I've been mixing my own juice for a while now and being the kind of guy who loves DIY projects watch INSTRUCTABLES web site all the time. There are tons of neat projects on there. The last project I made was a magnetic stirrer for mixing my e-juice. It was fun simple and works really well. Produces an evenly mixed juice. I scrounged and bought the parts and made it for about 35 bucks. I got most of my components from Radio Shack. it could be made cheaper sourcing most of the parts over the net. If you mix your own juice and always want a magnetic stirrer I highly recommend this project!
