The Tech Junkies Episode #7.5 – Maker Faire Detroit 2011

In this shorter half-episode, we recap some of the cool things featured at Maker Faire Detroit 2011 and a bit more video of the Mantis robot driving around.


The Tech Junkies Episode #7 – Open Source Robots

In this episode we show how to build your own open source robot control system using IPGamepad and other open source software we’ve written. Make sure to visit the project page at ipgamepad.googlecode.com. We also show off our latest robot called Mantis. By building the controls around a Netduino, the robot is extremely extensible and can receive commands from any WiFi enabled device.

A project write-up is on the way and should be hitting the site in the next few days. Until then, check out the Google Code page for all the details of the control system.


The Tech Junkies Episode #6 – OpenWRT Jukebox

In this episode of The Tech Junkies, Ben and Eric show how to hack an Asus WL-520gu wireless router into a music playback device. By loading the OpenWRT firmware onto the router and adding a USB sound card, it is possible to convert this cheap/powerful router into a streaming box to be placed anywhere your WiFi is in range. Now you can build your own shoutcast/icecast receiver for cheap and get music wirelessly to any room in your home.
