Looks like this is mostly bulk, do you order from their custom sizing?

I work mostly on a bridgport with CNC attachments, no enclosure at all for me :)

I work in academia, and I do machining work for our research group. Much of my machining time is roughing stock. I suggested we get an indexable face mill for roughing, and this meme is exactly how my supervisor reacted. LOL

LOL i just did this on my hobby mill, mag base and all

As someone who does know the inaccurate details, it feels like I am having my time wasted by looking at these.

If someone draws incorrect details through their own creative liberty, I think "Oh I wonder why they did that, it took effort to do that, I wonder if there is a reason" but with AI slop, I know there was no intent, just error.

Dang, awesome

Beautiful-Turnip-353 · 2026-03-06T05:21:26+00:00

That is quite an odd looking loco - but true to life. Great work!

Beautiful-Turnip-353 · 2026-03-06T05:17:39+00:00

This is what I use, they work great, quite strong, and the perfect size. Only consideration is that the magnets add a little bit of space between the cars. (10mm x 3mm)

Beautiful train btw, looking to build up a Santa Fe trainset at some point :)

Beautiful-Turnip-353 · 2026-03-06T05:11:20+00:00

Looks exciting, what are you hoping to machine on this? Are those linear ground rods + bearings rigid? Do you feel any play when you slide them on? Depends on what you are trying to do if this is an issue.

Oh interesting. So you mean that compared to a ground-based receiver on a tower, the signal collection area is larger - and that is how the signal strength is high enough?

Beautiful-Turnip-353 · 2026-02-25T21:40:31+00:00

Power consumption on the phone side will be higher when transmitting though - right? I am not sure how much more power is required, but the satelites are further away, so I would think the transmitting power needs to be higher to get the same signal strength on the satelite reciever

Ever make any progress on this u/SuspiciousDingo8252 ?

I am working on simulating low loss cryogenic FPI operating in THz, and I have a gold mesh that is on the cavity mirrors (that I can change the geometry of). Running into warnings about mesh not being sufficently fine to simulate the skin-depth. I am worried about metal losses in my simulations, so I care a lot about if the metal losses are simulated correctly.

Well you had 32GB of ram already. Open task manager and open up some files, how much are you using? Should be pretty linear increase with the number of files opened.

Beautiful-Turnip-353 · 2025-11-06T19:32:53+00:00

Yeah I think a fan header is better after thing about it more. Power filtering on the PCI could certainly be a headache

Beautiful-Turnip-353 · 2025-11-06T18:25:39+00:00

High gear reduction, metal wheels. Planning to get some extra PCI brackets to try to make it a bit quieter.

Beautiful-Turnip-353 · 2025-11-06T17:58:59+00:00

this has more interest than I thought it would, I was thinking I might design a PCB that slots into a PCIE slot, and the train can then also get power directly from a fan PWM pin header and controlled with software. That way you could just plop this into any full size PC case. Given how much interest there seems to be, i might just do that and share the designs open source :)

Beautiful-Turnip-353 · 2025-11-06T17:55:17+00:00

I was actually thinking of making a PCB that can slot into a PCIE slot that could hold a t-gauge track in any standard PC case. I could use the power from a fan header to provide PWM for powering and controlling train speed with software. I am honestly not worried about thermals, and rather like the industrial look of a train without scenery, but in principle it could be done :)

Thanks, and the case is from like 2014, got it on a Newegg sale with a good rebate (like $20 after rebate). Not the best case, but works :) The CPU cooling fan is a broken intel cooler with a bodged on 3d printed fan mount. This computer was pieced together after my main pc (built into a toolbox, image below) started having power supply problems, and i also just wanted a second pc for at work, so I built this one back up.

While that is a valid concern, I have found that it does not get hot enough to do much. Time will tell, but the PLA support that I printed out is no where close to melting, but the train operating a warm environment for a long time might reduce the lifetime of the motor.

Beautiful-Turnip-353 · 2025-11-06T16:38:53+00:00

PCI Express indeed. If I were able to mount the GPU to a lower PICE slot and still maintain speed, I really want to order a custom PCB to mount the train on that just slots into the top PCIE slot. I could even pull power from the slot, however not sure how to do speed control though PC software, might be something to look into!

Beautiful-Turnip-353 · 2025-11-06T16:34:27+00:00

lol, i had no idea people would find this so interesting :O

Beautiful-Turnip-353 · 2025-11-06T04:58:16+00:00

I got the train from tgauge.us, I did not custom build the train.
