  • Veho MUVI X-Lapse…

    Posted on by rob

    A few weeks back (well, quite a few if I’m honest), I was sent the MUVI X-Lapse by LOVECASES to review and put through it’s paces.  I was impressed by the size of it, however it’s small size does also have a downside…

  • RPI + RaspiCam = Time Lapse Photos

    Posted on by rob

    While chatting with a friend today about my new Venus Flytrap plant they asked to see it catch a fly .. well that’s kind hard to capture as it’s a lot of chance (unless you shove a fly into one of the traps).  So I got to thinking, I can use my Raspberry Pi and the RaspiCam to take time lapse photos using raspistill then stitch them all together into a video.

  • Samsung Galaxy S4 arriving soon..

    Posted on by rob

    I’ve finally pulled the trigger and ordered my new Samsung Galaxy S IV from Vodafone today.  My S3 has served me very well over the last year and I can’t complain about, it’s been a crack’n bit of kit!   I can’t decide if it’s a good thing or bad thing, but with the new phone will come the need to replace some of the accessories that go with it .. the S4 won’t fit in my current car holder or the current phone case.

    There are so many options available already for the S4, it boggles the mind.. makes picking one so hard haha

    So far my choice of case would have to be the Samsung View Smart cover or

    Or the Samsung Flip case, however I don’t like that the camera can’t operate with the cover flipped all the way over the phone.


    I’ll have to wait until the phone arrives next week to work out which case might be best for me… oooh I can’t wait for it’s arrival.

    Now to look for info about rooting the phone to make the most of it ..

  • Raspberry GPIO…

    Posted on by rob



    I’ve posted before about struggling to find a real use for my Raspberry Pi, I’ve started to move a bit closer to some sort of end goal I think.. while looking through various Raspberry Pi news feeds I came across the mention of something called the BerryClip, a little add-on board for the RPi that was sold by Raspberry Pi Spy in kit form on Ebay.   The purpose of the kit is really to learn about controlling some of the GPIO ports.  The board ships with a web link to the site that has the build notes for the kit as well as a bundle of Python code you can download and play with.  The board, as you can see, comes with 6 LED’s, a micro switch and a buzzer.   The sample code has some basic demo’s of turning the LED’s on and off, with and without the button and buzz with a button push.

    I’m really not a python programmer, mostly out of laziness for learning yet another language haha.   So, I embarked on a quest to use the the board from a bash shell.   Hizaa, I found WiringPi.  This is a command line tool to control the GPIO functions of the Pi.  It took me a while to figure how to map the GPIO ports to the pins as there are different ways to do this.   Having found this I started to build a script to learn how to make the BerryClip do stuff.   So, I wrote Berryclip.sh.  <– You can download the script from that link.  I may update the script from time to time so check it from time to time if you want to get the latest version .. the files are versioned so you’ll see the difference.

    2013-04-16 12.56.352013-04-18 14.57.22

    2013-04-18 14.57.442013-04-18 14.58.20

    So, what does the script do?  Well, a previous unreleased version did this

    Since I made the video I’ve cleaned up the script, reorganized the menu options as well as enhanced the options and added more.

    So the main menu currently looks like this

    Version: 1.4
    Date   : 2013/04/20 19:53:37

    Pick one of the following options

    1 – lightfollow  – The lights will all turn on and off
                       after each other
    2 – cylon        – The lights will follow each other
                       like a Cylon / KITT
    3 – policelights – Alternating Police style lights
    4 – beep         – Beeps the buzzer
    5 – switchtest   – Only tests if you push the button
    6 – switchbeep   – Press the button to beep the buzzer
    7 – switchleds   – Press the button to light LEDs

    D – Set the delay between lights off/on and beeps
    Q – Quit
    What do you want to do?

    I may well add more options to the script, there is still more I need to learn .. ie: how to turn on multiple LEDs at one time rather then sequentially.  I’m not entirely sure it can be done with GPIO alone, it’s possible I may need to use Python, while Python is still turning them on sequentially it’s able to do it so much faster then the gpio script and bash.

    Morse Code

    While learning about GPIO from writing that script I had another idea … button + speaker = Morse Code .. this got me thinking, could I make some sort of a Morse Code trainer sort of thing .. so I wrote another script which you can download and play with, morseclip.sh.   Currently the open options you are:

    1) Set the transmission speed of the Morse code, hard coded speeds (currently) are:  5 WPM, 12 WPM, 20 WPM and 30WPM, however I’m not happy about the sound of the 30 WPM option .. the other speeds are near enough spot on.

    2) Enter the text you want to convert from English to Morse Code.  Currently all English letters A-Z, Numbers 0-9 and a few punctuations are supported, you’ll see those when you enter the menu for sending text.


    As always, the scripts are free for the world to fiddle with,  credit back to me would be very much appreciated.  I’d love to hear feed back on the scripts and even more, I’d love to see links to new updated versions of them if you mod them.

  • Where is my PI?

    Posted on by rob

    raspberry-pi-580-75[1]Hashtag[1]Unless you use static IP’s or a DHCP reserved IP for your PI (or really, any Linux based computer) how do you know where it lives on your network?  This might not be an immediate issue for you on your home network, but what if you take your PI with you to another network for some reason?  It could also be used to simply let you know when a machine has been rebooted and is back on line..

    Read on to find out how I fixed this problem…
