[sudo-discuss] sudo grain dispenser

anybody want to scheme on building a 2-4 grain gravity feed hopper to keep and dispense dry grains in 1/2C increments? i wanted to get one for myself but the prices are somewhat unreasonable. could probably be done with 1/4" plywood and acrylic in front, all laser cut and easily assembled... like this but with wooden sides and superior capacity: http://www.webstaurantstore.com/zevro-tso101-compact-white-dry-food-dispens… any interest in doing this? is this a thing people want and is worth building?
