  1. so as the electron pass these cavity things inbetwen the anode it cause them to resonate and that force a small amount of force to the metal tube which cause electromagnetic waves right?
  2. im still not really understanding what happens inside these cavity things how the electrons are changed into waves
  3. that the links are great but im having a bit of trouble understanding how the magnertron works i know that current flows out the hot filament and the spirals around befor getting tothe anode becuase of the magnetic field but im not sure about how the rest works how the current goes into the cavitys and stuff ahppens in there which makes the microwaves. can someone explain in a grade 11-12 level for my assigment thanks in advance steve
  4. hey guys im doing a school physics project on how a microwave oevn works and im going to go in to a fair bit of detail of all the electronic components like the high voltage transitor and the special light needed and all about the magnetors. so i was after a service manula on any moden microwave oven and i was also hopeing to find a explosion diagram of a microwave oven so any help at all about this assigmnent whould be great if you got any links to sevrice manuals that would be great to thanks alot in advance
  5. as I am cheap I bought a broken keyboard from el'cheapo's discount varity store for only dollars to the amount of three. I managed to fix the keyboard with a quick solder but the keyboard has an inherent flaw, being that the company which designed the keyboard, in it's infinite wisdom decided to make the black keys make the same noise as the white key next to it. I was wondering how I would go about rectifying this minor design flaw. basicaly it just wired up with a row of risitors and pressing the key just completes the circuit. depending on what key your press ajusts the total resistance. any assistance with this problem would be greatly apperciated. thanks spleblem
  6. hey guys is there any point to a zero ohm resistor :-\ :-\ :-\ :-\ thanx spleblem
  7. hi you could try putting a small push off unpush on swith on the inside near the lid to when you lift the lid it turns on [move]spleblem[/move]
  8. hi yes the parralax boe is probally the best thing that you could buy to get started i want to be a mech eng when i leave school im studying physics but i been mucking round with electronics for years deafently buy the parralex boe i always wanted to buy it but now i now all about it and it would be boring for me now [move]spleblem[/move]
  9. what sort of display pannel are you tying to make
  10. hi all readers i have just made a doorbell with programable tunes using a picaxe 08 chip and im wondering if any one knows any other tunes than christmas tunes or how to change a tune in note for or maybe a program to change mp3 songs for the format that the picaxe 08 will exept thanx [move]spleblem[/move]
  11. yes i understand all that but i think if there was a area for component swap and just compnent swap it would be more clear to all users [move]spleblem[/move]
  12. but drawing the art in this program is much easier and quicker to use than most others. [move]spleblem[/move]
  13. but why cant there just be a new area made for swapping componets then i think heeps of people will use it [move]spleblem[/move]
  14. hi all there is a really easy pcb editor called pad 2 pad and it 100times easier than eagle pcb just google search for it [move]spleblem[/move]
  15. if you want to view a .pcb in paint open the pcb in a pcb editor and press the print screen button left of scroll lock on the keyboard go in to paint a press paste [move]spleblem[/move]
  16. i think dazzas idea would be a great idea and i hope to see it up and running some time it would be great i have heeps of old components and some times need componets which arnt sold in my country [move] spleblem[/move]
  17. what extra things do u do being a mederator? [move]spleblem[/move]
  18. well i tryed if there any changes u wont just open in paint draw them on and ill try and fix for u or just tell me what u want fixed
  19. ill try for u but do u want the optional part for the circuit [move]spleblem[/move]
  20. ok thanx ill try using 2 2n2222 in parallel thanx a lot [move]spleblem javascript:replaceText(' :o', document.postmodify.message); Shockedjavascript:replaceText(' :o', document.postmodify.message); Shocked javascript:replaceText(' :o', document.postmodify.message); Shocked javascript:replaceText(' :o', document.postmodify.message); Shocked javascript:replaceText(' :o', document.postmodify.message); Shocked [/move]
  21. thanx but that in america and the postage would be heeps to much i dont got to much money do u think there might be a dirrernt name for the component which might be use in australia kangaroos are great all ways jumping around on the town roads [move]spleblem[/move]
  22. thanx then is there any other more easier transistor i cant get the right one any where here in australia
  23. [shadow=red,left]for the transistors would a 2n2222a work becuase thats the closest i can get[/shadow] [move]spleblem[/move]
