Waterloo Ontario, University Ave. It's a wild neighborhood. But hey, it's home. Why are you talking like that? Uh, just, just filming a vlog. I'm trying to remember my, my
time as a Hacksmith intern. Whoa it's Hacksmith Industries. I've been watching these videos for years. Oh my goodness. It's the Smithmobile! Okay, Caleb, this is the Hacksmith Industries electronics lab. This is where you'll be spending a lot of your time. Your desk is right over here. Got everything you need. Got your laptop. Got some safety glasses. You got your lab coat. You should get suited up. We've got a project for you to start on. Okay. Okay. I will. Thank you Bogdan, sir. Alright. It's a Smith shirt, a note from Mr. Smith himself. Welcome to the team. I can't wait to see what kind of
projects I'm going to be working on. Now, Mr. Smith did say something about
augmenting human senses. When people think of Spider-Man the
first thing that comes to mind is web slinging, and climbing walls. But equally
as important is that spider sense. Wait do spiders even have a spider sense? It must be based on something. They can sense vibrations. So what, so can I. Anyway, in the comics Spider-Man is able to sense impending danger, dodging,
punches, and even bullets. However, we, humans just don't stack up. That is until today. You see sometime last year. Mr. Smith saw a project by a guy
who goes by Brain Devices. He used an ultrasonic sensor and the
vibration motor to alert the wearer of approaching danger. Using advanced Hacksmith Industries technology. I'm going to miniaturize the system and I might even
have spider senses in three dimensions. How cool would that be! But first, I'm thirsty. Hacksmith.store. Curse you gravity. We picked up this awesome
animatronic helmet. Its eyes adjust so it gives you that classic spidey scowl. Our plan is to outfit this mask
with multiple circuit boards that will be able to detect motion and then output a
spider sense "tingle" for the wearer. But it's not good enough to have the
whole helmet vibrate. The spidey sense not only alerted Parker
to danger, it also let them know where the danger was approaching from. Well, the entire helmet
won't actually vibrate. The sensor will trigger a buzz
in the location of the sensor that picked up the movement. So, for example, if someone dropped a
piano on my head from up above. The sensor on the top of my head would trigger the
buzzer in the same spot, alerting me to the danger from above. Makes sense? Now we need to make some
decisions on components. First we have the distance sensor.
You may have heard of radar. Radar sends out radio waves, then
listens for it to bounce off objects. It's then able to calculate
where that object is. This is a LIDAR, basically the same
concept as radar, except instead of sending out radio waves,
it sends out light. And this little guy can detect up to four meters of
distance with one millimeter accuracy. Now a sensor only outputs information. We need a micro-controller to both interpret and use that information. We've chosen the AT Tiny 85. It's nice and small. And it's powerful enough to understand I2C. The communication protocol used by the LIDAR. So to summarize the LIDAR is
going to measure the distance from the sensor to the object. Then the LIDAR will communicate
that information to the micro controller. The micro controller will process that
and send it to an appropriate output. And in our case, that output is a tingle. Now I just need to find
something that'll tingle. I've got a few ideas. There are some requirements. It has to be small, has to be wearable, and has to be safe. Now, this is a shock collar, and this is a taser. The taser doesn't sound too safe. Anyways. What were those instructions that Mr. Smith gave me? Don't do anything I would do,
and definitely don't do anything I wouldn't do. There's a little gray area. And that's where you operate. Hopefully this falls into that category. Well, here goes nothing. Okay. Not safe. Taser? Whoa Caleb...you okay? Doin pretty good. I was thinking like, what about using one of those
things that makes the cell phone vibrate? That that would be a better idea. Okay. Yeah, let's do that. Today was crazy. Probably shouldn't have tased myself,
but I wanted show that I was committed to the project, you know? Wanting to contribute. And contributed by learning shouldn't you shouldn't use a taser. We're going to be using a vibration motor. So simple. Why didn't I think of that? Well, I'm happy to make
a prototype tomorrow. It's going to be good. And I hope Mr. Smith is impressed. Picking out all the right components to build a
custom PC can be a daunting task is my motherboard compatible with this RAM? And wait, what about this graphics card? Things get complicated quick. So why not let the experts do it for you? Microcenter offers an online custom PC builder tool
to spec out the best PC for your needs that fits your budget. Not only that, the tool also ensures
compatibility between the selected components. If you want to do the research yourself, you can use
the brand new, online Microcenter community. It's a great place to discuss tech with other enthusiasts. Finally, if building just isn't your thing, you can have
one of the pros at Microcenter build it for you. Use my link in the description
below to receive a coupon for a free pair of Bluetooth headphones. Before I design and order the PCBs, I'm going to build a functional prototype to make sure
that all of these components work together as expected. I wrote a program for the AT Tiny
that will read distances from the LIDAR and make the vibration motor pulse differently depending
on how far away an object is. As you can see, the AT Tiny doesn't have a USB port. So, how am I going to get the program on there? If I can't connect it to my computer? Well, the Arduino UNO does have a USB port
and I can connect my Tiny to the UNO. Then I'll be able to flash the chip. Now it's called flashing because the process wipes
all the previous memory off of the AT Tiny and then uploads a new program. And then voila! It's now uploading,
as you can see from all this text moving by. I'm going to make my prototype on this
breadboard, because it allows me to easily connect all of our components. Micro controller, LIDAR
and vibration motor. Everything's plugged in and it
looks like it's working well. I can't think of a better way to demonstrate
than some action figure theatre. Just your friendly neighborhood Spider-Man. keeping an eye out on the neighborhood. Hopefully no bad guys started
