A handful of electronics I've edited into 32x32 sprites.

electronics_full_sheet.png, handheld_game_sheet.png, misc_electronics_sheet.png, and usb_stick_sheet.png each have 0px padding.

misc_electronics_32x32.zip contains the sprites as individual files.

handheld_game_32x32.zip contain the sprites as individual files as well as Paint.net (.pdn) files with all the color and screen variations on their own layers.

usb_stick_a_32x32.zip contain the four color sprites as individual files as well as Paint.net (.pdn) files with all the color variations on their own layers. 

usb_stick_b_32x32.zip contain the three non-color sprites as individual files as well as Paint.net (.pdn) files with all the color variations on their own layers.
