some small questions

MIDIbox HUIs
1

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!)

  1. i have 50 kohm faders… will it be okay ? i remember i had problems with

100k pots… will these 50k be okay ? if not, i don’t remember how to make

them work (i cannot replace them for my specific project!!) WITHOUT jitter…

any idea ?

thanks in advance!

  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?

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,
