Lego and electronics, I had to combine them at one point or another. I have been working on something a while with the two together. This is just as good.
I had a raspberry pi 2 b+ (older model ) for a while and I noticed a Wave share capacitive touch screen was half price on amazon.
I intended it for another project but it ended up here where I built a lego frame around it to house the wires and boards.
I had to install some file's on to the micro sd that came with the touch screen. Attached a mobile phone power bank that can sustain it for a few hours.
Voila a lego drive in theatre. I add a nano wifi adapter attached so you could stream from your wifi a film.
