From: Scientific American: Taking the Earth's Magnetic Pulse [January 1999]
+*** HOWTO for torsion balance cassette box magnetometer:
+
+file:../images/mag1.jpg
+
+following MAKE magazine: http://www.make-digital.com/make/vol08/?pg=47#pg47
+
+and Shawn Carlson in Amateur Scientist January 1999.
+
+with a few changes (cassette case, some tech changes):
+
+1] Separate out tiny polypropylene strands from a thicker cord (bought at OBI)
+
+2] Drill holes (0.8mm) in exact centre top and bottom of clear cassette
+case. Thread tiny strand into tiny needle and thread this through
+bottom hole and then top. Gaffer tape top thread and place cassette
+box so that lower part of thread hangs in free space. Make the thread
+taut by taping several coins to this lower part, and glue both ends of
+the strand with epoxy.
+
+file:../images/mag22.jpg
+
+3] Glue a small mirror to one tiny magnet (4x1mm neodym). With
+tweezers sandwich the thread between mirrored magnet with another
+small magnet.
+
+4] Hotglue a small piece of copper behind the magnet to damp
+oscillations (inducing eddy currents in the copper when the magnet
+moves and thus an opposing magnetic field).
+
+5] Construct a set of nulling magnets by hotgluing four ferrite
+ring magnets (23x13x5) to another cassette box. Polarity should be
+observed so the magnets shoyuld repel each other and will need to be
+held in place while the hotglue dries! These should be centred to
+align with the magnetometer mirror.
+
+file:../images/mag3.jpg
+
+6] See nulling location notes below (question: how critical is
+alignment of nulling magnets vertically with centre of mirror?)
+
+**** location of components/nulling magnets
+
+file:../images/mag4.jpg
+
+from: http://xtrsystems.com/magnetometer/layout.html
+
+Actually, I find that the balance, laser, and detector can be oriented
+in just about any direction but the nulling magnet assembly is often
+best located on the North-South line relative to the balance. The
+nulling magnet assembly can be translated along this line and can be
+rotated to provide suitable alignment. Alignment is achieved when the
+bright red spot of the laser diode falls upon the center of the
+detector and the lengthening of the period of oscillation occurs as
+described in the article. However, the nulling magnet assembly does
+not have to be located to the North of the balance; it can be located
+to the South but it will have to be rotated by 180° for proper
+operation.
+
+It is worth repeating that the nulling magnet assembly must be located
+on the North-South line relative to the balance. If you find that the
+assembly's optimum position lies elsewhere then it is likely that
+there is a significant perturbation in the earth's magnetic field due
+to some local ferrous material. Moving the system to another location
+is advisable under these circumstances as there is likely to be
+considerable interference with the real terrestrial signal.

+
+file:../images/inscdiag.jpg
+
+The device allows for placing of one (magnetic field) surface as an
+inscription or diagram on another (physical) surface. The intensity of
+the local magnetic field changes the frequency of the needle/wires
+back and forth movement. A simple prototype can be constructed using
+an Arduino sampling a coil amplified with an op07 operational
+amplifier and driving a IRF640 MOSFET and the motor of a primitive
+tattooing device. The tattoo device is constructed from a CDROM drive
+motor after: http://www.rentyman.com/neatstuff/tattoo.html
+
+Inscription can be made using carbon paper or directly onto stone,
+plaster or skin.
+
+*Parts:* 2x 10K resistor, 100K resistor, 100mH inductor coil, op07
+opamp, IRF640 FET, battery holder and battery, salvaged CDROM motor,
+biro pen tube, wire, metal brace (from network card), Arduino, gaffer
+tape.

