How To Take Timelapse Photos with Raspberry Pi


CanSatLogoAs part of our CanSat endeavours, we are going to use a Raspberry Pi to do some time-lapse photography as we descend after launch.  In order to do this we’ll need to configure our Pi to do this automatically.  Read on for a description on how to do this.

Introduction to CanSat


CanSatLogoI’ve been fortunate to become involved with the CanSat competition in Ireland this year.  I’m playing the part of Industry Mentor to a team of students from Gairmscoile Mhuire, Athenry, Co. Galway.  Our team have called themselves Gairmsat.

So in Part One, we took an old external had drive, and added it as storage to a Raspberry Pi.  In Part Two, we took that Raspberry Pi and shared the new folders on the local network.  In this final tutorial, I’ll show what all of this has been for, and show you how to create your own Home Theater Raspberry Pi.

How to Share a Folder on Raspberry Pi

In part one of our tutorial, we discussed how to mount an external hard drive or USB drive on to our Raspberry Pi (or any other Linux based) computer. In this tutorial we will discuss how to share folders from that computer to your local network. I am doing this so I can share the media files I have on my external hard drive, and access them from many places on my network, such as my laptop, my android phone, and my Raspberry Pi running XBMC. You can use this tutorial to share files in a similar way.

I’ve got a Raspberry Pi, and I’ve got an old external hard drive. So what can I do with them? I decided I was going to create a networked shared drive from them, so in this first tutorial, I will show you how to mount the drive on a Linux operating system.  Doing this is easy, but can get a little tricky when you attach and remove drives on the fly.

Going Dark to Fight SOPA.



Copyrights vs. human rights by opensourceway

Copyrights vs. human rights by opensourceway


On January 18, this blog, alongside many other websites, is going dark for a day to protest against the proposed introduction of the Stop Online Piracy Act (SOPA) and its Senate counterpart, the PROTECT IP Act (PIPA) in the USA. SOPA will not just affect those in the USA; its knock-on effects would touch every website in the world. Under the proposed legislation, it would be illegal for us (or you) to link to any website – any website at all, including community-driven behemoths like YouTube, Flickr, Blogspot or WordPress (where we’re hosted) – without checking first that nothing on that site infringes copyright. And we’d have to review those sites continually after a link was made.

Under these Acts, every person making a link to such a site would have to check the millions of other pages on that site to ensure that nobody, anywhere, is breaching copyright. Even search results would be covered under the proposed law. And if a website like ours were to be prosecuted for linking to another site where copyrighted material was hosted, our domain could be confiscated and our IP address added to a USA-wide blacklist, even though we are not US-based.

So far, so ridiculous. It’s censorship and shifting of responsibility on a grand scale. But despite a loud chorus of opposition to the Acts from legal experts, internet experts, journalists, website owners like us, human rights activists (want to publicise the next Arab Spring using Twitter, Facebook, YouTube or another site that potentially infringes? You’ve just provided the powers that be with an instant excuse and mechanism to shut you down) and ordinary people who just surf the web, the Acts stand a genuine chance of being pushed through. Lobbyists like the Motion Picture Association of America (MPAA), the Recording Industry Association of America (RIAA) and the movie and music studios have much louder voices and deeper pockets than we individuals on the internet do; but by joining together on January 18 we hope that we can make enough of an impact to be noticed by those voting on the legislation, and by the news outlets that they read and watch.

So on January 18, this blog intends to join the planned shutdown organised by Reddit. This site will be unavailable from 8am EST to 8pm. We encourage those of you who can to join us – and if you’re a US citizen, please call or email your representative.

Exploring Arduino

A few months ago, my local maker-space (091 labs) presented a few informal tutorials on Arduino.  Having seen it mentioned online, I decided to bite the bullet and drop by to learn more.  Shortly later I purchased the Experimenter’s Guide for Arduino, which was used during the tutorials.  Being further interested in Arduino and it’s capabilities, I subsequently bought the Arduino Cookbook, by Michael Margolis (O’Reilly).
