Our first home was the old Fire Station for the now-defunct airfield. We were there for about 6 months until a small detachment of Americans came along and fancied the quarters. We had to find a new home. Say no more!! A bit more about our unit. There were about 12 of us in all, including a sergeant (in charge and in married quarters), 3 corporals, 1 fireman and a wireless operator (WT). NO bull, NO parades, NO inspections, and with the exception of the cpls and sgt. most were National Servicemen. As said earlier this was a detached unit. Our main base was 245km (152 miles) away to the south-west at RAF Sundern, in Gutersloh.

An original Interactive Art Sculpture designed and created by MRISAR’s R&D Team.
"Touch Spectrum" Directions: Place one hand on each metal plate and the Touch Spectrum will react by creating sounds and light patterns. Or place one hand on a metal plate and have another person place one of their hands on the other plate and then touch each of your remaining hands together. Try touching it with only a finger tip, then place your whole hand on the plate. Notice how the sound deepens as your hand covers more surface. This occurs because your body is the conductor for the electrical current and the more surface you cover the larger the conductive pathway is. This increase in conductivity creates deeper tones. This exhibit was designed for public safety!!
The sculpture conducts a small electrical signal, which turns on an oscillator, which creates sounds. As more users touch the plates the sounds develop deep tonal qualities that are reminiscent of musical notes. It also illustrates touch switch technology, energy conversion, photovoltaic and photonic science, electrical conductance and oscillator theory.
In 2010 MRISAR, (a business that has Designed, Fabricated & Marketed the Earth’s Largest Selection of “Internationally Renowned & Awarded, World-Class Robotics Exhibits & Devices”; and “Hands On” Scientific, Technological & Interactive Art Exhibits), purchased a disused school on the plains of North Dakota and relocated to it. Profit from their International Exhibit Sales helps fund their Humanitarian R&D and the transformation of the 36,000 sq. ft. complex, surrounded by 10 acres in North Dakota, into a World-Class “Interactive, Robotics, Technology, Invention, Art & Nature Center”.
Description of MRISAR’s “Interactive; Robotics, Technology, Invention, Art & Nature Center”.
1- Our 7,000 sq. ft. Exhibit Hall will feature; our standard line of interactive robotic & technology exhibits that we sell to Centers world-wide and our exclusive collection of robotic exhibits & devices that we will not sell to anyone else. Our talking Rail Robot Guide will lead visitors through the exhibit hall. Interact with our innovative, lifelike, futuristic, Robotic creations. Examples; Play with & feed Artificial Life forms in a Robot Zoo! Challenge robots with your human intelligence! Interact with otherworldly artistic, interactive, robotic sculptures! It will also feature Responsible Technologies.
2- Our Art Galleries will display the hundreds of pieces of family friendly, original 2D, 3D and Interactive Art that our team has already created, plus have revolving Family Oriented Local Artists Exhibitions.
3- The surrounding 10 acres is slowly being transformed into an Outdoor Interactive Art & Nature Area that will be filled with paths, trees, gardens and kinetic & interactive, solar & wind, technological art sculptures. The emphasis is edible, medicinal & organic landscapes that promote sustainability & health. As of 2015 over 3,000 edible and medicinal trees and shrubs have been planted.
4- We will provide “Special Tours” of behind the scenes areas. Examples are; (a) our Humanitarian & Environmental Research & Development Think Tank Invention labs that feature our R & D Projects. (b) the actual workshops where the attractions are created (similar to visiting the workshops & creations of Jim Henson’s creature shop). (c) a behind the scenes view of the production studio for the web series we are creating called the “Mysterious Lab of Robotics” (our robotic version of “Bill Nye the Science Guy” or “Beakman’s World”). (d) a chance to meet MRISAR’s internationally renowned robotics R & D team. A four member family team who since 2000 has designed, fabricated & marketed the earth’s largest selection of world-class robotic exhibits. The 2 youngest members joined the team as preschoolers.
5- “Public Enrichment Events”. Examples are; (a) special overnight events called “A Night with the Robots” (available no-where else in the world). Families can make reservations to spend the night on the center floor in sleeping bags or cots and experience special robotic demonstrations in a futuristic atmosphere. In recent years “A Night at the Museum” events have become very popular and highly accepted. (b) special classes on robotics for the general public. (c) Robotics Competitions. We are already providing technical assistance to teachers and academic establishments (both in the state and outside of the country), that are trying to enter robotic competitions, but lack the knowledge to fully instruct and inspire their students. A natural progression for this, once we are open for tourism, would be to offer to hold regional, national and international competitions at our location. (d) International conferences regarding Robotics and Beneficial R & D Conferences. (e) Collaborations, enrichment classes and internships in enhanced technologies with higher academic establishments; combining elements such as Cybernetics, Bionics, Mechatronics, Autonomics, Animatronics & Teleoperation.
6- Admission will be free to the underprivileged. We hope to inspire the upcoming generation to create careers in responsible technologies that improve the quality of life.
7- The proceeds from the Center will help fund our R & D and further our creation of a “Prototype Environment, low cost, low impact, self-sustaining, alternative energy powered, Humanitarian & Environmental Research & Development institute with Think Tank Invention labs”. Our purpose is to invent and present responsible, low cost and easy to implement, beneficial humanitarian and environmental based technologies and methods that assist with social, ecological, sustainable and economic solutions. Accomplishing the prototype environment alone requires research & development of new technologies & improvement of existing technologies.
We have Designed, Fabricated & Marketed the Earth’s Largest Selection of "Internationally Renowned & Awarded" World-Class Robotics Exhibits & Devices; and “Hands On” Scientific, Technological & Interactive Art Exhibits. Our innovative, interactive, inexpensive, durable & easy to maintain creations incorporate interactive technologies & designs for people with disabilities and other special needs. We also provide our own Educational Kits & Materials for K thru 12/College & University level curriculums.
Our Exhibit Sales Customers include World-Class Science Centers, Museums, Universities, NASA, Royalty, Foreign & Domestic Governments, the Film Industries for inclusion in media productions, etc. We specialize in Cybernetics, Bionics, Mechatronics, Autonomics, Animatronics & Teleoperated devices.
Our Humanitarian & Environmental Research & Development has been presented before and/or published and awarded by: the United Nations, NASA-Emhart, Stanford, Cambridge, ICORR, ROMAN, IEEE, Discover Awards, International Federation of Robotics (IFR), etc. Our 1990's circa, original innovative R & D in "Facial Feature Controlled Technology" and "Artificial Sense of Touch Technology" (Adaptive Technology prototypes for the disabled), has helped pioneer those fields! We were the only company in the world to be awarded an entire chapter regarding our work in the International Federation of Robotics (IFR) “World Robotics; Service Robotics, 2011”.
The Atari Punk console built up with standard pots to control the base oscillator and the secondary divider. Screw terminals and a 2 way jumper allow addition of external CV sources or a LFO to create a wide range noise maker. Coming soon to Tindie and ebay form Electro-Resales.
The '2313 is my favorite AVR and these target boards are great. Cheap and capable. I used the internal oscillator and was able to keep the USART pins open for debugging or future expansion.
Since I had an ATtiny2313 but no shift registers, this AVR is using its built-in 8-bit shift register to perform the mundane task of emulating the 16-bit parallel-in, serial-out shift register found in Super Nintendo controllers. Only 12 bits are connected or connectable to buttons. The AVR gives me built-in pullup resistors and a secure place to solder all the wires. This part has the perfect pin count for this task.
The ATtiny2313 costs about $2.00 in single quantities. 8-bit shift registers (you will need two chained together) cost about $0.55 in onesies. If you don't feel like chaining two 8-bit shift registers together, you can get all 16 bits in a single part for about $25.00!
The target board is from evilmadscience.com/tinykitlist/112-tiny2313