+* [2010-05-15 Sat 12:26] report on mass storage/atmega32u4 <<52>>
+
+Working with atmega32u4, LUFA mass storage code and Riegel FAT/SD library:
+
+http://www.roland-riegel.de/sd-reader/index.html
+
+following:
+
+http://elasticsheep.com/2010/04/teensy2-usb-mass-storage-with-an-sd-card/
+
+For detektors (http://detektors.org). Trying to sample 8000 bytes per
+second and write (later as WAV file, now as unsigned) to SD card with
+FAT16 filesystem which can then be accessed when USB is connected as a
+mass storage device.
+
+USB mass storage is working but under various optimisations and
+configurations we experienced random crashes especially when we used
+one counter interrupt for ADC/double buffer and another (with
+ISR_NOBLOCK) for writing buffers to FAT/SD. Now we have buffer write
+in main (perhaps do double buffer switch here too or change to OpenLog
+code) and settings:
+
+: -Os // for optimisation
+
+: #define USE_DYNAMIC_MEMORY 0 // in SD-reader_config.h
+
+which does not crash but at some points drops samples/does not write
+(we see ADC LED which flashes on buffer fill go dim/flash v fast or
+slow down depending on minor changes in the code.
+
+** causes/questions
+
+*** Is it a hardware problem ... with timing?
+
+Can only test with other hardware eg. teensy, AVR USB key or atmega328.
+
+timing - some kind of overflow? but CTC resets on match.
+
+*** what is with cli repeated in .lss for our code?
+
+For example:
+
+#+BEGIN_EXAMPLE
+ 908: 0f b6 in r0, 0x3f ; 63
+ 90a: f8 94 cli
+ 90c: 9e bf out 0x3e, r25 ; 62
+ 90e: 0f be out 0x3f, r0 ; 63
+ 910: 8d bf out 0x3d, r24 ; 61
+#+END_EXAMPLE
+
+And note that: 0x3d is SPL, 0x3e is SPH, 0x3f is SREG
+
+So in principle is not cli for very long.
+
+See: http://www.nongnu.org/avr-libc/user-manual/FAQ.html
+
+When setting up space for local variables on the stack, the compiler
+generates code like this:
+
+#+BEGIN_EXAMPLE
+/* prologue: frame size=20 */
+ push r28
+ push r29
+ in r28,__SP_L__
+ in r29,__SP_H__
+ sbiw r28,20
+ in __tmp_reg__,__SREG__
+ cli
+ out __SP_H__,r29
+ out __SREG__,__tmp_reg__
+ out __SP_L__,r28
+/* prologue end (size=10) */
+#+END_EXAMPLE
+
+It reads the current stack pointer value, decrements it by the
+required amount of bytes, then disables interrupts, writes back the
+high part of the stack pointer, writes back the saved SREG (which will
+eventually re-enable interrupts if they have been enabled before), and
+finally writes the low part of the stack pointer.
+
+At the first glance, there's a race between restoring SREG, and
+writing SPL. However, after enabling interrupts (either explicitly by
+setting the I flag, or by restoring it as part of the entire SREG),
+the AVR hardware executes (at least) the next instruction still with
+interrupts disabled, so the write to SPL is guaranteed to be executed
+with interrupts disabled still. Thus, the emitted sequence ensures
+interrupts will be disabled only for the minimum time required to
+guarantee the integrity of this operation.
+
+See also: http://www.avrfreaks.net/index.php?name=PNphpBB2&file=printview&t=28683&start=0
+
+*** about ISR_BLOCK and ISR_NOBLOCK
+
+: #define ISR_NOBLOCK
+
+ISR runs with global interrupts initially enabled. The interrupt
+enable flag is activated by the compiler as early as possible within
+the ISR to ensure minimal processing delay for nested interrupts.
+
+This may be used to create nested ISRs, however care should be taken
+to avoid stack overflows, or to avoid infinitely entering the ISR for
+those cases where the AVR hardware does not clear the respective
+interrupt flag before entering the ISR.
+
+from: http://www.nongnu.org/avr-libc/user-manual/group__avr__interrupts.html
+
+BLOCK is standard with global interrupts disabled in the ISR
+
+*** how fast is SD/FAT storage?
+
+For block of 512 bytes? Riegel reports 29 kB/s = 58 x 512 per second =
+58 Hz. We need to write approx 16 blocks of 512 bytes per second at
+8000 samples per second.
+
+also note that FAT32 is reported as faster at 73 kB/s.
+
+*** how fast is ADC?
+
+#+BEGIN_SRC c
+ /* ADC speed - clock / pre-scale and each ADC takes 13 cycles
+ so if we pre-scale of 4 = 8Mhz/4 = 2 Mhz = 153 Khz approx
+ */
+
+ // set a2d prescale factor to 8 (with both set)
+ sbi(ADCSRA, ADPS1); // pre-scale of 4
+ // sbi(ADCSRA, ADPS0);
+ sbi(ADCSRA, ADEN);
+ sbi(ADCSRB, ADHSM); // high speed
+#+END_SRC
+
+*** is interrupt set correctly?
+
+#+BEGIN_SRC c
+ cli();
+ // apparently "Have to set OCR1A *after*, otherwise it gets reset to 0!"
+ TCCR1A = 0;
+ TCCR1B = (1 << WGM12) | (1 << CS10); // check OK. CTC . no prescalar
+ OCR1A = (F_CPU / samplerate);
+ TIMSK1 = (1 << OCIE1A); // check OK
+ TIMSK0 = 0; // do we need this
+ sei();
+#+END_SRC
+
+*** FAT notes
+
+: cluster size = bytes per sector (512) * sectors per cluster (32) = 16K
+
+Slow down is happening in fat_write_file in fat.c (Riegel) as each
+time we want to go to the next cluster get_next_cluster is called one
+more time each round. So as position increases/file grows we call
+this over and over. Why?
+
+Seems like we look at first cluster pointer in directory entry and
+then read ref to next cluster in the FAT and then next ref...
+
+But if file is contiguous?
+
+*** solutions
+
+change double buffer
+
+open directory and create file first
+
+append file only in 512 byte chunks:
+
+0) do we need a new cluster (16k)? if so append
+
+1) Write the 512byte sector.
+
+2) Change the size in the directory table entry.
+
+(but what about FAT table for clusters? in append?)
+
+*** test other FAT libraries:

+
+*** other issues
+
+- centre of the ADC signal (is now from 0-255). this needs to be
+ checked/tested with op-amps and biasing. DONE
+
+- we can perhaps save time using left adjust and just read ADCH (but
+ will need to switch bits round)
+
+*** rough notes
+
+Other variables could be manipulated off of a stack frame by declaring
+them in the ISR (not static).
+
+try the naked attribute, that will kill all the pushing and popping,
+apart form the stack pointer.

