Portable seed winnower

A couple of seasons ago I built a seed winnower from a design published at Real Seeds U.K. . It took a bit of work to get it right, and I never got mine to work very well with lettuce seed. Additionally, it took up a fair bit of room, and to set it up I had to dig out the household vacuum cleaner, and string a power cord outside.
Looking around the 'net a week ago, I came across some seed cleaner machines built by canary fanciers, to clean husks from seed - I think because birds tend to eat seed and leave the husks, meaning a lot of good seed gets thrown out with the husks. Google them on youtube if you want to see.
I had a bit of a think, played with the design and came up with a slightly modified one that is useful for the small batch seed cleaning I need.

Advantages of this one over the larger Real Seed one is that it's much smaller, and lighter making it much easier to set up, and therefore much more likely for me to bother using it. It has a variable speed, which is handy for different seed types, and it runs off a small 12 volt battery, so i can set it up almost anywhere.

So, here is a short video showing the design. Hope you like it.
