라즈베리파이 4로 노트북을 만들어보자! Let’s make Laptop with raspberry pi 4

January 21, 2020

This time, let’s make a laptop with Raspberry Pi 4. Anyone without 3D printer or special tools
can make Once you have some ingredients can easily get. I’ll make it With travel plastic laptop case I’ll use it as a case Because the interior space is so large
There seems to be little difficulty in working The top panel for the display uses Formax Well cut to fit Now let’s make room for the display Finally cut There’s a little crooked part and I think I can just touch that part The display will use a 13.3-inch LCD display Next we will attach the keyboard to the bottom plate I bought this keyboard from AliExpress. It can also function as a mouse Most products with keyboards and touchpads are wireless. This can be used by wire using USB As you can see, I bought a size that fits inside So now I have to cut here I think the plastic is a bit thick Let’s challenge with a cutter knife Let’s start Because here is separated I’ll take it out and cut it I think it took about 20 minutes Dig the bottom plate with acrylic knife To keep the upper part of laptop open You can use the torque hinge like this. Now look It won’t fold with this much strength This allows the laptop’s top to stay open and locked. The outside is over and it’s time to work inside. Many parts are waiting So let’s get started Raspberry Pi Pi 4 is known to have significant heat So I prepared a huge full body heat sink case Since I will only use usb 3.0, I will remove usb 2.0 first. removed usb port If you want to cut the usb like me You need to watch out chip resistance or IC chip not to damage. In my case, I put a case on it so I couldn’t see chip resistance and removed this chip I tinkered again Now let’s build a battery pack that requires attention due to the risk of explosion. Battery pack is completed Step down module for voltage reducing to 5V Installed 5V powers with the Raspberry Pi and Power straight out to 12v power on LCD Will supply And because there are several places where interference occurs, I changed the position and cut the necessary parts Now let’s finish Finally the interior is complete Let’s plug in a micro SD card with Raspbian installed beforehand Finally close the lid The body is finally finished If I ever make anything My wife told me to stop making some trash But this time she said that WOW it’s good and pretty Now before we start, there is another thing to do It will be the finish of the laptop with sticker Raspberry Pi shaped stickers attached It looks good Now let’s turn it on Yes, the touch mouse is also good Keyboard is good, too Currently Rasbian is installed. The design seems to be so neat that it can be compared to Windows or Mac. And the programs that are installed by default Office, development tools and Chromium web browser This is the Linux version of Chrome I think it’s good enough for YouTube And KODI can be installed and used like this I installed Netflix In Korea, it is necessary to bypass the video using VPN, but you can watch the video I can’t watch like this You can watch video using KODI like this You can do Netflix The existing Raspberry Pi 3 was quite satisfactory for classic game emulation Running Dreamcast emulation was a bit difficult Then, let’s take a look at the performance of Dreamcast emulation on Raspberry Pi 4 The frame looks pretty good Yes, I looked at emulation games In addition to Dreamcast, the Game Cube is also known to have some performance. As you know, in Raspberry Pi 3 it was difficult to play the Dreamcast game smoothly Raspberry pi 4 do enough now And I should try streaming So far, we have made a laptop with Raspberry Pi 4 Raspberry Pi performance is up a lot compared to 3 Because the design itself and the convenience of the Rasbian itself improved a lot This is enough for simple works Today is here Next time more helpful information And something interesting gadget I’ll make Don’t forget to subscribe and like

Broadcasting Analog TV on an ESP8266!

