Automatic fish feeder for aquarium.
I made this feeder in to our nano reef aquarium.
I have a Siemens Logo! which drivers the motor in the feeder.
The holes are made for small pellets (1.5mm x 1.5mm) which many times got
stuck in our Rondomatic feeder due the moisture.
Now all of the pellets have gone in to the tank without any problems.
The glass thickness in the tank is 6mm.
The motor used is a DealExtreme SKU: 214121
There is also a fitting for a ball bearing in the lid, but I did not use any bearings.
I used a 3mm drill to clear the holes for the bolts.
There is a need for heating when assembling the motor Axel and the nuts.
That is because I wanted to make a very tight fit.
