This is a simple WiFi Pentesting device using a Raspberry Pi and in pt2, a cheap wifi adapter.
Step 1: Supplies
Get your supplies:
A raspberry Pi
A (fabric) Camera Case that fits your Raspberry Pi
A Micro USB cable.
Step 2: Assembly
Mark a hole where the Micro USB port is on your RasPi on your case. (I used crayon)
Step 3: Cut the Micro USB Hole
Cut the hole you marked where the Micro USB port is. Sew the edges, if necessary.
Step 4: Assembly
Put the RasPi in the Case. Make sure the hole you cut lines up with the Micro USB port.
Plug in the Micro USB cable. You can hook this up to a USB power bank, Laptop, Etc... Anything that can supply power. Now load it up with the proper pentesting software and have fun!
