Wilba can.
Screen and LEDs. Yes.
It's not like LEDs or an LCD really take up less/more space when you do not put holes in the panel :yes:

When it comes to tube preamps/classy tube sound/analog warmth you'll get 11 different opinions for every 10 guys you ask. I'd suggest visiting a well sorted music store or trying to find some A/B clips online.
Assuming you haven't done any tube or HV projects, I'd suggest starting with a low voltage one and pretend it's HV - even if the sound may be a lot different from an incredibly cool awesomely hot running tube :flowers:
Some hundred volts through your body fizzle quite a bit and make you jumpy for the rest of the day. Or dead.
I can highly recommend toying with some of these: http://www.tube-town.net/diy/lov/lov03-bananabooster-eng.html
Cheap, easy, low voltage, still nice :) You'll want to adjust the input impedance though as it's geared to'rds guitars.
There is none.
Obviously.
Your average LC display doesn't even display changes properly if the update rate is > 20fps since they're typically very sluggish, so anything above that is a waste of CPU time anyways.
MIOS8 by default updates the SRIO chain @ 1kHz.
8 enable lines => 1kHz/8 = 125 Hz.
Sidenote (for more detail read the datasheet): The 25ns is the time it takes to switch the pin. Not the time it takes for you to write the entire shift register.
..und bevor die fertige Maschine vor Dir steht darfst Du gerne jederzeit Fragen - allerdings ist es echt reichlich schwierig derart allgemeine Frage genau zu beantworten. Gib uns was womit wir arbeiten können und Du wirst sehr hilfreiche und detaillierte Antworten bekommen.
Apparently I do not need to hurry building mine then. Maybe, just maybe you do wanna wait until at least one or two of the prototypers have built there's an possibly come up with something? Just a thought.
