"The Seg-bot is a DIY segway clone that costs around $500 to build. It will attempt to keep the rider upright at 0 degrees (level), so if you lean forward it will travel forward to correct its position – the farther you lean, the faster it will go to correct itself."

"To build this tool I’ve used two old CD-ROM writer that lays around in my garage. The X/Y positioning system it is build using the CD-ROM motor assembly. For the engraving laser i use the CD-ROM writer laser. With this hardware the engraving area are will be almost 38mm x 38mm."

"Back in late February I saw this post on the Raspberry Pi site: http://www.raspberrypi.org/school-weather-station-project/ . They had created Raspberry Pi Weather Stations for Schools. I totally wanted one! But at that time they are not publicly available. Well, I wanted on and I didn’t feel like shelling out hundreds of dollars for an existing 3rd party system."

"…I have received a few emails asking about controlling a toaster oven using the laminator temperature control board. This is something I have been thinking about myself, so I decided to buy an oven and convert it into a SMD reflow oven. If you decide to do this, do it at your own risk and make sure you, your family, and your friends know to never use it for food!!!"

"The presented home monitoring system consists of a star like structure of wireless nodes. This means that one node, the main node, collects information from the other nodes and forwards them to Raspberry Pi. The other nodes act just like wireless sensors – periodically measure physical values around the flat and send the measurements to the main node. "

"The platform, using dual element PIR sensors, rotates itself independently to direct air flow to whatever position a person moves to. In addition, the fan includes another setting that allows precise rotation between two people. These modes are selectable by the user. The running mode is displayed on an LCD."

"The Odhner Arithmometer was a very popular pinwheel calculator invented in Russia in 19th century by a Swedish immigrant called W. T. Odhner. Like most of pinwheel calculators, it worked with an engine formed by a set of linked wheels which could perform the four basic mathematical operations within a machine of reduced size."

"In some cooking scenarios, it is desirable to achieve a specific object temperature and keep the object at that temperature. However, it is difficult to maintain a constant temperature without constant attention. To aid cooking in this scenario, we created a device that can be added to an electric stovetop or hot plate and serve as an automated assistant."

"This project describes how to read the speed of a PC fan using Arduino board. It’s a good introduction to reading pulse duration and driving 7 segment led displays on Arduino. The text is written in Japanese but the link below will auto-translate to English."

"The goal of this project was to create a robot which could erase written text on a whiteboard completely autonomously, i.e. no human interface. The processes involved in this project included devising a method for the robot to search a whiteboard for text, designing a way to physically move a robot to the text, and enabling a robot to erase the text."
