I build myself a home server last year, without any particular plan just to try it. Specs: Ryzen 7 3800X, 32 GB ECC RAM, 2 TB HDD and 500 GB SSD. I use it to run PLEX, Torrent, TrueNAS, WireGuard, NextCloud, and my side projects.<p>The server runs Proxmox, some of these services are separate VMs, others are running as Nomad jobs. I also have a dedicated development VM which I can access remotely through the VPN wich is pretty nice.
Used to! I restored vintage oscilloscopes, played around with high voltage and low noise power supplies, and did some microwave stuff, too. Of the scopes I used, one was a tek 556 dual beam vacuum tube scope, and the other a 2 GHz lecroy for everything else. I had a 20 GHz specan, 6 GHz VNA, a handful of power supplies, hot air rework and all that good stuff. Now I’m doing a postdoc and have joined a group that’s much more tinker-oriented so the lab I work in is a big mix of research stuff with a few personal projects. The major one now is a machine for rewinding the specialized HV transformers in the 500 series scopes that I love so much.
What sort of "lab"? I've recently created a home manufacturing "lab" in my apartment due to Covid-19. I'm cooking up electrodes (EEG), soldering PCBs, silicone enclosures, 3D printing and sewing.<p>I'd like to be testing cortisol, GH, and a few other things but don't think that's possible in a home lab. Let me know if I'm wrong.
No home lab to report, but this is a chance to recommend for:<p>Invest in uniform, stackable storage boxes. This can pay off over apartment and house moves, and decades.
I got motivated to have a mini cluster from an old blog post by the person who did duckduckgo. There is a website called servethehome (sp?) that has useful resources. My home cluster did not age well .. it still has a ton of RAM and cores but I worry about my power bill when the beast is running.<p>I also have a nice desktop with a 3090 for DL stuff and a modest electronics hobby lab (basic stuff like oscilloscope, function generator, bench power supplies along with a healthy stock of MCUs and electronic components).<p>On the fabrication side, I have a 3D printer and just got a cricut (hoping to use it as practice for intricate prints on the library epilog, which I have accessed in the past).<p>I also have young kids now and time is scarce. I'm really trying to teach the oldest one (5 years old) and some days are really rewarding!
I have a pair of white box ESXi hosts. The specs are.<p>Ryzen 5 3600, 64GB DDR4 RAM, 1TB NVMe SSD ASRock Rack X470D4U Motherboard
Ryzen 9 3900X 64GB DDR4 RAM 2x 1TB SATA SSD ASRock Rack X470D4U Motherboard<p>I have a VMUG Advantage Membership, so I have a full VMware stack running. I recently setup Tanzu to start learning Kubernetes. Since it is just a lab for shared storage I just have a Linux VM running on one of the hosts with an NFS share. Guess that counts as hyper-converged. I could setup vSAN, but I'd need get get a couple of more disks and another host to use as a witness. This solution works for me. Plus vSAN uses a lot of RAM.
Is there an accepted definition of a homelab? Will my Raspberry Pi 4 running TiddlyWiki and a few custom scripts count ? :)
What about an Intel NUC that is running a Plex Server and a blog ?
Yep! An Intel NUC running TrueNAS w/ a bunch of external HDDs (yes, I know the risks), an old laptop running Hassio (processing video frames through TensorFlow all day), and a router with FreshTomato. It's not perfect, but it was cheap and it gets the job done.<p>Running about 10-15 Docker containers on there, an instance of Windows 10 Pro (to RDP into because I don't want it anywhere near my dev machine), and two Minecraft servers.
I have a 4 node Raspberry Pi 4 k3s cluster that I use to run some scripts, a 4 node Raspberry Pi Zero W Cluster that I'm planning on trying barebones Hadoop on, a Pi Zero W running PiHole, and a whole bunch of Arduino and STM32 devices I use to build my keyboards. I also have samba running on one of the Raspberry Pis, with an 8 TB hard drive connected to it, for my movies and media.
Depends on what you mean by lab.<p>The first thing that comes to mind is my flow hood, glove box hybrid work area that I use for culturing mushrooms (not <i>that</i> kind).<p>From a tech standpoint, I also have some Pi and Audrino stuff. I have a laptop that I use for a lot of dev stuff. Although I'll use my desktop for big data since it's beefier.
Half of my home office is setup for video recording.<p>The robotic projects are stacked on the shelves among the book. At some point I am going to setup my soldering station in my basement along with my tools.
Currently running 4 Dell 5820s + A S5148 switch for a home Kubernetes cluster. It was built with running production grade workloads in mind, and serving that purpose fairly well :)
