LM317T Voltage Regulator with Pass Transistor

electrionic dice, made on a pcb. Shortly described it consists of 9v battery, the TS7805 Voltage regulator, the ne555 astable multivibrator to produce a clock signal, a Xilinx XC9572 CPLD (Complex programmable logic device), 7 diodes, a push button, and a couple of capacitors and resistors. The CPLD is programmed with VHDL from Xilinx ISE.
