RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while typing up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...

Design Your Custom OwnFone™ - Even with a Braille Keypad!

OwnFone™ Homepage - RF CafeCustom designs for your cellphone's cover are not new, but this model from OwnFone™ has a unique twist - its case is fabricated with a 3D printer that can create a keypad with Braille buttons for the blind (or sight-impaired). The OwnFone™ concept is one of simplicity and special use since it only functions as a phone. You cannot even receive voice mails or text messages on it (OMG!). If you choose the Braille, Child, or Senior model, it only accommodates up to four (4) buttons, each with a specific phone number to be dialed, but a standard 3x4 numeric keypad is also an option. The OwnFone's targeted audience is users with special needs, or maybe as a novelty / vanity phone to show off to friends.

OwnFone with Custom RF Cafe Image - RF CafeAn option with all phone models is to upload custom graphics for the front and back of the phone. I did a quick design to test out what you get to see prior to committing to a purchase (click image to the left). You can provide separate images for each button as well as an overall theme. It would be nice if OwnFone provided a template for each layout that can be modified while taking into account the areas that they occupy. A work-around is to do a screen capture of the layout you plan to use, then stretch it into the 620x1000-pixel space they allow for the graphics. Create your design over top of it, then delete the screen capture.

At this time the phones only work in the UK and Northern Ireland network1 and apparently you need to purchase your service plan through OwnPhone initially. Because of the localized 3D production capability (as opposed to commitment to large volume orders and inventory) cost is very reasonable at less than $100US.
