An small old antique NE555 oscillator without PCB built it about 30 years ago.

This is an old project built it in the poor old age, the size around the 8 pins IC NE555, so there is no PCB, I just solder all the RC and VR with 555, so it's quite small, although the pins was broken, but the function is still ok, next time, if I want to build another one then I will using some other types of VR(potentiometer).

I was used it to put on the breadboard, it's quite convenience to do the test and they given me a great help in the old time, I made two of them with different frequency for different purposes, the circuit was drawn to sharing for the users of ee forum in Taiwan and I changed the name to English, the circuit is a quite normal and easy to build it.
