I AM LEGEND! Although my label text was off a bit, I made a pretty good looking hygrometer. After I watch Paul's solution I expect to learn to fix the text position problem. I even did the math correctly! Thanks Paul for another most excellent lesson.
Sir, thank you for your dedication to passing knowledge on. My 12 yr old son and I have been doing your videos together along with you. It has been a positive, uplifting bonding experience for us. We have been thinking of a project that would apply to our home and was curious if you might do a series on a closed loop stepper motor to tilt horizontal blinds. We are trying to figure out how to retain manual wand control and the motor still know its absolute position so it can execute an automatic routine without going the wrong way. Something that has a LAN api. Thoughts? Again, thank you sir. In faith, Eric and son
And the best part is the priceless memories you are giving your son, that will last a lifetime. Well done! Might look at doing some home automation work after I finish the Raspberry Pi lessons
Sir,How u have approached for becoming a self learning programmer and developer using different technologies?? How do u filter the best content for self learning over the web of internet??
Hi Paul. Thank you for this tutorial, very interesting. I'd be keen to learn how to connect the vPython output interface with my website and display the digital readings live. Any sources you could recommend on achieving this?
The math for calculating theta was elegant but unnecessary if a for loop is used to define theta in the while True section : for i in np.linspace(5/6*np.pi, np.pi/6,100): theta=np.pi*(1-hum/100) Also, in the temperature script, using a for loop to define cylinder len in the while True section eliminates the need for the math. for temp in np.linspace(0,115,100): len=4.5*temp/115
I dont understand why you want to use intuition instead of just doing the math. The approach you suggest only works when the y intercept is zero. What I see is many people want to do ratios instead of a linear equation. Then they come up to a problem where y intercept is not zero, and use ratios and then get wrong answers. I show how to do the math, and dont understand why people want to try and solve problems NOT using math.
Thanks Paul! The Math behind this project is worth every minute spent here. It is certainly not for those not willing to "...Learn or die trying..."
This is really cool, by the way I really appreciate the math background.
"Math is the solution, not the problem"
Thanks again!
Another great lesson. I am beginning to understand the vectors and axes better now.

LEGEND!
I am astonished to see your knowledge of recent technology..Great lesson. Thank u.
Great lesson Paul! Things get little complicated but can't wait for another lesson. Enjoy your coffee!

Another great lesson. Thanks.
My pleasure!
For the direction of the vector for the arrow, I don't think you need to include the arrow length. Just the directional sine and cosines.
Thanks!
WOW, thanks! That is a huge encouragement, and greatly appreciated.
God Bless you Paul.
And may God bless you as well.
Sir,How u have approached for becoming a self learning programmer and developer using different technologies??
How do u filter the best content for self learning over the web of internet??
thank you for sharing ! sorry i had to leave the chat early today.

I'm grateful that you showed us the math and will keep viewing your series to learn more! I look forward to your lessons every week.
Radians or is that polar coordinates? That is an unpleasant flashback to a math class long long ago in a land far far away.
Two seperate topics. Radians are a measure of rotation. Polar coordinates is a system to locate points in space based on rotation and length.
what is the new RPI class be named/?
