We present results from high speed photometry of a further thirteen faint cataclysmic variables .
V356 Aql ( Nova Aql 1936 ) shows flare-like outbursts with recurrence time scales \sim 3000 s , but no coherent periodicities .
Aqr1 is an intermediate polar with a spin period of 6.7284 min and a probable orbital period P _ { orb } = 3.226 h derived from orbital sidebands .
Its orbital sideband frequencies show very variable amplitudes .
The published spectroscopic period of 2.0 h suggests that Aqr1 is similar to GW Lib and FS Aur in having an additional periodicity of unknown origin .
FIRST J1023+0038 has P _ { orb } = 4.7548 h with an orbital modulation of range 0.45 mag , probably caused by reflection effect from a hot white dwarf primary ; as such it may have been a nova sometime in the past few decades .
H \alpha 0242 is a deeply eclipsing very low mass-transfer rate system , probably a dwarf nova of very long outburst interval , with P _ { orb } = 1.792 h. GI Mon , an old nova , has optical modulations at 4.325 h and possibly also at 48.6 min and is thus a candidate intermediate polar .
AO Oct , an SU UMa type dwarf nova , shows orbital modulation at quiescence with P _ { orb } = 94.097 min .
V972 Oph ( Nova Ophiuchi 1957 ) showed no flickering activity during one set of observations , but did so at a later time , confirming the correctness of the identification of this object , but it shows no orbital modulation .
SDSS 0155 is a deeply eclipsing polar with an orbital period of 87.13 min .
SDSS 0233 shows flaring activity but no discernible periodicity .
No periodicity was found in the new AM CVn candidate SDSS 1240 .
SDSS 1556 shows a periodic modulation at 1.778 h which is possibly due to orbital motion .
SDSS 2050 is an eclipsing polar with P _ { orb } = 1.5702 h. FH Ser ( Nova Serpentis 1970 ) has strong flickering activity but no detectable orbital modulation .
