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.

New Project: Limit TV Time with an Arduino-Controlled Relay

Most of us spend far too much time in front of the TV. So I designed a system that will automatically limit when and how much the TV can be on.

DIY Star Trek Automatic Door

Who hasn’t dreamed of have a Star Trek style automatic door in their home (complete with “wooshing” noise)? Now you can build your own with the help of this DIY project and some pneumatics. The pnematic system uses an air compressor, a piston, valves, hoses, infrared sensors, and an Arduino.  The best part about the pneumatics is that the “woosh” noise comes built in – No special effects department needed!  Check out more details about the door.
