"You all did good last week," Jack acknowledged when the students filed in. "You all refused to be cuffed, you demanded lawyers, you didn't let yourselves be interrogated. That's what you were supposed to do."

On the tables in front of the class were an assortment of.. things. The more technological-minded of students might recognize signal jammers and scanners. There are also piles of random things - radios, dead cell phones, a few dead computers she'd skived from Kaidan's pile of dead computers. There's also an industrial size box of heavy-duty tinfoil she'd skived from the cafeteria.

"This week we're doing something different. The syllabus says 'tinfoil hats' - it don't mean actual tinfoil or actual hats, sorry. It's a term for paranoid types who think everyone's out to get them using spy frequencies or signals and wears tinfoil on their head to block 'em. Thing is, aluminum's a metal that actually will block certain signals and works as a Faraday cage in a pinch." She paused. "A Faraday cage is a box or pouch that's radio-frequency proof. Cell signals, radio signals, none of that sh..stuff gets through. We'll show you how to build one but first, we're gonna show you how to build some signal jammers and bug sweepers." Another pause. "Not actual bugs, radio signal spy bugs. I'll show you how to spot a bug or where to look for the places most common for people to hide 'em. We'll make squealers that'll work on a frequency only radio or cell signal will pick up so anyone tryin' to listen will get an earful of feedback."

She began going over the devices, explaining how they worked and where they were best used. Jack then pointed at the various dead tech and launched into a how-to for building these kind of devices on the fly. The students were invited to come try it out, build one for themselves. She'd be there to help. There were also packets with instructions in English and Aurebesh.

While that was going on, she explained Faraday cages and how to build those with either thick aluminum foil or many layers of thin aluminum foil, giving examples for how to hide cell phones and RFID chipped items, as well as how to signal block.
