I haven't noticed any trouble with belt slippage, but it's good to know 
this may be a problem (and moreover that there is an excellent solution 
available.)

This is great stuff. Do you know off-hand if these devices are stable 
over time? i.e. four hours, eight, twenty-four? I suspect good 
temperature control may improve time-lapse recording somewhat...

By all means! That's what the wiki is there for, after all.

Thanks for sharing!
