Centrifugal fish autofeeder
This easy as well as cheap but effective deve is mainly intended for your ease to leave your fish autofed. You need no longer worry your fish would starve as this autofeeder would replace your job. This autofeeder device will expell pellets by quantity as well as time intervals as you like. Besides, making this circuit seems to be a bit entertaining as you are insisted to make it yourself and so It would develop your creativity. Don’t worry, it works!
This device comprises of 2 sections, electronics and mechanics:
Electronics Section
The main role of this section functions as a timer (few hour intervals) with progress indicator and the mutual action of the relay and capasitor functioning as expelled quantity of pellets.
Working System:
The circuit is using regular timer (IC 555) sending pulse to 2 cascaded counters of CMOS 4017. The output pin from the last counter is then fed to the capacitor and-relay in series. (Remember: a relay owns its own resistance) which consequently trigger the relay for some time to turn height=582 src="/data/attachment/portal/201007/ET36891201007240312412.jpg" width=655 border=0>