January 21, 2020

This here is an esp8266. Or rather an ESP-12E
module that houses the ESP8266. A little chip that was designed to do little more than turn
on light bulbs or be in a toaster for the internet of things. There’s one big problem,
though. Espressife gave it way too many peripherals and too much power and made it way too awesome
of a system for it to just be used for internet of things. It’s got peripherals like SPI and
PWM and and ADC. But the most interesting peripheral by far for me has been the I2S
bus that has DMA support, which I’ve used to output to WS2812 LEDs. You can click that
video here. Right now for this video though, I’ve hooked it up to just this wire and here
I have this analog television. So, let’s go plug it on in. Turn it on. And we can see
on the analog television that its outputting. Right now it’s trying to pull an IP address
from my roommate’s router and once it pulls it after negotiating WPA2, it will display
it on the screen. Now, it’s gonna start the demo. Right now I’m showing you it can output
text, broadcasting on channel 3. So, the ESP8266’s got 802.11, it’s got a core it’s got RAM all
these peripherals, I2S with DMA which we can output analog broadcast television on. It’s
got this text mode which is actually running on a framebuffer, which we can use to display
just about anything we want. Why settle for a framebuffer when we can make it double-buffered
and draw all sorts of crazyness? And, we can do a little bit more since we have so much
power left over since we’re overclocking it. We can go display things in 3D. Not just a
few things but a lot of things. And these are static meshes, we can do better. We can
also display dynamic meshes. This is being calculated on the fly on the ESP and displayed
through the framebuffer outputting to the broadcast telvision which is being banged
out the I2S port. While the ESP is updating all this video, it can also serve this webpage
here. Just go refresh it. And uuh, even though it’s outputting all this video and doing all
this complicated stuff it can maintain this websockets connection with this web page.
If you’re curious about more websockets stuff on the ESP, you can click this link right
here. This webpage has the basic stuff like the wifi settings and all of that. But it’s
also got this NTSC tab, which allows us to change the modulation on the ESP in real time.
So we can see how I can click the little button and it changes how the bits being outputted
from the I2S bus are interpreted by the TV there. And, that’s because whenever it’s outputting
these, it’s outputting this down the line. So, this series of ones and zeroes are interepted
by the TV as a black color, a white then a black color, a black then a white, and solid
white and we also need to have a sync because we’re trying to output NTSC. So, if you’re
interested you can check this out on github. Check out these other esp-related videos and
don’t forget to subscribe. Thanks.

Milwaukee Impact Wrench Repair – Replacing the Electronics Assembly (Milwaukee Part # 23-66-2659)

January 20, 2020

“The electronics assembly consists of the
switch, control board, battery terminal, and the LED work light. The assembly fixes problems such as a tool
that won’t turn on, no longer has variable speed, has melted battery terminals, or the
LED light has burned out. Replacing the electronics assembly is a repair
that you can do yourself. I’m going to show you how. Hi, I’m Mark Sodja. Do it yourself repairs like these are easier
than you might think. From lawn machines to cordless drills, kitchen
mixers, outdoor grills, our how-to videos walk you through each repair from start to
finish. Doing it yourself means never having to do
it alone. Let’s get started. I’ll begin by removing the front gear case. I’ll remove the anvil from the gear case. Now remove half of the handle housing. There’s a sticker at the rear of the housing
I’ll cut in half. To remove the brush card, I’ll lift the motor
assembly away from the housing. I’ll pull the armature away from the brush
card. Now, I can remove the electronics assembly
from the housing. As I remove the battery terminal, I want to
be careful to not lose the compression spring behind it. I’ll pull the electronics assembly away from
the housing. Now, I need to remove the brush card wiring
from the switch. I’ll heat the solder connections with my soldering
gun. When the solder softens, I’ll pull the wire
away from the switch. Now, I can install the new switch. I’ll start by re-soldering the wires from
the brush card. The black wire goes to the terminal labeled
M2 and the red wire to M1. I’ll apply some soldering flux to give the
connections and then solder the wires. Now I can install the electronics assembly
back into the housing. I’ll start by placing the LED light at the
front of the housing. I’ll work the wires through the housing around
the shuttle, now reinstall the battery terminal. I’ll place the compression spring in the recess
at the back of the terminal, compress the spring, and slide the terminal back into the
housing. I’ll place the circuit board back into the
housing. As I do this, I’m tucking the wires out of
the way. I’ll line the switch with the housing, and
I’ll make sure that the shuttle is connected to the post on the switch. Now I need to get the brush card ready to
reinstall the motor. I’ll pull the brush out of the holder and
then set it off to the side. There’s some grooves on the sides of the brush
holders to hold the spring. I’ll pull the brushes back into the holders. Now I can slide the commutator into the brush
ring. I’ll place the springs back over the brushes. Now, place the motor and gearbox assembly
back into the housing. I’ll line the notch on the field with the
tab on the gearbox. The notch and tab align with the housing and
lock into place. I’ll make sure the switch, the circuit board,
terminal, and all the wires are tucked down into the housing. Now I can reinstall the other half of the
housing. Now, install the anvil onto the gearbox. I’ll make sure I offset the ears on the anvil
with the hammers on the gearbox. I’ll reinstall the gear case, sliding it over
the handle and aligning it with the housing. I’ll secure it with the screws. That’s all it takes to install a new electronics
assembly in your power tool. Be sure to check back often for new videos
and expert advice. If you found this video helpful, give us a
thumbs up and leave a comment.”

