Of all the Maker Portfolios I have watched today (all of them available on YT, I think lol) this is by far my favourite. What an incredible idea, I hope your friend gets to use this every day!
I built something very similar to this where I used a ultrasonic sensor that mapped its input value to a pwm signal for controlling a vibrating motor connected to an h-bridge. I used an arduino uno for the coding, but had issues with the consistency of the ultrasonic input. Its value jumped around so much that it was nearly impossible to get the motor to spin at a controlled speed. Any tips?
how about you just lerp it and clamp it. Or you can smooth the signal. You could even use the input signal (After clamping it) as a lerp parameter, and interpolate between min and max intensity that you want for your motors. I would also recommend having some kind of system in place to prevent small anomalies from triggering the motors. You wouldnt want a false positive to make the motors spin randomly at times. Easiest way to implement this would be to make the motors only trigger if the sensors have gone over a certain threshold for over a set period of time that could be of about a few ms. Dont go overboard with this threshold and delay tho cause we want to prevent false positives in low quality sensors, but we dont want to add too much delay or you might start seeing the motors trigger with a noticeable delay, which is not something we want. In a nutshell, map your value from 0 to 1, clamp whatever excess you might have, lerp between 0 and max motor speed and wait for at least 2ms of the sensor giving a positive signal before triggering the motors.
after seeing david eagleman's ted talk, i was intrigued by this idea as well! do you mind open sourcing it? would be great to start from somewhere rather than from scratch. I would love to create an open source version of this in future too.

Let's see Paul Allen's Maker Portfolio
I see it wasnt just me who got psychopathic vibes from this guy
Bruh

I was blown away to tears this project. Thank You for being a wonderful maker!

this is... this is... this is bloody beautiful. I am overwhelmed with tears
You already doing what many other tech nerds like me are aspiring to provide, amazing job. I wish you good luck in your future endeavors.
made a project almost exactly like this my freshman year of college 3 years ago for a design expo lol, very impressive

You could implement a smoothing algorithm that will remove the random spikes that the raw sensor data can output. Best of luck on your project!
Add an mean average by multiplying then dividing in the code and then combine that answer into a variable and use that in the if statement

You are a winner. Godspeed
that was really dope man
Carry on!
You are the Future!
Awesome Buddy! Congrats!

Amazing video!
amazing project Jake! congratulations
what a lovely young man. he would be a fantastic systems engineer!
such an awesome friend you're man
This is super cool! What were ur other stats/extracurriculars like?
Thanks for inspiring
Amazing!
that amazing
your a good human i can say that
At ur age you are alr doing something awesome like this, idk what to say i feel useless as someone who is abt to graduate
Brilliant 🎓
Woa, needed more information here. What was his feedback? Did you take the project further?
so nice
Did you go to RSEF by chance this year? Ive heard of a similar project coming out of there from my friends who went
Great 👍
Great project. Can you please share the code for this bro?
Wonderful invention, dude. How you got these ideas, Bro???
Make more stuff and post bro!
Why gave these portfolios spammed my recommended
how did your application go?
@Jacob Donnini Nice man~! I hope you make it!!!
Which engineering major did you pick up bro?
Electrical Engineering
I've really jealous about your skills, I wish I was as smart as you to build my ideas that could be even better than this, BUT I'M NOT :(
AM I? 🤔
Yes u r
Hello
Say : jacobo cuanto mas alto mas bobo
Really, you "showed" a blind person how to do something ? 1:16
are you proud of yourself?
you are making the world a better place
