I was 1/4 though the video and paused to write that you are a legend! You really care about passing knowledge to us and giving us tools to work independently. You are a selfless legend Sir!
Thanks for the lesson Paul! Always good to hear the math behind the problems. The teaching perspective of, "math is your friend and the solution, not the problem" is always very good to hear!
This is the second time I watched Lesson26 and it is better the 2nd time around. Also, I have watched Lissajous patterns made with a swinging bottle of sand. 🥳 Thank you.
I AM LEGEND of the CHALLENGE OF ALL CHALLENGES !!! This 80 year old codger with 2 engineering degrees made a floating potato chip. lol Unfortunately, I am not into recordingRU-vid videos, so you will just have to believe that my wife will testify that she saw it. This was a half-day project with a lot of missteps along the way, but persistence prevailed. Thanks Paul for another most-excellent lesson.
For the circle, I worked smarter not harder by using the ellipse function. BUT after seeing Paul's solution that would be best if a full circle is not needed. TY Paul. Suggestions for addressing 2 SSD1306(s)??? So, is that only a single chest bump or a Target lawn chair???
I used the .ellipse function from the framebuf library after noticing that the SSD1306 driver referenced this library. Just set the x radius and the y radius equal to one another and you get a circle instead of an ellipse. Maybe that's cheating? The key instruction: myoled.ellipse(xpos, ypos, 20, 20, 1) , where xpos and ypos place the center of the ellipse in the middle of the screen.
Challenge accepted! Well, kinda...I didn't use an RPi or OLED, but instead turned it into a tutorial on how to draw bitmap animations in C# for my channel, and used the Lissajous as an example. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-viIWlNfxffc.html
Thanks for the cool tutorial. I loved TRYING to figure out the circle homework. So I guess trying to fiqure out the potato chip in 16 lines or less should be fun as well. Math rocks I dont get it but I like it.
Here is the link to my new improved solution to lesson 22 and also some thoughts on lesson 24: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-2vtuvreFxzw.html
It is so pity I found your lessons so late and I'm not in schedule. As for circle, I used Pifagor's theorem to build circle as I didn't want to use math library. It has no so flat sides at each 90 degrees but it has some spaces at y axis at every 180. As for next homework, since it was posted 4 month ago I can put spoilers here :) It is lissajous figures. I draw them on old oscilloscopes in our lab at university. Will not watch next video until I finish this challenge.
I am legend. I found that the primitives text, rect, line, etc are inside framebuff that ssd1302 is importing. There is also an ellipse primitive and if you set both diameters to the same value, you draw a circle
Yes, the lesson 70 concludes the Raspberry Pi class for now. Next up, likely I will do a class on the new Arduino R4. That will probably start in a month or so.
Hey Paul, got a Q....how would I control an LED that's built into my microphone boom arm (The current controller is a small remote attached to a cable coming from the boom arm) I would ideally love it to be enabled whilst the microphone fader is up.....if that isn't possible a button would suffice
Hi Paul, Would I be correct in saying that if you started the x axis at 0 instead of at 5 that the circle would have been completely filled? Thanks much.
Hello Paul, Sadly, the raspberry pi is out of my price range. So would the Raspberry Pi Pico W work with the Raspberry Pi tutorial? i know theres a specific tutorial for that but i feel this is just more detailed
You can di a lot with the Pico, but the Raspberry Pi has resources that are missing on the Pico and Pico W. The Raspberry Pi has a full operating system, HDMI, USB ports, Camera port, Ethernet, and a micro SD port.. The Pico is missing those features. However, the PICO and PICO W are very capable microcontrollers. They typically are relegated to doing a single task. The Raspberry Pi OS can do multitasking.
I decided to try to do all the RPi lessons on my pico and I managed it pretty well (until the Pico W lessons started). I have posted my alternative solutions on my channel in case you're interested
Charlotte, I do not have a regular Pico to check, but Lori says it is available in the regular Pico. Did you get your Pico code from Pimoroni by chance?
@@keithlohmeyer I'm using the pico that came with my Geeekpi kit. I can't update micropython past v1.19.1. Maybe the problem is with Thonny. I'll just use a pico w until I get time to look at it.
Yes I was able to use the ellipse method with a regular pico. I was using the official micropython v1.20.0. I loaded that version from inside of Thonny on to it.
I retracted my full video and replaced it with just the introduction which shows the results. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-54MaW8i91Cg.html
Well I have folded up like a cheap Walmart lawn chair. I have no idea where to start without cheating. Since it look like a sine wave I assume trig will come into play. Look forward to your solution Paul.
Tune in for next weeks lesson. It is basically an old trick people would do on an oscilliscope. And it is easy enough to program up. Thanks for watching.
I hope you don't consider reading on these curves cheating. I didn't know the functional form to use so I read a bunch and then coded it. Got it running but I would like to make it not "flash" so much on my screen as I clear it out.
I am with you Keith.. I don't want to go look at other solutions yet. Still ahve not given up. I sure have learned alot. I ahve figured out how to show something like a potato chip, but cannot figure out how to make it spin.
Great assignment, Paul. Here's a link to my solution for Homework 26 (which also happens to be my very first RU-vid creation): ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-own896ac_5M.html
Now I have made my solution public ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-P3esd0ux5oE.html I wasn't clever enough to look ahead for the Lissajous hint. I plotted the potato chip, started it rotating around the z axis and then displayed the projection on the y-z axis. I think it looks the same, but not quite as simple (or as versatile). Thanks for the lesson!
@@paulmcwhorter yes, after I posted my solution, I noticed that Charlotte posted her results, but withheld the solution so as not to reveal how to do it. Following her lead, I set my original video to private. Here is the introduction which shows my result, but does not include the details of the program. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-54MaW8i91Cg.html
