hi ive found a circuit that i want to ask some advice on its an automatic curtain closer, it says it has automatic mode but i have noticed that it has a 555 timer. i was under the impression that a 555 timer could only do a few minutes at max.
heres the link
1. my question is it possible to change the 555 to make it a 12 hour timer?
2. could i adapt the circuit to 6v input with a small 6v solar panel to recharge the battery?
