Default Raspberry Pi

I got one of these a few months ago...

Primarily so I could have a small computer with a full "Desktop" OS to take with me when I take a trip.

So I picked up a "kit".

It included:
Raspberry Pi 3 B+ (1.4ghz quad-core ARMv8 CPU, 1 GB RAM)
Micro SD Card
USB Micro-SD Card Reader
AC power supply
Rasperry Pi case (black, plasic)
Heat sinks
HDMI cable


The Micro-SD card is pre-loaded with "NOOBS" which can install Raspbian (default).
I chose to install Raspbian since it has most/all of the software goodies for the Pi included.

I used the TV/monitor, keyboard and mouse that I use on my (old) Dual-core PC to setup the Pi.

It's not bad for simple things.
Open too many browser tabs thought, and it to starts to lag.

The Pi 3 B+ has:
4 USB 2 ports
1 Network port (RJ-45 I think? same as on a desktop PC)
1 HDMI
1 3.5 mm port (you will have to read about this one yourself, does video too)
1 micro-usb power port
WIFI
Blu-tooth

I went back and picked up the following goodies:
7" touch screen (the Pi 3 mounts to the back of the screen)
Touch screen case (covers the Pi and allows acces to all the ports on the Pi)
Wire-less keyboard w/touch-pad mouse (not blu-tooth. I wanted a small wired)
20,100mah "power bank" to power it when I'm not somewhere with A/C power...


I also installed the touch-screen keyboard program on Raspbian.

Based on various post on forums all over the place, I'm estimating ~8 hours run time.
I still haven't tested that, yet. (which is why it is an "estimate"!)


EDIT:
Ran for 9 hours and dropped the pack to ~51%.
(The Power Bank I purchased has a digital display to show the % of charge remaining.)

END EDIT



While I have seen an article or 2 on getting WINE working, it's not an x86 CPU...
So that means (most likely, still need to check) no SH3/4 or similar...
It does work with DOSBOX which means I could take all my old dos games with me. I'm trying to get all of my games together (and find my floppy drive cable for my dual-core, wherever it is) and get my dos games transfered over to the Pi.
Need to get a better portable keyboard and mouse while I'm at it!

I would like to get this a bit more "wear-able" than it is now, currently it's like a small tablet attached to a battery-pack...

P.S. I'll try to update this with pictures later... Can I put them in my "album" here on subsim?

These are being used to make working versions of old Star Trek desktop displays when interfaced to a video driver board and screen. I plan to do it myself when time permits but I've purchased most of the bits already.

This is the spec list from the build I'll be duplicating.

10.1" TFT LCD Display Module 1080P HDMI+VGA+2AV

Display size 10.1 inches
Dimensions 228.6 × 149.2 × 2.39typ
Viewing area 216.96 (H) × 135.60 (V) mm
Resolution : 1280 × 800
Panel Type TFT
Display Color 16.7M (6bits + Hi-FRC)
Contrast Ratio 600:1
Brightness 350cd/m2
Interface Type Digital
The number of wiring 40 PIN LVDS
LED back light
Operating temperature -20 ℃ ~ 80 ℃


HDMI+VGA+2AV Driver Board:

Dimension: 90.57 X 65.60 X 12mm
Work Voltage: DC 12V
Up to Resolution: 7~22inch up to 1920*1080
Input: Dual/Single LVDS interface
Work Current: 200~250mA
Input Signal: HDMI VGA AV
Audio: Support
Remote: Optional
OSD: Support



Package Includes:

1 x 10.1" TFT Hig-Resolution Display Module
1 x HDMI+VGA+2AV Driver Board
1 x Keyboard with IR receiver
1 x 10 Pins Cable

And the build looks like this but is a functional computer. I'd show an image of that but I don't have permission to use it.

Cool.

My plan ultimately was:
1: A small portable "desktop" to game on while traveling.
2: "Wear-able"
3: Build a small "Beowulf" from several.

I was writing the OP, and had something come up, so I had to rush to finish it.
I really needed to be a bit more clear.

I considered gettig a laptop, but all of the laptops are low power versions of the hardware.
If you want to "de-clock" it to save battery power, that's fine.
But give me the choice to crank it up to full power.

At least with the Pi, it's the size of a credit card, so the limitations make sense.
Plus, it's REALLY cheap!

P.S. Can you link to the page/pic?

I can, but it has just moved into a membership realm.

It starts here but I believe you're likely to get directed to the front door.

Yep, "pre-existing members only"...


Ohh well...

I just stay focused on my wearable plans...


Thanks anyway!
