The interval timer is finished. The use of an LCD makes it so much more user friendly. The length of the exposures can be selected and then each frame has a seconds timer to let you know how far it has got. The left hand button does most of the controlling at the moment. The right hand button alows individual frames to be taken without using the timer. Middle button for future expansion. Now I know what you will say - replaced the hacked Canon IR remote with an IR signal from the picaxe!
