Have you ever had a sudden desire to create a device that posts your energy usage online through twitter? Limor Fried did, so she hacked a Kill-a-watt power monitor to wirelessly send data to a computer. Her addition to the device is engineering wireless transmitters inside the power monitors, which are placed in each room of a home, to log data on how much energy is being used. A kit including all necessary items and instructions on how to build the device is available on her company’s website, Adafruit Industries.
If drawing with a plain pencil isn’t exciting enough for you, Lady Ada and Jay Silver’s Drawdio device might be just what you need. The device takes advantage of the conductive properties of pencil graphite to create interesting sounds while writing. This is the perfect project for anyone who wants to learn about electrical engineering and annoy everyone around them at the same time. Check out this video to learn more about the Drawdio and see it in action.
Ice Cube Clock
This is a more advanced kit because of the dangers of generating a high voltage. This design, by Lady Ada, is for a retro alarm clock in a Russian display cube. The picture is dark but the intricacies of the alarm clock can still be seen. Since it’s an advanced kit, this project is a great example of an open source product that can be hacked and modified however the owner sees fit. Check out the design here!
