Rectifier and dual triode vacuum tubes on the job since 1963. The glowing filaments heat a cathode sleeve that boils off electrons that are then captured by a charged plate. For the rectifier, they can only go in one direction, and AC is converted to DC. For the dual triode, control grids fashioned like a finely wound fence are interposed whereby a small change on the grids cause a large change on the plates, and amplification is achieved.
Zoom to explore.
Canon FD 100mm f/4 macro, taken at f/11, long exposure on tripod.
Inspired by beetles and fabricated by a robot, this striking garden pavilion kicks off the Engineering Season.
V&A.
A spindle, longer than the stock spindle (which can't handle some 3d filament reels, not long enough...) to hold reels of filament for a Wanhao Duplicator 6, or the re-labelled Monoprice Ultimate (what I have...) Seen on an MSI laptop computer (the only place I had free with a contrasting background...) with LED's under the keys. 3D printed on the printer it will be used on. Taken in my home "studio" in Albany, CA by a Nikon D610 at ISO 400 with a Nikkor 50mm ƒ 1.4 AF-D lens. Exposure is 1/50 sec @ ƒ 3.5.
Printed with 1 mm walls (up from the stock .7mm…) and a 25% infill, (up from 20%…) from PLA. Printed with the flanged end down, with supports. (left a major clean-up job, too...)
It works well, but needs either to be roughened a bit, or a layer of blue painter's tape on the top for some extra friction, otherwise you'll get a bad tangle as when the printhead moves back it backs up the filament, and that can cause it to jump over the side of the reel...

There is explicit photography in the magazine. We don't generally put that on Flickr.
Hey there, little light bulb.
Look beneath your sunny glow.
There lie a dozen empty flower pots
filled with seeds waiting to grow
A macro look at the stem part of the stamen called the filaments. At the top of these stems are the anthers which produce the pollen.
I like the green color of these filaments, as well as the fuchsia of the petals...

Enormous Solar Prominence captured by STEREO Spacecraft
The twin STEREO spacecraft (called “Behind” and “Ahead” denoting their relative positions in space), now almost 120 degrees apart, captured this large and dramatic prominence eruption over about a 30-hour period between Sept. 26-27, 2009. Prominences, called filaments when they are viewed against the surface of the Sun, are clouds of cooler gas suspended above the Sun’s surface by magnetic forces. This erupting prominence was large enough that both spacecraft were able to observe it for hours on end, one of the first times that has occurred.
From the Behind perspective (on left) the long filament, darker than the Sun’s surface, can be seen rising up and then breaking away, spreading out above most of the Sun’s surface. As seen from the Ahead spacecraft (right), the filament is seen in profile and is therefore called a prominence. The very large cloud lifts up, breaks away, and heads out into space. This is one of the most spectacular eruptive prominences STEREO has observed.
