  1. First thing that I would suggest is Arduino. If you are thinking about getting more out of uC then you can use arduino platform but program it with C. Later gives you more insight to what processor has, but also takes more time to learn (underestanding the internals of the microprocessor) I am not a big fan of PIC, but it is good thing. Get some servos for locomotion. modify these to rotating (info in the web) and then something to get signals from world like ir rangefinder. And ofcourse you need battery. That would be good start from the hardware. IF you decide to go with arduino or avr programming, head out to arduino forums or avr-freaks forums to get start-up tips. That should do it.
  2. I have done a bit of googling but I did not find what I was looking for. I will read from the knot and see what happens.
  3. When I read the title I was thinking. BLDC motors. Technically all the electric cars are on magnets. Also, Xittenn, I want to see that article about BMW seed concept. Sounds like awesome read!
  4. Good day. I was working on my set theory home assignment when I found out that I got no useful knowledge on how to construct proofs. I all ready have tried reading about proofs and making sure I can read simple proofs (As should be the one I need to construct) but now I have understanding that I do not have any real understanding about what proof exactly is nor how it should be formally constructed. That is the reason I am here. I would like to get some tips and ideas on how to understand proof and help on working my way to create proofs. PS, I am a University 1-st year student and actually have really bad math background. Also, I have been working on electronics and mechanics during my vocational training. Which means that I have 2 years between high-school and university... I feel it now. Also, the date for the homework is not Sunday (as people usually come for help when the due date is tomorrow.) but the 8-ht of November. I believe that my involvement in the ESTCube ADCS subsystem managing should excuse my late waking on the homework. Thou 4 days should be enough to be able to create simple proofs. I do thank in advance every one who will bother themselves with trying to help me and also am sorry for my bad English as it is not my native language. Best regards, Markus Järve
  5. I think i get what he means. If time is movement of an object and relative, how can there be constant in speed wich is measured by time and distance? I have had question like this aswell... Google says that: Time is... an instance or single occasion for some event; "this time he succeeded"; "he called four times"; "he could do ten at a clip" a period of time considered as a resource under your control and sufficient to accomplish something; "take time to smell the roses"; "I didn't have time to finish"; "it took more than half my time" an indefinite period (usually marked by specific attributes or activities); "he waited a long time"; "the time of year for planting"; "he was a great actor in his time" a suitable moment; "it is time to go" the continuum of experience in which events pass from the future through the present to the past clock: measure the time or duration of an event or action or the person who performs an action in a certain period of time; "he clocked the runners" a person's experience on a particular occasion; "he had a time holding back the tears"; "they had a good time together" assign a time for an activity or event; "The candidate carefully timed his appearance at the disaster scene" clock time: a reading of a point in time as given by a clock; "do you know what time it is?"; "the time is 10 o'clock" set the speed, duration, or execution of; "we time the process to manufacture our cars very precisely" fourth dimension: the fourth coordinate that is required (along with three spatial dimensions) to specify a physical event regulate or set the time of; "time the clock" meter: rhythm as given by division into parts of equal duration adjust so that a force is applied and an action occurs at the desired time; "The good player times his swing so as to hit the ball squarely" prison term: the period of time a prisoner is imprisoned; "he served a prison term of 15 months"; "his sentence was 5 to 10 years"; "he is doing time in the county jail" And oon we go. Anyways. Science daily says that it comes out in a motion (http://www.sciencedaily.com/releases/2005/04/050415115227.htm) but in that case... well. i still dont get all of the time consept. I hope it is like something the question that north had only little more clear. And yes. it could be named as: What is time.
  6. And if one has read A.C.Clarke i suggest to move on to Isaac Asimov. (If have not allready) These two are the best ever.
  7. Now i get it . Thank you. I got the right answer as well. But all ready i got new problem. (dam i should have paid more attention three years ago.) I'll try to get to the end of that one without help. And if i can not, then i'll be back
  8. well as i said. my problem is not that i need answers. I am studying for exams and found that there are things that i can not do a thing to. i don't see what i have to do with such exercise. And due to holidays i do not have possibility to consult with my teacher. I was hoping that someone could show or explain me how such exercise should be solved.
  9. I am sorry to stick my nose in here and start talking, but isn't "C'est la vie" thats life? I am not sure i get the meaning of cei life. I know, that it is not in the topic but i just can not help it. Just shout at me when i get annoying
  10. Well. I am using chrome. It feels smooth. When i am surfing i can feel that i am using my internet not that it all is stuck on my CPU. Opening times compared to FF is about 5 times better. Even after i cleaned my PC. I had problems with youtube videos at the beginning, but by now i don't see any problems anymore. I love the look and feeling of the Chrome so i will be using it for a long long time.
  11. If car would drive 15 km/h faster it would get to point B one hour earlier. If 10 km/h slower, it would take one hour more. Must find the speed of the car and distance it was driving. I am really embarrassed, because i knew how to do it about 3 years ago. But totally forgot it by now. I can give answers, but i need to know how i can get the answer. Thank you all.
  12. Hello. I got a math problem. ( It should be easy for most of the people. Even me but i missed the class when they were looking at that) On a chess tournament every chess player played one time with every one. in total there were 45 chess games held. How many players were there? I just can not figure out what i should use and how to find the number of players. EDIT: I allready got it. I have to use Combinations formula and it all works out Before i just could not find the right way to use it. But still if someone got good ideas to use for this i'd like to hear them.

    cannabis

    well. actually getting high on nicotine is rather easy. and it does slow down reaction speed. i know because i was heavy smoker for a year. but it is said to fade for long term smokers. they usually stay on the brain reward system (dont know what its called in english) so that bigger concentration of brain released opiates due to the nicotine (like endorfin etc) makes them feel good and relaxed. i hope i did not miss anything here... EDIT: i wonder why people dont use physical training. those amounts of endorfin gathered from there are huge. and feeling after the training is quite close to feeling after sex. weed high can not be close compared to that.

    cannabis

    yes. thats for sure. i just wondered if someone knows anything about cannabis that really is worse than tobacco. anyways i will keep close look on people who use weed.
