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 of my songs: Room of Posers and Sex Machine.
Rings in the Rock
This slice of rock came from a granite boulder found in a stream near Karamea South Island [New Zealand] west coast. The rock formed 400 million years ago. The circular patterns are the work of minerals which crystallized in spheres around a central nucleus.
This really amazed me. A few years later, I started reading The Process of Creating Life you see this pattern recurring in nature. THis also reminds me of the Belousov-Zhabotinsky reaction non-equilibrium thermodynamics, resulting in the establishment of a nonlinear chemical oscillator reaction
And more recently, pictoscribe turned me on to Li , Dynamic Forms in Nature by David Wade

Or, "how to get a 1.3V rechargeable battery cell to illuminate an L.E.D."
A brilliantly simple idea (Google is your friend here in you are unfamiliar with the idea)
Makes a perfect load bank to help keep Li-MH batteries in good shape.
The load on the cell is about 20mA in this experimental lash-up. When the LED is extinguished, the battery is completely exhausted.
The silicon NPN oscillator transistor is a recycled component from somewhere, as is the ferrite toroid.
The LED is a remnant from a junked Christmas tree lighting set.
A little steam engine made from plumber's pipe, car brake pipe and scrap brass/steel.
It spins round really fast with a little meths burner going under the boiler.
It is bolted to an old meccano base.
It took 3 men to man the system. One on the screen reading out the co-ordinates; another plotting; and a third recording. I'm the guy on the right . . .
Immediately adjacent to World-famous Stanford University, Palo Alto is a wealthy community with some of the highest property values and highest education levels in the United States. Silicon Valley started here, with Professorville being the home of Russell Varian, coinventor of the Klystron (energy beam amplifier) and the site of Lee de Forest's creation of the vacuum tube and electronic oscillator. In 1939 David Packard and William Hewlett famously created the audio oscillator in the garage of their home, leading to the formation of HP. Other companies that remain headquartered here include Space Systems/Loral, VMware, Tesla Motors, Ford Research and Innovation Center, PARC, IDEO, Skype, Palantir Technologies, and Houzz. Its large 1930s-style downtown is known to be popular with Stanford students and venture capitalists. I recently saw a filming of an episode of Mike Judge's "Silicon Valley" filmed here, a show which is accepted to be a frighteningly accurate depiction of the tech industry.

... a measurement panel appears on the left, for monitoring the power supplies from the Motor Room. It’s not clear but it seems that the left-hand frame is the Extra High Tension (EHT) rectifier and filter unit. The two central frames seem to be the Master Oscillator and Modulated Amplifier. The right-hand frame appears to be the Modulator, with four MT7B triodes visible (along with a spare triode on the floor) ...
Here is the front view of a time code generator I picked up at the electronics flea market.
The manufacturer is unknown, and the PC board is not marked with any manufacturer logo or information. Anyone recognize this?
The device was DOA when I first got it, and the culprit was a leaky film cap in part of the synchronizing oscillator circuit. This thing is quite complicated inside, and it uses a combination of TTL and DTL ICs, along with LM301 op amps, discrete transistors, and a few JFETs.
Oven controlled xtal oscillator (top left) and modulator shelf at bottom of unit (all those presets!).
Seven FETs, fourteen resistors, and seven capacitors are added to make a simple ring oscillator circuit. The copper framework both supports the parts and acts as a ground plane. The outer ring is positive, the inner negative. Plastic sleeves are slipped over some leads to prevent shorting.
This was our rest room (open door). 24-7 was our hours of business! I still like to say that "Western Europe slept safely while we watched the skies at night".!! Sounds great! Getting back to more mundane matters, I can't remember the loo we had. No doubt a "natural" one. Certainly nothing "en suite"!
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”.
Here's a World War II-era oscilloscope. These early devices lacked a lot of features that come standard on modern instruments--basic things like trigger circuits and calibrated reticules.
There were still many measurements that could be taken with a device like this, such as the following:
* Comparing some input frequency to a reference frequency, or a ratio thereof.
* Amplifier distortion (plotting the voltage transfer curve of the amplifier)
* Measuring the hysteresis loop of an inductor (BH loop)
* Measuring the peak-to-peak voltage of an AC signal (by comparing to a reference)
* Checking RF modulators and demodulators
It must have been a lonely existence for the WT operator. It was a sad occasion for me. The whole area is now covered by a modern industrial site. I was there last year (2015), and I took a few photos then. Maybe I'll show them one day . . . .
Thanks for looking through these old photos! I have never forgotten my time in Germany, the memories of which have remained strongly with me all these years . . . .