+#+END_SRC
+
+** the stack
+
+How to detect RAM memory and variable overlap problems? You can
+simply run avr-nm on your output (ELF) file. Run it with the -n
+option, and it will sort the symbols numerically (by default, they are
+sorted alphabetically).
+
+Look for the symbol _end, that's the first address in RAM that is not
+allocated by a variable. (avr-gcc internally adds 0x800000 to all
+data/bss variable addresses, so please ignore this offset.) Then, the
+run-time initialization code initializes the stack pointer (by
+default) to point to the last available address in (internal)
+SRAM. Thus, the region between _end and the end of SRAM is what is
+available for stack. (If your application uses malloc(), which
+e. g. also can happen inside printf(), the heap for dynamic memory is
+also located there. See Memory Areas and Using malloc().)
+
+The amount of stack required for your application cannot be determined
+that easily. For example, if you recursively call a function and
+forget to break that recursion, the amount of stack required is
+infinite. :-) You can look at the generated assembler code (avr-gcc
+... -S), there's a comment in each generated assembler file that tells
+you the frame size for each generated function. That's the amount of
+stack required for this function, you have to add up that for all
+functions where you know that the calls could be nested.

+*** 17/03/2010:
+
+**** TSL257 photodetector
+
+file:../images/pd.jpg
+
+- straight into Arduino with supply (middle pin) as 3.3v gives best results.
+
+- fixed for mini-skry platform using main.c.photoamp with TSL257 on
+ ADC3 - pin 6 of mini-skry
+
+**** FGM-3 fluxgate magnetometer
+
+- on mini-skry using main.c.fgm3x on pin 6 (note also FGM needs 4.5v
+ and rest of circuit 3.3v)
+
+- we just print counter which is related to frequency as calculation
+ uses too much program space
+
+*** 18/03/2010:
+
+**** Hard Drive

+- see looper for gnuplot script to reread live data (a=0, load looper)
+
+- also using octave to convert to audio semi-succesfully
+
+: xx=load("hdvoice");

+The two coils are wound in opposite directions with respect to each

+so that external magnetic field noise common to both coils is
+cancelled out. The signal from the sample in one of the coils can then
+be detected with minimal interference. Both coils are large enough to
+accomodate a 2.0 ounce (59 ml) bottle containing the sample.

+(ping) packets and pass these into [[file:island2.org][island]] memory buffer.
+
+** TODO send ping packets (to who?) from the island
+
+Using:
+
+: extern void icmp_send(struct sk_buff *skb_in, int type, int code, __be32 info);
+
+How to construct the socket buffer (sk_buff)?
+
+Some hints:

+
+At first the module was crashing due to null pointer ref.
+
+http://www.paulkiddie.com/2009/11/creating-a-netfilter-kernel-module-which-filters-udp-packets/
+
+provides a good starting point but apparently since 2.6.20 the sk_buff
+is not double dereferenced so we have struct sk_buff **skb rather than
+a single asterisk:

+option for all MCU types where the SRAM doesn't start at
+0x800060. Thus, the linker is being faced with two -Tdata
+options. Starting with binutils 2.16, the linker changed the
+preference, and picks the "wrong" option in this situation.
+
+From: http://www.nongnu.org/avr-libc/user-manual/malloc.html
+
+So, where does sram start on the atmega128?
+
+At 0x0100 -> 0x10FF so we start at 0x1100
+
+and we shouldn't relocate anything there! (heap is only for malloc)...

+The .data segment (where initialized static variables are stored)
+starts at location 0x60, which is the first address after the register
+bank on a 2313 processor.
+
+Also:
+
+Direct Addressing Mode : For example the 128 bytes of SRAM in the
+atmel at90s2313 is all directly accessible for reading and writing you
+can simply specify the address you wish to store data at and read data
+from in the instruction . The ram starts at 0x60 ( look up previous
+tutorials to see why ) so after the 0x60 you can simply read and write
+using the LDS and STS instructions by simply sepcifying the address
+which goes something like this ..
+
+LDS R16,0x60 ;move the value at 0x60 to R16
+STS 0x60,R16 ;move the value of R16 to 0x60

+Note data->.bss is 0x0400 = 1024 in decimal = size of array we initialised:
+
+: unsigned char x[1024]="1234";
+
+Note also: Because of the Harvard architecture of the AVR devices, you
+must manually add 0x800000 to the address you pass to the linker as
+the start of the section. Otherwise, the linker thinks you want to put
+the .noinit section into the .text section instead of .data/.bss and
+will complain.
+
+How this map translates into hex format?

