Hi Edgar, thanks for the details and thanks for sharing. I'll look
forward to seeing the details/files on the wiki.<br>
Great stuff!<br>

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.)<br>

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...<br>

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