Why shell out hundreds or thousands of dollars on various home control systems (HCS) when you have the skills and resources to build your own? You can design and implement sophisticated Internet-enabled systems with free tools and some careful planning. … Continue reading

DIY Solar-Powered, Gas-Detecting Mobile Robot
Take a look at the complete SOPHOCLES design.
The case for the optical gas sensors, consisting of the
multicolor LED and the TSL250 in front of the robot,
has been removed to give you a better view. The
CMOS camera is placed on top of the robot, and the
radio modem is hidden behind the camera so only the
antenna is visible. A flexible cable connects the camera
with the MSP430 microcontroller.

German engineer Jens Altenburg’s solar-powered hidden observing vehicle system (SOPHECLES) is an innovative gas-detecting mobile robot. When the Texas Instruments MSP430-based mobile robot detects noxious gas, it transmits a notification alert to a PC, Altenburg explains in his article, “SOPHOCLES: … Continue reading
