Quote: The time delay is really easy,that's a circuit called a "one-shot". It can easily be built with a 555 timer and just a couple resistors and capacitors. Light dependent resistors might be a good way to go as a light sensor, or a photo transistor, or even the solar panel if a person...

btw, regarding reversing the drill,I just realized, if we're using a flip flop we could probably dispense with relays altogether and just use a couple transistors to switch the drill direction. Just hook a beefy enough transistor or FET up to the output of the flip flop and use them as the...

Quote: I used to get a lot more enjoyment out of electronics when I did it as a hobby, funny thing that. When it's your bread and butter you want to get away from it in your spare time. I'll be doing more electronic tinkering when I move home though, and might do some in the mean time til...

Quote: THe motorcycle battery is a good idea, don't get me wrong! Might be like swatting flies with an expensive hammer though. When I design and build my system that might be what I do, since I want to do some other stuff besides just open and close a door. I've thought about a small...

Quote: Just opening and closing a drawbridge door each day, and powering some timing circuits, would be a pretty modest power drain. I don't think we'd even need a motorcycle battery to do it. Some rechargeable C or D cells might even work... but with the cordless drill you don't even need...

Hiya Peepthis541, Glad to join in on the discussion. Like I said, I've been tossing around ideas for something like this in my head anyway, so I thought I'd throw out some ideas. Until I'm moved and we're building the coop (at mom and dad's place actually) they're all just ideas. They don't...

Howdy, I'm still pretty new here, and have a lot to learn about chickens. I know a fair bit about electronics though, so this might actually be one thread I can help with! We'll have chickens after we move to IL/MO next May, and I've been thinking of a very similar idea as part of an...
