On the popular tech news YouTube channel Linus Tech Tips, Linus has evaluated a couple of small faraday cages that are sold in the US as a way to protect home users from the harmful radiation coming from their WiFi base stations. At around NZ$120 a piece I’m not sure which of the findings I think is the funnier - that they do a really bad job of blocking WiFi, or that they turn out to just be repurposed wire paper trays with a couple of modifications to allow wires to be inserted, and that they cost less than NZ$10 each to buy from China.
