My wife pointed out the "opinions on shaking" thread and a person had made a shaker from am old computer fan.
Loving messing around with electronics this is what I came up with.
I had a dinosaur computer just sitting in the closet. I took out the fan and went to work. I found a Jewelery box that my daughter was throwing out so I took it and gave it a spray painting and and started to work on it. I went and bought 4 springs and took off the lid placed it upside down attaching it to the springs. This gives it a bi-level. 5ml-30ml will slide into the bottom. I gave air holes for the fan to "breath". I used an old plug that I just had stashed away with my wires for the power supply, and an on/off switch.
