carbon fibre ?copper foil ?normal aluminium foil ??conductive fabric ? silver paint/copper paint applied to material ?? Which works best ??
you ought to income out youtube with mousetrap automobilean excellent variety of video clipsI made a form of ultimate 3 hundred and sixty 5 days out of a moustrap and 2 paint stirring stickslisted under are some tricks: -steel axles in eye bolts artwork properly to cut back friction -the attention bolts could be smalltoo lots mass kills distance and acceleration-get some super balloonscut back slices of balloon (like a rubber band) to place around the wheels for traction- you ought to use duct tape to mount cd's on the axles, yet you have placed sufficient on, and then slowly trim it to in effective condition, bit by utilising bitsturdy success.
Of the choices you've offered, the copper foil is the BESTIt's best because it is 100% shielding, unlike wire braids or screens and because it is the best conductor, only second to pure silverIt's more difficult to work with than mesh if you need irregular shapesAluminum is only 62% the conductivity of copper and difficult to bond, unlike copper which will bond with solder and low heatHowever, for the application you're mentioning, any conductive enclosure will work equally wellFabrics? You'd have to test themWhat conductive fabrics are you speaking of if not wire mesh? I wouldn't rely on coatings or impregnated materials.
