If you have a hard time keeping your remote from getting lost, DIYer Colin shows us how to put together an IR blaster that lets you control your TV and cable box from a web page.
Colin, who lives in a fraternity house that often misplaces the remote, built this out of an Arduino UNO, an Arduino ethernet shield, and an infrared receiver. Essentially, you can control the TV's channel from the the box below the TV, which sends remote signals to the cable box above it. If you don't want to get up, you can also access a web page from any device connected to the network and change the channel, whether it's a laptop, tablet, smartphone or anything else with a web browser.
