There Is No Spoon; Automatic Self Stirring Mug

Sometimes it’s helpful to realize the truth that there is no spoon. At least, not with [Ronaldo]’s automatic self-stirring mug. At first it was just a small propeller in the bottom of the mug that turned on by pushing a button in the handle, but this wasn’t as feature-rich as [Ronaldo] hoped it could be, so he decided to see just how deep the automatic beverage-mixing rabbit hole goes.

The first thing to do was to get a microcontroller installed to handle the operation of the motor. The ATtiny13a was perfect for the job since it’s only using one output pin to control the motor, and can be configured to only draw 0.5 microamps in power-saving mode. This ensures a long life for the two AAA batteries that power the microcontroller and the motor.

As far as operation goes, the motor operates in different modes depending on how many times the button in the handle is pushed. It can be on continuously or it can operate at pre-determined intervals for a certain amount of time, making sure to keep the beverage thoroughly mixed for as long as the power lasts. Be sure to check out the video below for a detailed explanation of all of the operating modes. We could certainly see some other possible uses for more interesting beverages as well.

R2D2 drink dispenser will happily tinkle in your glass

As with Jabba the Hutt we’d like to have our own service droid to serve up a cold one. We’re in luck; it looks like you can make your very own beverage dispensing droid if you don’t mind a little awkward dispensation.

The body started as one of those big protein drink mix containers. After spraying it white and masking off the entire thing with blue painter’s tape, the shapes for the blue designs were cut out and painted. Half of a foam sphere from the hobby shop was used to form the dome.

Liquids are dispensed by the pump system from a Super Soaker motorized water gun. You can see it fill up a beaker with a mysterious blue liquid in the video after the break. It’s a long way from challenging the Bar2D2, but it’s also something a mere mortal can build

Single can mini fridge

untitled

What looks like a potential WMD, requires a huge power supply, and has several fans and wires dangling off the sides? Why a mini fridge of course! Your cubical buddy at work may have a Perfect Coffee Mug, or a USB powered fridge but it wont be as large of a caliber as [CaptPikel’s]. Little information about it is out thus far, but an Instructable is promised. We do however know that it uses 3 peltier coolers (assumed to be 60watt each) and can cool down to 46F while being underpowered! If only it held just a few more cans.
