Bit of a long shot I know, but I'm really struggling with this one - I'm trying to get hold of a sheet of (ideally) conductive or (second best) static dissipative plastic for a home project (not commercial), around 5 or 10mm x 1m x 1m, does anyone have any ideas where I might be able to get some? I know it exists, but can only find it on manufacturer's websites so far, not on small scale distributors. Or any ideas for other rigid resistive material that can end up about 40mm wide x 5mm thick x 1m long? I'm happy to pay for it, but of course I'll only be buying the one sheet, not a tonne!
It's for something vaguely along the lines of an Ondes Martenot - I do enjoy building weird musical instruments - over the holidays I managed to lash up a prototype using an antistatic bag (the black type used for IC tubes) bonded to a piece of wood, which showed the principle works. But it also showed it needs something a bit more flat and rigid to work reliably.
All help and leads gratefully appreciated!
The actual fibres conduct, but I don't know the properties once laminated. Might need some sanding, or be a bit uneven?
Also, given it's only a bit of fun (and an experiment which might not work) I was hoping for 10s of pounds rather than 100s 😀
I have just managed to get hold of a small sample of Polyethylene UHMW Anti-Static PE1000 Sheet, too small for what I need but will at least show whether it's got suitable surface resistance.
I'm thinking of the flooring systems used in such places as explosive processing areas - most of the big flooring manufacturers will usually be happy to give you a sample
Good question, I'd prefer conductive as it'll give better noise (EMC) rejection, but dissipative would be ok - it's very much a case of beggars not being choosers! Ideal would be 10's of kilohms over my 1m length, (of 40mm x 5mm ish)
Excellent idea about the flooring, I'd never have thought of that, with a few seconds of Googling after that hint I think I may have found just the thing 🙂 Here's a first virtual pint to all for the help 🍺 I'll post a video on here along with a second virtual pint if I ever get this beast working...
Dissipative flooring is more in the range of 1 x 10^7 through to about 1 x 10^9 - this is for more general use where you might have "ordinary persons" present - ie ordinary footwear
Some manufacturers (polyflor being one) do have some pretty low resistance flooring sheets (but they need very careful application as a flooring product due to shock risk) - for your application that wouldn't (presumably) be a risk though
Hope that helps
for your application that wouldn't (presumably) be a risk though
Yes, provided I remember not to try playing it with my tongue the 5V shock risk should be ok 😁