+Avalanche transistor white noise from reverse biased 2n3904

+over the serial interface) is used now as PWM [pulse width modulation]
+for the higher voltage (using 1N4001/4004 diodes and a 10uF

+
+*** memory management: flash/rom and SRAM sections
+
+http://www.nongnu.org/avr-libc/user-manual/malloc-std.png
+
+[for the 128]
+
+**** The .text Section
+
+The .text section contains the actual machine instructions which make
+up your program. Includes:
+
+**** The .initN Sections
+
+init code
+
+***** The .finiN Sections
+
+exit code
+
+**** The .data Section
+
+This section contains static data which was defined in your code.
+
+**** The .bss Section
+
+Uninitialized global or static variables end up in the .bss section. Includes:
+
+***** The .noinit Section
+
+**** The .eeprom Section
+
+**** avr-size
+
+The avr-size program (part of binutils), coming from a Unix
+background, doesn't account for the .data initialization space added
+to the .text section, so in order to know how much flash the final
+program will consume, one needs to add the values for both, .text and
+.data (but not .bss), while the amount of pre-allocated SRAM is the
+sum of .data and .bss.
+
+**** malloc?
+
+The variables __malloc_heap_start and __malloc_heap_end can be used to
+restrict the malloc() function to a certain memory region. These
+variables are statically initialized to point to __heap_start and
+__heap_end, respectively, where __heap_start is filled in by the
+linker to point just beyond .bss, and __heap_end is set to 0 which
+makes malloc() assume the heap is below the stack.
+
+**** what is the heap?
+
+The standard RAM layout is to place .data variables first, from the
+beginning of the internal RAM, followed by .bss. The stack is started
+from the top of internal RAM, growing downwards. The so-called "heap"
+available for the dynamic memory allocator will be placed beyond the
+end of .bss.
+
+**** note from scrying makefile:
+
+EXTERNAL_RAM = -Wl,-Tdata=0x801100,--defsym=__heap_end=0x80ffff
+
+and we use memory pointer directly from 1100 - how do we avoid writing
+over variables (in serialtest.c case).
+
+**** TODO test serialtest code in scrying
+
+in new code - also PORTE is set strangely (for gplog to 0x00 , for
+main log to 0xff)
+
+same in noise2.c where we write to 1100+ and don't set PORTE
+
+possible answer as using:
+
+: avr-size noise2.o
+
+we see:
+
+: text data bss dec hex filename
+: 8336 4 10 8350 209e noise2.o
+
+how can we see what is in data and bss (-s switch)?
+
+: avr-objdump -sh -S noise2.o
+
+gives:
+
+: 0000 0ad7233c
+
+but in the case of serialtest.o we have 621 bytes of data which is all
+text messages (for help and so on) which we know doesn't get
+overwritten???
+
+only conclusion is that data segment is not moved by Makefile (or
+possibility that as it is stored in ROM/FLASH????)

+#+OPTIONS: toc:nil num:nil
+
+http://1010.co.uk/images/openeegryan.jpg
+
+** Background
+
+Sensory Response Systems is an exploration into audio-visual
+performance using an array of sensors responsive to physical movements
+in order to control the audio-visual output in programmes such as pd
+and Max/MSP. It also looks at reshaping and replicating the body
+through the use of fabric, textiles and technology. We draw from
+inspiration and definition through reference to embodiment,
+phenomenology, post-modernism, post-humanism, performance, physical
+computing and computer sound.
+
+Ryan Jordan is currently studying MFA Computational Studio Arts at
+Goldsmiths College, London and developing a large scale dance
+performance integrating the human body and technology. He is also
+setting up a research network based around this area and working
+part-time with a community music project.

-*** January 10th 2009 2PM+: Tonewheels--drawn sound and light music with Derek Holzer
-
-TONEWHEELS is an experiment in converting graphical imagery to sound,
-inspired by some of the pioneering 20th Century electronic music
-inventions. Transparent tonewheels with repeating patterns are spun over
-light-sensitive electronic circuitry to produce sound and light
-pulsations and textures. This all-analog set is performed entirely live
-without the use of computers, using only overhead projectors as light
-source, performance interface and audience display. In this way,
-TONEWHEELS aims to open up the "black box" of electronic music and video
-by exposing the working processes of the performance for the audience to
-see.
-
-In this workshop, participants will learn about different optoelectronic
-components (photodiodes, photoresistors, phototransistors and
-photoelectric cells) and how they can be used to create sound from
-natural or electronic light sources in our everyday world, as well as
-from lasers and other modulated light sources. Circuits to drive motors
-in order to create hand-drawn spinning "tonewheels" will also be shown.
-
-For more information, see: http://www.umatic.nl/tonewheels.html
-
-All places are now taken!
-
-About the instructor:
-
-Derek Holzer [USA 1972] is a sound artist who has performed live
-audiovisual sets using laptops and the Pure Data programming language
-since 2001. Becoming frustrated with the performance limitations of the
-computer, he began new experiments with all-analog, light-driven systems
-in the summer of 2007 which led to the TONEWHEELS live performance.
-Since then, TONEWHEELS has been performed in Germany, the Netherlands,
-Sweden, Italy, Estonia, Poland and Belgium.
-
-Workshop fee: 12 euros.

