Brian Jepson talking about hacking the real world
He's talking about the Make Controller Kit and Arduino boards, and despite being from Make: he's focusing on the Arduino boards because it's "super open". The main difference is that the Arduino doesn't have an operating system, unlike the Make: board, and it's "...a lot like the old days".
Update: He's talking about the different types of 'serial', and just mentioned the MAX232 chip which does conversion between RS-232 and TTL serial.
Update: He's talking about the Parallax RFID module which is a great module, cheap, and the pins plug right into a breadboard.
Update: This is pretty cool, he's pushing through some code examples of how to use the Parallax RFID module with the Arduino board, which apparently come from Making Things Talk (via amazon.com) by Tom Igoe.
Update: He's talking about a bunch of different sensors, including the pretty interesting volatile organic compounds sensor from FigaroSensor.com. Also interesting is force sensing resistors from Trossen Robotics.
Update: He's also talking about a Serial to Wi-Fi widget, with a simple telenet level interface, about US$90 from SemiConductorsStore.com.
Update: There is also a GSM module, with embedded Python, for US$150 from SparkFun.com, and a GPS module for US$70 from Parallax.com.
Update: Apparently Brad was sitting somewhere in the back.
