SORRY IF THIS HAS BEEN ANSWERED BEFORE! BUT! do the androids ever need to charge? or do they purely run on thirium? like are they solar powered? do they have wireless charging pads they sleep under? like how does this work /gq

NO THATS A VALID QUESTION!! Honestly the actual dbh wiki is an unprecedented amount of unhelpful so I have to make everything up myself /silly

Afaik, thirium is only ever described as the fluid required to power the androids’ “biocomponents,” aka organs, aka individual modules that each power, like... A function. For example, there’s an audio biocomponent, the eyes are biocomponents, the thirium pump and thirium pump regulator are both biocomponents, etc etc etc. So technically, as long as an android has thirium, their biocomponents should be able to work just fine? But it seems improbable to me that an android could just work and work and work and never get “tired” (less effective, worn down over time, fried, etc). So in dbhc, the way the androids were first designed by Xisuma meant that they could only work for so long before they needed to go into a Low Power Mode of some sort, aka to rest (so their circuits and insides don’t fry from overuse).

Later, sometime late s8 or early s9, xisuma and doc tweak the androids’ OS so that Low Power Mode works more or less like sleeping (as an option to androids who want more of a human experience). Instead of the androids needing to sit/stand somewhere and be sort of inoperable/limited capability for a few hours, an android will start getting “sleepy” or low-inefficiency/sluggish/etc after a certain amount of time and then require proper rest (I’m sure that x and doc time it so that androids are running on a clock similar to human bodies—aka, active for about 12-16 hours a day, needing rest for 6-8 hours, etc). While they can’t necessarily control the when the “sleepiness” comes on (such as when they’ve been working harder/running hotter one day and need rest sooner), I think I imagine that the androids do decide when to trigger or start sleep procedure/sleep mode/low power mode or whatever.

So, they don’t need to “charge” per se, but they definitely need rest! Giving them a rest period also makes Impulse’s specialty more meaningful, since he was designed to be able to work for longer periods of time without rest/carry heavier loads :]

Alright RAM and headset have been ordered. They won't get here in time for this weekend's game of Enshrouded but next weekend should be good.

I don't know a whole lot about RAM. I ended up getting the Corsair 64gb modules. It has 3600mhz. I'm not sure how great that is for DDR4 but it's faster than the cheaper memory sticks that were 3200. I see DDR5 is up to 6000mhz but that requires a new motherboard.

As for the headset it has 3 input modes. There's a bluetooth option which I'm going to avoid since I'm sure that's what's causing my current audio problems. There's a 2.4ghz USB dongle for non-bluetooth wireless. Finally if all else fails there's an option to use an AUX cable.

My next weak point in the system is my video card. I have a GTX 1660TI with 6gb of V-RAM. Since I don't care about ray-tracing and I hardly ever play any new games it shouldn't need to be replaced anytime soon.
