The first version of the Scrobble Box consists of a Raspberry Pi Pico W powered by USB and a light switch. When I flip the switch on, my program finds the most recently played track from KXLU's Spinitron page and scrobbles it to my last.fm account. This continues in a loop and scrobbles all the tracks that are posted to the KXLU Spinitron page, until the switch is flipped off, in which case it stops scrobbling.
