Again from Building Wireless Sensor Networks, a project makes use of the Digi ConnectPort (see ConnectPort X family user guide). There are a range of devices available, but which one is best for you? How about other manufactures such as AMX Trade Site : NXR-ZGW-PRO : NetLinx® ZigBee Pro Gateway? Continue reading ZigBee ConnectPort options
Again from Building Wireless Sensor Networks, a project makes use of Pachube, to display data streamed from XBee temperature sensor nodes. Osmos/Pachube was a great little setup, until it was bought by Xively. Big business introduces cost cutting measures (Unfortunately, Xively is neither free, nor open source), such as: Continue reading Xively – No Thanks! GroveStreams – Yes Please!
Again from Building Wireless Sensor Networks, a project makes use of the PowerSwitch Tail to control a mains lamp, using a TTL signal.
However this is only designed for 120V (US).

Following on from USB-TTL interface devices on OS X, basically I am trying to run Robert Faludi’s processing code, Simple_Sensor_Network, from Building Wireless Sensor Networks. However, I have run into an incredible number of issues: Continue reading Trying to get Robert Faludi’s Simple Sensor Network to run
I purchased a number of USB-TTL devices from eBay. None of them want to play ball when plugged into my MacBook Pro. The first is a FTDI device, the others are clones:
All work fine on a Windows 7 PC, but Macs are always quite touchy with the clones. FTDI drivers are available, and as of OSX 10.9, Apple include the FTDI drivers, so the FT232RL device should (in theory) be recognised. The other drivers offer varying success rates, for example CH340G. The CP2102 and PL2303 are physically very similar devices. Continue reading USB-TTL interface devices on OS X
Looking at the prices of various breadboards.

Finally, after moving back to BKK, I get some time and peace and quiet to build my octopod robot.
