- In this video, I show off my Raspberry 3 Portable build, which can be carried around anywhere! and does not require any external grounding connections, because the only wire that needs to be used is the wire that goes from the Power Bank, to the raspberry Pi 3 to power it, the power bank is used as so one could provide proper voltage and amperage to make the pi function. A 3d printed case is used for the housing to protect the components from outside factors; vents are provided with the 3d printed .stl file(s) in order to vent heat which is generated during any CPU operations and electronic transfers.
COMPONENTS LIST:
1. Raspberry Pi 3 Model B
2. 3D printed (and assembled) Raspberry pi case w/ display

“I dunno why someone would need Ethernet”.......... same reason for a WiFi enabled pc to have Ethernet....... speed and reliability
13:25: It's pcmanfm that takes up the processing power! Not the screen! The file manager, ie. the desktop, most likely (long time since I used a desktop on a rpi).
It's weird though, as he has no icons on the desktop... most likely the Pi is underclocked, so it shows what usually takes 2% or so as 20%, lol.
If i want to connect the screen and than a thermal camera which goes through the gpio pins can i do so? or does the screen take up all usable gpio pins? Please respond
sorry for the long reply, I was away for a while, first of all, it depends on what kind of connection does your thermal cam use and how it connects. It is possible to connect a camera through soldering to the remaining 14 GPIO pins, it would be quite crowded but possible. Keep in mind that different gpio pins perform different tasks, so depending on your camera's requirements, it might or might not work, if you have any questions please write back.
''It's completely wireless except for this wire here..'' lol u made my day. xD HAHAHAAHHAA
Sorry But I think that you didn't understand the purpose of this video, or you just haven't worked with Raspberry Pi's before. As I say several times in the video, this design CAN be made completely wireless by soldering a battery unit to the Pi board itself. However, this is difficult and selecting a proper battery power supply (PU) is not effective (in my opinion) my case doesn't have a place to mount a PU, so I went with a USB power bank for phones. Please note that this design can be made wireless, the wire is just to connect it to the power supply. Technically a laptop is wireless too, but it still requires a cord to charge....
Man I know I was just kidding :)
I'm owning Rasp 3 myself and right now I'm working on a concept with purpose to win a contest :)
I was just kidding so don't take it seriously great job man
JovanPlaysEverything thanks man. Sorry if I was being mean to you LOL. I have just had many trolls and haters on my channel recently. That sounds like a great contest man, I hope you win, or at least get a high position. Me, myself, I don't know much about programming and coding with the pi, to be honest, I actually practically don't know anything
HOW DID YOU GET THE SCREEN TO DISPLAY RETROPI I HAVE 3.2 INCH WAVE SHARE LCD SO WHEN I INSTALL RASPIAN THE LCD WORKS BUT AFTER I INSTALL RETRO PI I CAN ONLY SEE SCREEN IN HDMI TV MODE? HELP PLEASE I BEEN WORKING ON THIS FOR ALMOST A MONTH?????
Unfortunately, I don't currently know of any other way using which you can get Retropie to display on the LCD touchscreen. There are ways but you have to have very good knowledge in assembly and machine language so you can manually configure the Retro pie Operating System to by default run the video output and touch input through the GPIO pins. Im not good at programming and I dont know any languages so I cant make the drivers for it.
3.2 INCH SCREEN INSTRUCTIONS -GOT IT WORKING WOOHOOO ANY BODY ELSE HAVING TROUBLE GETTING RETROPIE TO WORK ON YOUR LCD SCREEN FOLLOW MY EXACT STEPS GUARANTEE IT WILL WORK FOR YOU.
