[Music] At The Mouth of Mangaia - Bionicle inspired music track & video
heyitsdisty posted a topic in LEGO Action Figures
Made for the collab album Tales of the Amaja: https://bioniclefanmusicteam.bandcamp.com/album/tales-of-the-amaja Fun fact: the syncopated sample near the end of the song (where Panrahk and Vorahk appear at the end of the video) is a chopped-up vocal sample from the Bionicle promo CDs. -
Convert Audio Output into LPF RC Protocol Infrared Signal
TechnicRobot posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Recently of my experiment how normal audio output signal convert into LEGO Power Functions RC Protocol infrared signal. My audio command files are specially composed to meet the LPF RC Protocol Combo direct, Combo PWM and Single output mode. Any MP3 music player with audio socket can act as LEGO Power Functions 8885 IR Remote Control (6034989) and 8879 IR Speed Remote Control (6019910) to send LPF RC Protocol infrared signal. The demonstration used mobile phone to remote control LEGO Power Functions Motor and Servo Motor forward, backward and PWM in 7 steps. The basic circuit used 2N3904 NPN transistor to convert MP3 audio output signal into LEGO Power Functions RC infrared signal, to control LEGO Power Functions Motor. The basic circuit simple but requires higher power to drive. The advanced circuit used LM393 comparator and 2N2907 PNP transistor to convert MP3 audio output signal into LEGO Power Functions RC infrared signal, to control LEGO Power Functions Motor. The advanced circuit complex than simple circuit but requires less power to drive. My LPF RC Audio Command Files Download: https://drive.google...dit?usp=sharing- 6 replies
