I wanted to get a lot of the circuit boards done before carrying a rusty abandoned shopping cart back to my apartment. The landlord already think I’m a crazy person. I don’t think she would fully understand if I said “It’s for an art project, I just need to finish building circuit boards for it”.
It was a dark blue shopping cart, so before installing the LED boards I decided to cover the cells with reflective aluminium tape. It will make the lights brighter.
