Levenhuk LabZZ WTT10 Blue is a set for kids thatincludes two walkie-talkies and two binoculars. Thedevices will prove themselves useful in many games andencourage children to find new ideas for leisureactivities at the country house, in the backyard, or ata summer camp. With walkie-talkies and binoculars, thelittle spies will be able to monitor enemy movementsduring the game and send messages to headquartersremotely. The devices are child-friendly: lightweight,compact, and easy to handle. However, the walkie-talkieshave many functions that teenagers and adults will fullyappreciate.
The project is described as a \"hackable, open source, ESP32 amateur radio board with walkie-talkie functionality and data communication\". We note that this is not a software defined radio, rather it's a highly customizable software controlled radio.
ABBA also utilized the technique for songs starting with \"People Need Love\" and fully realized with songs such as \"Ring Ring\", \"Waterloo\", and \"Dancing Queen\"; prior to recording \"Ring Ring\", engineer Michael B. Tretow had read Richard Williams' book Out of His Head: The Sound of Phil Spector, which inspired him to layer multiple instrumental overdubs on the band's recordings to simulate an orchestra, becoming an integral part of ABBA's sound. Bruce Springsteen also emulated the Wall of Sound in his album Born to Run, starting with the titular song, backed by the E Street Band. The E Street Band would become famous practitioners of this method, with songs such as Ronnie Spector's cover of Billy Joel's \"Say Goodbye to Hollywood\" (itself conceived as a tribute to the Ronettes).
