It just popped to my mind that perhaps I could get some help here on how to create one of these. Though it must be pretty simple, just an amateur here. Any help highly appreciated. Thanks.

In one of the hobby electronics shop over here, ready-to-stick PCBs for musical cards are available. Buy the one you like & stick it. Thats it!
The PCB has single COB (Chip on Board) which is very thin and it is difficult to build such PCBs at home using standard DIP ICs.

Check the shop nearest to you and see if you can find one.
