I’ve had an idea for a Halloween project. My house has two 1m square windows separated with a small gap upstairs that would be perfect to put those Adafruit animated eyes in.
I can use a Pi and Adafruit’s HDMI code and a splitter to get two images but I’m stuck on what to connect to.
The obvious answer is two computer monitors but the only ones I have are 22" and 24" and would probably look too small in a 1mx1m window. I really don’t want to try to buy 2 large proper monitors just to make a decoration for a few hours.
Does anyone have any ideas under about £50 for this? Low res would be entirely fine. I thought maybe cheap Fresnel lenses but would those work at enlarging the monitors displays for someone in the street outside? I don’t think they work that way.
Are there really cheap little projectors that I could project onto from inside the room to get the effect maybe?