_______________________________________________________________
STEP1 COPY PASTE AND ENTER ALL COMMANDS
git clone github.com/swkim01/waveshare-dtoverlays.git
sudo cp waveshare-dtoverlays/waveshare32b-overlay.dtb /boot/overlays/
STEP2 now edit your config.txt
sudo nano /boot/config.txt
STEP3and add these two lines to the very bottom;
dtparam=spi=on
dtoverlay=waveshare32b
STEP4ctrl+x then y then enter
sudo reboot
STEP5 again quit ES drop to command line, check the existence of your new tft display by typing;
ls /dev/fb*
you should see dev/fb0 /dev/fb1
/dev/fb1 is your tft
if you don't see /dev/fb1 you've messed up and need to start over
if all is good,
STEP6 Now we get retropie output to your tft.
sudo apt-get install cmake
git clone github.com/tasanakorn/rpi-fbcp
cd rpi-fbcp/
mkdir build
cd build/
cmake ..
make
sudo install fbcp /usr/local/bin/fbcp
STEP7 now to launch fbcp automatically we need to add;
sudo nano /etc/rc.local
STEP8 Before, the final “exit 0” line, add the following:
/usr/local/bin/fbcp &
STEP9 ctrl+x then y then enter
sudo reboot
you should now see retropie/ES on your tft screen!
DUDE YOURE A GOD MAN THANKS SO MUCH!!
MineCralex YOUR WELCOME BUDDY GLAD I COULD HELP MAN CHEERS!
BolowArizona thanks soo much... I might be doing this when I get a pi 3, this is so helpful... One thing though, what would happen now if you plugged into HDMI while in use? Will it swap to the HDMI and back when HDMI is disconnected? (like the Nintendo switch does)
I was thinking of getting one of these. But compared to getting a 5 inch HDMI touchscreen, these GPIO based ones mostly requires a custom raspbian (that's if you don't know how to install the drivers) and that the refresh rate of the display is very poor. It would be hard to play games or even watch videos. So I'm planning of simply getting a 5 inch touchscreen that uses a HDMI bridge connector instead which only requires you to edit the config file for it to work.
that is a good idea, however, it would increase the size of the pi significantly, I do completely agree with you on the horrible refresh rate, and difficulty in playing games, and practically doing anything on the pi including browsing the web. Epiphany browser crashed on my pi a few minuets ago, and when I turned off the pi, I wasn't able to turn it back on, because the OS crashed. It is EXTREMELY unstable, and it is very difficult to work with the pi with such a touchscreen. However, with a 5" HDMI touch screen, you would still have to install matchbox keyboard and config the system to make it touchscreen friendly, because the OS wasn't made to be touchscreen compatible. ALSO: if you buy the same touchscreen I bought, you wouldn't have to install the drivers, I have a pre-configed OS already made, download in the description.
MineCralex I already own a mini Rii wireless keyboard for my raspberry pi 3. And I didn't buy the 5 inch touchscreen since you were right about it being too big. I instead bought a Kuman 3.5 touchscreen and manually installed the drivers on my current raspbian rather than downloading the offered OS from them. Touchscreen isn't really an essential for me since I just need something to show what I'm typing.
Jason Lee The Kuman touchscreen that you bought is exactly the same one i bought!, It is a great company with great shipping which is free even though it ships from Guangzhou, China.
MineCralex Yeah I chose it because it had the highest reviews compared to the other brands.
Jason Lee it is also more expensive than most screens/brands, I saw some cheap screens on ebay for less than $10 a pop, but I was concerned with configing the OS and installing drivers to make it work, so I chose the Kuman one because it has free download of OS.
Hey MineCralex, do you know if you can config the screen to put two screens on NDS Emulator? :3
I have a case with fan, but when I use lcd I don't have space in that case for fan cooler. Is it normal? can I use for hours without fan cooler? without problems? thank you
is the power bank 2.5a?
I'm trying to do one with a 5 inch screen but I need to used to cables one for the screen and one for the pi if not it will show me a yellow icon on the screen
The second USB Output on the power bank is 2.4 Amps, the 1st one is only 2.0 amps. If you use the 2.4 amp output, it should actually be enough to run the pi as I have even heard people running Pi's on 2.3 amp power. I don't know how much amps your 5" screen draws, but check it and make sure that it works from an outlet, then check it with powerbank and it should work most likely.
MineCralex thanks for the answer
what would happen if you had the screen attached and suddenly attach a hdmi cable? would it automatically switch to HDMI video output?
