Hey James,Here is all of the information that I can offer you on the PCB that we're trying to develop. It'll be a single sided board that is able to scan a barcode and unlock a recycling bin through solenoids. Everything is run by batteries that are solar charged. The computer should store scanned barcodes, have an internal library of valid barcodes, and be able to download used barcodes and upload new barcodes via a USB.A BOM and circuit diagram are attached. We're open to any changes that you see as necessary, just please note what the changes are and get my approval first.Cheers,Evan UdelsmanDesigner Show More
