The goal of these is to have you using the parts in a small amount of time and experiment with your driver ICs, from which point you can research further into their theory and application.Īlthough these parts have been around for many years, the LM3915 isn’t used that much however for the sake of completeness we’re writing the tutorial. The first covered the LM3914, this will cover the LM3915 and the LM3916 will follow.

This is the second of three articles that will examine the LM391x series of LED driver ICs. Or, perhaps your friends are more into Jello shots.įiled under: 3d Printer hacks, Arduino Hacks If you’d rather have a cocktail, maybe you need help shaking. Perhaps, though, you’d prefer an anteater or perhaps a cow to dispense milk. Of course, you could imagine other animals, although there is something charming about the elephant. However, if you look the trunk/spout conceals some silicone tubing and that should be fine.

We are generally not fans of putting food in 3D printed objects. The steps show Fusion 360, but you could apply the same concepts using your choice of CAD programs. In addition to making it larger, they also cut off the trunk and replaced it with a spout. What we found of interest, though, was the process of starting with an elephant model and then modifying it for the purpose at hand. When you cover the sensor with a shot glass, the pump dispenses liquid. A pump and a light sensor do all the real work. The project was inspired by the ShotBot, but we have to admit the elephant sells it.Ĭonceptually, the device is pretty simple. What do you get if you have a 3D printer, some booze (or any beverage), a pump, and an Arduino? If you are you wind up with an elephant that will pour you a shot on demand. However, if you prefer your drink dispensers a little more stripped-down, you might be surprised what two motors can accomplish. Some splashing when pouring the drinks might also be remedied by adjusting the height of the tap or a fitting a nozzle.Īs cool as this old-timer beverage bot is, barbots aren’t limited to alcohol - tea is a viable option. In a future version, wants music to play and the lights to flash different patterns depending on the drink being poured, as well as the option to serve multiple drinks in sequence.

Here’s a more in-depth tour of what’s going on behind the bar, but check out the video after the break for a full run through of a few drink orders! A Raspberry Pi acts as this old-timer’s brain, an Arduino controls the lights, and a HAT to controls the servos. A belt-driven drink loading platform pushes out through a spring-loaded door and once the vessel is in place and the order received, peristaltic pumps dispense the spirits while servos open taps for the mixers - a far easier method to administer the often carbonated liquids. This bar-clock can dispense beverages with up to four different spirits and four mixers, and takes orders over voice, keyboard, or web-controls. As the saying goes, it’s five o’clock somewhere when the clock finally strikes the hour, that same clock can pour you a drink thanks to redditor.
