How do you find making more complex assemblies in CadQuery? For example the type of mechanism that would use a Scotch Yoke and might have levers triggered by it or similar (just trying to establish a level of complexity and relationships)
6:20 A question about the falsification: How do we know if an experiment is open to falsification, that has not yet been falsified? And If an experiment is falsifiable, which we know because it has been falsified, doesn't that make all falsifiable theories false, because they have been falsified?
The falsifiability criterion, essential to a scientific theory, means a theory can *potentially* be falsified by evidence collected from empirical experiments, meaning experiments that compare a theory to nature. This does *not* mean all theories are false. It means all valid theories are *open* to falsification by means of contradicting evidence. Among scientists, calling a theory unfalsifiable essentially means the theory is not scientific. Only theories open to falsification, but that resist falsification, are regarded as science. Reference: www.techtarget.com/whatis/definition/falsifiability I hope this clarifies the issue, and thanks for writing.
@@lutusp I thank you for the reply but I worry that my question hasn't been fully understood. I literally mean, how do I "prove/know" that an theory is open to falsification / able to be compared to nature?
@@omerkaya545 Identifying falsifiable theories is easy -- one simply asks, "Can this theory be proven false in a practical experiment?" The classic example, widely quoted, is to say, "All swans are white." Seeing white swans proves nothing -- it only confirms our assumption that the theory is correct. But seeing a black swan instantly falsifies the theory. The point is we have a practical basis for falsification, one that can be compared to everyday reality. But -- very important -- we must be willing to look for contrary evidence. We must be willing to search for a black swan. Someone unwilling to search for contrary evidence is said to suffer from "confirmatiton bias." Someone ready to look for a falsifying counterexample is called a scientist.
Indeed. A long, long way from the Apple ][ - many thanks for your various videos. Incidentally, I just ordered and received a Raspberry Pi 4B - only to find that, unlike the earlier models, the 4B uses the miniature HDMI connector (which I didn't have to hand...).
You are most welcome! I bit the bullet and acquired some mini HDMI adaptors for my various Raspberry Pi models, each of which fills some niche role -- like controlling my 3D printer. Handy little computers -- and they put the Apple II to shame!
Excellent tutorial.
14:51 not in psychology or psychiatry. (to your credit you mentioned that those exceptions.)
The mind is not part of nature. Yet nature is only knowable via the mind.
Great tutorial, from zero to something useful!. I'm new to CAD and this has been one of the most useful tutorials I've seen. Thanks a lot! Also kudos to the developers of SolveSpace. There's some very fine programming there (the executable is 6 mb!). That's some old school fine programming there.
Thanks for watching and for commenting! You may be aware that I favor free, open-source programs, and SolveSpace is one of the best of that breed. Stay tuned for more videos in the future!

Thank you for this great instructional description of SDR, Paul. It is an extremely valuable resource in a subject area that can be pretty thin! When I go to your SDR website I just a blank screen (no error), however. Thank you!!

Hi! With step and rotate you ended up with 1 DoF. I've checked and it seems to be the angle by which the elements are rotated when stepping. Is there a way to constrain that so that it is fully constrained?
Hi -- without a context, without a diagram, it's not easy to identify possible reasons. Sometimes the menu item "Analyze" ... "Show underconstrained points" (Shift+Ctrl+F) can help. This feature lights up points that aren't properly constrained. I hope this helps -- thanks for writing!

What a nice video ^^ thank you
You're welcome -- I'm glad you liked it. I'm planning more of the same.
thanks. greetings from Chile. i can use this device in a Macbook M1? i need a adapter to usb - usb-c?
This link seems to show how to set up an rtl-sdr on a Mac: ports.macports.org/port/rtl-sdr/ I don't have a Mac so I can't be sure, but it seems to be true. I hope this helps.
Please call it "rtl-sdr blog v4", rtl-sdr is the hardware driver, and "v4" alone is meaningless. The page selling them is "rtl-sdr blog". Internally it have upconverter(similar to ham-it-up) for HF, and tuner/down-converter with filtering to isolate stuff to a analog low frequency(single digit MHz) signal. As in it's a full analog radio frontend going to a analog to digital converter. The rest is ADC+digital down-convert that can be looked up online for the specially interested.
I think eventually these devices will evolve past requiring two distinct phases to cover the frequency range they do. But at the moment this device produces a more efficient match with typical antennas than other similar devices. It's easily distinguished in side-by-side tests. Thanks for writing!
