Video Downlink
A Pixera mini camera ($26) will take video.  It feeds into a Decade Engineering BOB-II video overlay module ($85)
that accepts commands via a serial line.  The output of that feeds into a Comtech 100mW 2.4Ghz PLL controlled RF
module ($45). The RF module is controlled by a PIC ($12) that selects the frequency based on dip-switch settings.
The RF module feeds directly into a dipole antenna, built from plans found on the internet.
A commercial X-10 2.4 GHz receiver ($25) will be
used to down-convert the video signal for display on
a standard television.  I will use a omnidirectional
collinear vertical stacked dipole antenna built from
plans found on the internet.
