Dan’s incredibly complex invention works by making use of relatively simple quantum tunneling concepts. At the core of the invention is a small piezoelectric buzzer that can be bought for under a dollar.
The piezo buzzer is used in conjunction with a tungsten needle to form the scan head. The needle measures voltage changes over the subject being scanned to reproduce a magnified image pixel by pixel. The whole apparatus is suspended in the air by magnetic levitation to reduce the effect of ground vibrations.
Here are some example schematics of Dan’s misropscope build:
