When I started my career with IBM, one of my co-workers was a very interesting engineer, Marvin K. He was extremely intelligent and curious about many things, including astronomy, science, electronics and photography.
About a year after his death in 2004, his wife called me and said that she had a ham radio that he had built as a teenager and she thought I might like to have it. After I brought it home, I noticed that curled inside of the large copper coil, were several sheets of hand-written notes that described a lot about the construction and early use of this very basic radio transmitter. Typical of Marvin, the note was very detailed and contained a great deal of information about the radio. Here is his narrative....
"This is the short-wave amateur radio transmitter I built when I was age 13 in 1931-1932 in Sac City, Iowa. I operated under the call letters of W9AZA issued for the 80 meter CW band of 3.5 to 3.9 kilocycles per second (now called Kilo Hertz, or KHz, continuous wave, where the transmitter is keyed on and off with a telegraph-type key, using International Morse Code, NO voice operation)
This transmitter is a self-excited, push-pull oscillator, using two type ’45 tubes, where a heavy radio frequency current is generated, which oscillated back and forth at the resonant frequency of a tuned circuit consisting to two things: the large copper coil and the main tuning capacitor (or ‘condenser’). Energy is electromagnetically coupled to the two smaller copper coils which are connected to another tuning capacitor and the antenna system. This provides another resonant circuit which is tuned to the same radio frequency as the oscillator. Energy is then radiated from the antenna system…which was a zeppelin-type antenna with a 132 foot flat top, end fed with two parallel wires spaced 8 inches apart, one connected to one end of the 132’ antenna, the other one dead ended there..(not connected).
A separate power supply provided power to this transmitter. It consisted of a 115-volt AC power transformer, one type ’80 rectifier tube, two 8mfd, 450 volt filter capacitors, a filter choke and bleeder resistor. The transformer also supplied 5 volts AC for the ’80 tube filaments, 2 ½ volts AC for the ’45 tube filaments and 500 to 600 volts AC, center-tapped, for the nominally 250 to 300 volts DC for the transmitter tube plates. Plate power input to the transmitter oscillator circuit was maybe 20 or 30 watts, maximum. (I couldn’t afford voltmeters or ammeters which would have told me more...!) My radius of operation was Iowa and the adjacent states – seldom further.
My short-wave receiver was initially a 1 tube regenerative receiver I built and later a Super Wasp receiver, that my neighbor across the street had built and had replaced with a more up-to-date factory-built SW receiver. The Pilot Super-Wasp required a 6-volt car-battery for the tube filaments and a B- battery eliminator (connected to the 115 volts DC house current) for the 45, 90 and 180 volts DC the receiver used. It had plug-in coils to cover the 20, 40 80 and 160 meter amateur bands, as well as the broadcast band. It was regenerative also.
I operated mainly from 1932 thru 1940. The license had to be renewed, with proof of use, every 3 years or so. I finally let it run out….should have kept it active. My license was W9AZA, was a re-issue and came out when the W9K ---‘s (a very early call)...were coming out. My neighbor got W9KDL as the same time I got mine. He helped me, and we practiced code together via a telegraph line he installed between his house, mine and another 1 block away and one more a mile away..!
The plastic cover over the transmitter is not part of the original, but is just to keep the dust off. The cover, from an IBM type 650 scientific computer magnetic drum (circa 1955-1960) just happened to be the right size…!"

Mamiya Super 23, Fujichrome RDP 100.
Offered in the US from model year 1997 to 2001, the Catera was a badge-engineered Opel Omega made in Rüsselsheim, Germany.
The advertisements for it featured supermodel Cindy Crawford speaking to an animated duck-like character anmed 'Ziggy', who lasted maybe 2 years.
It wasn't derided as much as GM's earlier, badge-engineered Cadillac Cimarron was, a car that was easily recognized that it had the same body as the economy Chevrolet Cavalier except with Caddy end caps. But the Catera wasn't a great seller, either, finishing its run of 5 years as a single-run model.
The one depicted has apparently survived and looks to be in very good condition.

THE ENGINEER
I was in the backyard taking a Polaroid of the pool tile when the portrait lens viewfinder attachment for my 195 fell off and sunk to the bottom of the deep end of the pool. My Dad fished it out with the skimmer and after I dried it off, I tried to take a photo of him but couldn't focus at all with the rangefinder. The little glass window on the attachment was totally fogged over with condensation. The 195 can be hard enough to focus in bright light, but here I was in the dim light of twilight with a film of fog over the rangefinder. I took a closer look at the attachment and figured out that there were teeny, tiny screws that held it together and that it could be opened up and really cleaned. My Dad, the lifetime engineer and Mr. Fix It took it upon himself to do the repair and cleaning for me. Now that he's had both his cataracts removed in the last year, I think he can actually see better than me! Once he got the attachment open he told me, "You clean glass with alcohol. I learned that when I worked at a lab at Northrop." I don't really know anything about my Dad's time at Northrop, so I asked him what kind of lab he worked in and he told me that he inspected parts for guided missiles. From as long as I can remember - from early childhood until college graduation - the only company my Dad worked for was Hughes Helicopters (as in Howard Hughes). He was a Quality Control engineer and under his watch there were never any helicopter accidents due to parts failure. Unlike most companies that want to get rid of their older workers, Hughes (then taken over by Boeing) begged my Dad to stay on with the job when he retired at the age of 70. Having worked full-time since he was 18 and with me finally out of college, my Dad had enough of working and retired despite the bonuses dangled before him. Anyway, back to the present - after a few swabs with alcohol and dealing with the tiniest screws known to man - my Dad got the viewfinder attachment clean and clear again, in fact I think it was actually cleaner than when I started. So dropping it in the pool turned out to be a happy accident indeed!

