$5 auto chicken door

[cchristal]

I have made on of the automatic chicken doors fond here https://www.backyardchickens.com/t/...-5-bucks-with-a-radio-antenna-from-a-junkyard
I used two 12v 1.5 amp plugs for the power source and but the door on ball bearing cabinet gliders. the door opens and closes but only partially some times. does anyone have any suggestions to make this set up more reliable so that it would open and close all the way every time? would the antenna motor be more powerful it i used power converters with higher amps? should i not use the drawer ball bearing sliders to attach the door? please help

 

[Why Did The Chicken Cross]

The linked instructions on that thread used 5amp power supplies so it sounds as if you don't have enough juice. Or a defective antennae.

Is the door heavy? Will the antennae move all the way up and down when not attached to the door?

Do you have a multimeter and can measure the current when it is going up?

The door is not teribly heavy. It is 14x28 plywood with a galvanized steel sheet on the surface facing the outside of he coop. The post I got the plans from had someone do it with a 1.2 amp converter. Will simply increasing the amps increase the power of the antenna motor? The antenna does work perfectly when not attached to the door. If the motor is running at full force then the only thing I can do is change the door assembly to have less resistance some how. Maybe by not using drawer gliders. These are the gliders that I am using http://m.homedepot.com/p/Liberty-22...nt-Drawer-Slide-1-Pair-D80622C-ZP-W/202200646

Maybe I should try these instead http://m.homedepot.com/p/Liberty-20...nt-Drawer-Slide-1-Pair-D68820C-W-TS/202200639 what do you think? And I do have a multimeter
