IKEA Molgan is a battery powered night light with a built-in motion (PIR) sensor. This hack describes how to add the ESP8266 WiFi module and use it for motion detection and remote notification through Internet. My original plan was to use an cheap Ebay PIR and 3D printed case for this project but I happen to have a spareIkea Molgan PIR light lying around, I opened it up and take a peek inside and decided to work this hack with it, overall this is an attractive and cheap unit. Removing the top dome was easy as it is friction fitted and

Nick Johnson from Arachnid Labs has designed a powerful and affordable signal generator (named Tsunami) based on the Arduino platform, and is now running a Kickstarter for making it available to electronics hobbyists worldwide. The Tsunami is a powerful and flexible signal generator built on the Arduino platform. It’s the best way to get started experimenting with analog signals, and a great tool for a huge variety of tasks, too. The tsunami takes the versatile processor behind the Arduino Leonardo, and combines it with a Direct Digital Synthesis chip, which makes generating analog signals incredibly straightforward. It also has flexible input and
