got this little guy for 20$. video feed would cut out after 4 seconds, frigged with the wires for a few hours and started poking at it with a razor blade. when i connected the ground wire to the signal wire in the video feed it worked better. officialized my hack with some aluminum foil and the machine is steady (at about 80% quality)
