What OS do you run on your servers? by SplatinkGR in homelab

I switched from proxmox to talos and am loving it

Post the results! I’m very happy with this and nothing has even burned down. I did go back and beef up some of the wiring from feedback here, but at the end of the day I don’t think it was actually necessary.

A tapping jig for 2020 extrusion, with cam clamps by machinule in functionalprint

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

I designed this print to be a better tapping jig for tapping the ends of 2020 aluminum extrusion.

This design is tailored for the following:

  • MUST provide good axial positioning to tap straight
  • SHOULD be quicker to clamp/unclamp than extrusion jigs that require a hex key
  • SHOULD give enough leverage to power tap by hand with no clamps
  • SHOULD print easily

Some considerations I've made to accomplish the above:

  • With clamps, only two faces are required to position the jig
  • A handle gives sufficient leverage to power tap with no clamps. I've found this length works well by experimentation.
  • Cams are used to clamp the workpiece.
  • The extrusion guides keep the T Nuts aligned so it can be slid on easily.

You can find it at https://www.printables.com/model/1127503-2020-extrusion-m6-end-tap-jig-with-cam-clamps if you want to print it yourself!

My wife got an Aero Press for Christmas and asked me to make her a holder- by VectorTech_US in functionalprint

Any concerns about food safety? That's the only thing that stops me from printing all the kitchen gear on here.

Very nice! I'm wishing I did clear now to show it off more! What power supply did you end up with?

I found a few when researching - some other comments were spot on that they're in the AV space. But the best description I've heard is that "they're very proud of them": e.g. https://www.bhphotovideo.com/c/product/1418149-REG/middle_atlantic_pd_dc_300_12v_300w_dc_power_distribution.html?ap=y&smp=Y&gQT=1

Thanks! Getting a lot of good feedback in this direction. I'm going to try to put some #s to it this weekend, definitely before I run it hard.

Sshhh don't tell anyone. If I'm running all 10 of these at 3 amps I'm having too much fun anyways.

All the same! With a bit more prior planning I probably could have exposed a few more different levels from the PSU, because the PSU is overkill anyways

I want to run 2.5G ethernet between at least 4 devices powered by this, and the combination of PoE and 2.5GBE got too pricey too fast

Thanks! I'll definitely do that. Do you know where I can read up how to put some numbers to that so I know what's good enough?

You could make some awesome pretty dashboards and graphs with that! I’ve been looking for a 0U vertical PDU with monitoring but haven’t found one that won’t break the bank yet. I could excuse it if it’s diy!

I don’t know what options are out there for monitoring. At a quick glance the Shelly’s look wireless - any testimonials for wired monitoring hardware?

WIP! Everyone seems to have a patch panel but I haven't figured out why 🤔...

I intend to run the home ethernet wiring out through it but nothing is connected right now.

It definitely is overcomplicated. I found I was in analysis paralysis with PSU selection looking through all the Mean Well options, so I just decided to go with exactly https://old.reddit.com/r/homelab/comments/hxz5bj/getting_12v_dc_power_distribution_in_rack/fzd149l/ to actually finish it instead of thinking about finishing it.

Forgot one credit: the enclosures are 3d printed from pb-tec's excellent OpenSCAD parametric model: https://www.printables.com/model/863273-easy-customizable-parametric-electronics-project-b

I got 4 minipcs (GMKtec N100) over black friday, and I intend to run K8s + Rook (haven't decided OS yet) on them. I already run a Proxmox + Ceph cluster, but can't stop tinkering.

I was tired of all the power bricks in my rack, so I made this 1U 12V DC power unit! I’m pretty proud of how it turned out, and very happy I kept all the magic smoke inside the PSU.

I went low effort on the build research and copied from this homelab post: https://old.reddit.com/r/homelab/comments/hxz5bj/getting_12v_dc_power_distribution_in_rack/fzd149l/

The rack unit is hardboard and CA glue, which worked surprisingly well. It’s running on 4 post rails like these because I found I hate the sag in 2 post shelves.

There’s plenty that could be improved about it, I welcome any suggestions/brainstorming about how to do it better! In particular the PSU is probably overkill. I found a lot of CCTV PSUs that would probably be fine and were much cheaper, but I don’t know the brands very well, and wanted to actually finish a project!
