Wave motion machine base with variable speed and LED strip.

This my version of the Wave motion machine base for DIY. This version has variable speed and a LED strip. Its powered by a 15V power suply. It is inspired by this video by Techmoan and Hughes Wave Motion Machines LLC: See it here:

The Inner plate and the cam disc needs to be printed in PETG or other materials that withstands a littlebit more heat than PLA since the motor gets qite hot. The outer shell cab be printed in PLA. I used tree supports on the outer shell.

The motor on this is quite loud but it has been very usefull to have variable speed. The other and simpler version of this that runs on grid power is not so loud. So I would recomend building that instead if you want it simple and quiet. And if I was to do it again I would choose another color of the LED strip than blue. I would suggest white or warm white.

For the vessel you need to cut it so the outer dimmensions is 480mm x 80mm x 40mm to fit. I have built mine with Polycarbonate 4mm and glued it with both the acrylic glue that I have linked to and thick Superglue from Biltema and both was watertight. You need to sand the edges smooth and the dimmensions has to be correct to get it watertight. I have drilled one fill hole in each end and tapped it with an M8 thread and used a screw with an O-ring to plug the fill hole.

The two fluids is Natusan clear babyoil and pure water with blue foodcoloring added. Fill the vessel with a bit over one third with colored water and the rest with baby oil. Glue the pivot point to the vessel so that it rests at the base with equal overhangs on both sides. I have covered the cam disc with some elcrical cloth tape and added a piece of teflon tape at the contact point on the vessel to reduce friction.
