My (not for real) sister found this old yet futuristic looking gun from the depths of her bedroom. It was all trashed out, the speaker had an unsoldered wire, there wasn’t a contact for the positive side from the battery compartment and the original LED at the end of the barrel was missing. So she asked me to repair it but i decided to make it more interesting adding a couple of contact sensors (AKA wires hooked to a couple of screws) and a LDR as well as a switch to select one of them to mess around with the sounds that this old school laser gun regurgitate.
