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

Last crawled date: 3 years ago

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:

TR8x8 500mm trapezoidal screw


Pololu 1124 motor with angular gear


Two 18650 cells


LM2596S ADJ voltage regulator (i set voltage to about 6.2V)


Relay module KY-019 ARDUINO - 2 x pieces


Switch T105 / 55 bistable


Arduino MP3 player module with microsd card and 4ohm 3W speaker


6 x blinking LEDs


Endstops x 2

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).