Upcycle: Laptop Bags

January 18, 2020

It’s the year 2020! and let’s challenge ourselves to create something new and something different from the past decade Let’s make something out of Laptop bags! These are from a Thrift Store and it costs 11$ for three I got extra just incase if I screw up I bought different types of bags so that I will have different details I will be making a punk/goth kind of skirt ?? This is actually a fine looking bag and I feel bad cutting it But nobody wants it Let me give him a new purpose in life I’m Yen Shing! And she’s Quinn Today, she will be teaching us how to keep our body in shape and also model too Let’s open up all the pieces and see what we can do with this I do have sketches Never done this before There’s a lot of uncertainties So this video will be mostly exploration Here are my weapons First we remove the strap and start cutting! This is easier than I thought Cut out the handles Open up all the front pieces It just slides by And here are the innards And I’m done~ This is an Asus bag Let’s open it up to see what’s inside Here’s a foam protective layer As you can see, I’m such a pro at deboning laptop bags At this rate, I would be a really good thief Cut out the leftover inner lining And now I am left with the main wire structure Here are some of the items that I manage to cut out and obtain Some zipper pieces, a few of these rings, handles, straps, and a zipper rest of the materials and there’s velcro I’ll keep these two for another project I’m going to figure out the design I’m going to try to achieve a punk looking skirt I have my sketch, pins and clips I’m thinking of some pleats I want to try to use the thicker piece but it’s not blending in Let me just cut out the excess and the undies I wanted to make a jacket out of it but that will require many more laptop bags And end up being more expensive How about hanging belt? Make sure there’s enough to cover her Going to use the strap as a belt Okay, so it will be something like this Sew all the sides together to make one big piece Sew in the pleats or folds Cut a small part of the strap and loop it into the ring and then attach it on the skirt I clip the belt and sew across the skirt I place two adjustable rings so that it will work as a locking system I place two more velcro strap on the skirt so that you can walk or dance around without exposing There’s excess material and I’m thinking to add a top too I start trying out designs on Quinn and and she prefers the sleeved version When I’m happy with how it looks I took out the pattern and trace for the other side And then, I sew all the pieces together I don’t have enough to hem but i think it looks sleeker just the way it is Hey get back to your seat And here’s the final look! The feeling of unknown and unpredictable can be really scary But, if you never try, you will never know Look at her, she’s fabulous! I would like to officially introduce you to Quinn and answer some of the popular questions that we both curated Who’s your favourite designer? Oh not me? And you’re just doing your job as a mannequin What do you eat to stay so healthy? Ah spaghetti straps and button mushrooms like the white ones? I see So she likes spaghetti straps with white button mushrooms So how do you stop yourself from overeating? You pin yourself?! Don’t do that kids Do I have any issues talking to the mannequin? Nah, everyone talks to their mannequin So here you have it Quinn and me doing interview So, See you guys Nice meeting you guys Bye! She’s my companion

January 18, 2020

maker and developer Rory Johnson has
created a new Raspberry Pi laptop using plywood to create a unique portable
system that is now available under the Creative Commons license allowing those
interested to create their own laser curtain wooden laptop the plywood laptop
has been in development since 2016 two years hundreds of hours thousands of
dollars and one partners frayed patience later I finalized the designs for Rev
1.0 of the Pluto the Platonic Amma date the Raspberry Pi
or other similar sized single board computers the laptop has been designed
to enable owners to customize the internal layout adding extra development
boards batteries and other required electronics in any way they desire in
keeping with the idea of complete flexibility there’s no defined layout
for the internals of the ply top rather there’s an array of star-shaped openings
on the bottom plate that allow the builder to connect hardware components
up in whatever way works for them actually suggests just holding
everything down with zip ties to allow for ease of tinkering everything you
need to be Apple II to build your very own clip
