so, I leave work to go home. Its blowing a gale and chucking it down. I've gone not more than 10 steps before my poor trusty brolly is blown inside out and breaks :-( I finally make it to the bus stop and look like a drowned rat. While driving home I remember I've no milk, so pop into supermarket to pick up a pint (getting blown to the Emerald City on the way!)... finally get home, switch on the light and 'POP' goes my favourite lamp lightbulb....guess what I don't have indoors right now!!! (some days are sent to 'try' us!!)

Jesús Rafael Soto (1923–2005)
Penetrable de Chicago
1971
Plastic filaments and metal hanging hardware
"Renowned abstract artist Jesús Rafael Soto was a pioneer—and ultimately lifelong practitioner—of the Op and kinetic art movements, which prioritized both optical illusion and physical dynamism. After training in Caracas, Soto moved to Paris in 1950, where he participated in the seminal 1955 group exhibition Le Mouvement at Galerie Denise René, considered a crucial launching point for postwar experimentation with interactivity and perceptual experience. Believing that perception involves the entire body and not just the mind, Soto and his peers sought to revise the fundaments of how an audience engages with art.
In 1967 Soto created his first so-called penetrable, a kind of luminous environmental sculpture that not only invites but in fact compels audience participation. One of only about 30 ever produced by the artist, this iconic installation is on display for the first time since 1986; an early example of Soto's signature environments, Penetrable de Chicago presents thousands of transparent filaments hanging from the ceiling in a rectangular formation. Visitors are thus invited to enter an immersive field of synthetic tubes that shimmer and shift in response to every moment. 'We are in the world like fish in water,' Soto once explained. In keeping with such a metaphor, his multisensory penetrables render our passage through space fully palpable." (exhibit text)
Switching on the uplighter when I got in from work, I was met with a pop from the bulb. It gave me a subject for my POTD and one for this week's challenge of "high key"
Daily Shoot: 2010/11/04: Today, make a photo that emphasizes or even exaggerates brightness in a scene. #ds354
Yes, new tool for me. I'm new to this, so a bit of youtube and try/error is going to take a place...but it will be fun for sure
Thank you for taking the time to comment, award and/or critique my work, I truly appreciate each and everyone!
Thank you and I hope you enjoy your day :-)

Going to remove the center E and convert to a C core, then use it to wind a filament transformer for the electron microscope project.
The core needs to be large physically because the filament will be placed at an extremely high potential. In order to prevent arcing to the core, the secondary must be very well insulated and possibly even immersed in oil.
Polypropylene filament fiber filter cloth
PP filtering fabrices,which made of polypropylene fiber (PP), can be divided into PP staple fabrics, PP long thread fabrics, and PP monofilament fabrics. These products possess the properties of acid-resistance, alkali-resistance, small specific gravity, the melting point 142 146degree, and normal working temperature maximum 90 degree. They are mainly used in the precision chemical, dye chemical, sugar, pharmaceutical, alumina industrial, for the equipments of frame press filter, belt filter, blend belt filter, disc filter, drum filter etc. The filtering precision can reach less than 1 micron.
Polypropylene filter cloth can be divided into:
PP staple fiber filter cloth,
PP multifilament (long thread)filter cloth ,
PP monofilament filter cloth ,
Main Applications :Separation in solid and liquid to equip with filter press ,conveyor belts filtration Machine ,Filter Leaf ,Horizontal Rotating Pan Filter ,Vacuum filter ,in Chemical industry ,Fertilizer industry ,Sugar making ,food and beverage ,metallurgy ,Building ,Waste water dealing
Representative products :
Thinner filter cloth: 521, 522, 4212, 750A 6030
Thicker and with higher density : 750 B (series),750 AB7842,2402,5422,5514,6320,7640,8628,1384,6433,2436,534

This is what the finished spooler / filament guide looks like. I am probably going to scrap it. It pulls filament fine and haven't had a failed print yet, but I don't like the angle it pulls the filament down at. It is basically going 90 degrees out from the bearings straight down into the extruder. The plastic is visibly discolored by this sharp angle. So I have two options, print a filament guide FOR my filament guide, or move the spool some where else.
