I'm having flashbacks to the movie, Damnation Alley from 1977!


Specifically, this scene!  :o

This movie IS post-apocalypse, so yeah. Fits right into the "Fallout" theme, just from the 70s.

Cool, I just finished watching Fallout S1 on DVD last night.

And here I thought we were talking about the video games!  :o  LOL

Back on the subject of these latches. I thought of another use for them in terms of kind of a reverse logic.

Many years ago (like 35+), we used to catch squirrels and pigeons using box traps, where the critter would go under the wooden box to get a treat and you would pull the rope, removing the stick that held the box up. Gravity would drop the box and you usually caught your critter.

Once in a while the squirrels would either get hit by the box, or escape altogether. It occurred to me that you could use these latches to release a spring-loaded door that closes, rather than releasing a door to open. It might be usable in a situation where you're trying to live-catch a critter. Just a thought. What do y'all think?

That sounds viable option.

Quote from: granz on Sep 17, 2025, 07:23 AMAre you planning on putting these on your house's doors? Will this be part of your home control security system?

So, these were for testing for a customer application involving swiping an RFID tag to open a lockbox. As I started the project and testing of the locks, which I was supposed to go over with the customer, he stopped contacting me, and I don't think he's getting my email. So I am going to roll this into a new project, which I already tested, but for which I need your feedback.

Since I have four electronic latches, I decided to build a locker system with four lockers that can be remotely accessed, or via RFID Tag, Password or Smart Phone. The prototype is a wood panel with f doors, but I wanted to build an actual metal locker as a working demo. The current working title is, "Package Pick Up Smart Locker", but I was wondering if anyone had a better and / or more streamlined name.

This sounds like the kind of thing that you might have at a PSC (Postal Service Center, not quite a Post Office,) only more high tech. The PSC that I had in tech school was run by Active Duty Air Force personnel, and so was not a Post Office, but had Post Office-type boxes, and could take packages to mail out.

I like that title, it may be a bit long, but gets the idea across. It sounds like something that you would use at an Amazon pick up center to get your packages.

The Amazon lockers were what inspired this project. People think they're so high-tech, and Home Depot and other stores have similar lockers you can use for product pick up. The fact is, with relatively little hardware, you can make it so the locker can be opened via website request, Bluetooth interface from cell phone, RFID tag or type in a code on a keypad.

The current test code for password uses a (fake) order number, billing zip code and the last 4 digits of your phone number to open a locker door. I have a simple 4x20 LCD and 4x4 matrix keypad.

That sounds like it should do the job. I would even think that it would be good enough security for real-life work.

Yeah, once I have a metal cabinet, I wanted to add the code to TXT me each time a locker is accessed.

You cannot view this attachment.

I was thinking of something like this for the lockers. For the demo, I might be able to find something used locally via the FB marketplace.
