These videos show the Jaromatic opening 2 different bottles. They are large files, so it may take up to 30 seconds for them to load, depending on your connection.
The gear noise is because I used a double-thread worm driving a single-thread worm gear: that is all I could find in stock parts. A production appliance would have compatible gears in a lubricated enclosure, eliminating the gear noise.
12 minute video of Jaromatic, comparing it's features with the lids-off jar opener by Black & Decker and the open-up jar opener by Appliance Science. The video is apx. 55 megs, and takes time to load. I don't have the expertise to make it work better, so if it doesn't work correctly, send me your contact info and I will send you a disk.
