	A design of a new power supply controller was initiated in BINP for upgrade of existing accelerator facilities and for demands of future projects. Any accelerator facility includes a set of diverse power supplies which controllers have different specifications: number and precision of DAC/ADC channels, speed and algorithm of operation. Therefore, the main idea is to elaborate a controller, which consists of common digital part including an interface with a control system and specialized analog frontend that fits to power supplies requirements. The digital part provides easy integration to control system by means of some standard network protocol and performing some data processing and analysis. Ethernet is used for communication with controllers, MQTT is under consideration as a high-level transport protocol in some cases and EPICS IOC was tested to be embedded into controller. The initial prototype of controller is developed and deployed at VEPP-3 storage ring. The status of the work and future plans are presented in the paper.

	Modern electron beam machines for different applications including welding, additive technologies and etc. consist of many different subsystems, which should be controlled and monitored. They could be divided by so-called fast and slow subsystems. Slow subsystems allow reaction time to be around couple of seconds that can be implemented using PC. Fast subsystems require time to be around hundreds of microseconds combined with flexible logic. We present an implementation of such fast system for mechanical moving platform and electron beam control. The core of this system is single board computer Raspberry Pi. We employed a technique of fast waveform generation using Raspberry Pi on-chip DMA to manipulate stepper motors. Raspberry Pi was equipped by external CAN controller to operate an electron beam via CAN DACs. Special software was developed including libraries for low- and high-level technical process control written in C and Rust; and in-browser graphical user interface over HTTP and WebSockets. Finally, we assembled our hardware inside standard 19-inch rack mount chassis and integrated our system inside experimental electron beam machine infrastructure.