It's the devil's workbench. Underneath are oscillators and other stuff used for fixing tvs and electronics. and now the top is covered with mail-art supplies.
Dad told me that he's been sending mail art to anybody he can think of, including his young neighbors. He's a proselytizer!
A detail from Tesla 3-6-9. This is where you type in your message. The guy in the middle picks up your message from the output of the touch screen (the screen is not seen in the picture, as this picture only show the inner workings of the machine). If you dont want to, or are unable to read or write read, you can also speak your message through the microphone mounted in the center bottom. He then translates the message, using the big ring of keys (the many black squares), which writes in the most commonly used alphabet in our universe. When the message is translated, he converts it into wave form, using the synthesizer like instruments located around him. They are mostly based on the Revox B77 tape recorder (for a physical backup of the message, just in case), the Memory Moog (wording and pronounciation), and the EMS VCS-3 (mood, expression and additional effects). Then the message is sent out the Big wire on the bottom left, to the transmitter.
The incoming signal, comes through the middle one of the big black wires. The guy in the middle again uses his "synthlike" instruments to translate the message into a language we can understand. The message is usually sent down and through the screen input/output, but it can also be sent through a speak synthesis. It is your choice if you Want to use the speaker in the bottom left, or the mini jack output at the top.

Oscar and Sarah gave me a few minutes to put some of the finishing touches on the 4SQRP HF Test Set I assembled a few months ago. It's really a nice tool. I will use the frequency counter and crystal oscillator the most, probably. But there are lots of other tools built into this nifty little outfit.
The underside of the PCB of the Limrose logic tutor. Switches and oscillator are on the left, LEDs on the right. Note the decoupling capacitors on the power supply tracks near the middle of the board.
LCF (inductance, capacitance, frequency) meter using arduino (LCDuino), a local lm311-based oscillator (not shown), a pair of AA batteries and an adafruit dc/dc 5v upconverter and an adafruit xbee hosting board for wireless data logging.
Five drone voices whose pitch can be tuned by the massive knob at the bottom or by an LDR at the top. The medium size knob is the speed of essentially an LFO that sends a little "blip" to the volume of the voice below. These create a fun poly-rhythm/phasing between the five voices. The speed of this LFO can also respond to an LDR at the top.
The whole thing is housed in some beautiful walnut, finished in Danish oil with a plywood face.

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!
