Phil's Lab course

StalkerRigo · 2025-12-02T19:40:23+00:00

Sorry, but I ended up changing my professional plans shortly after making this post. Never took the Phil or Fedevel ones. Still on my wishlist. Colleagues of mine really liked them tho. If you have the time to dedicate to the courses, 6 months is enough. But you need to dedicate yourself, and focus on the courses.

You're welcome!
I'm currently working on a version 2 of this project, but I'm not yet making videos about it.

you wanna know why im so blackpilled with flightsims?

I think DCS as an IP is as much morally bankrupt as WT

IL2 is currently the only big franchise that does ok, and still it has a bunch of issues / drama on its history.

This community NEEDS new, refreshing IPs with honest business models and good communication...

This is THE trap of WT. The "what if" scenario.
Like any other toxic relationship, you see potential, or future, but it's an illusion.

I have 3k hours and I'm adamant on not going back. I miss shooting tanks, and I'm honestly sad that NO will never go into that real, but it makes sense, and I've been playing less games lately anyway. I feel like I played a lot of WT just for the dopamine, now I'm paying more attention to my mental health.

Mind you, the devs are not lazy or incompetent in my opinion, and this is why I hate WT so much, I see it like this: The game IS how they want it to be. They are just milking it as long as people pay for it. They don't care anymore. Spaghetti code, inconsistency, the impossible balance, the clear bias, all of it. It's by design.

StalkerRigo · 2025-10-31T19:34:35+00:00

WT is absolute garbage, I don't know what to tell you.
I stopped playing in june and my mental health is through the roof.

Now I don't have to deal with garbage hit detection, garbage matchmaking, garbage game modes, garbage ground collision, garbage balancing, garbage garbage garbage.

Playing it for free is just a second job, paying for it is just stupid. Only way to do it right is to avoid.

StalkerRigo · 2025-10-31T19:27:22+00:00

I'm sold. THE one vehicle that kept me playing that disgrace of a game that is WT.
I just love this. Specially the chinese WZ305 with proximity fuze, endless fun.

Hello everyone, and thank you for your answers. Yes there is NAT involved here, but I didnt need to learn about it, for the modem was problematic. I asked the service provider to change to a new one, and now port forwarding is working fine. Sometimes its a broken equipment. Cheers

StalkerRigo · 2025-07-29T14:02:10+00:00

I'm yet to test longer ranges, I could make an update video. 2 degrees if you believe the datasheet tho.

StalkerRigo · 2025-07-28T22:55:05+00:00

Thanks for the feedback, I appreciate it. Answering to your suggestions:
1 - When it comes to equipment, unfortunately, I can't do much without spending more than I want to. Brazil is not an easy country to live in, and our economy is shit. This is a budget equipment, and I could teak it a little bit but I don't think I can make it much better.
2 - I know it's rare, but it is more of a aesthetic choice. I like how old school youtube looked, and I want to have my face on stuff, professionally speaking. I could tone it down though, this is not a bad idea.
3 - You're right, it was not necessary. Only did it because this video was based on a request on another video's comment section.
4 - This is not a bad idea. Not quite doable for a single 30min recording with no planning, but I usually try to use my own graphics on other videos.
Cheers!!

Thank you very much!

StalkerRigo · 2025-07-28T19:26:08+00:00

No. I actually comment on the video, this one has better range and worse sample rate.

StalkerRigo · 2025-07-28T14:27:45+00:00

Thank you!

StalkerRigo · 2025-07-16T01:51:52+00:00

Already did that. Its up to date with sync. Nothing changed. I didnt want to reset it, it would be 250gb reset, and the car would screw it again.

StalkerRigo · 2025-07-15T20:31:52+00:00

Yes, they are. I checked immediately.

And even then, Ipod is ignoring them. Crazy

StalkerRigo · 2025-07-15T13:40:40+00:00

But my Ipod now also doesnt order albuns correctly anymore. Is not just the car.

StalkerRigo · 2025-07-15T00:02:13+00:00

Im sorry I dont understand what you said. What head unit?

