AKI: books and work
This afternoon, Andy and I visited the last day
of the AKI Finals 2016 at the AKI. I met
Ilse Löbker and received two of
her books, which she had hand made for me. These are:
- Vertaalconcept: The Old Man and the Sea / De Oude Man en de Zee, a
translation concept that starts with the text De Oude Man en de Zee,
the Dutch translation by Els Veegens-Latorf and A.W.F. Werumeus Buning from
The Old Man and the Sea written by
Ernst
Hemingway and gradualy changes into the original English text.
It costed € 45.00.
- Verbeelding: de wereld van tekst en geheugen, Bachelor thesis,
for € 25.00.
I also met with Annejet Riedijk and told her
that I had decided to buy the work about which we had exchanged emails in the
past week. She told me that the work was intended to be a more strongly lit
location and showed it me in a more brightly led environment.
Stil.l.leven02
This morning, I bought the work Stil.l.leven02 by Annejet Riedijk. I met her at the AKI and brought the work home after
having signed the purchase agreement. I am very happy with having bought the
work.
At 11:32, I bought the book De Nederlandse Identiteit in de Kunst na
1945 edited by Geurt Imanse written in Dutch published by Uitgever Uniepers
Abcoude in 1995,
ISBN:9789068251654, from thrift store Het Goed
for € 2.50.
Gerrit Rietveld Academie
I went to Amsterdam, where I arrived around half past 11. I first went to
bookshop Scheltema. I bought one book as a
present for Meindert. Next I went to Het
Martyrium where at 13:27, I bought the book Alan Turing's Systems of
Logic: The Princeton Thesis edited by Andrew W. Appel written in English
published by Princeton University Press in 2014,
ISBN:9780691164731, for € 7.00. Just before two o'clock, I arrived
at Gerrit
Rietveld Academie, where I met Meindert and some of his family and friends. We met there as part of his
birthday celebration and also see the finals exhibition of the students. I would like to mention the following
students:
Komputerstrukturen 3 and 3a
Just recently, I studied some photograph taken at an exhibition at the tenth floor of the Neudeflat organized by
Utrechtse Kring with works by Peter
Struycken, when I noticed that Komputerstrukturen 3 and 3a were included. This is the only photograph I know of these works
allowing me to resolve some issues with respect to reproductions of these works
in various publications. Some part of Komputerstrukturen 3a is obstructed
by an Structuur sculpture from 1986, which makes it impossible to make a final
verdict.
Compared to the design as given in the item
AB15700, Komputerstrukturen 3 contains one difference: In row 8, column 4
the work has a white square, where the design had a black square. Which means
that it seems that there are three anomalies (under the assumption that each
two by two square should have had two white and two black squares according
to the input given to the program that was
used) in the work:
- Row 8, column 4 should have been black according to the design given in
AB15701.
- Either row 23, column 4 or row 24, column 4 should have been black.
- Either row 28, column 3 or row 28, column 4 should have been black.
The reproduction in Recente schilderijen (1970) of Komputerstrukturen 3 has no differences
compared to the work, and because it has one difference with the design, it
seems that it is based on (a picture of) the work.
Compared to the design as given in the item
AB15701, the visible part of Komputerstrukturen 3a has one difference: In
row 50, column 29 the work has a black square where the design has a white
square. It appears that the reproduction of the work in Recente schilderijen (1970) is equal to the design AB15701 except for the
same differences with the work, suggesting that this reproduction is based on
the work. If this is the case, than it is likely that the obscured part of the
work is probably also equal to the design. Which means that the work seems to
have the following three anomalies:
- Either row 4, column 3 or row 4, column 4 should have been black.
- Quite likely row 50, column 7 should have been white. On the design one
can distinguis the Dutch word "fout" (with means: "error") on the side
with line to the square. It appears this was overlooked when the work was
made based on the drawing.
- Row 50, column 29 should have been white, like in the design AB15701.
The reproduction in
P. Struycken komputerstrukturen seems to be based on the design
AB15701, because it does not have the difference found between the design and
the work. It has a total of eleven differences with the work. These are:
- Row 2, column 45: changed black to white.
- Row 8, column 18: changed white to black.
