- Debay’s Slough Wildlife Area Unit (wdfw.wa.gov)
The Johnson/DeBay’s Slough Unit is comprised of agricultural fields, riparian forest, and freshwater wetlands. The unit was purchased in the late 1990’s to provide an undisturbed Game Reserve for trumpeter swans as well as to provide limited waterfowl hunting area. Public access in the Game Reserve area is limited to the parking/viewing area at the end of DeBay Island Road and the mowed grass field to the east of the Game Reserve parking area. Waterfowl hunting is allowed in the portion of DeBay’s Slough to the north of DeBay Island Road and the adjacent field to the east of DeBay’s Slough.
- How did the Enigma Machine work? (youtube.com)
Let’s use 3D animation to go inside the Enigma Machine! The Enigma Machine was used during WWII by the German Army to get keep messages encrypted. It looks almost like a typewriter. There are 26 keys and 26 letters that can light up. These lights tell you how the keys will be scrambled up. The machine works like an electrical circuit. The rotors towards the back of the machine do most of the scrambling by mixing up the wiring. The plugboard in the front also another layer of encryption. Keyboard mechanism connects or disconnects the circuit to turn on a lightbulb. The path of the wire is difficult to follow so I recommend following it through in 3D! Each time a key is released - the rotors in the back will turn. This is done by the mechanism which includes the actuator bar, ratchet, pawl, and the index wheels.
