wilba - when i get home i'll send you my bookmark. quick shipping, real cheap.

yeah man it's useful stuff, i was gonna mention that but completely forgot. there are some funny images out there...

JEEZ man mcmaster is amazingly specific, this is amazing...

thanks! i will be checking these out immediately.

hey ladies and gentlemen. i ran a search on this and didn't seem to find it, so i thought i'd share the wealth. i have discovered something awesome that you should know about. it's called VELOSTAT, and it's an EMF shielding, carbon-impregnated plasticy film. the cool stuff about this junk is A, it's only 1.99 for a yard of it, and B, when you hold it against a active surface, it only becomes conductive once you apply pressure - and grows less resistive as you apply more pressure. this could be very very useful in a lot of home applications. if you haven't read my other post, i'm using it to repair mpc1000s with bad pad designs, but i imagine it could be used for making totally sealed portentiometers, etc. if anyone's intersted in this stuff please post, and i'll throw up the link to a good quick place to order it. glad to make your aquaintance, hope to frequent these boards a lot. VERY happy to have found such a cool community.

hey folks, first post. i was introduced to this place by modnar from the mpc forums, and from a very brief search i realized almost immediately that this forum is RIGHT up my alley. here's my story - i'm rebuilding the mpc1000 pads, notoriously bad and famously flawed. i'll tell the full story in another post and link you to it here. but this is my question. i've found a material that allows for variable resistivity (velostat, son) but now i'm looking for something more simple -- sheet rubber w/ a shore hardness of about 50, give or take 10 to 15 on the durometer scale. i've done some initial googlin' and found a lot of custom order people, but i'm just lookign for some feedback from you guys as to stores you've worked with, etc. we're just talking about a solid sheet of rubber/whatever of about 1/8th inch thickness. any lenth/width is fine but of course i'd prefer not to buy in huge bulk til i know it works well. thanks! can't wait to hear your thoughts. nym
