With a tide of change sweeping the globe and the socio-political landscape increasingly subject to crisis and change, automation, algorithms and AI are playing an influential role within this paradigm.
So who are we to trust? This panel of artists and technologists explores the complex anthropomorphic relationships we have with gadgets and robots and how this shapes our world view. The panel will include Kirsty Hassard, Jan de Coster, Professor Ruth Aylett and Julien Ottavi.
About the Panel
Kirsty Hassard is curator of the Hello, Robot. exhibition at V&A Dundee, which investigates how robots are helping to shape the world we live in, showing how design is a mediator in this relationship between human and machine. A relative newcomer to the world of robotics, she was previously assistant curator of Furniture, Textiles and Fashion at the Victoria and Albert Museum and was assistant curator on the Balenciaga: Shaping Fashion exhibition. She has an MA in History and a MLitt in Dress and Textile Histories from the University of Glasgow. She has lectured and published on the relationship between print culture and fashion in eighteenth century London and Paris.
Jan De Coster grew up with a vivid fascination for physics, science fiction stories and hacking stuff. In college he realized that all the stories around science were often far more appealing than the theory behind them, and in the mid 90’s he started on his first multimedia productions.
In 2007, Jan founded Slightly Overdone Robots, a production studio which explores the horizons of Human-Robot interaction, where he has been making interactive installations and Robots ever since.
On his quest to make Robots a more widely accepted creative medium, Jan is now teaching young and old about building Robots, focusing on the design and the process, and the way they make us feel.
In the late 90’s Jan De Coster started making interactive projects and physical installations, with a strong focus on storytelling.
Jan has a background in physics and engineering and worked at different Advertising agencies at the beginning of his career. In recent years, he started teaching and giving workshops and lectures about innovation, creativity and especially robots. These workshops have brought him to visit and engage with creative communities from Qatar to Mexico. His robots have been travelling the world as a part of different exhibitions and his social robots explore the meaning of human-robot interaction.
Prof Ruth Aylett – Ruth is Professor of Computer Sciences in the School of Maths and Computer Science at Heriot-Watt University. She researches Affective Systems, Social Agents in both graphical and robotic embodiments, and Human-Robot Interaction, as well as Interactive Narrative. She led three EU projects (VICTEC, eCIRCUS and eCUTE) in the period 2001-2012 applying empathic graphical characters to education against bullying (FearNot!) and in cultural sensitive (ORIENT, Traveller, MIXER). She also worked as a PI in the projects LIREC (investigating long-lived robot companions) and EMOTE (an empathic robot tutor). She led the EPSRC-funded network of excellence in interactive narrative, RIDERS. She is currently PI of the project SoCoRo (Socially Competent Robots) which is investigating the use of a mobile robot to train high-functioning adults with an Autism Spectrum Disorder in social interaction. She has authored more then 250 referred publications in conferences, journals and book chapters, and has been an invited speaker at various events, most recently AAMAS 2016.
Julien Ottavi – Doctor in Arts, Composer, Artist, Curator. A mediactivist, artist-researcher, composer / musician, poet and tongues destroyer, experimental filmmaker and an architect, founder and member of Apo33, Julien Ottavi is involved in research and creative work, combining sound art, real-time video, new technologies and body performances. Since 1997, he develops a composition work using voice and its transformation through computer. Active developer of audio/visual programs with Puredata, he has also developed since many years DIY electronics (radio transmitters, oscillators, mixers, amplifiers, video transmitters…etc) in the perspective of knowledge sharing on technological development. Main developer for the Gnu/Linux operating system APODIO for digital art and A/V & streaming diffusion. His practices is not limited to the art spheres but crosses different fields from technological development to philosophy / theoretical research, biomimetic analysis, robotics and experimentation. For many years he reflects on the relations between experimental practices and collective practices within the creation of autonomous collective groups, putting in question the authorship strategy of the “art ideology.”

The hands of Oliver Chesler, The Horrorist in his recording studio in Berlin, Germany using his Roland SH3 synthesizer.
The Roland SH3 was produced in 1974. It is more rare than the SH3A which was put into the market after Moog sued Roland for the original SH3's filter design. This is one reason the Roland SH3 sounds so incredible. Rumor has it that less than 100 of these were ever made.
You can hear pure Roland SH3 accompanied by an Electrocomp-101 in two songs from The Horrorist: Room of Posers and Sex Machine.

A few documentation shots of the multi oscillator, light reactive synths I've been building for various performances as part of Sanctuary 2015. They use the amazingly hardy perennial favourite IC, the 40106 CMSOS Schmitt trigger.
There are also a couple of not synths, but percussive instruments made from jars, piezo electric contact mics and m3 nuts and a silver dollar respectively,
After replacing those 2 burnt resistors, the loudspeaker drive amplifier seems to work. Here it is connected to the speaker and a test signal (from a test oscillator PCB, not part of the machine), is injected on the pin that would connect to the slider of the volume control. Yes, I got a beep from the speaker.
This is the replacement hardware. The core is a PIC18f4550 controlling everything with a 20Mhz oscillator to supply the PLL for the 48Mhz required to run USB should i ever get round to implementing that. The CPU runs at 8Mhz from the internal osc. There is a MAX232 to drive the serial port and some transistors to switch relays for the spindle and that is about it. the 9 pin plug floating there is just to allow me to debug the board when it is not in the machine. The screw terminals will be for the motor and the spindle encoder but the encoder is not implemented in code yet so I haven't connected it. Some fly back diodes for the relays, caps for the MAX232 charge pumps, transistor base resistors, LEDs for debugging, ICSP plug and some wire make up what is left. Not really all that much there. I will probably add another transistor and 2 resistors and a cap to this to amplify the PWM signal since the PIC gives out 5Vpk-pk and the PWM in the control box needs 0-10V in. (I know its a bit silly generating an analogue voltage from a PWM output only to use it to control another PWM drive but this way it is a direct board swap.)
This is according to Mr Carlson's schematic, and it works! (See previous image.)
Power rails are +/- 15V.
Op amp is TL072CP.
Component values are chosen for ~ 1kHz frequency.

