Here are some neons that I set up for aging.

This is a 555 oscillator that I built but I didn't purposefully make it look like a smiley face.

This is another picture of the 555 oscillator.

They are 14 pin sockets I had on hand. They are for wire wrapping because they have square posts. Also the leads coming from the socket are longer than the common ones.

The output freq of the oscillator can be adjusted from ~10Hz to about 21kHz.
