Mostly for a bit of fun but I actually want to put together some extremely discreet surveillance equipment as well as some pentesting hardware.
Stuff like good quality pinhole wifi cameras with battery packs that you've hidden or built into other objects or any hardware which can be used to dump on a network and remotely accessed to gather info etc. Shit like that.
Post pictures of anything you've bought, also, what's the most dangerous stuff you've seen on them, shit that you could modify yourself into something other than that which was originally intended etc.
If not, just general personal projects you're proud of thread will sate.
