Woke up this morning to a fresh rumor about Nintendo releasing two new Switch models later this year. One would have a bit more advanced features than the current iteration, while the other would be more budget-friendly and remove some features.
The first’s upgraded feature set would...

Mechanically switched moving coil movement (rare)
This is a mechanically switched model. The pendulum moves back and forth within a curve bar inside which contains a permanent magnet. The interaction of the magnetic field between the coil and the magnet keeps the pendulum in motion thus keeping the clock running. What set this apart from most of the electro-mechanical design is that this guy is a true moving-coil type oppose to the commonly encountered moving magnet type. The moving-coil type is a more complex in design of the two.
7 Jan 2018, Just dig out this clock over the weekend to have a look at it after years of storing away in the corner of the house.(after cold storage it for for than a decade)
To my amazement. I discover that it has an interesting moving coil design (a very rare mechanism in clock design due to its complexity) instead of the usual moving magnet type. Moving coil function is much more difficult to achieve and manufacture in term of triggering the circuit via a coil literally in motion. This action provides the impulse keeping the pendulum in a constant motion which in turn keep the clock in operation.
From its appearance, it looks just like an ordinary swinging pendulum clock. But there’s where the similarity ends. A closer look reveals a very ingenious construction center round the pendulum rod which the coil is attached.
The 1.5VDC +ve potential provide by one of the 2 batteries (the other battery is to power the motor which runs the chime) is connected to the suspension spring support assembly via a bolt which is completely isolated from the body where the –ve potential is terminated.
The suspension spring would then have a direct contact to the +ve rail once mounted onto the support. As the metal pendulum assembly is kept in position by the suspension spring, the entire rod is at a +ve potential. A short length of wire soldered onto the rod at the opposite end served to feed one end of the coil, which is also mounted on the rod.
The –ve potential is transmitted to the other end of the coil via a long wire running down from a contact point located in between 2 forks assembly mounted on the main body. As the pendulum swings, it rocks the fork assembly along and simultaneously making and breaking the contact with the main body which at –ve potential. This action switches on and off the coil at a specific moment creating the magnetic force needed to interact with that provided by the permanent magnet mounted inside the stationary curve rod.
This interaction of the magnetic fields keeps the pendulum in motion. The forks assembly mentioned earlier works together with it, operates a pawl which advance the gears assembly with each successive swing of the pendulum keeping the time train in operation.
The clock is designed to strikes out the number of hours on a single steel rod. It is equipped with a conventional rack and snail mechanism. An electrical contact is made every time the mechanism operates which closes the connection to a small electrical motor which then operates the strike train.
The major challenge of the moving coil design is to bring the electrical supply to the coil which is in motion.
Due to its complexities, it did not take long to fall out of favor to the simpler moving magnet design, which the position of the coil is fixed and the permanent magnet is free to move with the pendulum while mounted on it.
The major drawback of these clocks is still the unreliable physical electrical contacts which used to operate the circuit. Before long, most if not all of these clocks will fail due to poor or defective contacts.
The solution, the transistor. At its time, this amazing little invention takes the world by storm. It revolutionize the electronic industries making the once impossible possible.
The clock industries too jump on the band wagon and adopt this little baby replacing all of its electrical contacts with this state of the art semiconductor device. It works wonder.
However, it did not take long for all these electro-mechanical clocks to go extinct with the emergence of the quartz technology. They are many times more accurate, compact, long lasting, reliable and cheaper than its predecessor.
Though, the electromechanical clock is short lived and most don’t even know of its existence it occupies a very interesting portion in the ladder of clock evolution.
After some servicing, this clock is back in operation.
Only Time will tell and every clock tells a story....
The problem with clock is, once you got two they start to multiply..
It all started when I acquired my first clock a 1960's jap 7-day wall clock from a colleague of mine by the name of Wong Mun Lai, a clock collector

It was a non-working clock which I wanted to hang up for display. After a while, I felt something amiss. A clock is not a clock if it does'nt work! So I took it apart and do some fixing, to my surprise I managed to get it ticking again ! I was totally fascinated From there I got my second, third and so on....
My favourite has to be the 400 day clock
Amazing time piece and fun to repair Next in line is those of the electromechanical design type
I love the working principles
At the time of writing, my collection is still growing....but has grind to a halt as my interest is now focus on nature photography
Two turnouts are in place on this module. To control the points two push/pull rods are used. The are covered with a small red wooden bead to enhance the grip.
I decided to have a go at some creative light painting this weekend. My girlfriend Jemma was kind enough to participate and model for the images.
This is a 30 second exposure, I used an external flash with a red gel to capture Jemma, and I then placed a black paper in front of the lens so that it wouldnt capture any more of Jemma, this in turn stopped the photo being over exposed.
I noticed this greenish swicther several weeks ago when I drove by the UP lathrop intermodal facility from a distance. I came back today and caught it with the camera - but I could not get too close to get a better angle. It seems that UP leased this unit along with RLIX 164 at this facility.

