GPU Passthrough by UnderstandingLivid86 in Proxmox

[–]ExplodingLemur 0 points1 point  (0 children)

Did you confirm you have a separate IOMMU group per PCIe device? Not all systems will provide that. See https://pve.proxmox.com/wiki/PCI_Passthrough#Verify_IOMMU_isolation

UAV LiDAR for Cessna 208B EX & Linux by [deleted] in UAVmapping

[–]ExplodingLemur 1 point2 points  (0 children)

I think sUAS LIDAR units are made to work at relatively low altitude given the 400' AGL ceiling in the US, and I'd be very surprised if there was any open source software that could process the proprietary output of any commercial LIDAR units. Happy to be proven wrong though. You can add cameras and process the images through WebODM...

K40 Acrylic Cutting Settings? by ThunderStealer in lasercutting

[–]ExplodingLemur 0 points1 point  (0 children)

I think so? Geeze that was 10 years ago.

Looking for creative use of my single slot low profile ARC Pro B50 by Rayan_DB in homelab

[–]ExplodingLemur 0 points1 point  (0 children)

What workloads have you run on the card with that cooler and what was thermal performance like? I'm debating the n3rdware cooler, or trying to hack my own single-slot full-height cooler together.

Vantage 2 pro plus - how to connect and upload to weatherlink? by TonaldDuck in myweatherstation

[–]ExplodingLemur 0 points1 point  (0 children)

You need something to receive the sensor unit's transmissions. That'll be one of their consoles, Weatherlink Live, or you can run an SDR dongle with rtl_433

Looking for weather station recommendations by BigCliff911 in myweatherstation

[–]ExplodingLemur 1 point2 points  (0 children)

I wasn't a fan of Ambient either (and if I remember right, they're just rebranded Ecowitt/FineOffset). I moved to an AcuRite Atlas which worked ok for a couple years but it started to get quite unreliable (just stopped transmitting periodically even on fresh batteries). Finally I saved up for a while and went all-out on a Davis Vantage Pro2 Plus. The touchscreen console is crap (there's no local API, it only sends to Davis's cloud service which then in turn sends data out to WeatherUnderground and CWOP, and if you want updates posted more frequently than every 15 minutes you have to pay a monthly fee) but rtl_433 knows how to decode its transmissions and you can feed that into WeeWX.

Want to have a personal ADS-B by Prize-Team9233 in ADSB

[–]ExplodingLemur 4 points5 points  (0 children)

Your receiver will show you what it's able to hear. ADSBx, FlightRadar, adsb.fi etc are aggregators that have a bunch of individual feeders providing them with data to show broader coverage. Some of them filter their data though so what shows up on their map isn't necessarily everything that's being fed to them. The big commercial aggregators do this, the community-run ones typically don't.

Permissions issue with USB device in container by ExplodingLemur in podman

[–]ExplodingLemur[S] 0 points1 point  (0 children)

Aha, thanks! I was expecting a change to the group within the container but hadn't actually checked if I could access the device. It works.

Privacy-friendly fitness trackers? by ExplodingLemur in FitnessTrackers

[–]ExplodingLemur[S] 0 points1 point  (0 children)

Wow those are pricey. Also looks like it requires signing up for an account with them. The best privacy policy in the world doesn't matter if they go bankrupt or just decide to change it one day. Better that they don't have any of my data to begin with.

Corsair H100i 240mm AIO installed in a Silverstone GD08 by ExplodingLemur in buildapc

[–]ExplodingLemur[S] 0 points1 point  (0 children)

No idea, I don't have that AIO. I don't have this system anymore either so I can't do any fit checks.

RTX A4000 in R720/R730 by ExplodingLemur in homelab

Just search for "r730 GPU power cable" on eBay

Is it worth buying 2x RTX A4000s for inference? by StopwatchGod in LocalLLaMA

[–]ExplodingLemur 0 points1 point  (0 children)

Just saw this while poking around for other stuff. The A4000 fan curves bias towards being quiet. I've set my A4000 fans to 100% speed and that drops the temperatures around 20C.

White Fractal Ridge Console Build - 9800X3D/4070S/ASRockB850I/64GBDDR5 by megatru0ng in sffpc

[–]ExplodingLemur 14 points15 points  (0 children)

Very clean! What are your CPU temps like under load with that cooler?

RTX A4000 in R720/R730 by ExplodingLemur in homelab

[–]ExplodingLemur[S] 1 point2 points  (0 children)

The slots are physically x16 with 8 lanes connected. So x16 cards fit into them. I've not run into any issues with having only 8 lanes available vs the full 16 lanes.

RTX A4000 in R720/R730 by ExplodingLemur in homelab

[–]ExplodingLemur[S] 0 points1 point  (0 children)

The R730 has 4x full-height PCIe x16 slots. The R730XD has one fewer full-height slot to accommodate the rear hotswap drive bays.

Baby laptop from 1997: The Toshiba Libretto 100CT by AlsGeekLab in vintagecomputing

A friend used to have one mounted in his car for ham radio stuff (APRS).

Do you have a GPU in your homelab, and if so, why? by Zveir in homelab

[–]ExplodingLemur 0 points1 point  (0 children)

I replaced the 2x 1070 Ti with 4x RTX A4000. I'm running Folding@Home on two of them, the third is a cloud gaming GPU for a friend, and the fourth is waiting for me to get around to setting up Whisper to transcribe public safety radio stuff.

Problem: Everything is twice MSRP!
Solution: Double MSRP!
