If you live in a house that has more people than washrooms you have probably come across the situation where you are waiting for one to free up. Sven has come up with a solution, use a microcontroller to capture usage information and graph it so that you can see what the typical usage patten is like! Have a look at the recent graphs for some additional details. "This project is about nearly daily statistical analysis and reporting of loo usage. Ever wanted to know when is the best time to go to the bathroom?

Driving motors from a microcontroller will be required for a project eventually. This video by NerdKits will go over some of the basics that are needed. Thanks Humberto. "Electric motors are a key way of converting electrical power (voltage and current) into mechanical power (torque and speed), and because electric motors are simple and reliable machines, they can be found all over, in many different shapes and sizes. In this video tutorial we’re just going to address the electrical side of the system. This includes some experiments you should try with a DC motor, a model of the system from an electrical perspective, building a MOSFET-based switching circuit, and finally two demos of a microcontroller-operated motor. This video and webpage specifically addresses a brushed DC motor, and although the specifics are not fully applicable to brushless (BLDC) motors, stepper motors, or AC motors, the big ideas about motor modeling and control will be useful in those areas as well." |

If you have some top secret into that needs to hide in plain sight have a look at this USB Cigar. When the cigar is together there is no sign that it has been hacked! "Materials:

Computer generated special effects seem to be getting better and better by leaps and bounds these days. I have watched the first video at least 6 times and can’t seem to find any flaws in it. I am still a pushover for real innovation thought like this video of the Sony QRIO Baseball Pitcher. |

The goal of this project is to get an overview of the bathroom usage and to get an idea of the loo usage patterns. With the help of statistical analysis it should be possible to get the desired information on a mathematical foundation. For that purpose an electrical switch is attached to the bathroom’s door’s lock. When the door is locked the switch is closed thus closing a circuit and igniting "occupied" lights in the rooms. This information also flows to a microcontroller that registers the status change and writes this information together with a timestamp that comes from a radio controlled DCF77 clock module into a file on a USB storage. This file is being read into a database a web application server is connected with. A CherryPy web application server contains all the the logic to evaluate and report the desired information as flash charts."