This is one of the best videos of its kind that I've seen. Great job, not so much the SDR part, but the general radio part, which of course is important to understanding the purpose and function of SDR. Thank you for a great resource for up and coming SDR and radio enthusiasts. .

Good video. You have a voice that is relaxing to listen to.

Absolutely agreed with you ! Freecad is a mess unfortunately. Just discovered SolveSpace today, and I'm absolutely excited !
Greetings. Regarding the face-off, I fed your exact questions into ChatGPT 4o and got the following responses: 1. for the bank loan, it wrote the following script: principal = 10000 monthly_interest_rate = 0.01 monthly_payment = 100 months = 0 while principal > 0: interest = principal * monthly_interest_rate principal = principal + interest - monthly_payment months += 1 if principal < 0: principal = 0 months and ran it for about a minute before halting, end explained that the payment only covers the interest and so will never be paid off. 2. for the descent problem, it correctly identified that water would be ice at -100 degrees, and so the descent rate would be 0, or very slight depending on any thawing of the ice by the weight. 3. for the murder problem, it answered as you noted. i then followed up by asking it to define murder and re-evaluate its answer. it provided 2 possibilities based on the definition: a. there would be 0 murderers left if the policeman acted lawfully, i.e. in self-defense or part of his lawful duty. b. there would be 1 murderer left if the policeman acted unlawfully. i'm not sure these shootouts tell us much, as it can depend on whether the model has been exposed to the scenario in its training. although, the follow up of asking it to define murder and re-evaluate seems to indicate some ability at logical inference..
It's interesting that modern chatbots still have a hard time with the bank loan. And it's instructive that none of them (so far) ask whether the payment is to be applied at the beginning or the end of the period, the two classic payment schemes. Thanks for writing!
I remember years ago reading something about fluidic intelligence. That is, how swiftly one APPLIES their intelligence. My IQ is high but as I always said, I never trade on it because it's an outdated metric. More accurately I say I have a large hard drive but a perfectly normal processor. I can store and recall large amounts of information, but I'm terrible at playing chess, I never remember the rules of euchre and even when I do remember HOW to do something, if it requires quick calculation I'm rubbish at it. I really enjoyed the tool analogy because I don't collect much in material goods but I do own a lot of tools, which are only purchased using the Amish method. That being, will I need this tool, will I use this tool, will it provide a result? Or would it be cheaper to borrow. I use my tools for car repair, home repair, electrical and HVAC repairs. But I haven't bought a framing nailer; I only frame things occasionally and get by with framing screws. Doesn't justify the cost. In any case, I enjoyed this video as a dose of humility. I am a shaved ape that knows how to operate a motor vehicle and power tools and make somewhat intelligible grunts. I will live and die, and I have and will have seen certain great leaps in our society, but what is to come none of us can fathom. Thank you sir.
Thanks for writing and sharing!
Hello Paul, thank you for the wonderful video. I really liked the two dimensional chart (intelligence vs rationality). This is a well-prepared video with good examples. Best regards.
Thank you! I hope people understand my reason for downplaying intelligence in and of itself, in favor of its applications. Thanks for your useful feedback!
I really like the way you explain that radio need the internet to work, but in fact it is the inverse. Been saying it for years.
Thanks -- like you I've been trying to persuade people that there's more to life than browsing. :) I appreciate your support and thanks for writing!
Thank you Paul, great video 👌
You're most welcome, thanks for writing!
This video seems well organized, clear, and thorough. Thank you. Though if there's anything of importance that's confusing or left out for noobs I'd probably miss it because I already know too much about RF, (if that's possible.) I built my first tube transceiver kit in '63 at age 13. I don't talk much on the radio. I experiment. BTW, I often use the SSB trick to copy weak AM signals. Sometimes it makes a great difference, sometimes none at all depending on the reason for the hard to copy signal. I live in Boulder, CO only 60 or so miles from the WWV xmitter site, but at that distance, and me being set back a bit behind the foothills I'm at a bad distance in a very bad location to receive any but the WWVB signal. Thus my use of SSB to copy WWV on 5 MHz. It seems silly that I have a hard time copying WWV when the rest of the USA has little problem, especially since I actually sometimes do work for NIST. I'm going to do a little building project and give a high Q mag-loop with a tuned pre-amp and a narrow-band filter a try and see how I do. Again, thanks for the video.
Interesting projects -- thanks for writing!
