Automatic door opening system
Posted: Sun Apr 03, 2016 5:47 pm
I'm starting to think about making an automatic door opening system for the polytunnel.
I'm wondering if I can re-purpose a greenhouse vent opener such as this: http://www.amazon.co.uk/Gardman-Greenho ... o_pC_S_ttl
What's not clear to me, is if the vent opener relies on having the weight of the window for it to work. If this is the case, then I guess it would not work.
I'd be interested to know if anyone has tried something like this before / or has any alternative ideas......
Thanks
