Hot Chicken

It prevents water from freezing

Hi there, I made a simple project a little while ago. It didn't work just yet but it is now.

For some reason I ended up with a chicken and temperatures that dropped to -18 at night. Long story. It took the drinking water less then an hour to freeze and since there isn't someone arround all the time I had to help the poor beast. At least next year that is :)

I started out with this thing:


It's basically a relay switchable by picaxe, a 12v to 5v voltage regulator (take the right one, I screwed up in a silly way here, thanks Geir). It also has a diode (front corner) which alows me to hook up solar panels and charge the battery). In addition I got these of ebay "Motorcycle Heated Grip Pads for Handlebars" (6$)



I stuck the above to a regular drinking bottle for birds (they have glue on 1 side, easy does it) and then covered the bottle with isolation foil. All together it looks like this:


Motor heaters

It draws about 900mili amps and the relay can handle 1 amp (at a higher voltage). Then there goes a thermometer (LM35DZ) to the bottom of the bottle again isolated. I stuck this right to the bottom and hotglued it tightly to make sure i get the water temperature and not the outside temp.


Bottom with sensor

And all together it looks something like this:


Ready to go

So there you go, the picaxe measures the water temp, if it gets below 3 degrees it turns on the heater if it gets above it turns off the heater. It has a 12v battery from an old UPS that's being charged by the solarcells.


Assembled with batt

What I would improve next year is adding an LDR so it knows when it's dark. Chickens are off to bed when the sun goes down so that would save the battery (I just guess, maybe it will take more power to heat up a block off ice in the morning).

Be good to your chicken, you might need it for your next "tracking" project;

I never knew you where also into chicks!

C ya one day, dude ;) One day!

Thanks for sharing, and letting me know that you are still out there, inventing and alive :)

Yo Dude! Finally things are clearing up a bit with little other work that's left to do. LMR time :) I got the giant shell in we spoke about a while ago. My wife managed to turn that into a very small shell. Lot's of them. So no exo skeleton robot to come as I don't want to spent another 100 bucks on a clamp :)

Still my friend is working on a frame, soon to be ready, and I'm freaking out over schematics and scribbly things that actually translate into components so I can finish some projects like the mini reef.

You should get over to Eindhoven for the robotics world champion ship man! Free accomodation and booze, bring TH :)))

I got the chicken from a friend who couldn't take care of it anymore and since my daughter was nagging over a dog, hey.....


It's not gonna happen - not this time, though thanks. But maybe we should agree to hook up when we retire, and all birds has left. You are going to be so fat and done, and I will be vital and fresh. So I can get you beer! TH will have re-emerged as a homemade CNC-styled paranormal version of himself! I will hack both of your personal robots, and they will make naughty moves as the sun sets, and you roll a :j

I don't know what you took but I want some!

That's not a robot chicken, is it?

Seriously.  The picture of your daughter holding it reminded me of something I saw on the web somewhere, where some guy tried to use a chicken as some sort of sensor (or something) because of the way their eyes lock onto things.

I'm not kidding.  I'll try to find it.

It was a steadicam.
