2007 Jeb, I use a 13 volt ac wall wart with mine, no problems. I also use 50k pots on my MoogModularV / MidiBox, some of the wires are longer than 18 inches so I occasionally get some jitter in those lines, changing to 10k pots on those farther runs seems to clear the jitter problems for me.hope this helps,gb Quote Link to comment Share on other sites More sharing options...
