For those living in a magical land of candy, with orange-faced helpers to do their bidding, the ability to taste your words is nothing new. But for the rest of us, the ability to taste what you type in cocktail form is a novelty. [Morskoiboy] took some back-of-the-envelope ideas and made them into a real device that uses syringes as keys, and facilitates the injection of twenty-six different flavorings into a baseline liquid. He figures that you can make each letter as creative as you want to, like representing different alcohols with a letter (T for tequila) or matching them to colors (R for red). Check out the video after the break to see an ‘Any Word’ cocktail being mixed.
This setup is entirely mechanical, and makes us wonder if [Morskoiboy] works in the medical equipment design industry. Each letter for the keyboard is affixed to the plunger on a syringe. When depressed, they cause the liquid in an external vessel (not seen above) to travel through tubing until it fills the proper cavities on a 15-segment display to match the letter pressed. From there the additive is flushed out by the gravity-fed base liquid into the drinking glass. We can’t imagine the time that went into designing all of the plumbing!

[Ben Krasnow] is working on a force-feedback joystick. It centers around the concept of an air muscle which transfers pressure into linear motion. He cites another air muscle project as part of the inspiration in his build, but where he’s gone with it is one of the better uses for these blow-up components that we’ve seen.
Basically you have a bladder, in this case rubber tubing. A mesh surrounds it to reinforce the material and cause inflation to shorten the length of the package. In the image above there are four black air muscles that connect the base of a joystick with the outer frame that houses it. How and when each muscle is pressurized determines the type of motion the user will feel on the joystick. This is where his pressure controller comes into play. It uses a voltage-to-pressure transducer to feed a manifold, the combination of which not only makes each muscle addressable but allows him to dial in the force sent to the muscles. Check out the video after the break for his start-to-finish walk through.

[Qdot] came up with a simple way to dosing out liquids to use in his Bartris project. As you can see above, flexible tubing is connected to some inverted bottles that house the liquid. A chopstick is attached to a board on one end, and via string to a servo on the other. When the servo turns it pulls the chopstick tight against the board, cutting off the flow of liquid through the tubing. This isn’t as elegant as the system the Bar2D2 uses but it’s a heck of a lot less expensive.
You can check out some of the build pictures in his Flickr pool. He’s included this concept in a project he calls Adult Mario. Watch the video after the break but the quick and dirty is that the more coins you score in Super Mario Brothers, the more beverage is rationed out into your cup. Ah, human lab rats, is there nothing they won’t do for booze?
