Push Button, Receive Beverage!

Here’s a rec-room ready hack: an automatic drink dispenser.

[truebassB]’s dispenser operates around a 555 timer, adjusted by a potentiometer. Push a button and a cup pours in a few seconds, or hold the other button to dispense as much as you want.

The dispenser is made from MDF and particle board glued together, with some LEDs and paper prints to spruce it up. Just don’t forget a small spill sink for any miscalculated pours. You needn’t fret over the internals either, as the parts are easily acquired: a pair of momentary switches, a 12V micro air pump, a brass nozzle, food-safe pvc tube, a custom 555 timing circuit — otherwise readily available online — a toggle switch, a power supply plug plus adapter and a 12V battery.

[truebassB] is using a 1.5L cola bottle, so adapt your build as necessary, or scale it up to include a bar fridge and whatever beverages you want. Cutting holes in the bottle cap slightly smaller than the pvc tube and hot gluing them in place for creates an airtight seal. Once it’s all soldered together and installed, it will probably be time for a well-earned drink!

We’ve featured a few other simple yet ingenious beverage dispensers, and some that might make you question what you’re about to imbibe.
