  1. yeah i mean muscles in thinking would be like sticking a spanner(read: asking for a spinning hard drive platter) in a processor. Processors don't have moving parts now do they? Same way, while thinking we don't need muscles or anything. Just like 10001010101011101001010.....keep streaming through the processor back and forth, the same way the energy impulses keep going past the brain's processing unit back and forth to make us "think". Although I "think"(get it?) that when one thinks of a certain problem mentally, a lot of complex and trial & error simulation is done in the brain. That's thinking I suppose.
  2. I see something funny, are both left in the same room?
  3. that was sooo funny... he weighs fish. How about this: consider, Mass of Tom=m Mass of Earth=M Newton's Gravitational constant=G Acceleration due to gravity=g Radius of Earth=R We know, F α Mm/R^2 F=GMm/R^2 GM=F(R^2)/m where F/m=g therefore, GM=gR^2 Let Tom be at a height h from the surface of the earth, GM=(g*)(R+h)^2 g*=Gravity at height h above earth's surface. Therefore weight of Tom W, W=(g*)(m) Final answer W= (g*)(m) Now considering Tom moving at a velocity v, where v is not neglible compared to the speed of light c. We know m0= (I'm getting bored now, anybody care to complete it?)
  4. CIA is allowed to use it on suspects forcefully, but we are allowed to use to heighten creativity or get any new ideas or breakthrough? Talk about hypocrisy...
  5. in reply to the original question, I personally feel that like the computers process things in binary, our brain also has a "system" or "language" of processing information. Maybe I'm not able to express my thoughts clearly, but doesn't the base system depend on how many types of impulses are present?
  6. i saw the link, both of them... you're telling me to build the one with the "Bill Bowden" name right? yah, well i do think that it needs an additional winding, atleast thats what is shown in the schematic... So where doth ye transistor goeth?
  7. ok but in this supply there seems to be no way of varying the output voltage. And by the looks of it, it seems to require 2 transformers which ends up escalating costs... And I didn't quite understand where to put the 2n3055 in the ckt that i showed you...
  8. Ok, so you mean that i should replace the LM317 with the 2n3055? I wanted an LED readout coz i wanted to mount it in a metal case. So i still ask, any IC or circuit to electronically get the voltage reading, which can be displayed on the 7 segment?
  9. http://www.uoguelph.ca/~antoon/circ/vps.htm I am planning to build a power supply as shown in the above page. Only there are 2 problems... 1. The power supply is rated at 1.5A, I want it to work at 5A or atleast 3A so what modifications should I make? 2. I don't have a voltmeter so I want to know if I can use some ICs to hook it up to a 7-segment LED for a digital readout? (Doesn't matter however complex)
  10. oh ok, now i got what you said. The other propellor will have to be reverse right. ok i'll try to keep that in mind now. Man just think me trying hard and getting no result You mean everything else is ok right?.... And any links on the 2 prop helis, coz i couldn't find one at all...
  11. This is my idea, simple schematic It's going to be wired first I'll see wireless later like after getting this right...
  12. ok but is my logic about turning correct or am i missing something?
  13. actually what i thought of the two rotor was more like the military choppers. one in the front and one in the back. i thought there would be no need for a gyroscope as the front and back rotors would stop the heli from spinning. Here's my plan for the build: 1. Get 2 of those motors. 2. fix a propellor to each of those 3. keep distance between them using some cardboard, masking tape, and styrofoam. 4. Connect them to fan regulators, SCR based(one for each motor). This will help in controlling the speed of each motor individually i.e. for turning, and moving forward. 5. Have a third regulator that can control both the motors simultaneously. This can be used for climb, hover, and descent. 6. My basic plan is to connect the 3rd regulator in such a way using a toggle switch that either the first two function, or the third functions. *Will I need two propellors of EXACTLY same characteristics for my above design? *Will an SCR based regulator work in DC voltage, or will I have to use a potentiometer? Here's my plan for the flight: 1. Toggle the common switch, and increase power to the regulator 3. 2. When it reaches the desired height, slightly lower the power to maintain constant height. 3. Toggle the individual regulators 1 & 2, to control the heli. 4. For forward flight slightly increase the power of the back motor more than that required for hovering, and converse for backward flight. 5. For turning, i dont know how it should work, but i guess that if we decrease the power of one motor, torque will be generated in the other and we can use that to turn. I think for this to work effectively both motors should spin in opposite directions. *Will this entire plan workout?
  14. Any place where i can find information about helicopters with 2 propellors you know the two fan ones. I'm planning to make one (wired) with 2x 15000rpm 12v motor and some thermocol(styrofoam) and two plastic propellers. Any tips or suggestions. Also will the fan regulators(SCR) work in DC.
  15. Does this mean if we magnify an electron many times, we can actually hold it in our hands, ie is it as physically present as much as a couch or a chair?
  16. but some time i think that water will rise at the same level, as pressure at the bnase is same in both pipes, and initial and final pipe radius is also same
  17. is there any magical device that would convert DC current to AC current? i.e. Give a sine wave output for a straightline input.
  18. I suppose the one in the 15mm will go higher. Since it's diameter is lesser, the water will have greater velocity I guess...
  19. [sarcasm] Hey I created a perpetual Motion machine that works at 1000% efficiency, it takes electricity from the socket and creates lots more. I'm currently distributing it to the Electricity board, and i'm getting richer day by day. Bill Gates, here I come. [/sarcasm]
  20. well i think it's called styrofoam, the white thing that's light and can be only cut properly with hot lnife or something hot. If cut cold, it doesn't get cut properly, but instead into large granular things. Well i dont know what you call it properly but over here it's called thermocole, or am i missing something.
  21. oh, then mathematically it'd take us a long time, BUT we'd arrive at an answer. I'll try it out and then post it here.
  22. I want to pulse a set of 6 LEDs. It should be one led at a time, not all 6 together. There is a site that shows how to pulse a single LED, but how do I get to pulse 6 of them, actually even 4 will do. The LEDs will run off a 3.7V @ 1070 mA. I tried to think of a simple solution without messing things up as space is also a constraint, but I ain't getting nowhere.
  23. what'll happen if you use thermocole. It'd be super light. And you could tape it up for re-inforcing the 'cole.
  24. can't we draw a scale triangle and get it done?
  25. i've been getting these since a lightning hit or something on our building since jan. Before that my PC ran at 1667Mhz which is 133 x something. And I've got DDR which also ran at 133Mhz FSb. But then after sometime, my mobo capacitor blew up, which i got fixed. And after that I've not been able to run at full speed, but at a 25% loss. All my stuff are legal, right from XP pro to Lemming Ball Z, to flight Sim etc etc. So there's no need to worry about that. It's sad that i cant screen capture BSOD in XP.