No it would not, I do not advise doing so, because the OS is pre-configured by the manufacturer of the screen (download in the description), and has the drivers specifically set to work with that specific touchscreen, what would happen is one of two things, 1. Nothing would happen, HDMI screen would be blank, display would be on touchscreen OR 2. OS crashes due to overload/confusion, and because it is not configured to run with HDMI. I think that to connect it to HDMI, one has to go into terminal and raspi config to change some things for it to work.
can you charge the battery while in use ?
Yes
yes use a 2.1 amp 5v charger , dont use a 1amp it will draw more then charge
I really want this case but I dont have a 3d printer, is there another way to get one ?
Thank you for the question, for one, you can buy a case from EBAY or from amazon or other store, in which case, the case won't be 3d printed. Another way you could do, is you could find a local 3d printing service online to print and ship the components to you. You simply need to download the .zip file (link in the description), unzip the file, and if you are running Windows 10, you can view the .stl files and order a print service from there.
can you give me the link of pre-configured Raspbian OS?
isn't rpi3 overheating without overclocking ?
I'am writing to you on the behalf of MineCralex, I am currently away from my home and don't have access to my MineCralex account, so I was forced to use another account, however, this is MineCralex posting::::: The Rpi3 can overheat without it being overclocked, however, this is rare, and judging by the amount of software availability and runable programs on raspbian, my CPU usage rarely even reaches over 70%, without artificial or forced stress testing, it is very unlikely that any components, especially the CPU, will reach over 80 Celsius, a more troubling problem is that the OS tends to crash every so often if you overload it too much.
isnt 80 c too much
actually, many laptop gamers get their laptops to around 80-90 C with no issues, I would not advise such temperatures for expensive and powerful processors, because there is a small risk associated to heating it up to 90+ C, however, it is unlikely the processor will break, its processes/clock might slow down and it might be slower in the long run if it is subject to such hot temperatures, but most processors can work just fine
It always depends on the hardware. The Pi3 is rated for 85°C safe operation and it will slow down beyond that to keep the hardware safe.
ZLau13 i think 85c still shortens life so better keep it below
how am I SUPPOSED TO PROGRAM???
Hi I'm new to this channel and already linking it, I bought a raspberry pi 3 model B around March this year with the exact same touchscreen you're using. I need help getting the screen to work with Retropie if possible, I've looked everywhere and the tutorials I see have a different kind of screen. I've had my pi collect dust for a while still hoping I can get this portable emulation station to work. If you see this thanks for reading and hope you can help.
Hey, I'm really, really sorry that I got so late to you. I had many things to do and wasn't able to log onto my youtube account in a long time. Exactly what is your problem? can you explain in greater detail and I might be able to help you. The thing is, you need special drivers to work with your selected OS, in this case, RetroPie. I use this operating system on my Pi as well from time to time. I'll try to make the screen work meantime, but can you please reply as soon as possible just so I can communicate with you and see exactly what you want to do with retropie.
when are you coming back to steam?
Wow, someone actually checks my account lol, I got locked out of it, but I have the email, so I will recover it, I was just so lazy so all I did was play minecraft and kinda forgot about steam :)
+MineCralex ye cuz steam is fun also i added you plus i love linux
ReisenFruit hey dude, sorry for not being on steam, I try to be active, but i got f-ed over by the steam trying to confirm my email or change it, so i ignored it, then it locked me out and now I have to reset password.
How did you make it show up like that! It almost seems fake. When ever I turn it on it just goes to a white screen and stays there.
Man it boots really quickly, what is your Sd???
I have a 32 gb san disk platinum I think??? I actually forgot a bit because I haven't used it in such a long time. Regardless, the card is level 10 speed, and U3, which is quite fast. Actually, If you get a good card that is at least 10 speed and U1, which are actually quite cheap, most pi's boot very quickly, the OS isn't that intensive and if you don't have too much files on it its very fast.
