So I installed a fire-protecion-approved door drive that is hooked to a raspberry pi. Another raspberry pi then analyzes a video stream and detects my cat. If my cat is in the frame for n amount of time, a message is sent to the pi conntected to the door drive and the door opens up slightly for him to get in.
A cat door that can tell if the cat has a mouse it's going to "gift" to you, and locks to keep the cat out.
I loved reading what you are doing with the Pi though.
Since last week I'm in contact with the manufacturer of the door drive tough because they maybe want to create a product out of it. To be honest I think it would pure marketing and at the moment it is very unlikely to ever hit the market.
Unless your cat door goes to market. May luck be on your side :)
(really, don't underestimate niches, you can probably find plenty of places to sell this sort of product...)
Maybe a bit off-topic but: The only thing that differs an "fire-protection approved" door drive from a non approved drive is that the drive is not allowed to have an option to keep the door open. Also in case of power outage (or fire) the door needs to close without power.
I will open source everything once I'm happy with the security and the ability to configure it.
Reads like a monty python sketch.