Class: MRS-1 (Military Road Switcher Model 1)
Bluegrass Scenic Rwy., New Haven, KY
Built in 1953 for the military, MRS-1 class diesel locomotives were built for the specific purpose of being a motive power source to be used on the rail networks of foreign countries. To do this these locomotives are equipped with special telescoping axles which allow the engine to operate on any track between 3 feet and 5 feet between the rails.
To control the polarity of the frog a DPDT-switch is used. Additional the spring within the DPDT-switch keeps the points in place. The DPDT-switch is moved bij a screwterminal where on one side the screw is removed to accomodate the top of the switch.
Both sidewalls of the module have a hole. Recessed behind it is a second piece of wood. The control rod is feed through the hole.

Another digital study for a technical camera assignment. The goal here is to show a glimmering object. For the buffs: I used a softbox on the knife and a straight reflector light to catch the knuckles of the glove. I later moved the reflector light to the left and turned the softbox away from the background. I also switched models. This hand belongs to my cousin Lieven but the final photo was taken with another fellow student: Lesley. I will show her later holding the knife.
The Southern Ontario Locomotive Restoration Society apparently owns most of the rolling stock that was stored at the Michigan Central Shops building (ca 1913) in which you see #9 stored here. They share this building with the Elgin County Railway Museum. (See the notice they have posted in the comments below.)

Onto box at a high 45, normal portrait edits(teeth whiten, skin soften, spot corrector) put the pictures together in photo shop. We had a couple last minute fixes and had to switch models.
The actual points are moved using a screw terminal with a piano wire embedded (see the schematic). The rod is bended like a Z and kept in place using two brass eyelets. The angles are used to control the side movement of the main control rod.
Even a turnout on a angle can be controlled using the methode as long as the angle doesn't get to steep.

Resumo:
Based upon the authors' experience in designing power electronics courses, SPICE for Power Electronics and Electric Power, Second Edition integrates a SPICE simulator with a power electronics course at a junior or senior level. This volume assumes no prior knowledge of SPICE and introduces the applications of various SPICE commands through numerous examples of power electronic circuits. The authors emphasize the techniques for power conversions and for quality output waveforms, rather than accurate modeling of power semiconductor devices. This text enables students to compare the results with those that are obtained in a classroom environment via simple switch models or devices. Not only a supplement to any standard textbook on power electronics and power systems, this volume can also be used as a textbook on SPICE. It suggests laboratory experiments and design problems, and presents complete laboratory guidelines for each experiment. This book can also be used as a laboratory manual for power electronics, with its design problems serving as assignments for a design-oriented simulation laboratory.

To actuate the point you need a stif wire (piano wire). It is folded as a J and added to a screw terminal which is placed on the actuator rod.

The dashboard was in decent shape & the rest of the interior trim pretty good too. The seats had been recovered recently however I had decided to fit the seats from an MGF or MX5 and replace the dash with an earlier flick switch model. The dash would also be colour coded to match the body. The very nice Moto-lita steering wheel will be reused.

I spent the day either preparing for the clinic that I was going to present or attending other clinics at the convention. I almost forgot to get a photo today, so I took a couple at the last clinic that I attended. Here, the clinician is showing us how to make some quick upgrades to track switches so they work more reliably.

Thu Tran, Santa Clara CA - Systems Engineer- Sr.
Presenter: Juan Fontanes/Shin Takahashi
Applicable Criteria: Innovation and Customer Relationship
Reason Selected: Thu contributed his technical expertise to an effort to integrate DELL switches with NEC SDN Controllers to provide joint SDN solutions. In order to realize this strategic alliance, interoperability and quality issues had to be resolved. Thu, working with the DELL and NEC Japan engineering teams, provided great technical suggestions and resolved several technical issues that resulted in a viable solutions. He personally tested 12 DELL switch models and worked through several nights with both DELL and NEC engineering teams to complete development on schedule.
As a result, DELL won its first joint customer sale (Cornell University). Thu earned the respect and trust of DELL, further strengthening our overall relationship with the customer. This has also led to NECAM winning our first SDN+UC solution contract through our sales channel, which his contributions were valued throughout the design proposal phase.