-*** January 17th 2009 2PM: Wave-length with Martin Howse
-
-The development of human eyes for the reception of radio waves ... is
-quite inconceivable... the real difficulty lies in the much longer
-wavelengths of the radio spectrum, which make the accommodation of a
-directive aerial array, or antenna, a difficult problem. In fact, in
-any reasonable sized animal the aerial system would probably determine
-the appearance of the animal to the exclusion of all other features.
-
-[Radio Astronomy. F. Graham Smith. 1960]
-
-
-Wave-length proposes an open exploration of the physical
-characteristics of various wave phenomena: sound, light and radio,
-with the latter two encompassed under the heading of electromagnetism
-[EM]. Wavelength in all instances has a direct relationship to
-oscillation and thus frequency, to resonance and to any form of change
-in time and in space. In the case of radio waves, wavelength is
-translated into a highly physical architecture of antennas, dishes and
-arrays approximating patterns of reflection and refraction. Whispering
-galleries and sound mirrors provide inspiration in the audio
-realm. These domains can also be mapped to the microscopic, with
-diminishing wavelengths, microwaves, leading into a light which
-literally colours perception. Wave-length acts as a guiding principle
-of scale and measure with detection or exploration determined by the
-quasi-scientific expansion of sensory apparatus.
-
-The wave-length workshop will explore both sound and EM phenomena from
-a spatial perspective: the construction of a landscape of antennas,
-oscillators and detection or measurement devices using simple
-materials. Participants are welcome to bring any materials or objects
-for wavelength exploration.

-Workshop fee: 10 euros.

-
-A new horizon has been opened, outdating the separation of
-transmission and reception that had been forced upon electronic media.
-
-[Tetsuo Kogawa]
-
-The Ghost and the Leech actively explores alternative radio
-constructions, ranging from powerful transmission devices (1W+ FM),
-which can well extend the range of personal broadcast, through the
-psychophone [Franz Seidl] for time/space dislocation, to simple
-parasitic gadgets, harvesting power from radio waves
-[fernsehturm]. Participants will construct a selected device, gaining
-knowledge of simple principles and methodologies.
-
-The workshop proposes an imagination which extends beyond "free
-radio", "natural radio"; an inserted ghost question for polymorphous
-radio prosumers, Berlin's new Raketenmensch ["live forever, in a
-clean, honest, purified Electroworld"].

-*** February 28th 2009 2PM: Amplitude modulation with Antony Hall[UK]
-
-This project is based on an early experiment in sound recording, where
-a water jet was used to amplify and record sound onto a wax
-cylinder. A laser (rather than a water jet) can be used to amplify and
-transmit minute inaudible sounds. With this technique it is possible
-to hear the sound of light through modulation and reflection. For
-example it can be used as an instrument able to detect the high
-frequency modulations from electronic light, or to create techno beats
-from a bicycle light. By using a modified laser projected through a
-droplet of fluid - or 'Fluid lens' - it is possible to create a
-sensitive microphone. If this lens also contains microscopic
-creatures, their movements will generate sound by creating distortions
-with the movement of their body and antennas. The lens also responds
-to subsonic architectural 'sound’.
-
-During the workshop participants will investigate the use of solar
-cells and other light sensitive components to generate sound from
-light, use lasers and LEDs to transmit sounds, use liquid
-droplets to create sensitive microphones and use liquids dynamic
-physical oscillators [chemical oscillation and cymatics]. Antony will
-also demonstrate the muio interface, biofeedback experiments and both
-mlog and ilogs from the owl project.
-
-Please bring laptops or sound recording equipment if you
-can. It will be useful to bring sonic material or patches that
-could be used for generating sound for transmission. Sound cards,
-mixers, mic-preamps will be useful for experiments but not
-essential.
-
-**** About Antony Hall:
-
-Antony Hall is a multimedia artist with an interest in freshwater
-biology, biophysics, electronics, and the physicality of
-sound. Working within contexts such as universities and museums, often
-in collaboration with scientists. He is interested in how we interface
-with science & technology; visually, physically and ideologically; and
-how these interactions effect us creatively and socially. Exemplified
-by an ongoing collaborative work with the owl project producing a hand
-crafted wooden laptop computer (the Log1K & iLog) among other
-instruments.
-
-He has also worked with electrogenic fish, harnessing their ability to
-communicate and navigate with electric fields, creating an artwork
-controlled by the live fish (ENKI).

