I worked out it costs apx 4 to 6 cents per hour to run a DMD pinball machine. Thank fark for that at least.
(I have a smart meter that gives me the cost of every appliance in the house in real time as I turn it off and on and gives perfect costing accuracy).
I note, 4 cents per hour is with the machine just turned on in attract mode, and 6 cents per hour with the game being played. These figures are the same over apx 30 different DMD machines. So overall, the pinball designers did a good job designing these games to save electricity use and costs whilst being placed on-site.
If ya electricity bill is high and the wife blames the pinball machines for the big bill $, you can now defend yourself and your pinball machines knowing the price per hour to run them is bugger all.
* tips to save money, set ya washing machine/dishwasher etc to start at midnight etc, when everyone is in bed and it will use offpeak rates etc , depending on what plan/electricity company u are using. The way bills were calculated say 5 years ago, are completely different to how these companies do it today. It used to be only hot water had a peak n offpeak cost, but not anymore. They now stiff you on all usages. It pays bigtime $ to study your bill and your supplier, and to really shop around.
