I've been looking for options to keep the cat busy while being away and found the interesting project of the automated cat laser

Now my last programming has been years ago and electronics is also not my specialty
But seems like just using a constant 3.3V power supply and a smart plug would not be too complicated to achieve that goal.
Which other parts would I need to achieve this and where would I hook them up? Basically, the goal would be to turn on the power supply, switch the laser on, then let it run for 15 minutes. Then switch power off and turn back on on a schedule.
Ideas would be much appreciated
