  We have conducted a survey of candidate hot subdwarf stars in the southern
sky searching for fast transits, eclipses, and sinusoidal like variability in
the Evryscope light curves. The survey aims to detect transit signals from
Neptune size planets to gas-giants, and eclipses from M-dwarfs and brown
dwarfs. The other variability signals are primarily expected to be from compact
binaries and reflection effect binaries. Due to the small size of hot
subdwarfs, transit and eclipse signals are expected to last only twenty
minutes, but with large signal depths (up to completely eclipsing if the
orientation is edge on). With its 2-minute cadence and continuous observing
Evryscope is well placed to recover these fast transits and eclipses. The very
large field of view (8150 sq. deg.) is critical to obtain enough hot subdwarf
targets, despite their rarity. We identified 11,000 potential hot subdwarfs
from the 9.3M Evryscope light curves for sources brighter than mg = 15. With
our machine learning spectral classifier, we flagged high-confidence targets
and estimate the total hot subdwarfs in the survey to be 1400. The light curve
search detected three planet transit candidates, shown to have stellar
companions from followup analysis. We discovered several new compact binaries
(including two with unseen degenerate companions, and several others with
potentially rare secondaries), two eclipsing binaries with M-dwarf companions,
as well as new reflection effect binaries and others with sinusoidal like
variability. The hot subdwarf discoveries identified here are spectroscopically
confirmed and we verified the Evryscope discovery light curve with TESS light
curves when available. Four of the discoveries are in the process of being
published in separate followup papers, and we discuss the followup potential of
several of the other discoveries.
