On a February winter's day, SSE replacing a transformer, giving me the morning off, no electricity or broadband, my excuse anyway.
Full marks to the guise though, snow, hail, sunshine, that got the lot!

I received an invitation to photograph a controlled barn burn this morning with the men and women of the Clayton Fire Company (Station 45) and Townsend Fire Company (Station 26). What a great group of firefighters! Thanks everyone for making me feel so welcome.

I used to have to pull on chains to control the ceiling fan in my bedroom. Well NO MORE. I have this nice wireless remote here that controls fan speed based on a set temperature. It also controls the lamp, allowing me to dim it to any level.
Also, a great feature is the fan timer -- since often I turn on the fan when I go to bed but in the morning it's off because the room has cooled off. But with the timer it makes sure the fan shuts off after I get off otherwise it would turn back on once my room warms back up during the day.
A good buy from Home Depot!
My Dad (electrician/handyman previous to current RN work), my uncle Bill (party thrower extraordinaire), and I (wee little peon) made this electric set up to set off fireworks at my uncle's July 4th party. This is the plug box half. Just a bunch of 12v dc parallel circuits. Switched by 24 house switches in a different box about 60ft of cable away. Each plug gets an extension cord plugged in. We modified the extension cords by replacing the female end with two alligator clips. Between the clips we attached little resistors as improvised electronic matches. On the night of the party we tapped the resistors to their fuses with a bit of electrical tape, flipped the switches on time, set to a music mix, and watched the fireworks fly.
My uncle Bill came up with the initial circuit design and my Dad and I volunteered to put it together. My Dad put together the switch box while my sister and I worked on the music mix. As I'm far from an electrician, it took me about an hour to wire all this in and another hour to make the plugbox enclosure.
The overall project took more time than planned as we had a couple of miss-starts when we tried to use a bunch of untinned tiny momentary switches, ended up giving up on them as they were taking to long. We also started making an enclosure for the switches out of plexiglass, but once again that was taking forever and was scrapped as time was running out. Overall, about 10 hours worth of work went into it. Though now that the overall design is set, I'd say we could make another one in just a couple of hours.
It was a very fun little project and worked out well.

The British Railways BR Standard Class 9F 2-10-0 is a class of steam locomotive designed for British Railways by Robert Riddles. The Class 9F was the last in a series of standardised locomotive classes designed for British Railways during the 1950s, and was intended for use on fast, heavy freight trains over long distances. It was one of the most powerful steam locomotive types ever constructed in Britain, and successfully performed its intended duties. The class earned a nickname of 'Spaceships'.
At various times during the 1950s, the 9Fs worked passenger trains with great success, indicating the versatility of the design, sometime considered to represent the ultimate in British steam development. Several variants were constructed for experimentation purpose in an effort to reduce costs and maintenance, although these met with varying degrees of success.
The total number built was 251, production being shared between Swindon (53) and Crewe Works (198). The last of the class, 92220 Evening Star, was the final steam locomotive to be built by British Railways, in 1960. Withdrawals began in 1964, with the final locomotives removed from service in 1968. Several examples have survived into the preservation era in varying states of repair, including Evening Star.
Transillumination shows ventilation through the chassis. They allow passive ventilation and when the fans are activated, serve as added flow through to cool the interiors. Thus, the whole interior assembly is open to cooling.
The controls of the aerotone certainly gave you an idea of how powerful it was, especially with the likes of a compressor control!

U-434 - soviet name originally B-515 - is a soviet submarine of the Tango class built in 1972. It is now open to the public as a museum ship in Hamburg close to the fish market.
18 month year old, Ranu, plays in the forecourt of the village. Her father drives a big truck up and down the main highway that connects Kathmandu and Pokhara. In my waking life at the village he was gone by the time I woke up, and came back by the time I went to bed. These sacrifices made reminds me of my own childhood, and how similar the scenario it was in my own household, years ago, and so many miles away.
