Looks about right on blue and red, not sure why you aren't getting it on the
green too. Could be a duff transistor on the green channel (just thinking
out loud here!)

You've got an awful lot of ghosting on your video output, which will make
the picture less clear especially with the subtle changes by the
Kaleidoscope. If you are feeling adventurous with a soldering iron - replace
the inductor marked as L5 on the SAM motherboard with a wire link (or just
solder a wire link across it)

Yes.... useless isn't it? :)
