In the special International Railway Congress issue of the Railway Gazette for 1954 English Electric splashed out with their advertising budget taking a series of full colour pages for adverts looking at the company's lineage and products. English Electric had been formed in December 1918 and brought together a number of companies who had been involved in electrical and mechanical engineering along with wartime munitions work. Of the various concerns it was Dick, Kerr of Preston who had been most involved in transport; primarily tramways but also in railways. The following year EE purchased the Siemens Brothers Dynamo Works Limited at Stafford, works that were to become a major centre of EE activity.
Postwar and the early 1920s saw EE, like many other industrial concerns, struggle financially and in 1928 it was necessary to restructure and recapitalise the company to keep it as a going concern. By 1930 it was announced that much of the capital behind the restructuring came from the American Westinghouse businesses. EE now prospered somewhat to become one of the major UK electrical companies alongside GEC and the AEI group. During WW2 EE became involved in aircraft construction and, by acquiring Napier the aero engine company, the post-war aviation business became an important sector. In 1960 this became part of the new British Aircraft Corporation as the sector raionalised under Government pressure.
In terms of railway work, EE made many traction motors and electrification equipment that were used in 1930s schemes for expansion at London Underground and the Southern Railway. The construction of diesel locomotives began in 1936. In post WW2 years EE acquired both the Vulcan Foundry and Robert Stephenson and Hawthorns Ltd in 1955 to strengthen the business. As can be seen from the adverts much of EE's output had been in the form of exports and the UK railway stock shown dated back, some to pre-EE days. In a way the lack of UK materials shows the slow progress that the newly Nationalised British Railways were making in terms of Modernisation and the undertaking's somewhat slow pace in the replacement of steam with diesel and electric traction. In the years after 1954/55 as BR's Modernisation Plan took hold EE did supply many new items of rolling stock to BR.

The Kenwood 4-Channel Power Amplifier model KAC-646X was a pricy (at the time of release in the late 90’s/early 00’s) amplifier for those who were into taking vocals to another level. The maximum power output at 4 Ohm for this amp in the 4-, 3-, and 2-channel configurations are 50Wx4, 50Wx2 + 140Wx1 (bridged), and 140Wx2 (bridged). The frequency response on this amazing piece of hardware spans 10Hz - 45kHz which accentuates the build quality that Kenwood provides. In addition, you have the option of applying an 80Hz low-pass filter or 150Hz high-pass filter to further let you hone in on the frequencies you desire. Even more interesting is the ability for the user to amplify 2 independent signals simultaneously with the slide of the AB/A input selector switch. There are many more goodies that allow for input signal impedance matching and operation mode to best suit your needs! You certainly pay for these variations in complexity and stability with Kenwood!

STORM, world's first electric touring motorcycle, designed by students of TU Eindhoven.
I'm not entirely sure what this is but I happend upon it while looking around in the power lab today. If I were to guess I'd say it is some sort of switching device that uses IGBTs (Insulated Gate Bipolar Transistors).

We recently finished fabricating and characterizing the devices for our EE 143 class at UC Berkeley (Microfabrication Technology). It makes one a bit nervous to hold something so fragile in your hands!
Each one of the chips is around 5mm on a side. The chip layout can be seen here at the EE 143 website. Can you find all the devices? :) My favorite is the designer's initials in the batman figure. You can barely see it in the largest size.
A number of the chips shown in the photo are severely damaged by scratches and defects. I pointed some of them out in the notes.

Parallax Propeller SchmartModule
This board is populated with everything except for the Parallax Propeller Chip, memory and the optional Parallax Crystal. You hand solder these parts using SchmartBoard|ez technology which makes soldering easy and flawless(and some headers which are included). The Propeller chip makes it easy to rapidly develop embedded applications. Its eight processors (cogs) can operate simultaneously, either independently or cooperatively, sharing common resources through a central hub. The developer has full control over how and when each cog is employed; there is no compiler-driven or operating system-driven splitting of tasks among multiple cogs. A shared system clock keeps each cog on the same time reference, allowing for true deterministic timing and synchronization. Two programming languages are available: the easy-to-learn high-level Spin, and Propeller Assembly which can execute at up to 160 MIPS (20 MIPS per cog).
