Most worthy Stefan ..cool!

Hint: Cordless drill trigger connected to your gearmotor will give you speed control and direction switching.

Making the string a loop going around idler pulleys at each end will give you two directions without re-rigging.

LOVELY tank!

Sure, it's not my last wisdom and will be improved step by step.
In the moment it's more the fun to do it maximum cheap.

Last not least when i see that i will use it more often so or so i must buy a professional system,
because for photo-timelapse this motorisation isn't sensefull when the move doesn't stop for the exposure.
My next step is to proper fix the motor and battery holder, .... and a on/off switch ;)

If you wanted to make your time lapse version you could use a microcontroller like raspberry pi or arduino. Not sure how far down this rabbit hole you want to go :-)

Great work though!

My first slider was a DIY motorized one. Way to go.
