Besides having pitiful programming skills my two major problems are power and storage. For storage I built a 16x12 shed this year, but for power I use mostly LEDs. I've put up all the lights on the front of the house - see photo - and the "measured" power usage for all this is 1.46 amps and that is with all on, so for blinky it is even less. There are 72 LED strings lit up here.
I don't put up anything in the yard until the week of thanksgiving. Still have to put up lights on the roof peak, also all led. By contrast my 16 incan mini trees take over 20 amps. I'm hoping I can afford some Smart strings for the house and then make new led minis from what is on the house now.
