    Get the helmet painted... in fact... go for the whole getup (attached) and then during your skydive while you are filming a group dryly chant to yourself, "Stay on target. Stay on target."

    When Motorola started their iDen sector (which designed all the PTT Nextel phones and accompanying infrastructure) it was targeted at small businesses that wanted two-way radio service across local areas, but couldn't afford their own network like police/fire departments had. This was a great way for any onsite work, delivery operations, etc. to stay in comms, and there are tons of companies like this. Sadly, this is yet another case where marketing lost track of "The Whole Point" (tm) and now we have people carrying on phone-call lenth conversations hundreds of miles from each other with a "bla-deep bla-doop" between every thing they say. Which... just... I... ...I'm holding my head with both hands right now so my brains don't come out my ears.

    A typical bluetooth headset emits around 2-3mW of RF power. A typical GSM cellphone emits between 200-300mW of RF power. A typical microwave oven emits around 800,000-1,200,000mW of RF power.

    Bryan Harrell has a few behind the scenes photos of this event in one of his galleries.

    A two bedroom/two bathroom condo of about 1200 sq ft (110 sq m) is going for $500,000 or more in Redondo Beach, CA. Which is why I'm looking in neighboring areas.

    Are you sure about this? I'm a little rusty on my thermodynamics, but IIRC maintaining a temperature gradient always costs more energy than getting there. Obviously other considerations need to be taken into account (pets in the house, freezing pipes, etc.) but I would think the outside temperature is the limit for how low you can go and continue to increase savings. That said, I just live in southern California... my climate control involves opening the window.

    Freefly suits

    champu replied to jtval's topic in The Bonfire

    shameless liquid sky plug. similar "photo examples plus pdf orderform with diagrams" set up that most of the other manufacturers have... but since you're looking, they do make really nice suits.

    Anyone with a legstrap PC should seriously consider revising their gear choices before partaking in tubes, magic carpet rides, hybrids, or even freeflying really.

    Fresh out of college, I included on my resume that I was the president of my university's skydiving club as an example of leadership experience. During the "experience" interview (step 2 of 3) I talked about how I got started, what made me decide to be the president, what kind of things it involved, challenges, etc. During the other interviews, the people appropriately ignored that I was a skydiver. In college I also liked playing video games... and drinking... but I didn't bring these up because they're irrelevant. While Halo and Beer-Pong often got very competitive (and I excelled at both) this was not the type of leadership they were talking about. The next time I have to update my resume I'll likely take the skydiving club off as it'll have been a while and they'll want more recent examples. On a side note, did I miss something? what was wrong with calling it a "resume"? I mean... "curriculum vitae"? "the course of my life"? That sounds a little overly dramatic to me.

    You'll probably be hard-pressed to find a lighter digital camera than the RebelXT that can compete with its quality. It's actually lighter than a lot of 35mm bodies out there. I have an FF2 with a pc105/diamond0.3x and a rebelXT/sigma15mm top mounted with a stroboframe, and the whole thing weighs about 5.5lbs.

    coarse rounding of numbers that small, particularly in finance, can be dangerous.

    I actually kept packing right in front of your tent because I was curious as to what you'd tell the next person that came up asking for a napkin.

    no no no... Two biscuits, two scrambled eggs, two sausage patties, melted cheese, and hashbrowns. Form a pile and cover it in gravy.

    Nah, the earth doesn't get its rotation from its conveyor belt, the friction there is negligible. This is obviously a tidal problem. /edit: agh! it's vs. its

    The way this thread is going, I'd just like to have a definitive QUESTION. It's as if someone walked into the thread and asked what time it was. And I answer "it's 6pm" and then someone else jumps in and says, "no it's not, it's Wednesday." and I ask the second person what they're talking about, and they say, "well the original poster didn't really phase the question right, they should have asked what day of the week it is, and it's Wednesday." Meanwhile five other people are going on about, "leap years happen every four years, but that it's all a trick question because 2000 wasn't a leap year. I can't believe how many idiots don't know that."

    Yes, and once the post has been edited, the seal of comedy freshness has been broken. Reject if safety button is up.

    I'm sorry, I answered the question as it was asked in this thread as opposed to changing the question to what I thought the person was trying to ask, and then answering it. How silly of me. This is not a stable control system, it doesn't matter WHAT you put on this conveyor, I don't care if it's a skateboard with a desk fan on it, an airplane driven by the thrust of it's engines, or a fat guy on roller skates that the almighty himself fucking miracles forward, as soon as whatever it is tries to move, the conveyor will accelerate out of control. /edited to add: This is, indeed, a COMPLETELY different question, and not even really an interesting one as far as I'm concerned.

    This is exactly my point. If the speed of the wheels even got the slightest bit of a leg up on the speed of the conveyor you could take off. But that's not what the problem said, the problem said the conveyor would match the speed of the wheels exactly at any given moment. The video that got posted of the skateboard is nonsense, he lets the thing go and then starts pulling on the paper after it's already moving. That completely circumvents the problem. I have one final thing to say, if you take anything away from any of my posts here, take away this: This isn't even a problem of propulsion/aerodynamics. It's a problem in that the control system to keep the conveyor running at the exact same speed as the wheels is NOT STABLE. The INSTANT the wheels even attempt to move along the ground, the conveyor will accelerate out of control blowing up the landing gear before the plane goes anywhere.

    Hey, he still had his Fastrax jumpsuit on. I give Mel a hard time when she wears one of her old Adrenaline jumpsuits too.
  21. champu
    Well let's see... black suit/blue grippers = Eric Gin (Fastrax) who organized the jump... and... the others are going to have to speak up if they post here it was taken Saturday morning if that helps anyone.
  22. champu
    what. in the fuck. are you talking about?
  23. champu
    I shall contribute one random photo from eloy to this thread
  24. champu
    Yes, but that's only true if you omit 80% of my post as you have.

    Sure it does, and here's the problem: 1 - can't generate lift without forward airspeed 2 - can't generate forward airspeed without forward groundspeed (because there's no wind) 3 - can't generate forward groundspeed without the wheels rolling (because you're resting the entire weight of the plane on the ground) 4 - if wheels roll, belt fights back 5 - can't beat the belt unless you beat friction 6 - can't beat friction unless you generate lift 7 - see 1 As they say, "You can't get there from here." Physical experiments aren't going to demonstrate this properly because a belt that can instantaniously match the speed of a wheel rolling along it is a non-causal system, and is not physically realizable. Any lag whatsoever in the feedback loop between the sensor that's measuring wheel speed and the motor control that's driving the conveyor will allow the plane to take off. But that's not what the original question is asking.