A very nice review. I am at least two or three decades behind you in age, but I am of the same type - I love building things with my hands, whether it is cars, planes (yes planes), radios or computers. As for Linux vs Windows, I think they both have a place. I use Linux for technical work, and windows for casual stuff like watching movies. What bothers me is a new generation of engineers and computer scientists who only know Windows.
Yes, complete agreement about Windows, in particular because Microsoft is aggressively pushing ads onto the platform and doing all they can to prevent their removal. Thanks for writing!
Thanks for the tutorial. I had to pause many times and rewind but I was able to get a part modeled I've been wanting to do for awhile. The cup example was good, I enjoyed that as my first entry to cad. I like solvespace, it seems fairly barebones but it works!
That's good news! Remember that CadQuery (mentioned in the video) may help you deal with more complex projects as your skills increase. Thanks for writing!
Thank you again, Paul. I tell my kids about a guy I heard of, who went opposite of everyone else and made a world of it. I drive a low-option stick car, do all my own repairs, got my ham license in 2015 and my first RTL-SDR a few years ago. And I love Linux and HATE Windows like poison. I'm eager to try an SDR program that isn't Windows-based. Always look forward to your videos!
Thank you! I think stick shifts' days are numbered, unfortunately. Thanks for watching and writing!
@@lutusp Not in the UK! Though I suppose EVs may change that. Thanks for the video.
So much information in there. Thanks to you for the work put in and thanks to the algorithm for recommending this to me, i guess.
You're most welcome, and thanks for writing, especially about the algorithm, which I find mysterious and inscrutable. :)
Thanks for this great video. Loved watching it. My first steps as a ham in SDR was by buying a flexradio the flex 1500. And loved it very much. The only downfall was that flexradio stopped supporting it, so one day in the future windows update will break the system. That is the main reason why my next radio must be open source and why I indefinitely switched to Linux. Running an Ubuntu based distro and starting again in SDR. One comment about your video. There is another advantage of FM in favor of AM. In AM, since the Amplitude is chancing you can get LFI (Low frequency Interference). That is that an audio amplifier can behave as a simple crystal detector and you be audible over a speaker system our an old gramophone. Since FM has a more our less stable power output it is more friendly in overpopulated areas as in my country The Netherlands. Just want to say love your video and have subscribed to your channel. 73 de PA5MC ... -.-
Yes, I knew about the amplitude advantage of FM, but I decided not to try to explain it. :) I was worried about leaving too many viewers behind in the more technical sections. As things stand, there's quite a lot of heavy lifting compared to most RUclips videos, but I wanted people to get a peek behind the curtain, so to speak. Thanks for writing and ...-.- !
Thanks for an interesting video! A fascinating thing I’ve seen people do on RUclips with SDRs is receiving image data from weather satellites, never done it myself but always wanted to try.
Yes, I considered adding this, but I realized people would need a special, somewhat expensive circularly polarized antenna, so I decided against. But it's entirely feasible. Thanks for writing!
Very good & interesting video, many thanks! On my channel there are a few first try SDR setups for SW. 10 May 2024. I (1955) also had, in the very past (1960's-1970's) a very limited budget when I wanted to do this hobby, radio.
Thanks!
For God's sake. What is this penguin + r key?
Sorry, I can't figure out which key you're describing. If this is still an issue, perhaps you could give me a time in the video so I can see the problem for myself. It might be "rectangle", which uses the R key. I hope this helps.
@@lutusp At 50 minutes into the video, when I'm trying to replicate the drawing, there's always an error when I do shift+l, exactly at that moment it also appears in the top left corner of the video saying to type this combination of a penguin figure + r and I couldn't associate it on my keyboard, maybe it is the cause of the error?
@@lutusp But anyway, thank you very much for your attention, I'm just starting out in solve space and I'm already learning a lot from your videos
@@natanaelmelo9481 Okay, I figured it out. The "Penguin+R" is actually my pausing the screen recorder, it's not a SolveSpace command. Please disregard it and wait for the next actual command. And just in case there are more of those, just ignore any "Penguin+characteer" commands, they're not for SolveSpace. My screen recorder has its own commands, and I sometimes pause the video screen recording to catch my breath. The keyboard recorder dutifully records those keystrokes -- I'll have to think of a way to prevent that. Anyway, when you see the penguin, just ignore those keystrokes. I hope this helps.
