Need to add GPS to your Raspberry Pi? How do i attach a GPS to a Raspberry answers your question!
Earlier on today, the Raspberry Pi Foundation announced that the Model B will now be shipping with 512Mb RAM as standard, with no price change. I posted the link up on Hacker News and its caused quite a lot of happy people!
So, with the news of extra RAM, its started making me think of more things the Pi could be used for…
just a note on the idea of using 3G and Squid for the Pi… This is something i am interested in, so its something i want to start playing with. The idea would be as follows:
Also, using something like WANProxy on both ends should make things faster also… Having the Pi, a 3G modem, USB key (optional) and a battery pack, all in a small box, with a Wifi Adapter, should give you a faster mobile internet connection… And if you could get 2 or more 3G modems (using a Powered USB Hub of some sort), you could do load balancing…
A while back I posted about the Raspberry Pi, and in the post was a link to a Photographer who was embeding a Raspberry Pi into a Canon 5D MKII battery grip. Well, its been a while, and i have been thinking about the Pi and Cameras, so I went looking around… Here is what i found.
The one thing i have not been able to figure out is how to tell the Pi to take the photos out of the camera wihtout having a monitor plugged in. I was thinking either tell it, on boot, to start monitoring the camera and download everything. This way, if you have it plugged into a external power source, it will be monitoring and downloading to somewhere… USB HDD, USB Key, etc. If there is a Wifi spot around, try uploading them to a location, posibily manageable via web interface of some sort… Lots of interesting ideas can be done… its just a matter of doing them… 🙂
As a follow-up to yesterday’s post on RouterOS Blocking Machine access to all but one IP, I thought I would show how to add extra IPs to that list, without having a shedload of firewall filters.
to do this at the command prompt:
this will block any traffic, other than the IPs in the expressVPN address list, for the machine 192.168.0.123.
So, I have a machine on my network, which should be only connecting to the internet through a VPN. I needed to tell my RouterOS box to block all access, except to this said IP address… The following should do the trick… YMMV
this will drop any packets from the srcaddress (IP address) that are not for the destination dstaddress (IP address). in my case, dstaddress is the VPN server I want to connect to. So, in theory, all packets should just go through the VPN and not leak out into the rest of the network… again, still testing this so be careful!
As part of my new task to make my files safer and backups faster, and, well, cheap, I am looking into ZFS for my storage needs. My needs are as follows:
So, ZFS offers all these features. I can export a file share as iSCSI, NFS, SMB, etc. All works well. But the replication stuff is the interesting part…
The plan, which i am working on, is as follows:
Thats the “plan”… Lets see how it actually works out…
Anyway, parts of the process i need to tweak:

Couple of bits and pieces on Jekyll stuff today… I am tweaking the outline of the site, so i am surfing around finding stuff… here is what i have found
If you have any tips or tricks, why not leave a comment and i can add them to the post.
[UPDATED] someone asked in the comments if there was an binary build for this file. there is now! http://handbrakecluster.codeplex.com now hosts the code and binaries, and will soon have help files and documentation.
A few days back, i wrote a post titled Powershell + Handbrake + AppleTV + iTunes = Automatic TV… ish. In it i included a block of Powershell code to bulk convert TV shows from whatever format you had them in to a M4V format for the AppleTV. Well, as they say “If necessity is the mother of all invension, lazyness must be the father”. I have a lot of shows i wanted converted to the AppleTV, so i built something… Its called HandBrake Cluster and is written in .NET 4.5, uses MSMQ and Handbrake to do the processing… The workflow is as follows:
I have run this at home on a couple of different machines, and so far so good… my room gets a bit warmer when i kick this off, and between the 3 machines i ran it on, my FPS count went from just 80-120 on the Godbox, to a total of about 160 – 240 FPS (Godbox = 80-120, Server 1 and 2 are about 40-60FPS).
The next thing i managed to do was tweak my import process for iTunes. I am using a program called iHomeServer for iTunes which is running on the GodBox. It monitors a folder, which is where HandBrake Cluster is writing to, and adds them to iTunes. I can then tweak the metadata using the tool, so i can add art work, tell it which shows are related, and it sets up Art work, title info, etc. It is very handy, and something i am very happy with.
I am a UPC Ireland customer, and have 2 cable modems into the house, both Cisco EPC3925s. These are not exactly great modems for power users, but are grand for normal use… Me, however, being a poweruser wanted something a little more, how should I put it, powerful.
A couple of months back, a tutorial was posted on Boards.ie which showed you How to enable “bridging” on your UPC modem. When i say “Bridging”, they used DMZ, turned off firewalls, static IPs internally, turned off WiFi and DHCP, etc. It worked, quite well actually, but was “odd”… Today, however, there is a new tutorial Enabling REAL bridging on a Cisco EPC3925. I have tried this, and so far, it works! now just to set my router to work correctly, and update my IPs if they change…
I have an AppleTV in the house (3, actually) and I am very happy with its ease of use, size and cost… You can’t argue with the small price!
I also have a lot of content that works great with the AppleTV in iTunes, but I have content which does not work so great with the AppleTV… So, I needed to find a way to convert files quickly and easily… that’s where PowerShell and Handbrake come in…
This may take a few min, depending on a few factors:
I have set files to convert on 3 different machines (the GodBox and 2 other servers) and I am getting speeds of anywhere between 250FPS (on the GodBox running 2 instances of HandBrake CLI) and 40 – 60 FPS on the older servers… on the remote machines, they are sending files to the GodBox folder also, so once everything completes, it’s just a matter of opening iTunes and we are good to go… Now to figure out how to automate the Metadata import…
