This is me etching tungsten wire with 2M NaOH, a steel plate, 333-ohm resistance, and 24V ...

This is a test of nearly all of the STM circuitry - unfortunately I don't have the op-amp gains set properly so the sound from the scanning head is...

This is an arduino controlling a pair of 10bit DACs (the chips are MCP4911s) via serial control (using the SPI protocol).

This is a required step ...
