If you are one of my 3,567 “subscribers” who is a real person and not a crawling spam bot and are genuinely interested in getting notifications of my junk.. ha ha.. let me know, and Ill add you manually…

The Window

The first of my VR experiments is almost finished. The Window is a one room claustrophobic experience for Google Cardboard. I like the way that VR has kind of pushed back the idea of “the short game!” Wearing a cardboard device for more than about 5 minutes is painful and impractical so we have to make short interactive “ideas” fit that format. It brings to mind the typical quirkjy YouTube clip, or before that the single floppy “demos” on the Amiga, that I loved so much.. had a big collection… oh wait a minute.. and before that.. THE SINGLE!
What is it with that time slot? 4 or 5 minutes seems to be a nice little slice of time?
Anyway, The window explores the way to move around with no interface or controller, not totally solved, it has a few ways to interact with things, a phone, a door, a button and an electric guitar. Things change, but will you notice? until its too late? A little environmental in message, and quite dark.. in a Stanley Parable kind of way…

Coming soon on Apples App store… not free, but “virtually free” ha ha

NEW Ordo Ab Chao Site

I decided to divide off my computer games and film stuff off onto new site, Ill continue to update om misc things blog style here, but I needed a less messy container for my more serious experiments into computer games and VR. Im hoping sometime to get some funding for this art, and infact to get some of my old films onto digital format for re-showing them, so they are included on the new site as well.
The site is called www.ordoabchao.no

Flicker film

This is the movie I made to show behind me play in Santa Cruz in 2010. For some reason I had not posted it on my site before now.

Its silent, I made it in After Effects, its basically 2 layers of random textures, lots of found footage and scratchy film, that are combined using a mask of a 3rd and rather flickery layer. (For some reason its showing 4:3 here. Its not, its 16:9… but who cares really?

KIPPLE, CARVINGS & CROSSES @ NESODDPARKEN

Kipple, Carvings and Crosses.
Today I had my exhibition at Nesoddparken!
I was very surprised at how many came and that some braved the Norwegian seas and came over from Oslo. I set up a table so children could make their own kipple and that was also very successful!
I got a lot of nice comments and people seemed to like it a lot
Guri Guri Henriksen and team put on a fantastic shadow theatre show in the “project room” that was extremely well received, we had a class from the local school visiting the artists studios, and attending a painting course… Today Nesodparken felt just like Portsmouth Art College circa 1983!!!

Special thanks to Mark Steiner who did all the fiddly Facebook event stuff, and certainly contributed to the attendance, and also Trine Brandeggen who helped me organise and mount the stuff on Friday, and finally my lovely wife Hilde, who puts up with Kipple on a daily basis…

The exhibition is now showing for nearly a month, and a Sunday visit is recommended due to open café, and various events!
Reminder, (nearly) EVERYTHING is for sale, just sms me, on the number on the price-list and stick a little heart shaped sticker on the one you want, thus “bagging” it.

Virtual Box stuff for Mutable Instruments software burning

After successfully burning the software to the ARM chip on the clouds module I thought Id better collect all the instructions down in one place. I still havent gotten Braids to work, but Im not deterred, Id still like to make Frames, Grids, Edges and.. er that new morphing modulator one.. forgotten..

Anyway here it is…

Get Software
Install Virtual Box https://www.virtualbox.org/wiki/Downloads
and the extension pack (same page)
Install vagrant https://www.vagrantup.com/downloads.html

Get Code
Go to the MI git repository at https://github.com/pichenettes/eurorack
and click DOWNLOAD zip (you unless you know what you are doing with github, which I don’t)
Unzip it
This folder is your MASTER directory for MI building. it is called:
mutable-dev-environment-master
In it you will see, loose a file called Vagrantfile.
In order to run vagrant your computer must be able to see that file, that means navigating to this folder via Terminal.

Starting Vagrant (these instructions copied from https://github.com/pichenettes/mutable-dev-environment)
Open Terminal
Hard to describe how to do this without knowing where you have saved your folder. But you need some knowledge of command line navigation. Either:
you know it
You go to https://wwwcodecademy.com/ and take the Learn the Command Line course (recommended)
wing it… heres some hints

Command line 101
Use ls to show a list of files and/or directory that are in the current directory
Use cd to change directory so cd documents will put you in the documents folder, then you can run another ls and see what the contents there are. hopefully, you saved the mutable stuff there, and all you need to do is cd mutable-dev-environment-master and you are in the right place
use cd.. to go up one level, just incase you go in the wrong folder

Type the terminal command to start up Vagrant. That is:

vagrant up

The first time the VM is started, all tools will be downloaded, and the latest version of the code will be grabbed from github. The process takes about 15 minutes, depending on the speed of your internet connection or computer.

Then login to Vagrant (again in the terminal, NEVER in the black terminal lookalike window that Virtual box throws up, was a mistake of mine)Type:
vagrant ssh

THE MAKEFILE
You then need to change a few lines in one file, this is to tell it to upload via StLink (I think)
So look in the main eurorack-modules folder,
open the stmlib folder
Then try to open makefile.inc
You probably need to use a very simple text editor, like Text Edit. But it wont recognise the filetype .inc but will open.

The relevant lines should look like this (ignore those starting with #, they are just comments):
# Supported: arm-usb-ocd, arm-usb-ocd-h, arm-usb-tiny-h, stlink-v2
# PGM_INTERFACE ?= arm-usb-ocd-h
PGM_INTERFACE = stlink-v2
# hla for stlink-v2 ; jtag otherwise
# PGM_INTERFACE_TYPE ?= jtag
PGM_INTERFACE_TYPE = hla

Leave no spaces at the end of lines

Now back in terminal
You can begin to build things
Do these one at a time.

to clean the area reserved for the bootloader
make -f clouds/bootloader/makefile clean

to clean the area reserved for the software
make -f clouds/makefile clean

to build the bootloader
make -f clouds/bootloader/makefile hex

to build the software
make -f clouds/makefile hex

That should be it, but there’s an option to do both at once.. not sure if it worked for me

to upload both in one package to the chip
make -f clouds/makefile upload_combo_jtag

Also found in the make file..
make -f clouds/makefile upload_combo_jtag_erase_first

something gbiz suggested when trying to get Braids to work…

openocd -f interface/stlink-v2.cfg -f target/stm32f1x_stlink.cfg -c init -c halt -c "flash write_bank 0 build/braids/braids_bootloader_combo.bin 0x0"

he said
“It’s most of the command that make runs to flash the binary, less a couple of configure options. I doubt it’ll help, but it’s worth a try.”

and I dont think it did…
