I'd love to have blackout blinds that close every night and open 30 minutes before my alarm goes off. I haven't been able to find a quality (quiet!) product that does this.
Someone else mentioned the ikea shades coming out in October, so I might wait and see how those are. Potentially much cheaper, but no slatted blind effect, so the only option would be to fully raise/lower them (and deal with whatever noise that generates).
Opening blinds is generally a morning thing, and ideally would want to be the quiet option if you could only have one option which was quiet (theoretically speaking). What if the electric motor drove the blinds down by pulling a counter weight. That way in the morning to open the blinds it would only need to release the weight, which wouldn't require any substantial movement and therefore limit noise...?
Yeah I'm bored at work.
We may be on to something here...
I'd also like exterior blinds that can be lowered to reflect away or otherwise counter the effects of direct sun in summer.
You might be able to hire someone at a local makerspace to build something along those lines.
