  1. LPFM does interfere on Congress Considering More Low Power FM Stations · · Score: 2, Informative

    LPFM stations do interfere with signals of larger stations. A local high school station near my house - WPHS - is supposed to broadcast on 89.1FM.

    However WPHS interferes with "large" FM 88.7 CIMX broadcasts in an ~ 2 mile radius from the location of WPHS. When tuned to 88.7 FM CIMX , the static and interference from WPHS makes it impossible to listen to CIMX in the area. The inference is not isolated to 88.7 FM but extends to adjacent channels 88.5 - 89.9 FM and can be clearly heard in this entire spectrum - so clear that you would assume that WPHS was actually broadcasting on every FM channel in this range.

  2. Re:Neat Implications on Wii Hacked To Control Sword-Wielding Robot · · Score: 2, Informative

    Real time mirror maybe not but you could get it to duplicate a motion w/o a pre-programmed path. A robot move usually consists of a X,Y,Z location within the operating envelope, a max speed, and whether the move is joint or linear (linear moves coordinates all axis to move along a straight line, a joint move allows the controller to select the optimum path & axis to reach the point)

    You could in fact translate the Wii output to useful robot coordinates and velocities that are within the normal robot operating envelope & joint speeds. Simulations are routinely used to generate robot programs to reduce teaching time and a Wii translator program would essentially do the same thing. How to get those Wii translated programs into the robot controller and running them would have to be resolved. You may be able to write your entire program using indirect point references and then modify those dynamically.

    BTW - that robot and all recent industrial robots that I am familiar with have 6+ axis of freedom and not 3. Count the servos - there are six.

  3. Cable is over-regulated on The Battle Over AT&T's Fiber Rollout · · Score: 1

    With all the hundreds or thousands of individual franchise agreements its a wonder there is any cometition at all in any one particular city. The fix is a state wide uniform franchise agreement as recently passed (but yet unsigned) in Michigan

    http://www.legislature.mi.gov/documents/2005-2006/ billenrolled/House/pdf/2006-HNB-6456.pdf
    The "Uniform Video Services Local Franchise Act".

    AN ACT to provide for uniform video service local franchises; to promote competition in providing video services in this state; to ensure local control of rights-of-way; to provide for fees payable to local units of government; to provide for local programming; to prescribe the powers and duties of certain state and local agencies and officials; and to provide for penalties. ....

    It sets statewide franchsise fees and rules and removed all the local political bullshit and graff.

  4. The scoop... on UBC Engineers Reach Mileage Of Over 3000 MPG · · Score: 5, Informative

    Almost all designs have drivers lying on their backs. When I was in college, we were the only team to have a head first design with the front axle (w/2x700mm bicycle tires) above the drivers torso, arms in front, and his feet went on either side of the rear drive wheel. Although there is no express rule prohibiting it, the people running the competition thought our design was unsafe (huhh) and forced us to retire the chassis after 2 years.

    Having driven before I can say that they pick the smallest guy on the team (must ballast up to 150lbs I think) and cram him in. No air flow, hot, loud, and no fun - definitely no DVD player. You burn to get you speed up, then coast. You can run as many times as you want and take the best run, you just have to wait for your rotation.

    As mentioned by previous posters, Briggs is a sponsor so teams are requires to use a Briggs&Stratton engine. Most teams only use the case (required), replace the shell bearings with balls, de stroke it and sleeve it to a smaller displacement (we used a Honda piston & rod), make a new head with overhead valves (the Briggs is an L head). During are first years we used a modified stock ignition and aftermarket carb but by my senior year we had a pretty sweet ECU with fuel injection (we re-calibrated a GM ECU). Most drive trains at the time were chains to a pillow block with a centrifugal clutch. The total engine/chassis weighed like 80lbs.

  5. Re:I'm no mechanic, but... on Technology Makes New Cars Too Expensive to Fix · · Score: 1

    CAFE standards are crap. They exist only because politicians dont have the balls to raise gasoline taxes. IF avg fuel economy is going down it's the consumers fault not the mfgrs. They amke a product - dont like it dont buy it. Economics 101 - you cant legislate the supply side. Damn democrats.

  6. Re:Why blame technology? on Technology Makes New Cars Too Expensive to Fix · · Score: 1

    Well you sound like you know what you're talking about - NOT.

    Your fully loaded $17K cavalier with 2% inflation over 6 years is ---- $19.1K not much different than the price your complaining about so much and now includes more features than the original one in 96 (didn't check that date...). Ohh - the MSRP direct from GM site is $10,700-$18,175 so maybe they're cheaper....

    The car does not have a frame so it cant be 20 years old, and although it is referred to as a J body like its predecessor it is in fact a totally different vehicle and none of the manufacturing equipment used to produce it was re-used from the previous model (the exception may be some conveyors).

    Most of what parts are interchangeable? Maybe some driveline components and other misc parts between like model cars - but can I put my 8.1L gas hog from by 2500HD GMC in a Cavalier (that might be fun actually)?

    The fact is that some people have more disposable income and they choose to want a nice car. If you don't like them or think they are too expensive don't but them - don't bitch about basic economics. Even the domestics have cheap strippers for those than want them - hell up to last year you could get get a 4-cyl S-10 pickup for $12K.

  7. Re:Chipping at Privacy on US Congress Committee Talking About Privacy · · Score: 1

    I totally agree. The problem is that the average American is ignorant and doesn't care or cant see past the end of his nose to the long term implications. Most think it has no affect on them.

    You see it on TV during one the spot interviews all the time. The standard answers are

    1) If it helps fight terrorism it's a good idea.
    2) I don't have anything to hide, if it helps fight terrorism it's a good idea.
    3) Yes, I think Arabs should be more scrutinized at the airport, so if it helps fight terrorism it's a good idea.

    It all those "common sense" chips that are the problem. I rejoice every time another part of the Patriot Act is ruled unconstitutional.

    I find it humorous that one of the questions in the US Guide to Naturalization:

    75) Whose rights are guaranteed by the Constitution and the Bill of Rights

    Answer) All people living in the United States

    The answer should be

    US citizens only, and then only if a US Supreme Court rules that the DOJ must give US citizens due process.
