The conductive paint on the inside of an Apple IIe's plastic enclosure got me thinking: what's the best way of shielding devices in plastic enclosures if your production runs are so small that
conductive coatings are not cost-effective due to the time and complexity?
Nickel-copper conductive fabrics were once used for this but I haven't seen a device with them in a while. They're also available in tape form.
What do people end up using for thing like homebrew test equipment?