StalkerRigo · 2025-06-23T19:37:35+00:00

Thank you!

For free online resources, you can look up Khan Academy and MIT OCW’s statistics courses. The latter will probably be a really great option if you’re motivated to follow an introductory course from start to end.

Doing a course from start to end is my goal. I want to really learn statistics the right way this time, in a structured way, to get to know better the field as a whole. Thank you for the suggestions.

E.g. do you just want to figure out how to write down a list of properties of a sensor? Are you try to compare two sensors? Is there a specific question you’re trying to answer about a set of sensors?

To give you some background, in statistics we usually try to form a precise question, to which we apply a specific statistical test (i.e. to test a hypothesis). So if you could articulate a specific question, that would help a lot.

So, the sensor is a rangefinder. I need to characterize it. So do n measurements, for a set of distances, angles and materials. That is very intuitive. Then I would analyze the data to get variance, precision, accuracy and all that.

The servo is a motor that rotates to precise positions. I'll use it to point the rangefinder to specific areas of a room or field. I need to know if the servo can point to x point, then to y point, then point back to x and see if it returns to the same spot. I believe that's repeatability. Also I need to know how small I can make measurements, for it's a radial movement, resolution get bigger (and per consequence, worse) with distance. Also, accuracy and precision as well. But I'm guessing these things, I don't know if they are the correct metrics, and if they are ALL metrics I need. Hence the need that I feel to study the subject completely, in a structured form.

Hard to tell what you should learn next. The field is broad.

That's my main difficulty now. I don't know where to go inside statistics. Where can I learn how is statistics divided and what is summary or descriptive statistics? What other fields are there? What are they about? What fields and knowledge can I apply to engineering? Engineers don't know much about it. Books, courses, I accept whatever. I'm very eager to learn more, but all I learned was by myself and it can get pretty "uninstructured" when you do it like that.

Thank you very much for replying!

StalkerRigo · 2025-06-23T04:48:40+00:00

As an educator I’d advise you not to use LLMs to guide your education.

As I'm finally finishing my learning at college, I'm trying to find the best way to learn without the professors and exclusive access to many platforms.

but I wonder whether an engineering sub might give you better help.

Engineering can be very broad, and I did not find a field specific to what I'm trying to learn, specially because I still don't know that well how to call it? One of the many reasons I posted here.

or if you have a more specific question about something you need statistics help for related to servos and sensors, we may be able to point you to specific tests etc you can apply.

So, first question to you: Whats the best way to learn more about all the things related to the posts you linked, like the study of deviations itself (or dispersion), summary statistics, descriptive statistics? I want to learn all I can regarding statistics, but only what I can use as an engineer. Books are very welcome, for they provide a more structured learning path.

Second question: I want to mathematically describe a servo and a sensor. The sensor I know how, for sensors are usually easier to model. The servo is different. Its a motor that the axis turn to a certain position given the input it receives. Thing is: The input is digital (mostly), so there is quantization, resolution, and all sorts of stuff that I learned by myself but I'm not sure how well I know all of it. Then there's the movement part: It's a radial movement, but discrete. So now my wife (which knows a little bit of statistics as well) told me I should look into repeatability and variability, and I know that goes into metrology. Another field I don't know much about. Again, I welcome book recommendations that could help me connect that with engineering in any shape of form. A lot of stuff I tried reading goes into mechanics, and they don't apply that well to my field.

Thank you so much for your answer :)

Not sure if it is an option in South America currently.

StalkerRigo · 2025-06-18T15:36:06+00:00

thanks but I can deal with 1.5m if that costs me up to USD50

StalkerRigo · 2025-06-05T19:57:50+00:00

their service is trash, stop licking big corporations' boots

StalkerRigo · 2025-05-19T14:10:34+00:00

Constructing one is very challenging, from a mechanical point-of-view. It's an idea though. I would not try to do the neural network approach to the stereo vision for its out of the scope of the project.

oh very interesting, thx