-*** March 7th 2PM 2009: Audiovisuals with SuperCollider [with Fredrik Olofsson]
-
-syn-er-gy | noun | the interaction or cooperation of two or more
-organizations, substances, or other agents to produce a combined
-effect greater than the sum of their separate effects.
-
-[OED]
-
-A one-day workshop in which we explore synergies in the form of very
-direct and one-to-one relationships or mappings between sound and image.
-The claim is that your music will turn out completely different as you
-cross map with visual elements. And vice versa: your graphics will
-look different as you code them to sound better. Audiovisual mapping
-is a treasure chest of inspiration for control, generation,
-organisation and systemisation of sounds. We will be using the free
-software SuperCollider and, as a springboard, the article 'Audiovisuals
-with SC' (http://www.fredrikolofsson.com/f0blog/?q=node/316). You will
-learn how to make up your own synergies.
-
-Intermediate level - some familiarity with SuperCollider required. You
-should at the least know how to run and modify code examples.
-
-**** What to bring:
-
-1) Laptop running Linux, OS X or Windows
-
-2) SuperCollider 3 installed (version 3.2 or later): http://supercollider.sourceforge.net/

-*** March 21st 2009 2PM: [Out of] Control with Gijs Gieskes[NL] [+concert]
-
-In the future all information might be lost on what a Gameboy is.. so
-then people can still see the Gameboy and wonder what it was used
-for... That's why I buried the Gameboys as a symbol of what
-archeologists might find in the future.
-
-[Gijs Gieskes interview]
-
-Hardware and software imply control. Wide ranging process is
-transformed into logic to be embedded within complex (control) systems
-of economy and being. Control is a promise for the future which is
-already betrayed by cheap, consumer electronics and desktop-bound
-software. Data and circuit bending, crash and glitch, celebrate the
-loss of control.
-
-Industrial designer Gijs Gieskes bends and constructs a vast panoply
-of convertors, translators, sequencers, and controllers morphing
-signals, web data, music, video, software icons, game levels for
-performance and play in the no man's land of contemporary control. The
-one day construction workshop will involve basic electronics and
-simple scripting for the control of consumer electronic devices using
-microcontrollers, Arduino, and throwaway logic chips. Participants
-will also be able to build the hard-soft synth with a kit from Gijs.
-
-The workshop will close with Gijs and participants in performance
-either at micro_research or a venue TBC.
-
-Please bring devices for [Out of] controlling such as:
-
-- walkmans//any portable cassette or dead media player
-- small motors
-- small keyboards
-- any electronic devices... if it runs on batteries we can give it a try.
-
-An Arduino board is also recommended (available from http://segor.de
-in Berlin) but we will also have all parts available to build a
-simpler (free) equivalent.
-
-About the teacher: Gijs Gieskes is a industrial designer, mostly busy
-making devices that do things... Often these devices make music.

-*** March 28th 2PM: Nacht und Nebel with Martin Kuentz.u.a. [with performance 9PM]
-
-Ultrasound, ultrasonics or hypersonics specifies a domain beyond
-hearing, beyond or breaking a necessarily arbitrary limit of the
-audible (around 20 KHz), with a relation to the
-visible. Ultrasound implies a revealing of space (the
-rangefinder, echolocation techniques employed by bats, whales and
-fish), exploration and penetration of opaque media (diagnostic
-sonography), as well as a rendering opaque through the creation
-of fogs from the interaction of higher frequency pressure and
-various liquids. Hypersonic phenomena produce psychological reactions
-and are implicated as transmission means within the conspiratorial
-world of mind control and the other breakthrough of EVP/ITC.
-
-Crossing this audible boundary, ultrasound inspires a domain
-transformation, a potential for transmission and reception, and
-an interference which can be explored within sound making and
-audiovisual cross border investigation. Experimenters within this
-workshop will build and play with ultrasound transducers,
-amplifiers and frequency converters. The workshop will close with
-all participants in open Nacht performance at micro_research

-*** May 2nd 2PM: Frequency Dependence: wave imaging open working group
-
-... Polaroid film can be employed to map the fields directly in less
-than five minutes. The method is both convenient and inexpensive. The
-intensity of a field can be measured by simply holding the film in the
-path of the waves.
-
-[Keigo Iizuka]
-
-Inspired by the work of professor Keigo Iizuka in the late 1960s,
-Saturday's open working group will explore photographic imaging of the
-fields of both ultrasonic waves and microwaves. A variety of wave
-generating setups will be used with super-cooled, pre-exposed film in
-an experimental attempt to record wave patterns of frequency dependent
-phenomena. Participants are welcome to bring sources of both
-microwaves (eg. wireless card with antenna) and ultrasonics.

