Impulse power block with a 8-channel voltmeter

The task is to develop a low-gabarite pulse power block (IBP) for laboratory needs with 8-channel voltage and current control by a microcontroller system.
The IPP is performed on the TL494 SHIM controller with maximum load flow of 2A and overload protection. Maximum output voltage is 35V.
2 regulated channels ( 0-35V and 0-16V) and four unregulated on all standard power voltage ( 3V, 5V, 9V, 12V)
As a volt ampermeter, the ATMega8 controller is used. For visualization, a display from the cell phone was used.
