Use Tails OS usb booted and learn about onion browsing with tor + raspberry working like a middle router (like a vpn thing but better)
Connection example:
Your pc (tails OS --» tor browser --» Connected through ethernet to raspberry py --» and finally raspberry connected to a wifi network, do not use your own house internet/wifi, if you live in a city try self service laundries free wifi and coffee's but careful not all are safe)
Your laptop must be prepared.
Cut wifi receptor, bluetooth receptor, microfone, webcam (do not just disable them, cut them off the laptop) * attencion only the raspberry have wifi reception
And search a little bit more about being anon.