approaching me from behind. Ah ah ahhh it's Doctor Octopus. I'm going to come and say hi to Spiderman. Hopefully his spider senses aren't tingling faster as I approach him linearly from behind. Da da da daaa. I've been found. I will retreat. As you can see the I2C bus between the LIDAR and microcontroller is working just as expected. I2C is super cool. Without it, this project would not work at all. It's a multi-master, multi
slave, packet switch, single ended Whoa whoa whoa...WHAT?? I2C stands for Inter Integrated Circuit Protocol. It's like a language that is used to
communicate between different components like our LIDAR and AT Tiny. The advantage of using I2C is that
many components can be connected and all communicate between each other. Each device sends and receives signals
over just two wires. For our project, the LIDAR breaks down the
distance measurement into a signal. That is sent over the two wires. The microcontroller is connected to the same two wires. This allows it to receive
the signal from the LIDAR. The microcontroller then looks up the
signal in a library to see what it means. There, you happy with that explanation, Mr. Camera Bossman sir? Can I get on with the PCB design? This is going to be the sensor board. It will contain the AT Tiny,
the LIDAR, the vibration motor. We're going to order a bunch of
these so that we can put them all around the helmet and get the
spidey sense working from all angles. Sketching this out really helps me plan what I'm going
to do when I hop into Altium designer. All the connections from this prototype need to be
represented as lines on this schematic. If you want to see the full diagram and all of it's digital glory, check it out on maker.io. using the link in the description below. With all of our components mapped out our next step is to hop into Altium Designer and lay out the board. I've put all the components close together as possible to keep this board very small. If you would like to see the layout of our board,
you can check it out using Altium Viewer. Another day in the can. Got to say that video team sort of annoying. Josh just kept on interrupting
me and asking me to take it slower. I mean, how do you make it onto
the Hacksmith's team without having a solid base of programming
fundamentals like I2C and flashing? Oh well, I had to bring it down to like five-year-old level
and bust out some toys to explain it to him. But tomorrow it's going to be a good day. I'm going to be designing the power board. And I got a special idea in mind for that. And I'm also going to get to build a bunch of the boards,
which is going to be pretty hype. All these boards need to get sewn into the Spider-Man mask. Now a rigid board would be uncomfortable
and would poke out of the side of the mask, but I did some digging and I found
out that you can order flexible PCB's. Can you believe it? So I went and ordered some. Now all that's left is to take these
boards and my bag of LIDAR's and AT Tiny's and put them all together. With great power comes great responsibility. This is my gift, my curse. Who am I? I'm Spider-Man. The AT Tiny and the LIDAR are
permanently attached to the front. Next step is to solder the vibration
motor onto the back of the PCB. Alright we have all of the components attached now, all
that's left to do is to plug this into a power supply and make sure that it works. If all goes well, you're going to
see this little light turn on and the motor will start to vibrate. If things don't go well, something might start smoking. With the boards completed and working, I'm ready to
integrate them with the Spiderman mask. Thankfully, Aunt May's a real gem
and she lent me her sewing supplies. I'm going to cut multiple
holes in this mask. So the LIDAR can peek through. Then I'll attach them
with needle and thread. It's all done. Now we're ready for some action. Alright. The system's complete. Oh my goodness guys, come on. We talked about this. I can still see you and I could
hear, but we're going to fix that. So I shall be wearing these earbuds
to blast some groovy tunes. And to deal with my ability to see, I'll be
wearing a blindfold for the whole test. Alright, now that I'm blindfolded and listening
to loud music, I can neither see, nor hear when and where these
balls are coming from. So they're going to
drop them one at a time. And I won't know which one
or what time they're coming. Hopefully the spider sensors will
alert me to both of those details. Got the reflexes of a dead tiger. Oh, come on guys. I don't even have a sensor on
the front that was just rude. The thing is the system's
working as expected. I mean, I could, I could hear the
thing vibrate has the ball was coming. I'm just a human though. So I didn't react fast enough. I was getting closer. So I think let's try a few more times and see if I can get this. Close. Air ball! Oh my goodness. Probably should've put
a sensor on my forehead. Alright, that was a bit better. I'm glad I was able to at
least block a few, but there is another way we can test this. Let's go for a walk. So as I walk forward,
I can feel it lightly pulsing. And I programmed it. So it pulses depending on
how far away something is. So I know there's a wall over here. Oh, it stopped pulsing. Nope. No, it hasn't. Nevermind. Okay. And..okay. No pulse is on my left,
which means I can go left. Now, if I go forward. I'm doing alright. Feeling pulses on both sides. And now I got to wait until this one
stops pulsing and then I'll know that there's an opening, like right over here. Alright. They're both pulsing. There's something nearby. No pulsing. That means I'm in a wide open space,
which means I have no direction. Ooh, dark alleyway. You wonder how I do in a fight. Though I can't dodge bullets. I can probably dodge
some slow motion punches. Owen over here has been training for a
month to prepare for this very moment. Bring it on. Well, my spidey senses are
telling me that I'm pretty tired. Like we're, we're done the test. You can go, Man. My Hacksmith Industries
internship has been incredible. I mean, I get to work on projects like this. This had a LIDAR, flexible PCBs, the whole works. I'm really thankful that Hacksmith has let me work with all sorts of interesting technologies and build really cool projects. Getting to know the team was great. Everyone works super hard to make these videos happen. I mean, there's lights on me because
someone put them there and that wasn't me, but they they're doing a great job. With this project, I'd say in the future, probably
would have spent a little more time fine tuning the programing so that I could react better to things coming at me. But that's the thing with engineering. You have to build something and fine tune it,
and keep on making changes, keep on making it better. And yeah, I'm really thankful. It's been a great time
here and I'm going to miss it. I am intern no more.
