proxy-posting is a good way to draw membership, but it might be a good practice to delay any proxy-posting for a week or so from upload, to give the uploader a chance to first post here himself, should he be a member. KEvron

say it loud! KEvron

i'm not sure there is such a thing as an official definition; there are only, as far as i know, definitions. they'd've laughed orville and wilbur right outta kitty hawk.... KEvron

a recent thread regarding issues with differentials prompted me to post at youtube a couple of video studies on differentials in clock movements. KEvron

i don't know the model at all, but it sounds like a differential issue to me. make sure the diff's internal gears have some play within the housing. KEvron

then leave the motor behind! KEvron

ah, the dark side. i can only imagine what other nefarious notions dwell within the minds of the otherwise mild mannered wonks at lego, bless their pocket protectors. of course, i appreciate the challenges of the designs found in that book, but i applaud lego's continued stance on the designing of Toys of Mass Destruction (though they have strayed a bit from that philosophy in the last decade). but to harm an innocent lego element, what never did nobody any harm....! KEvron, stick-in-the-mud purist

*gasp!* i'd sooner cut off my own teeth! the few i have left.... KEvron

in his study of the two-body problem, newton refered to effective inertial mass as reduced mass, with regard to one body of mass affecting another: m(reduced) = (m1 x m2)/(m1 + m2) as for the issue of "is it flight or isn't it": by semantics, i suppose D is correct, but i'd just as soon continue to refer to flight, as we commonly understand it, as just that, "flight", withouot any qualifiers ("free flight"). KEvron reversal: no, not even via semantics can it be considered flight, because it never leaves the ground. it moves the position of the arm to which it's attached, but the arm remains fixed to the ground, flightless. propulsion, not flight.

propulsion is not flight. though it has a propellor, a torpedo in the water does not fly by the mechanical advantage of displacement. i'm sorry, D, but i won't agree with you on this one. KEvron

uh, a counter-weight does reduce the effective mass of an object. KEvron

yes, please do. that kind of strident reaction is wholly inappropriate for this forum. KEvron

i wonder how much the instruction TOME for the ucs star destroyer contributed to the overall price? KEvron

yeah, i found the ir info at lego.com. google didn't reveal anything about the rf, but i figured it had the greater range. thanks for the legwork, D. KEvron

since it's come up, does anyone have information on the performance comparison between lego's rf remote and their ir remote, specifically with regard to range limits? and by "anyone", i mean, of course, DLuders.... KEvron

the price you paid is comparable to the average bricklink price, so you got a square deal, and i think you will, indeed, be happy with it, once you get used to its bulky, clumsy design. for my money, rf is the way to go for rc racers. KEvron

i have seen this done before, though i couldn't tell you where. a micro scale train. it had a christmas theme, i think. if i recall correctly, the wheels were fixed, but it worked just fine regardless. KEvron

he who would pun would pick a pocket. mods, can we get a ruling on this?! KEvron

make clocks, not war. personally, i'd like to see some practical applications. things with a scietific aspect. maybe a telescope/microsope, a balance scale, a simple clock even. stuff like that, with an emphasis on the Six Simple Machines. you know.... edumacational. KEvron

in the same manner by which one arrives at carnegie hall, i would expect. build a thing, then re-think it, then build it again. this will develop your chops. i'm a blue-collar schlub with no college education whatsoever. i never let that stop me. KEvron

this thread should be mandatory viewing for driver ed students. "red brick asphalt." oh, the humanity.... KEvron

exasperatingly so, yes. for years, i designed exclusively with the traditional anchor escapement. it wasn't until last year that i tried my hand at something more mechanical, and i'll never go back. the arnfield is infinitely more reliable than any other escapement i've ever employed. i also recommend some form of knife edge suspension for the pendulum instead of an arbor (axle); it'll improve the peformance of the pendulum on a level of magnitude. as for robust, i refer you to youtube user thebellsandwhistles' arnfield (a stunning piece!). he didn't realise that his unique design would incur serious wear; his arnie ran for a few months before the plastic dust, which had accumulated as a result of that wear, finally gummed the works. long story short: it'll run 'til you pack it full of sand! if you've made serious efforts at designing a lego clock, then you should have a pretty good grasp of the physics involved, so i would strongly encourage you to give an arnfield a try. you'll find that tuning the arnfield is quite intuitive, for the most part, though it's not without its frustrations. nothing worthwhile ever is. KEvron

you're really too kind, burf. is there any better hobby than ours? KEvron

does it come with cup holders? (i'm gonna get endless mileage outta that gag!) KEvron

you plan on going internal combustion, tim? KEvron