What I like about this kit is the large and sturdy metal chassis with quality electronic components, including a large oval speaker. The person who assembled did a great job even though there were some mistaken connections in the audio output stage and in the oscillator stage, so I proceeded to correct the faults and now works very well. The cabinet has some damages due to the use and the passage of time, very common to be made of compressed and coated board.
This is our TinyG Stepper Controller Board. I tossed some code up on the xmega to test inputs from these "encoder ports" All I am doing is putting 3v onto each pin and it turns off the led that corresponds to the port.

The ramé-hart Oscillator (p/n 100-28) provides precisely controlled periodic oscillatory deformation of sessile and pendant bubbles and drops in order to allow for the measurement of surface dilatational elasticity and viscosity using the axisymmetric drop and bubble shape method. Designed to sit inline between the Automated Dispensing System and the final dispensing tip or needle, the Oscillator is motor-driven and fully software controlled using ramé-hart DROPimage v2.4 or higher software. The Oscillator requires an Automated Dispensing System and current-generation Model 250, 290, 500, or 590 or a legacy system that has been sufficiently upgraded. DROPimage Advanced includes a methods editor which incorporates an array of parameters for controlling the frequency, acceleration, timing and steps of the oscillation commands. This product includes (1) one year parts and labor warranty.

Trips to Hamburg were not all that regular, although there were lots to see and do. In those days it enjoyed a wonderful sleazy night-life . . . mostly gone now, "sanitised" by interfering faceless Brussels' bureaucrats!! This is the Alster, a huge lake in the centre of town, drinking a coke by the looks of it. It might have been a Cuba Libre, the favoured drink of the day! I also managed to get a weekend break to Copenhagen.

LEFFER VRM 2500 OSCILLATOR
The Leffer hydraulic casing Oscillator has over 8 million ft-lbs of torque and 580 tons of extraction force. This
machine is capable of drilling over 200 ft deep with a 2.5M oscillator casing.
This machine is used in caving soils where the bore hole requires casing to the bottom of the hole.
Testing the electronic Doppler "phantom" wot I built as an RA in Medical Physics. There are jobs you love ... and there's working in a crappy basement in an old hospital for a year.
Bob fired up the oscillator and it swings into the night over another sleeping Metra switcher at Western Avenue.

- Enhancer
- Modulation Oscillator
- Multi Delay
- Fader-Panner
- Dynamic Noise Filter 2
- Pro-Gate 2
- Power
Info:
Mid 1980's Tantek, Tanrak Studio Effects Rack which was available in kit form or ready built. On the face of it, they're simple analogue effects - a bit old-fashioned, really - but that's the charm of them. They've perfectly useable and immediately accessible, so you'll have great fun fiddling with the settings - try sweeping the EQ frequency, or riding the delay time for on-the-fly munchkinisation, for instance.
Even better, you'll find new ways to patch the modules together. Everything - in, out and sidechain - is accessible from the rear panel (there's a default path from left to right across the rack if you don't want to use patch cords) so you can create LFO-modulated delay effects, frequency-sensitive compression ... you think of it, you can do it.
STEREO COMPRESSOR/LIMITER - A high quality stereo comp/limiter with variable input, slope, attack and release controls, and a switched 'key' input that can link both channels...handy for de-essing, ducking etc. It's pretty much 'invisible' when used as a limiter, only squeezing when the threshold is crossed (depending on the ratio setting). Great for laying vocal tracks, mix thickening, fattening up drums, percussions and bass. In fact, it can make anything sound 'phat' but still retains that important top-end clarity.
MULTI-DELAY - This exciting module opens the way to high quality time domain effects including ADT, chorus, echo, vibrato and reverb. It features a built-in limiter, auto-optimising bandwidth, true spatial stereo outputs and multi reflection reverberation.
MODULATION OSCILLATOR - A CV modulation source whose features include sinewave output, variable duty cycle, key or CV controlled depth, triggerable sweeps and two independently variable outputs. Used with the muli-delay to create chorus, flanging etc.
DYNAMIC NOISE FILTER - An effective single ended, easy to use, stereo noise reducer which will be found invaluable in any home studio set up to enhance the signal to noise ratio of outboard effects including those which exhibit digital quantisation noise.
STEREO NOISE GATE – This is a pro noise gate. Variable threshold, attack, release controls, with a 'hold' timer control to keep the gate open for a predetermined time after triggering from the switched 'key' input on the back panel. Good sensitive threshold control, it really enables you to home in on that elusive area between the sounds you want and the sounds you don't, with the threshold setting staying put and not 'drifting'.
POWER SUPPLY MODULE – Supplies regulated 12v DC power to all of the above modules via the 240v mains lead. It's got an on/off switch and an LED. It sits at the end of the rack.
