Web, Graphics & Industrial Design

We often meet our destiny on
the road we take to avoid it.

Welcome to ernstrenner.com

my virtual playground where I post information about me, some of the things I have done so far and the exciting projects I am associated with.  These days, I spend a lot of time on developing an online music school for creative children which is challenging but also very rewarding. 

My latest eBook project

An early draft of my next eBook Arco Linux B “Because less is more” are available online and you are welcome to read up on Linux, the XFCE desktop environment, custom theming and more advanced topics such as mounting a remote web server in Thunar and more.

Industrial Designer / Builder

Concept Car Render w 3D Blender

Back in 2013, I’ve completed all required classes at the British Columbia Institute of Technology (Dept. of Engineering) towards an Associate Certificate in Computer Aided Design Technology
Education always pays off and now I am able to make professional 3D-printed custom parts which transport my models from the screen into the real world. FreeCAD and Blender 3D are my main design tools. Ultimaker Cura is my preferred slicer which lets me tweak all the settings needed to print a perfect 3D model on my amazing Artillery SW-X1 3D printer.


Piano players have speedy fingers and yes, over the years, I have worn out several qwerty keyboards. Instead of writing about my “writing“, I’ll let the trademarks and copyrights listed below speak for themselves.

Music Teacher

ernst renner music teacher

My music career began in Austria and continued after my immigration to Canada.  I have worked with two youth orchestras and conducted the Concordia brass band in Saskatoon.  Over the years, I’ve spent countless hours playing, teaching, arranging, conducting and composing music.

In 1999, I took a break from all of that and went to work for IBM which was interesting but once the Y2K rush was over, I returned to teaching piano and brass until I moved to Vancouver. 
British Columbia was love at first sight and once I settled in, I began to develop iPad and iPhone apps which lead the Little Composers School of Music and Composition which is my brain child and last project.


I had the privilege of working on countless music projects and spent a lot of time in the recording studio laying down more tracks then I can remember. I recorded radio commercials, played piano for a hotel promo video and over the years, put together a nice portfolio of original compositions.

One of the CD’s I produced mentions this about me on the inside sleeve:
“Finally, heartfelt gratitude goes to Ernst, whose imagination and dedication turned these songs from mere dreams to reality”. – Ronda L.

My home-recording studio is my favorite place and I love how technology shrunk a big $100000+ recording studio down to a $2000 audio interface and a $3000 computer plus a good microphone and a few cables.

Because of that, I can offer the following audio services:

  • Original sound tracks
    Ideal for presentation videos or CG animations.
  • Arranging and recording
    My arrangements and tweaks can fix or replace the parts you don’t like.
  • Scoring and transcribing
    Got a CD with a tune and need the music score? The only way to get the real thing is to transcribe it as the music was played.
  • YouTube assets
    Can’t find the right background track for your promo video? I might already have it and if not, I can make it happen.

My favorite software

95% of my work is done with opensource software running on the Arch Linux platform.
Here are some of my must-have programs:

  1. 3D Blender
    A fully integrated 3D graphics creation suite
  2. GIMP
    For image creation and photo editing
  3. FreeCAD
    A general purpose 3D CAD modeler
  4. CURA
    Slicing software for 3D printing
  5. Shotcut
    Cross-platform Qt-based video editor
  6. MuseScore
    Create and print sheet music
  7. Reaper
    Audio production DAW
  8. SublimeText
    Sophisticated text editor for coding and HTML scripting.
