The Loquino is a Loquacious Arduino, a small box with a large vocabulary.

When the Loquino turns on, it briefly shows a splash screen then starts displaying random words. The words are chosen from two sources.

"Real" words come from a highly compressed list of over 1800 entries from the "Grandiloquent Dictionary" found here. and used with permission. These words have been compressed using Huffman coding (variable-length bit sequences).
"Fake" words are generated using Markov chain theory (pseudo-English words are generated using letter-triplet probabilities found in real English words.) Fake words are displayed with a question mark.

Beside the USB connector is a hole providing access to the LCD contrast adjustment.
On the other side of the Loquino are two buttons. Pressing the upper button (Set) puts the Loquino into configuration mode with the settings listed below. Pressing Set advances to the next setting. Pressing the other button (Sel) changes the setting.

  Words: Both, Fake or Real
Selects displaying both categories of words, just Fake, or just Real.

  Power: Batt or USB
Selects the power source.

  Light: Off/[######... ]
Sets the backlight brightness. Only available when Power is USB.

  Delay: Min/[######... ]
Sets the delay between words. The minimum is 8s.

  Sleep: Off/[######... ]
Sets the ambient light level below which the Loquino will Sleep. If the level is not Off, the flashing cursor shows the current light level. Only available when Power is Batt. The idea is to have the Loquino save battery power by sleeping when the environment goes dark.

  Wake: [######... ]
Sets the ambient light level above which the Loquino will Wake. The flashing cursor shows the current light level. Only available when Power is Batt and Sleep is not Off.

  Randomize: Off/[######... ]
Used to re-randomize the Loquino. If a value other than Off is selected, you will be prompted for three more values. These 4 values are used as a seed for the pseudo-random number generator.

  LOOP=nnnn
Information only. Displays the number of loops the Loquino has performed (displaying words or sleeping).

Notes:
Button responsiveness is not ideal. Press the Set button for a while to enter configuration mode. Then tap the buttons confidently.

I don't know how long the Loquino will last running off batteries.
