Eneloops would only last about 3 weeks. And disposable last 2 months. This door is used a lot and since it has Zwave and a door open sensor it sends info on every open.

Bonus, since it can handle the lipo AA batteries that put out 1.8v and it gives the motor more oomph I made the battery pack give 7.2v and it never sticks anymore.

This is a garage-door so its not critical access but is used a lot.

This did make me realize I've never seen a deadbolt reversed. As in the door having just a metal framed hole, and the bolt come out of the frame. Seems like the easiest way you would be able to run power to it. (Maybe not the most structurally sound, probably depends on the door material)

I don't know. I think that if you built the receptacle right, It could probably work pretty well... Most deadbolts are pretty shit in general (rare to see people reinforce the jamb), so, even an naive attempt probably wouldn't be that much worse. For a metal door with a chunky insert, I think it would work fine. For any other kind of door, I think you'd probably need at least a frame or large plate to distribute the loads, but it's still probably wouldn't be much worse than a conventional configuration. Huh...

I guess the main complexity (or just oddity) would be the keyhole wouldn't be on the door.

Why did you mount two hydraulic pistons with holes drilled through the door frame to have double deadbolts going into a solid wood door with metal framed slots? Because I was bored and wanted to make hole in the wall and overcomplicate something that can be bypassed by opening the windows I leave open 5 feet away. Lol

Yeah, I guess I'll add that to the reasons I could never be rich.. id do way to many stupid things for my own amusement.

Doors are largely designed to a standard thickness; walls are not. Deadbolts have to attach through the thickness of the material they're mounted to.

That can't be it. We have vents that needs screws on both sides and go through walls just fine. Maybe it's regulatory instead.

This is how electronic locks work in prisons and jails. Motor in the doorframe with a bolt, power on to unlock, fails secure in the event of a power outage.

In an event of a fire that sounds quite uncomfortable. On the other hand my knowledge about prisons isn't very profound.

I guess if you had french doors and opened the "wrong" door, it would be similar to a reversed deadbolt.
