Little Ghost Heart

This is my Little Ghost Heart. It is just an demonstration of four different methods to generate light and heat:
1. A LED under the magic eye tube (red).
2. A neon bulb (green).
3. Heat coil from the tube (orange).
4. The two pixel display of the magic eye tube (pale green).
Combined with a NE555 for the "pulse" of the heart. The high voltage is generated by a flyback converter out of 5V.
