Building a Smartwatch from SCRATCH!

[Music] what's up guys I'm Steven I love my pebble but they got Bob my Fitbit and all their servers are down I know that the whole rebel project exists and like I can still get some mileage out of this thing but it's already like three years old and this is a great opportunity to build my own SmartWatch so today that's what we're gonna try building a smart is a really really hard problem to solve it's packin a bunch of stuff into one tiny little that's supposed to throw your wrist and the thing that I like the most about my pebble is how flat it is well close it is to my wrist so I'm gonna try to replicate that it's gonna be really annoying and really hard but it's gonna be fun hopefully I get it to work now I need this watch to have bluetooth so I can talk to my phone and get notifications just like my pebble does so for that I'm gonna use this guy this is an ESP 32 it's the bigger brother of the esp8266 which is what I used for the glo time not only does it do Wi-Fi but it also does bluetooth and it also is like a quad-core processor it's a crazy it's super super powerful they're totally sweet is kind of big but I think we're gonna work around it I'll try and finagle stuff and get it all to fit nice and neat my wrist but this is gonna be my brains and it's also going to be what talks bluetooth to my phone despite the fact that this chip is so awesome it has one of the most annoying form factors ever it has pins going along the side top and the other side and they're also not space to fit in a breadboard so I can't just like easily plug this into anything that I have for prototyping I have to mill a breakup board I also spent a lot of time looking at different kinds of screens that I wanted to put and watch I really wanted it to be full color but all of the full color like modules that you can buy on Aliexpress sir Amazon or whatever are huge they're all mounted on to a circuit board already and they're just monsters I could be really hard to fit into a nice slim profile so we're going the hard route I bought an actual just bare screen module with like this crazy little connector on the end of it that I'm somehow gonna have to interface into this board I've never used one of these connectors before I've never used just like a bare screen module like this so this is gonna be interesting but the same problems with this I can't just like talk to this and test before you order boards so I'm gonna try and mill a breakout for my ears 32 in the screen right now so I can throw them into a breadboard and try and make an old Park [Music] [Music] [Music] [Music] these look so good and even with my hunkajunk milk that's awesome cool so now I'm gonna start out the SP 32 - this breakout along with the flex cable connector for the screen and then I can start like wiring stuff up and testing stuff out and hopefully I can get the screener on and boot the SP here we go [Music] [Music] I mean my breakouts these are such tiny little traces it took me like three out of three hours how long have taken me like 40 minutes I was exaggerating it took me like 40 minutes to solder all of these tiny tiny little connections this one is half a millimeter stroke and Ida saw her all those tiny little guys on there that was very very time-consuming okay without having a solder mask like the layer that traditionally green or what I like is matte black to actually keep your solder from just going all over the place it's really tricky even if you just look on this board there's a fair amount of solder that kind of worked its way up the traces and just kind of like what really wasn't supposed to know there were things all wired up and I can put it in my breadboard I'm going to try and program to the ESP make sure that works try and talk to the screen make sure that works and those are the main parts these are the two big heavy hitters and the watch this a battery custom circuit board that's it I think oh end then like a charger for the lipo I'm gonna do some kind of Pogo pin magnetic thing I'm not quite sure yet but we'll see see [Music] it works I finally got a program but I just have like a little blink sketch running right now just to validate that it works this is gonna be a lot watch so now that I got this working it's time to move on to the screen [Music] okay I'm pretty sure it's all set I got it all hooked up according to the datasheet and also the screen is really similar to one that Adafruit sells so I use that as a reference to kind of see what pins they use when they line things up all that stuff now is to upload the graphics test the Adafruit has for their library which is also what I'm using to drive the display and hope to god that it works but we'll see we'll see all right let's program okay good thank God oh I thought I wasn't going for a second all right here we go so now I just have to reset it Oh check it out look at that beautiful screen this is just the default Adafruit like graphics test oh my god I can't believe it works wow that screen is beautiful oh man connect it on a custom breakout board and the custom breakout for the SP oh my god I'm so stoked I cannot believe all this works well what yeah now I know everything I need to know to order the board's okay time to like take all this and just right into Kai CAD pretty much all these connections just not super messy like it is now oh my god that's so exciting wow I just can't stop looking at it that's gonna be on my wrist soon this is so fun all right the circuit board design is done I took everything that I did out on the breadboard that I knew for sure worked and I plopped in a chi CAD and I have this glorious glorious board it's really really small and everything is really densely packed and it's my first four layer board so hopefully I did everything right we'll see you when we get the board's back but that design is finished I send out to the board shop and I should be getting it back in like a week I hopped in a fusion 360 and I designed a case for the watch I'm super stoked with how it came out it's still really really slim so it's not gonna pop off my wrist a bunch then i open it up in preform and threw it over to my form - at work and i had a custom watch case just like that i printed it in grape row that's my personal favorite resin it's super strong it's easy to paint it's a nice matte finish i may not even paint it it looks pretty good just as grey but we'll see then I grabbed an old watch strap that I had laying around and I just kind of pinned it in I designed the case around the watch strap so I knew fit and there it is this leg actually looks kind of like a watch oh that's so cool I'm super excited about this so now that I have all the body made all I need is the guts to go inside now I wait for a week for these boards to come in and when they finally do I can throw all the goodies on there and put it into the case and program it and wear it it's kind of Haiti climactic but it's gonna be so cool make sure all the code works if anyone has any tips for programming and ESP 32 to like talk to an Android phone please leave them in the comments I'm expecting I'm gonna have to make like a custom Android app that will just send notifications to it but if you guys have any tips at all please leave them in the comments I will definitely write guys that's it for this one thank you so much for watching don't forget to Like and subscribe if you have not already check out my Instagram page where I post updates about my projects way before they come out on YouTube and I'll see you next time [Music] keep those big clunky smartwatches that look like you hush
