Anyone ever build a Faraday cage?
I want to shield a transformer that is 4.5 x 4.5 x 1.5 ( with PCB & associate heatsinks etc) The transformer is actually mounted on the PCB and I don't feel comfortable enough with my meager soldering skills to separate the two and shield the transformer apart from the PCB.
It gets pretty warm to the touch so heat will be an issue.
I am picturing a copper screen cage inside a hobby box. The box will be vented into a duct that will use a fan to direct heated air out of the area. Sound do-able so far?
The ground for the cage is the biggest question. Can I ground it through the power source ground or will that defeat the shielding? If not, can I ground it through my computer PSU? The reason I ask is that both the transformer and the computer PSU will be attached to the same surge-protector and I don't know enough about electronics and faraday cages to say if this is good or bad.
