LCF (inductance, capacitance, frequency) meter using arduino (LCDuino), a local lm311-based oscillator (NOW shown), a pair of AA batteries and an adafruit dc/dc 5v upconverter and an adafruit xbee hosting board for wireless data logging.
A Voltage-Controlled Amplifier (VCA) made from three BC549 NPN transistors and three BC214 PNP transistors. It's a Gm Cell with variable current followed by a simple op-amp.
The input is rigged up to an HP 4204A Oscillator with a 3310A Function Generator supplying the modulation signal. Output goes to a Tek 5440 analog oscilloscope and an X-Mini capsule speaker.

the rigol scope is the 'famous one' that can be modded from 50 to 100mhz just with a firmware upgrade. I plan to do that eventually. to the right is a cheap power supply that was on sale and I bought it on impulse ;) one can never have enough small lab supplies, now can one?
Researching the impact of frequency on the operation of the alternating current motor, Tesla observed that the efficiency of the motor decreases at higher frequencies, but also that less iron is required to manufacture it. This observation led him, as of 1888, towards the research of high frequency phenomena in devices without iron in their magnetic circuit. In early 1889, he started the design and construction of the first high-frequency devices.
In 1891, he invented a device that he called the oscillator of high frequency currents. Tesla's oscillator device consists of high-frequency coreless transformer and discharge.
Now with a name and probably a final front panel. We are taking pre-orders for Macbeth's new X-Series Dual Oscillator in Eurorack format (see link below). The price is $1295 plus shipping, delivery time is approximately 5 weeks. The first module run will be small. LINK: www.analoguehaven.com/macbethstudiosystems/xseriesdualosc... .

Man's Best Friend - Rex, our guard dog! He was also a very well-fed dog! The night shift were always fed about 10 p.m.. The duty driver would head down to the mess hall and pick up a tray of fried eggs, bacon, sausages (never Wurst by the way), and fried potatoes. Always very appetising! If there were any left-overs, and invariably there were, Rex could be relied on to scoff the lot!!

A nice looking radio.
Unfortunately it looks better than it performs!
But it's only got four valves, so maybe I'm being a bit harsh!
However I think the manufacturers really missed a trick with this radio.
I reckon (with 20:20 hindsight) that the addition of a tuned RF stage (to improve image reception and isolate the oscillator from tha antenna), an extra IF stage (to improve selectivity) plus a product detector (to improve the demodulation of SSB signals) for a few more pounds on the price, would have produced a much more capable receiver for a still reasonable price.
At the time the Japanese were moving in on this market with much classier radios, albeit at a higher price.
I bet a lot of people bought these only to be disappointed with the performance.
The price did reflect this, so on a "bang for buck" basis it was probably reasonable value, but the advertising created the impression that it was somewhat better, describing it as an "outstanding general coverage communications receiver", which it certainly wasn't!

Designed to fit into the drive housing of the old-style Meade GEM mounts. With addition of a rotary switch and some push buttons it can also do lunar, solar, and E/W (10%) guide/centering. Runs off 10-14 volts.
Katerina Undo Creatures Cluster, 2014
Creatures Cluster is an endless combination of living members, composed by miniature robots that live autonomously, receiving their energy from solar cells and generating a variety of soft sounds and tiny movements. The Creatures are developed with two simple analogue oscillator circuits, inspired from the nervous system of organisms. Every module is special and unique and it is impossible to build exact equal. According to the interaction that occurs between them, clusters/systems are developed that organically interact with each other in a reciprocal way. The sculptural and auditory nature of the synthesis – radiation of the chaotic – refers to the functioning of a nervous system, as well as to systems of social cooperation and alliances.

The disused control tower, taken a few years earlier when the station was operational. I think it was 1953 when RAF Lüneburg closed down. Another little scam which was ongoing when I arrived. If you were a non-smoker it was possible to use your allowance to buy cigarettes cheaply; then a courier would go up to Hamburg with a caseful and sell them on the black market!! Tut, tut!! However, that little caper stopped when the courier got demobbed, and no-one else was interested in taking up the job. There was also an elderly local woman who was happy to take on ironing (shirts) for a few DMs. A perfectly amicable arrangement . . . and she also was well paid!!

Acoustic Botany presents a garden for listening. Benqué suggests a combination of plant manipulations: from grafting and selective breeding methods to genetic manipulation and synthetic biology, to make flowers and plants produce sounds. What if you could listen to a garden, instead of looking at it? What would be possible soundscapes? What would the experience be like? But also, how would greenhouses be adapted? What set of rules would one need to take into account?
By presenting a fantastical acoustic garden, a controlled ecosystem of entertainment, Benqué aims to explore our cultural and aesthetic relationship to nature, and to question its future in the age of Synthetic Biology.

The entrance way to our site. Wot no gates and no fences!! The problem was that although there was a guarded front entrance to the camp, no one bothered about the rear. Beyond the airfield were woods which no one guarded. You could walk to Siberia if you had a mind to. Well, maybe not, the Iron Curtain would have stopped you!

The clock is assembled in a semi-enclosure made from old cassette tape cases. (Thanks to Denis for this idea.)
I replaced the BoArduino's 16MHz oscillator with a 32768 Hz watch crystal for better timekeeping. But there's something wrong with the crystal - it doesn't keep proper time. I've mostly adjusted for the inaccuracy in the clock's firmware.
The hardware & firmware are partly based on Adafruit's Ice Tube clock.
How does your quartz watch keep time? With one of these marvellous little oscillators, beating time 32768 times a second.
See the companion photo to get an idea of the scale.

Should it be called the Penultimate?
LPF board for 80m fitted, unboxed but functional.
A 47R 2W resistor forms a test load.
The can of the oscillator unit on the DDS board has been "roughed up" in preparation for having some kind of heatsinking applied to it, the exact form of which has not yet been decided.
I haven't even decided whether it is needed or not. The received knowledge is that heatsinking improves the frequency stability of the unit which is a critical feature of equipment intended for QRSS use.
Cutting-edge stuff!
The microcntroller is an Atmel ATMega168
New oscillator, shaft, collar, and set screw.
This is for my SP-15
Made by my local trusted machinist.
A Made in Hoddesdon England Lyons SQ-10 square/sine Oscillator (Top) with a french made HAMEG Oscilloscope HM-307 (Bottom)
Both say Lab-2 on them but not were lab two is??? bought at dene park car boot Hull 2006
Here is the 1.0-1.5 MHz VFO in its box complete with tuning capacitor.
No thermal optimisation has taken place yet, but the oscillator tunes from just below 1.0 MHz to just above 1.5 MHz, so it is ready for this process. I am considering trying a "huff and puff" stabiliser.
Unfortunately the variable capacitor has spent so long in my junk box that it isn't in very good shape (it's microphonic) but I am hoping that with a bit of attention to the bearings, this may improve.
The perf. board top left has the 2-stage buffier amplifier, and the 6V regulator for the oscillator itself.
The tuning knob is just a temporary affair.
A Westinghouse Electric Fan, dating from about 1910 -1915. This one is 12", with six brass blades, brass cage, and an oscillator. As long as you keep them lubricated, these 100 year old fans are pretty much indestructible.
Virtually pristine condition. This is my second 405 line set. It's a 1956 model.
It was bought in an antique shop in Windsor, London and sent to Australia in a tea chest.
Tuner is 13 channel and superhet receiver is used. Line oscillator has AFC. AGC is mean level from sync separator grid. It's a very 'text book' circuit for a 405 line set.
Normal 300mA heater 7 and 9 pin Philips/Mullard valves are used.

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.”
