This is a small ajustable clock based on microcontroller PIC16F84A microchip.The electronic project here is very simple because the hardware only uses 74hct238 demultiplexer, 4×7 segments, and some resistors. The software is programmed through a device connected to serial port with icprog and made/debuged with MPlab. For PIC Programmer you can use JDM PIC16F84A programmer.
