I got 5 boards, a Quneo midi controller and a 10000mA usb-powerbank, giving 5v at 2.4A over two usb-outputs...
Is the output of the powerbank enough to power this all?
I know there's enough energy in it as it could run 2 axoloti's and the Quneo for over 24 hours while still having half of the accu left, but not sure whether it could drive this all together at the same time.
I was planning to use an USB-hub to power multiple axoloti's from a single USB output from the powerbank and then use the other output of the powerbank to power the axoloti that also powers the Quneo. So that would be 4 axoloti's on a single usb-power-hub, while the other output is powering an axoloti and a quite power-hungry midi controller, because of all the LEDs.
Next to this, I'm wondering about how to connect the midi between the modules.
The plan here was to use a single axoloti as a general midi sequencer and midi-clock generator.
Then hardwire the midi-output of this board to the midi-input of 2 other boards (1->2 and 1->3) and have the midi-output of these boards hardwired to the last 2 boards (2->4 and 3->5).
Thing is, I read here about the use of opto-isolators and I'm not sure I got the right one here (got a bunch of old electronics that I can use as scrap)... is it actually necessary to use these when splitting the midi signal only into 2 outputs?
eg. wouldn't it be possible to just use diodes, driven by the midi signal, to switch the signal on/off?
and ps. I thought midi-signals were like "bitwise" signals, just sequences of on/off signals at a certain rate..? if that would be so, just re-amplifying would be enough I'ld say...
