thingiverse

Goal: achieve a simple, low-cost, fool-proof mass-storage solution for phones and tablets. The "to-go" package should fit easily into a familiar cup, back-up photos, videos, and files without monthly cloud fees or privacy concerns. Play back movie and music libraries anywhere - no internet required. Stream files while Venti Ba-Cup is connected via USB or transfer files, disconnect and play. Use at home, on the road, in a plane, on a cruise, or even mount naturally in any car!

(b) The other end of the USB cable with male standard-A connector connected to the female standard-A female to microB female USB adapter (ingredient #4), attached to a separate retractable USB cable, then to the USB OTG connector, which will connect directly to an Android phone or tablet. (c) To maintain organization inside Venti Ba-Cup, use the built-in divider between retractable USB cables when positioning components. Make sure that both the 5V adapter (battery, AC power) and Venti cup can fit snugly under the lid with full mobility. Purchase Nexus Media Importer app on Google Play: https://play.google.com/store/apps/details?id=com.homeysoft.nexususb.importer for accessing NTFS storage or other apps like it. Operating Procedure: (1) Lift off Venti Ba-Cup's lid and power on hard drive via one of the retractable USB cables. (2) Power on phone/tablet before attaching the second USB cable (the one with OTG attached to your Android device). Otherwise, it may not be recognized by phone/tablet or USB drive. (3) Once powered up for disk drives and turned off but fully booted from mobile phones as Venti cups can only accept both sources being available during power usage prior connection so all works properly once both running properly in addition also after done everything will turn back onto what was going previous; no need more then usual process!
