90 ton 1/14 metal excavator scratch build w/embedded PC

[SteinHDan]

Test digging gravel and also testing the audio and the smoke generator. The engine sound will be replaced with an excavator sound and both the sound and the smoke will be made to adjust according to the power output of the machine when it's working.

The smoke generator was the surprise that I promised earlier :-)

It works quite well as you can see on the video above. I mounted it so that the output is at the same location as the exhaust on the original CAT 390 F.

I have the 12V, "standard NON ESC" version with red color. I control the variable output with the first channel on the fourth motor controller.
