Just prior to the lockdown, I liberated the cardboard container for a Lego Ninjago arcade kit from one of the grandchildren. The cardboard screen is pretty much the same size as a 3.5inch hdmi touch screen which in turn is the same size as a Pi3C. I reinforced the insides of the cardboard with foam board, and it all fits quite neatly into it. When the speaker arrives the next task will be to set up some battery power and load it with RetroPie before handing it back to the Grandson.
I find it quite frustrating that now it takes me a day to write 50 lines of code, that in the past would have been done in an hour or less, so while the modelling will be quick the critical path bit will be the interface coding!
