Hi there, what was the model number of the transistor you used?

Hi there, what was the model number of the transistor you used?

hello, have you made pieces for your fish? castles or houses, since I've seen people using pla and another petg or ceramic, which would be better of all?

I will try with this design for a month with a cold water fish, if it dies or if it does not affect it at all

Thanks in advance

PET - G is best - it is fully chemically neutral and doesnt affect water quality.

Thank you for this design . Printed in PLA 0.3 layer everything fit flawlessly :) Could you add bottom bracket to fit 6mm glass?

Best Regards

Here you go. (i take there 7mm hole - so it means it will have 0,5mm gap on each side which is ok and allow you to smoothly manipulate with it).

Just please send me photos of finished product.

Is it possible to set say 3 of these up and trigger them to all to feed via one arduino nano? Would be interestingto try it on my aquarium rack.

Hi, everything is possible. :)
Insted of one servo you can use 3 and feeder boxes will be conected with wires (powersource and driving signal)

If you need more help let me know.

I am preparing more advanced version with display possobility of manual run of feeding and also there will be something like vibration motor which help avoid stucking fo granules.

Really good stuff!
Can you give more details on the arduino program please?

Yes you are very fast :) I am preparing complete instrctables .... :)
