Some efforts in Kicad for a pcb version of the prototype. Still very early stage and my pcb design skills are beginner level, through-hole components only for the moment. production of pcbs at a Chinese pcb factory is done and shipped. waiting on arrival (estimated a week or two). I probably...

maybe we should go into the direction that Hetzner did for this boards. they have an open 2U kind of custom frame just one fan combined with a shroud voor memory, cpu and vrm doing the cooling. hot-isle, cold-isle however is less trivial for a homelab :)

something i'd have to look into. for now the workloads don't seem to require 100% cpu over longer periods. i didn't look at any fan speeds while doing the stress-ng, will have to look later on that. they did start to make a lot more noise when running for a minute or so :) the cpu in this...

A little update on the CSE512 1u case mount I'm trying for these boards : Ryzen 3700x 2x16 = 32GB UDIMM Gelid 1U cooler + stock 1u supermicro case fan (Delta blower style) Supermicro 1u 200w psu (old non-gold certified) On demand scaling governor nvme ssd 1TB Samung 980 dual 10gb x710 When...

@luckylinux , I haven’t decided if and how to put this opensource (yet). When I tried ffmpeg or ffplay directly it was quite (cpu) resource intensive. I’ve been using ustreamer from the pikvm project and this is very low on resource consumption, I believe when specifying the right hardware...

Questions :) and going a bit off topic from the B450 board... My opinion -) 1. esp32-s3 keyboard hid is working with translation for Azerty-BE, no mouse (yet). might look into generalizing it for other layouts such as Nicohoods implementation. 2. thinking about it, might be slow over wifi...

Meanwhile, doing some tinkering with the esp32-s3, keyboard works over wifi and mqtt in a platformio-arduino sketch. Received some aliexpress orders, so: Added an ethernet connection for stability, speed won't be an issue I guess :) Added a very low cost i2c display Moved some of the...

in the mean time I've advanced on the esp32-s3 combined with a lxc container running nginx and ustreamer (low resource < 1% cpu). currently still going through lightweight mqtt messages for the keystrokes using a homeassistant embedded mosquito. meaning you could even automate the bios setup and...

That's very good news for your svga and hdmi capture adapters. I might have to retry my cheap adapter, granted I only tried it on 2 real monitors with SVGA inputs, not the capture card...

That would be very nice ! Thanks Virmach and Asrockrack already !

good question, a usb-hub with 4 hdmi captures is feasable, but adding 4x benfei is not cheap, 9-12 eur each. it almost doubles my total cost (per 4 nodes). I had a lot of trouble to get my low-cost vga-hdmi adapter to work (also in the range of 2-3,- eur), very few low-resolutions worked the...

latest version is on printables.com

Another short update. I'll be writing it up on a github project or so if time allows it. tried the usb hdmi capture stick (no name thing) Bus 003 Device 002: ID 534d:2109 MacroSilicon USB Video Device Descriptor: bLength 18 bDescriptorType 1 bcdUSB 2.00 bDeviceClass 239 Miscellaneous Device...

Ah yes, that's exactly why I created a new version for it :) B450d4u 3mf and this is the changelog of yesterday :) no holes yet for screws. : fixed in v1.5 the connectors at the bottom need to be slimmer, fixed in v1.5 the margin around the vga connector needs to be increased fixed in v1.5...

Another small update: The benfei vga to hdmi adapter arrived. what works right now: using a laptop and cheapish usb3 hdmi capture stick using OBS on Windows 11 I can see the bios screen, F11 brings the boot selection menu, and I can see the proxmox console now. that should be enough for my...

could work, depends how the default io shield looks like looks like. i think so since the original io shield design was for X470 in a supermicro. as long as the original shield from the case has this 1u shield format size (don't mind the connectors on this supermicro X9SCL-F shield)...

Aren’t we forgetting the nanokvm (lite) ? Put them in a fenced vlan or so…

prices do fluctuate. i got these cse512 cases including 1u power supply for 17.99,- eur /each back in 2017, some of them had 1U angle risers (pcie 3). in fact I only bought the cases with a X9SCL-F to avoid damage of the mainboard in shipping... so if I sumup a 1u case 3700x compute 32gb ddr4...

yes, exactly, the esp32 does usb hid for keyboard and mouse and the gpio's do the atx power/reset control. granted i manage quite well with wake on lan and autoboot on power-on for the moment :)

Not required to customize, the x470 is similar but would leave some open space. Serial port extra nic, ipmi nic. Our b450 has far less connectors populated. It’s also cleaner like this. I wanted a design to work on anyhow to add a holder or something to fit an esp32 on the free space, with the...
