Description
this is a simple diy kit about the solar beam robotic,it has 7 micro silicon photocell,each one can provide about 0.5v voltage and 3ma current,they are so weak to drive anything,so we design a Circuit called \"Solar Engine\",In simple terms, using a voltage trigger, and a capacitor to storage to power,when the voltage tigger detecte the singal,will open the switch,so the motor or the LEds will work................
