I got nerd sniped by a great comment in a previous video. The idea was to make some kind of device to let blind people perceive their surroundings. The specific suggestion was to make some kind of a vest. Ultimately I ended up making an iPad case that uses the sensors in the iPad to perceive the surroundings and communicates through tactile feedback via a special hand grip. It was a fun project and turned out pretty neat.

@David McG damn lmao
@A T You’d sell out to women in a day.
have one controller for ur right hand and one for ur left. if something is on the right the right hand pins and if its on the left the left pins go.
"and it uses cell service, it's super..." "buffering... Please wait." "a'. r'. blip. -r reliable." Oh, and cell phone jammers cost $75 or less fyi.
Hey what about solenoids? Compact, sensitive, precise enough, cheap, jellybean parts driven by transistors. Maybe somewhat power inefficient but I don't think you'd need whole lot of actuation force.
It's not usual that such high quality content gets published this frequently. Thank you.
Yep this dude does not sleep.
@キトアカタカシ hey hru
Facts
Unusual*
This could be adapted into a smart cane for the blind as you wouldn’t need a screen (if you could manage to separate the idar )... so much potential as a real product
@Loki Averro what is your problem with someone giving some ideas?
I'd say glasses that are just sensors and on the sides you put those protruding buttons on the face side, then make them express closeness and direction with placement of the buttons
The better option is have the camera as glasses that the blind person puts on and have either a glove or a small stick as the indicator of what is around you.
Can get tactile response or audio response
Father to a blind son 6yrs old, turned blind 1,5yrs ago. He “watches” (listens) to his iPad regularly. Have been following your channel but this one I had missed, came up as a recommendation. People like you (and your supporting wife) gives me and my family hope that with tech everything is possible! And to all of you saying that a cane still is better, no, not to a kid that also wants cool tech! Thank you!
My late father tried to do something similar to this 15 years ago. The final objective was to help blind people, but since he worked in aerospace, the first prototype was to have a warning system for astronauts so they could "see" on their backs with feedback through a vest. It never got past the part of cheking sensitivity, kinda like you do at 5:15... But yeah, it brings me memories.
rip daddy fernando
Very interesting.
Dude, I sponsored several engineering student teams to do something similar to this 10 years ago. I stuck with an array of tactors (pancake motors) spaced 2-point-discrmination distance apart, and gave each tactor 3 bits of "depth" using PWM and current control. Note that a typical vibrotactile response scopes to only 8 JNDs (Just Notable Difference) so 3 bit depth just about covers what we can hapticly perceive. My initial designs were like yours, which morphed into a different form factor. According to my physiology research, I figured I could get a 64 tactor array. Not much but my form factor theoretically pushed the performance of that significantly. Sadly, this is one of my main back-burner projects that has not yet completed to a decent prototype stage. Sigh.
what in the fuck
“How to Shoot Video that Doesn’t Suck” changed my life honestly, good pick
yip yippity
Hi Daniel! I love your content! Keep up the good work.
HI MANNN
I did not expect to see you here
Hey Daniel love your videos!
As good as these videos and projects are (and they’re phenomenal), your wife takes it clear over the top!
Last video I haven’t watched... I don’t want it to end. Very cool concepts, very in-depth, informative, and funny! You seem like a really chill dude that loves making things with his hands. I’m a quality engineer for a CNC manufacturer and some of your videos actually helped me understand our laythes and HAAS machines a littler better. I don’t work with them, only the end result and tons of paperwork, but they gave me a pretty good insight. Thanks! Now make more videos!!!
I love how the top screen of the monitor layout always has some funny Amazon product on it. Makes the coding moments that much better.
This is awesome, I would love to see hydraulic operated pins so you could extend the pins as the object gets closer, it's alot of valves but you could end up with a reverse of the "pin art" toys.
Ah man, my blind friend is gonna be so happy when he sees this!
Lmao!
💀
Lol
"Sees"
I cant even begin to comprehend all of the engineering that went into this project.. WELL DONE
This was my favorite of your videos yet, I love projects that have real world application, help people, and/or functional.
