It is a stabilized power supply on system LM317. The device uses home made voltmeter on ICL7107. Also power supply on LM7805 can be made for the device. All boards were made in thermal transfer method. The main advantage of the project is its low cost – many elements can be removed from disassembled old machines.

230V fuse was applied at the input and all the paths were protected with rosin and alcohol solution.
