Infra-red controlled smart AC outlet

Infrared remote control for home appliances is a popular project among hobbyists and students. Smart Outlet is a similar project that provides an infrared controlled AC outlet to connect any electric appliance and has an integrated timer in it. The appliance can be turned on and off from several feet away using an IR remote. The device is Arduino-controlled and has a LCD display to provide a menu based interface to the user for its operation and settings.

With its easy to use Java application compatible on Windows, Mac and Linux you can choose amongst a wide range of updates and alerts with huge customization. Noteu being Open Source, based on the Ardunio platform, interfaceable with Java API’s and a simple serial protocol allows for infinite hacking.

Solar microinverter

This application note describes a DC-to-AC converter design, specifically targeted at converting highly variable energy from a solar panel into a form that can be directly connected to the power grid. This emphasizes on the control design and how PSoC 5LP is employed for a particular power topology.

Self-organizing Kilobots

The Self-organizing Systems Research Group at Harvard has created a “thousand robot swarm“, named Kilobots, which can self-arrange themselves into shapes and patterns. Each robot in the group moves uses two vibrating motors to move and an infrared TX/RX pair to communicate with its neighbors and to measure their proximity. The Kilobot robot software and hardware design  are available open-source for non-commercial use.

Handsfree video recording goggles

Hans de Bruin’s DIY handsfree goggles allows you to record HD video of what you are seeing while having both hands free. He is using big safety goggles as the framework. He has removed the glasses and 3D printed an adapter that fits into the goggles frame and holds a video camera. He also uses a biconvex optical lens between his eye and the camera to enlarge the view of the LCD screen so that he could have a better view of what he is filming.
