Subject: [CentralOH] Watchy: An Open Hardware Smart Watch
Message-ID: <b4ddf0aa-4cd5-df69-e9ae-93b72b80ba6f@gmail.com>

Those of you who have been going to the dojos for the past few months 
have probably seen me messing
around with my ESP32 board as I learn MicroPython 
<http://docs.micropython.org/en/latest/esp32/quickref.html>; I have to 
say, it's been pretty fun.

I recently came across the project Watchy, on the 
eletronics-crowdfunding site crowdsupply 
(https://www.crowdsupply.com/sqfmi/watchy 
<https://www.crowdsupply.com/sqfmi/watchy>).
It pairs an e-ink display, ESP32, and battery in a wristwatch form for 
about $50.
It's projected to be released at the start of the summer (so that 
probably means next winter?).

They're keeping all designs and source code open 
(https://github.com/sqfmi/Watchy <https://github.com/sqfmi/Watchy>).
Software written in C++ not MicroPython, but I'm sure with enough 
creativity, this is correctable ;-).

I'm in for one, and thought some of you might also be interested in a 
hackable smart-watch where you can
control your data (and every other feature). It'd be fun to hack on 
these together at meetings.

There are a number of watches like that, though I'm not sure how many
of them run MicroPython.  I have this one:

Ohh, and that has a touch screen & speaker. You like it? Have you done 
anything with it? What's the battery life?

So the hardware itself seems pretty refined- this is the second
version of this watch.  (The first version had external I/O ports and
was stackable, but was not as attractive.)  The software, not so much,
 Battery life is measured in hours- I think I was able to get 12 hours
out of it- but it's been a while since I've tinkered with it.  Here is
the most popular firmware for it- very easy to build & upload using
Visual Studio Code & platformio.

Hi Pythonistas,

If you are looking for a book on algorithms in Python, here is a chance 
to win a free copy.  If you decide you like the book, you will need to 
sign up at Java Ranch (javaranch.com) and ask a question.  The best 
question(s) get a free eBook.

Java Ranch originally started out as a place for Java programmers to get 
together and help each other out.  It has evolved to help programmers of 
many languages.  In addition to the web site, it has a low volume 
mailing list (2 - 5 emails/mo.).  Occasionally yours truly pops on and 
responds to some of the questions asked.

Travis

Subject: [CentralOH] Web API usage demo
Message-ID: <CAGCtaoMvtA5jRSL_JBDB-7Sc2xsqExTnRWZ5oHhkcBtNkZ+RbQ@mail.gmail.com>

Hi, folks!  I did a little demo at Thursday's dojo of using requests to get
JSON data from a RESTful API, so here's the code:

import requests
BASE_URL = 'https://ghibliapi.herokuapp.com'
url = f"{BASE_URL}/people"
people = requests.get(url).json()
for person in people:
    print(person['name'])
    for film in person['films']:
        film_response = requests.get(film)
        print(f"    {film_response.json()['title']}")

Of course, you'll need to `pip install requests` first...

Every single time I see some of your code, you're using some new
feature of Python I've never seen before. I had to look up what the
f-strings were for.

Ha, glad to hear it!  f-strings are for *everything*.  They're really
wonderful... and also a little bit terrifying.  f-strings and all their
evolutionary ancestors in the string templating world would be a good dojo
topic, now that I think about it.

Hi, COHPy!  Can somebody convey my thanks to Jon Bennett for his great
threading presentation?  It helped my understanding quite a bit.

I'd love to reuse it at one of Dayton PyFri events, if his code is
available.

If his contact info and/or materials were already posted, sorry I missed it
- I didn't see it in the Gather chat or on the mailing list.

Thanks!
