Economical and basic auto-feeder and ATO recommendations?

[PotatoPig]

So I need an ATO (approx 2 gallons) and an auto feeder that’ll feed a relatively small number of fish (2 clowns, 4 chromis, one tomini tang, one engineer goby, two zebra dartfish) for 3 days…

Does anyone have any recommendations for economical options?

Note: While i normally would be interested in a DIY project that’s off the cards for this one.

ATO:
Container: Target.$5
ATO: Jecod/jebao: Try to find used one: $30

Auto Feeder: Petco: $24.99. Never failed me yet

Look for JBJ ATO (old school version)....cheap....

Stupid question: How do these ATO systems work?

They all have some sort of sensor. When the sensor trips it signals the pump to run. When the sensor closes water stops flowing. Research around many options to choose from.
