so these are called Warner electric brakes, designed by the guy who designed magnetic speedometers standard in pre-computer automobiles. clever design, but i think the standard modern setup is in the plans.
here’s the hub off, friction pads inside the hub, and magnetic coil is the ring around the spindle.
closer look at the hub pads,
i assume it works like: give coil juice, it gets torqued by pulling these pads to it and then the doughnut is forced to turn a little bit. that turn then pushes on the pad ring to engage the hub. heres a closeup of the tab that sticks out of the coil ring where it can push on the ring on either side (forward or backward same power).
so yeah, i’m back to the wordpress blog thing, which copies automatic to fbook.
ya ever notice how an iced drink behaves on a hot day? the ice gets smaller sorta steady like, then theres a pause, where the cubes are about 1/3 their starting size, and they don’t change size much for a bit. then, suddenly they’re gone? saw a version floating on the net without any attrib, so this version of the graph is direct from NSIDC, the folks who actually count the icebergs.
and why ? well it seems the ocean warming has warmed right up to the doorstep of the icepack, and the “plugs” in the straights aren’t forming. see the really dark red spots in the bering straight? and like all from Greenland to russia?
don’t worry, Santa has water pontoons on the sled.
too bad for the reindeer tho,
here it comes, first good cold storm of the season, from .mx to .ca.
SuperMoon. harumph. bullies shame the smart, and american schools teach to the lowest common denominator. well, it ain’t common, it’s called “Perigee”, when the Moon is closest to Earth, as opposed to “Apogee” when it’s the furthest. One of these days we’ll rid the earth of the last of the science shamers…
whatever, tide was SUPER LOW, and that is SCIENCE WIN!!!!
sound like someone laughing?
H I H I.
traditional morse code goodbye is “73”.
that is –… …– or dah-dah-di-di-dit di-di-dit-dah-dah.
say it fast.
nobody really knows the meaning, but the usage and rhythm i always think:
“As Above So Below”.
yes, i admit, this is how i “recycled” my engine oil for many many years, usually didn’t bother with the gravel however….
kinda makes ya wonder what’s the big deal about a pipeline? i mean, whats just one more oil leaking greed vein?
ok, these are HP batteries. one is as expected, full of cells.
but the other has these black cells, ive never seen black cells before?
oh wait, those are not cells, those are hollow plastic spacer tubes?
i guess even the big buys cut corners when they can?
would never tell from the outside that 1/3 of the cells are missing inside?
original apple macbook batteries are a study in density packaging, not a spare cubic in there, all pouch cell and fancy TexasInstruments BQ battery chip.
was going thru some dead batteries, and found one non-original that felt suspiciously lighter than any others. you don’t own it till you open it, so,
looks all official on the bottom, CE cert and all that, but, what’s missing inside? how about only 1/3 the space is battery cells?
and what kind of cells are these? look like some sort of tablet battery, really thin, testing one now shows about 2800mah capacity, WAY lower than what the outside says!
yup, even says only 13.87Wh, way less than the 57Wh the outside says!
at least it looks to have a cell balancer, and since it talks to an apple laptop, must have the original TI chip right?
nope, atmel atmega16, might explain the weird responses from the SMC queries….
this is a test, this is only a test, had this been a real blog entry, it would have overflowed the twitter buffer by somewhere around this many characters i thought….
