Pixel Tips and Tweaks - how to Tweak Aspects of the new Raspbian Skin

Last week. Simon Long from Raspberry Pi released a new version of Raspbian with several new features. The most visible of these is the new-look desktop skin, named PIXEL (Pi Improved Xwindows Environment, Lightweight). There’s a lot of user interface (UI) tweaks both functional and visual… new splash screen on boot stunning background images added a whole new set of icons larger ‘drag handles’ for resizing windows (that’s bugged me for years) windows now have rounded corners new font rendering package for better typography I think the new look is a big improvement and I […more…]

How to Flash an SD Card with Larger than 4GB Image - Raspbian September 2016 update

Yesterday (28 Sep 2016) a new version of Raspbian was released with a brand new skin called PIXEL. I downloaded it on my Mac and tried to unzip it in the usual way. It threw an error, so I assumed the download was faulty and downloaded again. But the error persisted. GAH!!! My friend Albert Hickey (who runs the Egham Jam) had a similar issue on Windows… Les Pounder said it worked fine in Ubuntu though. Didn’t Unzip on Pi I tried unzipping it on a Pi, but that failed too. BOO! However, it was […more…]

Documentation and Commenting Your Code

From observation of the computer industry going back to 1987, when I did a pre-university year at IBM Scientific Centre in Winchester, it seems that the very brightest and best programmers (software creatives) are often not very good at or not very keen on documenting their work. I think the reason for this is often misunderstood. Poor documentation is a source of great consternation in the world of Linux. In fact it’s a large part of the raison d’être for RasPi.TV. We, the users, often feel that the geniuses who write awesome software can’t be […more…]

Linux Voice - Issue 1 - Review

On Saturday I received an email from Linux Voice with download instructions for Issue 1. I don’t know if you’ve heard of Linux Voice, but it’s a brand new crowd-funded Linux magazine (they ran an IndieGoGo campaign in November/December 2013). It’s in print and digital formats. They needed £90,000 to get it up and running. In the end they raised £127,603. But I Don’t Buy Magazines Any More? I haven’t bought a magazine for several years. There’s so much information on the web these days that I don’t really bother with them any more. But, […more…]

Just a short post today to let you know that RasPi.TV has just completed server migration to a new server at Mythic Beasts. Why move? I found out on New Year’s Day that my existing server hosting company was moving from London to Reading. So at the end of January they were going to physically move the rack, containing my server, to Reading. This meant that, while it was in transit, all five web sites I have on this machine, and all my email, would be offline. This was estimated to be ~8 hours. But […more…]

 How to stream vlc from a Raspberry Pi with GPIO control but without being root

Having managed to get VLC streaming from Pi Camera to Nexus 7 Android tablet working, it was only a matter of time before I wanted to stream from the RasPiCamcorder. But when I tried it, I came across an annoying problem. RPi.GPIO needs to run as root (that’s why we always use sudo for our GPIO stuff) But VLC refuses to run as root. This means you can’t run them both from the same program. There’s all sorts of clever solutions people proposed (and I wasted a lot of time unsuccessfully trying them all out) […more…]

How to use DropBox with Raspberry Pi

I wanted to be able to upload photos from my RasPiCamcorder straight to DropBox. So I did a little research and came across an absolute gem of a program called Dropbox-Uploader, by Andrea Fabrizi. A truly brilliant piece of work that gives you access to your DropBox account right from the command line. You do have to jump through a couple of hoops to get it set up (security mostly), but once you’ve done that, it’s a breeze. 1. DropBox account First of all you need a DropBox account. Hop on over to DropBox and […more…]

NOOBS New Out Of Box System for Raspberry Pi owners

Gordon Hollingworth announces a New Out Of Box System for Raspberry Pi owners at the Cambridge Jam. It’s a setup/recovery system to make it easy to set up your SD card from the outset and also recover it if something corrupts. It boots in seconds. To activate it, you hold down the shift key while powering up the Pi. Very impressive and should make a big difference to those for whom flashing an SD card image is the stuff of nightmares. It should be out in a week or so.

How to shoot video and convert it to something you can edit in Pinnacle and other programs

Yesterday I got my shiny new “RasPiCam” Raspberry Pi camera module about half an hour before I had to go out and teach. Being a good boy scout (although I never was one) I was ready for it and had it up and running within five minutes of it coming through the letterbox. But when I got back from school, I shot some test videos that I wanted to edit and publish. You know how it is. You have to publish something on day 1 or it didn’t happen, right? :) I knew there must […more…]

The Self-resetting Raspberry Pi

Recipe for auto-reset Pi. Take one Rev 2 Raspberry Pi, a few carefully selected slices of fresh Python, one GPIO port (’25 vintage, preferably), one relay (a twin pack is OK, but not AA), one Darlington array (leave the spikes on), a sprinkling of mixed wires and arrange it all carefully with a breadboard. It should end up looking something like this… I decided to take the P6 reset header one step sillier further. Just for fun. ;) The idea here is to use one of the Pi’s own GPIO ports to switch a relay […more…]
