  • Home Automation

    There is a decent amount of home automation running at the Vondruska house. I’ve gotten quite a few inquries on everything that is running. I try to keep this updated as much as possible.

  • Wireless Automated Cat Feeder

    Here’s a cat feeder I built over the last couple of months with no useful electronics experience (touched a breadboard in high school, 5 years ago and my day job as a web developer). It uses an Arduino Uno and a DS1307 Real Time Clock to keep track of when the cats should be fed. The Arduino Uno is connected to a servo which rotates a canister to dispense the food.

    For the wireless communication I used a Xbee Series 1 to communicate to a Linux home server running Java/PHP/mySQL backend. The server bridges the connection to an Android app where my girlfriend and I can view the status of the feeder and control feeder remotely from our phones.

    I wouldn’t say its very visually appealing (yet), and there’s room for improvement. But here’s some photos/videos of the feeder in operation:
