| GyrosGeier | I mean \o/ | 20:00 |
| erlehmann | mntmn, this is GyrosGeier. GyrosGeier, mntmn is the head of REFORMs. | 20:00 |
| mntmn | hey GyrosGeier thanks for dropping by | 20:01 |
| GyrosGeier | np | 20:02 |
| mntmn | erlehmann told me you had some ideas of how to improve the power system of reform. i was also thinking in the direction of multi cells to get a higher voltage | 20:02 |
| mntmn | i'm looking for the most simple way of accomplishing that | 20:02 |
| GyrosGeier | multi cells is good | 20:03 |
| GyrosGeier | most laptops use 4S | 20:03 |
| GyrosGeier | charge with 19V and a buck converter | 20:04 |
| erlehmann | GyrosGeier, i remember you told me that you would do the voltage regulation thing differently? but i have no idea how and why | 20:04 |
| GyrosGeier | discharge through a buck converter to 12V | 20:04 |
| GyrosGeier | so no boost converters required | 20:04 |
| GyrosGeier | boost converters have shite efficiency and require lots of input current => lots of resistive loss in the batteries | 20:05 |
| mntmn | yeah | 20:05 |
| mntmn | i've had some problems with the high current @ low voltage already | 20:05 |
| mntmn | i noticed that the lifepo4 cells don't really seem to care about any charging "intelligence" unlike other chemistries, so i'm trying to find a simple approach for charging 2 or more cells in parallel... i think i don't need energy transfer between the cells | 20:07 |
| GyrosGeier | I'd just not bother | 20:08 |
| GyrosGeier | you want a battery gauge anyway | 20:09 |
| GyrosGeier | so you need to add a management IC | 20:09 |
| GyrosGeier | so why not use one that has intelligent charging? | 20:09 |
| mntmn | some kind of all-in-one solution? | 20:09 |

| GyrosGeier | balancing is always separate for some reason | 20:40 |
| GyrosGeier | but charging + current maesurement belong together | 20:41 |

| mntmn | verbraucht im memory suspend 0.58A @ 5V | 21:04 |
| GyrosGeier | das ist ein bisschen viel | 21:05 |
| mntmn | ah sorry, german schmerman | 21:05 |
| mntmn | yeah it's because 1 core is not really sleeping afaik | 21:05 |
| GyrosGeier | mmh | 21:05 |
| mntmn | because of some kernel bug, if all cores are put to sleep it can't wake up anymore | 21:05 |
| - erlehmann (QUIT: Remote host closed the connection) (~erlehmann@x59cc896f.dyn.telefonica.de) | 21:05 | |
| GyrosGeier | sounds like POWER | 21:06 |
| GyrosGeier | if all cores sleep, then the only way to get the system back is /S_RESET | 21:06 |
| mntmn | ugh | 21:06 |
| mntmn | you have a POWER system? | 21:07 |
| GyrosGeier | several | 21:07 |
| + erlehmann (~erlehmann@x59cc896f.dyn.telefonica.de) | 21:07 | |
| GyrosGeier | I also built a POWER system once | 21:07 |
| mntmn | ah cool... power9 as well? | 21:07 |
| GyrosGeier | I have a POWER9 | 21:07 |
| GyrosGeier | and the one we built was POWER5 | 21:07 |
| GyrosGeier | that was 2017 :) | 21:07 |
| mntmn | is it the talos or some kind of server? | 21:07 |
| GyrosGeier | I have a TalosII | 21:08 |
| GyrosGeier | the one we built was a dual socket Cell based server | 21:08 |
| mntmn | woah woah. in berlin i guess? you got my attention | 21:08 |
| mntmn | how do you like it? | 21:08 |
| mntmn | how good is it at emulating amd64 ;) | 21:09 |
| GyrosGeier | yes, in Berlin | 21:09 |
| GyrosGeier | we have two people with TalosII in the AfRA | 21:09 |
| mntmn | wow. | 21:09 |
| GyrosGeier | so far mine isn't set up because I need money for other things | 21:09 |
| GyrosGeier | and I don't have RAM for it yet | 21:09 |

| GyrosGeier | I'm still undecided what kind of RAM to buy — 8×16 GiB so all channels get used, or 2×64 GiB so I have more empty slots for the future | 21:10 |
| mntmn | haha this is a nice problem to have | 21:11 |
| mntmn | i was thinking very hard about getting one. but i couldn't find schematics online? do they ship schematics? | 21:11 |