- Row 10, column 39: changed black to white.
- Row 20, column 31: changed black to white.
- Row 20, column 32: changed white to black.
- Row 23, column 46: changed white to black.
- Row 29, column 43: changed white to black.
- Row 44, column 7: changed white to black.
- Row 48, column 5: changed white to black.
- Row 48, column 7: changed black to white.
- Row 50, column 29: changed black to white.
Dividual Notebook
In the evening, I ran into a man who I know since 1981. This happens about once
every five years. He too has been writing diaries for a long time and
continueing to do so. He was together with Brigit Egging, who graduated from
the AKI in 1984 and now works as an artist in Ireland. This summer she is back
in Enschede and working on a project called Dividual Notebook.
Three book
At 11:42, I bought the following three books from thrift store Het Goed:
- De AKI tekent: tekeningen van docenten edited by Arno Kramer and
Sipke Huismans written in Dutch published by Hardy Uitgeverij in 1998,
ISBN:9789075522105, for € 1.95.
- Verlichting voor luie mensen written by Paul Smit written in Dutch
published by Samsara Uitgeverij b.v. in July 2012,
ISBN:9789077228890, for € 1.50.
- de aki schrijft / gezichtsbedrog edited by Arno Kramer written in
Dutch published by Jan Groen, AKI in 2005 for € 1.95.
thermgraph
In the evening, I finished the thermgraph.ino
program for the IJduino. The
IJduino is an Arduino like
device with an eight by eight led display. It requires a DHT22 temperature and
humidity sensor to be attached. The program will show a graph of the
temperature of about the past half hour. I want to use it to determine when to
close the door and windows when in the morning (during the summer time) I open
them to reduce the temperature inside, because at some point the temperature
outside will get higher again and keeping the door and windows open is of no
use. (Some people open the windows during the hotest time of the day to enjoy
the cooling effect of the blowing wind, but by doing this, they actually might
increase the heat inside for the rest of the day and especially the night when
they want to close the windows to keep mosquitoes outside.)
Last Tuesday, I started developing
this program while at TkkrLab. Someone
suggested to install CuteCom and use an additional USB cable to connect to the
communication ports of the Atmega328 chip, such that I could use Serial for
debug output. Someone suggested I first check if it was working with the
DHT-sensor-library. It did. I studied the library and decided to
implement my own communication with the DHT22 sensor to understand how it
works. After having finished the program, I uploaded it to
FransFaase/ijduino and
send a pull request to IjHack/ijduino after I made repository up-to-date with upstream. The pull request has been merged.
Temperature graph
This morning, I used my IJduino with thermgrap program
to record the temperature changes, after I opened the door and windows. As one
can see, the temperature dropped quickly and remained stable for some time.
When It went up agan (around white line), I closed the door and window. And
the temperature went gradually up again. Around the yellow line, I let the
digital thermometer hang freely in the air, to see if that made some
difference. I switched of my PC for some time and later switched it on again,
after which the temperature started to rise again. Maybe because of warm air
flowing along the thermometer which was hanging over the edge of the table
under which the PC is standing. I think, I will repeat the experiment again
tomorrow with the thermometer in a different location, further away from the
PC. The graph show to the right was drawn by hand and might contain errors.
I am already thinking about a better method for recording the temperature over
a longer periode of time.
A, a novel
This morning, I finished reading a, A Novel by Andy Warhol, which I started reading on April 18, 2014, four days after I
bought it on April 12. The book contains the
transcript of tapes that Andy Warhol recorded of Robert Olivo talking with others. Nevertheless, pages 344-345, contain
some of the most revealing statements ever made by Warhol in public about his
inability to feel happy, while he is being interviewed by Joe Campbell, in the
book refered to as Sugar Plum Fairy, his nickname within
The Factory. One of
the other persons, Billy
Name, in the book, just died yesterday. I still have many sheets of notes
that I have to add process, so in a sense I am not yet finished reading this
book.
At TkkrLab, I connected a HC-06 Bluetooth
module to my IJduino with a
1KΩ and a 1.8KΩ resistor to bring the 5V signal from TXD on
pin 3 of the Atmega328 down to about 3.3V for the RXD pin on the HC-06. For
this I connected the KΩ resistor between pin 3 and a free row on the
breadboard and the 1.8KΩ resistor between pin 7 (VCC) and the same
free row. From this row there goes a wire to the RXD pin of the HC-06.
