Oberheim OB-8-Capacitor Replacement-Voice Card - These are the capacitors we replaced to fix the tuning problem. The oscillators would not tune very well and were further out when you transpose the keyboard higher and higher. It was also affected by temperature. On warmer days it was worse, on colder days it was almost in tune. After leaving it off for a week it was perfect - for about 10 minutes!

 

This is probably a 14.318MHz crystal resonator, but I was unable to find any data on it other than that it was made by KDS in Taiwan.

 

From what I can find oscillators tend to have other components like ICs inside them, but I do not see any wiring which would indicate there is anything else in this package, so I would guess this is a resonator.

 

It has 4 solder pads and is from an old Dell laptop.

 

Lighting this up was surprisingly hard since the metallurgical lamp from my scope was not able to provide enough light on it's own. I ended up using the small LED I have taped to my 5X objective (intended for observing CPUs) in conjunction with the built-in lamp.

A colleague at work was telling me the other day that his dad used to repair television sets, back when television sets could actually be repaired. His dad had long ago gotten out of the business, and my colleague was in posession of some of his the old equipment. I asked about it, and he said that he had an old oscilloscope. I instantly knew that I just had to see that piece of vintage hardware, and he obligingly brought it to work a few days later. It is still functional, and it's on display in my office at the moment. He'll take it back in a few days, but for now, it's the office novelty. I don't have a signal generator to demonstrate waveforms and such, but there's enough noise in the environment that I can show the 60-cycle hum of the electrical grid, and play all kinds of signal games with it, to generate Lissajous curves and stuff like that. We teasingly refer to it as the "Great Oscillator," and make believe that it's some great oracle of wisdom. We ask the Great Oscillator questions, and it answers by changing its waveform or speeding up or slowing down it's horizontal sync. It's all in good fun, and it's been a blast to be able to play with a wonderful relic of high technology past.

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.

1956 was also the year for Suez and the Hungarian Uprising. There was a great buzz on the camp especially during the former. We thought there was a strong possibility that we would all be shipped off to the Middle East. There were even rumours galore about the arrival of sandy-coloured paint for our vans; even khakis and shorts for Middle East temperatures!. It never came to pass of course, but those National Servicemen who did go were awarded a medal. Actually there was more danger coming from Russia who were always on the make in these situations. We thought too that their intervention in Hungary might have sparked off into something more serious. Maybe just as well nothing happened, or I might not be around today to tell the tale!!

Above - A group of the lads posing for . . . well, whatever. I am the one (the only one) in the second row . . . the good-looking one!!!

This was found inside of a surface mount 40MHz crystal oscillator. I removed the lid by prying it off carefully with a razor.

 

This chip is manufactured by Nippon Precision Circuits (NPC) and was most likely designed around 2008. According to the datasheet, the die has dimensions of 1.31mm x 0.92mm and the aspect ratio of this image is very close to that. The die is 7600px wide, so 1310000nm / 7600px = roughly 172nm/px

 

I have not been able to post as much lately since my university classes are taking up most of my time.

This was indeed home-from-home! Central heating and double glazing. What more could one wish for in the Forces. I could have had a room to myself which was my right when they made me up to a corporal. They always had to have a NCO in charge of the shift in case of problems. From AC2 to AC1 to LAC to SAC to CPL - and I got paid for it - all within a year! The pin-up by the way was Jeanette Scott - I think!

DS1302 chip and a 32.767 khz crystal (small metal cylinder).

 

soldered in to the arduino and using code that I got from tom L. here's my latest:

 

www.netstuff.org/espresso-master/firmware/arduino/

 

v34 of my code has support for reading and (primitive) setting of the time. there is no battery backup yet but that's simply a button cell soldered onto the one pin that is left floating ;)

 

this chip is in the $3 range. the crystal is less than a dollar.

 

this gives accurate HH:MM:SS time (and also calendar time) for very little cost.

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

 

Updated the title from: Concentric Circular pattern in granite to: Orbicular Granite

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.

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.

Downtown, Palo Alto, California

... 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!).

The Crystek oscillator is a top of the line, ultra low phase noise oscillator

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

Had a weaker shot of a ceiling lamp; washed it through a dozen apps. The pinwheel oscillation.

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 . . . .

‘NODE15 – Forum for Digital Arts’ is gathering designers, creative coders and digital artists for creative explorations of technologies. With the Leitmotif ‘Wrapped in Code – the Future of the Informed Body’, NODE15 is devoted to the negotiation of the body and its fusion with technology. It’s a week long rush with hands-on vvvv workshops, exhibition, symposium, performances and artist talks.

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.
