    WWDC 2021 Keynote

    The Tech Doctors are back with their unedited examination of Apple’s 2021 World Wide Developers Conference Keynote presentation. There is lots of good information in this one.


    Portable Podcasting with PodTrak

    Portable Podcasting with PodTrak

    In this podcast, the Tech Doctors have the pleasure of speaking with Tim Cumings who is onboard to help us thoroughly examine the Zoom PodTrak P4. This is a small digital recorder, smartphone audio interface, and a USB interface for Mac or PC all in one portable device that weighs less than a pound.

    Tim and the Tech Doctors are confident that the PodTrak is a great choice for anyone who wants to record a podcast any time any place.

    The Tech Doctor known as David Woodbridge got so excited he bought a PodTrak during the recording of the podcast.

    If after listening to us you are wanting to learn more, the Tech Doctors encourage you to listen to the excellent podcast that Tim Cumings recorded for Jonathan Mosen. This podcast can be found


    Thanks for listening.

    An Apple Event Called Spring Loaded

    An Apple Event Called Spring Loaded

    In this podcast, the Tech Doctors tell you all about the Apple event that took place on April 20, 2021. It is always exciting to see how Apple keeps moving forward by constantly improving the products.

    The Tech Doctors do apologize for the unwanted guest called a leaf blower. Sorry for the background noise.

    Four Hybrid Braille Displays

    Four Hybrid Braille Displays

    In this podcast, the tech doctors compare and contrast four forty cell Braille displays. All four are known as “hybrid” Braille displays. The term hybrid is used because these displays have some basic capabilities when not connected to another device but the built-in functions are not as robust as you might find in a standard Braille notetaker. For example, these devices have a basic text editor but if you need to do sophisticated word processing in Braille, you will need to connect the display to a computer, smartphone, or tablet to make use of that devices word processing capabilities.

    The tech doctors are excited about this hybrid approach because computers and smartphones are much more capable of doing the heavy lifting than are traditional notetakers. They are also excited because the interface between Braille displays and other devices is improving.

    Allison and David share their experiences and perceptions of the


    Which is available from


    American Printing House.

    The Mantis is the only one of the four displays that has a QWERTY keyboard rather than a Perkins style Braille keyboard.

    Robert and David are experienced users of the



    Hims Inc.

    The QBraille is unique in that it as a Braille keyboard for data entry along with QWERTY function and navigation keys. Therefore, the QBraille can act as both a Braille display and a QWERTY keyboard when connected to a computer.

    Robert discusses the

    Orbit Reader 40


    Orbit Research.

    Thanks to new and more affordable Braille Display technology that was developed by Orbit Research, the Orbit Reader 40 is an excellent hybrid display but at half the cost of the other three.

    Robert expresses appreciation to Roger Behm of

    Adaptive Information Systems Inc.

    for loaning him a Brailliant BI 40X which is a major player in the current generation of hybrid Braille displays. The Brailliant BI 40X is manufactured by


    It can be purchased either from Adaptive Information Systems or directly from HumanWare. I have had excellent experiences purchasing from Roger at Adaptive Information Systems.

    The tech doctors hope you enjoy this rather fast paced and lively comparison. These new displays have much to offer and they are all unique making it likely that at least one of them will meet your particular needs.

    Connecting the Dots

    Connecting the Dots

    In this Tech Doctor episode, the tech doctors have the pleasure of sitting down with Venkatesh Chari, the CEO of Orbit Research.

    Venkatesh explains how he found the right career for himself by combining his engineering talents with his desire to develop products that really help people.

    It was wonderful to learn about Orbit Research’s approach to developing affordable, high quality refreshable Braille displays.

    A Little Touch of Braille

    A Little Touch of Braille

    This Tech Doctor podcast begins with Allison letting us know that she is enjoying working with the Microsoft Surface Pro. She also tells us how she is now carrying two iPhones to meet her entertainment and communications needs. She is enjoying both the iPhone 12 Pro Max and the iPhone SE 2020.

    David tells us about how he has taken his product demonstrations to a new level by producing videos. Don’t worry, he is still providing excellent audio description in these videos.

    To check out the new videos, go to

    David’s Vision Australia Blog.

    Robert tells us that there is now a way to use SuperDuper to backup Macs that are running Big Sur. You can read all about this on the

    Shirt-Pocket Blog.

    Robert also lets us know that setting up the M1 Macs to work with the

    Rogue Amoeba products

    is fully accessible with VoiceOver.

    The remainder of the podcast is spent discussing electronic Braille. There is a lot happening with Braille these days.

    The Tech Doctors discuss the trend away from Notetakers and toward hybrid Braille displays which have some minimal note taking capabilities but mostly rely on a connected computer or mobile device to do the heavy lifting of making word processing, email, web browsing, and so on available in Braille.

    The Tech Doctors acknowledge that for this hybrid approach to work well, the interface between the Braille display and the computer or mobile device has to be consistent and reliable. The Tech Doctors feel that there is a bright future for this way of working with Braille but there are some growing pains to get through. The Tech Doctors are delighted, however, to see the cost of refreshable Braille coming down.

    The Tech Doctors are excited about several new Braille displays. They discuss the

    Mantis from APH,

    The Orbit Reader from Orbit Research,

    And the

    new Brailliant displays from HumanWare.