See picture.
After having this all connected and checked twice (earlier, I checked the
resistors with a digital multimeter), I switched it on. A small led on the
HC-06 started blinking and the IJduino performed as expected displaying a
temperature graph. I first tried to enable Bluetooth on FJF2, my netbook, but that did not work out.
Then I decided to find some Android app bluetooth app for my tablet. After
some tries, I installed Arduino bluetooth from Giumig Apps, paired with the HC-06 and switched
to terminal mode and saw the output from the Serial.print() calls in
thermgraph.ino. Mission completed.
Star Trek: Beyond
This afternoon, I went to see the movie
Star Trek: Beyond.
To be honest, I was a little disappointed. On positive point that I have to
make is that the way in which Zachary Quinto portraits Spock is becoming more like how Leonard Nimoy portraited him. I guess, I
am disappointed because this movie looks too much like all other superhero
action movies that are around today. There are only dialogues that go a little
deeper, such as the moment that Spock becomes philosophical about death.
Tetem
I visited the TETEM art space. I first looked
at the exhibition Gogbot Tribute to Remko Scha. I enjoyed listen to and looking at
The Machines by
Remko Scha. I also liked
"No Noise II" by Jochem van der Spek.
Next, I looked at Multi Solo: The Rhythm Painter. I liked the music of The missile knows where it is by Nils Mühlenbruch. I was not very impressed by the three video and
sound works under the artist name microseq
of Pandelis Diamantides.
Finally, I looked at the exhibition The Rhythm Painter: Shape Your Identity with the Shape your
identity installation, a machine that makes music and images (appearantly
not working when I was there) based on a fingerprint scan. You can also turn
some knobs and push some buttons to change the music. But the effect of this
seems to be minimal. Nevertheless, I enjoyed playing with it. This time all
the exhibition rooms did have something with sound in it.
News ticker
This evening at TkkrLab, I decided to
further experiment with the Bluetooth communication. For this reason, I took
the code of the IJduino cp437 program and first modified it to make it display the
text to move from right to left at a fixed rate. Next I started experimenting
with a method to read a new text from the serial interface, which is connected
to a Bluetooth HC-06 module. The readBytesUntil method on
Serial seemed the way to go, where the first paramter is given the value 10 for
the newline character. The working program: newsticker.ino. Using the
Arduino bluetooth app, I could enter a new text in the IJduino news
ticker program. Next I wanted to also be to send a text from my netbook. Last
week, I already tried to enable Bluetooth on my netbook. Now, I tried to use
a Bluetooth stick that I bought a long time ago. I opened it up (just by
removing a piece of tape holding it together, because it had already fell
apart), and found the number BC04, which seems to indicate it is a Taiyo
Yuden® Bluetooth BC04 External Bluetooth USB device. I inserted it and
experimented with some bluetoothctl commands. I managed to get a /dev/rfcomm0
device and wrote a small C++ program to write the text Hallo Frans to
the given device, which when executed did cause the text to be displayed on
my IJduino. (I could also have used echo 'Hallo Frans'
>/dev/rfcomm0 command, I realized later.) I still would like to find
out how I could connect to the HC-06 module without having to give all the
bleutoothctl commands.
I also tried to build my Acorn Atom emulator,
which I succeeded to do after some modifications to the make file with
respect to include directories and dependencies (make depend did not
work). When I executed it, a window displayed, and a lot of messages about
illegale opcode, because the Acorn Atom Roms were not included in the start-up
directory. I must have them somewhere or see if I can use the
Acorn ROMs.
Book
I received the book On Numbers and Games written by John Horton Conway in English
published by CRC Press in 2000,
ISBN:9781568811277, which I ordered on last Wednesday from BOL.com for
€ 61.02. It is a different book than I had in mind, but nevertheless,
I am quite happy with it. I am going to use it as preparation for a talk with the title: "From Nim to Go to Surreal Numbers" that I plan to
give on ZomerGo.

Bluetooth with HC-06
