I’m a retired engineer and I built a wave motion machine as a Christmas present for my wife. What started out as a pretty cheap project (under$100 for materials) now has turned into a mission and I’m currently well over $200… So much for cheap! Eventually I’m going to get this ac…

Hi @Dmzark and welcome to our forum :slight_smile: You have an interesting project :slight_smile: I don’t know a lot about wave machines but I would like to see yours :slight_smile: Could you maybe post here some photos or even better some videos of it? Thank you.

Hello, I tried to upload a video and some pics but since I’m new to the forum I’m not allowed to post attachments. I’m hoping someone has experience with very low noise high torque motors. Maybe they just don’t exist and that’s why they stopped making these machines many years ag…

Hi @Dmzark , Thank you for providing these photos :slight_smile: What is the purpose of this machine? Just to watch it for relaxation? Or you plan to create a bigger scale? What noise levels are you looking to achieve here? What is the current noise level in dB?

Hello, My only plan is to try to reduce noise level so that this thing becomes what it’s supposed to be. An enjoyable relaxing thing to look at. The noise level kills that notion. I don’t know the db level. It sounds like a loud hair trimmer. Very whiny sounding which varies as t…

I saw now what’s on YouTube. This video for example: Wave Motion Machine, Kinetic Art - YouTube I see he used 15RPM motor.

I originally used 10 rpm motor and decided I decided I’d prefer slower so I went to 6 rpm then 5 rpm. 6 rpm gave the best visual result. All three motors exhibited the same amount of unacceptable noise to run in a quiet environment (which is the whole purpose for this thing - rel…

Yes, I thought also the same. Maybe you just use bigger motor and see what happens?

Yeah, maybe bigger will be better. Haven’t found one yet.

Thanks. Since my last post I’ve tried 2 other motors without success. I’ll give this a try
