*April 2, 2025*

*Hearing Aids* - The Newest Technology Available Now (Gamota)

*April 9, 2025*

*Electrified Mobility* and its effect on the town. Popular models, price
trends, accessibility benefits, and safety risks. Discuss the adoption of
e-bikes and scooters in town over the past couple years and its impact
(e.g. proposals for a formal speed limit on the commuter bikeway, debates
over the creation of dedicated / mixed use paths when redesigning local
roads). (Rich Moffitt suggests)
* Why are people talking about “micromobility” now?
* What are e-bike classes (1, 2, 3) and what are the tradeoffs /
restrictions?
* What's the risk of battery fires on these things and how can I manage the
risks?
* Why are they popular now? (mainly because motor costs have come way down
and reliability has gone up, see video of hub motor production: E-Bike Hub
Motor Factory Tour in China ELECTRICBIKE.COM )
* Is it feasible to DIY build (sometimes, with considerations)

*SPECIAL NOTE -* *Links and supplementary materials for many of our
previous sessions are available online at http://lctg.toku.us/

If this email wasn't addressed to you and you would like to join the group,
or if you have a friend or colleague who might also be interested in
joining, it's easy.  Ask them to go to the group's wiki page at
http://LCTG.toku.us and follow the simple instructions under "Join the
Email List".  By being a member of the group you'll get reminders of
upcoming meetings and infrequent related messages. No advertising.  The
list is tightly managed.

·       Membership is free and given that all meetings are available on
Zoom you only need to be connected to the Internet to join. It's ok to join
from anywhere you can get a decent Internet connection.

·       We, the Lexington Computer and Technology Group, will meet
Wednesday at the usual 10AM Eastern Time online, using the Zoom Video
Conferencing Application, facilitated by Steve Isenberg. (If noted above,
we may also be at the Lexington Community Center.)

There is an instruction page at https://toku.us/zoomish but note that the
URL and phone number shown are examples.

To join our online meeting, sometime after 9:45 AM on Wednesday, choose one
of the following options:

·        If you have the Zoom application installed, start it and join
meeting with ID 972 6146 0830

·        From your browser, go to: https://zoom.us/j/97261460830

·        From a “dumb” telephone, call 1 646 876 9923 and enter meeting ID:
972 6146 0830

·        Once the connection is established, you may need to locate and use
the on-screen controls that turn on the sound and the video. You should be
able to see and hear others and they should be able to see and hear you, if
you have a camera and microphone (each of which you can unmute selectively).
