  Fireball light curves can give insight into the meteor ablation process which
can be used to improve fireball trajectory and mass modelling. To this aim, the
Desert Fireball Network (DFN) is developing a low cost add-on fireball
radiometer to supplement existing observatories. The objective is to collect
radiometric data on fireballs across a wide spectral range at 1000 samples per
second with sensitivity to a large dynamic range (mV $\in$[-4, -20]), whilst
maintaining a low cost. Here we discuss the current prototype design and first
light results.
