Simple 555 charge-pump circuit to create a negative tracking split supply voltage that mirrors the single supply input voltage.
It was an implementation of this design: http://www.syscompdesign.com/Negative-Tracking-Power-Supply_b_89.html for testing.
NOTE: This circuit isn’t stable and will generally go up-in-smoke. I advise forgetting this one and use the LM2662 based circuit instead, which works well.