Do you think it works with Pi3, and Official 7' display, using ps3 controller (wired or Wireless)?
can you please specify? do you need 2 screens to work at once? so you want both this screen to work together with a 7" screen?
if i put mp4 video's into my sd card..can i play video's on the small screen monitor?
But you need headphones or a speaker
Does the power bar on the pi work?
Ahem, Unfortunately not. I'am quite sure that you might be able to configure it so it does, but not by default. If i need to check the level of the battery pack, I can simply press the power button on my power bank and it displays 4 LEDs, which correspond to the level of power left.
can you make more pi vidieos . that wid be cool .
yeah sure, I'll definitely look into it, thanks for the feedback.
Why not just glue the lcd cover on?
Eactly, he is a total newbie.
ı want to use my powerbank but ı am not sure what should be the values
Barkın Var it should be 2.1A or amps
The Raspberry pi 3 B, the most powerful and energy-consuming raspberry pi, the recommended amperage should be around 2.5 Amps. 2.1 A should work but I recommend 2.4 A, which is more than it'll ever need. Most, if not all powerbanks have specs and Amperage written on the box, the spec sheet, or the powerbank itself.
and the bag . you said you will show wats in it .
There is nothing in it, but I usually keep my stylus, LCD screen, powerbank. the pi itself, etc. in it. Sorry about that. My filming isnt professional, although I'am working hard to make it better. All my videos are fully unscripted and I usually just dive in and film when I have free time.
Needs more rocket boosters.
what Ampe and volt does your powerbank give?
the rating is: 5 V DC / 2.4 A (port 2) - 2.1 A (port 1)
Cool
it can run games?
the answer to that is yes. Raspberry Pi 3 can run Minecraft (pre-insalled), although a special Raspberry pi edition. In addition to that, the Pi is able to run "RetroPieOS" an Operating system that has tens of emulators from which you can play Commodore 64 games, Nintendo games, atari games, ps1 games, etc. The list is almost endless.
thx for the answear :) (sorry Fr)
How long can 9000mah powerbank power suply rpi?
14 hours on mine ,and i got mine of some shady chinese site and probably is weaker and around 7400mah , forgot to mention that mine has no screen because i ssh into it,if you have a screen it probably last half with wifi or bluetooth on ,i got a usb voltage checker and it sucks alot of power with a screen and wifi on
Jessica Westly i gather from your comment that your running a linux or debian os? If so what battery pack are you using and how steady is the power while running intense program's?
yeah im running a Debian kernel ,i got a new belkin 10,000 mah for $25 on sale its a flat cell pack,it works even better its outputs up to 2.1-2.4 last very long , power remains steady and even added a small fan connected thru gpio pins , just make sure what ever battery you use check if it can output 2.1 amps but ive noticed it doesnt even use that much unless you have a screen attached,wifi on ,bluetooth ect
"Well this sucks" 😂😅
13:30 n00b that is fucking nothing lol! What about the OS!!! You forget to subtract that from the numbers!
what is the the price
Well, I don't directly sell any components of this Raspberry pi build. The raspberry pi 3 B costs $35, the battery pack costs around $30-60 depending on which one you buy, the one I bought can be found as cheap as $30, but its a really good battery pack which can be used more than just for running pi's. The screen costs $22 that I used, but it can be found on ebay for as low as $10, but be careful which you buy, because some of the are old and dont even work with the new Raspbian and the drivers I provided. The 3d printed case, I got it for free, but you can order a 3d printing service, idk how much $.
is it cancerous?
10:54. your welcome.
Yeah man, sorry for the crappy filming, I didnt expect my sd cards to fail XD
MineCralex lol. happens to me
hay Alexey how are you
I'm good how are you
u know u just got that for picraft
what do you mean? I use the protable touchscreen raspberry pi for a variety of applications.
badly preppared vdeo
aR Bemo lol like your comment
I guess it could of been better made. I guess the majority of the youtubers recite and possibly write down their speeches before they make the video. I just speak straight from my thoughts. Also, I just dont have a good lit place to film
minecraft
yep
minecraft dude !
It's garbage, a fail
Will the screen work with retropie emulation station?
vermiman yes
