Raspberry Pi

My first Raspberry Pi hardware set up #raspberrypi @raspberry_pi

The keyboard and mouse use a wireless USB dongle. These are not the ones I will use for my vacation, I will purchase a smaller combined one.
The Rasphub is the main “hub” where everything gets plugged into: the pi by USB, USB Portable hard drive, USB keyboard dongle, and USB microSD card reader and adapter. The Raspberry Pi gets it’s power from the RaspHub through USB power. Why I choose the RaspHub was it’s powerful power supply that can power everything up, and it is a cute little raspberry.
What I learned is there is no BIOS. New user struggles. If you power the Raspberry Pi up with no microSD card inserted with a valid OS. Nothing will display on the screen. Once you fulfill that necessary requirement a color palette will display and the OS will boot.
Getting used to Linux is nothing new as I have used Unix in the past (25 years ago) and Mac OS X Unix very sparsely. I am not an expert but I can get by. I thought I will use Raspbian’s File Manger to copy files from the microSD card to the hard drive but the only drive it shows is the boot microSD card. I have to mount the drives first. There is no GUI bard way to acomplish this. Terminal time!
Going through this exercise is a reason why many people won’t flock to Linux, it rely too much on the command line to do simple tasks. Now that I said that I also looked at Puppy Linux and that version does have a mount/unmount utility. So the distro of Linux you choose may not be feature rich through the GUI. That is too bad.
Next I will get the 2.8″ TFT LCD screen plugged in and working. The manufacturers Adafruit are not finished with their Raspberry Pi 2 compatibility code changes. From what I read that LCD only supports Raspbian distro (it comes with the kernel changes prebuilt) so I will use that once it is available.
Onward to learning more about this $45/$35 little computer.

Building a portable photo copier with Raspberry Pi

I need a device that will be an intermediary between a MicroSD card and a hard drive to save off pictures while on vacation.

During Bing searches (yes, I dumped Google as a search engine) I found many older devices that did this kind of thing. They never took off and were very expensive, plus were limited to just doing that.

Enter Raspberry Pi v2! Quad Core CPU with 1GB of memory.

My project will be pretty simple, but I can get creative and advance it further.

 

Apple’ approach with the iPhone and iPad is they can transfer with a dongle any SD card to their internal storage. I use this for many years with our older camera. The new Sony camera we have uses 64GB memory cards and we can fill four on a week long trip easily.

I could do with Apple technology:

  • Buy both a wifi hard drive and an new iPad Mini 3 with 128GB of flash storage and copy the card to the iPad, then from the iPad Mini 3to an WiFi hard drive. This will be very time consuming.  Cost is about $800 for the iPad Mini 3 and the 2TB WiFi external hard drive.
  • I could also use a MacBook Air 11″ and transfer the files directly from the MicroSD card to a 2TB external hard drive. Cost is about $989 for the MacBook Air and a portable external hard drive.

An alternative solution is to use a credit card sized computer with a small screen with the MicroSD card and hard drive both attached and a small wireless keyboard/mouse. I am exploring this simple solution. Cost should be around:

  • Raspberry Pi Quad Core 1GB model ($45) – From Adafruit
  • Adafruit 2.8″ screen ($35)
  • Case from Adafruit  ($5)
  • PiHub with power adapter ($25)
  • MicroSD card reader ($10) – I already have these bought for my camera.
  • MicroSD Card ($15) for OS
  • External portable hard drive 2TB ($90)
  • Wireless Keyboard/Mouse ($20)
  • Total $245

 

I will keep you posted on my progress.
