View Full Version : Does anyone auto feed? plc controled

I have been thinking about it but nothing seems like a real good idea.

I built a silly little carousel feeder driven by a hobby servo... Was very easy to have the parts milled from plexi on a CNC. (I've had more recent projects cut with a laser, but this one had to be built in a day when I had to leave the country for two weeks...)

Currently controlled by an ATmega 328 (running arduino firmware for the time being)...
I've been thinking about revising the design a bit and perhaps switching to an ATtiny in the process... (Removing the feeding from the rest of the control for the tank... essentially having it just be serial triggered on its own)

I have two methods of controlling feeding. One style (which I've been running mostly) involves a serial trigger from a cron job running on a SheevaPlug embeded linux box, but another uses a RTC mounted with the PLC.

I'd be happy to share any insights if you got any particular questions... I think the physical design of mine is lacking, but has worked fine for the most part for dry food for about a year and a half.

enigma32, do you have any pics of your feeder?