31311 stands wrong line with a ballast train at Barnsley on very dull 5th June 1983. The two nearest lines served a parcels depot which had closed a couple of years previously. The shunting was usually in charge of a DMU that dropped off a a parcels van on the 18.00 from Sheffield to Barnsley if I recall correctly.
The line nearest also served the good shed on the left by means of a head shunt behind the photographer.

GB Railfreight Class 66, 66744 "Crossrail" makes it way out of weekend possession as it passes steadily through Winsford to form 6G48 10:04 Crewe Coal Yard to Bescot Up Engineers Sidings.
As this stretch was still within the possession, it gave rise to the somewhat unusual sight of the train (legally!) passing signal WD49 at danger.
Circa 1977. Here's fellow Engineering student Bill G. His left 'arm' is a prop in the shape of a large pencil. Bill was a staff member of the 49er Engineer, the Engineering school's student-produced magazine of which I was also on the masthead. It was published monthly during the Fall and Spring semesters, with technical articles written by staff and other students.
Why the pencil? I forget who exactly brought it to the magazine office. It was probably once part of a store display somewhere but it was sitting in the magazine office for a period of time. It was then decided to use it for individual staff photos as a common theme within each. This is one of those photos. The pencil was a fitting symbol for writing, and writing was what we did for the magazine.
The photo was taken on the west side of the building designated then as 'E3.'

The Erewash Canal outside Sandiacre, in Derbyshire.
The canal was created following an act of parliament in 1777 with John Varley appointed as engineer and John and James Pinkerton the main contractors, it was completed in 1779 at a cost of £21,000 (£2,252,740 in modern money). It was a commercial success from the start mainly used to transport coal.
The canal's success kept it going far longer than many of its contemporaries in the face of competition from the railways. When the Grand Union Canal Company took over the running of the Erewash in 1932 it was still a going concern. The canal was nationalised in 1947. By this time the closure of feeder canals resulted in a loss of trade and competition from other forms of transport was making itself felt and the last commercial narrowboat delivered its cargo in 1952. In 1962 the British Transport Commission closed the top section of canal. However, it was kept in water to supply the lower half of the canal and it remained navigable.
In 1968 the Erewash Canal Preservation & Development Association (ECP&DA) was formed in response to a threat by the British Waterways Board to close the canal. One of the ECP&DA's achievements was the re-opening of the Great Northern Basin at Langley Mill. This canal basin was the point at which the Cromford, Erewash and Nottingham Canals met. The Langley Mill Boat Company formed in 1974 and based at the Great Northern Basin has cleared and put back into water a short section of the Cromford Canal connected to the basin.
Today the Erewash Canal is fully open and is actively used by pleasure cruisers. The towpath, which follows the eastern bank, carries Route 67 of the National Cycle Network between the Lawrence Street access and Stanton Lock where the cycle route diverges to follow the Nutbrook Valley. The canal is also regularly restocked with fish for anglers, and along the eastern tow path dozens of anglers are often seen.
As a young boy I fell in love with the 611 and now as a grown man I have the opportunity to enjoy running the locomotive.
This big steam engine just stopped for a while in Olten ..... so i share another memory with my flickr friends ..
my granddad was a proud steam locomotive engineer - wen i was a little boy - he told me often :
Ueli - when you grow older - you must
be a Lokomotivführer or a teacher !
So i kept a deep affection to the railroad
all those years - and was a teacher for about 40 years !
Railroad days
Jan would climb up so high on the foul screen
Down below I would yell to watch out
When we'd play ? was always the winner
He was brave never listened to me shout
Afternoons playin' ball by the old wall
Hidin' out and of course be the star
Kept my records in old looseleaf notebooks
And today I think I still know where they are
Oh, Railroad days
Railroad days
Railroad days
When I was young, in my prime
On my way
When the rain never got in my way
oh in my younger railroad days
Some nights, Drifters playin' on the hi-fi
Talkin' 'bout girls, or preposterous lies
Laughin hard, watchin' Soupy at eleven
Skonkin' down, one of Mom's lemon pies
Ten o'clock, bringin' groceries from the market
Singin songs, to the darkness of the night
Even sang the parts the instruments were playing
Life was freer, dreams were really quite all right
Oh, Railroad days
Railroad days
Railroad days
When the sun seemed to smile on it's way
When the darkness was easier to play yeah
oh in my younger railroad days
Yesterday, I heard they shut the trains down
The ones than ran, by the field where I would play
Said the folks want new and faster transportation
It's just like me, I'll be obsolete one day
Oh, Railroad days
Railroad days
Railroad days
When I was young, in my prime
On my way
When the rain never got in my way
oh in my younger railroad days

It was nice and cloudy yesterday, took Heliot out for some photos. He is wearing the Volks SD17 Steampunk set from the Kyoto 9 Dolpa. The colors and textures of the outfit are beautiful.
Engineers, project managers, and construction workers meet at the construction site to discuss the progress of the expansion. The project is on schedule thanks to the efforts of hundreds of workers. Commissioning of the new powerhouse will take place in August 2014, substantial completion in December 2014, and will be fully online in February 2015.
Tangerize Engineer-class soldiers are usually those who are the most proficient with the more technological and sometimes explosive aspects of being a soldier. Engineers are often tasked with setting up security cameras, automated turrets and explosive traps. Engineer units were responsible for many MAF troop deaths in several important sieges during The War, seeing as the Engineers were also tasked with taking out enemy transports and aerial attack units, as well as setting up turrets and mines.