From VintageSynth.com: The GR-700 is a stomp-box guitar synth with the same synth engine as the JX-3P. The G-707 is the flashy guitar controller which connects to the 700 via 24 pin cable. On the 707 guitar are knobs for the cut-off edit and LFO modulation! So now you can play synth sounds with the guitar instead of a keyboard. Sound-wise it's a pretty good synth. You will need the PG-200 programmer if you want to edit patches more easily. Recall patches by stomping on the foot pedals.
The GR-700 is a six voice polyphonic with two DCO's per voice which means analog oscillators and sounds with digital stability and control. The typical assortment of a resonant lowpass filter, ADSR envelope, LFO and oscillator sections are here with easy and straight-forward programming. The GR-700 and G-707 are used by Cirrus, Tim Skold with MDFMK, Amir Derakh of Orgy, Charlie Singleton of Cameo, T.G.Noyes, King Crimson, Sigue Sigue Sputnik, and Andy Summers of the Police.
1. Product Overview :
XT1511 side is a smart LED control circuit and light emitting circuit in one controlled LED source, which has the shape of a 4020 LED chip. Each lighting element is a pixel, and the intensities of the pixels are contained within the intelligent digital interface input. The output is driven by patented PWM technology, which effectively guarantees high consistency of the color of the pixels. The control circuit consists of a signal shaping amplification circuit, a built-in constant current circuit, and a high precision RC oscillator.
The data protocol being used is uni-polar NRZ communication mode. The 24-bit data is transmitted from the controller to DIN of the first element, and if it is accepted it is extracted pixel to pixel. After an internal data latch, the remaining data is passed through the internal amplification circuit and sent out on the DO port to the remaining pixels. The pixel is reset after the end of DIN. Using automatic shaping forwarding technology makes the number of cascaded pixels without signal transmission only limited by signal transmission speed.
The LED has a low driving voltage (which allows for environmental protection and energy saving), high brightness, scattering angle, good consistency, low power, and long life. The control circuit is integrated in the LED above.
2. Main Application Field:
●Full color LED string light, LED full color module, LED super hard and soft lights, LED guardrail tube, LED appearance / scene lighting

A typical setup for crane-grab-oscillator type of large diameter bored piling; often gone to a depth of 90+ meters in many cases.
Unlike the Kelly Bar / Auger / Bentonite system, this casing-lined method is highly reliable. True rock-to-concrete interface can often be achieved - an essential feature in high quality piles for building of 50+ levels tower blocks.
When you need a pair of 56kΩ resistors, but all you have in the junkbox are high-stability, 2% carbon-composition types from the early 1960s. Which have been desoldered and have short, fat leads. Had to solder on some LED clippings to make them fit the solderless breadboard.
The circuit is a twin-T oscillator that doesn't quite have enough gain to keep oscillating.
This a complete render of an electron tube I got a few years back from an old fashioned electronic store called "Halted Electronics". They have ancient machines dating back to late 1950 to 60 and up era's. Its really cool over there! They have tones of oscillators, meters, capacitors etc. And they have like a buckut-load of Electron tubes (that work) in vintage boxes. I got a cool one thats aprox. 6 inches tall... and here is a fairly accurate model of the tube! (ecsept for the font on the base.) This was a fun and long project. I had to deal alot with glass materials and ray transparency values to get the glass just right. All lit by HDRI.
A spring is stretched vertically, and the lower end attached to a mechanical oscillator (not shown). Standing waves are set up. The coils at the nodes of the standing waves are stationary, so they appear sharp in the image.

Revisiting/Refurbed one of the first synths I ever built.
An atari punk console in a turkish delight box = A wooden knob for each oscillator, push buttons for LDRs and touch points made from pins.
Inside of an example of the first instrument made by Hewlett-Packard, the HP200A oscillator. The tungsten filament of a light bulb (to the right of the top bank of the central structure, a variable capacitor) isn't use for light: it's used as a negative temperature coefficient resistor in a stabilizing feedback loop.

Please ask before use
The NetClock/2 receives and demodulates the WWVB 60 KHz time signal. Once the signal is decoded, the NetClock/2 provides accurate and traceable time data. Or did...
Above is an historical picture, clock locked to WWVB on April 1, 2012.
WARNING: Spectracom receivers extract the carrier from WWVB using a PLL to discipline a local oscillator. The new phase modulation scheme, to be activated by NIST in July, 2012, does not allow carrier extraction... and impacts Spectracom's WWVB products ability to decode time-of-day reliably.
Translation: Netclock/2 will fail. It will unlock from "time sync" and begin freewheeling when the change is initiated. It will become a boat anchor.
The good news: cheap consumer clocks will work better.
