This gadget can dispense glass beads (or any other spherical things) of 3mm diameter one at a time. A video is posted at https://www.youtube.com/watch?v=LgEwp8v0wIc&feature=em-upload_owner
It is made from laser cut 3mm acryllic. It should be possible to scale it to fit bigger beads, but the material thickness should be adjusted accordingly.
I have considered adding a springload, but this will be some time in the future. Please let me know in the comments if you manage to do so before me.
