Expansion of the Observation Tower (electric elevator, LEDs, mp3)

thingiverse

This is a remix, actually an extension of the "observation tower" - an electric elevator module with blinking LED diodes and playing music when the elevator is started :) Please print all STLs in 10% scale. My tower from the video / photos is printed at a scale of 140% of the original and is 80cm high - it's really great, congratulations and greetings to the author of the original project! :-) As soon as I find the time - I will make a BOM (if necessary, ask in the comment!), But in a nutshell, you definitely need: 1. TR8x8 500mm trapezoidal screw 2. Pololu 1124 motor with angular gear 3. Two 18650 cells 4. LM2596S ADJ voltage regulator (i set voltage to about 6.2V) 5. Relay module KY-019 ARDUINO - 2 x pieces 6. Switch T105 / 55 bistable 7. Arduino MP3 player module with microsd card and 4ohm 3W speaker 8. 6 x blinking LEDs 9. Endstops x 2 10. 0,5A polymer fuse - VERY IMPORTANT! It is easy to burn the engine without a fuse :) Some epoxy glue, m3 screws and nuts and a few meters of thin wire :) Most parts may be printed without supports (only plate for engine must have small supports).