-*** May 23rd 2PM: Jamming through Runtime workshop and performance with Valentina Vuksic
-
-Jamming Through Runtime, a day-long workshop at _____-micro_research,
-expands and extends Valentina Vuksic's Trip(ping) Through Runtime,
-inviting participants to join with both intrusive and non-intrusive
-interventions into otherwise hidden, interior processes of laptops and
-computer motherboards; a theatre or symphony of hard and soft audio
-interactions.
-
-A collection of elderly laptops is being examined via magnetic pickup
-microphones. The microphones transform the magnetic waves around the
-various electronic parts of the computers. Each action upon the
-laptops can be sensually experienced through a broad range of layered
-sounds. Already plugging the power and booting up an operating system
-reveals an own small-scale universe of sounds and provides insight
-into the complex spare room emerging between hard- and software. This
-space is being explored and further modelled by triggering actions on
-purpose. System analysis tools, stress tests and custom c-programs
-shall bring the characteristics of each machine into the
-limelight. "Tripping Through Runtime“ is part of a longer-term study,
-diving into the invisible interrelationships of hard and soft computer
-matters by sensual means. The project aims at provoking and detecting
-specific behaviour of individual computer components in match with
-adequate software pieces. The microphone demonstrations are part of
-the first experiments to become acquainted with the hardware
-components.
-
-About Valentina Vuksic:
-
-Valentina Vuksic [CH] studied New Media Art at the Zurich University
-of the Arts and Information Systems in Germany. Important works have
-included Harddisko, a noise and disturbance amplifier system for
-harddisks, and Sei Personaggi Part 2, a play in computers.
-
-Please feel free to bring:
-
-- coils, microphones, pickups, other intervention technologies
-- laptops of any age and make, motherboards, microcomputers
-
-Fee: 10 euros (all materials and food!)

-
-micro_research hosts two parallel RFID-inspired workshops with Marc Boon.
-
-RFID sniffer workshop:
-
-The RFID sniffer is a simple analog electronic circuit which can
-detect the presence of 13.56 MHz RFID tags. These tags are commonly
-used in all kinds of plastic cards like access badges, bank cards,
-library cards, public transport passes and so on. The RFID sniffer is
-a fully self-contained circuit on a credit card sized circuit board,
-including battery. During the workshop you will build your own RFID
-sniffer, under my guidance.
-
-Details: http://shop.marcboon.com/snifferkit.pdf
-
-Cost: €20 per participant (this includes all parts)
-
-RFIDuino workshop:
-
-RFIDuino is an Arduino shield for reading and writing 13.56 MHz RFID
-tags. These tags are commonly used in all kinds of plastic cards like
-access badges, bank cards, library cards, loyalty cards and so on.
-RFIDuino consists of a 65x65mm circuit board, which plugs onto a
-standard Arduino (NG, Diecimila, or Duemilanove). The board contains the
-antenna and all circuitry to read and write to RFID tags. It is
-connected to the Arduino using I2C, using the Wire library.
-
-Details: http://marcboon.com/rfiduino/docs/rfiduinokit.pdf
-
-Cost: €50 per participant (this includes all parts)
-
-For the RFIDuino workshop please bring Arduino (or equivalent), and
-laptop.
-
-Please email m@1010.co.uk to reserve a place (strictly limited)
-
-Spiced food will be freely available. Please note this will be the last
-workshop before [[http://1010.co.uk/org/breakthrough.html][Breakthrough]] workshop/event 24/25/26/27 June,
-restarting in July!
-
-*** July 4th 2PM: workshop: Fluxus - Scheme livecoding, animation, games and plants with Dave Griffiths [UK] at pickledfeet
-
-http://1010.co.uk/images/3613333895_63b4215b5d_o.png
-
-In this workshop you will find out about the emerging art form of
-livecoding and learn how to write simple scripts to create animations in
-3D space. After an introduction to the scheme programming language and
-how to use it to build shapes and animate them, you will be let loose on
-prototype game code for groworld - a game still in production which
-takes elements from guerilla gardening, permaculture and plant growth.
-
-No previous programming experience required. Interest in games and
-plants a bonus :)
-
-Please install fluxus prior to the workshop, which you can find here:
-http://www.pawfal.org/fluxus/packages/
-
-Windows version not recommended at present due to instability, an
-alternative is to use a bootable CD linux distro such as this one
-which will be made available on the day: https://devel.goto10.org/puredyne
-
-Details: http://www.pawfal.org/fluxus/