@@lutusp lol ok, my friend, thank you very much, now I understand. As for the error that was appearing, it was resolved by limping a box (force nurbs surface to triangle mesh)
How do you Chamfer/Fillet in this program
Unlike my now-favored environment CadQuery, to fillet in SolveSpace you need to deliberately put rounded corners into your design. This sometimes means changing your approach to a design. So, instead of simply drawing a circle and extruding it using Shift+X (no chance for fillets), to get fillets you would instead change drawing planes, draw a half-cylinder shape *in profile* with intentionally added fillets, then rotate the profile through 360 degrees with Shift+L to get the same cylindrical result with fillets -- fillets you added in the first place. In other words, you must add explicit curves at corners to get fillets -- there's no magic button-press or explicit command as in my CadQuery examples. This is one reason I'm now more in favor of CadQuery than SolveSpace. There are other reasons, this is just one. See more about CadQuery at this time position: ruclips.net/video/blkjW0JauX8/видео.html I hope this helps, and thanks for writing!
Thanks a lot for this useful information! Coming from Openscad and just discoverd CadQuery!
do you know if there is a way to pad/extrude a solid between two different sketches (I think SolidWorks calls this drafting)? An example would be a circle with a thickness of 1mm transitioning to a square with a thickness of 1mm across some arbitrary distance. I dont think it can do this, or at least I certainly don't know how.
> Do you know if there is a way to pad/extrude a solid between two different sketches Here's an example: imgur.com/gallery/QFu65j8 It shows three versions of two solids, one local, one imported, that overlap -- with different colors so they can be distinguished. The images show union, difference, and intersection. Again, one of the images is locally generated, the other is imported from another SolveSpace session. The same result can be gotten for two solids, both imported, into an empty parent SolveSpace session. In fact, in my assembly example in the most recent video, three arrows all overlap with one another, from a separate SolveSpace file, and they get along fine. That could have been three unique solids, all from different files. I hope this clarifies how this works, but if not, please ask a more detailed question.
@@lutusp Thank you but i meant more like a tube that changes cross-sectional shape as it progresses.
@@BAD_CONSUMER Okay, but what would this have to do with an assembly? Since what you describe could be performed in one SolveSpace script? An assembly would only add complexity with no compensating advantage. Also, I would need to see either a picture or an equation to know what you mean in a clear way. Here's a circle becoming a square: imgur.com/9baW1kP -- only because I can't figure out what you're trying to describe. I hope this helps.
Please please make more videos!! CadQuery ... Also you probably already know about Openscad but i thought to mention it if you dont.. thanks again for very good videos.
Thanks for posting! Yes, I'm planning to create more CAD/CAM videos. I know about OpenScad, but I need to get more experience with it, see if it's as easy to use as CadQuery, find out how many export file types it supports. Again, thanks!
You saved my hours of effort with just a four-minute video. Thanks.
You are most welcome! I'm glad this video is reaching the right people.
Great video as usual. Also good to know about FreeCAD. I was looking for a complement to SketchUp, I’ll keep searching. Sometimes I want not just to create a 3D object, but I want to emulate movement before send it to a CNC or a 3D printer. But CAD is a bit pricy. Have a great day!
Haha totally agree on Freecad. I'm an FEA/modelling engineer with 10 years experience and I confirm Freecad is by far the worst CAD program I've ever used.
Thanks for posting! It's always nice to hear from someone with the same awful experiences. :)

how to rotate a drawing in solve space with the mouse
It depends on how you mean "rotate". But try holding down the Ctrl key and right mouse button while dragging the mouse for one kind of rotation. Then try pressing the Shift key and right mouse button while dragging, for another kind. I hope this helps.
@@lutusp Thank you very much, it worked
@@natanaelmelo9481 You're welcome. Some SolveSpace users have complained that the rotations aren't intuitive, but I think over time it gets easier.
The biggest problem I know so far about FreeCAD is filleting irregular shapes and topological naming problem. How does Solve space do in these two areas?
To be direct, SolveSpace's filleting is less robust than in FreeCAD, and AFAIK the TNP has the same status -- it's not directly addressed or mitigated and is only less an issue because SolveSpace's projects tend not to be as complex as those in FreeCAD. I would be happy to be corrected about this view, but it's to the best of my understanding. The issue in both SolveSpace and FreeCAD that I find most annoying is the fact that you cannot change an element from which other elements spring without destroying the entire assembly. That would require a level of code robustness that neither program possesses at this time. The main reason I prefer SolveSpace over FreeCAD is that the former is less opaque to a new user. There are times with FreeCAD where I have no idea how to take he next step and the documentation doesn't help, or a feature isn't robust enough to accommodate what one might call s common-sense approach. Thanks for writing!
