  1. Re:Neat... any open source implementations? on (Short-, Medium-, Long)wave Radio Meets Digital Stereo · · Score: 1

    You may check the following links:
    Software impementation under GPL
    Receiver modifications to receive DRM broadcasts
    Hope this helps a little

  2. Re:Two stroke? on Aqwon, the First Hydrogen Scooter · · Score: 1

    Ondly o few facts some of my friends showed me

    1) The Power generated by a two stroke engine is (in theory) twice the power of a 4 stroke engine. But you have ondly half the frition and with the right materials less heat-loss thru the cylinder-surface.
    2) The exhaust of an Two stroke engine is normaly so bad because of several reasons:
    a) Some fuel excapes unburned in clasical two stroke engines because e mixture of air and fuel is used to move out the exhaust. this is not true for direct-injection engines (like disel engines, and maybe this on)
    b) Oil is mixed with the fuel. but this is not nececery for every two stroke engine design

  3. Re:pirating electricity? on Wireless Electricity Set to Power Village · · Score: 2, Informative

    This has been done in Hof / Bavaria / Germany
    Some people used the huge output of a local
    Radiostation to power the lights in thair Garden.
    They used Neon-Lights and some wire. It changed
    the directional Pattern of this Radiostation
    until it was forbitten ( In the beginning there was no Law which forbits "High power Receivers" )

  5. Boiling Water Cooling on CPU Convective Water Cooling · · Score: 1

    It may be a good idea to reduce the presure in the Water System to reduce the temperature to boil the Water. This may result in a much improved efficency if done the right way (The Steam has to go up from the top of the heatsink all the way to the top of the radiator, the Water has to be allowed to flow down from the bootom of the radiator to the bottom of the heatsink)

  6. Re:i am waiting for the day... on DIY Ambient Light Keyboard Kit · · Score: 1

    This type of keyboard was available long time ago.
    It was availabe in 2 types. One with ondly a row of programabele Function-Keys and another one with LCDs on every Key (16x16 Dot-LCDs i think)

  7. Re:More usefull Power System on Green, Wireless Networking · · Score: 1

    Sorry You have to use a adapter connected to the 12V Supply, there is normaly no build in usable DC-DC-Converter in Cars. You may build your own DC-DC-Converter which isnt to comlicated if You use ICs like e.g. the LT1071 http://www.linear.com/prod/datasheet.html?datashee t=191, which is sufficent for small Laptops. You may have to add some filtering and maybe a crowbar-circuit (with fuses) for safty-reasons and to prevent EMI.
    Happy Hardware Hacking

  8. More usefull Power System on Green, Wireless Networking · · Score: 2, Insightful

    Using Power-converters for car-usage whould have saved some of the Power.Converting 12V DC up to 220V AC and back down to xxVDC (16V for the IBM-Laptopsand the Powerbooks) is much worse then direct conversion

  9. Re:Old Joke. on Overwhelmingly Large Telescope Closer to Reality · · Score: 1

    Not realy -
    It is made af some smaler Teleskops, so it is something like a beowolf

  10. Good against erosion ? on Alternative Energy: Power Via Coastal Wave Motion. · · Score: 1

    I think this may help to reduce the erosion of the costline, because some of the energy of the waves is converted to electricity. This energy no longer erodes the cost.

  11. Nice Hack, HAMs do it for years on Hack in Space · · Score: 2, Informative

    Using the Earth magnetic field is something used in Amateur radio satellites since many years.

    It is true they want clear water and foot, but it
    is always a good idea to give them everything to

    wanted by themself. Helping people to help himself
    looks almost everytime like a good idea.

  16. Re:But it worked on The Apollo 11 Guidance Computer · · Score: 1

    I think the error was because somone activated the Radar for the Randevous-manouver with the command-capsulae by mistake. The computer got to many Interrupts from this system.
