So, I have an idea on how to build a frozen food feeder. I'd like to get some feedback...
As you can see from the picture, I've placed a rubber stopper in a 250ml beaker. There is a long glass tube that goes through the stopper. It comes within 1/4 inch of the bottom of the beaker and sticks out above the beaker about 2 inches. The second, flexible tube goes through the stopper and comes out just past the stopper on the inside.
Connected to the long flexible tube will be an air pump. The pump will be controller by this timer:
I've chosen this timer because it allows you to control power down to the minute.
The idea is this: Have the timer switch on the air pump going into the beaker. As pressure builds up, it will force the food up the glass tube, into another tube going into the tank.
But I have some questions:
1. Will the time the air pump needs to run increase as the level of food decreases?
2. Will the stopper hold enough pressure inside the beaker to get food into the tank before it pops off?
I'm thinking a regulator will be necessary with a pressurized air tank. Also I chose to use this beaker because it is what I have on hand. I suppose a container with a screw top would be a better choice. As far as keeping the food cold, I thought I'd set this contraption up in a small, table top refrigerator and just have the tubes run in and out.
Thoughts?
