This work presents the design and technical features implementation of an expansion board, used to increase reading capabilities of electrical current measurement sources. Using a single microcontroller, it uses Inter-Integrated Circuit communication (I2C) to increase the number of analog reading channels. With this expansion board, an entire electrical frame with several circuits can be read without the need of additional microcontrollers and their associate communication network, with the advantage of adding plug and play capability.

For this reason, the implementation of an Energy Management System is highly advisable. A key component of energy management is monitoring. This paper details the hardware implementation of a low cost and highly scalable energy monitoring solution based on the Raspberry Pi and Arduino platforms, and aimed at non-domestic use.

If until c. 1970, the war chariot was considered a foreign element of steppe origin in the Middle East, afterwards, the notion that it might instead be a local Middle Eastern development took precedence. However, the publishing of Sintashta 1 in 1992 gave new life to the steppe hypothesis. This, however, was met with considerable criticism.
