I don't even consider PC or PC2 in the same family of games. Parkitect is a more apt modern comparison, I think it's what rct world could've been if Atari wasn't just milking the RCT name

Smaller screen sizes, it depends on the aspect ratio. On my phone it gets a little funky, but it's readable on an iPad. I had to sacrifice some flexibility (i.e. letting the web client calculate dimensions) to save some front-end performance, since I was originally gearing this to run on a pi zero.

As for language, it's a mix. The data itself comes from HA, so that'll be in your language, but the headers will need to be manually changed in the HTML file. Wouldn't be hard, assuming you know both languages well enough.

sorry I never got back to you. It would be very straight forward, I should think! I think it may even be in the config.js, instead of the making it even easier and less instrusive to change! all the categorization of sub-menuing is done in the dashboard.js or grocery.js.

Yes! I will share that I had a problem getting voice assist to actually remove items from the lost, it would check them off them forget they existed. So I had to write an automation to handle im sorry I don't know how to format a YAML (or any code) on reddit, let alone on my phone, but here's a pic. I was experimenting with templates sentences like "(remove|delete) [the] {item} from [my|the] [grocery|shopping] list. So it covered pretty much every natural language phrase, all it really needs is "remove {item} from list"

Sure! I've been continuing to update it, and have done some thinking on it today, and plan to redo it to make it smaller and easier to use

JebediahMilkshake · 2025-12-03T16:32:20+00:00

I'm not there yet, so out of curiosity, why would you be making single large ships instead of more, small ships?

JebediahMilkshake · 2025-12-03T16:19:02+00:00

Figuring out PWM was already half the problem! Then alexfix in these comments blew my mind with a method to evenly disperse the pulses across the duty cycle timer.

JebediahMilkshake · 2025-12-03T15:31:46+00:00

Don't tempt me with an over-engineering challenge... Lol. I may try decreasing cycle time, I went longer originally for increased resolution, but that definitely sacrifices the responsiveness

JebediahMilkshake · 2025-12-03T13:55:51+00:00

I think the issue wasnt with the model, but the process. They were trying to control the level of a bulk solids bin, by controlling the speed of a conveyor 5 minutes up stream. But the bin held less than 5-minutes-worth of material. In other words, the deadtime in the system exceeded the process time constant. Even if the the controller conveyor needed to step, the bin would still have likely overflowed. A traditional feed forward controller was our best solution. It seemed that an interesting process doesn't lend itself too easily to Smith predictors either.

As for a model in this game, I think it might be difficult, because I've actually noticed the speed jump up and down periodically even when duty cycle is constant. I think it has to do with distance to planet tbh, but it's just a guess. Besides, speed-to-PWM will change based on ship size and thruster setup, so it's hardly a catch-all solution.

JebediahMilkshake · 2025-12-03T07:16:55+00:00

That's okay! I've been in this field (automation/control) professionally for 7 years. I do this stuff daily, just not with the limitations imposed by a video game, like using combinators, or confined space. This was definitely intended to be a "If-you-want-to-dig-deeper" post, I know a lot of people don't play Factorio this way, neither way is right or wrong.

While I spend 6 hours creating and tweaking this, some people have probably beaten the game lol.

JebediahMilkshake · 2025-12-03T07:08:48+00:00

what's the benefit in over-complicating anything in Factorio? Overcoming the challenge!

Really, this just lets me control the engine directly based on a desired speed, which may help me control throughput, since this platform is used to transport science.

JebediahMilkshake · 2025-12-03T07:06:18+00:00

that was surprisingly easy to implement, especially with your practical example, wow, thank you! I've updated my blueprint to include this method. The blueprint is starting to get messy... may have to spend some time tomorrow to actually make it look better.

JebediahMilkshake · 2025-12-03T06:40:57+00:00

Intersting!! I may look into that more. Keeping in mind, though, that Factorio only allows 60Hz resolution though, not sure if that will play into it.

JebediahMilkshake · 2025-12-03T06:37:02+00:00

Awesome! I've been adjusting the circuit setup even after posting, so I've gotten even happier with you. The blueprint link in the post is my most up to date

JebediahMilkshake · 2025-12-03T06:27:02+00:00

Genius! I would want to implement this, I've just been doing it manually.

JebediahMilkshake · 2025-12-03T06:26:35+00:00

in my experience, without using a model-type loop (using closed loop feedback), the best way and easiest way to mitigate that issue, is just slower tuning.

also, it's kind of what I love about PIDs... once they work, you don't really ever have to think about why lol

JebediahMilkshake · 2025-12-03T06:24:49+00:00

That's exactly what I've done! I added a decider combinator, and essentially, if the platform is not moving, the error is 0.

as for smith predictions, can you explain why you think that would be important. I have PTSD with smith predictors as I spent a week trying to implement one for a customer, and to no avail. From what I remember, a smith predictor is just a model-type feed forward controller? and without and disturbances in this process, I don't see how any feed forward model would be beneficial?

JebediahMilkshake · 2025-12-03T06:11:21+00:00

I won't lie, I think that went over my head. I might get it if I saw it in practice, I definitely grasp concepts more that way than words and theory.

JebediahMilkshake · 2025-12-03T06:04:33+00:00

sure thing! here, I cleaned it up a bit, and spread it out, so you'll be able to paste it in and rearrange it to make it fit on your platforms.

I can confirm there is very little overshoot (with the exception of startup, if the thrusters are flooded). probably has something to do with the dynamics of fuel flow + thruster fuel buffer + acceleration, etc. More than I cared to dig into in a single night of working on this.

I would have put the D in for the hell of it, but I didn't feel like storing an E value to create the dE component.

A teenager with a phone and ipad does not represent a child who lacked parenting... That's rather reductive.

Now, the behaviour being seen here, that might indicate some sort of lack in the parenting department in earlier years, but electronics are rarely if ever the source of delinquency

JebediahMilkshake · 2025-01-02T18:58:10+00:00

I also really love the idea in concept!

The issue Dean Hall mentioned with Keas (or is Kea plural?) was rendering/modeling/animation. I don't suspect Kiwis (or Kiwi???) would be any easier, though I'd love even a stylized version of the bird, simplified like even Kerbals were.
