just wanted to try and combine some topics (except for that damned philosopy section ) and try to recruit some help assembling the little gizmos I have into a moving electronic object of some sort that we can all participate in . I need participation in the following areas : * good ideas with what could be done with the ingredients I have (once I give a detailed list of them ) * a research and post about the physics behind the individual items , history of discovery , technical info and such . To start with : I was hoping if anyone was interested that they could help to give a short lesson in thier own words with links to references of the individual items (instead of just links) . Then when all are equally informed , to start throwing ideas around and see what we can cook up ! * Disclaimer : no ideas for explosive devices will be considered ( and I will tell on you !) , some dry cell batteries may be harmed in the assembly of any potential project ( no PETB comments please) . I will hold no one responsible for any damage that may be caused to my landlords house(including myself) . So if anyone is interested in sharing thier knowledge on the ingredients and help to inform others , please drop a line ! Looking to recruit the likes of : Waxy , Zsand , Mizar , That Russian kid and bode----->Check out his Science site : give you some things to think about... Topics and items to be described : piezoelectric effect /piezoelectric disks , Capacitors / farads /coulubs , Selenoids/electromagnets , Motors(wound,permanent magnet) , dry cell batteries , Magnatism / rare earth magnets and electromagnets , OHMS Law , and much more . I just realized I have to shut the computer down to install a couple usb ports , but I will post links to pictures of the items for reference as soon as I hit " post new topic" The items are (ofcourse) : wire , piezoelectric discs , rare earth magnets , selenoids , capacitors , hobby motors , batteries , bike wheels , metal chains , steel bands , sealed bearings from rollerblades and bmx wheels , axels , more wire , individual peices of quartz . All sorts of shapes and sizes of most items...... shoot some feedback to this post and since I typed it out for all to see , we can hope this is an acceptable proposal for the science fair and physics section . Just an excitable boy , sorry to the mods if i jumped the gun ! Stay tuned !!