I work as wildland firefighter and I think a guided missile style fire suppression device would be pretty cool. Especially if it could also be used to plant trees in hard to reach areas.
Your work on this channel is absolutely incredible. Thank you for being so amazing
He’s like a combo of “tech ingredients” and “Applied science” all packed into what seems to be a 30 year old Mark Rober. Can’t get enough!!
I thought he was 20
@Agent Smith • 2 years ago • edited 22 and married? no way
Maybe some MacGyver.
He's like a young Dean Kamen. Would be awesome to see him and Mark Rober do something cool. These are the types of people that with the right funding, they can raise the bar for society.
he gives off elon musk vibes too lol
This is genius! I can easily see future in this thing with little changes like.. no screen, one-handed and analog buttons. This could actually be a thing.
I’ve had the idea for pretty much exactly this design for years...so freaking cool to actually see someone build a proof of concept. Always felt like it would be a great phd/research funded project since it has the possibility of benefiting humanity like you touched on. Love your channel!
@Nico Nico Except the stick wont tell you about head high obsticals in normal use. The stick is also distance limited to roughly one stick length. A future version of this would make an excellent compliment to the stick by giving roungh information at greater range that the stick can be used to gather fine detail on.
The stick blind people use works better, is cheaper, faster,never runs out of battery, has better feedback ( lidar and low definition tactile"screen" wont be able to tell there are stairs, or a pole....)
Honestly, he should reach out to a university to collaborate, see if he can get his name on the paper too. Increase the chances of it being made a product. Could he actually get a PhD that way? Wouldn't surprise me if he had one already.
You make a lot of cool stuff, and this looks incredibly useful
I'd love to see version 2.0 of this. I've wanted the same sort of thing
summary: this dude is insanely smart
@Drained you couldn't do anything remotely close to this lol
@Drained you just gave up to everyone pointing facts at you lmao
@Peasant what's interesting if you watch enough of his videos, he uses essentially the same process and manufacturing techniques each time. He's just solving different problems with the same skills.
taking twice the space
I would have just made a bulky servo setup
I found this video by chance and love it, the feedback is an interesting design I really like the handle idea though would a constant pressure on the hand be easy to ignore. Would a “rumble” feature tried (Similar to a video game controller feedback) that could fit on the hand or as an accessory like a wrist watch or necklace?
What about low electrical shock instead of pins? I imagine you could increase the resolution and make it more compact.
The s20 has a interesting sensor where it can detect where things are in the room at night. It was a time of flight camera and it worked really well detecting how fair objects are. I'm so sad it's not in the new s21.
If you had a hemisphere camera, that could do some of the overhead warning a bit more clearly. I really like this prototype/concept. Is it worth developing further and then patenting?
I swear this dude has a PhD in Mechanical Engineering, Electrical Engineering, Computer Science, and Mathematics. My boy's wicked smart.
@Christian Blaze Blank He taught himself vector calculus and linear algebra on youtube? Doubt it. What he does is so much more complex.
@Coffee Cup Studying I'm actually an electrical/computer engineer and can guarantee I couldn't do any of what he does haha
@Mikko Rantalainen Right. I agree, it was an exaggeration, I was just pointing out how impressive it is that he is skilled in so many of the different engineering disciplines.
So obviously having a PhD in all those things was an exaggeration, but to all the people who are saying, "You can do this without formal education by just getting your hands dirty", I could not disagree more. Being a self taught engineer will land you somewhere in the Michael Reeves category at best. You can still build really cool stuff, but your ability to really go beyond hobbyist projects is limited. If you watch any of this guy's videos, he is using vector calculus, differential equations, and linear algebra to solve incredibly complex problems and I guarantee any "self-taught" engineer won't have a clue how to do any of that. What makes him unique is being able to know how to actually utilize his formal education in practical applications. He's a "get your hands dirty" type of guy but with the skills of a highly trained engineer which allows him to make the most complex builds on youtube.
