Nothing goes flat quicker than batteries whether it is playing Nintendo Game Boy or listening to a Walkman. When getting into electronics batteries soon become too expensive to use on a regular basis. What is needed is a power supply which can be connected to the mains electrical supply of your house and which can provide the range of DC voltages that are required for basic electronic projects.
This kit is designed to fill this need. The circuit is basic but it will satisfy the requirements of most electronic kit users especially when starting out. Two DC voltage outputs are available. One is a fixed regulated 5V for TTL use. The other output is variable from 5V upwards. The maximum output voltage depends on the input voltage. The specified maximum input DC voltage to the regulator is 16V. The minimum input voltage must be 2V higher than the regulated output voltage.
All components are through-hole and can be easily to be soldered to the PCB.
