So I got myself one of these from Ebay.
Its a 320x480 screen that fits to a Raspberry Pi.
After a bit of digging (and fortunately) a backup of the Pi, pre and post installation, I got it working.
The screen came from China, in just a bit of bubble wrap.
I’m interested in using the screen to display caller-ID and album-art for what’s play. So a top word of advice. When you get a screen like this, take a photo of the back...
The back showed, that my screen was a version 3, of a Kedei 3.5 480 x 320 display.
This was the key. I found that these screens are version dependant.
Someone kindly uploaded it and all the information can be found here.
This is what I followed to get my display working -
I got one the other day and it was a v3. I installed Jessie and used the drivers the seller kindly gave me. I uploaded it here for future use: https://mega.nz/#!hhdCTCDZ!UXyyh17uZo3p0O95mNmkGrWjmCv7NUEaofx9-zqoGj0
Instructions from the seller (not in Engrish) were:
copy over the drivers to your pi (preferably to /home/pi)
What this does is copy over a new kernel and the drivers then reboots.
When you update the system:
sudo apt-mark hold raspberrypi-bootloader
sudo apt-get update
sudo apt-get upgrade
Works a charm.
Adam Christianson, picked up on my experimentation with HomeBridge last week. Much thanks
In big news, I now have Apple HomeKit working at home.
Last night I was able to stand outside my house (outside of our WIFI range) and speak into Apple watch, and say Hey Siri, Switch Living Room Lights on. & the correct lights all came on.
This little achievement was due to the fact I had some Phillips Hue Bulbs and the older non HomeKit hub. However, I came across this really neat bit of software that works on the Raspberry Pi. Called HomeBridge.
HomeBridge lets you turn HomeKit devices into ones that are compatible with the HomeKit system. It acts as a bridge, so HomeKit commands are understood by these devices. Their is a fair amount of support for things like WeMo switches etc.
A guide to setup, can be found here -
Essentially, because of the base work to get Apple File Sharing going on my Pi, I had the ground-work in place. Homebrige relies on Avahi, which provides the Bonjour services for the Pi.
To get HomeKit configured and working on your phone. You need to find yourself a HomeKit compatible app. with access to the room/house accessory screens.
This is what I used (Evo App) -
The only tricky part of the process was to make HomeBridge start when the Pi, starts-up. This was more down to my incompetence than hard to follow instructions.
So in summary. I now have a £25 always on Raspberry Pi B. (i.e the old one), running -
** AirPlay Music Streaming, using ShairPort Sync
So, that means I can send any audio from phone’s, iPad’s, Mac etc. to an amp and connected speakers.
*** I have file sharing for both Windows & Mac working. I can use the Pi, as a TimeMachine, copy files in and out. etc. Its slow, but it kind of works.
*** AirPrint, printing driving a label printer and PDF to Dropbox. I can print from iPads, iPhones with ease.
So I’ve just upgraded my raspberry Pi, from Shairport to Shairport-Sync.
So read back a bit, if you don’t know (and I’m sure you do), Shairport turns Pi, into an Airplay receiver.
I’ve got to say, Shairport-Sync is such a big improvement. Its stable, audio actually sounds better. It doesn’t crash…. I’m just investigating using the meta-data so I can get a LCD screen displaying album art and a description of whats playing...
R-PI, just playing nice with Mac this evening….
So, I’ve been playing around with various Raspberry Pi projects for a couple of years.
I’ve had a few hits (caller ID, home automation, audio airplay) and I think only one miss (Time Capsule).
Whats been great, is that its been easy to have Linux machine that doesn’t matter too much if I get things wrong and it breaks, its not mission critical or anything, and unrelated to what I have todo with work.
So I want to try and build a better Mac and PC backup solution, have a proper continuous integration server for mobile projects and GIT server. Working for a Microsoft partner, its also great to get a fresh perspective on what else is out there.
So we’ve had an HP Proliant server (something like a http://news.driversdown.com/Server/200811/27-1061.html ) in our office just doing nothing for a while and I took it upon myself to see what could be done with this box.
First step, as I’m familiar with Debian Linux ( http://debian.org ) was to install that latest Jessie build. This required me to burn a complete install DVD. I needed todo this as the HP server has SCSI DVD and hard-disks, so to get the necessary driver support thats what was required.
Install took about 15 minutes and I had a machine I could use. Next step was to lock the machine away out of sight. I have too many monitors on my desk already so, I needed this machine to just run unobtrusively. I made sure I could SSH to the machine (which I should admit I called Beasty) away from my desk.
Beasty was just connected to the network and powered. I needed todo the majority of work out of hours, so I made sure I could SSH connect to the machine from home over our VPN connection to our office. All good. So back to the same sort of Raspberry PI experience; I now have a fast Linux machine that I can connect to out of sight; we were ready.
I crave as easier life as I can muster (as I’m sure we all do). The next step was to ensure it was easy to copy files back and forth from Beasty. I’m using Macs and PCs all the time so I installed Netatalk for Mac file share support and Samba for Windows file sharing. Netatalk 3 was a little bit of a trauma to get up and running but once done, I could access my home directory and also using an external hard disk on the server use Beasty as a Time Machine for Mac backup.
I then installed CUPS which let me share to Macs and PC’s a couple of Zebra label printers. This has the added bonus is that from iPhone, iPad I can now AirPrint Labels. Lets face it, who doesn’t need that in their life….
So moving on from here. I installed GIT. This was a breeze. GIT means I now have source control in Xcode on my Mac with a secured remote repository on Beasty. I can work locally and then push changes up-to this team server. I’m not sure if this is the way to go as our company is focused around Microsoft Team Foundation server, so I am going to try and get GIT integration going with this and compare with the open source alternative.
So to recap for free ,I have a Mac/PC/iOS File and print server with cross platform source control solution built in about an hour.
Right now I’m installing Gnome Window Manager to take me from command line management to something a little bit more 2015. I’m blogging about all of this while I wait for the install to finish.
I’ll keep you posted...
Please to announce that Bin Collections is ready to run on iOS9 and Watch OS 2.
Many thanks to Scott for sending me a pic of it running on a real watch...
So a little update.
I’ve managed to install CUPS (Unix Printing at its best) this evening; which has been around forever and lets you print from a Raspberry Pi. Interestingly CUPS was developed by Apple. What’s cool after Google-ing a fair bit, I now have a virtual PDF printer that I can print to via AirPrint, Mac, or Windows. After printing something to this printer, I find a properly rendered brilliant looking PDF in my home folder (and shared) on the Pi. I haven’t quite found the time to extend this to copy the PDF’s to Dropbox (Google that; plenty of examples), but that will follow.
Guided by -
A Raspberry Pi Apple Time Machine, doesn’t really work. Yep, this is crushing… Its just too slow, with backups taking days to complete. It kind of works, just not performant.
I’ve realised that (along with lots of others) that the Pi just hasn’t got the umpgh to transfer data quickly enough to connected USB hard-drives. This coupled with an IO channel that is also shared by the Ethernet interface.
So thinking on about this; my current thoughts are to use a NAS enclosure that I can re-purpose to install an uncluttered Linux distort on (I'm favouring Debian). This would would give me the benefits of SATA + Gigabit Ethernet connection. Currently scouring Ebay for suitable 2 bay drive NASs We will see… (recommendations please)