@Nuhad What is more fraud to me is someone paying their way through a school taking classes that could have zero implementations in their work environment then expecting a company to come out of pocket to get them up to speed in the real world. HR hiring and training is one of the most expensive costs a company can make. Even more so in the engineering world because mistakes cost materials extra time and labor, and some times product delays. In the engineering world, and the drafting world. It is a team effort. So coming fresh out of college can hold the team back, and cause problems if not overly supervised. Having a incredible understanding of the industry, the product stack and work flow, as a test tech or assembler can go a long way into creating a faultless product. Most people can take up some form of drafting in high school. So the only thing college will teach you is physics and math on paper. Which does not always mean it will be correct off the paper. I’ve came across more than a fair share of engineers that, while understanding workflow in a program, lack common since and have severe over sights in application. Matter of fact I specifically remember having to stay over thanksgiving and work because a engineer messed up a top plate for a prototype demo that was being displayed after the holidays. He spent 3 days on it sent it to a partner to get CNC’d and it was all jacked up. I had to break out the drill press and some other shop equipment and go back through and correct his mistakes while sacrificing my holiday. He could not comprehend how it was wrong and was so wrapped up in his math that was wrong because of tolerances that I took him off the project and put him on something else because it was so time sensitive. Looked good on paper, but paper does not me jack. He also projected his measurements incorrectly. Another example engineer tasked with designing a label. Label was good. Looked ok. His first project. He sent it in and ordered it. Came back wrong color. 🙄 All because in the title block of the print he put green. Not understanding that that is such a wide term with so many meanings in color. He should of listed the hex or the rgb code he had on the print in DS CATIA. Little mistakes like that cost money. They are over sights that always happen. Working your way up in the field can teach a understand of these problems. Reading correct Prints in manufacturing can lead to a understanding of the standard the company uses, and so much more. On top of knowing how it comes together it boils down to a piece of paper does not mean crap until you learn the skills and can apply them to the job at hand. I’m of the personal opinion that they should not give a engineering degree or any degree just for being able to answer the square route of four. Our schooling system is incredibly flawed, and as much as I was proud of obtaining my position with my own intellectual prowess, and willing to apply learn, and listen. I still went a head ran through the system years later and got my shiny piece of paper that had almost no relation to the skills my company actually required. Being able to do the job is more Important than college otherwise you are leeching off people, and not a productive employee.
You might be able to raise the resolution by using a pneumatic system that controls airflow to each individual pin, in addition to this you can move each pin much more precisely.
Great work! Maybe next version could use hot/cold representation on fingers (for hihger resolution) instead of pins and actuators.
great video! the kind of technology that will definitely help humanity! great job explaining your designing processing. As an engineering student, I found it very enjoyable watching how things is made and the process of debugging, like what you did in the pool table game.
Excellent idea! I once heard of a research project where they used vibration-motors from smartphone arranged in a belt to tell you the direction in which to go. They would let the people walk around with it for a longer time (1 or 2 weeks) and continously lower the intensity. At some point the vibrations where so faint they could no longer be picked up conciously, which is akin to giving you an extra sense. I would probably try a newer version with something like this. And while you're at it: IF at some point Galileo comes online it would provide you with precise enough data from your surroundings. Augment that with information from a Google Glas, run optical flow on the video picture to get an estimate of collisions about to happen... That could work pretty seamlessly.
Hey, as an engineering student, your workshop and ideas are really cool to me! I think it’d be nice if you had a video walking through your shop/tools, explaining what they’re for and how you went about building such an impressive shop! And, it could be a nice low-effort bit of content in-between more difficult projects. Just an idea!
Jaden my college provides a limited membership to a local makerspace, and it’s totally worth it if you’re willing to put in the time. They had so much stuff there... I could literally learn to forge if I wanted to pay for it. It’s absolutely a mechanical engineer’s dream.
Agreed. I just finished college and I'd love to have a proper workshop one day but tools are expensive. I think for now I'm gonna spend money on a Maker Space membership instead. Most of them have the basic tools and a lot have CNC machines/3d Printers/Laser engravers and more.
