low power mode and temp variation

Set-up another 19 node network of Micaz motes with 6 mts310 sensor boards and 13 mts300 sensor boards. Running mts310CB code in low power mode. I initially sat all the motes together (image above) to see how close the various sensor readings were, a crude callibration test. The graph below shows that for the first […]

Fluidforms – punch bag design

A great example of how people are using Arduino as an input conduit to design product…. uses a home made pressure sensor (conductive wire grids separated by foam) around a punch bag as the input device, the ouptut is a 3D model of the object to be made. Great video, love the soundtrack.

Arduino workshop at Artificialtourism

Just back from 2 days with Artificialtourism getting some hands on experience with Arduino. After a morning of intros to Arduino, basic does and don’ts and looking at sensors available we got onto building some prototypes. First up was using a tri colour LED (see Farnell) with a simple cross fade app (from examples in […]

Perpetuum vibration energy harvester

“Perpetuum’s vibration energy-harvesting microgenerator is an enabling technology that makes wireless, battery-free sensors a reality.” Forwarded by a colleague at Arup – Paul Fuller – good to see that a UK product is pitching for the holy grail of energy harvester for wireless sensor networks.

Anisotropy – Polarization

Came across this nice image of toughened glass viewed through polarised glasses on wikipedia under their polarisation entry. I had been looking up info on Anisotropy for an image analysis project I am doing at Arup. Have been implementing some basic algorithms in processing using co-occurance matrices and simple thresholding functions… might provide a low […]