-
-*** July 11th 1PM: Archaeological geophysics fieldtrip [location unspecified]
-
-http://1010.co.uk/images/ft1.jpg
-
-The pick was [then] used to hammer on the surface, and by this means,
-the Angle Ditch was discovered. The sound produced by hammering on an
-excavated part is much deeper than on an undisturbed surface, a
-circumstance worth knowing when exploring a grass-grown downland,
-though not applicable to cultivated ground.
-
-[Augustus Pitt Rivers. Excavations in Cranborne Chase. Volume IV. 1895]
-
-Geophysical techniques for archaeological prospecting imply a certain
-"seeing beneath the soil," a divination which is akin to scrying
-defined as looking within one medium in order to envision an other
-matter or time. Such techniques frequently involve the examination of
-electromagnetic phenomena mapped to location, and a search for
-anomalous disturbances of local fields. Acoustic and geochemical
-methods of examination can also be employed.
-
-The fieldtrip will examine various approaches to this divining, for
-example electromagnetic field strength measurement and magnetometer
-surveying, to assess an important, as yet unspecified Berlin location
-to be revealed on the 11th of July.
-
-Meeting at 1PM [_____-micro_research] to journey to unspecified
-location.
-
-Contact m@1010.co.uk to reserve a place. Free (travel costs not
-included).

-*** July 18th 2PM: Neanderthal Vocal Computer with Derek Holzer
-
-http://electro-music.com/forum/phpbb-files/img_4225_177.jpg
-
-This workshop combines three of the basic building blocks of the
-longer Neanderthal Electronics workshop (TL072 op-amp comparator, 4093
-gated oscillator & LM386 audio amplifier) to create a very crude,
-caveman-style analog computer for the processing of vocal input
-through a microphone. Participants will learn some analog and digital
-electronics basics to create an experimental prototype on the
-solderless breadboard, then recreate the circuit with permanent
-connections. They are also expected to bring their own box, case or
-other object in which to construct the final circuit. The last part of
-the workshop will touch on how this circuit can be expanded later on
-to include all kinds of mixers, modulators, distortions and filters
-through the use of other cheap, easily obtained parts.
-
-For more information and videos from the Neanderthal Electronics
-workshops, see:

-handicraft technique is mixed with DIY analogue electronic and
-soldering.
-
-You can build a little autonomous analogue sound device or a minimal
-analogues solar robot and seal them in molten schmelzolan plastic
-forms. Ornamental singing plastic discs for window applications or
-kitschy kinetic objects (for windowsills or ohp's) can be
-created. Electronic know-how is not required and all self builded
-creatures can be taken home.

+Geophysical techniques for archaeological prospecting imply a certain
+"seeing beneath the soil," a divination which is akin to scrying
+defined as looking within one medium in order to envision an other
+matter or time. Such techniques frequently involve the examination of
+electromagnetic phenomena mapped to location, and a search for
+anomalous disturbances of local fields. Acoustic and geochemical
+methods of examination can also be employed.
-In this workshop you will find out about the emerging art form of
-livecoding and learn how to write simple scripts to create animations in
-3D space. After an introduction to the scheme programming language and
-how to use it to build shapes and animate them, you will be let loose on
-prototype game code for groworld - a game still in production which
-takes elements from guerilla gardening, permaculture and plant growth.
+The fieldtrip will examine various approaches to this divining, for
+example electromagnetic field strength measurement and magnetometer
+surveying, to assess an important, as yet unspecified Berlin location
+to be revealed on the 11th of July.
-No previous programming experience required. Interest in games and

+** July 4th 2PM: workshop: Fluxus - Scheme livecoding, animation, games and plants with Dave Griffiths [UK] at pickledfeet
+http://1010.co.uk/images/3613333895_63b4215b5d_o.png
+
+In this workshop you will find out about the emerging art form of
+livecoding and learn how to write simple scripts to create animations in
+3D space. After an introduction to the scheme programming language and
+how to use it to build shapes and animate them, you will be let loose on
+prototype game code for groworld - a game still in production which
+takes elements from guerilla gardening, permaculture and plant growth.
+
+No previous programming experience required. Interest in games and
+plants a bonus :)
+
+Please install fluxus prior to the workshop, which you can find here:
+http://www.pawfal.org/fluxus/packages/
+
+Windows version not recommended at present due to instability, an
+alternative is to use a bootable CD linux distro such as this one
+which will be made available on the day: https://devel.goto10.org/puredyne
+
+Details: http://www.pawfal.org/fluxus/
+
+Cost: 10 euros (including food).
+
+Please email m@1010.co.uk to reserve a place (strictly limited)

+** July 5th 8PM: performance: Fluxus live coding with Dave Griffiths and all participants at General Public
+
+Dave Griffiths is one part of Slub: Slub sound emerges from slub
+software; melodic and chordal studies, generative experiments and beat
+processes. Process-based sonic improvisations; live generative music
+using hand crafted and live coded apps, scripts and l-systems in
+networked synchrony. With roots in UK electronica and tech culture,
+slub build their own software environments for creating music in
+realtime. Only custom composition and DSP software is used. Everything
+you hear is formed by human minds.
+
+Slub project their screens so that the audience are able to appreciate
+their live software development process, which does not adhere to
+industry quality control standards. They communicate using OSC over UDP
+and eyebrow gestures. The output ranges from extra slow gabba, through
+intelligent ambient to acid blues glitch.
