Steganography Tutorial - Hide Messages In Images
Steganography is the hiding of a secret message within an ordinary message and the extraction of it at its destination. Steganography takes cryptography a step further by hiding an encrypted message so that no one suspects it exists. Ideally, anyone scanning your data will fail to know it

How to Make a Full Auto Airsoft Mini Gun [Halo Inspired Mobile Turret]
This is a type of cloud airsoft gun - named so because of how the pellets are blown around the reservoir before being fired out the barrel. Since there is nothing mechanical to get in the way of the workings of this gun the rate of fire is extremely high, an estimated 50 rounds per second.
