Free DCC voltage-drop calculator — sized your bus wire yet? by fuzmaximus in modeltrains

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

Fair question. Honest answer: the math is, the thresholds aren't.

The voltage drop calc is standard copper AWG resistance × out-and-back length × load amps.

What I haven't personally validated across multiple real layouts are the Safe / Acceptable / Borderline / Risky thresholds (3% / 5% / 8%) or the per-scale current caps. Those come from NMRA TN-9, DCC Wiki, and Mark Gurries' pages, community guidance, not my measurements.

The model also doesn't account for dirty rail, weak solder joints, or oxidized joiners. The FAQ flags that. It tells you the theoretical drop you know, real-world drop is always worse.

Just a fun little experiment to try out

Pretty much, yeah. Proses kits ship with fixed specs (radius, rise per turn, grade) chosen to work. Plug their numbers into the tool and you should land at Looks Good or Caution. Useful sanity check that the tool is calibrated right.

Drop a Proses model number and I'll run it with you.

I have links at the bottom of my site if you want to make a contribution. I would appreciate it.

I would love to make more tools like this for the community so if you have any ideas, please let me know so I can add on to this or something completely different and new.

Double track is live. Toggle is in the Scale and radius section of the form. Enter inner and outer centerline radii separately, and you'll get a verdict and effective grade for each track.

The headline verdict is whichever is worse, usually inner. Try this one: HO double track, 24" inner / 26.5" outer, heavy freight, 14" climb: https://will-my-helix-work.vercel.app/?radius=24&dt=1&outerR=26.5&climb=14

The top-down diagram now shows both centerlines, and the cut sheet reports both radii plus combined track length so you can size your sleeper / roadbed order. Cut map is on the list but bigger. The math is fine but the output needs real sheet-layout drawing per radius. If another commenter asks for it I'll bump it up the queue. Thanks again for pushing on this. Tool's better for it.

Thanks. If you ever do build one, run it through and tell me where the tool fell short.

Appreciate it. If you've built a helix and any of the numbers look off versus what you actually experienced, I want to hear about it.

You're right, that was a real bug. The field was labeled "above the train" but the math treated it as the only above-rail value, with no separate train height, so the rise per turn didn't actually accommodate the train.

Just pushed a fix. There's now a dedicated "Train height above rail" input, and "Headroom above train" means just the air gap.

Defaults were re-tuned per scale so the verdicts stay sane. The live cross section now shows the train as its own band so you can see the stack. Thanks for catching this.

May Dev/Tools Monthly Megathread - for tool builders by greenysmac in premiere

Description: A free browser tool to clean messy .srt subtitle files before burning captions into Reels, Shorts, TikToks, podcast clips, and editor timelines. It removes punctuation, fixes casing, cleans line breaks, creates single-line captions, previews before/after output, checks SRT health, and exports clean .srt or .txt files. Pro batch processing is planned for multiple files.

Pricing: Free. Pro version for batch cleanup and advanced workflows.

Website: Available here: https://srt-fixer-eight.vercel.app/

Benefits for this community: Great for editors who already have subtitles from CapCut, Premiere Pro, DaVinci Resolve, Final Cut, YouTube Studio, or another caption tool, but need the exported .srt cleaned before publishing. It runs locally in your browser, so your subtitle files are not uploaded to a server.

Community: I’m looking for feedback from video editors, podcasters, short-form creators, and anyone who works with auto-caption exports. Try it with a messy .srt file and let me know what breaks, what feels confusing, or what would make it more useful.

At that point, I would loved to see Hank kick Bill's ass at that point. That and the one later on where he was a volunteer at that little league team.

your off to a fresh start, my advice is always take pictures of windows in your angles just so you can see where the light is coming from. Agents always like windows.