@benson kwok I'd definitely recommend Adam Savage's one-day builds on the Tested channel; he spends a lot of time talking about the tools & processes he's gathered over the years. Also check out This Old Tony if you haven't!
Please!
Yes, please.
It's still amazing to me that people in this day and age can just build anything their hearts desire...
Eh, I'd argue the access for people to build anything has been diminishing as technology progresses. It requires increasingly specific (and expensive) machinery to make things compared to say the middle ages where you could make all your tools from scratch with wood iron and fire. Case in point, this guy dedicates a lot of his adult money tooling his workshop, as he said. And he's not exactly average in terms of wealth, much less on a global scale.
@Killertiger Gaming Learn how to master CRISPR and you betcha.
Can i build a cat girl
Awesome video! Looking at this made me think - would it be possible to switch from mechanical sensor to sound. I imagine it like this: every fraction of a second a set of notes is played, representing what lidar sees at this frame, from left to right. This way note tone can represent height of the object, tone volume can represent distance from the object (louder = closer), tone length (if even possible to distinguish in such a small time) can represent width of the object, and spacing between notes can represent distance between objects from left to right.
You are an inspiration for when my motivation to study engineering goes down. Keep up the amazing, funny and clever video. Never been so entertained ! An idea for a second proof of concept for a phone format: Couldn't you magnetically push a thin layer of magnetic sand (or a film) onto the hand of the holder to reproduce the image you are seeing with a much better accuracy ? Might be impossible to do on a small scale tho. I am just throwing an idea.
Please do more with this! revise, make it with more features, anything... so freaking cool
You should call it the "Eyepad"
@Jaky24 No. Skin conductivity varies by person and weather, and calibrating that would easily be anything between difficult and nightmare (for the user). Plus, in the right circumstances all it takes is 9 volts to kill a person.
@Stuff Made Here Replace the iPad with a camera (or two?) on a head-mounted band and one (or two) lightweight pads to hold to get even closer to that literal name? Wonderful idea - have any societies for the sight-impared been in touch?
@Stuff Made Here Wouldn't it be easyer to use small electric shocks instead of the pins to sense were you're going?
😂😂😂😂
Other versions of this(More involved ones) could have other equipment that's more discreet or easier to angle/manage(such as a haptic glove and a camera that can attach directly to the hand or head), so that it's significantly less awkward to use while moving around.
Amazing Idea! Thanks for this incredible content. Which do you use for the drawings in the tablet ?
Wow I had actually thought of that basic concept before ("seeing" through touch), I'd struggle to make it happen though.
The pins seems to function a lot like those in a lock. The mechanism also reminds me somewhat of those early rotating drum musical instruments.
Imagine being this intelligent. Your work is helping the world
Tiernan Wahl ofcourse
*the humanity
@Tiernan Wall ok troll
@Tiernan Wall proof or gtfo
@yo Alex what if it works you never know
This is awesome, we need more advancement in areas that are overlooked. You'd think we'd have a better solution for a blind person to see other than whacking things with a stick.
I've been thinking about a possible market-ready version of this, you can add some form of voice feedback too, this way you can combine this with image recognition, to inform the user of important things on the view. Maybe adding a button to send an instant image to a server to find and label objects and list them to the user via voice.
Love the video. I'm curious if you could make "Iron Man Gloves" that sense distance to the closest object. So you could wander around, using your hands to "feel" how far away things are. So, put one LIDAR sensor on each hand, find the closest distance, translate that to either heat, or vibration from a motor, or use pneumatic pressure to squeeze your fingers... Or maybe each finger gets its own squeeze, so you cal "feel" as you run your fingers across an edge.
While I'm not blind or vision impaired or anything, I feel like you really should get to work on this an make it into a real product. I can't imagine just how useful this would be to people.
This guy is like the family friendly and helpful Micheal Reeves
@Lucas Foster He's his own demographic and he knows it well.
I find him way more enjoyable, Reeves does some interesting (if totally pointless) stuff but he’s jus way, way too much for me. This channel is more my speed
It’s like if Michael reeves was actually intelligent
